Interest in individual differences in animal behavioural plasticities has surged in recent
years, but research in this area has been hampered by semantic confusion as different …

Why do the two sexes have different lifespans and rates of aging? Two hypotheses based
on asymmetric inheritance of sex chromosomes (“unguarded X”) or mitochondrial genomes …

Life-history strategies are diverse. While understanding this diversity is a fundamental aim of
evolutionary biology and biodemography, life-history data for some traits—in particular, age …

Males and females in many species differ in how they age and how long they live. These
differences have motivated much research, concerning both their evolution and the …

Microplastic is a growing concern as an environmental contaminant as it is ubiquitous in our
ecosystems. Microplastics are present in terrestrial environments, yet the majority of studies …

Life-history theory assumes that traits compete for limited resources, resulting in trade-offs.
The most commonly manipulated resource in empirical studies is the quantity or quality of …

Sexual selection is considered the major driver for the evolution of sex differences. However,
the eco-evolutionary dynamics of sexual selection and their role for a population's adaptive …

Abstract Microplastics (MPs;< 5 mm) are a growing concern and a poorly understood threat
to biota. We used a generalist insect (a cricket; Gryllodes sigillatus) to examine whether …

The potential for sexual conflict to influence the evolution of life span and aging has been
recognized for more than a decade, and recent work also suggests that variation in life span …

Sexual conflict can promote the evolution of dramatic reproductive adaptations as well as
resistance to its potentially costly effects. Theory predicts that responses to sexual conflict …
