Global remotely sensed phenology of Blue-Green Ecosystems

 

Aquatic (blue) and terrestrial (green) ecosystems are closely linked through biogeochemical cycles and species that inhabit both ecosystems. Primary producers, such as algae and plants, form the basis of the ecological networks in both ecosystems. Using satellite remote sensing, we can observe seasonal cycles in primary production globally. As part of the Blue-Green Biodiversity initiative, we study this so-called phenology of lakes and watersheds across the past two decades. In particular, we study whether the phenology of primary producers has changed due to changing environmental conditions. We expect that blue and green ecosystems respond very differently to environmental change. This, in turn, may alter the links between both ecosystem types, and ultimately their species richness.
