Rapid Shifts in Visible Carolina Grasshopper (Dissosteira carolina) Coloration During Flights
Frontiers in Ecology and Evolution, 2022 Some brightly colored structures are only visible when organisms are moving, such as parts of wings that are only visible in flight. For example, the primarily brown Carolina grasshopper (Dissosteira carolina) has contrasting black-and-cream hindwings ...

Camouflaging moving objects: crypsis and masquerade [PDF]
Behavioral Ecology, 2017 Motion is generally assumed to "break" camouflage. However, although camouflage cannot conceal a group of moving animals, it may impair a predator's ability to single one out for attack, even if that discrimination is not based on a color difference. Here, we use a computer-based task in which humans had to detect the odd one out among moving objects ...

Cuttlefish color change as an emerging proxy for ecotoxicology
Frontiers in Physiology, 2023 Lately, behavioral ecotoxicology has flourished because of increasing standardization of analyses of endpoints like movement. However, research tends to focus on a few model species, which limits possibilities of extrapolating and predicting ...

Lizard colour plasticity tracks background seasonal changes
Biology Open, 2020 Environmental heterogeneity on a spatial and temporal scale fosters an organism's capacity to plastically alter coloration. Predation risk might favour the evolution of phenotypic plasticity in colour patterns, as individuals who change colour throughout

Tests of search image and learning in the wild: Insights from sexual conflict in damselflies
Ecology and Evolution, 2021 Search image formation, a proximal mechanism to maintain genetic polymorphisms by negative frequency‐dependent selection, has rarely been tested under natural conditions.

Ecology and Evolution, 2020 Cryptic coloration is an adaptative defensive mechanism against predators. Color patterns can become cryptic through background coloration‐matching and disruptive coloration.

Brazilian Journal of Biology, 2023 A little-studied characteristic of the Mexican native fish Dormitator latifrons is the effect that the color of the bottom or lining of ponds or tubs can have on their growth and blood parameters under controlled conditions.

Roosting ecology and the evolution of pelage markings in bats. [PDF]
PLoS ONE, 2011 Multiple lineages of bats have evolved striking facial and body pelage makings, including spots, stripes and countershading. Although researchers have hypothesized that these markings mainly evolved for crypsis, this idea has never been tested in a ...

Camouflage and Exploratory Avoidance of Newborn Cuttlefish under Warming and Acidification
Biology, 2022 Ocean warming and acidification have been shown to elicit deleterious effects on cephalopod mollusks, especially during early ontogeny, albeit effects on behavior remain largely unexplored.
