Fishers exploit populations that are heterogeneously distributed in space and time without full knowledge of species distributions and with fishing gear that is not fully selective. The ability to change catch composition is limited by species mix at a particular location and time and the capture characteristics of the fishing...
Discard rates in marine fisheries have been estimated at more than 80% for some individual fisheries, with an average global discard rate of 8%. Discarding of catch can be problematic for three main reasons: (1) in the absence of accurate and precise discards estimates, unreliable catch data distort estimation of...

Ascorbic acid, or vitamin C, is well known as a co-factor for proline-hydroxylase and as an anti-oxidant. However, it is also capable of forming covalent bonds, particularly in the role of a nucleophile, henceforth termed 'ascorbylation'.
The ascorbylation of electrophiles can occur under physiological conditions. Furthermore, there are a number...
Apart from the traditional role of preventing progression from HIV to AIDS, antiretroviral drug therapy (ART) has an additional benefit of substantially reducing infectiousness, making them potentially an important strategy in the fight against HIV. Recent advances in drug therapy have also seen the use of antiretroviral drugs as a...
During the summer of 1996, I had the opportunity to do an internship with the
Florida Keys National Marine Sanctuary (FKNMS) at Lower Key Office, Key West,
Florida. Established in November 1990 under the Florida Keys National Marine
Sanctuary and Protected Act, the FKNMS is a federal agency managed by...
Developing steelhead trout eggs and sac fry were examined for
wet, dry and lipid weights and for fatty acid composition over the
period from fertilization until the disappearance of the yolk sac, 69
days after fertilization. The yolk sac and embryo or fry were
separated shortly before hatching, and the...
The lessons learned from a review of thirteen bio-economic models are presented. We describe and analyze
how these models equal/ compare and differ in terms of the classification, their biological and economic
modules, the integration between modules, the indicators they provide and indicator use. We pay particular
attention to the...
