11. INTERDEPENDENCE All living and non-living things in an ecosystem are interconnected and changing even one thing impacts the whole ecosystem. When one tugs at a single thing in nature, he finds it attached to the rest of the world. ~John Muir, naturalist, Sierra Club founder

12. COMPETITION If resources are scarce, some organisms will starve and populations will decrease. If resources become more plentiful, populations will increase. Competition in nature often results in a winner and a loser... with the loser failing to survive!

13. If a nutrient is in _____________ OR __________________ it will LIMIT the growth of the population = _____________ LIMITING FACTOR SHORT SUPPLY CYCLES SLOWLY http://www.wspa-international.org/exhibition/gallery/large_DeadKenyan%20droughtSPANA.jpg During this drought, there was not enough food available and many kangaroos starved.

14. REMEMBER: EVERYTHING IS CONNECTED ! A decrease in the prey population means some predators will starve. Fewer predators mean prey population will increase. Increase in prey means more food for predators. Predator population will increase until there is not enough food... and the cycle repeats itself. BIOLOGY; MIller and Levine; Prentice Hall; 2006

15. LIMITING NUTRIENT When an ecosystem receives a LARGE input of limiting nutrient (ie.,fertilizer runoff) the population increases dramatically = ___________ http://www.greenfacts.org/images/glossary/algae-bloom.jpg The short supply of a limiting nutrient keeps the population in check.

29. Invasive Species An introduction

30. What is a native species? Native species are those that normally live and thrive in a particular community. They occupy specific habitats and have specific niches in their native environment. They have natural predators that help to keep their populations in check. Pink lady's slipper, Cypripedium acaule Red fox, Vulpes vulpes

31. What is a non-native species? A species living outside its native distributional range, which has arrived there by human activity, either deliberate or accidental. Non-native species are not necessarily invasive. Multiflora rose, Rosa multiflora, was introduced for use as an ornamental plant, to control erosion, and to use as “living” fences for livestock. Zebra mussels (Dreissena polymorpha), were accidentally introduced to North America, and are now found in some Pennsylvanian waterways

32. What is a non-native invasive species? A non-native species that adversely affects habitats and biodiversity. Emerald ash borer, Agrilus planipennis, has killed millions of ash trees in the mid-west and has recently been found in Pennsylvania Japanese stilt grass, Microstegium vimineum, becomes established on recently disturbed areas and outcompetes native plants, reducing biodiversity.

33. Common characteristics of invasive species Invasive species in general: Have few natural predators, competitors, parasites or diseases Have high reproductive rates Are long-lived Are generalists Are pioneer species Characteristics that make Zebra mussels a good invader include its ability to tolerate a wide-range of environments, and high reproduction rate; female mussels release up to 100,000 eggs ability to tolerate a wide-range of environments year. Discussion: how would these characteristics enable a species to become invasive?

34. What traits are common to invasive plant species Self-compatible Flower early Produces abundant seed Disperse seed widely Grow rapidly Spread asexually Strong competitors Characteristics that make tree-of- heaven a good invader include its ability to flower early (within 2 years), ability to spread asexually, and fast growth rate.

35. Kudzu Vine 1930’s - imported from Japan and planted in the southeastern USA to help combat soil erosion following the Dust Bowl. 1940’s – US Soil Conservation Service (federal agency) paid farmers a subsidy to grow kudzu vine. Problems: No natural predators, very prolific reproduction. Costs USA government $500 million/year to eradicate! Possible Commercial Uses: Chemicals produced in the vine are used in Japan to combat diseases. USA found chemicals in vine may reduce alcoholic cravings. May be a source for paper products!

37. Kudzu Vine Distribution in USA

38. Impacts of invasive species Displace native species Reduce forest health and productivity Some invasive species kill native species Indirect impacts Economic impacts: Invasive species are responsible for tremendous economic losses through loss in forest and agricultural productivity, spread of diseases that impact humans, among other impacts.
