Artificial nests as an alternative to studies of arboreal small mammal populations: a five-year study in the Atlantic Forest, Brazil

Zoologia (Curitiba), 2011
Despite the great diversity of Brazilian Atlantic forest small mammals, natural history of most species is unknown due to their cryptic and nocturnal habits, but also due to the inadequacy of methods to capture some species, especially those of arboreal ...

Statistical support for the hypothesis of developmental constraint in marsupial skull evolution. [PDF]

, 2013
Background: In contrast to placental neonates, in which all cranial bones are ossified, marsupial young have only the bones of the oral region and the exoccipital ossified at birth, in order to facilitate suckling at an early stage of development.

MORPHOMETRICS OF THE GENUS DIDELPHIS (DIDELPHIMORPHIA: DIDELPHIDAE) IN VENEZUELA [PDF]

Journal of Mammalogy, 2002
We review systematics of genus Didelphis in Venezuela by craniometrical analyses of 93 skulls from adult D. albiventris pernigra, D. a. imperfecta, and D. marsupialis. Adults were sexually invariant for most characters, although males were, in general, larger than females. Complementary morphometric data obtained from literature on D.

Avian influenza overview June–September 2025

EFSA Journal, Volume 23, Issue 10, October 2025.
Abstract Between 7 June and 5 September 2025, 183 highly pathogenic avian influenza (HPAI) A(H5) virus detections were reported in domestic (27) and wild (156) birds across 15 countries in Europe. Although HPAI A(H5N1) virus detections were predominant in western and southwestern Europe, they also occurred on the northernmost coast of Norway. More than

Network dynamics revealed from eDNA highlight seasonal variation in urban mammal communities

Journal of Animal Ecology, Volume 94, Issue 8, Page 1587-1602, August 2025.
Our novel study applied eDNA to track seasonal shifts in urban mammal communities, revealing changes in diversity and species interaction networks across 21 urban parks in Detroit. We highlight the influence of park size and human activity on biodiversity, demonstrating the utility of eDNA for urban conservation and wildlife management.

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.
