Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

open access: yesIntegrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Overexpression of MAP2 and NF-H Associated with Dendritic Pathology in the Spinal Cord of Mice Infected with Rabies Virus

open access: yesViruses, 2018
Rabies is a viral infection that targets the nervous system, specifically neurons. The clinical manifestations of the disease are dramatic and their outcome fatal; paradoxically, conventional histopathological descriptions reveal only subtle changes in ...

Unravelling the phylogeny of armadillos and their kin (Mammalia, Xenarthra, Cingulata) combining morphological, molecular, and stratigraphic data

open access: yesCladistics, EarlyView.
Abstract Cingulata, a major lineage of Xenarthra, comprises extinct and extant armoured placental mammals that diversified throughout the Cenozoic. Despite extensive study, phylogenetic hypotheses based on morphological and molecular data remain incongruent, and no total evidence analysis has been conducted. Here, we integrate the largest morphological

Revisiting avian wingtip shape indices: a comparison of methods with empirical data

open access: yesIbis, EarlyView.
The study of avian wing shape helps in understanding how birds can adapt to their habitats and respond to changing environmental conditions. An important challenge in this endeavour is obtaining estimates of wing shape that are truly independent of body size, particularly when there is an allometric relationship between them. Size‐constrained component

Ecology and morphology as drivers of passerine song differentiation across an island archipelago

open access: yesIbis, EarlyView.
We conducted an integrative analysis to explore possible explanations for the song differentiation in bird populations from the mainland and the Tres Marías Archipelago (TMA) on the central‐western Pacific coast of Mexico. We first analysed the effect of isolation on cultural transmission by comparing repertoire size and genetic fixation in four ...
