Abstract Urbanization exerts many pressures on species, yet little is known about how these impact species interactions. Studies of urban plant-pollinator systems provide mounting evidence that urbanization impairs pollinator movement in fragmented landscapes, the consequences for pollinator-mediated plant reproduction remains unclear. In non-urban areas, habitat corridors can facilitate organisms including pollinators, but whether interactions areas understudied. To examine environments and green influence interactions, we measured reproductive success native common milkweed ( Asclepias syriaca ), community structure its two years along urban-rural transects Greater Toronto Area, Canada, one which followed a corridor.

However, studies on the impact of tramways and surrounding infrastructure biodiversity is extremely rare despite potential ecological effects associated with this anthropogenic feature. Surprisingly, we found fewer 10 papers published tramway-wildlife interactions, which significantly (vs dozens thousands) that other transportation methods.

Although most of the wild bee species are ground-nesting, little is known about their nesting requirements and conservation measures to promote ground-nesting bees. Calcareous grasslands one species-rich habitats in Central Europe therefore essential for protecting diversity. The management practices calcareous so far often focused on plant populations, but order support declining insect additional have be considered nature conservation. As bees depend availability sites, we studied effects locally increased bare ground four large small Germany. Vegetation cover 24 experimental plots (1 m²) was removed. number nests as well presence these (here: activity) were compared control during six sampling runs. Results showed that fourteen times higher plots, positively related surrounding flower steeper slopes, independent grassland area.

In conclusion, our study emphasizes need consider resources vast majority bees, which ground-nesting.

Abstract Recent studies have emphasized forests as crucial habitat for wild bees. In Europe, most are managed following the principles of close‐to‐nature silviculture, which combine timber production and nature conservation.

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.
