    Environmental sustainability of urban expansion: Implications for transport emissions, air pollution, and city growth by Susana Lopez-Aparicio, Henrik Grythe, Arkadiusz Drabicki, Konrad Chwastek, Kamila Toboła, Lidia Górska-Niemas, Urszula Kierpiec, Miha Markelj, Joanna Strużewska, Bartosz Kud, Gabriela Sousa Santos

    Published 2025-02-01
    “…Results indicate that a compact future scenario reduces transport CO2 emissions and urban NO2 levels, though increases in population density raise exposure to air pollution. A sprawl future scenario increases CO2 and NOx emissions due to longer commutes and congestion, and NO2 levels increase up to 25% in parts of the city. …”

    Characteristics, location, and usage patterns of resting burrows in Chinese pangolins: Insights from radio-telemetry tracking by Nick Ching-Min Sun, Jing-Shiun Lin, Kurtis Jai‑Chyi Pei

    Published 2025-01-01
    “…To conclude the findings:1) burrow count, while useful for identifying pangolin presence, is not a suitable quantitative indicator of population density. 2) Most resting burrows had compacted soil at the entrance, which could be mistaken for old or inactive burrows in other studies. 3) Resting burrows function as permanent structures that are reused across seasons instead of seasonal adaptations. 4) Preserving low-disturbance habitats will be critical for ensuring sufficient resting burrow sites, thereby supporting the long-term viability of pangolin populations. …”

    Assessment of ecological environment quality and their drivers in urban agglomeration based on a novel remote sensing ecological index by Fangyuan Lu, Chen Zhang, Haoyu Cao, Xibin Wang, Tong Zheng, Zhenfang Huang

    Published 2025-01-01
    “…However, notable regional disparities exist, with a spatial pattern characterized by “low EEQ in the northwest and high in the southeast.” (2) An analysis of NRSEI variations over this period indicates that the YRDUA’s EEQ has remained largely stable, although ecological degradation is concentrated in densely populated, low-lying areas near lakes, rivers, and plains. (3) Topographic complexity, economic development, and population density are the primary factors driving spatial differences in EEQ, with interactive effects among these factors exerting a more significant influence than individual factors alone.…”
