No full textRelease 1.0Crews from the United States Forest Service and University of Minnesota – Natural Research Institute captured 28 bats at Cloquet Forestry Center from June 6th – 10th, 2016. Bats of three species were captured during mist-netting surveys. We captured 10 individuals of our target species, the northern long-eared bat, and attached transmitters to 4 adult females. These four were tracked to 7 unique roost trees of 2 species and 1 Cloquet Forestry Center building. During emergence counts we counted from 1 to 23 bats emerging from the roost trees. We observed 64 bats emerging during an emergence count at the building. Roost trees varied in diameter and height, as well as decay stage. The roosting patterns observed at Cloquet Forestry Center were similar to roosting patterns we have observed in other areas of Minnesota, where bats appear to be using a variety of available trees. This report details work done in Cloquet Forestry Center as part of a statewide study of northern long-eared bats. A report summarizing results of the statewide project will be available in early 2017.Land, Water and Environment, Natural Resources Research Institute, University of Minnesota Duluth, Duluth, MN; Superior National Forest, USDA – Forest Service, Duluth, MN; Chippewa National Forest, USDA – Forest Service, Cass Lake, MN; Biology Department, Swenson College of Science and Engineering, University of Minnesota Duluth, Duluth, MN; Division of Ecological and Water Resources, Minnesota Department of Natural Resources, St. Paul, MN; Funding for this project was provided by the Minnesota Environment and Natural Resources Trust Fund (ENRTF) as recommended by the Legislative‐Citizen Commission on Minnesota Resources (LCCMR).Swingen, Morgan; Catton, Timothy; Kirschbaum, Kari; Moen, Ronald; Baker, Richard.

No full textRelease 1.0Crews from the USDA – Forest Service captured 43 bats in the Superior National Forest in June and July
of 2016. Bats of five species were captured during mist-netting surveys. We captured 13 individuals of
our target species, the northern long-eared bat, and attached transmitters to 7 adult females (3 nonreproductive,
one pregnant, and three lactating). These seven bats were tracked to 13 unique roost trees of
3 species. During emergence counts we counted from 1 to 26 bats emerging from these roost trees. Roost
trees varied in DBH and height as well as decay stage. Roosting patterns in the Superior National Forest
were similar to roosting patterns we have observed in other areas of the state, where bats appear to be
using a variety of available trees. This report details work done in the Superior National Forest as part of

No full textRelease 1.0Crews from the USDA – Forest Service, University of Minnesota - Natural Resources Research Institute, Minnesota Army National Guard (MNARNG), and Minnesota Department of Natural Resources captured 646 bats throughout the forested region of Minnesota from June 6 – July 21, 2016. Bats of 8 species were captured during mist-netting surveys, including the first evening bat (Nycticeius humeralis) confirmed in Minnesota. We captured 95 individuals of our target species, the northern long-eared bat, and attached transmitters to 45 adult females (39 reproductive, 6 non-reproductive or undetermined). These 45 bats were tracked to 111 unique roost trees of at least 20 species. Crews conducted emergence counts at roost trees and observed between 1-71 bats emerging. Roost trees varied in both DBH and height, as well as decay stage. The roosting patterns observed in 2016 were similar to those seen in 2015, where bats appear to be using a variety of available trees.University of Minnesota Duluth, Natural Resources Research Institute, 5013 Miller Trunk Highway, Duluth, MN 55811-1442; Funding for this project was provided by the Minnesota Environment and Natural Resources Trust Fund (ENRTF) as recommended by the Legislative‐Citizen Commission on Minnesota Resources (LCCMR).Swingen, Morgan; Baker, Richard; Catton, Timothy; Kirschbaum, Kari; Nordquist, Gerda; Dirks, Brian; Moen, Ronald.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
