What does Env. change = Habitat Disruption
Major environmental disturbances result in widespread habitat changes and or loss
Why might migration occur
Wildlife may migrate to a new habitat as the result of natural disruptions
Zonation
Spatial pattern of organisms over an area
(like band kid groups in sections)
Types of succession
Primary and Secondary
Where does Primary start
Bare rock
Where does secondary succesion start
Soil left over
Which goes faster and why
Secondary because it starts with a base of soil
Pioneer species/ early succession species
appear first, when the ground is simply bare rock, or bare soil after a disturbance
Mid-successional species
appear after pioneer species have helped develop deeper soil with more nutrients by their cycles of growth/death
Climax community species (late succession)
appear last, after soil is deepened and enriched with nutrients by cycles of growth and death by early & mid successional species
What composes Complexity
Resilance & Diversity
Endemic species
Native to a single geographic location or only found in one part of the world
Keystone species
Plays a critical role in maintaining the structure of the ecosystem
Flagship (umbella) Species
Instantly recognized and popular to humans
Biology practices that help animals not be extinct
Preservation Biology –
Attempts to exclude human activity in areas where humans have not yet encroached
Conservation Biology –
Sustainable use and management of natural resources
International Union for Conservation of Nature
Compiles data/resources from other organizations and experts to create the Red Data List & safeguard diversity.
World Wildlife Fund
Nonprofit that conducts research, provides public education & resources, provided funds for conservation efforts
CITES
Wildlife conservation agreement that ensures international trade of wild animals & plants does not threaten their survival
Endangered Species Act
Government act that prohibits harming of species, determines which species are endangered, & provides funds to purchase conservation habitats
