Future warming enhances rates of population increase of arthropod crop pests globally
Ecography, EarlyView.Arthropod herbivores cause severe crop yield losses worldwide. Global warming is expected to shift their ranges, phenologies and performances, highlighting the need for improved forecasts of their potential expansion and impacts on food security. After decades of experimental research on thermal biology of arthropod crop pests, available data and tools

PLoS ONE, 2016 It is well recognized that assemblage structure of stream macroinvertebrates changes with alterations in catchment or local land use. Our objective was to understand how the trophic ecology of benthic macroinvertebrate assemblages responds to land use ...

Ecography, EarlyView.Harmful Microcystis proliferation severely threatens aquatic ecosystems globally, but its impacts on food‐web stability remain poorly understood. Here, we analyzed 1309 metagenomic samples from freshwater ecosystems across China to investigate how Microcystis abundance affects synchrony among taxa in multi‐trophic food webs (from bacteriophages to ...

Fins are relevant non-lethal surrogates for muscle to measure stable isotopes in amphibians
Knowledge and Management of Aquatic Ecosystems, 2019 Stable isotope analyses (SIA) are now widely used in ecology research to quantify the trophic implications of a large range of ecological processes.

Ecography, EarlyView.Predator–prey interactions can trigger behavioural responses in ungulates, influencing their space‐use and foraging behaviour and, in turn, indirectly affecting browsing pressure. Changes in browsing pressure can affect plant recruitment and species composition, shaping forest regeneration through predator‐mediated trophic cascades.

Effects of climate on size structure and functioning of aquatic food webs [PDF]
, 2010 In aquatic food webs, the role of body size is notoriously strong. It is also well known that temperature has an effect on body size. For instance, Bergmann’s rule states that body size increases from warm to cold climates.

Environmental Policy and Governance, EarlyView.ABSTRACT This study uses the policy regime framework to examine how background conditions, institutions, and actor configurations shaped hunting rights within the forest–wildlife policy domain during Slovenia's postsocialist transformation. Drawing on media analysis, in‐depth interviews with policymakers, and legislative documents, it conducts a ...

The Living World in the curriculum: ecology, an essential part of biology learning [PDF]
, 2012 Argues that biology should be learnt in the living world not in the classroom. Field ecological education is essential. Ecology is ideal candidate for implementing proposed transformations in science curricula.
