Clades, Grades, and the Genus Problem: A Case for Revising Hominin Taxonomy

American Journal of Biological Anthropology, Volume 190, Issue 4, August 2026.
ABSTRACT Taxonomic practice in evolutionary biology increasingly prioritizes the recognition of monophyletic groups (clades), yet paleoanthropology still applies this principle inconsistently. Here, I outline these inconsistencies and broader challenges in hominin taxonomy and propose a potential solution.

Placental crises: disruptive selection and maternal under‐investment as the foundations of mammalian placental evolution and dysfunction

Biological Reviews, Volume 101, Issue 4, Page 1627-1640, August 2026.
ABSTRACT Among the vertebrates, mammals are notable for the dominance of live birth and placental nutrition. The structural diversity of the mammalian placenta is remarkable, despite sharing a single common ancestor and conserved physiological functions.

Generation and characterization of two fibroblast-derived Baboon induced pluripotent stem cell lines

Stem Cell Research
Cross-species comparisons studying primate pluripotent stem cells and their derivatives are crucial to better understand the molecular and cellular mechanisms behind human disease and development.

Population dynamics of medium and large mammals in a West African gallery forest area and the potential effects of poaching

Journal of Threatened Taxa, 2017
Few studies are available on the population dynamics of medium and large mammals in gallery forests of the Sudan and Sahel regions of West Africa.  Line-transect studies of the abundance (estimated by KIA) of nine species of ungulates and three species ...

Impacts of habitats and seasons on mammalian diversity and distribution in the Faragosa-Fura landscape, Gamo Zone, Southern Ethiopia

Geology, Ecology, and Landscapes, 2021
In Ethiopia, most of the studies on mammals have focused on single species and protected areas. This survey investigated the impacts of habitats and seasons on the medium and large-sized mammals’ diversity and distribution in a human-dominated ...

Human‐Carnivore Conflicts and Associated Economic Losses in Villages Adjacent to Jorgo‐Wato Protected Forest, Western Ethiopia

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Conflicts between humans and carnivores were assessed in the nearby settlements of the Jorgo‐Wato Protected Forest. This aimed to identify carnivorous species responsible for livestock depredations, quantify the economic losses resulting from depredations, and identify strategies used by nearby communities to prevent human‐carnivore conflicts in the ...

Evolution of the antiretroviral restriction factor TRIMCyp in Old World primates. [PDF]

PLoS ONE, 2010
The retroviral restriction factor TRIMCyp, which is a fusion protein derived from the TRIM5 gene, blocks replication at a post-entry step. Among Old World primates, TRIMCyp has been found in four species of Asian macaques, but not in African monkeys.

Leukocyte profiles reveal sex and age differences in immune investment in a polygynous bat

Journal of Animal Ecology, Volume 95, Issue 8, Page 1453-1463, August 2026.
Analysis of over 500 blood cell profiles, including repeat samples over four years, reveals that male bats from a long‐lived species with a polygynous mating system invest more in innate than adaptive immunity. Investment in innate immunity increases with age, as estimated by a DNA methylation clock and mark‐recapture data.

Occurrence of Antibodies Anti‐Toxoplasma gondii in Captive Non‐Human Primates From Pernambuco State, Brazil

Journal of Medical Primatology, Volume 55, Issue 4, August 2026.
ABSTRACT Wildlife captive populations are important tools for threatened species conservation, and early identification of diseases must be prioritized. In this study, we test for the presence of anti‐Toxoplasma gondii antibodies in non‐human primates at a Zoo from Pernambuco State, Brazil.
