Insects in agroecosystems contend with many stressors–eg, chemicals, heat, nutrient
deprivation–that are often encountered at low levels. Exposure to mild stress is now well …

Abrupt ecological changes are, by definition, those that occur over short periods of time
relative to typical rates of change for a given ecosystem. The potential for such changes is …

Ecologists and farmers often have contrasting perceptions about the value of natural habitat
in agricultural production landscapes, which so far has been little acknowledged in ecology …

Increasing evidence suggests that land-use intensification contributes to destabilization of
trophic networks of insect communities in agriculture resulting in a loss of biodiversity …

Highlights•The timing of heat stress within host–parasitoid life cycles is critical.•Thermal
mismatch between hosts and parasitoids is common.•Heat tolerance of parasitoids can be …

When ecological and evolutionary dynamics occur on comparable timescales, persistence
of the ensuing eco-evolutionary dynamics requires both ecological and evolutionary …

In observational demographic data, the number of measured factors that could potentially
drive demography (such as daily weather records between two censuses) can easily exceed …

Vegetable production is a source of income for smallholder farmers in Limpopo Province,
South Africa. Vegetable production is constrained by the negative impacts of climate change …

Climate change is projected to increase the frequency and intensity of extreme heat events,
and may increase humidity levels, leading to coupled thermal and hydric stress. However …

Phytophagous insects evolving in agroecosystems express numerous defences when faced
with myriads of natural enemies. Such defensive traits might impair the effectiveness of …
