Geographic Variation in the Diet of Red Knot (Calidris canutus) Chicks Reflects Local Prey Communities

open access: yesJournal of Biogeography, Volume 53, Issue 3, March 2026.
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

open access: yesEcological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
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 ...

Conversion From Natural Broad‐Leaved Forest to Conifer Plantation Increases Relative Detritus Dependency of Aculeata Communities

open access: yesEcological Research, Volume 41, Issue 1, January 2026.
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 ...

Parasitic wasps of the Pimplinae, Poemeniinae and Diacritinae (Hymenoptera, Ichneumonidae) subfamilies at Kórnik Arboretum

open access: yesFolia Horticulturae, 2009
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.

Local species richness of parasitoid wasps (Ichneumonidae: Pimplinae) in Afrotropical forest: Conservation perspectives

open access: yesInsect Conservation and Diversity, Volume 19, Issue 1, Page 198-210, January 2026.
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.

Faunistic composition and seasonal occurrence of parasitoid and predatory wasps in maize intercropped with beans

open access: yesJournal of Ecology and Environment
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.

Ecosystem services provided by spiders

open access: yesBiological Reviews, Volume 100, Issue 6, Page 2217-2236, December 2025.
ABSTRACT Spiders, ubiquitous and abundant predators in terrestrial ecosystems, often are the subjects of an unjust negative perception. However, these remarkable creatures stand as unsung heroes within our ecosystems, contributing a multitude of ecosystem services critical to human well‐being.

Parasitoid inventarisation of European corn borer (Ostrinia nubilalis Hübner, 1796) and options for its biological control in Slovenia

open access: yesActa Agriculturae Slovenica, 2016
European corn borer (Ostrinia nubilalis) (ECB) is an important maize pest in central and northern Europe. Presently it is controlled by insecticides or biological agents such as Trichogramma brassicae in several European countries, excluding Slovenia ...
