For decades, we have observed a major biodiversity crisis impacting all taxa. Avian species
have been particularly well monitored over the long term, documenting their declines. In …

According to recent empirical studies, reproductive senescence, the decline in reproductive
success with increasing age, seems to be nearly ubiquitous in the wild. However, a clear …

Williams' evolutionary theory of senescence based on antagonistic pleiotropy has become a
landmark in evolutionary biology, and more recently in biogerontology and evolutionary …

Correctly assessing the total impact of predators on prey population growth rates (lambda, λ)
is critical to comprehending the importance of predators in species conservation and wildlife …

The trade-off between offspring size and number is central to life history strategies. Both the
evolutionary gain of parental care or more favorable habitats for offspring development are …

Urban areas represent a spectrum that goes from being safe habitats for biodiversity (ie,
habitats more or equally preferred, without costs to fitness) to being ecological traps (ie …

In most animals, body mass varies with ecological conditions and is expected to reflect how
much energy can be allocated to reproduction and survival. Because the sexes often differ in …

Offspring size is a key functional trait that can affect all phases of the life history, from birth to
reproduction, and is common to all the Metazoa. Despite its ubiquity, reviews of this trait tend …

Predators affect the survival of develo** young by eating them. More recently, the fear of
being eaten has been uncovered as a powerful driver of offspring survival reducing recruited …

Successfully establishing captive breeding programs is a priority across diverse industries to
address food security, demand for ethical laboratory research animals, and prevent …
