Ainda está longe de ser completo a compreensão completa dos complexos ecossistemas dos Neotrópicos, embora eles tenham sido estudados desde a primeira expedição dos naturalistas do velho mundo Macrgrave, Humboldt, Spix, Darwin, Bates e Müller. Os objetivos e escopo do periódico são, além de pesquisas taxonômicas e zoogeográficas, análises de comunidades animais e sua relação com condições ambientais bióticas e abióticas. Isto inclui a fauna de ecossistemas terrestres e de água doce nos Neotrópicos. Contribuições que representam pesquisas originais e mini-revisões são bem-vindas.

Todos os artigos de pesquisa publicados neste periódico passaram por uma rigorosa revisão, baseada em uma triagem inicial do editor e por revisão anônima por experientes revisores independentes.

Factors affecting home range size and overlap in Akodon azarae (Muridae: Sigmodontinae) in natural pasture of Argentina

PRIOTTO, J.W.; STEINMANN, A.R. 1999. Factors affecting home range size and overlap in Akodon azarae (Muridae: Sigmodontinae) in natural pasture of Argentina. Acta Theriologica 44(1):37-44.

Abstract. Differences in home range size in relation to sex, age, breeding and non-breeding periods were studied. Home range size and overlap were examined at different densities values in populations of Akodon azarae (Fischer, 1829) on railway banks in southern Córdoba Province (Argentina). The sampling was carried out between October 1994, and February 1997, using the capture-mark-recapture method. Home range size in A. azarae was determined by sex and breeding period, and it was independent of the observed density values. Home range size of males was always larger than that of females. Increase of population density during the breeding period affected the degree of intersexual overlap of home range.

Response of leopards to re-introduced tigers in Sariska Tiger Reserve, Western India

MONDAL, K.; GUPTA, S.; BHATTACHARJEE, S.; QURESHI, Q; SANKAR, K. 2012. Response of leopards to re-introduced tigers in Sariska Tiger Reserve, Western India. International Journal of Biodiversity and Conservation 4(5):228-236. doi: 10.5897/IJBC12.014

Abstract. Tigers got exterminated from Sariska Tiger Reserve before 2005. After that, five tigers were re-introduced to Sariska during 2008 to 2010. The present study compared the abundance, site occupancy and temporal activity pattern of leopard before and after tiger re-introduction. The population of leopard was estimated by mark-recapture technique using camera traps during 2008 to 2010 in an effective trapping area of 223.3 km2. Before tiger re-introduction (2008), the leopard density was estimated to be 7.6±0.6 (SE) /100 km2 and after tiger reintroduction it was 6.2±0.8 /100 km2(2009) and 3.1±0.4 /100 km2 (2010). It was observed that the density of leopard declined significantly (Two sample T-Test; P = 0.0002) from 2008 to 2010. Rate of site occupancy was calculated through site-wise capture history of leopard obtained from camera traps. Before tiger re-introduction the probability of site utilization of leopard was 0.75, while after tiger re-introduction probabilities of site utilization of leopard and tiger were estimated at 0.54 and 0.52 respectively and the co-occurrence of both the species was 0.51. Temporal activity patterns of tiger and leopard were investigated from photo captures. Prior to the release of tigers, mean activity time of leopard was 20: 57 h (95% CI 20: 19 to 22: 53) but shifted to 22: 35 h (21: 02 to 01: 25 h) after tiger release (Watson’s U2 test: p<0.005). The present study showed that there was a decline in the leopard population after tiger re-introduction and considerable segregation between the two carnivores along the spatial and temporal axes.

Karyology of the Atlantic forest rodent Juliomys (Cricetidae): a new karyotype from southern Brazil

PARESQUE, R.; CHRISTOFF, A.U.; FAGUNDES, V. 2009. Karyology of the Atlantic forest rodent Juliomys (Cricetidae): a new karyotype from southern Brazil. Genetics and Molecular Biology 32:301-305.

