Key Concepts
|
Ecology focuses on how organisms interact with each other and their environment. The foundational ecological unit is the ecosystem. The key to understanding ecosystems is “connectivity”.
Ecology provides a scientific foundation for the conservation of species and habitats. Climate varies with latitude, elevation, and other abiotic factors. Climate is changing rapidly around the globe. In addition to abiotic aspects of the environment such as physical structure and climate, species distribution is constrained by historical and biotic factors. |

|
community
|
consists of the species that interact with one another within a particular area.
|
|
|
complexity-based approach or wholistic
|
This involves elements of reductionism and well as novel mathematical techniques that involve elements of non-random, yet not completely predictable, behavior called chaos and propensity (some event has a greater tendency of occurring under a given set of circumstances)
Ecological complexity has been recognized for many years but is still in its infancy |
|
|
Lakes and ponds have five zones of water depth:
|
-littoral zone
-limnetic zone -benthic zone -photic zone - aphotic zone. |
|
|
Wetlands
|
are shallow-water habitats where the soil is saturated with water for at least part of the year.
|
|
|
estuary
|
forms where freshwater mixes with salt water.
|
|
|
Biomes
|
are major groupings of plant and animal communities defined by a dominant vegetation type.
-Biomes are defined by the average annual temperature and precipitation -Each biome contains species that are adapted to a particular temperature and moisture regime. |

Tundra
Tropical Wet Forest Taiga (boreal forest) Desert Temperate Grasslands Savannah Temperate Rainforest Temperate Forest |
