Patterns of interspecific variation in labial microarchitecture among anthropoid primates and the evolution of the hominin lips

open access: yesThe Anatomical Record, EarlyView.
Comparative histological and semi‐automated image analysis of primate lips: Masson's trichrome‐stained sagittal sections were segmented to quantify the connective tissue, adipose, and muscular components, enabling interspecific comparisons of labial architecture.

Comparative morphometric analysis of the proximal femur of African hominids and felids

open access: yesSouth African Journal of Science, 2015
Size and shape of the mammalian proximal femur and taxon-specific distinctions in the relative proportions of the proximal articulation, the femoral neck and the proximal femoral diaphysis, are critical determinants in its adaptation to differential ...

Taxon, Arboreality, Sex, and Season—Factors Influencing Gastrointestinal Parasite Occurrence in Zoo‐Housed Non‐Human Primates

open access: yesZoo Biology, EarlyView.
ABSTRACT The emergence of anthelminthic resistance is a well‐documented phenomenon in livestock and companion animals. Given the scarcity of new antiparasitic drugs, the implementation of effective, holistic anthelminthic control strategies is critical to preserving the efficacy of existing treatments.

The raphe nuclear organization and serotonergic system in the bat (Artibeus planirostris)

open access: yesJournal of Anatomy, EarlyView.
Schematic representation of the methodological workflow used to characterize the serotonergic (5‐HT) system in the bat Artibeus planirostris. Serotonin (5‐HT) immunohistochemistry was performed on brainstem sections to identify and map the distribution of serotonergic neurons within the raphe nuclei.

A conditional compression distance that unveils insights of the genomic evolution

open access: yes, 2014
We describe a compression-based distance for genomic sequences. Instead of using the usual conjoint information content, as in the classical Normalized Compression Distance (NCD), it uses the conditional information content.

Citizen science reveals host‐switching in louse flies and keds (Diptera: Hippoboscidae) during a period of anthropogenic change

open access: yesMedical and Veterinary Entomology, EarlyView.
A study of louse flies in the United Kingdom, Isle of Man, and Ireland found 212 different interactions between Hippoboscidae and their hosts, of which 70 were previously unrecorded. No louse flies were found on aquatic species of birds. Host‐switching to gulls (Laridae) has occurred during a period in which these species have started relying on ...

Earliest evidence of caries lesion in hominids reveal sugar-rich diet for a Middle Miocene dryopithecine from Europe. [PDF]

open access: yesPLoS ONE, 2018
The formation of dental caries is mainly caused by dietary habits and therefore, may contain information for dietary reconstructions of fossil hominids.
