Individual differences in growth and size of vertebrates often represent adaptive, plastic
responses to contrasts in ecological conditions. Recent studies show that vertebrates can …

Research on sociality in marine fishes is a vibrant field that is providing new insights into
social evolution more generally. Here, we review the past two decades of research …

Individuals that forgo their own reproduction in animal societies represent an evolutionary
paradox because it is not immediately apparent how natural selection can preserve the …

Parents play a key role in promoting the survival of their offspring, yet care is often given at
the expense of other activities. Therefore, the optimal parenting strategy can shift depending …

Wild populations are continuously challenged by natural environmental variation as well as
threatened by anthropogenically-induced habitat loss and fragmentation. Non-genetic …

Animal societies in which some individuals forgo their own reproduction and help others to
reproduce are one of the most remarkable products of evolution. The evolution of animal …

Female investment in reproduction is a critical component of life history that influences both
the fitness of the female and her offspring. Oviparous females can allocate energy into egg …

Understanding variation in social organization that lacks a strong phylogenetic signal
represents a key focus of research in behavioural ecology. Accordingly, we established a …

Understanding drivers of species co-existence on coral reefs is important to predict
community responses to environmental change. Here, we present, for the first time …

The susceptibility of species to habitat changes depends on which ecological drivers shape
individual fitness components. To date, only a few studies have quantified fitness …
