Context dependence of personalities: risk-taking behavior in a social and a nonsocial situation (2005, background): “, 2003), food properties (Cooper, 2000), and the absolute and relative predation risk (Martin and Lopez, 1999).”
Predator lethality, optimal escape behavior, and autotomy (2010, background): “Flight initiation distance of intact individuals decreases in the presence of food, indicting a trade-off between predation risk and foraging opportunity (Cooper 2000; Cooper and Pérez-Mellado 2004; Cooper et al. 2006).”
Shifted balance of risk and cost after autotomy affects use of cover, escape, activity, and foraging in the keeled earless lizard (Holbrookia propinqua) (2003, methodology): “…running speed increases with body temperature within a fairly wide range of temperatures (Bennett 1980; Huey 1982), body temperature and activity are correlated with substrate temperature (Judd 1975), and H. propinqua permit predators to approach closer before fleeing when warmer (Cooper 2000b).”
Relationships between head size, bite force, prey handling efficiency and diet in two sympatric lacertid lizards (2002, background): “The latter effect may explain why a variety of other lizard species also need more time to subdue large or hard-bodied prey (Pough & Andrews 1985; Grimmond, Preest & Pough 1994; Andrews & Bertram 1997; Pough, Preest & Fusari 1997; Cooper 2000 ).”
