Data from: Coarse dark patterning functionally constrains adaptive shifts from aposematism to crypsis in strawberry poison frogs

, 2014
Ecological specialization often requires tight co-evolution of several traits, which may constrain future evolutionary pathways and make species more prone to extinction.

Phylogeography and the evolution of correlated traits under multiple origins of aposematism in the poison frog family [PDF]

, 2009
textLiving organisms are under selection not only for one, but also for several inheritable characters at the same time. Well-sampled and well-supported phylogenies are necessary for the studies of character evolution and their history.

Acoustic Aposematism and Evasive Action in Select Chemically Defended Arctiine (Lepidoptera: Erebidae) Species: Nonchalant or Not?

, 2016
Tiger moths (Erebidae: Arctiinae) have experienced intense selective pressure from echolocating, insectivorous bats for over 65 million years. One outcome has been the evolution of acoustic signals that advertise the presence of toxins sequestered from ...

Beware glowing cadavers: bioluminescence of nematode symbiont Photorhabdus protects nematode-infected host cadavers from nocturnal scavengers

Frontiers in Ecology and Evolution
Photorhabdus spp. are the only known terrestrial bioluminescent bacteria. We show that the bioluminescence produced by these bacteria reduces scavenging activity on the insect cadavers they colonize. Photorhabdus spp.

Phenotypic and molecular variation in the green and black poison-dart frog Dendrobates auratus (Anura: Dendrobatidae) from Costa Rica

Revista de Biología Tropical, 2009
The green and black poison-dart frog Dendrobates auratus exhibits high intraspecific variation in hue color and pattern throughout its range, making it a very popular species in the pet trade.

The role of habitat heterogeneity on signal evolution in predator–prey interactions, with implications for the evolution of crypsis and aposematism

, 2015
Little is known about mechanisms promoting the diversity of antipredation strategies found in nature. In this study I explore how habitat heterogeneity may have profound effects on predator–prey communication.

Dietary conservatism may facilitate the initial evolution of aposematism

, 2003
It has generally been assumed that warningly coloured organisms pay a cost associated with their increased visibility, because naïve predators notice and eat them. This cost is offset by their enhanced protection from educated predators who associate the

Evolutionary and ecological dynamics of aposematism and mimicry in poison frogs [PDF]

, 2006
textIn aposematism, defended prey advertise their aversive qualities to predators using a warning signal. Predators that have learned the warning signal are thus the selective agent that can promote similarity in warning signals between distantly ...

Function of Vivid Coloration of Terrestrial Isopods from the Point of View of an Avian Predator

Insects
The ability of terrestrial isopods (Crustacea: Isopoda: Oniscidea) to protect themselves effectively from predation by birds has never been tested. They are equipped with glands producing chemical substances; moreover, some species show conspicuous ...
