Assessment of vulnerability to fluvial floods: Case of municipalities of the Gidra River Basin, Slovakia
Published 2024-08-01“…Material and methods: Three indicators (number of buildings within a 100 m radius from the watercourse; length of roads within a 100 m radius from the watercourse; and number of bridges over a watercourse) representing the economic vulnerability, and seven indicators of social vulnerability (population density of municipalities; share of residents aged 65+ in the total number of residents; share of unemployed residents in the total number of economically active residents; share of households with six and more persons in the total number of households; share of incomplete households in the total number of households; share of residents without education and with primary education in the the total number of residents; and share of residents with disabilities in the total number of residents) were used to determine the respective economic flood vulnerability sub-index (EFVsI) and social flood vulnerability sub-index (SFVsI). …”

Environmental sustainability of urban expansion: Implications for transport emissions, air pollution, and city growth
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
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
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.…”
