Managing urban areas for insect pollinators: As town and cities continue to grow how can land managers help insect pollinators in urban areas? [PDF]

open access: yes, 2015
Insect pollinators are essential for food production and wild flower reproduction yet these important insects are declining in the UK and in other regions of the world.

Observations on the Nesting Behavior of \u3ci\u3eAuplopus Caerulescens Subcorticalis\u3c/i\u3e and Other Auplopodini (Hymenoptera: Pompilidae) [PDF]

open access: yes, 2017
Nest searching and mud and prey transport behavior in a small aggregation of Auplopus caerulescens subcorticalis nesting in a concrete cellar foundation in upstate New York are delineated. The contents of nine cells of this subspecies are identified, the

Bionomy and Nesting Behavior of the Bee Epanthidium tigrinum (Schrottky, 1905) (Hymenoptera: Megachilidae) in Trap-Nests

open access: yesSociobiology, 2020
About 85% of pollinating bees are solitary, but few are used for agricultural pollination. The Anthidiini tribe looks very promising in Brazil, in the light of ecosystem utility, but  it is still a species with poorly scientific research[EdM1] .

Notes on \u3ci\u3eDianthidium Simile\u3c/i\u3e (Cresson) (Hymenoptera: Megachilidae) in Michigan [PDF]

open access: yes, 2018
Dianthidium simile (Cresson) is a small ground-nesting megachilid bee restricted to sandy areas in Michigan, often bordering lakeshores. Females dig their nests in sand, at the base of dried clumps of grass. Nests are small clusters of cells, formed from

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys

open access: yesAdvanced Engineering Materials, EarlyView.
This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Unveiling the trap-nesting bees and wasps’ fauna (Hymenoptera: Apocrita) and associated organisms of the Jardim Botânico do Rio de Janeiro, Brazil [PDF]

open access: yesPapéis Avulsos de Zoologia
Urban areas, as cities, are frequently overlooked as refuges for the native fauna. However, these places may support several species and house relevant biodiversity contributing to important ecosystemic functions.

Broadband, Flexible, Skin‐Compatible Carbon Dots/Graphene Photodetectors for Wearable Applications

open access: yesAdvanced Functional Materials, EarlyView.
Broadband, flexible photodetectors integrating nitrogen‐rich carbon dots with single‐layer graphene on plastic substrates are demonstrated. A biocompatible chitosan–glycerol electrolyte enables efficient low‐voltage gating and on‐skin operation. The devices exhibit ultraviolet‐to‐near‐infrared response, mechanical robustness under bending, and verified

What do we know about Neotropical trap-nesting bees? Synopsis about their nest biology and taxonomy

open access: yesPapéis Avulsos de Zoologia
Cavity-nesting bees are enigmatic because they are difficult to observe in the wild, hence trap-nests (man-made cavities) provide the means by which these bees may be studied.

Does Seasonality Affect the Nest Productivity, Body Size, and Food Niche of Tetrapedia curvitarsis Friese (Apidae, Tetrapediini)?

open access: yesSociobiology, 2018
Tetrapedia curvitarsis Friese is a widely distributed species, frequently attracted by trap-nests. Previous studies have revealed a higher frequency of nesting in the wet season and dimorphism between the sexes, with females exhibiting larger body size ...
