Zoologica Scripta, EarlyView.ABSTRACT Micoureus is the most species‐rich subgenus within the genus Marmosa. Conflicting arrangements regarding the number of species comprising this subgenus have been proposed and the validity of M. budini has been debated. Here, we used an approach integrating genetic and morphological data were conducted to reanalyze the ‘rapposa’ group ...

Marine Mammal Science, Volume 42, Issue 3, July 2026.ABSTRACT The presence of the franciscana (Pontoporia blainvillei) at the northern limit of the FMA II was investigated using a range of methods, including monitoring of strandings, boat surveys, and passive acoustic monitoring (PAM). Franciscana strandings were recorded within the distributional gap between Macaé (22°55′ S) and Ilha Grande (23°09′ S ...

Las áreas de mitosis forjan nuevos estilos en los estudios sobre paleontología de mamíferos
Estudios Geologicos, 2006 Desde el siglo XIX, la morfología descriptiva y comparada de los molares, basada en la observación directa y comparación morfológica, es utilizada para elegir los caracteres, que mejor fundamenta la filogenia de los linajes de mamíferos.

Marine Mammal Science, Volume 42, Issue 3, July 2026.ABSTRACT The American manatee (Trichechus manatus) requires freshwater mainly from rivers and springs to maintain osmoregulatory balance in saline environments. However, in Brazil's semi‐arid Potiguar Basin, manatees now rely solely on submarine freshwater springs because hypersaline estuaries have become unsuitable sources of freshwater.

Functional divergence drives the prevalence of low‐abundance species in bat assemblages
Functional Ecology, Volume 40, Issue 6, Page 1587-1602, June 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological communities are structured by a few common species, while most occur at low abundance. Understanding the drivers of this widespread pattern raises fundamental questions about community assembly rules and is important for applied ecology for identifying ...

Austral Ecology, Volume 51, Issue 6, June 2026.ABSTRACT Understanding animal distribution is crucial for elucidating natural history, population dynamics, and inter‐ and intraspecific interactions. This knowledge informs the planning and evaluation of management and conservation strategies, particularly for sympatric, scarce, and threatened species such as jaguars (Panthera onca) and pumas (Puma ...
