![]() ![]() ![]() It is a worthwhile exercise to imagine that something else, such as an ant, a lizard, an oak tree, or an HIV virus, is really the focus of the cosmos. From such a perspective, the almighty dollar quickly loses its primacy. Survival (Survival Kit) and reproduction assume a lot more significance. What good are lizards? Why should I take this course? Teaching Assistant: Ann Thijs annthijs@mail.utexas.edu ![]() ![]() Outline of Subjects to be covered in the Course Professor Eric R. Pianka Definitions and Groundwork; the scientific method; domain of ecology, environment; limiting factors, tolerance limits, the principle of allocation; natural selection, self-replicating molecular assemblages; levels of selection, levels of approach to science, speciation, phylogeny, classification and systematics. ![]() Macroevolution, natural selection and adaptation, the species concept. Origin of life, prokaryotes and eukaryotes, introduction to the diversity of organisms. Domains, traits (and example organisms) of kingdoms [archaebacteria, eubacteria, protists, fungi, plants, animals] Adaptations, structures, symbiotic relationships, including variations in life cycles How organisms are classified and why; phylogenetic systematics One major taxon will be examined in depth ( Lizards ); we will investigate classification, phylogeny, and biogeography Evolution will be related to the history of earth (plate tectonics) Physiological Ecology Physiological optima and tolerance curves, energetics of metabolism and movement; energy budgets and the principle of allocation; adaptation and deterioration of environment; heat budgets and thermal ecology; water economy in desert organisms; other limiting materials; sensory capacties and environmental cues; adaptive suites and design constraints. ![]() Principles of Population Ecology Life tables and schedules of reproduction; net reproductive rate and reproductive value; stable age distribution; intrinsic rate of increase; population growth and regulation; Pearl-Verhulst logistic equation; density dependence and independence; r and K selection; population "cycles," cause and effect; metapopulations; evolution of reproductive tactics; evolution of old age and death rates; use of space; evolution of sex; sex ratio; mating systems; sexual selection; fitness and the individual's status in the population; kin selection, reciprocal altruism, parent-offspring conflict and group selection. Interactions Between Populations Complex examples of population interactions; indirect interactions; competition theory; competitive exclusion; balance between intraspecific and interspecific competition; evolutionary consequences of competition; laboratory experiments and evidence from nature; character displacement and limiting similarity; future prospects; Predation; predator-prey oscillations; "prudent" predation and optimal yield; theory of predation; functional and numerical responses; selected experiments and observations; evolutionary consequences of predation: predator escape tactics; aspect diversity and escape tactic diversity; coevolution; plant apparency theory; evolution of pollination mechanisms; symbiotic relationships. Community Ecology Classification of communities; interface between climate and vegetation; plant life forms and biomes; leaf tactics; succession; transition matrices; aquatic systems; community organization; trophic levels and food webs; the community matrix; guild structure; primary productivity and evapotranspiration; pyramids of numbers, biomass, and energy; energy flow and ecological energetics; saturation with individuals and with species; species diversity; diversity of lowland rainforest trees; community stability; evolutionary convergence and ecological equivalents; ecotones, vegetational continuua, soil formation and primary succession; evolution of communities. Island Biogeography and Conservation Biology Classical biogeography; biogeographic "rules;" continental drift; island biogeography; species-area relationships; equilibrium theory; compression hypothesis; islands as ecological experiments: Krakatau, Darwin's finches, and other examples; metapopulations, conservation biology, human impacts on natural ecosystems, hot spots of biodiversity, applied biogeography and the design of nature preserves.
