| sediment copper bioavailability to freshwater snails in south florida: risk implications for the everglade snail kite (rostrhamus sociabilis plumbeus). | many properties being acquired as part of the comprehensive everglades restoration plan (cerp) are heavily contaminated with copper. estimated copper bioaccumulation in the florida apple snail (pomacea paludosa) has led to the prediction of risk to the everglade snail kite (rostrhamus sociabilis plumbeus) at some cerp projects. field study results presented in this paper examine the relationship between copper levels in sediments, snails, and other biota. copper concentrations in all biota (snai ... | 2008 | 18679796 |
| importance of well-designed monitoring programs for the conservation of endangered species: case study of the snail kite. | monitoring natural populations is often a necessary step to establish the conservation status of species and to help improve management decisions. nevertheless, many monitoring programs do not effectively address primary sources of variability in monitoring data, which ultimately may limit the utility of monitoring in identifying declines and improving management. to illustrate the importance of taking into account detectability and spatial variation, we used a recently proposed estimator of abu ... | 2007 | 17391197 |
