13. Frequency of leucism in a colony of Anoura geoffroyi (Chiroptera: Phyllostomidae) roosting in a ferruginous cave in Brazil
Resumo: Relatamos aqui o primeiro registro de frequência de leucismo em uma espécie de morcego Neotropical. Leucismo é uma anomalia na pigmentação da pele dos animais que consiste na perda total ou parcial da cor natural da espécie, podendo acometer partes ou todo o corpo do animal. Em um estudo de captura e marcação de indivíduos de uma população

14. Litter Size Reduction Induces Metabolic and Histological Adjustments in Dams throughout Lactation with Early Effects on Offspring
In the present study we analyzed morphological and metabolic alterations in dams nursing small litters and their consequences to offspring throughout lactation. Offspring sizes were adjusted to Small Litter (SL, 3 pups/ dam) and Normal Litter (NL, 9 pups/ dam). Body weight, food intake, white adipose tissue (WAT) content, histological analysis of the pancrea

15. Predation of an American fruit-eating bat (Artibeus sp.) by an Amazon tree boa (Corallus hortulanus) in the northern Brazilian Amazon
RESUMO Nós relatamos uma observação de predação por uma serpente Corallus hortulanus sobre um morcego do gênero Artibeus em uma área de floresta estacional perto de um córrego, no norte da Amazônia brasileira. Enquanto os morcegos parecem ser um dos principais itens alimentares de C. hortulanus, a nossa observação representa somente o quarto relat

16. Methods of biological maceration in the preparation of bat skulls: benefits and limitations
Abstract Osteologic collections are used as an aid to scientific and teaching activities, to provide information on specific vertebrate characteristics, such as body support, posture, mode of locomotion, feeding habits and ecological niche. Known techniques for cleaning entire skeletons or mammalian skulls vary according to the destination of the material, t

17. Does frugivory in Citharexylum solanaceum (Verbenaceae) drive nomadism in the Ipanema bat Pygoderma bilabiatum (Chiroptera: Phyllostomidae)?
ABSTRACT Neotropical bats are recognized as effective seed dispersers, especially of small-seeded pioneer plants during early stages of forest regeneration. There had been few reports on the ecology of the bat Pygoderma bilabiatum (Wagner, 1843), which appears to be mainly frugivorous and to undertake vertical migrations in Brazil. Our analyzes of fecal samp

18. Activity patterns of frugivorous phyllostomid bats in an urban fragment in southwest Amazonia, Brazil
ABSTRACT: The habitat fragmentation modifies the pattern of animal activity. This study aimed to determine the activity pattern of frugivorous bat species in an urban forest fragment in southwestern Amazonia. The study was conducted from August 2013 to September 2014 with 10 mist nets (9m x 2.5m), opened at ground level throughout all the night and totaling

19. Single nucleotide polymorphisms of cytokine-related genes and association with clinical outcome in a Chagas disease case-control study from Brazil
BACKGROUND The severity of chronic chagasic cardiomyopathy (CCC), the most frequent clinical outcome of Chagas disease (CD), has been associated with cytokine-enriched heart tissue inflammation, and high serum levels of transforming growth factor (TGFβ), interferon-gamma (IFNγ), and tumour necrosis factor (TNF). Conversely, increased interleukin (IL)-10 s

20. Neonatal tobacco smoke reduces thermogenesis capacity in brown adipose tissue in adult rats
Maternal smoking is a risk factor for progeny obesity. We have previously shown, in a rat model of neonatal tobacco smoke exposure, a mild increase in food intake and a considerable increase in visceral adiposity in the adult offspring. Males also had secondary hyperthyroidism, while females had only higher T4. Since brown adipose tissue (BAT) hypofunction i

21. Range extension to Santo Domingo de los Tsáchilas province and revised distribution of Platyrrhinus chocoensis (Phyllostomidae: Chiroptera) in western Ecuador
Abstract We report the first record of the Choco broad-nosed bat (Plathyrrhinus chocoensis Alberico & Velazco, 1991) in Santo Domingo de los Tsáchilas province in northwestern Ecuador. This voucher specimen represents the southernmost record of the species and expands its distribution ca. 120 km south. The animal was caught at a farm, specifically in a live

22. Life-long Maternal Cafeteria Diet Promotes Tissue-Specific Morphological Changes in Male Offspring Adult Rats
ABSTRACT Here, we evaluated whether the exposure of rats to a cafeteria diet pre- and/or post-weaning, alters histological characteristics in the White Adipose Tissue (WAT), Brown Adipose Tissue (BAT), and liver of adult male offspring. Female Wistar rats were divided into Control (CTL; fed on standard rodent chow) and Cafeteria (CAF; fed with the cafeteria

23. Morphology of the axial skeleton of seven bat genera (Chiroptera: Phyllostomidae)
ABSTRACT Here we present detailed descriptions and comparisons of the axial skeleton of seven species of bats belonging to five subfamilies of Phyllostomidae of different trophic guilds. The material examined consisted of 34 complete skeletons of seven species. For five of the studied species, previous descriptions have not been conducted, and for the vampir

24. Differences between caves with and without bats in a Brazilian karst habitat
ABSTRACT. Since bats shelter in roosts during their period of diurnal inactivity, the quality and availability of roosts are important aspects of their ecology. Karst areas have great potential for the availability of day roosts, since they form caves, which serve as bat shelters. Here we characterize the caves used by bats in a preserved karst area of South
