Concentrated vulnerabilities in bees: Diet specialists have smaller geographic ranges

Insect Conservation and Diversity, EarlyView.
Niche breadth theory predicts a positive association between range size and diet breadth, which could concentrate risk among specialists, but this is not well established for bees. Using global occurrence data (range size) and natural history collection‐derived pollen data (diet breadth), we compared these traits in 633 species from six families and ...

Impact of the invasive ant Linepithema humile on native ant assemblages on the western slopes of Table Mountain and implications for ant-butterfly associations

, 2011
The Argentine Ant, Linepithema humile (Hymenoptera: Formicidae), is one of the world's most successful invasive species and invades undisturbed Fynbos habitats in South Africa, displacing native arthropod species and affecting interspecific associations.

The influence of cutting height on arthropods in farm grassland

Insect Conservation and Diversity, EarlyView.
Mowing at a cutting height of 13 cm slightly reduced the immediate negative impact of mowing compared to mowing at a height of 7 cm. Medium‐term effects overrode this benefit: the number of vegetation‐dwelling arthropods remained strongly reduced two and four weeks after mowing, regardless of the cutting height.

Canadian boreal restored mining sites sustain diverse pollinator communities, including species of conservation concern

Insect Conservation and Diversity, EarlyView.
Revegetated mine tailing storage facilities support pollinator abundance, diversity, richness and evenness comparable to recently logged boreal forest sites. Agronomic and spontaneous revegetation strategies host similar pollinator and Bombus community structures, indicating multiple rehabilitation approaches can effectively restore pollinator habitat.

Using trap-nests and Fabre-hives for study fauna and nesting biology of the solitary species of wasps and bees (Hymenoptera: Aculeata) in the Karadag Nature Reserve

, 2009
60 artificial nest constructions containing more than 2,200 nest cavities in the territory of the Karadag Nature Reserve and Lisya Bay during four seasons of investigations were exposed. More than 570 nests of aculeate Hymenoptera belonging to 26 species

Analysing the Ecological Requirements of the Australian Tortoise Beetle Trachymela sloanei (Blackburn, 1897) (Coleoptera: Chrysomelidae) to Determine the Prospects for Its Invasion Process

Journal of Applied Entomology, EarlyView.
ABSTRACT Invasive species pose a serious threat to biodiversity and result in significant economic costs. Although much effort is devoted to understanding invasive processes, some aspects are poorly understood, such as the early stages of invasions and the reasons for invasion failure.
