1 Learning Targets “I can...” -Identify habitat fragmentation as having the most negative impact on biodiversity. -Define “deforestation” and its impact on biodiversity. -Give examples of events that destroy habitats and offer alternative solutions to those events. -Simulate how the number of species on habitat islands is affected by the area effect and the distance effect; closer and larger islands to the source population have more species.

2 Habitat Islands How do the size and distance of habitat islands affect species diversity?

3 Life Sciences - HHMI Outreach. Copyright 2010 President and Fellows of Harvard College Habitat loss is due to: Conversion of natural areas to farms, houses, etc Fragmentation of ecosystems by human activities, housing, transportation, agriculture etc. Simplification of genetic diversity and complex ecosystems by planting/selecting monocultures. Habitat loss is the greatest reason for biodiversity loss.

7 What is a Habitat Island? Natural habitats fragmented by human activities Habitats that are surrounded by a different type of habitat Animals and plants are often confined to their habitat island because the surrounding habitat is much like an unswimmable ocean
