Changes in oak (Quercus robur) photosynthesis after winter moth (Operophtera brumata) herbivory are not explained by changes in chemical or structural leaf traits [PDF]

open access: yes, 2020
Insect herbivores have the potential to change both physical and chemical traits of their host plant. Although the impacts of herbivores on their hosts have been widely studied, experiments assessing changes in multiple leaf traits or functions ...

Arbuscular mycorrhizal fungi prevent the negative effect of drought and modulate the growth‐defence trade‐off in tomato plants

open access: yesJournal of Sustainable Agriculture and Environment, 2022
Introduction A wide range of arbuscular mycorrhizal fungi (AMF) can be applied to agricultural soils as biofertilizers for increasing crop growth and yield.

Tree defence and bark beetles in a drying world: carbon partitioning, functioning and modelling. [PDF]

open access: yes, 2020
Drought has promoted large-scale, insect-induced tree mortality in recent years, with severe consequences for ecosystem function, atmospheric processes, sustainable resources and global biogeochemical cycles.

Chemical Defence and Toxins of Plants [PDF]

open access: yes, 2010
Higher plants protect themselves by producing a variety of secondary metabolites and proteins that are involved in defense against herbivores as well as microbial pathogens. Concerning microbial pathogenesis in plants, in many cases, it is known that phytotoxins that are produced by plant pathogens play an important role in disease development causing ...

Predator‐induced changes in the chemical defence of a vertebrate [PDF]

open access: yesJournal of Animal Ecology, 2019
Abstract1. Inducible defences are ubiquitous in the animal kingdom, but little is known about facultative changes in chemical defences in response to predators, especially so in vertebrates.2. We tested for predator‐induced changes in toxin production of larval common toads (Bufo bufo), which are known to synthesize bufadienolide compounds.3.

Plant stages with biotic, indirect defences are more palatable and suffer less herbivory than their undefended counterparts [PDF]

open access: yes, 2010
Plants have evolved several anti-herbivory strategies, including direct defences, such as mechanical and chemical defences, and indirect or biotic defences, such as the recruitment of defending animals.

Opisthobranch grazing results in mobilisation of spherulous cells and re-allocation of secondary metabolites in the sponge Aplysina aerophoba

open access: yesScientific Reports, 2020
Sponges thrive in marine benthic communities due to their specific and diverse chemical arsenal against predators and competitors. Yet, some animals specifically overcome these defences and use sponges as food and home.

Evolutionarily stable defence and signalling of that defence [PDF]

open access: yes, 2006
We examine the evolution and maintenance of defence and conspicuousness in prey species using a game theoretic model. In contrast to previous works, predators can raise as well as lower their attack probabilities as a consequence of encountering ...

A theory for investment across defences triggered at different stages of a predator-prey encounter [PDF]

open access: yes, 2019
We introduce a general theoretical description of a combination of defences acting sequentially at different stages in the predatory sequence in order to make predictions about how animal prey should best allocate investment across different defensive ...
