The handicap hypothesis of sexual selection predicts that sexual ornaments have evolved
heightened condition–dependent expression. The prediction has only recently been subject …

Over the past decade, there has been a substantial increase in interest in the immune
system and the role it plays in the regulation of disease susceptibility, giving rise to the field …

The past 30 years of immunological research have revealed much about the proximate
mechanisms of maternal antibody transmission and utilization, but have not adequately …

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 …

Although reproductive strategies can be influenced by a variety of intrinsic and extrinsic
factors, life history theory provides a rigorous framework for explaining variation in …

Understanding the mechanisms that link ornamental displays and individual condition is key
to understanding the evolution and function of ornaments. Immune function is an aspect of …

We used the stalk‐eyed fly Cyrtodiopsis dalmanni to examine predictions made by condition‐
dependent handicap models of sexual selection. Condition was experimentally varied by …

Mechanisms maintaining honesty of sexual signals are far from resolved, limiting our
understanding of sexual selection and potential important parts of physiology. Carotenoid …

Early nutrition has recently been shown to have pervasive, downstream effects on adult life–
history parameters including lifespan, but the underlying mechanisms remain poorly …

In egg-laying animals, mothers can influence the development of their offspring via the suite
of biochemicals they incorporate into the nourishing yolk (eg lipids, hormones). However …
