Mechanical injury is a prevalent challenge in the lives of animals with myriad potential consequences for organisms, including reduced fitness and death. Research on animal injury has focused on many aspects, including the frequency and severity of wounding in wild populations, the short- and long-term consequences of injury at different biological scales, and the variation in the response to injury within or among individuals, species, ontogenies, and environmental contexts. However, relevant research is scattered across diverse biological subdisciplines, and the study of the effects of injury has lacked synthesis and coherence.

- The study examines the toxicity of fine particulate matter (PM2.5) in Atlanta using freshwater rotifers as test organisms.
- PM samples were extracted in water and methanol, and their toxic effects were measured in terms of LC50, indicating that ambient particles can kill between 50% of the rotifers at concentrations of 5 to 400 μg of PM.
- Methanol extracts of the aerosols proved to be significantly more toxic (8 ± 6 times) to the rotifers than water extracts, and over 70% of the observed toxicity was linked to the hydrophobic fraction of PM, suggesting complex interactions among different PM components.