Abstract. Juliomys is a small rodent from the family Cricetidae which inhabits the Atlantic forest and forests from Argentina to eastern Brazil. The three species recognized so far have different karyotypes. In this paper, we describe a new karyotype with 2n = 32, FN = 48 found in Juliomys specimens from a high-altitude area in the Atlantic forest of southern Brazil. The karyotype was analyzed after G- and C-banding and silver staining of the nucleolus organizer regions (Ag-NOR) and its G-banding patterns were compared with those of the newly described species Juliomys ossitenuis (2n = 20, FN = 36). The 2n = 32 karyomorph presented peculiar features and was very different from those of the other species of the genus: J. pictipes (2n = 36, FN = 34), J. rimofrons (2n = 20, FN = 34) and J. ossitenuis (2n = 20, FN = 36). Differences were mostly due to centric and tandem fusions, pericentric inversion and loss of hetero-chromatin. The karyotype represents a powerful tool to differentiate Juliomys species and our data suggest that the karyotype described herein belongs to a new species.

Livro: Mamíferos do Rio Grande do Sul

Depois de muito tempo, finalmente teremos um livro de Mamíferos do Rio Grande do Sul. O livro já está pronto, mas para sua impressão ainda será preciso apoio dos pesquisadores. Por isso a equipe de edição abriu um Projeto onde qualquer pessoa pode fazer doações para que o projeto se torne realidade. E as doações são recompensadas de diversas maneiras. Doando R$ 50,00, por exemplo, você recebe um exemplar do livro e um adesivo do projeto. Doações maiores conferem um livro ao doador e mais uma doação de exemplares do livro para instituições de pesquisa.

Passe nesse link para maiores e informações, e faça sua doação para apoiar o projeto e receber um exemplar:

Particularmente acho o projeto muito bem-vindo. Até o momento o único exemplar de livro de mamíferos do Rio Grande do Sul é o "Mamíferos Silvestres do RS", do Flávio Silva. Mas hoje o livro encontra-se muito desatualizado. Há anos ouço uma promessa de um livro de mamíferos do RS, mas até hoje nada foi publicado. Portanto, acho que o Mamíferos do Rio Grande do Sul, com organização de Gislene Gonçalves, é um título muito bem-vindo e necessário.

Use of vertical space by small mammals in gallery forest and woodland savannah in south-western Brazil

HANNIBAL W.; CÁCERES NC. 2010. Use of vertical space by small mammals in gallery forest and woodland savannah in south-western Brazil. Mammalia 74: 247-255. doi: 10.1515/MAMM.2010.007

Abstract. We examined the community composition and abundance of small mammals in the vertical strata of gallery forests and woodland savannahs in south-western Brazil. Captures were carried out during the winter and summer months of 2006/2007. Traps were set in three transect lines per habitat, with 10 capture stations on each line. Each station had three traps: on the ground, in the understorey (2–3 m in height), and in the canopy (8–10 m) in each physiognomy. With an effort of 3600 trap-nights, 11 species of small mammals were captured, which were distributed differently regarding the forest physiognomies and utilisation of vertical strata. The species showed a high degree of habitat segregation in the two physiognomies, with only the climbing-rat Rhipidomys macrurus found in both habitats. The correspondence analysis revealed that Caluromys philander occurred mostly in the canopy; Cryptonanus agricolai, Marmosa murina, and Oecomys bicolor in the understorey; and Gracilinanus agilis and Nectomys rattus on the ground. The utilisation of traps in different strata increased species richness in the Cerrado biome, showing that the small-mammal community is distributed along the vertical complexity of the forest and even in different physiognomies, enabling more species to coexist.

geomorph: an R package for the collection and analysis of geometric morphometric shape data

ADAMS, D.C.; OTÁROLA-CASTILLO, E. 2013. geomorph: an R package for the collection and analysis of geometric morphometric shape data. Methods in Ecology and Evolution 4:393-399. doi: 10.1111/2041-210X.12035.

Abstract. Many ecological and evolutionary studies seek to explain patterns of shape variation and its covariation with other variables. Geometric morphometrics is often used for this purpose, where a set of shape variables are obtained from landmark coordenates following a Procruster superimaposition.
We introduce geomorph: a software package for performing geometric morphometric shape analysis in the R statistical computing environment.
Geomorph provides routines for all stages of landmark-based geometric morphometric analysis in two and three-dimensios. It is an open source package to read, manipulate, and digitize landmark data, generate shape variables via Procruster analysis for points, curves and surfaces, perform statistical analyses of shape variation and covariation, and to provide graphical depictions of shape and patterns of shape variation. An important contribution of geomorph is the ability to perform Procrustes superimposition on landmark points, as well as semilandmark from curves and surfaces.
A wide range of statistical methods germane to testing ecological and evolutionary hypotheses of shape variation are provided. These include standard multivariate methods such as principal components analysis, and approaches for multivariate regression and group comparison. Methods for more specialized analyses, such as for assessing shape allometry, comparing shape trajectories, examining morphological integration, and for assessing phylogenetic signal, are also included.
Several functions are provided to graphically visualize results, including routines for examining variation in shape space, visualizing allometric trajectories, comparing specific shapes to one another and for plotting phylogenetic changes in morphospace.
Finally, geomorph participates to make available advanced geometric morphometric analysis through the R statistical computing platform.

