Early mortality and perinatal growth in the subantarctic fur seal (Arctocephalus tropicalis) on Amsterdam Island
Early mortality and pup growth during the perinatal period were investigated in pups of the subantarctic fur seal Arctocephalus tropicalis on Amsterdam Island. Mothers that were shorter in body length and expected to be younger, gave birth earlier in the pupping season, compared with longer/older mothers. Pups born early were often still-born, suggesting that shorter/younger mothers that gave b...

An infectious agent with a male-predilection is the most plausible explanation for this di...
