Abstract Urban expansion across the globe profoundly impacts local biodiversity. The growing body of urban ecology research on animals has largely focused mammals and birds, whereas knowledge insect conservation in areas remains limited. To anchor this Special Issue (SI), we have taken a broad approach to editorial conducted structured literature search set scene. We provide here an overview existing reviews conservation, indicate where articles included SI contribute developing our understanding point priority for further investigation. Key themes (at individual, species, and/or community level) include influence habitat quality, quantity land use type diversity; anthropogenic pollution (for instance, heat, noise, light chemicals); connectivity changes structure density genetic diversity. Insect diversity abundance broadly decline with loss habitat. Beyond this, variation responses different taxa, or regions, methodological limitations individual studies make it challenging identify general patterns. environments should focus applying ecological theory understand patterns; investigating interactions between climate change contexts; identifying novel biodiversity; addressing harmonising approaches; exploring social historical factors must also consider into how best communicate value insects humans.

Introduction Urban forests provide necessary habitat for many forest-associated bee species amidst development and fragmentation. These forest fragments a variety of important floral non-floral resources bees that encompass diversity functional guilds characterized by size, diet breadth, nesting, sociality, origin, seasonality. The relative importance edge vs. interior habitats to these organisms is not well understood. Methods Here, we compare communities between locations at eight in Athens, GA, USA. We also explore the effects stand structure, tree composition, ground cover type, presence snags downed wood on organisms. Results found abundance richness be higher than with distinct community compositions both locations. Canopy cover, invasive shrub influenced observed composition. determined most impactful traits influencing structure urban were nesting substrate, origin (native or exotic North America), breadth. Discussion Our findings will help establish local characteristics diversity, wild further our knowledge conservation value preserving communities.

Pervasive urbanization contributes to biodiversity declines globally, and with urbanization, road densities increase, amplifying habitat degradation landscape homogenization. However, as a major part of urban green space, roadside vegetation permeates the fabric and, if enhanced, can be used support insects, such wild bees. To analyze local landscape-scale effects enhanced roadsides on bee communities identify traits affected by filtering, we established 78 wildflower patches native seed mixture along five roads in Munich (S Germany). Species-poor regular management were control. During three-year experiment, sampled bees pan traps, monitored vegetation, analyzed diversity perimeter–area ratio space within radius 500 m. We gathered information morphological, behavioral, phenological, foraging calculated their abundance, species richness functional dispersion. Wild dispersion increased diversity. Functional was positively correlated distance from city center, indicating trait-based filtering. A fourth corner analysis revealed that small, short-lived, univoltine disadvantaged at roadsides. While discriminated areas high diversity, large prevailed outskirts, solitary associated edges. conclude contribute identifying groups help draw recommendations for effective conservation.

Abstract The nesting ecology of wild bumble bees is not well resolved, but information learned from discovered nests can be great conservation value. Data collected at on foraging patterns, caste‐specific behaviour and health (e.g., pathogens) are invaluable for understanding bee ecology, difficult to decipher solely observations away the nest. Post‐senescence nest excavation allows estimation colony size, caste numbers, documents pest incidence provides opportunities examine material stressors pesticides) use training purposes dogs). Wild often found opportunistically, there an absence standardised guidance data collection. We provide action plan ensure collection comparable across studies. This framework includes key questions methodological guidelines both in situ post‐season ordered by increasing complexity methods. To illustrate our framework, we example with recently Bombus affinis (rusty patched bee) nests. Through B. nests, novel patterns activity, changing activity levels over time, timing male gyne production, variable senescence, associations past rodent activity. Although individual discoveries may limited value forwarding strategies, aggregate collections many similar datasets critical importance species concern.

Abstract Understanding the impacts of urbanization and climate change on organisms has become increasingly critical in ecology conservation as these anthropogenic stressors negatively impact wildlife biodiversity, especially pollinators such bees. We analysed demographic (abundance sex ratio) morphological (body size wing wear) responses to inter‐annual variation four common wild bee species across an urban gradient Toronto, Canada. observed more significant shifts demography with precipitation than urbanization, diverse patterns depending species. The drier active season saw a decrease abundance for Agapostemon virescens Ceratina calcarata , whereas Bombus impatiens Xenoglossa pruinosa increased when compared previous year. Wetter seasons resulted smaller body sizes greater wear all examined. For larger bees ( A. B. X. ), increasing significantly females only foraging effort reduced intensity increased. small, cavity‐nesting bee, C. exhibited urbanization. Moderate better supported most assemblages morphology, suggesting that moderate land use provides green spaces adequate resources

Abstract Host plants required by specialist bee species may be limited in urban areas. We investigated the effects of urbanisation on Heriades truncorum , a solitary that is plant family Asteraceae. examined brood cell number, host and native pollen proportions (via DNA metabarcoding) nutritional composition provisions H. nests. Increasing resulted fewer cells higher genus diversity provisions. Bees collected from non‐native non‐Asteraceae genera, including new records for . overall was associated with decreased numbers. However, an increased Asteraceae genera number. The proportion were not changes Pollen provision related to or averaged P:L ratio ~1:1, similar These results suggest are equally beneficial Germany. Moreover, at more sites suggests level resources, particularly plants, could highly landscapes. While high conservation concern, our data demonstrate mechanisms which narrow less common specificity experience stress areas provides mitigation strategies.
