Biological delineation of terrestrial buffer zones for pond-breeding salamanders
Article Abstract:
Biodiversity of vanishing wetlands depends on protecting areas around the wetlands. US federal and state regulations protect only wetlands or arbitrarily defined portions of terrestrial habitat, or none at all, although many semi-aquatic organisms, among them salamanders, depend on terrestrial areas. For one group of pond-breeding salamanders, data indicate adult salamanders were found a mean distance of 125.3 m from the edge of aquatic habitats. A buffer zone encompassing 95% of the population should be established 164.3 m from the edge of a wetland.

Prioritizing Pacific salmon stocks for conservation: response to Allendorf et al
Article Abstract:
Uncomplicated, objective criteria have been put forward for classification of risk and for prioritizing conservation projects for Pacific salmon, but full evaluation of risks was not carried out. Criteria should include biological factors important in definition of risk to salmon. Definitions of risk levels should be more consistent across criteria. Proposed reliance on formal, model-based population viability analysis (PVA) should be emphasized less. Careful evaluation of empirical factors involved in risk should be carried out.

Effects of a biological control introduction on three nontarget native species of Saturniid moths
Article Abstract:
Research indicates that the introduction of Compsilura concinnata, a parasitoid fly from the Diptera family, may be accountable for the declines in silk moth populations reported in New England. C. concinnata was introduced as a biological control against other insect pests, but has shown a significant impact on nontarget species such as Callosamia promethea and the threatened silk moth species Hemileuca maia maia.
