Known Predators of Crown-of-Thorns Starfish (Acanthaster spp.) and Their Role in Mitigating, If Not Preventing, Population Outbreaks

open access: yesDiversity, 2017
Predatory release has long been considered a potential contributor to population outbreaks of crown-of-thorns starfish (CoTS; Acanthaster spp.). This has initiated extensive searches for potentially important predators that can consume large numbers of ...

Bombardier beetles repel invasive bullfrogs [PDF]

open access: yesPeerJ, 2022
Invasive non-native predators negatively affect native species; however, some native species can survive the predation pressures of invasive species by using pre-existing antipredator strategies or evolving defenses against invasive predators.

Grasses and the resource availability hypothesis: the importance of silica-based defences [PDF]

open access: yes, 2007
The resource availability hypothesis (RAH) predicts that allocation of resources to anti-herbivore defences differs between species according to their growth rate.

Cyanogenesis of wild lima bean (Phaseolus lunatus L.) is an efficient direct defence in nature. [PDF]

open access: yesPLoS ONE, 2009
In natural systems plants face a plethora of antagonists and thus have evolved multiple defence strategies. Lima bean (Phaseolus lunatus L.) is a model plant for studies of inducible indirect anti-herbivore defences including the production of volatile ...

The relationships between toad behaviour, antipredator defences, and spatial and sexual variation in predation pressure [PDF]

open access: yesPeerJ, 2022
Background Animal behaviour is under strong selection. Selection on behaviour, however, might not act in isolation from other fitness-related traits. Since predators represent outstanding selective forces, animal behaviour could covary with antipredator ...

Differential effects of jasmonic acid treatment of Brassica nigra on the attraction of pollinators, parasitoids, and butterflies [PDF]

open access: yes, 2008
Herbivore-induced plant defences influence the behaviour of herbivores as well as that of their natural enemies. Jasmonic acid is one of the key hormones involved in both these direct and indirect induced defences.

A typology of marine and estuarine hazards and risks as vectors of change : a review for vulnerable coasts and their management [PDF]

open access: yes, 2014
This paper illustrates a typology of 14 natural and anthropogenic hazards, the evidence for their causes and consequences for society and their role as vectors of change in estuaries, vulnerable coasts and marine areas.

CELLULAR RESPONSES TO DNA DAMAGE AND ONCOGENESIS BY THE p53 AND pRb/E2F PATHWAYS

open access: yesJournal of Dentistry Indonesia, 2015
Cellular responses to stress including DNA damage, show multiple options involving the mechanisms of growth arrest. DNA repair and programmed cell death or apoptosis. Failures in these mechanisms can result in oncogenesis or accelerated senescence.

The Role of Silicon in Antiherbivore Phytohormonal Signalling

open access: yesFrontiers in Plant Science, 2019
The role of plant silicon (Si) in the alleviation of abiotic and biotic stress is now widely recognised and researched. Amongst the biotic stresses, Si is known to increase resistance to herbivores through biomechanical and chemical mechanisms, although ...
