Influence of eutrophication on disease-vectoring mosquitoes in grassland agricultural landscapes: Processes, patterns, and predictions

Landscape alterations and disease emergence are environmental concerns that intersect at aquatic ecosystems. Eutrophication of aquatic systems is attributable to fluctuating biogeochemical cycles linked to the anthropogenic activities of grassland agricultural landscapes. Impaired hydrogeomorphology and riparian habitat exacerbate the situation by disconnecting aquatic systems from natural floodplains and, in turn, produce nutrient-enriched aquatic habitats for bacteria species assemblages that often influence disease-vectoring mosquito spatial distribution and pathogen transmission in grassland agricultural landscapes. This study examines the broad-scale patterns of nutrient transition over grassland agricultural landscapes to better understand the influence of landscape management strategies on biogeochemical cycles and subsequent effects on infectious disease ecology.
