Root-feeding beetles, particularly of the curculionid subfamilies Scolytinae and Molytinae, are known to be effective vectors of Ophiostomatoid fungi. Infestation by these insects and subsequent infection by the Ophiostomatoid fungi may play an important role in accelerating symptom progression in pine declines. To examine the relationship between beetles and fungi in longleaf pine stands, root...

The diet and feeding methods of kakapo (Strigops habroptilus) on Stewart Island, southern New Zealand, were studied by examining sign left by the birds. Most feeding sign was found on herbs, ferns, and shrubs, especially on new and developing growth such as leaves, bark, fruits and seeds, as well as the subterranean portions. The species on which most kakapo sign was found were Lycopodium ramul...

A study was initiated at the Savannah River Site, New Ellenton, SC, to determine factors involved in decline of longleaf pine associated with prescribed burning. Pretreatment and post-treatment surveys were conducted on all treatment plots. Symptomatic trees were recorded by means of a crown rating system based upon symptom severity. Three years after prescribed burning treatments were initiate...

Abstract Ponds and wetlands around the world face anthropogenic pressures that threaten key ecosystem processes such as nutrient organic matter cycling. Wetlands in arid semi-arid regions are particularly at risk from uncertainty of water availability competing for use. Such threats most acute non-perennial systems rely on occasional surface flows to maintain important ecological functions. Thi...
