Brodifacoum toxicity in American kestrels (Falco sparverius) with evidence of increased hazard upon subsequent anticoagulant rodenticide exposure - Results of trial 3

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...

Spatio-temporal distribution models for dabbling duck species across the continental United States

These data describe the spatio-temporal distribution of dabbling duck species across the continental United States during four biologically relevant seasons. This dataset contains two types of distribution models: (1) probability of presence, and (2) abundance. The model type, species, and season depicted in a raster are defined in the file name. File names begin with either abun (...
