    Identification of the primary pollution sources and dominant influencing factors of soil heavy metals using a random forest model optimized by genetic algorithm coupled with geodet... by Tong Liu, Mingshi Wang, Mingya Wang, Qinqing Xiong, Luhao Jia, Wanqi Ma, Shaobo Sui, Wei Wu, Xiaoming Guo

    Published 2025-01-01
    “…Pollution sources were identified using Absolute Principal Component Score (APCS), with 8 anthropogenic factors, 9 natural factors, and 4 soil physicochemical properties mapped using Geographic Information System (GIS) kernel density estimation. Geodetector and a genetic algorithm optimized random forest model (GA-RF) were employed to quantify the dominant factors and precisely identify pollution sources. …”

    Status and annual change of vulnerability among middle-aged and elderly people with cardiometabolic multimorbidity in a division of Xinjiang Production and Construction Corps, 2017... by Ziqi WANG, Jieting CHEN, Mei ZHANG, Mingxia JING

    Published 2024-11-01
    “…The entropy weighting method was used to dynamically evaluate the vulnerability level of the CMM population from 2017 to 2021. Kernel density estimation was used to analyze the spatial and temporal evolution characteristics of the vulnerability level of the CMM population in different community types. …”

    Alteração da paisagem do município de Candeias do Jamari em Rondônia: uma análise temporal dos anos de 2007 a 2020. by Sheila Castro dos Santos, Siane Cristhina Pedroso Guimarães, Hélio Marques de Lira

    Published 2021-08-01
    “…The methodological basis is a qualitative and quantitative approach of the data and is anchored in satellite images and maps of hot spots produced from a set of data (2007, 2011, 1015, 2019 and 2020), where densities of the areas of study were calculated using the kernel density estimator, present in the Spatial Analyst extension of the free software QGIS 2.8.9 WIEN. …”

    A reliance on human habitats is key to the success of an introduced predatory reptile. by Tom Major, Lauren Jeffrey, Guillem Limia Russel, Rebecca Bracegirdle, Antonio Gandini, Rhys Morgan, Benjamin Michael Marshall, John F Mulley, Wolfgang Wüster

    Published 2025-01-01
    “…We investigated snake home range size using Autocorrelated Kernel Density Estimators (AKDE). Using AKDE-weighted Habitat Selection Functions we identified preferences for habitat features in a mosaic of habitats, and we used Integrated Step Selection Functions to further explore how these features influence movement. …”

    Effects of emigration on home range and behavior of Atlantic spotted dolphins (Stenella frontalis) by Brittini A. Hill, Denise L. Herzing, Jeremy M. Bono

    Published 2024-04-01
    “…We examined the home ranges for LBB residents on LBB (2005–2012), LBB immigrants on GBB (2013–2020), and GBB residents on GBB (2013–2020). Fixed kernel density estimators revealed LBB immigrant dolphins maintained significantly larger home ranges (34–43%) and core areas (42–94%) than both LBB and GBB residents. …”

    Tigers in their new territory: intraspecific interactions among the reintroduced tiger population in Panna Tiger Reserve, Central India by Supratim Dutta, Ramesh Krishnamurthy

    Published 2025-01-01
    “…To investigate spatial interactions, we used Autocorrelated Kernel Density Estimator methods. To capture dynamic interactions at different scales, we calculated Benhamou’s Movement Interaction index and a Correlation Coefficient (Cr) at two critical distance thresholds (Δ500m and 100m). …”
