Timber harvesting has been shown to have both positive and negative effects on forest dwelling species. We examined the immediate effects of timber harvests (clearcuts and group selection openings) on ectotherm behavior, using the eastern box turtle as a model. We monitored the movement and thermal ecology of 50 adult box turtles using radiotelemetry from May-October for two years prior to, and...

The point of departure for this paper is the familiar prototype fisheries model where a fictitious sole owner harvests a fish population to maximize present discounted profits. The paper answers analytically the following question. “What happens to a policy when the sole owner also values biodiversity, as well as profits?” It turns out that the size of the steady-state stock and the number of s...

Pine straw harvesting con provide on economic benefit to landowners, but the practice may also change the composition of plant communities. This research was initiated in o 34-yeor-old stand of longleaf pine (Pinus palustris Mill.} established in 1956 to study how pine straw management practices (fertilization, prescribed fire, and straw harvesting) affected plant communities, and herein, effec...

This paper analyses yeast diversity and dynamics during the production of Asturian cider. Yeasts were isolated from apple juice and at different stages of fermentation in a cellar in Villaviciosa during two Asturian cider-apple harvests. The species identified by ITS-RFLP corresponded to Hanseniaspora valbyensis, Hanseniaspora uvarum, Metschnikowia pulcherrima, Pichia guilliermondii, Candida pa...
