Ecosystem's and Biodiversity
Terms
Species Richness
A lot of different species high richness= high number
Population
total number of different alleles in a population
Genetic Diversity
The number of different Alleles in an ecosystem
Ecosystems
Interaction between living and non living parts of ecosytems
Relative Abudance
How common or rare a species is
Community
total number of living species
Qualitative data
a number or list of species present
Quantitative Data
The number of each species
Abiotic factors
Light intensity
For photosynthesis,influences primary productivity
Temperture
All organisms are affected by temperature, affects enzyme activity, therefore affects metabolism
Wind
Accelerates rate if evaporation, therefore transcription
Salinity
Affects osmosis, therefore water availibilty
Water avabily
All living organisms require water
Oxygen concentration
Essential for all aerobic organisms
Humidty
It affects the rate of transpiration in plants
pH
Afffects enzyme activity, therefore affects metabolism
Sampling
Qualitative Sampling
Qualitative sampling is a list of species present during sampling fieldwork,this is the case for all terrestrial and aquatic sampling
Identification in sampling is key to getting exact and informative data
Quantitative Sampling Techniques
Simpsons Diversity index is used to calculate the degree to which an area is considered diverse compared to another area
Simpson's Diversity index
Used to calculate the degree to which an area is considered diverse compared to another area
Relates to the number of individuals of a kind to the total number of individuals
Lincoln Index
A way to estimate the population size of an animal species is using the capture mark recapture
