flmnh-242	Nickerson, Max; Pitt, Amber	Historical turtle population decline and community changes in an Ozark River	2012	12	.pdf	application/pdf	4826	280	57	Turtle population decline and community changes in an Ozark River 265 overwintering of G. geographica have occurred in the northern portion of the species’ range where turtles must deal with extreme cold, ice, and anoxic conditions (Ultsch 2006). Documenting population estimates and trends is essential for identifying and conserving imperiled populations (Gibbons et al. 2000) and every attempt should be made to use and publish historical data in order to evaluate changes in turtle populations and minimize the shifting baseline effect that often occurs with studies of declining populations (Pauly 1995; Zeller et al. 2005).	cache/flmnh-242.pdf	txt/flmnh-242.txt
