Evolutionary constraints in host shifts: Limited adaptation of Plutella xylostella to cardenolide‐defended Erysimum cheiranthoides

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Coevolutionary arms races between plants and insects, in which gains of novel plant defences select for counteradaptations in herbivores, are key drivers of biodiversity.

Mycorrhizae Alter Toxin Sequestration and Performance of Two Specialist Herbivores

Frontiers in Ecology and Evolution, 2018
Multitrophic species interactions are shaped by both top-down and bottom-up factors. Belowground symbionts of plants, such as arbuscular mycorrhizal fungi (AMF), can alter the strength of these forces by altering plant phenotype.

Chemical cues that attract cannibalistic cane toad (Rhinella marina) larvae to vulnerable embryos

Scientific Reports, 2021
Chemical cues produced by late-stage embryos of the cane toad (Rhinella marina) attract older conspecific larvae, which are highly cannibalistic and can consume an entire clutch.

Ouabain‐induced hypertension in rats: Mechanisms, variability and translational implications

Experimental Physiology, EarlyView.
Abstract Ouabain‐induced hypertension is a multifactorial and condition‐dependent phenomenon involving coordinated actions across vascular, renal and central nervous system pathways. At the vascular level, ouabain inhibits Na⁺/K⁺‐ATPase, particularly the α2‐isoform, leading to elevated intracellular Ca2⁺, enhanced vasoconstriction and structural ...

Cardiac glycosides and breast cancer risk: A systematic review and meta-analysis of observational studies [PDF]

, 2017
Cardiac glycosides are phytoestrogens and have been linked to the risk of estrogen sensitive cancers such as uterus cancer. However, the association between use of cardiac glycosides and risk of breast cancer remains unclear.
