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

open access: yesBiological 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.

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade

open access: yesBiological Reviews, Volume 101, Issue 4, Page 1760-1778, August 2026.
ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

Keratan Sulfate: An Electroconductive Glycosaminoglycan at the Interface of Sensory Perception and Neural Signaling

open access: yesJournal of Neuroscience Research, Volume 104, Issue 8, August 2026.
Laboratory studies show KS has electroconductive properties with the ability to trap and transport protons in neurotransductive processes (Grotthuss proton shuttling). This maintains electrochemical gradients and fluxes at the neuronal cell surface in neural activation. Such processes are central to neuronal cell signaling and communication.

“Being Nice” as Modus Vivendi in Classrooms: A Collective Behavior Approach to Deviant Behavior in Primary Schools

open access: yesSymbolic Interaction, Volume 49, Issue 3, Page 663-685, August 2026.
This study of first‐year primary school draws on Goffman's concept of “collective behavior” to examine how order is established and disrupted through the mutual adjustment of all participants' actions. We employed a multi‐method longitudinal design, using semi‐standardized observations and qualitative interviews with teachers and children at three ...

Ecology of reintroduced Rocky Mountain bighorn sheep in Dinosaur National Monument La Ecología de Borrego Cimarron de las Montañas Rocosas Reintroducido en el Monumento Nacional de Dinosaurio

open access: yesWildlife Monographs, Volume 223, Issue 1, August 2026.
We synthesized GPS telemetry, genetic, and pathogen data to evaluate metapopulation processes in a reintroduced Rocky Mountain bighorn sheep (Ovis canadensis canadensis) population in Dinosaur National Monument. We estimated subpopulation‐specific abundances and found 4 small subpopulations with high genetic diversity, partial connectivity, and ...

Intraspecific variability in feather moult extent declines under both low and high constraints

open access: yesFunctional Ecology, Volume 40, Issue 8, Page 2350-2362, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Intraspecific trait variability (ITV) is a fundamental feature of biological populations and the raw material upon which natural selection acts, yet its drivers remain poorly understood.
