Mountain vipers of the genus Montivipera, generally, and the species of the Raddei clade, specifically, are interesting examples of species neo-endemism in Iran, Anatolia, and the Caucasus. Given the critical conservation status of these species, it is necessary to identify their suitable habitats for prioritizing conservation measures. We modeled ecological niche of each species based on four ...

Ecological assembly is a fundamental and yet poorly understood process. Three main obstacles hinder the development of theory assembly, when these issues are sidestepped by making strong assumptions, one can build an graph in which nodes ecological communities edges invasions shifting their composition. The then be analysed directly, without need to consider dynamics. To showcase this framework...

in the regulated nakdong river, algal proliferations are annually observed in some seasons, with cyanobacteria (microcystis aeruginosa) appearing in summer and diatom blooms (stephanodiscus hantzschii) in winter. this study aims to develop two ecological models forecasting future chlorophyll a at two time-steps (one-week and one-year forecasts), using recurrent neural networks tuned by genetic...
