Physiological mechanisms mediating costs of immune responses: what can we learn from studies of birds?
D Hasselquist, JÅ Nilsson - Animal Behaviour, 2012 - Elsevier
Activating the immune system has associated fitness costs, both immediate costs in the form
of reduced current reproduction and long-term costs in the form of reduced life span and …

Ultraviolet signals ultra-aggression in a lizard
Understanding the role of multiple colour signals during sexual signalling is a central theme
in animal communication. We quantified the role of multiple colour signals (including …

Pigment-based skin colour in the blue-footed booby: an honest signal of current condition used by females to adjust reproductive investment
In monogamous species, the value of present reproduction is affected by the current
condition of the mate, and females may use male ornaments to evaluate his condition and …

Parental and Mating Effort: Is There Necessarily a Trade‐Off? (Invited Review)
One of the common assumptions in the study of the evolution of parental care is that trade‐
offs exist between parental investment and other fitness‐related traits. In general, this body …

Red fish, blue fish: trade-offs between pigmentation and immunity in Betta splendens
Carotenoid pigments are responsible for many examples of sexually attractive red, orange,
and yellow coloration in animals and play an important role in antioxidant and immune …

The hidden ageing costs of sperm competition
Ageing and sexual selection are intimately linked. There is by now compelling evidence
from studies performed across diverse organisms that males allocating resources to mating …

Testosterone coordinates gene expression across different tissues to produce carotenoid-based red ornamentation
Carotenoid pigments underlie most of the red, orange, and yellow visual signals used in
mate choice in vertebrates. However, many of the underlying processes surrounding the …

The energetics of immunity
The oft-cited quote by Dhabzhansky above reflects the importance of applying an
evolutionary approach to the study of biological questions. Although this almost certainly …

Dietary amino acids influence plumage traits and immune responses of male house sparrows, Passer domesticus, but not as expected
Traits that influence social interactions (signals) are widely thought to be honest indicators of
some underlying quality of their bearer. One hypothesis is that a signal and the bearer's …
