Phylogenetic Tree of Cetacea and Artiodactyla

open access: yes, 2023
A phylogenetic tree generated using nucleotide sequences found on Ensembl, sequenced on NCBI BLAST, and inputted into PhyloT. Four species in the order Cetacea and five species in the order Artiodactyla were analyzed.

Zooarchaeology of Houses and Middens: Investigating Patterns of Assemblage Composition at Early Inuit Sites Across the North American Arctic

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT This study examines faunal assemblages from paired semisubterranean houses and middens at 10 Early Inuit sites spanning the North American Arctic (ca. 1200–1500 ce) to evaluate whether local resource bases or other factors primarily structure zooarchaeological variability.

Extrahepatic biliary tract pathologies in mammalian species of zoo animals and wildlife: a review

open access: yesJournal of Basic and Applied Zoology, 2020
Mammalian species express a broad variety in the shape of their extrahepatic biliary tract. While a gall bladder is present in many species, others are lacking this organ.

Cenozoic Tectonics Ignite Mitochondrial Codon Innovations Propelling Canid Body Size Evolution and Transcontinental Radiations

open access: yesIntegrative Zoology, EarlyView.
We decode mitochondrial genomes across all extant canids, revealing lineage‐specific codon optimization driven by altitude, predation, and body size. A tripartite framework integrates geological events, metabolic constraints, and adaptive radiation to explain carnivore evolution.

Why ruminating ungulates chew sloppily: Biomechanics discern a phylogenetic pattern.

open access: yesPLoS ONE, 2019
There is considerable debate regarding whether mandibular morphology in ungulates primarily reflects phylogenetic affinities or adaptation to specific diet.

Host Phylogeny and Feeding Habit Jointly Govern Mammalian Gut Microbiota Composition

open access: yesIntegrative Zoology, EarlyView.
Herbivores showed higher alpha diversity than carnivores/omnivores, while omnivores had the highest beta diversity. Host phylogeny influenced gut microbiota more strongly in herbivores/omnivores, with phylogenetic distance correlating to microbiota dissimilarity.

Humans are not unique: difficult birth is common in placental mammals

open access: yesBiological Reviews, Volume 101, Issue 5, Page 2214-2239, October 2026.
ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

Postcranial anatomy of the Miocene hippopotamoids of Toros‐Menalla, Chad

open access: yesJournal of Anatomy, Volume 249, Issue 4, Page 924-949, October 2026.
We establish a framework for the identification of postcranial remains in hippopotamoids by describing and comparing for the first time two late Miocene hippopotamoids from Toros‐Menalla, Chad (Hexaprotodon garyam, an early hippopotamid, and Libycosaurus bahri, the last African anthracothere) with the common hippopotamus.

An Updated Checklist of Terrestrial Mammals of Hainan Island, China

open access: yesBiological Diversity, Volume 3, Issue 3, Page 180-189, September 2026.
Building upon the foundational work Birds and Mammals of Hainan Island (1983), and synthesizing verified species records accumulated over the past four decades under a modern taxonomic framework, we present an updated checklist documenting 95 species of terrestrial mammals on Hainan Island.
