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.

Diversity and Activity Pattern of Terrestrial Mammal Species in Serra do Amolar, Brazilian Pantanal 巴西潘塔纳尔湿地阿莫拉尔山脉陆生哺乳动物物种的多样性及活动模式

Wildlife Letters, Volume 3, Issue 2, Page 56-63, June 2025.
The Serra do Amolar, located in the Brazilian Pantanal, is a crucial but understudied area for biodiversity conservation. Through camera traps, we recorded 29 mammal species, including three rodent species documented for the first time in the area: Cavia aperea, Cuniculus paca, and Holochilus chacarius.

Mitigating Road Barrier Effects for Small Mammals: Evidence From Wildlife Passages in the Brazilian Atlantic Forest

Austral Ecology, Volume 50, Issue 6, June 2025.
Roads increase wildlife mortality and isolate populations. This study monitored the movements and abundance of small mammals in areas with and without wildlife passages along BR‐101 in Rio de Janeiro for 12 months. Our results show that although many mammals avoid roads, some species use these passages, increasing population connectivity.

From Hot to Cold Spots: Climate Change is Projected to Modify Diversity Patterns of Small Mammals in a Biodiversity Hotspot

Diversity and Distributions, Volume 31, Issue 5, May 2025.
ABSTRACT Aim Climate change represents one of the main threats to global biodiversity, and such alterations are expected to induce shifts in distribution ranges and diversity patterns. We evaluate if protected areas and forest remnants in the Atlantic Forest in South America (AF) are projected to ensure the taxonomic diversity (TD) and phylogenetic ...

Patterns of arboreal and terrestrial space use by non-volant small mammals in an Araucaria forest of southern Brazil

Anais da Academia Brasileira de Ciências, 2014
Despite the advances in the techniques for researching arboreal small mammals, detailed ecological data, such as habitat use patterns, are practically nonexistent for many species.

Functional anatomy of the wing muscles of the Egyptian fruit bat (Rousettus aegyptiacus) using dissection and diceCT

Journal of Anatomy, Volume 246, Issue 5, Page 685-695, May 2025.
Bats are unique among mammals for evolving powered flight. However, very little data are available on the muscle properties and architecture of bat flight muscles. Using diceCT and gross dissection, we show that the Egyptian fruit bat pectoralis is optimised for power, and the elbow flexion/extension group is optimised for high forces with large PCSA ...

Trypanosoma cruzi infection enhances olfactory response in Triatoma pallidipennis Stål (Hemiptera: Triatominae) to compounds potentially useful for insect control

Medical and Veterinary Entomology, Volume 39, Issue 1, Page 160-170, March 2025.
Triatoma pallidipennis is one of the main vectors of Trypanosoma cruzi, the causative agent of Chagas disease. Attractant activity of octenol, nonanal and a mixture of lactic acid, hexanoic acid and ammonium hydroxide on T. cruzi–infected and non‐infected T. pallidipennis nymphal stages.

EVOLUTION OF SCAPULA SIZE AND SHAPE IN DIDELPHID MARSUPIALS (DIDELPHIMORPHIA: DIDELPHIDAE) [PDF]

Evolution, 2009
The New World family Didelphidae, the basal lineage within marsupials, is commonly viewed as morphologically conservative, yet includes aquatic, terrestrial, scansorial, and arboreal species. Here, I quantitatively estimated the existing variability in size and shape of the Didelphidae scapula (1076 specimens from 56 species) using geometric ...
