Ecology : study of interactions between organisms and their environment Environment : all factors outside the organism; biotic and abiotic Proximal Patterns : can be explained by present environment (weather influencing plant growth) Ultimate Patterns : can be explained by past environment (ecological experiences of ancestors through evolution) Scientific Process : 1. Observation/Discovery 2. Question 3. Hypothesis 4. Test (observe, experiment, or mathematical modeling) 5. Conclusion 2 | P a g e Null hypothesis : no change or relationship Alternate hypothesis : Prediction of change or relationship Population : -a group of individuals of one species living together -where evolutionary change occurs/is revealed Homozygote : has the same alleles at a particular locus on the pair of chomosomes Heterozygote : has different alleles at a particular locus Alleles : two or more alternative forms of a gene Genotype : all genetic characteristics of an individual 3 | P a g e Phenotype : -interaction of the genotype of an individual with its environment -how the genetic instructions are expressed Phenotypic Plasticity : ability of individual to change its phenotype in response to changes in environmental conditions PP discrete forms : When phenotype can be expresses as one of two (or more) options, depending on the environment. (ex. bees) PP continuous forms : When phenotype has a range of how it can be expressed depending on the environment (ex. size of fish depending on food available) Evolution : change in the genetic composition of a population of a species over time Adaptation : change in a genetically determined trait in response to environmental conditions that enhances the ability to cope with the envir
