Beetles “in red”: are the endangered flat bark beetles Cucujus cinnaberinus and C. haematodes chemically protected? (Coleoptera: Cucujidae)

open access: yesThe European Zoological Journal, 2018
Two native species of the genus Cucujus show a wide geographic distribution in Europe, Cucujus cinnaberinus (Scopoli, 1763) and C. haematodes Erichson, 1845.

Models of aposematism and the role of aversive learning [PDF]

open access: yes
The majority of species are under predatory risk in their natural habitat and targeted by predators as part of the food web. Through the process of evolution by natural selection manifold mechanisms have emerged to avoid predation.

A role for phenotypic plasticity in the evolution of aposematism [PDF]

open access: yesProceedings of the Royal Society of London. Series B: Biological Sciences, 2002
The evolution of warning coloration (aposematism) has been difficult to explain because rare conspicuous mutants should suffer a higher cost of discovery by predators relative to the cryptic majority, while at frequencies too low to facilitate predator aversion learning.

Defensive behaviors of Leptodactylus rhodomystax (Anura: Leptodactylidae) from northern Brazil [PDF]

open access: yes, 2023
The study of defensive behaviors in anurans can lead to new hypotheses for a better understanding of prey-predator interactions. Herein, based on field observations, we described for the first time defensive behaviors of Leptodactylus rhodomystax.

Colors and Some Morphological Traits as Defensive Mechanisms in Anurans

open access: yesInternational Journal of Zoology, 2009
Anurans may be brightly colored or completely cryptic. Generally, in the former situation, we are dealing with aposematism, and the latter is an example of camouflage.

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

open access: yesFrontiers 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

open access: yesRevista 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 control effect of bionic sticky traps on Apolygus lucorum in pear orchards in Taigu District

open access: yesGuoshu xuebao
【Objective】Apolygus lucorum is a major polyphagous pest in pear orchards, causing severe damage to young fruits and reducing their commercial value. Since the 2000s, its occurrence and damage have progressively intensified, as the last-generation adults ...

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

open access: yes, 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 ...