An introduction to Marmosops (Marsupialia: Didelphidae), with the description of a new species from Bolivia and notes on the taxonomy and distribution of other bolivian forms

VOOS, R.S.; TARIFA, T.; YENSEN, E. 2004. An introduction to Marmosops (Marsupialia: Didelphidae), with the description of a new species from Bolivia and notes on the taxonomy and distribution of other bolivian forms. American Museum Novitates 3466:1-40.

Abstract. In order to facilitate much-needed revisionary research on Marmosops, we summarize the currently accepted species-level taxonomy, provide full bibliographic citations for original descriptions of all 36 included nominal taxa, map their type localities, and list their type material (if known). We rediagnose the genus Marmosops, compare it with three other didelphid genera to which misidentified specimens of Marmosops have often been referred, and review the phylogenetic evidence that Marmosops is monophyletic. After describing a new species from the eastern-slope montane forest of Bolivia, we review the taxonomy of other Bolivian congeners based on morphological characters and published cytochrome-b gene sequences. Among our taxonomic results, we synonymize albiventris Tate (1931), dorothea Thomas (1911), and yungasensis Tate (1931) with M. noctivagus (Tschudi, 1845). By contrast, M. ocellatus (Tate, 1931), currently considered a synonym of dorothea, appears to be a valid species. Whereas published range maps of Bolivian species of Marmosops are demonstrably based on misidentified material and show little correspondence with known environmental factors, locality records based on specimens examined for this report make much more eco-geographic sense.

Rural roads as barriers to the movements of small mammals

MACPHERSON, D.; MACPHERSON, J.L.; MORRIS, P. 2011. Rural roads as barriers to the movements of small mammals. Applied Ecology and Environmental Research 9(2):167-180.

Abstract. Over the last 50 years increasing fragmentation of habitats has occurred due to road building. Fragmenting a large population into smaller ones can have a negative effect on population demography. In England much small mammal habitat occurs in suburban and rural areas where the majority of roads are either single track or two lanes, and traffic density is light. This study investigated the effect of minor roads on the movements of two small mammals, the wood mouse (Apodemus sylvaticus) and bank vole (Myodes glareolus). Capture-Mark-Recapture was used to study movements beside and across rural roads of two different widths. The results suggest that even small roads less than 6metres wide, with relatively little traffic, do act as partial barriers for these small mammals, reducing their movement between habitats on either side of the road. It is evident that island populations are being created as a result of road construction, even access roads within nature reserves.

The historical bridge between the Amazon and the Atlantic Forest of Brazil: a study of molecular phylogeography with small mammals

COSTA, L.P. 2003. The historical bridge between the Amazon and the Atlantic Forest of Brazil: a study of molecular phylogeography with small mammals. Journal of Biogeography 30:71-86.

