Life-history traits or “fitness components”—such as age and size at maturity, fecundity and
fertility, age-specific rates of survival, and life span—are the major phenotypic determinants …

Tolerance, or the maintenance of host health or fitness at a given parasite burden, has often
been studied in evolutionary and medical contexts, particularly with respect to effects on the …

Viruses are major evolutionary drivers of insect immune systems. Much of our knowledge of
insect immune responses derives from experimental infections using the fruit fly Drosophila …

Whether the character of developmental plasticity is adaptive or non-adaptive has often
been a matter of controversy. Although thermal developmental plasticity has been studied in …

We identified a 9332-nucleotide-long novel picornaviral genome sequence in the
transcriptome of an agriculturally important parasitoid wasp (Pachycrepoideus vindemmiae …

Sensory perception of environmental cues has been shown to trigger plastic responses that
can induce important fitness costs, including the dramatic modulation of aging across distant …

Males compete over mating and fertilization, and often harm females in the process.
Inclusive fitness theory predicts that increasing relatedness within groups of males may relax …

In general, males mate with multiple females to increase individual reproductive success.
Whether or not, and under what circumstances, females benefit from multiple mating has …

Intergenerational effects on offspring phenotypes occur in response to variation in both
maternal and paternal nutrition. Because the combined maternal and paternal effects are …

Sex differences in ageing and lifespan are ubiquitous in nature. The" unguarded-X”
hypothesis (UXh) suggests they may be partly due to the expression of recessive mutations …
