Beyond maternal behavioral profiles: biparental care and individual behavioral variability in cooperatively breeding common marmosets (Callithrix jacchus)

Frontiers in Ecology and Evolution
While general maternal care behaviors such as carrying and nursing are well-documented in primates, recent research highlights significant inter-individual behavioral differences in offspring-directed actions.

Molecular methods for differentiating Phragmites australis subspecies and identification of hybrid stands in the Upper Midwestern United States

Applications in Plant Sciences, EarlyView.
Abstract Premise In North America, Phragmites australis (common reed) has drawn a great deal of research attention. Non‐native P. australis subsp. australis is a noxious weed that has locally displaced native P. australis subsp. americanus in some areas.

Variation in parental investment and relative clutch mass of the spiny-tail iguana, Ctenosaura pectinata (Squamata: Iguanidae) in central México Variación en la inversión parental y masa relativa de la nidada en la iguana de cola espinosa Ctenosaura pectinata (Squamata: Iguanidae) en el centro de México

Revista Mexicana de Biodiversidad, 2011
We measured the length, width, volume, and weight of 871 freshly laid eggs of 28 clutches of Ctenosaura pectinata. The iguanas were obtained from a tropical dry forest area in central Mexico. The relative clutch mass was related positively to the average

The “costly son” hypothesis: Sons exacerbate obstetrical dilemmas in humans and other mammals

The Anatomical Record, EarlyView.
Abstract Human childbirth has often been considered uniquely difficult among mammals, yet recent evidence suggests that obstructed labor and fetopelvic disproportion are widespread across placental mammals. Here, we propose the “costly son” hypothesis: because male offspring are typically larger at birth, they impose greater obstetric risk on mothers ...

Heat Stress in Quail: Impacts on Health and Productivity, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts physiological homeostasis in quail, inducing oxidative stress, immune dysregulation, and metabolic imbalance, which impair growth, reproduction, product quality, and welfare. Integrating nutritional, environmental, and genetic–epigenetic strategies enhances thermotolerance, sustains productivity, and supports climate‐smart quail ...
