Assessment of the nursery environment and distribution of Ayu, Plecoglossus altivelis (Actinopterygii, Osmeriformes, Plecoglossidae), in Vietnam

Acta Ichthyologica Et Piscatoria, Journal Year: 2025, Volume and Issue: 55, P. 19 - 29

Published: March 19, 2025

The distribution of larvae and juveniles Ayu, Plecoglossus altivelis (Temminck et Schlegel, 1846), is shaped by intricate interplays involving environmental variables anthropogenic influences. interplay equilibrium among these factors will govern the abundance Ayu fish in estuarine settings. In this investigation, a hybrid Ant Colony Optimization-Adaptive Neuro-Fuzzy Inference System (ACO-ANFIS) model was utilized to enhance precision juvenile’s occurrence estimation for period from 2021 2022. outcomes evinced that displays strong predictive capabilities, with R 2 test > 0.75, AUC 0.79. Among parameters, temperature, salinity, turbidity exhibit highest correlations occurrence, values 0.47, 0.54, 0.40 Ka Long estuary, 0.49, 0.50, 0.42 Ba Lat respectively. presence species limited northern Vietnam, albeit declining pattern estuary estuary. study’s propose identification suitable habitats cartography are invaluable scrutinizing ramifications natural influences on distribution.

Application of Remote Sensing and Machine Learning Technologies to Assess the Impact of Urban Expansion on Forest Degradation and PM2.5 and PM10 Emissions in Hanoi for Urban Health Protection

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Urban expansion is an unavoidable phenomenon in the realm of economic and social progress; nonetheless, it brings forth significant environmental repercussions, notably diminishment green spaces escalation fine particulate matter concentrations atmosphere. The findings this research indicate that proportion developed land has surged from 13.92% 1995 to 32.27% 2025, while forest coverage markedly declined, particularly between 2015 witnessing a loss 6,297.55 ha. This shift not only constricts areas but also exacerbates levels matter, especially regions characterized by high urban density substantial industrial operations. Ant Colony Optimization-Generative Adversarial Network (ACO-GAN) model exhibited exceptional efficacy, achieving RMSE values 7.38 9.76 for PM2.5 PM10, respectively, alongside R² coefficient surpassing 0.82. Variables such as construction (CONST DEN), surface temperature (LST), Normalized Difference Vegetation Index (NDVI), Soil-Adjusted (SAVI) have been recognized most pivotal determinants affecting concentrations. Additionally, reveal with elevated density, locales like Noi Bai Dong Anh, demonstrate alarmingly whereas abundant vegetation, Ba Vi Mountain, exhibit considerably lower highlights essential function alleviating air pollution safeguarding living environment. These insights elucidate adverse effects urbanization on quality establish scientific foundation advocating sustainable management planning strategies.
