Hematological differences between stingrays at tourist and non-visited sites suggest physiological costs of wildlife tourism. (2009, background): “The chicks of the hoatzin, Opisthocomus hoatzin, however, had lower body mass and higher mortality (Müllner et al., 2004), and yellow-eyed penguins (M. antipodes; Ellenberg et al., 2007) had higher chick mortality and lower fledgling weight as a result of tourist visitation, using the same hormone…”
Effects of habituation, research and ecotourism on faecal glucocorticoid metabolites in wild western lowland gorillas: Implications for conservation management (2014, background): “This seems to be the case in Magellanic penguins (Spheniscus magellanicus) exposed to tourism (Walker et al., 2005) and is well documented in research investigating the stress impacts of wildlife tourism on other animal species (Fowler, 1999; Millspaugh and Washburn, 2004; Müllner et al., 2004).”
Concentration of fecal cortisol metabolites in chamois in relation to tourist pressure in Tatra National Park (South Poland) (2013, background): “Human recreation in natural areas does not only affect stress hormone levels but also the stress response (Romero and Wikelski 2002; Müllner et al. 2004).”
Biological effects, conservation potential, and research priorities of shark diving tourism. (2015, background): “…tourism can have sublethal physiological impacts on animals which can in turn impact important aspects of animal function such respiration, stress management, reproductive success, and body condition (e.g., McClung et al., 2004; Müllner et al., 2004; Bejder et al., 2006; Semeniuk et al., 2009).”
A multi‐tier approach to identifying environmental stress in altricial nestling birds (2005, neutral): “…to the latter hypothesis, stress responses may be beneficial for developing nestlings in spite of their parental dependence, and environmental stressors (Kitaysky et al. 2001a; Mullner et al. 2004), or withinbrood social interactions (e.g. Tarlow et al. 2001) may change glucocorticoid release.”
Costs of group-living for a normally solitary forager: effects of provisioning tourism on southern stingrays Dasyatis americana (2008, background): “…exhibit increased predator-avoidance energy expenditure, augmented circulating stress hormones, compromised immune function, reduced body condition, and decreased reproduction and survival of animals (Knight & Cole 1995, Ikuta & Blumstein 2003, Lusseau 2003, Müllner et al. 2004, Amo et al. 2006).”
Sex-specific consequences of life in the city (2007, background): “Studies exploring this important relationship have found varying, context-dependent relationships between cort levels and fitness components (Romero and Wikelski 2001; Clinchy et al. 2004; Mullner et al. 2004; Brown et al. 2005; Good et al. 2005; Meylan and Clobert 2005).”
Evaluating methods to quantify anthropogenic stressors on wild animals (2007, background): “Some populations or species seemingly habituate to increased disturbance (Ikuta and Blumstein, 2003) while others are sensitized to human activities (Blumstein, unpublished data; Müllner et al., 2004).”
Ski tourism affects habitat use and evokes a physiological stress response in capercaillie Tetrao urogallus: a new methodological approach (2007, background): “Juvenile hoatzins Opisthocomus hoazin living at ecotourist-exposed sites had a lower body mass and higher mortality and showed a stronger increase in corticosterone levels to experimental stress compared with individuals at undisturbed sites ( Mullner, Linsenmair & Wikelski 2004 ).”
Impact assessment research: use and misuse of habituation, sensitisation and tolerance in describing wildlife responses to anthropogenic stimuli (2009, background): “…that physiological evidence of a response could be detected in animals even when they exhibited little or no behavioural reaction or sign of disturbance (Moen et al. 1982, Culik et al. 1990, Wilson et al. 1991, Nimon et al. 1995, Regel & Putz 1997, Ratz & Thompson 1999, Müllner et al. 2004).”
