TL;DR: Time courses obtained by targeted qPCR revealed that ‘blooms’ in specific bacterial groups occurred rapidly after a dietary change, and these were rapidly reversed by the subsequent diet.

TL;DR: It is shown that elevated testosterone enhanced ornamentation and increased circulating antioxidant levels, but caused oxidative damage, which explained the impacts of testosterone and parasites on ornamentation within treatment groups.

TL;DR: It is shown that ornamentation is ultimately a product of the cumulative physiological response to environmental challenges, and this findings lead toward a more realistic concept of honesty in signaling as well as a broader discussion of the concept of stress.

TL;DR: It is shown that parasites increase stress and reduce carotenoid‐based coloration, and that the impact of parasites on coloration was associated with changes in corticosterone, more than changes in body mass.

TL;DR: Interactions between parasites, oxidative stress and the carotenoid-based ornamentation of red grouse Lagopus lagopus scoticus are explored, and experimental results suggest that oxidative stress can mediate the impact of parasites on carotanoid- based signals.
