Pollinators are responsible for the reproduction of many plant and crop species provide important diversity food webs cultural value. Despite critical ecosystem services provided by pollinators, rapid pollinator declines occurring in response to anthropogenic activities that cause loss suitable habitat. There is an opportunity urban green space support pollination locally across landscape. However, there a lack practical but evidence-based guidance on how can be designed effectively floral resources other habitat needs diverse assemblage pollinators. We examine existing research this paper address following questions specific insect pollinators temperate settings: (1) Which focus efforts increase cities?

At least 87% of angiosperm species require animal vectors for their reproduction, while more than two-thirds major global food crops depend on zoogamous pollination. Pollinator insects are a wide variety organisms that diverse biotic and abiotic resources. Many factors have contributed to serious decrease in the abundance populations diversity pollinator over years. This decline is alarming, European Union has taken several actions aimed at counteracting it by issuing new conservation policies standardizing member countries. In 2019, Green Deal was presented, aiming restore 100% Europe's degraded land 2050 through financial legislative instruments. Moreover, Common Agricultural Policies entailed greening measures habitats beneficial 10 The CAP (CAP 23–27) reinforces objectives strategic plans based eco-schemes defined national level countries, some states specifically conservation.

Shared use of a mass‐flowering crop drives dietary niche overlap between managed honeybees and bumblebees

Journal of Applied Ecology, Journal Year: 2024, Volume and Issue: 61(9), P. 2135 - 2145

Abstract Resource competition between wild pollinators and managed honeybees ( Apis mellifera ) has the potential to detrimentally impact insect biodiversity as well plant crop pollination. As are central place foragers, their competitive on bees is expected be structured by hive proximity, in conjunction with foraging decisions related landscape‐level resource availability. Yet, how these factors structure dietary niche overlap remains unclear. We conducted a field experiment seminatural grasslands, where honeybee densities buff‐tailed bumblebees Bombus terrestris were measured at four distances (<100, 500, 1000 2000 m) from experimentally placed apiaries, during after blooming period of mass‐flowering oilseed rape Brassica napus ). using standardized transect surveys, quantified species diet composition pollen samples collected both bee species. Honeybee highest near apiaries declined sharply beyond 500 m apiaries. However, was unrelated proximity but positively availability rape. Furthermore, there significant inter‐ intraspecific differences breadth throughout season.

Secondly, assessed theoretical for across zones Through systematic sampling, recorded following species: four hummingbirds, 20 21 bees, among which observed strong preference native plants such as Lantana camara Salvia leucantha. While some exotic also attracted pollinators, played central role supporting diverse pollinator populations. Areas greater floral diversity higher proportion species consistently exhibited better scores, underscoring critical link between flora activity. These findings highlight importance landscape management practices that strategically combine maximize resource availability, improving parks’ capacity sustain biodiversity.

Spatiotemporal variability and functional redundancy obscure effects of urbanization on strawberry pollinators

Ecosphere, Journal Year: 2025, Volume and Issue: 16(1)

Published: Jan. 1, 2025

Abstract Pollination services across rural–urban gradients may vary as land cover and other environmental attributes differentially influence pollinators. Most studies examining crop pollination, however, have been conducted in rural environments, while research urban areas has lagged behind despite growing interest agriculture. In this study, we hypothesized that increased urbanization would alter pollinator community composition due to a reduction natural within the surrounding landscape, potentially decreasing abundance. To evaluate hypothesis, three‐year study using strawberries focal crop. We characterized abundance, diversity, of bees 10 farms along gradient Michigan, USA. Across sites years, found urbanization, measured impervious surface cover, had no consistent effect on overall bee abundance diversity. However, influenced certain taxa, namely, Halictini which was positively associated with more environments year one Ceratinini negatively three. Sweat small carpenter were most frequent strawberry flower visitors although honey dominant at one. observed 61 species visiting flowers, commonly Lasioglossum, Ceratina , Augochlorella species. generalist foragers visited many each site.
