Warm-Up15SEP2015 What makes the Haber-Bosch process so important? What are the other 2 ways to create “fixed “ nitrogen? Logistics: 10 vocab, celebration, and owl pellet lab is ALL due on Friday (FRQ for chapter 2/3 Monday) Ozone analysis is TODAY!

ENERGY FLOWS! (through ecosystems) – Open system MATTER CYCLES! (in the biosphere) – Closed system

A major part of DNA and ATP (in all living things) Is a limiting element in ecosystems Often used in fertilizer NO GASEOUS PHASE!! The Phosphorus Cycle

Calcium, Magnesium, Potassium, and Sulfur Cycle

All are essential for life processes All have no GASEOUS phase, but can be deposited by dust l

The Carbon Cycle

Photosysnthesis Respiration Exchange Sedimentation Burial Extraction Combustion Pre-industrial times, the carbon cycle was balanced. The Carbon Cycle

CaCO3

Human Altering of Carbon Cycle Combustion Deforestation

Things to do today… Ozone Lab for September (write in the same data table from last time-KEEP IT ALL YEAR!) Owl Pellet Lab 2.0 (there are multiple parts be sure to read ALL the directions) 10 Vocabulary Tuesday is afterschool APES time

Warm-Up16SEP2015 What are 2 ways human alter the Carbon cycle? How are the phosphorous and nitrogen cycle similar? Different?

DISTURBANCE = CREATION (in ecology) Disturbance- An event caused by physical, chemical or biological agents that results in changes in population size or community composition.

Disturbances Earthquakes, Fires, Tsunamis, Logging, Etc.

Resistance versus Resilience Resistance- A measure of how much a disturbance can affect its flows of energy and matter. Resilience- The rate at which an ecosystem returns to its original state after a disturbance..

Restoration Ecology Restoration ecology- A new scientific discipline that is interested in restoring damaged ecosystems.

The Intermediate Disturbance Hypothesis The intermediate disturbance hypothesis- states that ecosystems experiencing intermediate levels of disturbance are more diverse than those with high or low disturbance levels.

Lodgepole Pine vs Spruce Fir LP burns years SF burns years

Pre and post Katrina

Watershed Studies Watershed- All of the land in a given landscape that drains into a particular stream, river, lake or wetland. ALL the biotic and abiotic things that effect the watershed/landscape

Logging Mining Human Development Drought Recreation Etc.

Hubbard Brook Experimental Forest

Ecosystems Provide Valuable Services Services are connected to our economic system, through goods and services Services are our food Changes to the Ecosystem has ecological consequences, social consequences, and economical consequences

Instrumental Values of Ecosystems Provisions - Goods that humans can use directly. Regulating services- The service provided by natural systems that helps regulate environmental conditions. Support systems- The support services that natural ecosystems provide such as pollination, natural filters and pest control.

Resilience - Resilience of an ecosystem ensures that it will continue to provide benefits to humans. This greatly depends on species diversity. Cultural services- Ecosystems provide cultural or aesthetic benefits to many people. Instrumental Values of Ecosystems

Things to do today… Ozone Lab for September (write in the same data table from last time-KEEP IT ALL YEAR!) Owl Pellet Lab 2.0 (there are multiple parts be sure to read ALL the directions) 10 Vocabulary

Warm-Up17SEP2015 What is the intermediate disturbance hypothesis?

The Intermediate Disturbance Hypothesis The intermediate disturbance hypothesis- states that ecosystems experiencing intermediate levels of disturbance are more diverse than those with high or low disturbance levels.
