Host defense triggers rapid adaptive radiation in experimentally evolving parasites

Evolution Letters, 2019
Adaptive radiation occurs when the members of a single lineage evolve different adaptive forms in response to selection imposed by competitors or predators.

Perch-height specific predation on tropical lizard clay models: implications for habitat selection in mainland neotropical lizards

Revista de Biología Tropical, 2009
Predation has been hypothesized to be a strong selective force structuring communities of tropical lizards. Comparisons of perch height and size-based predation frequencies can provide a unique window into understanding how predation might shape habitat ...

Can exosomes link the cellular and endocrine stress response? A test using the brown anole lizard (Anolis sagrei) as a model

Stress
Exosomes are nanoscale extracellular vesicles critical for intercellular communication, but their role in vertebrate stress responses remains unclear.

Escape tactics and effects of perch height and habituation on flight initiation distance in two Jamaican anoles (Squamata: Polychrotidae)

Revista de Biología Tropical, 2010
Escape by Anolis lizards is influenced by microhabitats and fight initiation distance increases with predation risk. Differences in microhabitat use among ecomorphs affect escape behavior, but only two studies have reported ecomorphological differences ...

The role of microhabitat in predation on females with alternative dorsal patterns in a small Costa Rican anole (Squamata: Dactyloidae)

Revista de Biología Tropical, 2013
Predation is one of the major selective agents influencing evolution of color patterns. Cryptic color patterns decrease detection probability by predators, but their concealing function depends on the background against which patterns are seen; therefore,
