BI 143 : Habitats: Fresh Water Biology
Covers environments of freshwater streams, lakes, and marshes. Includes effects of physical and chemical factors on organisms, along with the organisms, their biological interactions and nutrient cycles. Explores ecological factors of freshwater environments and the effects of human activities on them.
Fieldwork is a professional competence in many areas of Biology. Standard field practices include measurements of abiotic and biotic components. Fieldwork includes use of all the senses to make observations in natural and built environments. Field training may include developing skills in site characterization, measurement and data collection, application of key terms and concepts, species identification, and observation. Certain protocols may require use of equipment, chemicals, and expensive gear. Field training is experiential often leading to unique sets of observations/data in particular locations. Fieldwork may include inherent risks (uneven terrain, off-trail work with map & compass, variable weather, insects, environmental irritants, travel, stress, etc.). Fieldwork can be physically challenging and may require overland travel on foot or unusual means to field points, carrying field equipment (as well as food, water, and safety equipment), taking measurements under duress (learning new protocols, requiring remaining in an unusual posture or position for a length of time, timing pressures for certain procedures, holding organisms, variable weather, etc.), survival skills, orienteering, and so on.
Equivalent placement test scores also accepted.
A student will collaboratively and independently:
- Use basic principles of ecosystems structure and function to characterize freshwater habitats.
- Identify and express how humans interact with the freshwater ecosystems by applying basic principles of environmental management.
- Identify and understand the biology of the various freshwater phyla.

To clarify the teaching of evolution and its place in the classroom, the Portland Community College Science Departments stand by the following statements about what is science and how the theory of evolution is the major organizing theory in the discipline of the biological sciences.
A. Science is a fundamentally nondogmatic and self-correcting investigatory process. In science, a theory is neither a guess, a dogma, nor a myth. The theories developed through scientific investigation are not decided in advance, but can be and often are modified and revised through observation and experimentation.
B. The theory of evolution meets the criteria of a scientific theory. In contrast, creation “science” is neither self-examining nor investigatory. Creation “science” is not considered a legitimate science, but a form of religious advocacy. This position is established by legal precedence (Webster v. New Lenox School District #122, 917 F. 2d 1004).
Science instructors of Portland Community College will teach the theory of evolution not as absolute truth but as the most widely accepted scientific theory on the diversity of life. We, the Biology Subject Area Curriculum Committee at Portland Community College, therefore stand with such organizations as the National Association of Biology Teachers in opposing the inclusion of pseudo-sciences in our science curricula.
