Document Summary
Nuclear research also gave ecology tools and a model. Radioactive tracers allowed following fates of chemicals in natural communities. Manhattan project was the classic model for collaborative big science," a model that ecologists tried to follow with limited success. Nitrogen cycle (a gaseous cycle: human intervention: n fertilizer for crops. Anything that"s sugar based compound (anything with carbon) will be synthesized primarily by plants. Overall cycle we refer to as pools and fluxes are transitions in between (ex. Carbon cycle is the pool, and one flux is from human activity fossil fuels which accelerate fossil fuel pollution back into the atmosphere pool) Usually first nitrogen limitation and then p limitation. Imitating steps governing the carbon cycle the transfer by combustion/respiration from burning from fuel. Humans have land clearance, combustion of fossil fuels, extraction of fossil fuels. There"s a naturally recurring cycle where co2 from some communities, some run offs. Humans are just accelerating this natural set of pools.
