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.

The degree of urbanisation reduces wild bee and butterfly diversity and alters the patterns of flower-visitation in urban dry grasslands

Scientific Reports, Год журнала: 2023, Номер 13(1)

Abstract Insect-provided pollination services are increasingly threatened due to alarming declines in insect pollinator populations. One of the main threats pollinators and consequently is urbanisation. Here, we investigate effects local habitat quality (patch size, flowering plant richness, bare soil cover, vegetation structure), degree urbanisation (impervious surfaces) 3D connectivity on bee, hoverfly butterfly flower visitors plant-flower visitor networks flower-rich urban dry grasslands. Overall, influenced communities. Although abundance increased with urbanisation, bee species richness decreased increasing impervious surfaces. Flowering ground nesting resource availability were positively related structure boosted visitation rates. In terms plant–pollinator interactions, visited a lower proportion available plants more urbanised areas network modularity specialisation patch size. Our findings show that grasslands valuable habitats for species-rich communities further highlight importance minimizing intensity potential management practices support biodiversity cities.

Plant distribution, ecological traits and diversity patterns of vegetation in subtropical managed forests as guidelines for forest management policy

Frontiers in Forests and Global Change, Год журнала: 2024, Номер 7

Forest vegetation is an important component of forest ecosystems, contributing to terrestrial plant diversity while also providing a variety ecological services. In managed landscapes, plantations emerge as dominant kinds after stand-replacing disturbances. However, the dynamics cover, diversity, and composition in plantation forests remains poorly understood subtropical region. Our study recorded rich floral with 173 angiosperm species, characterized by varying life forms distinct flowering phenology. The uneven distribution species across families demonstrated complexity ecosystem, Poaceae being dominant. Diversity patterns among different types varied, Dalbergia sissoo Populus nigra exhibiting higher richness diversity. Conversely, Eucalyptus camaldulensis Morus alba displayed lower emphasizing influence type on biodiversity. Non-metric multidimensional scaling (nMDS) PERMANOVA analyses revealed significant dissimilarity composition. Indicator analysis identified unique compositions within each type, importance conserving specific protect indicator maintained distinctiveness. Canonical Correspondence Analysis (CCA) that road accessibility, stem cutting, fire significantly influenced patterns. present research underscored considering management for biodiversity conservation highlighted environmental variables’ formation communities. These results provided major implications sustainable efforts tropical regions.

Exploring Ionic Liquid-based Liquid-Liquid Extraction as Benign Alternative for Sustainable Wastewater Treatment

Sustainability & Circularity NOW, Год журнала: 2025, Номер unknown

Опубликована: Янв. 13, 2025

The uncontrolled release of industrial effluents containing micropollutants (MPs), dyes, and heavy metal ions contaminates natural water bodies posing threats to health the environment. Conventional treatment methods often struggle with challenges such as prolonged processing time, low specificity, risk producing secondary pollutants. Liquid-liquid extraction (LLE) technique utilizing ionic liquids (ILs) has emerged a viable alternative for elimination contaminants from wastewater. ILs, characterized by minimal volatility tunable physicochemical properties, facilitate precise effluent. IL-LLE streamlines experimental setup, lowers energy consumption, promotes recyclability reuse, enhances mechanistic understanding, hence provides sustainable effluent treatment. This review comprehensive analysis approaches wastewater treatment, commencing an overview historical evolution tracing their progression initial research contemporary advanced applications. article primarily examines practical applications IL-LLE, demonstrating how these are employed efficiently remove diverse both simulated actual samples. As whole, consolidates versatility efficiency IL-based LLE in addressing various

Identifying urban rewilding opportunity spaces in a metropolis: Chongqing as an example

Ecological Indicators, Год журнала: 2024, Номер 160, С. 111778 - 111778

The worldwide urbanization has resulted in a massive loss of natural habitats, which is threatening biodiversity and socio-ecological sustainability. Urban rewilding strategy aiming to restore the complexity, autonomy self-sustainability urban ecosystems by interlinking ecological processes while minimizing or gradually reducing human disturbances. benefits are widely acknowledged; however, there remains knowledge gap concerning identification suitable locations for methodologies assessing potential areas. In this study, we proposed an approach that can be used accurately identify opportunity spaces (UROS, existing wildness areas offering conditions conducive establishment new wildness), integrating data on spatial heterogeneity, disturbance. UROS Chongqing, China was evaluated mapped at city-wide scale, with subsequent validation results through assessment species richness spontaneous herbaceous communities, serve as pioneer processes. revealed positive correlation between high-scoring increased herbs, thus confirming feasibility method. Eleven primary types were identified, majority displaying scattered linear distributions. Most very characterized expansive woodland expanses situated outskirts high-density built-up substantial water bodies within Notably, nearly half encompass 900 m2 less, underscoring importance initiatives targeting not only preservation extensive robust connectivity but also revitalization fragmented limited central regions. methodology applicable offer insights guidance execution conservation efforts, contributing sustainable regional development context rapid urbanization.

Substantial urbanization‐driven declines of larval and adult moths in a subtropical environment

Global Change Biology, Год журнала: 2024, Номер 30(3)

Опубликована: Март 1, 2024

Abstract Recent work has shown the decline of insect abundance, diversity and biomass, with potential implications for ecosystem services. These declines are especially pronounced in regions high human activity, urbanization is emerging as a significant contributing factor. However, scale these traits that determine variation species‐specific responses remain less well understood, subtropical tropical regions, where urban footprints rapidly expanding. Here, we surveyed moths across an entire year protected forested sites gradient to test how caterpillar adult life stages (Lepidoptera) impacted by urbanization. Specifically, assess development affects total biomass caterpillars, abundance quantify richness phylogenetic macro‐moths development. Additionally, explore life‐history condition species' At community level, find decreases moth abundance. We also sharp response phylogeny, leading decrease species more sites. Finally, our study found smaller than larger environments, perhaps highlighting tradeoffs metabolic costs heat favoring over relative benefits dispersal moths. In summary, research underscores far‐reaching consequences on provides compelling evidence forests alone may not be sufficient safeguard biodiversity cities.
