Despite risks of infection and reduced fitness, tooth fracture frequency in gray wolves increases rapidly when prey are scarce because they must consume carcasses more completely.
After insemination, honeybee queens experience a rapid reduction in vision and flight performance, consistent with an ongoing sexual conflict over the number of mating flights that queens embark on.
Measurements of bar-headed geese flying in a wind tunnel in hypoxia reveal that these birds sustain aerobic flight at high altitude via a reduction in metabolism.
Single-cell analysis of the chloroplast redox response to high light and oxidative stress revealed light-dependent heterogeneity, and was linked to cell fate determination within isogenic diatom populations.
The fungal parasite Podosphaera plantaginis employs both sexual and asexual reproduction to increase its chances of infecting the plant Plantago lanceolata.
In natural pathogen populations opportunities for sexual outcrossing vary, leading to spatial variation in genetic diversity and between-season survival.
