Divergence Across Niche Dimensions Reveals Species' Ecological Roles. [PDF]

open access: yesEcol Lett
Natural history gaps hinder our understanding of species' ecological roles and their contributions to ecosystem processes. Using an integrative framework, we analysed multiple niche dimensions of co‐occurring xenarthran insectivores, revealing divergent trophic, spatial and temporal patterns that reflect distinct ecological roles. Our results challenge

Collared Peccary Wallows are Hubs of Animal Activity and Diversity in a Central American Wet Forest. [PDF]

open access: yesEcol Evol
Collared 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]

open access: yesActa 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

Geologically calibrated mammalian tree and its correlation with global events, including the emergence of humans

open access: yesEcology 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

open access: yesJournal 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

open access: yesEcology, 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 ...

Roadkill patterns in Latin American birds and mammals

open access: yesGlobal Ecology and Biogeography, Volume 31, Issue 9, Page 1756-1783, September 2022., 2022
Abstract Aim Roads are a major threat for wildlife, degrading habitat and causing mortality via wildlife–vehicle collisions. In Latin America, the conjunction of high biodiversity and a rapidly expanding road network is reason for concern. We introduce an approach that combines species traits and habitat preferences to describe vulnerability and map ...

Guanaco colonisation of Tierra del Fuego Island from mainland Patagonia: Walked, swam, or by canoe?

open access: yesGeo: Geography and Environment, Volume 9, Issue 2, July‐December 2022., 2022
A geographical and biological puzzle that has perplexed scientists since the late 1800s working in southern South America: why are there so few vertebrates on the island of Tierra del Fuego compared to the adjacent Patagonia mainland, including the absence of the ubiquitous Guanaco (Lama guanicoe), wild camelid of the south? An interdisciplinary search
