Biology and Conservation of At-Risk Butterflies
The success of conservation efforts often depends on whether details of the biology of species are overlooked or incorporated (Schultz & Crone 2008; Schultz, Russell & Wynn 2008). Yet, many details of biology of at-risk species are still unknown. Therefore, tackling the issue of documenting basic biology is a thread in many of our research projects (Schultz, Hammond & Wilson 2003; Wilson et al. 2003).
Work in our lab has focused on the following at-risk butterflies: mardon skipper (Beyer & Schultz 2010; Henry & Schultz 2013), Fender’s blue (Thomas & Schultz 2016), Puget blue, and Oregon silverspot. Recent work in the lab expands our work to western monarch and understanding the ecology of this widespread species which is currently in rapid decline across North America (Pelton et al. 2016; Schultz et al. 2017). In addition, we use this natural history research in combination with behavioral and demographic work to develop “rules of thumb” to advance species recovery (Schultz 2015; Schultz & Crone 2015)
