Final EEB Test

Acclimation

Short term physiological changes in responses to changes in environment

What is an example of Acclimation

Woody plants increase hardiness: acclimate to/triggered by cooler temps and shorter photoperiod

Adaption

long term, genetic traits

What is the thermal neutral zone?

Temp range in which organism can maintain physiological rates via regulation of heat

What are some strategies that plants or animals have for staying warm in cool environments?

Fur, feathers, shelter, group huddle, brown fat

What are some strategies that plants or animals have for staying cool in hot environments?

sweating, radiating heat, panting

How did the finches (from discussion) maintain body temperature despite external extremes? 

They would shiver, fluff their feathers, metabolic adjustments and acclimate

How is water balance regulated

osmosis

What is C3 photosynthesis

normal photosynthesis

what is C4 photosynthesis

spatial separation of 2 carbon fixation paths

what is CAM

crassulacean acid metabolism: temporal separation of 2 carbon fixation paths

 In what kinds of environments would you expect to see C3, C4 and CAM adaptations?

C3 would be in normal plants

C4 and CAM are used to conserve water

How might the structure of the environment (e.g. distribution of soil nutrients and moisture) affect the patterns of distribution in plant and animal populations?

1. Environmental structure creates physical opportunities or limits growth.

2. Interactions shape how tightly or loosely individuals and species arrange themselves in response.

Niche

sum total of all the ways a species utilizes the resources of it’s environment

INTRAspecific

competition between individuals of same species

INTERspecific

competition between individuals of different species

secondary metabolism

• defense against predators and pathogens

• improve competitive ability

• reinforce interactions with other oganisms
