Methods General approach Our tree construction approach combines relaxed clock molecular trees of well-supported avian clades with a fossil calibrated backbone with representatives from each clade. It is neither a typical supertree (i.e. a combination of existing trees) nor a supermatrix approach (a single analysis applied to the entire genetic data matrix). We follow four steps: Each species is assigned to one of 158 clades; Relaxed-clock trees are generated for each clade; Species without genetic information are partially constrained within their clade based on a combination of consensus trees from step 2 and taxonomic information.

UNC Charlotte Biology Welcome to my cyber-résumé. Browse around to find out about my research and publications on birds of prey, birds of the New World Tropics, habitat fragmentation in the Amazon, ecology, and conservation, as well as my graduate students, courses taught (ornithology and sometimes field ecology), and links to interesting pages on the Web, including a number of local conservation organizations with which I'm involved. Ospreys: I've been studying the Osprey population on Martha's Vineyard, MA, since 1969. Beginning in 2000, in collaboration with Dr. Mark Martell of The Raptor Center at the University of Minnesota, I put satellite transmitters on a total of seven adult birds, six on Martha's Vineyard and one in Charlotte.

Although the 1997-2014 Edition of the National Atlas of the United States was retired in September 2014, The National Map recognizes the importance of continuing to make a collection of the small-scale datasets, originally developed for the National Atlas, available to users. Small-scale maps have an advantage over large-scale maps when there is a need to show a large area in a single view. This makes small-scale maps an ideal solution for scientists, decision-makers, and planners needing to provide a geographical context for the research projects. Generally, certain geographical and feature details found in large-scale maps are limited or omitted in small-scale maps.

Birds With Child-care Assistance Invest Less In Eggs An Australian bird has been found to produce smaller, less nourishing eggs when it breeds in the presence of other 'helper' birds that provide child-care assistance. This unique adaptation enables the birds to live longer and breed more often than females without helpers. The research, led by a University of Cambridge academic, was published in Science. In many animal species, parents caring for their offspring are assisted by so-called 'helpers', adults that forego reproduction to help others raise young. Although parents decrease the amount of food they provide to offspring when helpers are present, the additional supply provided by the helpers more than compensates for this reduction.

International Programs - Information Gateway Frequently Asked Questions (FAQ) 1. What is the International Data Base? The International Data Base (IDB) offers a variety of demographic indicators for countries and areas of the world with a population of 5,000 or more. World and Region demographic indicators in the IDB, including population totals, exclude the populations of countries and areas with fewer than 5,000 people. The IDB has provided access to demographic data for over 25 years to governments, academics, other organizations, and the public.

Australian birds attract mates with 'scary movie effect' Using a horror film to bring your date closer is a classic move in the teenage playbook. Now, a study of Australian birds finds that other animals use the same "scary movie effect" to attract female attention, by hitchhiking mating signals onto the calls of predators. Male splendid fairy-wrens, a sexually promiscuous small bird native to Australia, are known to sing a special song each time they hear the call of one of their predators, the butcherbirds.
