Sexual differences in defensive strategies: investigating chemical defences and visual signals in a wasp moth Amata nigriceps [PDF]
Royal Society Open ScienceAposematic animals use conspicuous warning signals to advertise their chemical defences to predators. Selection by predators can favour conspicuousness and large pattern elements, which enhance predator avoidance learning.

Exposure to Batrachochytrium dendrobatidis affects chemical defences in two anuran amphibians, Rana dalmatina and Bufo bufo [PDF]
BMC Ecology and Evolution, 2021 Background Batrachochytrium dendrobatidis (Bd) is the causative agent of chytridiomycosis, one of the major causes of worldwide amphibian biodiversity loss.

Toxicity and Taste: Unequal Chemical Defences in a Mimicry Ring [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2018 Mimicry of warning signals is common, and can be mutualistic when mimetic species harbour equal levels of defence (Müllerian), or parasitic when mimics are undefended but still gain protection from their resemblance to the model (Batesian). However, whether chemically defended mimics should be similar in terms of toxicity (i.e.

Age- and environment-dependent changes in chemical defences of larval and post-metamorphic toads [PDF]
BMC Evolutionary Biology, 2017 Background Chemical defences are widespread in animals, but how their production is adjusted to ecological conditions is poorly known. Optimal defence theory predicts that inducible defences are favoured over constitutive defences when toxin production ...

Resin acids as inducible chemical defences of pine seedlings against chewing insects. [PDF]
PLoS ONE, 2020 Inducibility of defences in response to biotic stimuli is considered an important trait in plant resistance. In conifers, previous research has mostly focused on the inducibility of the volatile fraction of the oleoresin (mono- and sesquiterpenes ...

Plant domestication decreases both constitutive and induced chemical defences by direct selection against defensive traits [PDF]
Scientific Reports, 2018 Studies reporting domestication effects on plant defences have focused on constitutive, but not on induced defences. However, theory predicts a trade-off between constitutive (CD) and induced defences (ID), which intrinsically links both defensive ...

Small prey fight back: post-capture defences shape prey–predator size relationships [PDF]
Scientific ReportsSize relationships between prey and predators are a key topic in ecology. A positive correlation often exists between the sizes of prey and predators. Although predators can consume much smaller prey, some preferentially target larger prey and avoid very

Simple growth patterns can create complex trajectories for the ontogeny of constitutive chemical defences in seaweeds. [PDF]
PLoS ONE, 2014 All of the theory and most of the data on the ecology and evolution of chemical defences derive from terrestrial plants, which have considerable capacity for internal movement of resources.
