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

Biological Reviews, EarlyView.
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 ...

Maternal glucocorticoids have persistent effects on offspring social phenotype irrespective of opportunity for social buffering

Journal of Animal Ecology, EarlyView.
This study tests whether early‐life maternal association buffers offspring from the effects of prenatal stress in a facultatively social lizard. Despite clear effects of maternal glucocorticoids on growth and social behaviour, social associations did not mitigate these effects, revealing limits to social buffering in this species.

Induced Pluripotent Stem Cells with Six Reprogramming Factors from Prairie Vole, Which is an Animal Model for Social Behaviors

Cell Transplantation, 2016
Prairie voles show strong pair bonding with their mating partners, and they demonstrate parental behavior toward their infants, indicating that the prairie vole is a unique animal model for analysis of molecular mechanisms of social behavior.

Individual characteristics, experience, and environmental conditions shape large‐scale patterns of animal activity timing

Ecosphere, Volume 17, Issue 6, June 2026.
Abstract The timing of an animal's activity affects its survival and reproduction because timing determines the nature of every interaction an organism has with its environment. Although the timing of activity may depend on aspects of the individual (e.g., body mass, reproductive status, experience) or the nature of the environment (e.g., temperature ...

Nonapeptide molecular evolution during the adaptive radiation of Tanganyika cichlids

Journal of Neuroendocrinology, Volume 38, Issue 6, June 2026.
Abstract Oxytocin (OT) and vasotocin (VT) are evolutionarily conserved nonapeptides that regulate a wide range of physiological and behavioral processes in vertebrates. Their receptor families have undergone gene duplications that facilitated functional diversification throughout vertebrate evolution.

Mapping the cellular basis of species differences in oxytocin and dopamine receptor expression in the vole nucleus accumbens

Scientific Reports
Oxytocin (Oxtr) and dopamine (Drd1, Drd2) receptors provide a canonical example for how differences in neuromodulatory receptors drive individual and species-level behavioral variation. These systems exhibit striking and functionally relevant differences

Does water vole diet meet the prerequisites of the “plant hypothesis” for explaining population cycles?

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Rodent population cycles are observed in highly seasonal environments. As most rodents are herbivorous, the availability and the quality of their food resources vary greatly across seasons. Furthermore, it is well documented that herbivore densities have a measurable effect on vegetation and, conversely, that vegetation dynamics can influence ...

Natural variation in planting‐year climate explains variation in developing floristic composition of restored prairie

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.
This study demonstrates planting‐year climate can predict the cover of frequently occurring species and major compositional groups in prairie developing from seed. Our results advance understanding of factors contributing to variable restoration outcomes, which is needed to achieve conservation goals.

The macroecology of immunity: predominant influence of climate on invertebrate immune response

Ecography, Volume 2026, Issue 4, April 2026.
The immune system is the primary defense against parasites. With the ever‐increasing rate of disease, epidemiologic models considering geographic variation in immune responses could prove useful. Despite increasing interest in the macroecology of parasitism and infectious diseases, we know little about the macroecology of immune responses (i.e ...

Sex differences in neuromodulatory subcortical systems and their implications for Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 3, March 2026.
Abstract Neuromodulatory subcortical systems (NSSs) are uniquely susceptible to dementia‐related pathology, leading to frequent molecular and behavioral impairments associated with altered function of these nuclei. Some of these systems display clear sex‐specific cytoarchitecture and signaling leading to distinct physiology and behavioral outputs in ...
