The right tool for the right question: contrasting biogeographic patterns in the notothenioid fish spp. along the Magellan Province.

Molecular-based analysis has become a fundamental tool to understand the role of Quaternary glacial episodes. In the Magellan Province in southern South America, ice covering during the last glacial maximum (20 ka) radically altered the landscape/seascape, speciation rates and distribution of species. For the notothenioid fishes of the genus in the area are described two nominal species.

Contrasting biogeographical patterns in Margarella (Gastropoda: Calliostomatidae: Margarellinae) across the Antarctic Polar Front.

Members of the trochoidean genus Margarella (Calliostomatidae) are broadly distributed across Antarctic and sub-Antarctic ecosystems. Here we used novel mitochondrial and nuclear gene sequences to clarify species boundaries and phylogenetic relationships among seven nominal species distributed on either side of the Antarctic Polar Front (APF). Molecular reconstructions and species-delimitation analyses recognized only four species: M.

Distribution of the genus (Crustacea, Copepoda, Calanoida, Centropagidae) at high latitudes in South America and the main Antarctic biogeographic regions.

Copepods are present in numerous aquatic environments, playing key roles in food webs, and are thought to be useful indicators of environmental change. is a calanoid copepod genus distributed mainly in the Southern Hemisphere, with 14 species reported at higher southern latitudes in South America and Antarctica. We present an updated database of these 14 species of generated from a combination of three sources: 1) new field sampling data, 2) published records, and 3) Global Biodiversity Information Facility (GBIF), to provide a comprehensive description of the geographic distribution of the genus south of latitude 40°S in southern South America and the three main terrestrial biogeographic regions of Antarctica.

Facility Closure: How to Get In, Get Out, and Get What Is Important.

This article examines the current state of affairs of the health information management role in facility closure as well as the impact on revenue cycle operations. Health information management professionals are uniquely positioned to assist an organization in closure efforts because of their knowledge of revenue cycle operations, ability to work with the software products used to generate and store patient information, and solid understanding of the process of care and treatment of the patient. This information is integral to ensuring that patient information in a variety of formats and locations is properly secured and saved so that it will be available to patients and caregivers who need it after the facility closes.
