Mortality of sea lions along the central California coast linked to a toxic diatom bloom

Article Abstract:

It has been possible to produce the first conclusive evidence connecting sea lion deaths to a recorded harmful algal bloom. This research investigated the death of more than 400 California sea lions along the central California coast during May 1998 and Jun 1998. The trophic transfer of domoic acid resulting in marine mammal mortality was demonstrated. It seems that even a brief appearance of domoic acid in the food web has the potential to kill or cause illness among marine wildlife.

Disease susceptibility in California sea lions

Article Abstract:

Analysis of a group of rescued California sea lions reveals that inbred individuals tend to be more likely to be sick. Not only do they catch more diseases, but they serve as reservoirs for infectious agents among the healthy population, which has implications for zoo breeding programs.

The effect of ancient population bottlenecks on human phenotypic variation

Article Abstract:

The effects of the ancient population bottlenecks on the human phenotypic variation are being studied. The results reveal that the loss in genetic diversity starting from Africa is normally proportional to any loss in the phenotypic variability.
