Abstract Of widespread interest in animal behavior and ecology is how animals search their environment for resources, whether these strategies are optimal. However, movement also affects predation risk through effects on encounter rates, the conspicuousness of prey, success attacks. Here, we use predatory fish attacking a simulation virtual prey to test associated with behavior. Despite often b...

-Cackling Geese (Brunta canadensis minima) were preyed on heavily in northeastern California by Golden Eagles (Aquila chysaetos) and less commonly by Bald Eagles (Haliaeetus Zeucocephalus) in 19851990. Eagle predation on Cackling Geese was minimal in other wintering locations in California. In the Klamath Basin, eagles killed Cackling Geese most frequently soon (<IO days) after the geese arrive...

Background: This study aimed to evaluate UAV images of Pinus taeda L. stands for classifying trees attacked by Sapajus nigritus in Southern Brazil. were acquired on March 2018, using a DJI Phantom Pro 4 over 18.73 hectares. We evaluated different band compositions and vegetation indices. Using photo interpretation based the color crown field measurements, manually labeled as not attacked, dead,...

Today, there are varieties of methods for determining the risk flooding in different areas a catchment. However, use GIS-based weighting is receiving increasing attention among researchers. In early 2019, severe and continuous floods occurred some provinces Iran. Khorramabad was one cities most affected by floods. Regrettably, during construction development city, minimum distance from roads vi...

The early studies on conjugase from chicken pancreas (1, 2) did not lead to the identification of this enzyme. Subsequent progress in the elucidation of the chemical structure of pteroylglutamic acid (3) and its derivatives (4, 5) left little doubt that conjugase is one of the peptidases. Pfiffner et al. (4) classified the conjugase enzymes as carboxypeptidases after they showed that the methyl...
