No evidence for pronounced mate-finding Allee effects in the emerald ash borer (Agrilus planipennis Fairmaire) [PDF]

open access: yesNeoBiota
Allee effects are density-dependent barriers that can impact species establishment and population growth, such as through reduced mating success at low population densities.

Plant–pollinator networks in grassland working landscapes reveal seasonal shifts in network structure and composition

open access: yesEcosphere, Volume 10, Issue 1, January 2019., 2019
Abstract Declines in native bee populations can limit pollination services that support native plant communities and global food production. Mitigating the impacts on pollinators and ecosystems requires conservation actions that promote biodiversity and remain practical for producers.

Network rewiring and species turnover stabilize plant–pollinator interactions across habitats and seasons in dry forest

open access: yesEcosphere, Volume 17, Issue 5, May 2026.
Abstract Mutualistic interactions between plants and pollinators are fundamental to biodiversity maintenance and ecosystem resilience, yet their dynamics across space and time in tropical dry forests have not been widely examined. We analyzed plant–pollinator networks across seasons and habitat types in the highly seasonal and fragmented dry forest of ...

Taxonomic revision and conservation concerns of the trapezitine genus Croitana Waterhouse, 1932 (Lepidoptera: Hesperiidae) from Australia

open access: yesAustral Entomology, Volume 65, Issue 2, May 2026.
Abstract Croitana Waterhouse, 1932 (Trapezitinae) is a small genus of skippers endemic to Australia, with most species restricted to semi‐arid and arid biomes where the larvae specialise on grasses (Poaceae) in the genera Neurachne R.Br., Enteropogon Nees and Austrostipa S.W.L. Jacobs & J.Everett.

A cuckoo in wolves' clothing? Chemical mimicry in a specialized cuckoo wasp of the European beewolf (Hymenoptera, Chrysididae and Crabronidae)

open access: yesFrontiers in Zoology, 2008
Background Host-parasite interactions are among the most important biotic relationships. Host species should evolve mechanisms to detect their enemies and employ appropriate counterstrategies.

The potential of weeds in arable fields to support pollinator assemblages

open access: yesWeed Research, Volume 65, Issue 1, January/February 2025.
Abstract To what extent are weeds on arable land useful to pollinators in an arable‐dominated landscape? We sampled the weed flora in fields under conventional or organic farming in SE Sweden. More specifically, we noted the frequency of flowering among weeds that scored high on a pollinator index, henceforth ‘pollinator‐friendly weeds’.

Home sweet home: Evaluation of native versus exotic plants as resources for insects in urban green spaces

open access: yesEcological Solutions and Evidence, Volume 5, Issue 3, July–September 2024.
Our study shows that planting urban green spaces with native plants as a food source for flower‐visiting and leaf‐feeding insects can be a way to promote different insect species in urban areas. Planting or seeding based only on the needs of honey bees is less suitable for the conservation and promotion of insect diversity in urban green spaces, as the
