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

Ecology Letters, Год журнала: 2023, Номер 26(9), С. 1629 - 1642

Опубликована: Июнь 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.

Bees in the city: Findings from a scoping review and recommendations for urban planning

AMBIO, Год журнала: 2024, Номер unknown

Опубликована: Май 20, 2024

Over the last decades, bee biodiversity has dropped sharply due to land use change, including urbanization. To contrast this, recent research pointed cities as a hotspot for bees. Because of this ambiguity, scoping review been conducted examine urban characteristics that impact bees and how are impacted. A total 276 articles were analyzed against landscape local habitat characteristics. The key findings include first natural areas more valuable since levels higher. Second, generally score better than agricultural rural areas. Third, plant positively influences biodiversity. Fourth, environment strongly affects some traits proportion native For making friendly inclusive, we recommend maintain areas, connect ecosystems, encourage floral abundance diversity increasing size green overall.

The effect of urbanisation and seasonality on wild bee abundance, body size and foraging efforts

Ecological Entomology, Год журнала: 2023, Номер 48(4), С. 499 - 507

Опубликована: Апрель 15, 2023

Abstract Anthropogenic changes highly impact the world's biodiversity. An important human‐driven change to natural environments is increasing urbanisation, which responsible for decreasing suitable habitats many wild species, including bees. In this study, we investigate if three levels of urbanisation (low, medium and high) affect body size, foraging efforts abundance sweat bee Agapostemon virescens . Overall, A. was more abundant in medium‐urbanised sites. Second‐generation females (summer bees) were than overwintered (spring at all urbanisation. According female bees larger urbanised sites male efforts, observed an increase wing wear during spring a decrease summer. It also found female‐biased sex ratio under high male‐biased low Our results suggest that can still provide sufficient nesting resources addition our findings higher sites, maintaining different heterogenous landscapes within populous city might have positive on be sustainability.

Urban wild bee well‐being revealed by gut metagenome data: A mason bee model

Abstract Wild bees are ecologically vital but increasingly threatened by anthropogenic activities, leading to uncertain survival and health outcomes in urban environments. The gut microbiome contains features indicating host reflecting long‐term evolutionary adaptation acute reactions real‐time stressors. Moving beyond bacteria, we propose a comprehensive analysis integrating diet, bacteriome, virome, resistome, their association understand the status of lives better. We conducted study on mason ( Osmia excavata ) across 10 agricultural sites Suzhou, China, using shotgun metagenome sequencing for data derived from total DNA. Our findings revealed that most ingested pollen originated Brassica crops unexpected garden tree Plantanus , floral resources at supported with limited plant diversity. Varied city landscapes site‐specific flowers all contributed sustenance. bacterial community, dominated Gammaproteobacteria, showed remarkable structural stability 8 suggested perturbations 2 sites. Antibiotic resistance gene profiles highly varied prevalent unclassified drug classes, highlighting environmental threats both humans. virome identified honeybee pathogens, suggesting potential virus spillover. Many unknown bacteriophages were detected, some which targeted core underscoring role maintaining homeostasis. These multifaceted metagenomic insights hold predict bee identify threats, thereby guiding probiotic development management effective conservation.

Warming up through buildings and roads: what we know and should know about the urban heat island effect on bees

Urbanization leads to cities having higher temperatures than surrounding non-urban areas [this is known as the urban heat island (UHI) effect]. Very little about impacts of UHI effect on bees, despite importance temperature many aspects bees’ life suggesting that these may be not negligible. In this study, we aimed highlight how could impact relevant functional traits bees in cities, proposing several ad hoc hypotheses for have thus far been investigated only few studies or at all, based what know from studies. The was shown influence bee body size, and generally tended reduce size cities. Urban also affect wing morphology, their overall flight morphology parameters.

Urban Pollination Ecology

Pollination is an essential component of plant reproduction that transformed by the novel environmental conditions in cities. We summarize patterns urban and trace mechanisms which environments influence pollination, beginning at level individual plant. then progress through several processes unique to animal-pollinated plants, including plant–pollinator signaling, community-level effects, emergent interaction networks. Last, we review pollen movement spatial mating Despite a global signal reduced pollination urban, effects vary among studies, extent dispersal city remains difficult predict. highlight recent progress, as well areas where new research will help crystallize our understanding pollination. These advances have potential spur exciting insights into network dynamics movement, may ultimately inform sustainable design conservation ecosystem services.

Numerous studies have explored the organization of pollination networks and factors influencing these interactions at various spatial temporal scales. Within networks, species vary in their significance influence on one another (i.e. interactive roles), understanding which determine this enables us to better comprehend interconnected relationships that drive resilience diversity ecosystems. Nevertheless, despite ectothermic nature bees potential impact social behaviour bee foraging patterns plants, amount theoretical empirical information available regarding how thermal tolerance limits sociality affect roles within remains relatively scarce. In study, we assess physiological (thermal tolerance) traits shape role a network coastal environment Gulf Mexico, Mexico. For sociality, classified as eusocial, subsocial, solitary while for tolerance, used both warmest critical maximum, CT max ) coldest minimum, m temperature. general, found bees' explain studied.
