1)What components impact ecology? –

2. An ecological hierarchy is a natural organization of biological structures at different levels of scale and association b/w organisms and the environment -
3. An ecosystem is tied to a location with boundaries not just physical or geological -
4. An organism’s niche is dependent upon…
5. Individuals undergo interactions that can be classified as –
6. Organisms sometimes predate upon each other in order to express competition -
7. The decorator crab is an example of Crypsis -
8. Aposematic interaction refers to bright coloration related to warning coloration -
9. Responses to competition and predation can be –
10. In the “time spent in a patch” optimization rule –
11. The size of a prey organism can be critical to optimal foraging theory; large prey with lots of nutrients can

be unduly hard to eat -

12. A particular parasitic barnacle is known to invade inside a crab and live in a crab’s body -
13. A small fish lives in the same hole as a worm, the worm gives protection, the fish brings in food –
14. A population is a group of individuals that are affected by the same overall environment and are strongly

connected with other populations of the same species -

15. Allopatric speciation arises as a result of geographic isolation -
16. Population models can take into account every possible characteristic of a pop, such as its size, the reproduction rate, the emigration rate, and time but in many cases only 2 or 3 characteristics need to be included; all dependent upon the biology of that particular organism -
17. When is mortality most likely to be intense in the life of a marine organism –
18. A metapopulation is an interconnected group of approximately equal subpopulations -
19. In the example discussed in class, parasites greatly affected the distribution of adult snails in mangrove forests. This was an example of the effect of density and the type of distribution of the niches. -
20. Communities involve different pops in a given specific habitat. A critical feature of many communities is

the presence of a foundation species. –

21. Space is commonly a limiting factor in communities; lack of space can drive competitive displacement, where one species out-competes another. The winner is called –
22. In scramble competition –
23. Competition networks can create unexpected outcomes because of complexity of interactions between species –
24. In the intermediate disturbance –
25. Succession models suggest that for a given environment, there is usually a given particular series of intermediate stages -
