Carotenoid ornaments and the spandrels of physiology: a critique of theory to explain condition dependency
Even as numerous studies have documented that the red and yellow coloration resulting
from the deposition of carotenoids serves as an honest signal of condition, the evolution of …

Do sexual differences in life strategies make male lizards more susceptible to parasite infection?
Female and male hosts may maximise their fitness by evolving different strategies to
compensate for the costs of parasite infections. The resulting sexual dimorphism might be …

Urbanisation impacts the diversity, coloration, and body size of wild bees in a Mediterranean city
Urbanisation is a growing phenomenon causing the decline of wild bees globally. However,
bees manage to persist in the urban environment thanks to islands of vegetation in public …
