Tameness and stress physiology in a predator-naive island species confronted with novel predation threat
TLDR
The ability of marine iguanas to cope with predator introductions is limited by narrow reaction norms for behavioural wariness rather than by constraints in the underlying physiological stress system, which predicts that island endemics show flexible physiological stress responses but are restricted by narrow behavioural plasticity.
Island tameness: An altered cardiovascular stress response in Galápagos marine iguanas
Geographic Variation of Movement and Display Behavior of Side-blotched Lizards (Uta stansburiana) Related to Predation Environment
TLDR
It is suggested that conspicuous behavior in lizards is reduced in the face of increased predation pressure but that variation among populations may obscure this pattern.
Predator exposure alters stress physiology in guppies across timescales
REDUCED ESCAPE RESPONSES AND MORPHOLOGICAL AND PHYSIOLOGICAL ANTIPREDATORY ADAPTATIONS RELATED TO ESCAPE IN LIZARDS
Observers of wildlife on oceanic islands where natural predators and human beings have been scarce or absent for long intervals often have reported that wariness is greatly reduced or absent.…
Predator loss leads to reduced antipredator behaviours in Bahamas mosquitofish
TLDR
Tests performed with laboratory-raised mosquitofish revealed genetic variation for these antipredator behaviours, and their responses largely mirrored those of wild-caught fish from their blue hole even after two laboratory generations without any predator exposure.
Presence of mammalian predators decreases tolerance to human disturbance in a breeding shorebird
TLDR
It is found that flushing distances were increased at sites where mammalian predators were present and decreased where exposure to humans was high, and these effects were additive, and are interpreted as the effects of generalization and habituation, respectively.
Evolution of antipredator behavior in an island lizard species, Podarcis erhardii (Reptilia: Lacertidae): The sum of all fears?
TLDR
Examination of antipredator behaviors in Aegean wall lizards across an archipelago of land‐bridge islands that vary in predator diversity and period of isolation revealed that flight initiation distance decreased with increased duration of isolation in addition to the effects of current predator Diversity, whereas tail autotomy could be explained simply by current predator diversity.
Stress hormones mediate predator-induced phenotypic plasticity in amphibian tadpoles
TLDR
The hypothesis that tadpole physiological and behavioural/morphological responses to predation are causally interrelated is supported, as well as the mechanistic link to anti-predator defences in Rana sylvatica tadpoles.

Isolation from mammalian predators differentially affects two congeners
TLDR
It is hypothesize that the presence of a single predator, even if it is active at a different time of day, may profoundly affect the way a species responds to the loss of other predators by maintaining certain antipredator behaviors.
Effects of sex, body size, temperature, and location on the antipredator tactics of free-ranging gartersnakes (Thamnophis sirtalis, Colubridae)
TLDR
The results differ from those of previous studies and suggest that antipredator responses in these animals depend in a flexible and complex way upon biotic and abiotic variables.
An invasive species induces rapid adaptive change in a native predator: cane toads and black snakes in Australia
  • B. Phillips, R. Shine
  • Environmental Science
    Proceedings of the Royal Society B: Biological Sciences
  • 2006
TLDR
The results strongly suggest that black snake behaviour and physiology have evolved in response to the presence of toads, and have done so rapidly.
Temporal pattern of foraging and microhabitat use by Galápagos marine iguanas, Amblyrhynchus cristatus
TLDR
It is suggested that size-ordered differences in marine iguana thermoregulatory behavior reflect underlying ontogenetic changes in costs and benefits of thermoreGulation due to differences in predator pressure, quantity of food and electrolytes taken at each feeding, mode of foraging, and agonistic tendencies.
Recolonizing Carnivores and Naïve Prey: Conservation Lessons from Pleistocene Extinctions
TLDR
The fact that at least one prey species quickly learns to be wary of restored carnivores should negate fears about localized prey extinction.
Ecological factors influencing the antipredator behaviors of the ground skink, Scincella lateralis
TLDR
In the laboratory, S. lattraUs did not alter flight responses based on the availability of cover objects or tail condition of the lizards, and the thennoregulatory strategy of ground skinks closely parallels theoretical predictions for forest-dwelling lizards based on optimum performance curves.
Seasonal changes of the adrenocortical response to stress in birds of the Sonoran Desert.
TLDR
Analysis of plasma levels from black-throated sparrows, cactus wrens, and curve-billed thrashers indicated that at least some birds breeding in the open desert with restricted access to water are able to suppress the classical adrenocortical response to stress, and it is possible that this stress modulation may allow breeding to continue despite severe heat.
To run or hide? Age-dependent escape behaviour in the common flat lizard (Platysaurus intermedius wilhelmi)
TLDR
It is suggested that because a greater suite of predators feed on small juvenile lizards, this may affect their choice of refuge and result in the avoidance of crevices when chased.
Physiological and Behavioral Differences in Magellanic Penguin Chicks in Undisturbed and Tourist‐Visited Locations of a Colony
TLDR
The results show that the coupling of behavioral and physiological habituation in Magellanic Penguins is complex and life‐history context may greatly affect the ability of wildlife to adapt to anthropogenic disturbances.
