Changes in land cover by rapid urbanization have diminished the cooling effect of urban green spaces (UGS), exacerbating upward trend surface temperature (LST). A thorough and precise understanding spatio-temporal characteristics UGS LST is essential for mitigating localized high temperatures cities. This study identified changes configuration Shanghai from 2003 to 2022. The correlation between was explored using spatial autocorrelation analysis causal inference. results show that (1) high-temperature space had grown 721 km2 3059 2022; (2) suburbs, largest area tended decrease, while number patches increase, indicating a distinct feature suburbanization; (3) more significant correlation, sprawl primarily impacts large UGSs; (4) compared shape UGS, are key factor influencing regional LST. These findings enrich knowledge spatio−temporal relationship its urbanization, offering valuable insights building cooler

Changes in reptile and amphibian communities across urbanization gradients in eastern North America

Global Ecology and Conservation, Год журнала: 2023, Номер 48, С. e02734 - e02734

Urbanization is expected to alter animal communities, but few studies have generalized beyond patterns in individual cities. We used community-science data on reptiles and amphibians from 17 cities North America determine: 1) how species richness differs between surrounding areas, 2) whether the degree of landcover change vs. surroundings related magnitude richness, 3) urban communities are more similar each other or their 4) what characteristics reptile amphibian predict sensitive they urbanization. found that tended be somewhat lower (10-20%) as compared areas. For reptiles, decrease appeared primarily impervious surface cover, whereas for these changes tracked differences canopy cover. There was little evidence homogenization– city cluster with areas rather than species, those were less represented observations dependent cover specialized breeding habitats such streams vernal pools. Our results suggest capable supporting a relatively high amphibians. However, maintenance this may require attention habitat protection restoration, particularly common aquatic habitats.

Geographic variations in eco‐evolutionary factors governing urban birds: The case of university campuses in China

Journal of Animal Ecology, Год журнала: 2023, Номер 93(2), С. 208 - 220

Опубликована: Дек. 14, 2023

Abstract Urbanization alters natural habitats, restructures biotic communities and serves as a filter for selecting species from regional pools. However, empirical evidence of the specific traits that allow to persist in urban areas yields mixed results. More importantly, it remains unclear which are widespread utilizing spaces (urban utilizers) environment‐dependent traits. Using 745 bird 287 university/institute campuses 74 cities their pools across China, we tested whether occur correlated with regards biological (body mass, beak shape, flight capacity clutch size), ecological (diet diversity, niche width habitat breadth), behavioural (foraging innovation) evolutionary (diversification rate) attributes. We used Bayesian phylogenetic generalized linear models disentangle relative roles these predictors further, determine extent effects varied among different cities. found birds were more phylogenetically clustered than expected by chance, generally characterized larger breadth, faster diversification rate, innovation smaller body size. Notably, attributes explaining city temperature elevation, indicating filters environment dependent. conclude that, while typically small‐sized, generalists, innovative rapidly diversifying, key them thrive vary spatially, depending on climatic topographic conditions city. These findings emphasize importance studying within better understand contextual dependencies filtered environments.

The cooling performance of the energy-saving water spray window system under summer conditions in Nanning city southern China, is experimentally examined this study. By constructing two identical test rooms for comparison, experiment we analyzed effects temperature (22 °C, 26 30 °C), frequency (8, 10, 12, 15 min intervals), glass structure (single-layer, double-layer, triple-layer), air conditioning (26 27 28 29 and outer lamination thickness (30, 50, 100, 200 mm) on effect windows, aiming to determine optimal operating conditions. experimental outcomes demonstrate that appropriate mode involves using coldest source with a interval 8 min, three-layer cavity sprayed construction, an set at 100 mm, best °C). study found can reduce surface by 6 °C inner 2 °C. Moreover, more layers thicker lamination, higher energy saving rate; maximum rate 35.19%. has good adaptability significant Southeast Asia. scientifically selecting types fine-tuning modes, it expected efficient building conservation hot climates be achieved.
