Published: Feb. 21, 2024

Background Urban gardens, despite their transformed nature, serve as invaluable microcosms for a quantitative examination of floral resource provision to urban pollinators, considering the plant’s origin. Thus, knowledge has increased, emphasizing importance these green areas hosting and conserving pollinator communities. However, there is significant gap concerning changing availability native exotic resources over time impact on structuring interaction networks with specific pollinators. Methods Over year-long period, monthly surveys were conducted record both plant species visited by hummingbirds in an garden at Tlaxcala, Mexico. Flower visits recorded, total flowers each tallied. Additionally, all observed recorded during transect walks, regardless visits, determine hummingbird abundance. The interactions summarized using matrices, network descriptors like connectance, specializacion, nestedness, modularity computed. Plant core periphery also identified. Lastly, simulations performed assess network’s resilience extinction highly connected species, including those previously situated core. Results We 4,674 between 28 eight species. majority plants showed ornithophilic syndrome, 20 considered exotic. Despite asynchronous flowering, was overlap across different throughout year. Exotic Jacaranda mimosifolia Nicotiana glauca produced more annually than abundance varied study, Saucerottia berillyna being most abundant plant-hummingbird displayed high indicating generalization interaction. Significant nestedness observed, mainly influenced enriched plants, while Basilinna leucotis Cynanthus latirostris played central roles among hummingbirds. Network remained generally high. Conclusions Our findings provide valuable insights into dynamics structure influence perturbations. Understanding managing such crucial conservation sustainable functioning ecosystems.

Urban greenspaces are recognized as a benefit to pollinator conservation. Selective planting of attractive flowering plants can improve the conservation value urban greenspaces. However, functional traits that moderate preference merits further study. We analyzed 98 ornamental and spontaneous plant species for ten categories floral across twelve parks or campus in Wuhan, megacity located central China. Our results revealed that: (1) Plant vary enormously their visitation rate. (2) For Lepidoptera, number individuals plot was lower disk/bowl-shaped flowers than other flower shapes, it negatively corelated with corolla tube length. The Diptera higher white, red/pink yellow/orange blue/violet flowers. (3) Honeybees preferred exotic annual/biennial herbaceous species, disk/bowl flag Solitary bees horizontal, lip most frequently visited upward-facing, heads Lepidoptera funnel-shaped heads. Blue/violet diverse orientation were by groups. recommend native woody (Nandina domestica, Thymus quinquecostatus, Lagerstroemia indica, Tamarix austromongolica) (Centaurea cyanus, Borago officinalis, Portulaca grandiflora, Echinacea purpurea) support multiple As preferences differ among pollinators, increasing richness is conducive promote overall diversity.

Drought response and urban-pollinator attractiveness of ornamental plant species

Basic and Applied Ecology, Journal Year: 2024, Volume and Issue: 78, P. 1 - 13

Published: April 21, 2024

Faced with pollinator declines, cities could serve as refuges for biodiversity conservation by managing floral resources in public green spaces. Ornamental plants play an important role attracting pollinators because they form part of urban management. However, knowledge how their traits respond to drought is lacking, and it unknown whether will be suitable under future climates. The main objective this study was determine the covariation ornamental plant species effects on them. To end, a city greenhouse we measured eight commonly used spaces France. We subjected control treatment or treatment, reducing volume frequency watering. observed interspecific variability among these change between pollen quantity nectar treatment. Drought influenced morphological related display more than other traits, mean decreases 28% height, 35% area 58% number units. seemed attractive different morphotypes depending unit number, sugar concentration tube depth, most visits made Hymenoptera. These results are expected encourage green-space managers select according functional characteristics adapt choice climate change.

Pollinators respond positively to urban green space enhancements using wild and ornamental flowers

Insect Conservation and Diversity, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 10, 2024

Abstract Pollinator diversity and abundance are under direct threat from human activities. Despite societal dependence on pollinators for crop production, humankind continues to drive pollinator declines through agricultural intensification urbanisation. Urban environments can provide refuge some pollinators. There is a need, however, understand how communities be supported in these areas while also considering needs. Public green spaces promising avenue target plant–pollinator conservation measures an urban setting due their large area, high low biodiversity. We used paired design compare the plant community, community interactions of (i) public enhanced with wildflower meadows pollinator‐friendly ornamental plantings (ii) control unenhanced spaces. The planting types within sites were separately compared. Our results show that not only was overall higher than sites, but complexity wild Hymenoptera Diptera groups. negative impact urbanisation groups reduced compared sites. Planting both plants significantly increased visits alone. suggest enhancing has positive effects key help mitigate impacts Non‐native play role maintaining recreational functions. This supports mixed‐planting approach improving people nature.
