In situ effects of pesticides on amphibians in the Sierra Nevada

Abstract: For more than 20 years, conservationists have agreed that amphibian populations around the world are declining. Results obtained through laboratory or mesocosm studies and measurement of contaminant concentrations in areas experiencing declines have supported a role of contaminants in these declines. The current study examines the effects of contaminant exposure to amphibians in situ in areas actually experiencing declines. Early larval Pseudacris regilla were translocated among Lassen Volcanic, Yosemite and S… Show more

“…A single-factor approach in an artificial environment, combined with the use of model organisms as surrogates for entire taxa, does not account for many ecological processes that ultimately affect exposure outcomes under field conditions (Boone and James 2005). But this gap between laboratory and field conditions can be bridged, using outdoor mesocosms (Relyea 2006) and in situ studies in known contaminated field sites (Sparling et al 2015). Utilizing outdoor mesocosms effectively increases realism while retaining control of the factors being tested (Boone and James 2005).…”

“…This continued agricultural growth can be partly attributed to pesticides, which are used prominently in the state for pest management. The problems associated with heavy pesticide use are well documented, and in some California National Parks, pesticides are found ubiquitously across diverse biological and physical endpoints (LeNoir et al, 1999;Landers et al, 2008;Flanagan Pritz et al, 2014;Sparling et al, 2015).…”