Abstract.
Aim. To examine how the genetic diversity of selected taxa of forest-dwelling small mammals is distributed between and within the major rain forest domains of Amazonia and Atlantic Forest and the intervening interior forests of Brazil, as inferred by the relationships between gene genealogies and geography. I also addressed the historical importance of the central Brazilian forests in connecting Amazon and Atlantic Forest populations of rodents and marsupials.
Methods. I evaluated variation in the mitochondrial cytochrome b gene to estimate the levels of sequence divergence between those taxa occurring throughout the Amazon, Atlantic Forest, and forests in the Cerrado and Caatinga regions. I inferred the hierarchical relationships between haplotypes, populations and formal taxa using the cladistic approach of maximum parsimony. I compared areas and the clades identified by superimposing cladograms on the geographical distribution of samples. The degree of concordance both in phylogeny and the depth of the nodes in these phylogenies, in addition to patterns of geographical distribution of clades, permitted me to make inferences on how, when and where the taxa differentiated.
Results. Sequence similarity is often greater between samples from the Atlantic Forest and either Amazon or central Brazilian forests than it is within each of the two rain forest domains. The Atlantic Forest clades are either not reciprocally monophyletic or are the sister group to all the other clades. There is some indication of northern and southern components in the Atlantic Forest. Given the geographical distribution of clades and the relatively deep levels of divergence, the central Brazilian area does not behave as a separate region but is complementary to either Amazon or Atlantic Forest. Patterns of area relationships differ across taxa, suggesting that different processes and ⁄or historic events affected the diversification within each lineage.
Main conclusions. The Amazon and the Atlantic forests are not exclusive in terms of their small mammal faunas; both overlap broadly with taxa occurring in gallery forests and dry forests in central Brazil. Central Brazilian forests are an integral part of the evolutionary scenario of lowland small mammals, playing an important role as present and past habitats for rain forest species. Therefore, representatives from this area should always be included in analyses of the evolutionary history of lowland rain forest faunas. The incongruence of branching patterns among areas is in agreement with recent results presented for Neotropical passerine birds and indicates that a single hypothesis of Neotropical area relationships is unlikely. These findings reinforce the idea that speciation in the Neotropics will not be explained by any single model of vicariance or climatic changes.

The maned wolf in the ecotone between forest and grasslands at the limits of its distribution in a subtropical environment

MARQUES, R.V.; FABIÁN, M.E. 2013. The maned wolf in the ecotone between forest and grasslands at the limits of its distribution in a subtropical environment. Bioscience Journal 29(3):751-759.

Abstract. The maned wolf (Chrysocyon brachyurus) is a neotropical canid that is considered near threatened by the IUCN, vulnerable in Brazil and critically endangered in the state of Rio Grande do Sul. The Araucaria High Plains have coverage of Atlantic forest mixed in with open areas and small wetland areas and are at one of the limits of the range of the maned wolf. The objectives of this article are to demonstrate that, although rare, the maned wolf does still occur in the Araucaria High Plains and to discuss the relevance of conservation efforts in areas in which the occurrence of threatened species is borderline. Data collection took place between March of 1999 and December of 2010 with a total sampling effort of 11,431 trap-days. After 10 years in which there were no corroborated records, the species was caught by camera traps in the São Francisco de Paula National Forest in November of 2009. This is a protected area with forest vegetation and is not considered the species’ typical habitat. The open areas in this region are being taken over by agriculture and silviculture of exotic species.

Microhabitat of small mammals at ground and understorey levels in a deciduous, southern Atlantic Forest

MELO, G.L.; MIOTTO, B.; PERES, B.; CÁCERES, N.C. 2013. Microhabitat of small mammals at ground and understorey levels in a deciduous, southern Atlantic Forest. Anais da Academia Brasileira de Ciências 85(2):727-736.

Abstract. Each animal species selects specific microhabitats for protection, foraging, or micro-climate. To understand the distribution patterns of small mammals on the ground and in the understorey, we investigated the use of microhabitats by small mammals in a deciduous forest of southern Brazil. Ten trap stations with seven capture points were used to sample the following microhabitats: liana, fallen log, ground litter, terrestrial ferns, simple-trunk tree, forked tree, and Piper sp. shrubs. Seven field phases were conducted, each for eight consecutive days, from September 2006 through January 2008. Four species of rodents (Akodon montensis, Sooretamys angouya, Oligoryzomys nigripes and Mus musculus) and two species of marsupials (Didelphis albiventris and Gracilinanus microtarsus) were captured. Captured species presented significant differences on their microhabitat use (ANOVA, p = 0.003), particularly between ground and understorey sites. Akodon montensis selected positively terrestrial ferns and trunks, S. angouya selected lianas, D. albiventris selected fallen trunks and Piper sp., and G. microtarsus choose tree trunks and lianas. We demonstrated that the local small-mammal assemblage does select microhabitats, with different types of associations between species and habitats. Besides, there is a strong evidence of habitat selection in order to diminish predation.

Support diameter, incline, and vertical movements of four didelphid marsupials in the Atlantic forest of Brazil

CUNHA, A.A.; VIEIRA, M.V. 2002. Support diameter, incline, and vertical movements of four didelphid marsupials in the Atlantic forest of Brazil. Journal of Zoology, London 258:419-426.

