| pesticide concentrations in frog tissue and wetland habitats in a landscape dominated by agriculture. | habitat loss and exposure to pesticides are likely primary factors contributing to amphibian decline in agricultural landscapes. conservation efforts have attempted to restore wetlands lost through landscape modifications to reduce contaminant loads in surface waters and providing quality habitat to wildlife. the benefits of this increased wetland area, perhaps especially for amphibians, may be negated if habitat quality is insufficient to support persistent populations. we examined the presence ... | 2015 | 25244036 |
