Climate affects neighbour-induced changes in leaf chemical defences and tree diversity-herbivory relationships. [PDF]
Funct Ecol, 2021 1. Associational resistance theory predicts that insect herbivory decreases with increasing tree diversity in forest ecosystems. However, the generality of this effect and its underlying mechanisms are still debated, particularly since evidence has ...

Beetle bombing always deters praying mantises [PDF]
PeerJ, 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

Induced chemical defences in Colophospermum mopane trees
African Journal of Range & Forage Science, 2007 A field experiment was conducted in which Mopane (Colophospermum mopane) trees were subjected to three different canopy treatments:felling of trees at a mean height of 0.7m above ground level, felling at a height of 2m, or pruning of selected branches.

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

Seaweed Invasions and Novel Chemical Defences
, 2012 Biological invasions pose a risk to the biodiversity and the functioning of ecosystems in invaded areas. The reasons why some introduced species become dominant and widespread in their new environments is still largely an unsettled question. It has commonly been predicted that introduced plants will invade when they are less affected by herbivores ...

, 2021 A long-standing paradigm in ecology holds that herbivore pressure and thus plant defences increase towards lower latitudes. However, recent work has challenged this prediction where studies have found no relationship or opposite trends where herbivory or

Species with a chemical defence, but not chemical offence, live longer [PDF]
Journal of Evolutionary Biology, 2013 AbstractEvolutionary hypotheses for ageing generally predict that delayed senescence should evolve in organisms that experience lower extrinsic mortality. Thus, one might expect species that are highly toxic or venomous (i.e. chemically protected) will have longer lifespans than related species that are not likewise protected.

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

Do induced responses mediate the ecological interactions between the specialist herbivores and phytopathogens of an alpine plant? [PDF]
PLoS ONE, 2011 Plants are not passive victims of the myriad attackers that rely on them for nutrition. They have a suite of physical and chemical defences, and are even able to take advantage of the enemies of their enemies.