Abstract. Didelphids use vertical strata in different ways, suggesting the existence of a wider variety of niches than simply arboreal or terrestrial. This variety could be related to the differential ability to deal with support diameters and inclines, and might be important for the coexistence of species in local assemblages. From data obtained with the spool-and-line technique, the use of the vertical space and above-ground supports is described in four species of an assemblage of didelphid marsupials in south-east Brazil. The stratification in this and other assemblages in the Atlantic forest and in the Amazon is also compared. Animals were trapped in Serra dos Órgãos, state of Rio de Janeiro, and equipped with a spool-and-line device before release. The paths were tracked by measuring variables related to support diameter, incline, distance and height moved above ground. The diameter of supports used was positively related to body size, and the incline to the dominant direction of movement (horizontal vs vertical). The more cursorial species, Metachirus nudicaudatus, only once moved above ground in > 3200 m of paths followed. Didelphis aurita moved mostly on the ground, but was the only species that occasionally reached the canopy. Philander frenata also moved mostly on the ground, occasionally used the understorey, but never reached the canopy. The more arboreal species, Marmosops incanus, moved mostly in the understorey, but never in the canopy. This pattern of stratification is similar to that observed in other sites in the Atlantic forest and in the Amazon.

Hábitos alimentares e uso de abrigos por Chrotopterus auritus (Chiroptera, Phyllostomidae)

WITT, A.A.; FABIÁN, M.E. 2010. Hábitos alimentares e uso de abrigos por Chrotopterus auritus (Chiroptera, Phyllostomidae). Mastozoología Neotropical 17(2):353-360.

Abstract. Food habits and use of roosts by Chrotopterus auritus (Chiroptera, Phyllostomidae). Chrotopterus auritus (Peters, 1856) (Phyllostomidae, Chiroptera) is the only species of carnivorous bat recorded in Rio Grande do Sul state. In this work we identified the diet items and observed their spatial distribution within roosting sites at daytime. We monitored seven caves, every fifteen days, from may/2002 to april/2003, in Machadinho and Barracão counties, Rio Grande do Sul state, Brazil. The diet was inferred from fecal samples (n=67) and food remains (n=63). Mammals, birds and arthropods, composed the diet of the C. auritus. C. auritus did not show preference by food items, such as mammals, birds or arthropods, because there were no significant differences among them in fecal samples. The result was similar when comparing the presence of these items between seasons. Rodents, Passeriformes and Coleopterans were the prevailing items in the diet of the C. auritus. Fruits were consumed occasionally, about 5.9% of the total of the samples. C. auritus was, during the whole study period, present in the studied caves, varying in number of individuals and shelters. Cohabitation with Desmodus rotundus and Myotis nigricans was observed.

Trend of the Yellowstone grizzly bear population

EBERHARDT, L.L.; BREIWICK, J.M. 2010. Trend of the Yellowstone grizzly bear population. International Journal of Ecology, v. 2010, Article ID 924197, 5 pages. doi: 10.1155/2010/924197.

Abstract. Yellowstone’s grizzlies (Ursus arctos) have been studied for more than 40 years. Radiotelemetry has been used to obtain estimates of the rate of increase of the population, with results reported by Schwartz et al. (2006). Counts of females with cubs-of-the-year “unduplicated” also provide an index of abundance and are the primary subject of this report. An exponential model was fitted to n = 24 such counts, using nonlinear leastsquares. Estimates of the rate of increase, r, were about 0.053. 95% confidence intervals, were obtained by several different methods, and all had lower limits substantially above zero, indicating that the population has been increasing steadily, in contrast to the results of Schwartz et al. (2006), which could not exclude a decreasing population. The grizzly data have been repeatedly mis-used in current literature for reasons explained here.

A radio tracking study of home range and movements of the marsupial Micoureus demerarae (Thomas) (Mammalia, Didelphidae) in the Atlantic forest of south-eastern Brazil

JUNIOR, E.A.M.; CHIARELLO, A.G. 2005. A radio tracking study of home range and movements of the marsupial Micoureus demerarae (Thomas) (Mammalia, Didelphidae) in the Atlantic forest of south-eastern Brazil. Revista Brasileira de Zoologia 22(1):85-91.

