Polymyxins: wisdom does not always come with age.

The polymyxins have become last-line treatments for patients with MDR bacterial infections. An increasing body of published literature has attempted to answer questions about dosing, pharmacology, and susceptibility testing of these drugs, yet each takes for granted purit...

Is recruitment related to spawning stock in penaeid shrimp fisheries?

The relationship between spawning stock and recruitment in penaeid shrimp fisheries has been questioned because they exhibit unique characteristics with respect to population dynamics and fisheries. This study used meta-analyses to test the null hypothesis that recruitment is a series of random, independent events based on the penaeid shrimp stocks found in published sources. Both the derivativ...

Monitoring does not always count.

The gross under-resourcing of conservation endeavours has placed an increasing emphasis on spending accountability. Increased accountability has led to monitoring forming a central element of conservation programs. Although there is little doubt that information obtained from monitoring can improve management of biodiversity, the cost (in time and/or money) of gaining this knowledge is rarely c...

An explicit solution for calculating optimum spawning stock size from Ricker’s stock recruitment model

Stock-recruitment models have been used for decades in fisheries management as a means of formalizing the expected number of offspring that recruit to a fishery based on the number of parents. In particular, Ricker's stock recruitment model is widely used due to its flexibility and ease with which the parameters can be estimated. After model fitting, the spawning stock size that produces the ma...
