Sympatric Nesting Eastern Prairie Population (EPP) Canada Geese and Lesser Snow Geese on the Hudson Bay Lowlands: Nest Depredation and Spatial Distribution (2004 Annual Report)
No full textCurrently, there is concern about the influence of increasing nesting light goose populations (lesser snow goose [Chen caerulescens caerulescens] and Ross’s goose [Chen rossii]) on breeding Canada geese (Ankney 1996, Batt 1997, Walter 1999, Nack 2003, Nack and Andersen 2004, Gleason et al. 2004), and the potential interacting effects of predators and light goose abundance on Canada goose population dynamics in northern Manitoba.

Eastern Population of Greater Sandhill Crane Global Postioning System Data
No full textThe dataset consists of 29 .txt files are comma separated time stamped ASCII data files where each record has its own unique timestamp. The header line for each file contains unique variables defined in an attached readme file.GPS location data was collected where Eastern Population sandhill cranes occupied during breeding and wintering seasons and within migration corridors and consisted of states and provinces within the Canadian Shield, Great Lakes, Mississippi Valley, and Southeast geographic regions of North America.U.S. Fish and Wildlife Service, Webless Migratory Game Bird ProgramU.S Geological SurveyNorthern Prairie Wildlife Research Center, the University of MinnesotaMinnesota Cooperative Fish and Wildlife Research Unit (Research Work Order no. 86)U.S. Fish and Wildlife Service, Migratory Bird Management OfficeFronczak, David L; Andersen, David E.

RESEARCH AND MONITORING PLAN FOR NORTHERN GOSHAWKS (Accipter gentilis atricapillus) IN THE WESTERN GREAT LAKES REGION, 1999
No full textBecause the northern goshawk (Accipiter gentilis atricapillus; hereafter referred to as goshawk) often nests (Siders and Kennedy 1996; Squires and Ruggiero 1996) and hunts (Bright-Smith and Mannan 1994; Beier and Drennan 1997) in mature forests, potential conflicts between timber harvest and maintenance of viable goshawk populations concerns various publics (Kennedy 1997). Due to these concerns, the U. S. Fish and Wildlife Service (FWS) recently conducted a status review of goshawk populations west of the 100th meridian to determine if listing this population as threatened under the Endangered Species Act (ESA) was warranted (Clark 1997).Kennedy, Patricia L; Andersen, David E.

RESEARCH AND MONITORING PLAN FOR NORTHERN GOSHAWKS (Accipter gentilis atricapillus) IN THE WESTERN GREAT LAKES REGION, 2005
No full textConservation of northern goshawks (Accipiter gentilis atricapillus) in the western Great
Lakes region (the northern forested portions of Michigan, Minnesota, and Wisconsin and the southern
forested portions of Ontario) is hampered by a lack of population data and information about
goshawk-habitat relations. In this report, we provide a brief summary of existing information on
goshawks in the WGLR, and conclude that existing data are few and have limited applicability to
regional conservation and monitoring of the breeding goshawk population. Furthermore, we identify
important considerations in establishing monitoring protocols for goshawks, and suggest approaches
to address limitations associated with existing data.Kennedy, Patricia L; Andersen, David E. (2005).

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
