| risk assessment of lead poisoning and pesticide exposure in the declining population of red-breasted goose (branta ruficollis) wintering in eastern europe. | the red-breasted goose branta ruficollis is a globally threatened species (iucn vulnerable) and the only european goose species currently in decline. working on the wintering grounds on the black sea coast, we address two potential causes of decline of this species for the first time: lead poisoning, and contamination from pesticides. we quantified the densities of spent pb shot in three wetlands used by the geese in north-east bulgaria, and analysed the pb concentration in the faeces of red-bre ... | 2016 | 27529395 |
| a tree of geese: a phylogenomic perspective on the evolutionary history of true geese. | phylogenetic incongruence can be caused by analytical shortcomings or can be the result of biological processes, such as hybridization, incomplete lineage sorting and gene duplication. differentiation between these causes of incongruence is essential to unravel complex speciation and diversification events. the phylogeny of the true geese (tribe anserini, anatidae, anseriformes) was, until now, contentious, i.e., the phylogenetic relationships and the timing of divergence between the different g ... | 2016 | 27233434 |
| stress influence on plasma protein electrophoresis in the red-breasted goose (branta ruficollis) and hawaiian goose (branta sandvicensis). | the objective of this study was to evaluate the effects of stress (as measured by total heterophil + eosinophil counts [thecs] and plasma corticosterone [pc] levels) on plasma protein electrophoresis (ppe) in two anseriform species. ten red-breasted geese ( branta ruficollis ) and eight hawaiian geese (branta sandvicensis) were received into quarantine at beauval zoo and housed together with other anseriformes. two days later, all were examined as part of routine quarantine procedures, and blood ... | 2017 | 28363046 |
