Invader danger: Lizards faced with novel predators exhibit an altered behavioral response to stress
Stress and success: Individual differences in the glucocorticoid stress response predict behavior and reproductive success under high predation risk
Naïveté in novel ecological interactions: lessons from theory and experimental evidence
  • A. Carthey, P. Banks
  • Environmental Science
    Biological reviews of the Cambridge Philosophical Society
  • 2014
TLDR
This review critically review both classic and current theory relating to predator–prey interactions between both predators and prey with shared evolutionary histories, and those that are ecologically ‘mismatched’ through the outcomes of biological invasions.
Wet- and Dry-Season Steroid Hormone Profiles and Stress Reactivity of an Insular Dwarf Snake, the Hog Island Boa (Boa constrictor imperator)
TLDR
Factors associated with the sex steroid hormone concentrations and adrenocortical response to capture stress in Hog Island boas in the Cayos Cochinos archipelago of Honduras are explored to generate comparative field hormone data from a tropical reptile and test the island tameness hypothesis.
Common myths of glucocorticoid function in ecology and conservation.
  • L. Romero, U. Beattie
  • Biology
    Journal of experimental zoology. Part A, Ecological and integrative physiology
  • 2021
TLDR
Five common assumptions often made about glucocorticoids in ecological and conservation research that are not generally supported by the literature are discussed and proper consideration of these common assumptions will greatly aid in interpreting glucoc Corticoid data from ecological and Conservation studies.
Competitive naïveté between a highly successful invader and a functionally similar native species
TLDR
Black rats investigated bush rat odors but not vice versa, suggesting that bush rats may remain naïve towards their new competitor, suggesting highly successful invaders such as black rats may possess traits such as broad recognition templates and rapid learning capabilities that contribute to their ongoing success in invading new environments.
The Role of Animal Cognition in Human-Wildlife Interactions
TLDR
The cues that wild animals use to modulate their behavioral responses toward humans, such as human facial features and gaze direction are examined, and how the cognitive abilities of wild animals are likely to be under selection by humans and therefore influence population and community composition is considered.
Utility of biological sensor tags in animal conservation
TLDR
This approach can measure (in real time) the state of free-ranging animals and thus provide managers with objective, timely, relevant, and accurate data to inform policy and decision making.
Analysis of threats to Galápagos Marine Iguanas (Amblyrhynchus cristatus)

Non‐invasive measurement of metabolic rates in wild, free‐living birds using doubly labelled water
TLDR
This paper aims to demonstrate the efforts towards in-situ applicability of EMMARM, which aims to provide real-time information about the behaviour of birds of prey in the DST-NRF area.

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.
Behavioral and physiological adjustments to new predators in an endemic island species, the Galápagos marine iguana
Corticosterone levels predict survival probabilities of Galápagos marine iguanas during El Niño events

TLDR
The results lend support to the use of corticosterone as a rapid quantitative predictor of survival in wild animal populations and predicted overall population health during the 1998 El Niño famine and the 1999 La Niña feast period.
Stress response during development predicts fitness in a wild, long lived vertebrate
TLDR
It is shown that the magnitude of the adrenocortical response to a standardized perturbation during development is negatively related to survival and recruitment in a wild population of long lived birds, providing empirical evidence for a link between stress response, not exposure to stressors, and fitness in a vertebrate under natural conditions.
The role of introduced species in shaping the distribution and abundance of island reptiles
TLDR
It is shown that present day competition and predation are potent forces shaping community structure and geographic distributions, and the role played by coevolution in mediating interactions between competitors and predator and prey is highlighted.
THE ROLE OF INTRODUCED SPECIES IN THE DEGRADATION OF ISLAND ECOSYSTEMS: A Case History of Guam1
TLDR
There were important interactions among these factors, especially the presence of introduced prey that were thus able to maintain their populations and provide alternate prey to the introduced predator while it was driving the native prey species to extinction.
Effects of predator training on behavior and post-release survival of captive prairie dogs (Cynomys ludovicianus)
Captive European Starlings (Sturnus vulgaris) in Breeding Condition Show an Increased Cardiovascular Stress Response to Intruders
TLDR
Male starlings in breeding condition, therefore, demonstrate an increased sensitivity to additional conspecifics, suggesting that a higher tolerance for intrusion may facilitate flocking behavior, while a lower tolerance may aid in territoriality.
Teaching an endangered mammal to recognise predators
Training Captive‐Bred or Translocated Animals to Avoid Predators
TLDR
It is concluded that pre-release training has the potential to enhance the expression of preexisting antipredator behavior, and potential training techniques involve classical conditioning procedures in which animals learn that model predators are predictors of aversive events.
