Movements and wintering areas of breeding age Thick-billed Murre Uria lomvia from two colonies in Nunavut, Canada

first_imgThe non-breeding movements of marine birds were poorly known until recently, but this information is essential to understanding the risk to different geographical populations from events on the wintering grounds. We tracked the migration routes and wintering areas of Thick-billed Murre Uria lomvia from two breeding colonies in eastern Canada: Coats Island in northern Hudson Bay and The Minarets, Baffin Island, during the period August 2007-May 2008 using geolocation loggers. Birds from The Minarets moved south rapidly post-breeding and wintered principally off Newfoundland and southern Labrador, or between Newfoundland and southern Greenland, remaining south of 55A degrees N until at least the spring equinox. Those from Coats Island remained in Hudson Bay until at least mid-November, after which they moved rapidly through Hudson Strait to winter in southern Davis Strait and the northern Labrador Sea, mostly north of 55A degrees N. Many individuals stayed throughout the winter in areas of heavy ice cover. Adults from the two colonies appear to be completely segregated in winter and those from Coats Island probably did not enter the area of the winter hunt in Newfoundland. Unexpectedly, some birds from The Minarets wintered in waters beyond the continental slope and outside the distribution of pack ice, demonstrating that particular individuals can be wholly pelagic throughout the winter. Coats Island birds returned through Hudson Strait as soon as open water areas became available in spring. Their sojourn in Hudson Bay coincided very closely with the occurrence of areas with < 90% ice cover. In spite of the relatively large error in positions obtained from geolocation loggers, our results demonstrated the value of these devices by uncovering a number of previously unknown aspects of Thick-billed Murre non-breeding ecology in the Northwest Atlantic. Comparison of the non-breeding ecology based on SST experienced in winter show that the winter niche is broader than hitherto assumed, demonstrating that separate populations may experience different selection in the face of climate change.last_img read more

Professor to research personality disorders

first_imgPsychology Professor Lee Anna Clark was recently awarded a $2 million grant from the National Institute of Mental Health. The funds will go toward a five-year study to change the way personality disorders are diagnosed. Clark said the project is looking to bridge the gap between personality order identification and designation. “The bottom line for the grant is to gather information that might allow us to build a better system,” Clark said. “There is a mismatch between the way personality disorders are diagnosed and the way they are defined and we want to see if we can bring those into better alignment.” The current diagnostic system uses a certain set of criteria for each personality disorder, Clark said. “It’s proven to be a pretty good measure of personality traits in abnormal range,” she said. “But it’s not perfect and we need to figure out what other traits are necessary.” Clark said the core dysfunction of a personality disorder is an impairment in a person’s sense of self and their ability to relate to other people. “Our personalities are designed to help us function in the world,” she said. “When that personality system doesn’t develop or function properly, that’s a personality disorder.” Clark said one of the main goals of the study is to determine a complete, comprehensive set of personality traits to be used in diagnosing personality disorders. “We want to understand more about the notion of personality functioning, which is a relatively new concept,” she said. “We want to see how we can better measure that coherent sense of self.” Clark said the first two phases of the study involve conducting interviews and gathering data from patients at the Oaklawn Psychiatric Center, a local nonprofit mental health agency. The second phase of the study will take three years, Clark said. “We’ll interview a total of 600 participants and also talk to others who know them well,” she said. “The belief about people with personality disorders is that they don’t have good insight into their own personalities, so they need to get another perspective.” The third and final stage of the study will test the system developed based on the information gathered from the previous two phases, Clark said. “We ultimately want to be able to assess and diagnosis personality disorders using the traits that define them,” she said.last_img read more

New NCUA Chairman Hood outlines areas of focus, ANPR issued

first_imgThe NCUA Board issued an advance notice of proposed rulemaking (ANPR) Thursday on compensation in connection with loans to members. This was also the first meeting of a full, three-person board since April 2016. Rodney Hood was named chair by President Donald Trump earlier this month, and Todd Harper was sworn in as a board member earlier this month as well.The ANPR seeks comments on ways to improve the agency’s regulations limiting credit union officials and employee compensation in connection with loans to members and lines of credit to members.According to the agency, these regulations have generated confusion and are likely outdated, burdensome and at odds with industry standards.NCUA is particularly interested in obtaining commenter feedback on “how it can provide flexibility with respect to senior executive compensation plans that incorporate lending as part of a broad and balanced set of organizational goals and performance measures.” ShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr continue reading »last_img read more