Abstract. From August 2001 to July 2002 the home range and movements of seven Micoureus demerarae (Thomas, 1905) (three males and four females) were investigated using radio tracking in the União Biological Reserve, state of Rio de Janeiro, south-eastern Brazil. A total of 436 locations was obtained and home range estimated with fixed Kernel (95% of data points), and minimum convex polygon (MCP) methods, with 100 and 95% of data points. Male home ranges estimated by MCP (100%) ranged from 5.4-24.2 ha and females from 0.3-10.7 ha. Corresponding figures calculated with Kernel (95%) were 4-10.9 ha for males and 1.3-5.9 ha for females. Animals travelled on average 423 m/night, with males travelling significantly further (582.8 m/night) than females (335.1 m/night) (t test, t = 3.609, p = 0.001). We concluded that radio tracking produced much larger home ranges than those estimated with traditional live-trapping techniques, suggesting that the latter might underestimate ranging when the area covered with traps is relatively small (ca. 1 ha or less). Radio tracking also indicated that M. demerarae, although predominantly arboreal and weighting only ca. 130 g., has movements similar in magnitude to larger-sized terrestrial didelphimorph marsupials, such as Didelphis Linnaeus, 1758, Philander Linnaeus, 1758 and Metachirus (Desmarest, 1817).

Short-term fire effects on small mammal populations and vegetation of the Northern Chihuahuan Desert

MONASMITH, T.J.; DEMARAIS, S.; ROOT, J.J.; BRITTON, C.M. 2010. Short-term fire effects on small mammal populations and vegetation of the Northern Chihuahuan Desert. International Journal of Ecology, v. 2010, Article ID 189271, 9 pages. doi: 10.1155/2010/189271.

Abstract. Fire is an important ecological factor in semidesert grass-shrub community dynamics, but there is a lack of designed field experiments documenting effects on vegetation and small mammals.We document effects of June prescribed fire on vegetation and small mammals on 20, 25-ha study areas in the Northern Chihuahuan Desert of Southern New Mexico, USA one month and one year posttreatment. Canopy cover of shrubs and grasses recovered to 68 and 27% of the preburn canopy cover, respectively, after one year. Prescribed burns during June enhanced short-term forb production by reducing competition from grasses and shrubs. Thirty thousand trap-nights yielded 1744 captures of 766 individuals of 15 small mammal species. Burns did not affect small mammal species richness and species diversity. Relative abundance of Merriam’s kangaroo rats (Dipodomys merriami) was 91% greater on burned sites than on control sites one year postburn. Silky pocket mouse (Perognathus flavus) relative abundance was 221% greater on burned sites one year postburn. Chihuahuan Desert pocket mice (Chaetodipus eremicus) responded negatively to the fire, with relative abundance 170% greater on control sites (P = .080). Burning produced short-term benefits for two heteromyids, Merriam’s kangaroo rats and silky pocket mice.

Interactions between short-beaked common dolphin (Delphinus delphis) and the winter pelagic pair-trawl fishery off Southwest England (UK)

BOER, M.N.; SAULINO, J.T.; LEOPOLD, M.F.; RIJNDERS, P.J.H.; SIMMONDS, M.P. 2012. Interactions between short-beaked common dolphin (Delphinus delphis) and the winter pelagic pair-trawl fishery off Southwest England (UK). International Journal of Biodiversity and Conservation 4(13):481-499. doi: 10.5897/IJBC12.016

Abstract. During offshore and onshore studies (2004 to 2009), the interactions between pair-trawls and shortbeaked common dolphins (Delphinus delphis) were studied to better understand the impact of bycatch. A ‘hotspot’ area where pair-trawls overlapped with high dolphin abundance was identified. We made comparisons between boat-based data collected in absence and presence of pair-trawlers. The relative abundance and group-size of dolphins was significantly higher in the presence of pair-trawlers. Dolphins were observed associating with towing and hauling procedures. Significantly, more carcasses occurred in areas with hauling-activity than those without. Body-temperatures obtained from carcasses found near operating pair-trawlers indicated that bycatch mostly occurred at night. During necropsy studies, difficulties were encountered in identifying the fishing-gears responsible. Strandings data highlighted that the number of dead stranded dolphins was probably much higher than previously reported and there was a significant difference in the age and gender-composition of carcasses. Mature/sub-adult males appeared at greater risk from entanglement in pair-trawls offshore, whilst females with young appeared more vulnerable to inshore gillnets. Our findings show that the overlap between pelagic fisheries and the common dolphin hotspot is causing direct mortality through bycatch and, together with recent range-shifts, may have contributed to a localised decline of this species in this winter hotspot since 2007.

