Notes

1. Biosphere is a group of ecosystems
2.Indicator species- species that indicates something, birds flying away before a hurricane
3. Gauses principle-two populations competing for the same resources cannot sustain the same pop levels that were there before hand.
4.Migrate
5. Migrate, die, or adapt
7. species richness- number of species in an area, species eveness- proportions of species in an area. Eveness is better becuase it provides less competition.
8. Tropical, marine estuaries and swamps/marshes
9. Theory to explain richness of islands
10. One large reserve is better than multiple small
11 One Large
12 to stop the cane beetle from eating the sugar stalks
13 They have different adaptations because they come from other places
14 They were outcompeted for resources
15 Clumped- Wolves are clumped together for protection
Uniform (Evenly dispersed)- Penguins that are hatching eggs are uniform because they want space
Random- the organisms do not interact with each other
16 P=Poer^t
19 Biotic Potential, exponentail growth, carrying capacity environmental resistence
22 Density independent- weather natural disasters
Density Dependent- predation
24 Persistence is to resist change, resilience is to recover from change
25 Functional is the range of things that the organisms do
30 Phylogeno tree shows evolutionary path
31 Sympatric speciation is inbreeding
Allopatric is when geographic and then reprductive
Parapatric is change in habitat
38 Background Extinction - normal extinction rate
39 5
40 Species in one geographic region-
41 They can be wiped out easily
42 Micro happens within one population Macro happens across species
43 climate change pollution habitat destruction
