Roadkill patterns in Latin American birds and mammals
Global 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 ...

Ecology and Evolution, Volume 11, Issue 14, Page 9447-9459, July 2021., 2021 Incisors of fossil and extant Geomyidae (pocket gophers) and Heteromyidae (pocket mice, spiny pocket mice, kangaroo mice, kangaroo rats) show enamel with built‐in failure prevention related to chisel‐tooth digging. This distinctive microstructure character strengthens the joint phylogenetic origin of these North American rodents because it is absent in

Ecology and Evolution, Volume 11, Issue 11, Page 7080-7092, June 2021., 2021 We used geometric morphometric data to asses whether fluctuating asymmetry (FA) on mandibles of Neotropical water rats (Nectomys squamipes) from eight sites within Brazilian Atlantic forest remnants would be related to habitat amount, genetic diversity, and/or inbreeding on individual and populational level.

Comparative karyology in Akodon (Rodentia, Sigmodontinae) from southeastern Brazil [PDF]
Journal of Heredity, 1998 Karyotypic comparisons among five Akodon species showed that they shared a substantial proportion of their chromosome complements, indicated by distinct homologies between chromosomes, arms, or arm regions despite that this genus is karyotypically rearranged.

Ancient DNA preserved in small bone fragments from the P.W. Lund collection
Ecology and Evolution, Volume 11, Issue 5, Page 2064-2071, March 2021., 2021 The Lund collection is one of the oldest fossil collections in the world, but it is not known whether the poorly preserved small mammal bones that constitute the majority of the collection are suitable for ancient DNA analysis. We genetically identify 17 species, representing 11 mammals, two birds, one fish, and three frogs from small fragmentary bones
