Lead exposure in Laysan albatross adults and chicks in Hawaii: prevalence, risk factors, and biochemical effects.
Prevalence of lead exposure and elevated tissue lead was determined in Laysan albatross (Diomedea immutabilis) in Hawaii. The relationship between lead exposure and proximity to buildings, between elevated blood lead and droopwing status, and elevated liver lead and presence of lead-containing paint chips in the proventriculus in albatross chicks was also examined. Finally, the effects of lead ...
متن کاملSuccessful same-sex pairing in Laysan albatross.
Unrelated same-sex individuals pairing together and cooperating to raise offspring over many years is a rare occurrence in the animal kingdom. Cooperative breeding, in which animals help raise offspring that are not their own, is often attributed to kin selection when individuals are related, or altruism when individuals are unrelated. Here we document long-term pairing of unrelated female Lays...
متن کاملOrgan Growth and Oxygen Consumption in Laysan Albatross Embryos
AasraAcr.-Embryonic oxygen consumption and organ growth were measured in the Laysan Albatross (Diomedea immutabilis). The logarithms of oxygen consumption and organ mass increased linearly with the logarithm of whole-embryo wet mass. The rate of growth of skeletal muscle and the gastro-intestinal tract exceeded that of the embryo as a whole, while the heart, lungs, brain, and eyes grew more slo...
متن کاملNecrotizing enteritis as a cause of mortality in Laysan albatross, Diomedea immutabilis, chicks on Midway Atoll, Hawaii.
A necropsy survey of Laysan albatross, Diomedea immutabilis, chicks on Midway Atoll in June 1993, 1994, and 1995 revealed 54% (21/39), 67% (49/71), and 93% (15/16), respectively, to have enteritis as the most severe pathologic finding. The lesion was limited to the ileum, ceca, and large intestine. We were unable to attribute a single infectious etiology to this lesion. Many birds with enteriti...
متن کاملAdaptive value of same-sex pairing in Laysan albatross.
Same-sex pairing is widespread among animals but is difficult to explain in an evolutionary context because it does not result in reproduction, and thus same-sex behaviour often is viewed as maladaptive. Here, we compare survival, fecundity and transition probabilities of female Laysan albatross in different pair types, and we show how female-female pairing could be an adaptive alternative mati...
