Amidst global shifts in the distribution and abundance of wildlife and livestock, we have only a rudimentary understanding of ungulate parasite communities and parasite-sharing patterns. We used qPCR and DNA metabarcoding of fecal samples to characterize gastrointestinal nematode (Strongylida) community composition and sharing among 17 sympatric species of wild and domestic large mammalian herbivore in central Kenya. We tested a suite of hypothesis-driven predictions about the role of host traits and phylogenetic relatedness in describing parasite infections. Host species identity explained 27 – 53% of individual variation in parasite prevalence, richness, community composition and phylogenetic diversity. Host and parasite phylogenies …


The Naming Of Homo Bodoensis By Roksandic And Colleagues Does Not Resolve Issues Surrounding Middle Pleistocene Human Evolution, Eric Delson, Chris Stringer Jan 2022

The Naming Of Homo Bodoensis By Roksandic And Colleagues Does Not Resolve Issues Surrounding Middle Pleistocene Human Evolution, Eric Delson, Chris Stringer

Publications and Research

Roksandic et al. (2022) proposed the new species name Homo bodoensis as a replacement name for Homo rhodesiensis Woodward, 1921, because they felt it was poorly and variably defined and was linked to sociopolitical baggage. However, the International Code of Zoological Nomenclature includes regulations on how and when such name changes are allowed, and Roksandic et al.'s arguments meet none of these requirements. It is not permitted to change a name solely because of variable (or erroneous) later use once it has been originally defined correctly, nor can a name be modified because it is offensive to one or more …


Pore Extractor 2d: An Imagej Toolkit For Quantifying Cortical Pore Morphometry On Histological Bone Images, With Application To Intraskeletal And Regional Patterning, Mary E. Cole, Sam D. Stout, Victoria M. Dominguez, Amanda M. Agnew Jan 2022

Pore Extractor 2d: An Imagej Toolkit For Quantifying Cortical Pore Morphometry On Histological Bone Images, With Application To Intraskeletal And Regional Patterning, Mary E. Cole, Sam D. Stout, Victoria M. Dominguez, Amanda M. Agnew

Publications and Research

Objectives: Cortical porosity is used as a proxy of bone quality, fragility, and remo- deling activity in anthropological contexts. Histological quantification is limited by time-intensive manual annotation. Pore Extractor 2D is an ImageJ toolkit developed for computer-assisted pore identification and automated pore morphometry. Materials and Methods: Toolkit components include: (1) Utilities for cortical border clearing, (2) Image Pre-Processing: Image contrast enhancement and noise reduction, (3) Pore Extractor: User-directed options for segmenting, closing, and smoothing pore spaces, (4) Pore Modifier: Utilities to expedite manual correction of extracted pore spaces, and (5) Pore Analyzer: Morphometric analyses by pore type and anatomical region. …
