Inducible chemical defences in animals [PDF]

open access: yesOikos, 2014
Phenotypic plasticity is extremely widespread in the behaviour, morphology and life‐history of animals. However, inducible changes in the production of defensive chemicals are described mostly in plants and surprisingly little is known about similar plasticity in chemical defences of animals. Inducible chemical defences may be common in animals because

Chemical defences against herbivores [PDF]

open access: yes, 2012
This chapter focuses on the recent and emerging research involving chemical defences against herbivory in aquatic primary producers. It provides an overview of plant chemical defence theories and highlights recent research on aquatic primary producers ...

Specificity in Mesograzer-Induced Defences in Seagrasses. [PDF]

open access: yesPLoS ONE, 2015
Grazing-induced plant defences that reduce palatability to herbivores are widespread in terrestrial plants and seaweeds, but they have not yet been reported in seagrasses. We investigated the ability of two seagrass species to induce defences in response

Comparing the Above and Below-Ground Chemical Defences of Three Rumex Species Between Their Native and Introduced Provenances. [PDF]

open access: yesJ Chem Ecol, 2023
Compared to their native range, non-native plants often experience reduced levels of herbivory in the introduced range. This may result in reduced pressure to produce chemical defences that act against herbivores.

Chemical antipredator defence is linked to higher extinction risk [PDF]

open access: yesRoyal Society Open Science, 2016
Many attributes of species may be linked to contemporary extinction risk, though some such traits remain untested despite suggestions that they may be important.

Chemical defences indicate bold colour patterns with reduced variability in aposematic nudibranchs. [PDF]

open access: yesProc Biol Sci
The selective factors that shape phenotypic diversity in prey communities with aposematic animals are diverse and coincide with similar diversity in the strength of underlying secondary defences.

Leaf chemical defences and insect herbivory in oak: accounting for canopy position unravels marked genetic relatedness effects. [PDF]

open access: yesAnn Bot, 2020
*Background and Aims Highly controlled experiments document that plant genetic diversity and relatedness can shape herbivore communities and patterns of herbivory. Evidence from the field is, however. scarce and inconsistent.

Beetle bombing always deters praying mantises [PDF]

open access: yesPeerJ, 2021
Some animals have evolved chemical weapons to deter predators. Bombardier beetles (Coleoptera: Carabidae: Brachininae: Brachinini) can eject toxic chemicals at temperatures of 100 °C from the tips of their abdomens, ‘bombing’ the attackers. Although some

Investment in seed physical defence is associated with species' light requirement for regeneration and seed persistence: evidence from Macaranga species in Borneo. [PDF]

open access: yesPLoS ONE, 2014
The seed stage is often critical in determining the regeneration success of plants. Seeds must survive an array of seed predators and pathogens and germinate under conditions favourable for seedling establishment.

Bombardiers and assassins: mimetic interactions between unequally defended insects [PDF]

open access: yesPeerJ, 2023
In defensive mimicry, resemblance between unequally defended species can be parasitic; this phenomenon has been termed quasi-Batesian mimicry. Few studies have used real co-mimics and their predators to test whether the mimetic interactions were ...
