Document Summary
Keystone species: species that have a domino effect on the entire ecosystem. Sea stars: prey on sea urchins, mussels, & other shellfish that have no other natural predators. If the seas star is removed from the eco. The mussel population explodes uncontrollably, driving out other species while the urchin pop. Bio mag: concentration of chemicals increasing with the position in the food chain. Large mouthed bass: mercury poisoning compared to smaller species down the food chain. Adaptive management: managing ecosystems within a given landscape in ways that enable rapid responses to changes in conditions. Nutrient cycle: nutrients are passed up the food chain. Nutrition for the biodiverse is provided from each other. Esa: protects species that are either endangered, threatened, or at the point of being. Species are watched and accounted for persistently and placed on a list protecting them from hunters or other human interruptions. Useful in cons: protects and restores biodiversity in this worl dinstead of ignoring.
