Last New Topics from the Green Packet Read this PowerPoint and take notes on it. Research any topics that you do not understand. Good luck tomorrow!
Competitive Exclusion Principle No two similar species can occupy the same niche at the same time
Interspecific Interactions Symbiotic Interactions Competition (-/-) Predation (-/+) Parasitism (-/+) Mutualism (+/+) Commensalism (+/0) Amensalism (0/-) Can you describe each of these interactions? Can you give an example?
Identify each of the following symbiotic interactions Identify each of the following symbiotic interactions. Write down your evidence for your answers.
sorry, bug…
Interspecific- competition between members of two different species Intraspecific- competition between members of the same species
What is this an example of?
What is this an example of?
Isolations behavioral isolation geographic isolation When the members of two populations cannot interbreed and produce fertile offspring, reproductive isolation has occurred. Reproductive isolation can develop in a variety of ways, including: behavioral isolation geographic isolation temporal isolation
Behavioral Isolation Behavioral isolation occurs when two populations are capable of interbreeding but have differences in courtship rituals or other reproductive strategies that involve behavior.
Geographic Isolation Geographic isolation occurs when two populations are separated by geographic barriers such as rivers or mountains.
Temporal Isolation Temporal isolation occurs when two or more species reproduce at different times.
Limiting factors Density-dependent limiting factors include: competition predation parasitism disease Examples of density- independent limiting factors include: unusual weather natural disasters seasonal cycles certain human activities— such as damming rivers and clear-cutting forests
Exponential Growth- is this realistic? Why or why not?
Logistic Growth- is this realistic? Why or why not? What is carrying capacity?
Make sure you can analyze these diagrams.
