Managers of U. S. Fish and Wildlife Service’s Bald Knob National Wildlife Refuge (Refuge) in central Arkansas want to provide sufficient habitat resources to meet its population objectives for wintering waterfowl. Nutrient reserves acquired during the wintering period appear to support spring migration and subsequent reproductive success for some species,...
Postmortem diagnostics play an important role in the ability to understand the cause of death of an animal. However, removal from oxygen supply, either by surgical excision or at death, leads to cell and tissue decomposition. Knowledge about factors impacting reliability of test results is extremely important for accurate diagnostics....
Black Rockfish are important commercial and recreational species and understanding their biology is useful in developing best management practices. A common means to assess diet in both freshwater and marine fishes is stomach content analysis, which can determine diet composition and infer foraging behaviors. We conducted a stomach content analysis...
In surveys of residents in three urban and three rural locations in the Great Basin we examined the social acceptability of six management practices showing promise for restoring sagebrush-dominated rangelands. Unlike most studies of range management perceptions that have relied on single measurements, we used longitudinal data from a questionnaire...
Contaminants are ubiquitous in the environment, often reaching aquatic systems. Combinations of forestry use pesticides have been detected in both water and aquatic organism tissue samples in coastal systems. Yet, most toxicological studies focus on the effects of these pesticides individually, at high doses, and over acute time periods, which,...
Beauveria sinensis sp. nov. was isolated from a larva of Geometridae (Lepidoptera) collected from Tiantangzhai, Anhui province, China. It is characterized by elongated ellipsoidal to cylindrical conidia, solitary conidiogenous cells that are cylindrical or with slightly swollen bases, white to pale pink colony in culture, and small mycelial pellets consisting...
Although calderas and the caldera cycle are well studied, the relationship between caldera-forming eruptions and post-caldera volcanism is poorly understood. The chemical characteristics of the erupted products suggest that two end member compositions are involved during resurgence: (1) remnant magma of similar composition to the magma of the climactic eruption;...
Objective: To screen different solvent extracts of Elaeagnus kologa (E. kologa) leaf to determine the phytochemicals, potent antioxidant and antibacterial activity to find out the possible source of applied pharmaceutical formulations.
Methods: Solvent extracts of leaf material were prepared using the Soxhlet apparatus. A study was performed on antioxidant activity...
Environmental DNA (eDNA) is an emerging biological monitoring tool that can aid in assessing the effects of forestry and forest manufacturing activities on biota. Monitoring taxa across broad spatial and temporal scales is necessary to ensure forest management and forest manufacturing activities meet their environmental goals of maintaining biodiversity. Our...
Bird scaring lines (BSLs) protect longline fishing gear from seabird attacks, save bait, reduce incidental seabird mortality and are the most commonly prescribed seabird bycatch mitigation measure worldwide. We collaborated with fishermen to assess the efficacy of applying BSL regulations from the demersal longline sablefish fishery in Alaska to a...
