What characterizes "Generalist species"?

• They occupy broad niches, eat a variety of food, and withstand varying conditions

• They occupy specific narrow niches, often with specific food sources

• They are the first species to colonize newly created environments

• They exert a large influence over an ecosystem and are depended on by many other species

What are "Genetic adaptations"?

• Changes in an organism's genetic makeup that occur over generations

• Variation of genes that exist within a species population

• Variations in ecosystems within a specific geographic area

What is the role of "Indicator species"?

• Alerts us to changes in the environment earlier than other species

• Occupy broad niches, eat a variety of food, and withstand varying conditions

• Exert a large influence over an ecosystem and are depended on by many other species

• First species to colonize newly created environments

What does "Island biogeography" state?

• Islands closer to mainland have higher biodiversity than smaller islands further from mainland
