Fragmented grasslands in different landscape structures provide different opportunities for cavity‐nesting Hymenoptera

Insect Conservation and Diversity, EarlyView.
Grassland fragmentation effects on cavity‐nesting Hymenoptera are habitat‐specific. Isolated sand steppe fragments are associated with higher brood‐cell abundance. In loess steppes, higher flower frequency increases bee brood‐cell production and parasitoid activity. Abstract The global decline in insects threatens ecosystem functioning, but the drivers

Local habitat, not landscape diversity, drives richness and reproduction of cavity‐nesting bees and wasps in agricultural landscapes

Insect Conservation and Diversity, EarlyView.
Local habitat type and hedgerow cover strongly shape bee and wasp richness, but only weakly their reproductive output, outweighing the landscape diversity effects at the 1‐km2 scale. Forests host more wasp but fewer bee species, whereas orchards support high richness of both; bee reproduction patterns are driven by one dominant species, while wasp ...

Youngstown Sheet and Tube Company's Campbell Works ore bridge

, 1920
The ore bridge at the Youngstown Sheet and Tube Company's Campbell Works in East Youngstown (Campbell), Ohio, spanned the stockyard, well above the tall piles of ore. A large crane recovered ore from the piles in the stockyard and moved it to bins.

Food resources are more important than nesting resources for explaining wild bee diversity in urban gardens Nahrungsressourcen haben einen größeren Einfluss auf die Wildbienendiversität in urbanen Gärten als das Nistangebot

Insect Conservation and Diversity, EarlyView.
Urban community gardens showed a high wild bee diversity with 168 recorded species, representing roughly 30% of Germany's wild bees, including threatened species like Osmia mitis and Coelioxys lanceolata. Floral resources, not nesting resources or habitat availability, were the main drivers for wild bee taxonomic and functional diversity.

Youngstown Sheet and Tube Company's Campbell Works blast furnace cleaning

, 1910
A view of the blast furnace at the Youngstown Sheet and Tube Company's Campbell Works, East Youngstown (Campbell), Ohio, ca. 1910-1919. Blast furnace gas contains a large amount of residual dust--between 100 and 200 tons per day for a single 1300-ton ...

Conifer host identity shapes wood‐boring beetle communities more than climate across a latitudinal forest gradient in Quebec (Canada)

Insect Conservation and Diversity, EarlyView.
Host tree identity and latitude shaped wood‐boring beetle assemblages, with species richness declining northward but community composition varying among regions and hosts. Host tree species influenced beetle communities more strongly than climate; black spruce supported the most species, while eastern hemlock hosted very few.
