• Long-Term Assessment of the Effects of Transgenic Bt Cotton on the Abundance of Nontarget Arthropod Natural Enemies (2005, background): “Ultimately, the assessment of environmental impacts such as nontarget effects need to weight the importance of both type I and type II error rates as well as biologically relevant effect sizes to provide meaningful guidelines for experimental design (Di Stefano 2003).”
• Litter N:P ratios indicate whether N or P limits the decomposability of graminoid leaf litter (2006, background): “This criterion was chosen to minimise both type I errors (find ‘effects’ due to chance) and type II errors (fail to detect real effects), as both error types could distort relationships between the occurrence of treatment effects and litter quality (Stefano 2003).”
• Indicators to support an ecosystem approach to fisheries (2005, background): “Thus the acceptable power and significance level used should depend on these potential costs (Di Stefano 2003).”
• Effects of grazing and invasive grasses on desert vertebrates in California (2012, background): “However, a growing body of literature, as reviewed by di Stefano (2003), suggests that such a conservative alpha level may not be justified in some circumstances, especially where the possibility of committing a Type II error (accepting a false null) would result in undesirable consequences to…”
• Potential impacts of wave-powered marine renewable energy installations on marine birds (2010, background): “…of the expanding offshore wind industry have been the focus of much research (Desholm & Kahlert 2005, Chamberlain et al. 2006, Desholm et al. 2006, Dierschke et al. 2006, Drewitt & Langston 2006, Hüppop et al. 2006, Masden et al. 2009), although the impact of offshore windfarms on the population…”
