Molecular forensics in avian conservation: a DNA-based approach for identifying mammalian predators of ground-nesting birds and eggs

摘要: Background The greater sage-grouse (Centrocercus urophasianus) is a ground-nesting bird from the Northern Rocky Mountains and species at risk of extinction in multiple U.S. states Canada. Herein we report results proof concept that mitochondrial nuclear DNAs mammalian predator saliva could be non-invasively collected depredated eggshells carcasses used for identification. Molecular forensic approaches have been applied to identify predators remains as one strategy better understand predator–prey dynamics guide management strategies. This can aid conservation efforts by correctly identifying most likely impact threatened endangered species. DNA isolated non-invasive samples around nesting sites (e.g. fecal or hair samples) method increase success accuracy identification when compared relying on nest alone.
