First record of complete albinism in Carollia perspicillata (Chiroptera; Phyllostomidae)

FALCÃO, F.C. 2014. First record of complete albinism in Carollia perspicillata (Chiroptera; Phyllostomidae). Chiroptera Neotropical 20(1):1234-1236.

Abstract. Albinism is a phenomenon present in many vertebrate species, and can be defined as the absence of normal pigmentation of an organism. In bats, complete albinism is considered a rare phenomenon, and its occurrence was recorded for less than 4% of all existing bat species. On 6 September 2012, an individual of Carollia perspicillata (Linnaeus, 1758) was captured in Igaporã, Bahia, and it had all characteristics of complete albinism, lacking normal pigmentation over the entire body surface, including the iris. The purpose of this paper is to report the first record of complete albinism in Carollia perspicillata and thereby increase the number of species recorded with such anomalies; in addition to contributing to the understanding of this pigmentation disorder.

Coexistence of jaguar (Panthera onca) and puma (Puma concolor) in a mosaic landscape in the Venezuelan llanos

SCOGNAMILLO, D.; MAXIT, I.E.; SUNQUIST, M.; POLISAR, J. 2003. Coexistence of jaguar (Panthera onca) and puma (Puma concolor) in a mosaic landscape in the Venezuelan llanos. Journal of Zoology, London 259:269-279.

Abstract. Jaguar Panthera onca and puma Puma concolor are sympatric throughout the jaguar’s distribution. Although several studies have focused on the interactions between these two predators, the ecological and behavioural factors that promote their coexistence remain unclear. The goal of this study was to identify those factors that facilitate the coexistence of these cats in a mosaic landscape in the Venezuelan llanos. The study was conducted from January 1996 until November 1998. Five jaguars and six pumas were captured and radio-collared. A high degree of spatial overlap was observed between jaguars and pumas, which may be related to the abundance and distribution of prey species. At a fine scale, there was little overlap of puma locations with jaguar locations. Both species were more active at night than during daytime, but seasonal differences were detected in the activity levels of these predators. Major segregation was found in food habits. Jaguars selected for large prey and pumas for medium-sized prey. Jaguars selected for capybara Hydrochaeris hydrochaeris and collared peccary Tayassu tajacu and consumed caiman Caiman crocodilus and white-tailed deer Odocoileus virginianus less than expected. Pumas selected just for collared peccary and also killed caiman less than expected. It is suggested that the abundance of medium-sized prey is an ecological factor that is facilitating the coexistence of jaguar and puma in the study area. Habitat heterogeneity may be another influential factor leading to the coexistence. Seasonal differences in activity levels probably reflect differences in the size and species of prey taken by these cats.

Diet of margay, Leopardus wiedii, and jaguarundi, Puma yagouaroundi, (Carnivora: Felidae) in Atlantic Rainforest, Brazil

BIANCHI, R.C.; ROSA, A.F.; GATTI, A.; MENDES, S.L. 2011. Diet of margay, Leopardus wiedii, and jaguarundi, Puma yagouaroundi, (Carnivora: Felidae) in Atlantic Rainforest, Brazil. Zoologia 28(1):127-132. doi: 10.1590/S1984-46702011000100018.

Abstract. This study identifies the food habits of the margay, Leopardus wiedii (Schinz, 1821), and the jaguarundi, Puma yagouaroundi (É. Geoffroy Saint-Hilare, 1803), in the Vale do Rio Doce Natural Reserve and in the Sooretama Biological Reserve, Espírito Santo, Brazil. We determined the diet of both species by the analysis of scats. Fecal samples were collected from April 1995 to September 2000 and identified based on the presence of hairs that were ingested during self-grooming. Scats were oven-dried and washed on a sieve, and the screened material was identified using a reference collection. Of the 59 fecal samples examined, 30 were confirmed to be from the margay and nine of them from the jaguarundi. Mammals were the most consumed items in the diet of the margay, occurring in 77% of the fecal samples, followed by birds (53%) and reptiles (20%). Among the mammals consumed, marsupials (Didelphimorphia) were the most common item (66%). In the diet of the jaguarundi, birds were the most consumed items and occurred in 55% of the fecal samples; mammals and reptiles occurred in 41% and in 17% of the fecal samples, respectively. From this work we conclude that the margay and jaguarundi fed mainly upon small vertebrates in the Vale do Rio Doce Natural Reserve and in the Sooretama Biological Reserve. Although sample sizes are therefore insufficient for quantitative comparisons, margays prey more frequently upon arboricolous mammals than jaguarundis, which in turn prey more frequently upon birds and reptiles than margays. This seems to reflect a larger pattern throughout their geographic range.

First record of leucism in Artibeus phaeotis (Miller, 1902) (Chiroptera: Phyllostomidae) from Guatemala

TRUJILLO, L.A.; BARAHONA, R. 2014. First record of leucism in Artibeus phaeotis (Miller, 1902) (Chiroptera: Phyllostomidae) from Guatemala. Chiroptera Neotropical 20(1):1252-1254.

Abstract. The aim of this communication is to report the first documented case of leucism in Artibeus phaeotis from Guatemala. The bat was captured in Laguna del Tigre National Park, Petén, in northern Guatemala, while we were conducting a bat sampling in the area. Leucism is a condition rarely observed in nature, which is characterized by the partial or total depigmentation of fur; in this case the specimen is distinguished by a depigmentation in the ventral side of the body.
