BAZILIO, S.; BASTIANI, E.; GOLEC, C. 2015. New records and description of the microstructural patterns of guard hair in Conepatus chinga (Molina, 1782) (Carnivora, Skunk) for the states of Paraná and Santa Catarina, southern Brazil. Biotemas 28(1):79-84. doi: http://dx.doi.org/10.5007/2175-7925.2015v28n1p79
Abstract. This article aims to show new records of Conepatus chinga for the states of Paraná and Santa Catarina, in southern Brazil, contributing to increase knowledge on its distribution, besides describing the microstructural patterns of its guard hair. Three run-over specimens were found in highway BR-280, two of them in the town of Palmas, in Paraná, and one in the town of Abelardo Luz, in Santa Catarina. For describing the cuticular and medullary pattern of guard hairs, sixty slides were made. Conepatus chinga has a cross-sectional and undulated cuticular pattern and an anisocytic medullary pattern. The description of microstructural patterns of C. chinga makes it easier to conduct studies related to its ecology, increasing the chances to identify hairs found in fecal samples from carnivores in mastofauna studies.

O Journal
of Zoology publica artigos de pesquisa de alta qualidade que são originais
e são de amplo interesse. Os editores buscam estudos que sejam guiados por
hipóteses e de natureza interdisciplinar. Artigos sobre comportamento animal,
ecologia, fisiologia, anatomia, biologia do desenvolvimento, evolução,
sistemática, genética, e genômica serão considerados; pesquisas que explorem a
interface entre estas disciplinas são fortemente encorajadas. Estudos tratando
de tópicos geograficamente e/ou taxonomicamente restritos devem testar
hipóteses gerais, descrever novos achados ou ter amplas implicações.

Origin of the lumbosacral plexus in Galea spixii (Wagler, 1831) (Rodentia, Caviidae)
OLIVEIRA, G.B.; RODRIGUES, M.N.; SOUSA, R.S.; MOURA, C.E.B.; MIGLINO, M.A.; OLIVEIRA, M.F. 2014. Origin of the lumbosacral plexus in Galea spixii (Wagler, 1831) (Rodentia, Caviidae). Biotemas 27(4):107-115. http://dx.doi.org/10.5007/2175-7925.2014v27n4p107
Abstract. The yellow-toothed cavy is a rodent belonging to the Caviidae family that inhabits the semiarid region of northeastern Brazil. We used 20 cavies that had died of natural causes, obtained from the Reproduction Center of Wild Animals (CEMAS) of the Federal Rural University of the Semi-Arid (UFERSA). The animals were ixed in aqueous solution of 10% formaldehyde and, after 48 hours, they were dissected to visualize plexus. The topographic relations of the lumbosacral plexus were grouped into tables and then they underwent statistical analysis (chi-square test with Yates’ correction). The lumbosacral plexus stemmed from the ventral roots of the last 3 lumbar nerves and the irst 3 sacral nerves, corresponding to 65% of the animals under study (L5L6L7S1S2S3). These nerves stemmed from plexus: femoral, obturator, ischiatic, cranial gluteal, caudal gluteal, and pudendal.
Key words: Anatomy; Nerves; Nervous system; Rodent; Yellow-toothed cavy.

An opportunity for testing multiple paternity in a wild Jaguar (Panthera onca)
PINHO, G.M.; FONSECA, R.; FARIAS, I.P. 2014. An opportunity for testing multiple paternity in a wild Jaguar (Panthera onca). Biota Neotropica 14(3):1-5.
Abstract. We performed a paternity test for three cubs from one wild female jaguar (Panthera onca). The opportunity for this study was generated by an accident involving a vehicle collision with a pregnant jaguar in the central Amazon. The cubs are polyzygotic triplets and were found to have been sired by the same male. Here, we also provide an overview and discuss several aspects of jaguar reproduction.
