Dna From Feces And Museum Specimens Confirms A First State Record Bird, Alec R. Lindsay Ph. D., Skye C. Haas
Dna From Feces And Museum Specimens Confirms A First State Record Bird, Alec R. Lindsay Ph. D., Skye C. Haas

In October 2005, a vagrant kingbird (Aves: Tyrannus sp.) appeared in Michigan’s Upper Peninsula, nearly 2000 km from the northern limit of its usual range. Using mitochondrial DNA obtained from a fecal sample deposited by the bird and mitochondrial DNA isolated from museum reference specimens, the species iden- tity of this bird was definitively confirmed as a Tropical Kingbird (T. melancholicus) rather than a Couch’s Kingbird (T. couchii). This is the first time DNA evidence has been used to establish a state bird record, and one of the few studies of any type to successfully use avian feces for DNA …

Based on morphology there are currently three described East African species of torrent frogs belonging to the tropical African genus Petropedetes (P. dutoiti, P. martiennseni and P. yakusini). Taxonomic uncertainties are evident within this group: a putative new species reported from the Nguru Mountains and the species P. yakusini have a fragmented distribution across the Southern Tanzanian highlands. We conducted a molecular systematic study, sampling populations of East African petropedetids occurring in the mountains of Tanzania (P. martiennseni and P. yakusini), to investigate species boundaries and biogeography. Data provide evidence for the recognition of …
Age Structure Of Moose (Alces Alces) Killed By Gray Wolves (Canis Lupus) In Northeastern Minnesota, 1967–2011, L. David Mech, Michael E. Nelson

The ages of 77 adult Moose (Alces alces) killed by gray Wolves (Canis lupus) during the period 1967–2011 in northeastern Minnesota were significantly older than those of a sample of 17 585 Moose killed by hunters in nearby Ontario. Our findings support those of earlier studies of protected Moose populations in national parks that found that gray Wolves tend to kill disproportionately more older Moose.
