Using Drones for Large Mammal Monitoring

Mammal Review, Volume 56, Issue 3, September 2026.
Drones were used to obtain video data on animals and locations and distance from the midline was automatically determined by our pipeline so that the input for Distance sampling is generated. ABSTRACT Introduction The emergence of drones has profoundly transformed the field of large mammal monitoring, offering unprecedented capabilities for data ...

Meat Acquisition Skill and Male Reproductive Success in Guinea Baboons

American Journal of Biological Anthropology, Volume 190, Issue 4, August 2026.
ABSTRACT Objectives In human foraging societies, hunting skill is often interpreted as a signal of male quality linked to reproductive success through his ability to provision his family and community. Similarly, in some bird and insect species, males offer mates food to indicate their quality as a provider.

Functional Differences in Muscle Architecture Across the Pelvis and Hind Limb of Primates

American Journal of Biological Anthropology, Volume 190, Issue 4, August 2026.
ABSTRACT Objectives Understanding the architectural diversity of primate musculature is essential for interpreting locomotor function and reconstructing evolutionary adaptations. This study examines whether interspecific differences in pelvic and hind limb muscle architecture reflect functional differentiation among major muscle groups.

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.
