Topografia do cone medular da paca (Agouti paca, Linnaeus - 1766)

Brazilian Journal of Veterinary Research and Animal Science, 2007
Objetivamos neste trabalho determinar a esqueletopia da terminação do cone medular da paca relacionando com as vértebras lombares e sacrais, visando assim estabelecer parâmetros morfométricos e topográficos do cone medular nesta espécie. Para tanto, procedemos à dissecação, mediante incisão, rebatimento da pele, da tela subcutânea e da musculatura da ...

Mammal defaunation leads to biotic homogenization of plant communities in tropical rainforests

Ecology, Volume 107, Issue 3, March 2026.
Abstract Biotic homogenization is the process in which species communities become increasingly similar across different regions over time. This phenomenon has substantial ecological, evolutionary, and economic implications, primarily driven by human activities such as habitat destruction, invasive species introduction, and climate change.

Animal–Plant Interactions Under Defaunation: Consequences for Amazonian Trees of Commercial Interest

Biotropica, Volume 58, Issue 2, March 2026.
We experimentally investigated the effects of medium‐ and large‐sized mammal defaunation on the removal and fate of seeds from economically important forest species in Amazonian forests. Our results show that mammal exclusion significantly reduced seed removal, although the magnitude of this effect varied among plant species.

Fallen Logs Act as Natural Bridges Over Rivers in a Tropical Wet Forest

Biotropica, Volume 58, Issue 1, January 2026.
We studied how vertebrate species used logs as bridges over rivers in a tropical rainforest. Most mammals present in the area used logs, but the frequency and probability of crossing varied widely among species, between seasons, and in relation to the dimensions of the log and the river below.
