Asexuals are an important test case for theories of why species exist. If asexual clades
displayed the same pattern of discrete variation as sexual clades, this would challenge the …

Longevity is a major determinant of individual differences in Darwinian fitness. Several studies
have analyzed the stochastic, time‐dependent causes of variation in longevity, but little …

Bdelloid rotifers are aquatic microinvertebrates common in water bodies and in unstable “terrestrial”
habitats, such as mosses and lichens. The key to the adaptability to live in unstable …

In response to drought bdelloid and monogonont rotifers undergo anhydrobiosis and are
assumed to synthesize protective chemicals, which are commonly sugars. In contrast to most …

Background Normal and pathological processes entail the production of oxidative substances
that can damage biological molecules and harm physiological functions. Organisms have …

Background In diverse taxa, photoperiodic responses that cause seasonal physiological and
behavioural shifts are controlled by genes, including the vertebrate Clock orthologues, that …

We investigated sex‐ and year‐dependent variation in the temporal and spatial movement
pattern of barn swallows Hirundo rustica during the non‐breeding period. Hundred and three …

Life of many organisms flows as a sequence of annual cycles. Timing of cyclical events is
shaped by natural selection also via the domino effects that any life history stage has on the …

Dissecting phenotypic variance in life history traits into its genetic and environmental
components is at the focus of evolutionary studies and of pivotal importance to identify the …

The Chernobyl nuclear accident produced the largest unintended release of radionuclides in
history, with dramatic consequences for humans and other organisms. Exposure to ionizing …
