Abstract In efforts to prevent extinction, resource managers are often tasked with increasing genetic diversity in a population of concern to prevent inbreeding depression or improve adaptive potential in a changing environment. The assumption that a

Feather quality in birds is considered an honest signal of individual health as feather appearance and function depend on an individual’s ability to maintain them. In addition to flight and insulation, feathers are essential for social interactions

Trait genetic architecture influences how populations evolve and adapt. Genomic analysis finds that an inversion links genetic variation controlling redpoll finch color and bill shape, allowing the maintenance of latitudinal ecotypes despite a genome

We examined long-term demography of an endangered subspecies, the Northern Aplomado Falcon (Falco femoralis septentrionalis), in South Texas, USA. The population has been managed and monitored since reintroductions began in 1993. Data spanning 1993

Morphological measurements of Atlantic puffin (Fratercula arctica naumanni) in High-Arctic Greenland
Publikováno v:
Polar Research, Vol 39, Iss 0, Pp 1-12 (2020)
Morphological measurements of 45 adult Atlantic puffins Fratercula arctica were collected in High-Arctic Greenland between 2010 and 2016. Measurements support that the population belongs to the F. a. naumanni subspecies and were significantly larger

An accelerating decrease in summer sea-ice extent in the Arctic Ocean and Canadian Arctic Archipelago (North-west Passage) is predicted to increase the movement of species between the North Pacific and North Atlantic oceans. Here we report observatio

Although the Atlantic puffin Fratercula arctica is well studied throughout its temperate and low Arctic breeding range, few have studied the species in its far northern distribution. This study is the first to present data on the migratory movements

With reference to concepts developed in Trouble Songs: A Musicological Poetics, our objective is to locate trouble (and “trouble”) in and around song, while attending to media forms, transmission processes, and embodied figures that carry trouble

Mucosal infection by the human papillomavirus (HPV) is responsible for a growing number of malignancies, predominantly represented by cervical cancer and oropharyngeal squamous cell carcinoma. Because of the prevalence of the virus, persistence of in

Our ability to monitor populations or species that were once threatened or endangered and in the process of recovery is enhanced by using genetic methods to assess overall population stability and size over time. This can be accomplished most directl
