In the United States, the Silver Shiner occurs primarily in the Ohio River Basin, excluding the Western Lowlands, and in the upper Tennessee River watershed (Gilbert, 1980; COSEWIC, 2011).
Further, TEK has contributed new information and insight about marine mammals, generally in the fields of biology and ecology, and specifically in regard to estimating population numbers, defining stock structure, managing bowheads and belugas in Alaska, and redefining stock status of bowheads in Canada (Huntington, 2000a; NWMB, 2000; Fernandez-Gimenez et al.,, 2006; COSEWIC, 2009).
Dace species are known to be opportunistic feeders; however, from diet analysis and my own (AJM) observation of prevalent food sources it can be concluded that Umatilla Dace in the Colville River target caddisflies during the summer months, while in British Columbia diet was composed mainly of mayflies (Ephemeroptera) and midges (Chironomidae) (COSEWIC 2010).
Though this is in part due to COSEWIC's progress in dealing with a backlog in the designation process, it is also due to an array of escalating environmental problems.
COSEWIC assessment and update status report on Keen's Long-eared Bat Myotis keenii in Canada.
Western Pond Turtles may live >40 y (Bury and Germano 2008), and although the lifespan of the Painted Turtle is not as well documented, Painted Turtles in the wild may live 50 y or longer (COSEWIC 2006).
Predictions generally align with what is known of this species' preference for open waters [less than or equal to] 10 m deep with relatively stable, warm temperatures (Kinney, 1954; Smith, 1985; Parker et al., 1987; COSEWIC, 2013).
Unexploited beluga populations that are below carrying capacity appear to increase at a rate of 2.5% to 3.5% (and possibly as high as 4%) per year (COSEWIC, 2004).
Previous field estimates suggesting a single female can lay 300 to 800 eggs in a season (Stebbins 1985, 2003; Leonard and others 1993; Cannings and others 1999; COSEWIC 2007; Matsuda and others 2007) may be an underestimate by a factor of 1.7 times.
Also, because of this herd's small size, its vulnerability to harvest, and the potential future impacts of natural or anthropogenic alteration of the sea ice, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) assessed these caribou as a species of special concern (COSEWIC, 2004).
This species is listed as a top priority for conservation action by Partners in Flight (Hamel et al., 2004) with a federal and state listing of "Endangered" in Canada (COSEWIC, 2010) and Indiana (
