Interactions between maternal provisioning and natural selection on seed mass fluctuate across heat waves

American Journal of Botany, EarlyView.
Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

Mating suppresses sperm-dependent male avoidance in C. elegans hermaphrodites.

PLoS ONE
In many sexually reproducing animals, females incur higher reproductive costs and therefore tend to be more selective in accepting mates. In Caenorhabditis elegans, self-fertilizing hermaphrodites produce a limited number of self-sperm, and previous ...

Per‐ and Polyfluoroalkyl Substances (PFAS) Exposure Profiles and Their Predictors in a Study of US Volunteer Firefighters

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Introduction Firefighters may experience occupational exposure to per‐ and polyfluoroalkyl substances (PFAS). Volunteer firefighters make up 65% of the US fire service, but their serum PFAS profiles have not been well characterized. This study aims to (1) describe PFAS serum profiles among US volunteer firefighters from 9 states enrolled in ...
