Sexual intimidation is frequent in humans, but its evolutionary origin remain speculative because few animal studies have investigated comparable, long-term forms of sexual violence.

Costs of compensatory and accelerated growth in a hibernating mammal
Yellow-bellied marmots (Marmota flaviventer) live in highly seasonal environments and have limited time for development and fat accumulation. An increase in body mass is a strong determinant of overwinter survival, thus immature marmots (juveniles and yearlings) starting the active season with low body mass may exhibit compensatory growth. Additionally, adults may exhibit accelerated fat accumulation to compensate for (...)
