Ultraestrutura e expressão das enzimas: citocromo P450 aromatase e citocromo P450c17 (17-α-hidroxilase/17,20-liase) nas diferentes fases do desenvolvimento da via espermática e espermatogênese em cutia (Dasyprocta sp.) criada em cativeiro [PDF]
, 2015 Espécies silvestres com grande potencial zootécnico devem ser exploradas de forma racional a fim de se evitar a extinção das mesmas. Assim se dá a importância de pesquisas voltadas à reprodução daquelas criadas em cativeiro, como a cutia (Dasyprocta sp.).

Testing the quick meal hypothesis: the effect of pulp on hoarding and seed predation of Hymenaea courbaril by red-rumped agoutis (Dasyprocta leporina) [PDF]
, 2006 Red-rumped agoutis (Dasyprocta leporina) are important seed dispersers/predators of Neotropical large-seeded plants. Several species of seeds cached by agoutis have an edible reward, in contrast to temperate rodent-dispersed diaspores.

Anthropogenic disturbances simplify frugivory interactions in Amazonia
Oikos, Volume 2025, Issue 7, July 2025.Frugivory interactions are essential ecological processes for the regeneration of tropical forests, ensuring ecosystem resilience following disturbances. However, little is known about how frugivory interactions are shaped by anthropogenic disturbances, especially in Amazonia – one of the most biodiverse ecosystems on Earth.

MICROBIOTA INTESTINAL EM CUTIAS CRIADAS EM CATIVEIRO
Ciência Animal Brasileira, 2009 Os intestinos são colonizados por microorganismos, variáveis de acordo com a espécie e região intestinal. Assim, em virtude da ausência de informações sobre esse assunto na literatura, esta pesquisa foi desenvolvida para melhor se conhecer alguns ...

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.

People and Nature, Volume 7, Issue 4, Page 871-886, April 2025.Abstract Rural communities in Amazonia rely on harvesting Mauritia flexuosa fruit, a dominant peatland palm, for their subsistence and income. However, these palms are felled to harvest the fruits, which has led to reduced resource availability due to the pressure exerted by the increasing fruit demand.

Ecology, Volume 106, Issue 3, March 2025.Abstract Tropical forests are disappearing, but we have a limited understanding of the factors driving species coexistence in mammal communities of old‐growth forest ecosystems. The total energy that is bound by plants is assumed to be a key factor determining mammalian species richness, but accurately measuring energy flows in complex ecosystems is ...
