Stable pollination service in a generalist high Arctic community despite the warming climate. [PDF]
Abstract Insects provide key pollination services in most terrestrial biomes, but this service depends on a multistep interaction between insect and plant. An insect needs to visit a flower, receive pollen from the anthers, move to another conspecific flower, and finally deposit the pollen on a receptive stigma.

Microbe-induced resistance involves priming of direct or indirect defenses according to the stage of herbivory. [PDF]
Summary Microbe‐induced resistance (MIR) encompasses a broad range of plant responses that mediate both direct and indirect defenses against herbivores. However, previous studies have addressed MIR in relation to either direct or indirect defenses in isolation, overlooking potential conflicts or synergies that may arise between MIR‐elicited defense ...

Anomalous latitudinal gradients in parasitoid wasp diversity-Hotspots in regions with larger temperature range. [PDF]
Using the largest georeferenced molecular dataset for ichneumonoid parasitoid wasps, we implemented a macrogenetics approach to examine latitudinal patterns and predictors of intraspecific genetic diversity and explain the global distribution of genetic diversity in this group.

Abstract Aim Mining is increasingly pressuring areas of critical importance for biodiversity conservation, such as the Brazilian Amazon. Biodiversity data are limited in the tropics, restricting the scope for risks to be appropriately estimated before mineral licensing decisions are made.

Abstract Understanding the evolution of genitalic traits and their co‐evolution between sexes is at the core of Evolutionary Biology. Cross‐species reproductive trait co‐variation can be the outcome of hybrid avoidance and/or sexual selection. Although the outcome of these two phenomena will look similar, they yield distinct patterns of species co ...

Agroecological management produced spatial and temporal gradients in crop and non‐crop floral resources that interacted to modify pollinator or seed herbivore–parasitoid interactions and Cyanus segetum and Centaurea jacea seed set. The degree of phenological overlap between C. segetum and C.

Read the free Plain Language Summary for this article on the Journal blog. Abstract When feeding on a plant, herbivorous insects alter the quality of the plant as a food source. This affects other organisms interacting with the same plant. These so‐called ‘plant‐mediated interactions’ can be altered by parasitoids that attack the herbivores.

Cacao flower visitation: Low pollen deposition, low fruit set and dominance of herbivores
Pollination of native cacao is surprisingly understudied, even though the process is crucial for the global chocolate production. In an understudied peruvian region, we found herbivores as dominant flower visitors, and low pollen deposition.Fruit set was low when flowers were pollinated naturally (2%), but also manually (7%). Our findings highlight the

Comparing diversity patterns in the arthropod communities of sprayed and unsprayed oak canopies, our results show that selective insecticides can alter species diversity in presumably non‐sensitive taxa. Even though the ecological significance of these impacts has yet to be assessed in an operational setting, their existence calls for increased ...

Our findings highlight the need for conservation biological control to go beyond ‘one size fits all’ and consider the specific ecology of the involved organisms, even for a single crop type. Landscapes with high edge density and flowering woody plants may support natural enemies, in particular syrphids, which colonised the fields early in the season ...
