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.

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 ...

Vivid biofluorescence discovered in the nocturnal Springhare (Pedetidae)

Scientific Reports, 2021
Biofluorescence has been detected in several nocturnal-crepuscular organisms from invertebrates to birds and mammals. Biofluorescence in mammals has been detected across the phylogeny, including the monotreme duck-billed platypus (Ornithorhyncus anatinus)

Marked decline in forest-dependent small mammals following habitat loss and fragmentation in an Amazonian deforestation frontier [PDF]

, 2020
Agricultural frontier expansion into the Amazon over the last four decades has created million hectares of fragmented forests. While many species undergo local extinctions within remaining forest patches, this may be compensated by native species from ...

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.

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.

Skin development in the gray short‐tailed opossum (Monodelphis domestica)—From skin respiration to thermoregulation

Journal of Anatomy, Volume 247, Issue 1, Page 108-133, July 2025.
The skin development in the gray short‐tailed opossum (Monodelphis domestica) has been examined using histological, morphometric, and μCT methods. During a long period of postnatal development, the structural differentiation of the skin results in a functional shift from transcutaneous gas exchange to thermoregulation in later life. Abstract Marsupials
