Week 7 Flashcards
Three types of adaptation
- Biological adaptation
- Physiological adaptation
- Cultural adaptation
Fitness
A measure of preproductive success of individuals
Glogers rule
Within the same species, there is a tendancy for more heavily pigmented populations to be found towards the equator.
Bergmanns rule
Within the same species average weight tends to increase and surface area decrease in the average invornmental tempatures
(Bergmanns, B for Body)
Allen´s rule
Within a species the size of protruding body parts and lenght of arms and legs increase with increases of average enviornmental temperature.
(Allen, A for Arms)
Wich one is Bergmenn´s rule and which one is Allen´s rule?
Development adjustments
Process in which an organisim, during the course of its lifetime, can respond to changes in the enviornment. These changes tend to be long term and nonreversable.
Acclimatory adjustments
Short term responses to new enviornmental stresses. These tend to appear quickly and are reversable
4 enviornmental stresses
- Solar radiatin
- Cold stress
- Heat stress
- high altitude stress

Taxonomy
The science of the classification of living organisims, including principles, procedures and rules.
Homology
Structures of similiar in form and or charactoristics in two or more groups of organisims and ar the result of inheratence in ancestors.
Analagous structures
Structures similiar in form and or function in two or more groups of organisims but are not the result of common evolutionary history.
three types of evolutionary patterns.
What are the three rules of taxonomy
- Binomial nomenclature
- Law of Priority
- Law of type
Binomial nomenclature
Each species identified by two names
- Genus
- Species
What is this type of diagram called?
Cladogram
