Ecology: Patterns and Processes
- Definition: The study of distribution and abundance of organisms; and factors/interactions that determine distribution and abundance (where are they, how many, and why?)
- History roots: Natural history, human demography, biometry, and applied problems of agriculture and medicine; including hunters and gatherers, Aristotle (350 BC - Historia Animalium), Herodotus and Plato (Providential ecology), Graunt (1662), Leeuwenhoek (1687 - population growth), Buffon (1756), Malthus (1798), Quetelet (1835), Verhulst (1838) and their relations to population regulation, Farr (1843), Edward Forbes (1887), Henry Cowles (1899), Ronald Ross (1908), A.G. Tansley (1904), F. E. Clements (1905), Charles Elton (1927) and Rachel Carson (1962)
- Factors: Abiotic factors (temperature, light, nutrients, water); biotic factors(other organisms, competition, predation)
Ecological Scales: Definitions & Levels
- Organism: A single individual;
- Population: Individuals of the same species living in the same geographic area
- Community: 2 or more interconnected populations
- Ecosystem: Comprises the community and its physical environment
- Biosphere: Regions of atmosphere, hydrosphere, and lithosphere where organisms live
Ecology: Statistical Approaches
- Methods: Statistics and scientific rigor; estimates of population parameters; random sampling; representative samples (and sampling error)
- The P-Value Approach: Hypothesis testing (null hypothesis and P-values); significance testing, generating p-values by comparing data wtih frequency distributions
- Z-Test Statistic: How many standard deviations a data point is above or below the mean
- Frequency Distributions: Determining probability (e.g., what is the probability of getting a > 75).
- Normal Distribution: Symmetrical, single central peak (mean), and spread determined by standard deviation.
Computational Set (Example)
- Practice Question 1: Z-test statistic (across Congo, typical termite capture by chimps is 100 with SD of 10; one troop averaged 96, is this less than the typical across the region?)
- Standard Error: SD of sample data /√N
- Z-score calculation (datum-mean)/ standard error
- Null Hypothesis: No difference in termite-capturing ability
- P-value and decisions on hypothesis/null hypothesis regarding results
