This data set was collected as part of a structured decision-making workshop designed to identify sources of uncertainty and articulate alternative hypotheses about prescribed fire in high marshes of the Gulf of Mexico. Workshop participants independently scored alternative hypotheses based on a standard rubric using an online system. Following the workshop, we used the scores to compute QVoI for each participant. We used QVoI to prioritize the sources of uncertainty based on their magnitude of uncertainty, relevance for decision making, and reducibility.

This is an antiquated version of the North American Breeding Bird Survey (BBS) dataset that has been superseded by a more recent release. Unless visitors have a specific need for these archived data, they should return to the Main BBS Dataset Page and choose the most recent data release, as that one will include all BBS data released to date. The 1966-2021 North American Breeding Bird Survey (BBS) dataset contains avian point count data for more than 700 North American bird taxa (species, races, and unidentified species groupings). These data are collected annually during the breeding season, primarily in June, along thousands of randomly established roadside survey routes in the United States and Canada. Routes...

The rusty-patched bumble bee (Bombus affinis) is a listed species under the Endangered Species Act of the United States. While understood to be a highly generalist forager, little is known on the role that limited floral resources or shifting floral community composition could have played in B. affinis decline. Determining which floral species provide suitable B. affinis forage could assist conservation efforts where B. affinis persists, identify floral species for restoration efforts, or highlight regions to search for cryptic populations.
Data are included for field surveys conducted for freshwater mussels within the Pine Creek watershed in the Mid-Atlantic region of the United States. Timed search (qualitative) surveys were conducted in ~200 meter sections of river between 1995 and 2009; The number of mussels of each species and associated search time were recorded for each survey section to determine a catch per unit effort (CPUE; number of individuals found per person hour).

A seminal question in ecotoxicology is the extent to which contaminant exposure evokes prolonged effects on physiological function and fitness. A series of studies were undertaken with American kestrels ingesting environmentally realistic concentrations of the second-generation anticoagulant rodenticide (SGAR) brodifacoum (BROD). Kestrels fed BROD at 0.3, 1.0 or 3.0 µg/g diet wet wt for 7 d exhibited dose-dependent hemorrhage, histopathological lesions and coagulopathy (prolonged prothrombin and Russell’s viper venom times). Following termination of a 7 d exposure to 0.5 µg BROD/g diet, prolonged blood clotting time returned to baseline values within a week, but BROD residues in liver and kidney (terminal half-life...

Based on forest patch area, location, and hydrologic influence, we ranked the purported need of forest patches for additional conservation-protection. Qualities for higher ranking included forest patches with & greater than 2000 ha of core-forest that was more than 250 m from an edge, forest patches within high priority areas for reforestation, and forest patches with less propensity for flooding. Digital data are provided for: 1. Boundary of the Mississippi Alluvial Valley study area. 2. Forest cover (circa 2015) used to for determination of forest area in need of conservation protection. 3. The conservation estate (circa 2019) that had conservation protection by virtue of ownership, easement, or servitude. 4....
A heterologous thrombin clotting time assay (TCT) was used to measure the time for conversion of fibrinogen to fibrin using commercially available reagents. Human reference material included in the kit was diluted with imidazole buffered saline (IBS; 0.0125M imidazole-0.109 M sodium chloride, pH7.4) to generate a standard curve. Each kestrel plasma sample was thawed at 37ºC and diluted with IBS, and following incubation at 37ºC, the reaction was then initiated by the addition of bovine thrombin reagent supplied with the assay kit, with clotting time measured to 0.1 s. Fibrinogen concentration was determined in a single assay for each of the 3 study trials, with reference samples interspersed among study samples....
