It was hypothesized that climate change had reduced the availability of the penguins' preferred zooplankton prey, so that the Campbell population's decline was caused by its unusual reliance on a fish-based diet which resulted in low body masses and demographic rates. I examined this hypothesis ...

Barriers can impede the movement of fishes between areas critical to the completion of their lifecycle, affecting both population and ecosystem viability. In response, fish passage solutions have been identified as a critical need to maintain fisheries viability in the Laurentian Great Lakes, and ...
Edmondson's egg ratio (number of amictic eggs per female) is an important life history variable, which has been in wide use to understand and predict patterns of population growth in planktonic rotifers under field conditions. It is also useful as an indicator of the health of rotifers under...
The fish farming industry has been more focused on the quality of eggs or larvae rather than that of sperm, even though the quality of both gametes may affect fertilisation success and larval survival. In some species, poor sperm quality can be a limiting factor in their culture, however, ev...
wageneri have been reported by several authors to infect fish in the Gulf of Mexico [35, 51, 86], none of these authors provided data on the prevalence or mean abundance of this parasite for other zones in the Gulf of Mexico. Thus, it is difficult to know if the high values of the...
