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 ...

Detection and Replication of Moku Virus in Honey Bees and Social Wasps
Transmission of honey bee viruses to other insects, and vice versa, has previously been reported and the true ecological importance of this phenomenon is still being realized.

The study demonstrates that sufficient B supply is crucial for successful rapeseed flower growth and fertility as well as for attracting pollinating insects, thus securing yield in a pollinator‐dependent crop. It is illustrated that climate change can pose a threat to crop yield via both direct effects, that is, an impaired nutrient uptake, and ...

Northern Distribution Records for Some Nearctic Pompilidae (Hymenoptera) [PDF]
Distributional records and nomenclatural changes are presented for 20 species of Nearctic Pompilidae. The records extend the species\u27 ranges northward in North America, are peripheral on the northern boundaries of the ranges, or fill in sizeable gaps ...

The present study analyzes wildlife species use indices and a vulnerability in the Aledjo Wildlife Reserve (AWR) in Togo. The Importance Value‐in‐use Index (IVIUsp) indicates that the most valued species are the patas monkey (Erythrocebus patas), the forest cobra (Naja melanoleuca), and the green mamba (Dendroaspis viridis).

Soil Traversing Arthropod Populations as Sampled by Pitfall Traps in Sunflower and Three Adjacent Habitats in Northeast Arkansas [PDF]
Soil traversing arthropod populations were sampled by pitfall traps in sunflower (Helianthus spp.) and three adjacent habitats during the months of July, August and September of 1980 and May, June, July and August of 1981.

ABSTRACT Biological invasions are major drivers of recent biodiversity changes, yet the genetic structure and ecological mechanisms underlying invasion dynamics remain poorly resolved in invasive social insects. In South Africa, the European wasp Vespula germanica (Hymenoptera: Vespidae), introduced in the 1970s, has spread remarkably more slowly than ...
