Phylogenetic Reconstruction of Lung Evolution in Extant Squamata

open access: yesJournal of Zoology, EarlyView.
The Squamata group exhibits remarkable diversity in lung structure. However, a comprehensive understanding of how this variation evolved within the clade is still lacking. To reconstruct the evolutionary history of lungs of living squamates, we conducted comparative phylogenetic analyses using categorized lung traits, such as lung type, respiratory ...

Ontogenetic Trophic Differentiation in the Amur Softshell Turtle (Pelodiscus maackii) From a Temperate Large‐River System

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
We investigated ontogenetic variation in diet composition of the Amur softshell turtle (Pelodiscus maackii) from a temperate large‐river system using stomach content analyses of field‐collected individuals. Dietary composition differed markedly across body‐size classes, indicating pronounced ontogenetic trophic differentiation and shifts in resource ...

Spatiotemporal Thermal Variation Modulates Phenotypic Plasticity in Freshwater Turtle Growth, Behavior, and Sex

open access: yesGlobal Change Biology Communications, Volume 1, Issue 3, September 2026.
Using a dataset that spans more than 50 years, we found that northern map turtles (Graptemys geographica) – an ectothermic species with temperature‐dependent sex determination – exhibited faster somatic growth rates, altered thermoregulatory behaviors, and a female‐biased sex ratio in recent years which were characterized by warmer, longer growing ...

Effects of off‐highway vehicle activity on Arizona wildlife: a systematic literature review

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 7, September 2026.
The published literature indicates that off‐highway vehicles (OHVs) predominantly negatively affect native Arizona amphibians, mammals, and reptiles, while effects of OHVs on native Arizona birds are mostly unknown or neutral. Abstract Off‐highway vehicle (OHV) recreation has dramatically increased in Arizona, USA, prompting concerns about potential ...
