Post-attack aposematic display in prey facilitates predator avoidance learning

open access: yesFrontiers in Ecology and Evolution, 2016
Warning signals protect unpalatable prey from predation because predators who learn the association between the warning signal and prey unprofitability decrease attacks on the prey.

Colour change and colour phases in Lethrinidae with insights into ecology

open access: yesEcology and Evolution, 2023
Colour change is used by a wide range of animals. It is used for intra‐ and interspecific communication and crypsis, and can occur on morphological and physiological levels.

Morphological and Ontogenetic Skin Color Changes in the American Alligator (Alligator mississippiensis)

open access: yesAnimals, 2023
To assess skin color change in alligators, we maintained animals in differently lighted environments and also measured skin colors in an ontogenetic series of wild animals. Juvenile alligators maintained in black enclosures exhibited a gradual lightening

Camouflaged and Watchful: Stonefish Escape Behavior on Crowded Reefs

open access: yesJournal of Marine Science and Engineering
Understanding escape behavior in cryptic and venomous reef fishes is critical for both ecological theory and public safety in coastal environments. We quantified the Flight Initiation Distance (FID) of 65 individual stonefish (Synanceia spp.) across four

Age and Appearance Shape Behavioral Responses of Phasmids in a Dynamic Environment

open access: yesFrontiers in Ecology and Evolution, 2022
Although morphological adaptations leading to crypsis or mimicry have been studied extensively, their interaction with particular behaviors to avoid detection or recognition is understudied.

The art of avoidance: bedsite use, antipredator strategies, and predation risk in white‐tailed deer fawns

open access: yesThe Journal of Wildlife Management, EarlyView.
Horizontal visibility, rather than concealment cover, drove fawn bedsite use and predation risk. Greater field of view decreased the odds of coyote predation, likely by facilitated by early detection. As fawns transitioned from hiders to followers, they shifted from using dense overstory concealment to more open overstory that favored improved escape ...

Effect of age class on the survivorship and spatial movement patterns of headstarted Texas horned lizards soft‐released into an urban population

open access: yesThe Journal of Wildlife Management, EarlyView.
When compared to resident lizards of the corresponding age class, juvenile headstarted Texas horned lizards soft‐released into an urban population exhibited more favorable responses to short‐term translocation objectives (i.e., daily movement rates, home range sizes, and survival rates) than did conspecifics headstarted to the adult age class ...

Shell color polymorphism in marine gastropods

open access: yesEvolutionary Applications, 2023
Marine gastropods are characterized by an incredible variation in shell color. In this review, we aim to introduce researchers to previous studies of shell color polymorphism in this group of animals, trying to provide an overview of the topic and ...

Fine‐scale spatial variation in eastern grey squirrel melanism across a complex urban landscape

open access: yesJournal of Animal Ecology, EarlyView.
By sampling 197 parks, the study demonstrates how natural geography creates divergence within cities. The findings reveal that the St. Lawrence River and its tributaries act as barriers, disrupting urban melanism clines in grey squirrels. Ultimately, the research indicates that natural features still dictate evolutionary rules in anthropogenic ...

Continuous Variation in an Aposematic Pattern Affects Background Contrast, but Is Not Associated With Differences in Microhabitat Use

open access: yesFrontiers in Ecology and Evolution, 2022
Variation in aposematic signals was once predicted to be rare, yet in recent years it has become increasingly well documented. Despite increases in the frequency with which polytypism and polymorphism have been suggested to occur, population-wide ...
