Outcomes and Objectives:
At the conclusion of this course, the student should be able to:
Untitled document
Upon completion of this course, students will be able to:
1.  Apply methods of science and scientific investigation.
2.  Analyze the basic principles and assumptions of ecology, including the
   the cellular nature of life, correlation of structure and function,
   energy transformation, growth and development, evolution and
   characteristics of systems.
3.  Evaluate the relationship between physiological and anatomical
   adaptations of plants, animals, and aquatic organisms to environmental
4.  Examine the limiting factors for species and their effect on species
   distribution and community ecosystem structure.
5.  Examine the basics of biosphere processes (climatic, physiographic, and
   biotic) and apply this knowledge to understanding the distribution of major biomes.
6.  Diagram ecosystem structure and function, including trophic structure
   and function, productivity, and mineral cycles.
7.  Examine current global and ecosystem level environmental problems, and
   synthesize the application of ecosystem studies to their solutions
8.  Examine community ecology, including competition, species
   interactions, diversity, stability, vegetation ecology, island
   biogeography, ecological succession and its application to current
   issues park/preserve design, restoration, reforestation,
9.  Analyze population dynamics including patterns of distribution and
   dispersal, age structure, growth, "r" vs. "k" characteristics,
   interspecific and intraspecific factors and apply these concepts to
   human population dynamics.
10. Synthesize the interplay of economic and ecological considerations for
   managing biosphere resources with examples in ecosystem management
   (e.g., forests, rangelands, wetlands, endangered species and the
   maintenance of biodiversity).

Topics and Scope
Untitled document
A.  Ecology as science:
   1. Ecology as a subdivision of biology
   2. Scientific approaches to problems - science as a way of knowing.
B.  Foundational principles
   1. Cellular and chemical nature of life: basic chemistry, properties
      of water, overview of cell structures and functions
   2. Structure and function; physiological and anatomical adaptations
   3. Energetics; photosynthesis, cellular respiration, laws of
   4. Growth and development
   5. Evolution: species adaptations, speciation, evolution of ecosystems
   6. Characteristics of systems
C.  Adaptations of plants, animals, and aquatic organisms
   1. Limiting Factors
   2. Species distribution
   3. Community and ecosystem structure
D.  Biosphere structure and function
   1. Climate: precipitation, temperature, climatic zones, climate change
   2. Effects of climate on biogeography and formation of major
      landscape types (biomes)
E.  Ecosystem structure and function
   1. Principles of cycle and flow
   2. Trophic structure: productivity, energy flow in ecosystems, food
      chains and webs and ecosystem structure.
   3. Mineral cycles: carbon cycle, nitrogen cycle, water cycle.
   4. Issues in ecosystem resource management: global warming, water
      availability, water quality and pollution, human food supplies and
      sources, application of ecosystem studies to agriculture
F.  Community structure and function
   1. Interspecific competition: habitat and niche, competitive
      exclusion, resource partitioning
   2. Species interactions: predation, parasitism; mutualism, herbivorey,
      commensalism and coevolution.
   3. Diversity, dominance, complexity, stability, resistance and
      resilience: applications to resource management and tropical
   4. Vegetation ecology: community structure and landscape ecology
   5. Island biogeography: species diversity, migration, extinction and
      replacement rates, and applications to biodiversity, conservation
      biology and preserve/park design.
   6. Ecological succession: primary, secondary, mechanisms of
      successional change, applications to restoration (reforestation,
      mining, agriculture, etc.)
G.  Biodiversity: genetic, species, community, ecosystem, alpha, beta
   and gamma levels of diversity
H.  Population structure and function
   1. Patterns of distribution and dispersal
   2. Age structure and life tables
   3. Population growth, exponential, density dependent and density
      independent growth limits.
   4. Dynamics of "r" and "k" selected species
   5. Applications to human population dynamics and resource management.
I.  Management and conservation of natural resources
   1. General principles of sustainable resource management
   2. The interface of ecology and economics
   3. Ecosystem management case studies e.g., forests, rangelands,
   4. Importance and maintenance of biodiversity: endangered species and
      ecosystems, and management for conservation.
