occur when the conceptus enters a state of suspended animation at the blastocyst stage of …

The reproductive biology of seals is fascinating in many aspects. As in most mammals, the
time of onset of puberty in seals is variable. Once sexually mature, most but not all seals are …

Reproductive failure in mammals due to exposure to polychlorinated biphenyls (PCBs) can
occur either through endocrine disrupting effects or via immunosuppression and increased …

Pup mortality and the timing of birth of South American sea lions Otaria flavescens were
investigated to determine the possible relationship between fluctuations in prey availability …

Population-level shifts in reproductive phenology in response to environmental change are
common, but whether individual-level responses are modified by demographic and genetic …

Understanding how female body condition (FBC) influences foetal development, and hence
offspring production, is fundamental for our understanding of species reproductive …

We examined the seasonality of reproduction in captive and wild bottlenose dolphins,
Tursiops truncatus. Stranding records of neonatal dolphins and observed births from a long …

We examined the reproductive performance of female Steller sea lions (Eumetopias jubatus)
in order to evaluate the hypothesis that low pup production was associated with nutritional …

The study tested the hypothesis that the occurrence of pregnancy in mammals that are
capital breeders will be most closely related to state variables that are indices of food stores …

1. This study examined the costs of reproduction in terms of future survival and reproduction
in female Antarctic fur seals from Bird Island, South Georgia. It used mark-recapture data …
