Human-modified landscapes have been threatening mammal populations worldwide. However, little is known about the genetic consequences of these impacts in long term for most species. Here, we analyzed the genetic diversity and population structuring of a top predator, the maned wolf (Chrysocyon brachyurus), to investigate genetic signatures that cou...

The hoary fox Lycalopex vetulus is the only wild canid endemic to Brazil, occurring mainly in open and mesic habitats of the Cerrado savanna and its ecotones. Here, we report the first photographic records of L. vetulus in a xeric habitat of a Caatinga dry forest–Cerrado savanna ecotone. We obtained four registers in the 2019 dry season through cam...

A brief communication in Brazilian virtual conference of the main result of hoary fox habitat selection research. We studied the space use of this vulnerable carnivore in an agroecosystem used for livestock production. We aligned foxes’ movement ecology with livestock management by searching for those habitats selected by foxes that also improve ca...

Animal coloring serves several functions, including camouflage and thermoregulation. However, some individuals have anomalous coloring patterns due to excess (melanism) or deficiency (albinism, leucism, or piebaldism) in melanin production. Although these anomalies occur in several species, there are few cited cases. Here, we report the occurrence...

Trypanosoma cruzi and Leishmania spp. are parasites that infect multiple hosts including canids, considered bioaccumulators of parasites. Deforestation in the Cerrado biome has resulted in the exposure of wild canids to anthropized areas, where they may establish ecological and epidemiological relationships with domestic dogs. We evaluated the infe...

The Hoary Fox, Lycalopex vetulus, is endemic to the Cerrado of Brazil, a savanna biome under severe anthropogenic pressure and with less than 20% of its original area undisturbed. The estimated number of mature individuals is 9,840-19,200 and it is estimated that the species has undergone a decline of 10% in the last ~12 years due to the joint effe...

Reproduction is key to species survival, and reproductive physiology represents a high priority investigative area for conservation biology, as it provides a basic understanding of critical life-history traits, information that is helpful for the establishment of management strategies. Here, we generated knowledge about the reproductive endocrinolo...

The persistent high deforestation rate and fragmentation of the Amazon forests are the main threats to their biodiversity. To anticipate and mitigate these threats, it is important to understand and predict how species respond to the rapidly changing landscape. The short-eared dog Atelocynus microtis is the only Amazon-endemic canid and one of the...

The increase of contact between natural and rural areas is prominent in Brazil, due to agricultural activities and concern with the environmental conservation. In this context, domestic animals, wild fauna and humans are exposed to mutual exchange of parasites, microorganisms and diseases. We studied tick parasitism of wild carnivores and domestic...

Studies on threatened species in highly modified and unprotected landscapes are necessary for the development of appropriate conservation policies.
