Microbial diversity and host-specific sequences of Canada goose feces.
Methods to assess the impact of goose fecal contamination are needed as the result of the increasing number of Canada geese (Branta canadensis) near North American inland waters. However, there is little information on goose fecal microbial communities, and such data are important for the development of host-specific source-tracking methods. To address this issue, 16S rRNA gene clone libraries ...
متن کاملThe status of Canada Goose Branta canadensis subspecies in Greenland
Three subspecies of the Canada Goose (Branta canadensis interior, B.c. parvipes and B.c. hutchinsii) have been reported from Greenland, where the species has increased dramatically as a breeding and summering bird in the last 30 years. We report results of catch data, new observations, re-examination of archive photographs and museum specimens that show the subspecies interior is the most commo...

متن کاملEvaluation of Resident Canada Goose Movements to Reduce the Risk of Goose-Aircraft Collisions at Suburban Airports
Resident (non-migratory) Canada goose (Branta canadensis) populations in suburban environments pose risks to human health and safety. Specifically, the relatively large size and gregarious behavior of geese combined with an overlap in aircraft flight space pose substantial risk of property damage and human fatalities from goose-aircraft collisions. We estimated home range and core use areas of ...
متن کاملmtDNA from fossils reveals a radiation of Hawaiian geese recently derived from the Canada goose (Brantacanadensis).
Phylogenetic analysis of 1.35 kb of mtDNA sequence from fossils revealed a previously unknown radiation of Hawaiian geese, of which only one representative remains alive (the endangered Hawaiian goose or nene, Branta sandvicensis). This radiation is nested phylogenetically within a living species, the Canada goose (Branta canadensis) and is related most closely to the large-bodied lineage withi...
