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 …

Different blood parasites can co‐infect natural populations of lizards. However, our
knowledge of the host's ability to recover from them (ie, significantly reduce parasitemia …

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 …

Multiple within individual and non-redundant signals can convey complementary information
about individual quality in lizards. This visual information is commonly provided by colour …

Elaborate sexual signals are thought to have evolved and be maintained to serve as honest
indicators of signaller quality. One measure of quality is health, which can be affected by …

The severity of parasitic infections can mediate the differential expression of signals among
populations, creating variation in signal intensity. Male signals (patch size and brightness) …

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 …
