EcoNicheS is a novel, user-friendly tool designed to facilitate ecological niche modeling and species distribution modeling, niche overlap and connectivity analysis and support biodiversity conservation efforts. This R package offers a streamlined workflow for researchers and conservation practitioners to assess habitat suitability and predict species distributions in response to environmental changes. Leveraging the power of R programming and the Shinydashboard, EcoNicheS provides an intuitive interface for data input, model parameterization, and visualization of results. By integrating species occurrence data with environmental variables, users can generate robust predictions of species distributions, aiding in the identification of priority areas for conservation and management actions. EcoNicheS incorporates advanced modeling techniques to account for uncertainty and variability in species-environment relationships, enhancing the accuracy and reliability of predictions. Through a combination of user-friendly features and sophisticated analytical capabilities, EcoNicheS empowers researchers and conservation practitioners to effectively assess and mitigate threats to biodiversity in a rapidly changing world.
