Loss, persistence and reversal of phenotypic traits

open access: yesBiological Reviews, EarlyView.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

Kin discrimination in plants: overview and implications for population and community ecology

open access: yesBiological Reviews, EarlyView.
ABSTRACT Following the discovery of identity discrimination, particularly self and kin discrimination amongst plant competitors, research on interplant interactions has advanced significantly within plant physiology and evolutionary ecology. This review synthesizes current knowledge on how both self and kin discrimination influence plant growth ...

A New Vista of Opportunity in Diabetes Management: Natural Product‐Based β‐cell Preservation

open access: yesFood Chemistry International, EarlyView.
Preserving functional β‐cells via natural products offers promising strategy for diabetes treatment. ABSTRACT A defining characteristic of diabetes is β‐cell failure, in which β‐cells cannot modulate insulin secretion to compensate for escalating insulin resistance, pushing forward disease development.
