Fires, floods, droughts, and disease outbreaks 2. sea level 3. Earths Climate has changed over time, but for many reasons ECOLOGICAL SUCCESSION. 1. - Succession is the gradual change of species diversity, usually after disturbance. 2. There are 2 types: regulation regulation regulation PRIMARY • soll made by mosses/lichens Peroding rock. (long time!!) SECONDARY •soil already ex1545 Cand climax Community is reaches soonLY 3. Keystone species- Specles whose activity plays significant role in community Structure Indicator species-plant or animal that indicate certain qualities of an ecosystem Pioneer species - first species to move into unoccupted habit UNIT 2 EXTRAS Keystone Species diagram: of thot sodni Biodiversity WORD species Founder eveness Ecosystem Services effect Population the ecosystem bottleneck with wolves A AKA vocabulary: DEFINITION without wolves ge distribution of abundance across species in an area PROVISION ING definition: products obtained from ecosystems ******* 0 reduced gene diversity + population after new pop. by individuals Sharp reduction in population after ecosystem disturbance SUPPORTING definition: Services necessary for Production of all other services ex organic products, medicine anthro. disturbance: dumping of toxic waste into lakes limits Fresh water use EXAMPLE • Forest have many Species but few of each. • Pilgrim migration •honting species too much. (elephants) REGULATING definition: benefits obtained from the regulation of ecosystem processes. ex: pollination, desease control anthro disturbance: killing of of destroying habitat ilmits pollination baes COLTORAL definition: nonmatenal benepi45 obtained from ecosystems ex: carbon cycle, photosynthesis ex: aestheties, tourism ADI deforestation creates photo syntes is AB overhonting extinction ? problems which limit our oxygen no education on them UNIT 2: EXTRAS - ANTHROPOGENIC DISRUPTIONS 1. Extraction, transport, use of fossil fuel ECONOMIC CONSEQUENCES ECOLOGICAL CONSEQUENCES ECONOMIC CONSEQUENCE -Increase of respitory Illness, illness = expencive Ecological Consequences ·Polluted airlwater from burning 2. Air Water Pollution 1 oil spills+ fuel decrease in biodiversity -expensive to clean - Increase or respitory illness or cancer - decrease in biodiversity - decrease in available freshwater + toxi water
