Late Quaternary population expansion in gray brocket deer [Subulo gouazoubira (G. Fisher, 1814), Cervidae, Mammalia] in Brazil

Journal of Quaternary Science, Volume 40, Issue 6, Page 1031-1042, August 2025.
ABSTRACT There is little information about the changes in the abundance of mammalian species in South America during the late Quaternary, which is a key parameter to understanding past ecological and evolutionary dynamics. Here, we describe a conspicuous increase in the abundance of the gray brocket deer (Subulo gouazoubira G.

Avaliação de dois métodos para condicionamento e coleta de sêmen em quatro espécies do gênero Mazama

Pesquisa Veterinária Brasileira, 2012
O desenvolvimento de técnicas não invasivas para a obtenção de sêmen de cervídeos facilita a criação de bancos genômicos, que são importantes instrumentos para a conservação ex situ e in situ.

Do precipitation and food affect the reproduction of brown brocket deer Mazama gouazoubira (G. Fischer 1814) in conditions of semi-captivity?

Anais da Academia Brasileira de Ciências, 2010
The births of brown brocket deer ( Mazama gouazoubira) in a secondary lower montane forest called "yunga" in northwestern Argentina were compared with rainfall.

Área de vida do veado-catingueiro (mazama gouazoubira; Fisher, 1814) no Pantanal da Nhecolândia-MS. [PDF]

, 2013
O gênero é Mazama possui dez espécies reconhecidas, sendo o mais diverso entre os cervídeos neotropicais. As características ecológicas deste grupo, adaptado para ambientes florestais fechados, constituem a principal razão pela qual a história natural do

Relationship between moonlight and nightly activity patterns of the ocelot (Leopardus pardalis) and some of its prey species in Formosa, Northern Argentina [PDF]

, 2016
The moon can profoundly influence the activity patterns of animals. If predators are more successful under bright moonlight, prey species are likely to respond by shifting their own activity patterns (predator-avoidance hypothesis).

Surviving in the Amazon Arc of Deforestation: Richness and Defaunation of Mammals in Priority‐Protected Areas of the Brazilian Midwest

Austral Ecology, Volume 50, Issue 7, July 2025.
We found rich and compositionally different assemblages of medium and large‐sized mammals in protected areas on the southern edge of Amazon. However, both have high rates of mammal defaunation. We argue that anthropogenic threats in the Amazon Arc of Deforestation are eroding large ungulate populations, especially peccaries.

Diversity and Activity Pattern of Terrestrial Mammal Species in Serra do Amolar, Brazilian Pantanal 巴西潘塔纳尔湿地阿莫拉尔山脉陆生哺乳动物物种的多样性及活动模式

Wildlife Letters, Volume 3, Issue 2, Page 56-63, June 2025.
The Serra do Amolar, located in the Brazilian Pantanal, is a crucial but understudied area for biodiversity conservation. Through camera traps, we recorded 29 mammal species, including three rodent species documented for the first time in the area: Cavia aperea, Cuniculus paca, and Holochilus chacarius.

TESTE DE TUBERCULINIZAÇÃO EM VEADO CATINGUEIRO MAZAMA GOUAZOUBIRA FISHER, 1814 (ARTIODACTYLA: CERVIDAE) [PDF]

Arquivos do Instituto Biológico, 2009
RESUMO A tuberculose bovina é uma doença infectocontagiosa, causada pelo Mycobacterium bovis, que também pode ocorrer em outros hospedeiros mamíferos. Foram analisados 4 cervídeos adultos (Mazama gouazoubira) três fêmeas e 1 um macho de um criatório conservacionista da região do Alto Paranaíba, Goiás, Brasil.

Plant and frugivore species characteristics drive frugivore contributions to seed dispersal effectiveness in a hyperdiverse community

Functional Ecology, Volume 39, Issue 1, Page 238-253, January 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Seed dispersal by frugivores is a crucial step of the life cycle of most plants, influencing plant population and community dynamics. Although very important for most ecosystems, we are just beginning to understand which are the mechanisms driving frugivore‐mediated ...
