In this lecture you will:
|ECOLOGY – THE "STAGE" ON WHICH EVOLUTION
IS PLAYED OUT
AN ECOSYSTEM IS BOTH THE LIVING THINGS AND THE ENVIRONMENT
– examples: deer, rabbits, badgers, pine, oak, maples
- example: deer, the plants they eat, and the wolves that eat them, and the bacteria and fungi that break down the detritus
" thirty-three distinct types of natural
communities in Wisconsin—their characteristic trees, beetles, fish, lichens,
butterflies, reptiles, mammals, wildflowers—and the effects of geology,
climate, and historical events on these habitats. Part 2 describes and
maps fifty natural areas on public lands that are outstanding examples
of these many different natural communities: Crex Meadows, Horicon Marsh,
Black River Forest, Maribel Caves, Whitefish Dunes, the Blue Hills, Avoca
Prairie, the Moquah Barrens and Chequamegon Bay, the Ridges Sanctuary,
Cadiz Springs, Devil's Lake, and many others."
Wisconsin has a lot of variation in the land sculptured by glaciers, deposits of fertile soil in valleys and by streams and rivers AND by lakes, big and small
|What is an ecosystem?
Give some examples.
what is a population? Give some examples.
what is a species? Give some examples.
what is a community? Give some examples.
What is an environment? Give some examples.
What happens when two species DO have the same niche and habitat
1. direct, head on competition (war to
the end) ends in extinction for one.
2. partition resources (you get europe, I get the western hemisphere) (warblers in a tree)
3. symbiosis of some sort, provide something of value (lichens), cellulose breaking down bacteria in cows
|What is a habitat?
What is a niche? examples?
What 3 things may happen when two species try to occupy the same niche and habitat? Examples?
|"A biome is a climatically and geographically
defined area of ecologically similar communities of plants, animals, and
soil organisms, often referred to as ecosystems.
Biomes are defined based on factors such as plant structures (such as trees,
shrubs, and grasses), leaf types (such as broadleaf and needleleaf), plant
spacing (forest, woodland, savanna), and climate. Unlike ecozones, biomes
are not defined by genetic, taxonomic, or historical similarities. Biomes
are often identified with particular patterns of ecological succession
and climax vegetation.
The biodiversity characteristic of each biome, especially the diversity of fauna and subdominant plant forms, is a function of abiotic factors and the biomass productivity of the dominant vegetation. Species diversity tends to be higher in terrestrial biomes with higher net primary productivity, moisture availability, and temperature. CITATION"
