Does a shift to a novel host plant create a defence‐free space for a specialist herbivore species?

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract While host switches can promote speciation in herbivorous insects, the benefits of switching hosts have only been ascribed to escaping competition and natural enemies. Herbivores might also escape from the defences of their ancestral host if their new host species lacks

An epigenomic threshold hypothesis for integrating dynamic environmental signals into functional models of developmental polyphenisms

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Interactions between developing embryos and a multitude of environmental factors (e.g. climate, nutrition, social cues, stress and anthropogenic contaminants) underlie adaptive and non‐adaptive developmental plasticity and carry broad implications across ecological ...

New genetic resources for aphid resistance were identified from a newly developed wheat mutant library

open access: yesHeliyon
Reports on development of resilient wheat mutants to aphid infestation—causing heavy losses to wheat production in many parts of the world, are scanty. The present study aimed to identify genetic diversity of wheat mutants in terms of varying degree of ...

From cities to refuges for pollinators: Urban practices for enhancing pollinator habitats in changing landscapes

open access: yesJournal of Applied Ecology, EarlyView.
A framework for the support of pollinators in urban areas is developed here, based on five pillars: nesting, flower resources, artificial support, management and society acceptance, with additional key elements from science and society. Society should incorporate strategies for pollinators as in this framework by means of co‐planning with stakeholders,

Sub-lethal effect of combination of Metarhizium anisopliae and imidacloprid on life table of Myzus persicae (Hem.: Aphididae)

open access: yesJournal of Crop Protection, 2015
The sub-lethal effect of Metarhizium anisopliae and imidacloprid as well as combination of the two control agents was examined on life table parameters of Myzus persicae on different cultivars of canola under laboratory condition at 25 ± 1 ºC, 85% RH and
