MOTIVATION The prediction of ligand-binding residues or catalytically active residues of a protein may give important hints that can guide further genetic or biochemical studies. Existing sequence-based prediction methods mostly rank residue positions by evolutionary conservation calculated from a multiple sequence alignment of homologs. A problem hampering(More)
Impacts of habitat edges on wildlife populations have received considerable attention, yet few researchers have quantified changes in animal community structure on both sides of an interface between distinct habitats. To gain a better understanding of the ways in which species-specific responses scale up to produce community patterns across habitat(More)
An integrated modeling system was developed to predict runoff losses of pesticides from agricultural lands. The system is an integration of a mathematical model, a database system, and a geographic information system. Information on soil type, land use, land slope, watershed boundaries, precipitation, pesticide usage, as well as physical and chemical(More)
Understanding how invasive plants affect biodiversity is a crucial conservation need. Numerous studies examine impacts of invasions on birds, but trends in these effects have not been synthesized. We reviewed 128 studies from North America to quantify the frequency of positive, negative, and neutral (non-significant) effects of invasive plants on avian(More)
Ptilochronology, the study of feather growth bars, has been used to assess nutritional condition, yet the implementation of this technique can be challenging. This study investigated how a magnification aid and level of experience with the technique affected the variability and accuracy of ptilochronology measurements. The average width of growth bars was(More)
