    “Biogeochemical cycles” used to be a phrase that sent me running for the coffee. I know that understanding biogeochemical cycles will make me a better ecologist, and that biogeochemical cycles are fundamental for getting the big picture. Unfortunately, every time I tried to learn more about the subject, I ended up getting lost and bored in the seemingly endless web of arrows and equations. Biogeochemical investigations of sediment cores recovered by OGCP help characterize short-term changes in the depositional environment of lake Olduvai, including variations in terrestrial vegetation (grassland to woodland) and in aquatic biota perhaps linked to nutrient supply.

    Here biogeochemical analysis of a lake sediment core from southeast Greenland is used to define changes in moisture balance and runoff during the Holocene in a catchment near the margin of the Greenland Ice Sheet. A m sediment core that spans the last ka was recovered from Flower Valley Lake on Ammassalik Island. A food web (or food cycle) is the natural interconnection of food chains and a graphical representation (usually an image) of what-eats-what in an ecological ogmaexpo.comr name for food web is consumer-resource ogmaexpo.comists can broadly lump all life forms into one of two categories called trophic levels: 1) the autotrophs, and 2) the heterotrophs.

    Freshwater lakes provide an ideal example for considering the carbon cycle and other biogeochemical cycles. A range of redox conditions exists in lakes that allows observation of numerous chemical and biochemical processes. The processes are not limited to freshwater lakes, and similar examples can be found in marine and terrestrial systems. Jan 09,  · Some of the most chronic blooms are occurring in Lake Erie, Cape Fear River, Patos Lagoon Estuary in Brazil, and Lake Taihu in China. For the study, Lapointe also utilized data from several Land Ocean Biogeochemical Observatory (LOBO) units installed in the St. Lucie Estuary. The LOBOs are a significant monitoring network in the Indian River.
