Clarifying the driving mechanisms of spatial and temporal changes in regulating ecosystem service value (RESV) is an important part realizing goal sustainable development. Existing studies have focused on specific factors, ignoring complex interactions between factors their regional differences. In this regard, RESV its different zones (core area, fringe peripheral area) were explored Poyang Lake Area, China. The results showed that spatially distribution characteristics area > core while lakes influenced provision services, showing per unit was higher gradually declined with increase distance from lakes, presenting decreasing trend area. From 2000 to 2020, study lost 70.5988 billion CNY for RESV, which most affected. Further analysis mechanism areas found there are differences paths factors: Population density mainly affects precipitation GDP land

Abstract Since the active role of inland waters in cycling carbon (C) has been revealed, there a renewed interest calculating C budgets for to understand their with respect global climate change. There is lack knowledge regarding Laurentian Great Lakes, worlds largest freshwater reservoir, current estimates neglecting invasive species. For one most pervasive invaders, dreissenid (zebra and quagga) mussels, research focused on filter feeding impacts phosphorus dynamics, but cycling, specifically, impact stored slowly degrading shells. As such, we set out estimate mass empty shells those We calculated an estimated 1.19 E10 tonnes shell currently sitting at bottom these lakes, which store approximately 1.43 E9 C. This scale inorganic storage comparable rates organic nature-based solutions. work demonstrates importance previously unexplored pathway that mussels are altering Lakes thousands other invaded lakes rivers.
