ABSTRACT Aim To describe and compare the diets of an Arctic‐breeding shorebird, the Red Knot (Calidris canutus), across three geographically distinct breeding sites. We aimed to document the dietary patterns and identify key prey groups that characterise each population's foraging ecology.

Effects of flower patch additions and urbanisation on cavity‐nesting bees and wasps
Urbanisation can negatively affect cavity‐nesting bees and wasps, yet common conservation interventions such as flower patches and artificial nests lack strong empirical support. In a 2‐year experiment across urban allotments spanning an urbanisation gradient, we found no effect of added floral resources on nest uptake, while hymenopteran abundance ...

We compared the community structure of Aculeata bees and wasps in natural deciduous broadleaved forests and two coniferous plantations (Cryptomeria japonica, “Sugi” and Chamaecyparis obtusa, “Hinoki”) in southern Kyushu, Japan. Compared with natural forests, the dependence of Aculeata communities on the detritus‐based food chain increased in both ...

The research was carried out in 2005 − 2007 in the area of the Kórnik Arboretum and covered parasitoids of the Pimplinae, Poemeniinae and Diacritinae (Hymenoptera, Ichneumonidae) subfamilies, which control a number of plantdamaging phytophages.

Using extensive Malaise trapping, we collected a high richness of Pimplinae (86 species, 5892 individuals) in habitat types across a successional gradient. We found higher richness in forest than in nearby farmland, highlighting the importance of tropical forest in conserving parasitoid wasp richness.

Background: Lepidopteran caterpillars attack maize plants, and the main control methods involve the application of phytosanitary products, which is disadvantageous from an ecological point of view.
