Collared Peccary Wallows are Hubs of Animal Activity and Diversity in a Central American Wet Forest. [PDF]
Ecol EvolCollared peccary wallows are used by a diverse assemblage of vertebrates in a Central American tropical wet forest. Wallows had significantly higher vertebrate activity and diversity compared to surrounding forest. Wallow visitors included 13 amphibian, 2 reptile, 11 bird, and 16 mammal species, engaged in behaviors including reproduction, drinking ...

Diversity of cingulate xenarthrans in the middle-late Eocene of Northwestern Argentina [PDF]
Acta Palaeontologica Polonica, 2016 The study of Paleogene mammals of intermediate and low latitudes has increased in the last decades and has been clearly demonstrated their importance in the comprehension of the evolution and faunistic changes outside Patagonia. The study of these faunas

Morphofunctional Space of the Forelimb in Caraguatypotherium munozi (Notoungulata; Mesotheriidae): Insights Into Wrist-Powered Digging. [PDF]
J MorpholCaraguatypotherium munozi displays a distinctive morphofunctional configuration combining high wrist flexor leverage with reduced elbow mechanical advantage—traits consistent with wrist‐dominated scratch‐digging. Multivariate analyses place it outside the core morphospaces of extant locomotor groups.

Ecology and Evolution, Volume 13, Issue 12, December 2023., 2023 A robust minimum age tree shows post K–Pg Placentalia radiation, and subsequent extensive radiation connected to exponentially increased base substitution (mutation) rate including generation of Homo sapiens. This Neogene radiation may have been triggered by expansion of C4 grasses that decreased atmospheric CO2, resulting in global cooling and ...

Fleas and lesions in armadillo osteoderms
Journal of Anatomy, Volume 242, Issue 6, Page 1029-1036, June 2023., 2023 Study of lesions caused by flea's ‘bites’ in the bones on the backs of armadillos show that they are actually made by the host's own osteoclasts, not by the flea's own masticatory apparatus. Panels (a, c, e) are reconstructions from high‐contrast resolution X‐Ray Microtomography and (b, d, f) backscattered electron mode scanning electron microscopy ...

Spatiotemporal distributions of mammals occurring in an agro‐prairie ecosystem
Ecology, Volume 104, Issue 3, March 2023., 2023 Abstract Anthropogenic activities since the European colonization of the North American Great Plains have drastically altered landscape composition and configuration, subsequently affecting native biodiversity. These contemporary human‐modified landscapes may affect mammal species' distributions, diel activity patterns, habitat use, and interspecific ...
