The Red-knobbed Coot Fulica cristata is an abundant aquatic bird in South Africa and was anticipated to have indicator abilities for metal pollution. This hypothesis was tested on 83 coot samples collected from five selected aquatic ecosystem areas supporting substantial coot populations, of which various abiotic and biotic components are known to contain varying levels of a number of metals. T...

Coot is a molecular-graphics program primarily aimed at model building using X-ray data. Recently, tools for the manipulation and representation of ligands have been introduced. Here, these new tools for ligand validation and comparison are described. Ligands in the wwPDB have been scored by density-fit, distortion and atom-clash metrics. The distributions of these scores can be used to assess ...

the aim of this study is to determine of mercury levels in various internal organs of the fereydunkenar international wetland’s birds for the first time and to determine the influence of this metal on their health. this study has been done in the fereydunkenar international wetland where is the most important wetland habitat of the central areas of hyrcanian ecosystem. fereydunkenar internation...
