The wildlife risk assessment that could: overcoming sparse dose-response data. Risk assessments for wildlife species are plagued by a lack of dose-response data tailored for those wildlife species. Although data may exist for different endpoints in the same or related animal taxa, such data remains difficult to evaluate and incorporate. Ryan Hill and colleagues offer solutions to tackling this problem in their critical review appearing in the January 2014 issue of IEAM. Hill et al. prescribe tips for compiling sparse data to make it relevant, demonstrate graphical evaluations of sparse data, and discuss modeling options for simple vs. complex data sets.
