1 Ecology (BIOL 250) Lecture 23: Species Loss and Conservation Biodiversity Today s Outline Biodiversity Extinction Human Causes Conservation Biology Endangered Species act Announcements Number and variety of Earth s organisms Three components Genetic diversity Species richness Ecosystem diversity Biodiversity Why Do We Need Biodiversity? Ecological and agricultural processes Food, medicines Biological processes Organisms are interdependent Biodiversity - Ecosystem Services Environmental benefits provided by ecosystems Often taken for granted Biodiversity- Medicinal Value Extinction Species provide many medicines Rosy periwinkle: childhood leukemia AZT Early HIV drug Derived from a sea sponge Natural event & ultimate fate of all species 99% of all previous species are extinct But, currently accelerated by human activities Estimated at times natural rate 1

2 Extinct & Endangered Species Endangered & Threatened Species Where Is Biodiversity Declining? Endangered species Threats that may lead to extinction Numbers severely reduced Threatened species Declining population Could become endangered Genetic variability severely diminished Tropical rain forests Being destroyed faster than most other ecosystems United States Hawaii California Human Causes Of Species Endangerment Habitat loss Pollution Invasive species Species endangerment - Habitat Loss Destruction, fragmentation, degradation Largest threat to species Why is so much land being altered? Isolated patches often won t do Worldwide problem 2

3 Species endangerment - Habitat Loss Figure 22.4 Loss of Forest Cover in Western Ecuador Habitat degradation changes that reduce quality of the habitat for many, but not all, species. Habitat fragmentation breaking up of continuous habitat into habitat patches amid a human-dominated landscape. Habitat loss conversion of an ecosystem to another use. This process has led to the loss of over 1000 endemic species! Species endangerment - Pollution Acid precipitation Ozone depletion Climate change Direct or indirect poisoning Altered habitat from chemicals Species endangerment - Disappearing Frogs Amphibians Bellwether or sentinel species Provide early warning signs Many frog populations shrinking Worldwide problem Causes? Foreign species that cause economic or environmental harm Often introduced by humans: how? 3

4 Zebra Mussels Invasive species Introduced from ballast water into Great Lakes Cluster in high density Eat other species food Cost U.S. $5 billion per year Large predators are considered pests Carolina parakeet Southern U.S. Farmers disliked Extinct Passenger pigeon Unregulated hunting Extinct Poaching Illegal hunting Many large animals Bushmeat trade Overfishing in the oceans has led to declines in abundance and size of top predators. For every ton of fish caught by commercial trawlers, 1 to 4 tons of other marine life may be brought aboard, called bycatch. Bycatch includes many species of concern, including marine mammals, birds, and turtles. Trophy fishing off of Key West Florida: (a)1950 (b)1980s (c)

5 Conservation Biology Study of human impacts on organisms Development of ways to protect biodiversity Two techniques In situ conservation: preserving biodiversity in nature Ex situ conservation: conserving biodiversity in human-controlled settings Conservation Biology Protecting Habitats Best way to preserve biodiversity Problems Some too small, too isolated Not enough money Some not very species rich Areas of concern Tropical rain forests, deserts, islands Conservation Biology Restoration Ecology Study historical condition of humandamaged ecosystem Goal: return it to former state Creates habitat Very expensive Conserving Species Reintroducing Species Zoos, aquaria, botanical gardens Collecting eggs, seeds Captive breeding Expensive Difficult May not work Ultimate goal of captive-breeding programs One in ten successful: why? Must determine Why species was in trouble If trouble will reoccur If suitable habitat remains 5

6 Seed Banks Seed collections 100+ worldwide Over 3 million samples Kept at low temperatures Disadvantages Some can t be stored Expensive Stopping natural selection 1973 Legal protection to listed species Endangered and threatened Species get a plan for protection 2005: nearly 1300 species Critics Of The ESA Limits property owners rights Interferes with federally funded projects Impediment to economic progress Just keep adding more species Defenders Of The ESA Many development cases reconciled Has saved some species ESA needs strengthening Many species currently improving Future Of The ESA? Politically entangled since 1992 Give property owners more rights? Pay property owners for protection? Protect whole ecosystems rather than single species? Case Study: Wolves In Yellowstone Most gone in lower 48 by 1960: why? 1974: listed as endangered 1995: reintroduced to Yellowstone Population has thrived Prey populations in check Ecosystem healthier 6

7 Case Study: Wolves In Yellowstone Ranchers oppose: why? Compromise Ranchers can kill wolves that kill their livestock Federal officials can remove threatening wolves Ranchers reimbursed for losses Make Good Choices! Shade-grown coffee Forests not cut down Provides habitat Hand-picked Look for organic, fairtrade brands 7
