Mammals of Prince Edward Island and adjacent marine waters
No full textThis long overdue book provides a comprehensive guide to the Island’s terrestrial and marine mammals. Rooted in historical accounts and local research, this book illuminates the lives of PEI mammals large and small. From the Little Brown Bat to the Sowerby’s Beaked Whale, this book highlights each species in illustrated detail and outlines the continued need for conservation efforts. No other Canadian province has lost such a large proportion of its mammal species due to the conversion from a forested to a predominantly agricultural landscape. In the 20th century, many marine mammals were so rare due to prior centuries of human exploitation that any sightings or strandings on PEI were recorded. The expansion of forest cover and the continued efforts of local wildlife and conservation agencies, along with the use of new and refined study techniques on land and in the sea, continue to improve our ability to understand and protect the native mammals of PEI
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
Bioaccumulation of contaminants in amphibians in historical gold mining areas of Nova Scotia
Full text link1 online resource (vii, 43 pages) : colour illustrations, colour maps, charts, graphsIncludes abstract.Includes bibliographical references (pages 40-43).Nova Scotia has a long history of gold mining dating back to the mid-1800’s. Early
mining techniques depended on the use of liquid mercury (Hg). As there were little or no
environmental regulations at the time, over 3,000,000 tonnes of mine waste (tailings) were
released into the environment. These tailings can contain high concentrations of toxic chemicals
including Hg and arsenic (As). Such chemicals have negative effects on the environment and on
wildlife. Frogs are often used as indicators of environmental conditions. Their thin, permeable
skin and semi-aquatic lifestyle can lead to the bioaccumulation of toxins in frog tissues. This
study compares bioaccumulation of Hg in frogs collected from six research sites and one
reference site from within historical gold mining districts in Nova Scotia, Canada. Dried, ground
frog-leg tissues were analyzed for Hg content using a Milestone DMA 80 direct mercury
analyzer. This project tests the hypothesis that if concentrations of Hg are high at research sites
identified as legacy tailing areas in Nova Scotia, then the concentrations of total mercury content
(THg) in the tissues of amphibians collected at the respective sites will also be high. Adult
amphibians sampled from contaminated sites had concentrations of THg ranging from 0.1324 -
2.1329 mg/kg. Tadpoles sampled from contaminated sites had concentrations of THg ranging
from 0.1384 -15.9412 mg/kg. The THg concentrations in adult amphibians at a reference site
ranged from 1.664 – 2.3959 mg/kg. The THg concentrations in tadpoles at the reference site
ranged from 0.0494 – 3.3312 mg/kg. These ranges indicate elevated Hg levels in both adult
amphibians and tadpoles. This project, as part of the legacy gold mine contaminants research led
by the Dynamic Environment and Ecosystems Health Research (DEEHR) team at Saint Mary’s
University will enhance the understanding of impacts of historical human activity on aquatic
ecosystems
The Ocean Pout, Zoarces americanus, and the Ocean Sunfish, Mola mola: Additions to the Marine Ichthyofauna of the Lower Saint John River System, New Brunswick, with a Summary of Marine Fish Reported from the Estuary
Full text linkRecent records for the Ocean Pout, Zoarces americanus (collected 11 February 2011), and the Ocean Sunfish, Mola mola (photograph taken 24 June 2012), in the lower Saint John River system, New Brunswick, add to the list of marine fishes reported from this oceanographically unique estuary system. A total of 62 species of strictly freshwater, anadromous, catadromous, and marine fishes have now been recorded in the Saint John River system, with 49 of these in the Saint John River sensu stricto. The Acadian Redfish, Sebastes faciatus, a species assessed as threatened by the Committee on the Status of Endangered Wildlife in Canada, appears to be among these. While strictly marine fishes may contribute relatively little to the overall biomass of fishes in the Saint John River system, marine species account for 30.6% of the biodiversity of fishes in the river to date. This suggests that marine fishes may be a more significant component of the ichthyofauna of the lower Saint John River system than is generally recognized
Variations on the Author
Full text link“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
