Constructed wetlands (CWs) have emerged as multifunctional, nature-based infrastructures for the bioremediation of polluted water bodies. This review critically synthesises recent advances in CW design typologies, treatment mechanisms, and technological innovations, with particular emphasis on their strategic deployment as eco-buffer zones at watershed interfaces. Unlike existing reviews that treat CWs primarily as engineering...

Plant and animal community composition changes at higher elevations on mountains. Plant and animal species richness generally declines with elevation, but the shape of the relationship differs between taxa. There are several proposed mechanisms, including the productivity hypotheses; that declines in available plant biomass confers fewer resources to consumers, thus supporting fewer species. We investigated resource availabili...