Activity patterns of the culpeo fox (Lycalopex culpaeus megellanica) in a non-hunting area of northwestern Patagonia, Argentina

MONTEVERDE, M.J.; PIUDO, L. 2011. Activity patterns of the culpeo fox (Lycalopex culpaeus megellanica) in a non-hunting area of northwestern Patagonia, Argentina. Mammal Study 36:119-125.

Abstract. The culpeo fox is the largest native canid in Patagonia. The majority of past studies on culpeo foxes have focused on trophic ecology, population dynamics, natural history, competitive interactions, management, and habitat use. Little work has been done on determining activity patterns of the fox and thus, conclusions regarding culpeo fox activity patterns have been based on limited data. The objective of our study was to determine culpeo fox activity patterns in a protected area (Lanín National Park, Argentina) using “camera-traps” to test the hypothesis that the culpeo fox is still nocturnal in non-hunting areas. Data were collected from October 2008 through May 2009 at 29 infrared triggered camera stations. We obtained 1,261 culpeo fox photos of which 234 were used for analyses. Diet was studied from 34 culpeo fox scats. Culpeo foxes were most active during nighttime (>70% of the records) confirming the general patterns obtained in other studies. Additionally, examination of culpeo fox scats revealed that they mostly preyed on nocturnal small mammals. The present study offers evidence against the widespread assumption that nocturnal activity of this species is a behavioral response to human harassment, as it was conducted in a protected area where culpeo foxes are not hunted. Instead, their nocturnal behavior may be related to prey activity patterns.

The role of forest structure, fragment size and corridors in maintaining small mammal abundance and diversity in an Atlantic forest landscape

PARDINI, R.; SOUZA, S.M.; BRAGA-NETO, R.; METZGER, J.P. 2005. The role of forest structure, fragment size and corridors in maintaining small mammal abundance and diversity in an Atlantic forest landscape. Biological Conservation 124:253-266. doi:10.1016/j.biocon.2005.01.033.

Abstract. Using the abundance and distribution of small mammals at 26 sites in an Atlantic forest landscape, we investigated how species abundance and alpha and beta diversity are affected by fragment size and the presence of corridors. To account for the variability in forest structure among fragments, we described and minimized the influence of foliage density and stratification on small mammal data. Sites were distributed among three categories of fragment size and in continuous forest. For small and medium-sized categories, we considered isolated fragments and fragments connected by corridors to larger remnants. Small mammal abundance and alpha and beta diversity were regressed against site scores from the first axis of a Principal Component Analysis on forest structure variables. Residuals were used in analyses of variance to compare fragment size and connectivity categories. Forest structure influenced total abundance and abundance of some species individually, but not the diversity of small mammal communities. Total abundance and alpha diversity were lower in small and medium-sized fragments than in large fragments and continuous forest, and in isolated compared to connected fragments. Three species were less common, but none was more abundant in smaller fragments. At least one species was more abundant in connected compared to isolated fragments. Beta diversity showed an opposite relationship to fragment size and corridors, increasing in small and isolated fragments. Results highlight the importance of secondary forest for the conservation of tropical fauna, the hyper-dynamism of small isolated fragments and the potential of corridors to buffer habitat fragmentation effects in tropical landscapes.

The pampas cat group (genus Lynchailurus Severtzov, 1858) (Carnivora: Felidae), a systematic and biogeographic review

GARCIA-PEREA, R. 1994. The pampas cat group (genus Lynchailurus Severtzov, 1858) (Carnivora: Felidae), a systematic and biogeographic review. American Museum Novitates 3096:1-36.

Abstract. A systematic study of 86 specimens of South American cats formerly known as Felis colocolo reveals three species, in addition to a new subspecies described herein. The three species are grouped in the genus Lynchailurus on the basis of shared character states. Lynchailurus pajeros occurs on high-elevation steppes from Ecuador to Bolivia and Argentina (eastern slope of the Andes), and farther south in Argentina into lowland steppe, shrubland, and dry forest habitats. Its southern limit is Patagonia (Argentinean and Chilean). Lynchailurus braccatus is found in Brazil, Paraguay, and Uruguay, where it occupies humid and warmer grassland and forested areas, at moderate elevations. Lynchailurus colocolo occurs in subtropical forests at middle elevations in central Chile, and in high-elevation steppes in northern Chile on the western slope of the Andes. The latter species may be endangered, because its distribution is limited. Assigned subspecies are as follows: L. pajeros budini and L. p. crespoi, in northwestern Argentina; L. p. crucinus, in southern Argentina and Chile; L. p. garleppi, in Peru; L. p. pajeros, in central Argentina; L. p. steinbachi, in Bolivia; L. p. thomasi, from Ecuador; L. braccatus braccatus, in southwestern Brazil and Paraguay; L. b. munoai, in Uruguay and southern Brazil; L. colocolo colocolo, in central Chile; and L. c. wolffsohni (new subspecies), in northern Chile.

