Stuff you need to know – Week 9 Populations: definition of, density vs dispersal, reproductive strategies (semelparity vs iteroparity, seasonal vs continuous) Demography: factors that influence population size & structure over time Type I, II, III survivorship curves Survivorship & fecundity: definition of, relationship between. Life tables, survivorship, age specific fecundity, product of two, net reproductive rate (R0) Discrete growth rate (), instantaneous growth rate (r), relationship between two Intrinsic rate of increase (rmax) Exponential growth vs logistic growth, carrying capacity (K), logistic growth equation Density independent vs density independent factors regulating populations r vs K selected species Community ecology – species interactions Community: definition of, relative scale compared to populations & biomes Species interactions: direct interactions (5 basic types) Competition: definition of, concept of niche, competitive exclusion principle, fundamental vs realized niche, symmetric vs asymmetric competition Mutualistic interactions Antagonistic interactions/Consumption: herbivory vs parasitism vs predation, constitutive vs inducible defenses, mimicry (batesian vs mullerian) aposematism
