They may live in a habitat undergoing severe upheaval, or they may just lack the adaptability to keep pace, even if their environment is comparatively stable.
In that spirit, a team of European researchers examined records for 157 species of terrestrial mammals, looking for links between yearly weather anomalies, population growth rates, and species-level life history., point to a potentially important pattern in the relationship between a species's life history and its response to annual weather anomalies.
They can focus their energy on a smaller progeny, or sometimes just wait out lean times, the researchers note, unlike animals whose briefer lives offer less flexibility in the face of adversity. Indeed, these species often experience booms and busts, with populations sometimes surging or crashing depending on conditions., simply being more susceptible to extreme weather doesn't necessarily mean a species faces a higher extinction risk from climate change.
