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.

Tree planting is a prevalent strategy to mitigate urban heat. cooling efficiency (TCE), defined as the temperature reduction for 1% tree cover increase, plays an important role in climate it regulates capacity of trees alter surface energy and water budget. However, spatial variation more importantly, temporal heterogeneity TCE global cities are not fully explored. Here, we used Landsat-based land (LST) compare TCEs at reference air level across 806 explore their potential drivers with boosted regression (BRT) machine learning model. From results, found that spatially regulated by only leaf area index (LAI) but variables anthropogenic factors especially city albedo, without specific variable dominating others. such difference attenuated decrease cover, most pronounced midlatitude cities. During period 2000-2015, than 90% analyzed showed increasing trend TCE, which likely explained combined result increase LAI, intensified solar radiation due decreased aerosol content, vapor pressure deficit (VPD) albedo. Concurrently, significant afforestation occurred many showing city-scale mean 5.3 ± 3.8% from 2000 2015. Over growing season, increases were estimated on average yield midday 1.5 1.3°C tree-covered areas. These results offering new insights into use adaptation warming planners may leverage them provide benefits if primarily planted this purpose.

Abstract ‘Urban Dry (Wet) Islands’ (UDI/UWI) represents microclimate change that impacts ecosystems and human well-being. However, causes of the UDI (UWI) phenomena are not fully understood due to lack empirical data. Here, we quantify using global observations atmospheric humidity, evapotranspiration (ET), land surface characteristics across 25 large urban agglomerations. We show (17) UWI (8) closely tied local ET, warming, Heat through intertwined linkages with water energy balances. is most pronounced in humid vegetated regions where mean urban-rural annual ET differences as high 215 mm, whereas found arid or climates dry summers. conclude can be used a single variable explain emerging environmental changes. Our study supports concerted strategy restoring nature’s power effective ‘Nature-based Solutions’ mitigate negative effects urbanization.

Abstract Heavy precipitation (HP) events can be preceded by moist heatwaves (HWs; i.e., hot and humid weather), both intensified urbanization. However, the effect of HWs on increasing urban HP remains unknown. Based statistical analyses daily weather observations ERA5 reanalysis data, we herein investigate urban-intensified dividing summer into NoHW- HW-preceded in Yangtze River delta (YRD) agglomeration China. During period 1961–2019, YRD has experienced more frequent, longer-lasting, stronger intense season (i.e., June–August), urbanization contributed to these increases (by 22.66%–37.50%). In contrast, effects are almost absent if remove from all events. Our results show that urbanization-induced associated with, magnified by, areas region. Moist conducive an unstable atmosphere stormy weather, they also enhance heat island intensity, driving over areas. Significance Statement The contribution heavy been widely reported previous studies. (hot extremes); however, it is unknown whether HP. We choose explore this question find contributes frequency, duration, maximum cumulative intensity season. signal not detectable other words, play a key role magnifying Given projected continue expanding occur with frequency future, water cycle merits further investigation.
