Defence mitigation by predators of chemically defended prey integrated over the predation sequence and across biological levels with a focus on cardiotonic steroids

Royal Society Open Science, 2022
Predator–prey interactions have long served as models for the investigation of adaptation and fitness in natural environments. Anti-predator defences such as mimicry and camouflage provide some of the best examples of evolution.

Quo vadis Cardiac Glycoside Research?

Toxins, 2021
Cardiac glycosides (CGs), toxins well-known for numerous human and cattle poisoning, are natural compounds, the biosynthesis of which occurs in various plants and animals as a self-protective mechanism to prevent grazing and predation.

Molecular Modes of Action of an Aqueous Nerium oleander Extract in Cancer Cells In Vitro and In Vivo

Molecules, 2023
Cancer drug resistance remains a major obstacle in clinical oncology. As most anticancer drugs are of natural origin, we investigated the anticancer potential of a standardized cold-water leaf extract from Nerium oleander L., termed Breastin.

Cardenolides, induced responses, and interactions between above? and belowground herbivores of milkweed (Asclepias spp.) [PDF]

, 2009
Theory has long predicted allocation patterns for plant defense against herbivory, but only recently have both above? and belowground plant defenses been considered simultaneously.

Independent evolution of ancestral and novel defenses in a genus of toxic plants (Erysimum, Brassicaceae)

eLife, 2020
Phytochemical diversity is thought to result from coevolutionary cycles as specialization in herbivores imposes diversifying selection on plant chemical defenses.

Unraveling the roles of genotype and environment in the expression of plant defense phenotypes

Ecology and Evolution, 2021
Phenotypic variability results from interactions between genotype and environment and is a major driver of ecological and evolutionary interactions. Measuring the relative contributions of genetic variation, the environment, and their interaction to ...
