EVR 1001 Lecture Notes - Lecture 7: Carrying Capacity, Phenotype, Species Richness
Document Summary
Biodiversity is very beneficial to the world. Almost all medicines come from or are modeled after plants (ex. Ecosystem diversity: a diverse range of ecosystems across a given region. Ucf has about 13 different types of ecosystems. Species: organisms that share genes and can reproduce with each other. Genetic diversity: diversity in the genome; can be shared across species. Species richness: number of species in a given area. Species evenness: the relative abundance of the different species in an area (dominance) Usually just a few dominant species in an ecosystem. Evolution: the genetic composition of a species changing over time. Macroevolution: evolution that gives ride to new species or larger groups (genera, family, class, phyla) Evolution happens through dna (a, c, t, g) Gene: hereditary unit representing a dna sequence on chromosomes in cell nucleus. Code for inherited traits (from mother and father) Genotype: complete set of genes in an individual. Genome: all the genes within an organism.
