Cities are expanding worldwide and urbanisation is considered a global threat to biodiversity. Urban ecology has provided important insights on how urban environmental changes might affect individuals, populations, species; however, we know little about the ecological impacts of alter species interactions. Species interactions backbone communities play crucial role in population community dynamics generation, maintenance structure Here, I review studies identify key mechanistic pathways through which processes could antagonistic mutualistic among species.

A global review of determinants of native bee assemblages in urbanised landscapes

Insect Conservation and Diversity, Journal Year: 2022, Volume and Issue: 15(4), P. 385 - 405

Abstract Loss of natural habitat through land‐use change threatens bees. Urbanisation is a major, increasing form, loss, and novel, pervasive form disturbance known to impact bee diversity abundance in variety often inconsistent ways. We conducted comprehensive, semi‐quantitative review, involving 215 studies, on responses bees urban landscapes, local landscape variables proposed influence diversity. Urban areas tend be favourable for compared with agricultural ones, but areas, host more abundant populations yet fewer species. Factors associated including changes foraging resources nesting substrate types availability, contribute abundance, species richness, composition native assemblages. However, the conclusions studies vary greatly because difference ecological traits bees, habitats surveyed, geographic region, as well noise data resulting from inconsistencies sampling methodology, definitions ‘urban’ ‘natural’.

The effects of urbanization on pollinators and pollination: A meta‐analysis

Ecology Letters, Journal Year: 2023, Volume and Issue: 26(9), P. 1629 - 1642

Published: June 22, 2023

Urbanization is increasing worldwide, with major impacts on biodiversity, species interactions and ecosystem functioning. Pollination an function vital for terrestrial ecosystems food security; however, the processes underlying patterns of pollinator diversity services they provide in cities have seldom been quantified. Here, we perform a comprehensive meta-analysis 133 studies examining effects urbanization pollinators pollination. Our results confirm widespread negative richness abundance, Lepidoptera being most affected group. Furthermore, responses were found to be trait-specific, below-ground nesting solitary Hymenoptera, spring flyers more severely by urbanization. Meanwhile, promote non-native pollinators, which may exacerbate conservation risks native species. Surprisingly, despite diversity, pollination service measured as seed set enhanced non-tropical likely due abundant generalists managed therein. We emphasize that local flowering plants could mitigate diversity. Overall, demonstrate varying magnitudes multiple moderators urban help guide actions biodiversity sustainable future.

Bumblebee resilience to climate change, through plastic and adaptive responses

Global Change Biology, Journal Year: 2021, Volume and Issue: 27(18), P. 4223 - 4237

Abstract Bumblebees are ubiquitous, cold‐adapted eusocial bees found worldwide from subarctic to tropical regions of the world. They key pollinators in most temperate and boreal ecosystems, both wild managed populations significant contributors agricultural pollination services. Despite their broad ecological niche at genus level, bumblebee species threatened by climate change, particularly rising average temperatures, intensifying seasonality increasing frequency extreme weather events. While some temperature extremes may be offset individual or colony level through regulation, bumblebees expected exhibit specific plastic responses, selection various traits, and/or range contractions under even mildest change. In this review, we provide an in‐depth up‐to‐date review on ways which overcome threats associated with current future global We use examples relevant fields physiology, morphology, behaviour, phenology, dispersal illustrate discuss contours new theoretical framework.

Urban fragmentation leads to lower floral diversity, with knock-on impacts on bee biodiversity

Abstract Bees and flowering plants are two closely interacting groups of organisms. Habitat loss fragmentation associated with urbanisation major threats to both partners. Yet how why bee floral richness diversity co-vary within the urban landscape remain unclear. Here, we sampled bees in green spaces investigate plant species richness, their phylogenetic pollination-relevant functional trait influence each other response fragmentation. As expected, abundance were positively related body size (but not diversity) increasing nectar-holder depth plants. Causal modelling indicated that bottom-up effects dictated patterns bee-flower relationships, diminishing thereby indirectly reducing abundance.

Can trait matching inform the design of pollinator‐friendly urban green spaces? A review and synthesis of the literature

Published: Jan. 1, 2024

Abstract Land use change is a major driver of pollinator decline and loss pollination services. For plant interactions to persist in rapidly changing urban systems, co‐occurring species must share matching traits, including phenological, morphological, physiological traits. Thus, the knowledge trait among interacting plants pollinators can aid design habitats enhance conservation value green spaces, but this remains relatively understudied. Here, we review how facilitates persistence creation new plant–pollinator networks. We highlight four drivers facilitating restructuring networks through gain areas. also show different pathways by which traits affected urbanization. Furthermore, functional help predict novel environments, those exotic species. Finally, application management practices, sustainable spaces that will accommodate functionally diverse within matrix.
