Floral richness drives flower–insect networks in city gardens and allotments

Ecological Entomology, EarlyView.
Floral richness was the main driver of flower visits within green spaces whilst green space in the surrounding landscape influenced flower visits by amplifying the effects of floral richness. Native plants received more visits than non‐native plants, although flower visitor richness to non‐native plants increased later in the season as non‐native plant

Not all crickets are equal: selective shrike predation highlights the conservation value of diverse arthropod communities to grassland birds

Ibis, EarlyView.
Understanding dietary preferences and prey selection is pivotal for interpreting the ecology and conservation needs of threatened species. We investigated the diet composition and prey selection of the Red‐backed Shrike Lanius collurio in a montane grassland of the central Italian Apennines, with special regard to sex‐related differences and the ...