Using the dead to monitor the living: can road kill counts detect trends in mammal abundance?

GEORGE, L.; MACPHERSON, J.L.; BALMFORTH, Z.; BRIGHT, P.W. 2011. Using the dead to monitor the living: can road kill counts detect trends in mammal abundance? Applied Ecology and Environmental Research 9(1):27-41.

Abstract. Counts of animal corpses resulting from road traffic collisions can give useful information on changes in animal abundance if there is a correlation between the population density of the species in neighbouring habitats and the number of road kills observed. Collection of data on mammal road casualties can be carried out by untrained volunteers; it can be collected across large areas; and it is cost effective in terms of time and expense. We carried out a study to determine if road casualty data can be used to monitor mammal abundance and distribution using one of the most commonly recorded road casualty species in the UK, the rabbit (Oryctolagus cuniculus), as an example. We found a direct relationship between the numbers of rabbit road casualties and the numbers living in the wider landscape. Nearly 60% of the deviance in the live rabbit density index could be explained using only rabbit road casualty, landclass group and traffic flow data. Therefore the use of road casualty data is a cost effective method of monitoring rabbits and, by implication, other species over a large area in the UK, and is a highly effective means of monitoring terrestrial mammals.

Do invasive fire ants affect habitat selection within a small mammal community?

HOLTCAMP, W.N.; WILLIAMS, C.K.; GRANT, W.E. 2010. Do invasive fire ants affect habitat selection within a small mammal community? International Journal of Ecology, v. 2010, Article ID 642412, 7 pages. doi: 10.1155/2011/642412.

Abstract. Animals must balance foraging with the need to avoid predators and risky habitats that decrease their fitness, and at the same time they must cope with competitors vying for habitat and resources. We examined how habitat selection and population density of four native small mammals were altered by the presence of red imported fire ants (Solenopsis invicta). When population size was low, hispid cotton rats (Sigmodon hispidus) and pigmy mice (Baiomys taylori) as well as white-footedmice (Peromyscus leucopus) used the “safe”, low fire ant habitat, as predicted by theories of density-dependent habitat selection. However, as fire ant population sizes expanded, cotton rats appeared to displace pigmy mice into the fire ant-dense grassland drainage while white-footed mice (Peromyscus leucopus) displaced all the other small mammals from low fire ant forest/brushland habitat.

Activity, habitat use, density, and reproductive biology of the crab-eating fox (Cerdocyon thous) and comparison with the pampas fox (Lycalopex gymnocercus) in a Restinga area in the southern Brazilian Atlantic Forest

FARIA-CORRÊA, M.; BALBUENO, R.A.; VIEIRA, E.M.; FREITAS, T.R.O. 2009. Activity, habitat use, density, and reproductive biology of the crab-eating fox (Cerdocyon thous) and comparison with the pampas fox (Lycalopex gymnocercus) in a Restinga area in the southern Brazilian Atlantic Forest. Mammalian Biology 74:220-229.

Abstract. The ecology and reproductive biology of the crab-eating fox (Cerdocyon thous) and the pampas fox (Lycalopex gymnocercus) were studied in Itapuã State Park, an Atlantic Forest fragment. In this study we describe their activity patterns (diel, lunar, and seasonal), reproductive period, density, spatial distribution, and habitat overlap. The crab-eating fox was more abundant than the pampas fox, occurring in all types of habitats and overlapping with the pampas fox only in the southern portion of the study area, covered by open vegetation. Both canid species presented nocturnal habits and C. thous showed no significant differences in activity among lunar phases or else year season. The density of C. thous was estimated to be 0.78 ind/km². The crab-eating fox reproduced once a year, generating pups during spring (October to December). In comparison with C. thous populations from lower-latitude regions the relatively low density and one reproductive event per year that we observed are probably related to a colder climate, shorter photoperiod, and shortage of food resources in the winter, characteristic of southern Brazil.
