1. Introduction
In conservation translocations, habitat suitability is of critical importance for the successful establishment of a population (Germano and Bishop, 2008; Wolf et al., 1998). A suitable, good quality habitat promotes survival and breeding of a newly founded population. In contrast, poor habitat quality at release sites has been shown to incur significant post-translocation losses; for example, 16%–50% of failed cases are associated with poor habitat quality (Brichieri-Colombi and Moehrenschlager, 2016; Germano and Bishop, 2008; Moehrenschlager et al., 2013; Wolf et al., 1996). However, what constitutes habitat quality, and the specific reasons of translocation failure, are often unclear (Ewen and Armstrong, 2007; Fischer and Lindenmayer, 2000; Wolf et al., 1996). Therefore, identifying the ultimate causes for translocation failure due to a ‘poor quality’ site can be challenging. Factors that determine habitat suitability or ‘quality’ are speciesspecific (Ewen et al., 2014). Selecting suitable habitat will depend on understanding the critical ecological requirements for the species in question, as well as the species function within the ecosystem or food web. Previous studies have looked at habitat or landscape characteristics that fit species' requirements for foraging, refuge use, egg-laying sites (Castilla and Swallow, 1995; Ebrahimi and Bull, 2012; Ortiz-Catedral and Brunton, 2009), dispersal or other behaviors (Armstrong and Ford, 2015; Gobiel and Villard, 2008; Parlato and Armstrong, 2013; Richardson et al., 2015; Stamps and Swaisgood, 2007), effect of invasive or anthropogenic threats (e.g., removal of introduced predators, or isolation from the public; Atkinson, 2002; Moseby et al., 2015; Norbury et al., 2014; Towns, 2011; Towns et al., 1997), and climatic differences between sites (e.g., climate change, Fordham et al., 2012; Schwartz and Martin, 2013). In addition to the above, for some species the need for camouflage may be critical for survival, either to avoid predators or to successfully capture prey. The efficacy of visual camouflage is often dependent on the matching of the animal's body color to its immediate background (Merilaita and Stevens, 2011; Stevens and Merilaita, 2011a). Therefore, a potential mismatch between the animals and their new environment may increase their conspicuousness to predators or prey. Three main factors influence effective background-matching in cryptic animals (Houston et al., 2007; Merilaita et al., 2001): 1) phenotypic plasticity and genetic variation of the focal species (e.g., Bergstrom et al., 2012; Cortesi et al., 2015; Morgans and Ord, 2013; Rosenblum, 2005; Tyrie et al., 2015; Westley et al., 2013); 2) the abundance and species composition of predators or prey (e.g., Defrize et al., 2010; Llandres et al., 2011; Rohwer and Paulson, 1987; Stankowich and Coss, 2007;Théry et al., 2004; Troscianko et al., 2013); and 3) the color, structure and complexity of the habitat (e.g., Kekäläinen et al., 2010; Nafus et al., 2016; Nafus et al., 2015). Because each factor influences an animal's conspicuousness across time and space, any change in these factors due to translocation could impact the population at different levels. For example, a population that mismatches with their release site can have lower establishment of founders through reduced individual fitness (inability to hide from predators or to capture prey). Lower founder size will affect recruitment rate, and the phenotypic and genotypic diversity of the translocated population (Armstrong and Wittmer, 2011; Forsman, 2014; Miller et al., 2009; Thrimawithana et al., 2013).
