Climate change case study

TED-Ed video showing how climate change can cause a rippling effect.

Review resources for biogeochemical cycles

Biogeochemical cycles

General review of some of these cycles: Learner.org.
Scitable provides a good jumping off point for exploring many topics related to Ecosystems Ecology.

Other very useful links - some of which have interactive components:

• Carbon cycle
• Nitrogen cycle by Vision Learning
• Nitrogen cycle by Bernhard

Nutrient Budgets, Inputs/Outputs

Nutrient budget components in terrestrial and aquatic 
ecosystems.  Inputs = blue, outputs = black. 
(Fig. 11.12, Ch. 11, Essentials of Ecology by Townsend et al). 

Nitrogen

Nitrogen cycle schematic (Harrison, 2003)

Phosphorous
Check out this narrated and animated video of the P cycle .   
Note, the animation does not go into depth about mineralization/immobilization.

Phosphorus cycle (Learner.org)

How does pH affect phosphorous availability (figure below)? Read about it here.

Human influences on nutrient cycling

A comparison of major nutrient pathways and how human 
activities influence these processes. Maroon arrows = human 
activities; dashed lines = insignificant pools and fluxes. 
(Fig. 11.16, Ch. 11, Essentials of Ecology by Townsend et al.)

Additional community ecology review resources

Here are a few more resources as you review community ecology...

Island Biogeography 

Visit this webpage, take the colonization simulation for a test "run", and then quiz your knowledge at the end with the Q & A!









Shannon Diversity Index

A website by M. Gregory provides a good review of how to calculate the Shannon diversity index (A.K.A. Shannon Weaver or Shannon-Weiner).
