419 Lecture Anthropogenic Impacts Study Guide Reading 3 posted papers posted slides Terms to Define Anthropogenic Impact human influence in the environment Trophic Cascade occur when predators in a food web suppress the abundance of their prey thereby releasing the next lower trophic level from predation or herbivory ifthe intermediate trophic level is an herbivore Ecosystem Engineer An ecosystem engineer is any organism that creates or modifies habitats Synergistic Effect effects of a combination of two or more substances that are greater than the sum ofthe effects ofthe individual substances Very little is known about the synergistic effects of our exposures to common chemicals Ocean Acidification The process by which the ocean s pH is lowered which increases its acidity Coral Bleaching The loss ofcolor in coral reeforganisms that causes them to turn white Coral bleaching is caused by the removal or expulsion ofthe coral s symbiotic zooxanthellae algae in response to high water temperatures or other adverse conditions Global Warming A gradual increase in the overall temperature of the earth39s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide CFCs and other pollutants Invasive Species Any species that has been introduced to an environment where it is not native and that has since become a nuisance through rapid spread and increase in numbers often to the detriment of native species Eutrophication The enrichment of waters by a previously scarce nutrient Pteropod An order ofpelagic gastropods in which the foot is modified for swimming and the shell may be present or absent Name 5 ofthe biggest impacts humans have on the marine environment Global warming pollution eutrophication overexploitation syngergisitc effects impacts facilitate or exacerbrate futher impacts Every anthropogenic impact builds on the ones before and concurrent it What is ocean acidification What causes it How are calcifying organisms affected How can marine food webs be impacted Ocen acidification is excess 002 in the atmosphere absorbed by the oceans Lowering the pH of the ocean acidifying it effects the ocean s acidi cation

pressure Subduction zone A long narrow region beneath Earth s surface in which subduction takes place Deep biosphere The microberich region beneath the sea oor Taxa to know key characters of taxonomy

barnacles copepods lobsters crabs and shrimp Echinoderms Phylum ofanimals that have bilateral symmetry in larval forms and usually a ve sided radial symmetry as adults Benthic and possessing rigid or articulating exoskeletons of calcium carbonate with spines this phylum includes sea stars brittle stars sea urchins sand dollars sea cucumbers and sea lilies Kelp large varieties of Phaeophyta brown algae Lobster large marine crustacean considered a delicacy Homarus americanus American or Maine lobster possesses two large chelae pincers and is found offshore from Labrador to North Carolina Various species of Panulirus spiny lobsters or rock lobsters have no chelae but possess long spiny antennae effective in warding offpredators P argus is found offthe coast of Florida in the West Indies whereas P interrupts s common along the coast ofSouth California Scleractinian stony corals order 0 cold and deep more diverse than tropic Octocoral sub class contains SCLI artipatharia and
