EEPS course goals and objectives

Course Goals

All students will learn a toolbox of modeling approaches to describe and solve ecological and environmental problems.

Objectives

All students will demonstrate an ability to use modeling and simulation to solve ecological problems.

Course overview

The course will provide a general overview of the process involved in studying a variety of ecological and environmental problems. It will provide a toolbox of techniques for understanding ecological and environmental problems, and discuss how they can be used to address questions and generate testable predictions. It will examine connections between individuals and populations and communities as well as between theory and data. The focus will be on theoretical and computer modeling approaches, while maintaining a strong link to data and real systems.  After an introduction to modeling, students will learn to develop and use simple and stochastic optimization models for individual organisms, as well as applying basic game theory to interactions between individuals.  They will explore a sequence of population demographic models of increasing complexity, ranging from unlimited, unstructured population growth to density-dependent, structured population growth, in non-spatial and spatial contexts, culminating in individual-based models for population dynamics.  The students will then apply these models to interacting species, learning about mutualistic, competitive and host-natural enemy interactions.  Finally, we will explore theory for communities of species in space and time.  Applied problems will be drawn from all areas of conservation, harvesting, pest control and epidemiology throughout the semester.  No modeling experience is necessary as the course will start from basic principles.  

 

Prerequisites: BIOL 220W, any 1 semester Ecology course or permission of instructor.

Basic mathematical skills are also required (e.g. simple algebra).

Academic Integrity

Unless specifically directed otherwise, all assignments must be completed without assistance from others, except for guidance from Dr. Shea, the class TA, and/or guest instructors, and must represent your own work. PSU's Academic Integrity Policy is posted HERE. PSU’s Code of Conduct addresses personal conduct issues for students and their interface with the law, including harassment, sexual misconduct, drugs, alcohol, forgery, and misrepresentations of person.  See THIS LINK for more information (see point 10 for academic integrity). 

Our College, the Eberly College of Science (ECoS) has also adopted a “Code of Mutual Respect and Cooperation”. Students will be required to follow the guidelines concerning academic integrity as described in the Biology Department’s Policy and the Senate Policy 49-20

Weather delay policy

In years past, weather events have caused delays in the start of activities and classes at University Park campus. If a delay is announced at University Park, classes and activities that begin before the announced time are canceled.
 
Those classes or activities beginning at or after the conclusion of the announced delay time will be held as originally scheduled. For example, a two-hour delay until 10 a.m. due to snow or ice would mean that all classes that begin before 10 a.m. are canceled and will not be held. Classes beginning at 10 a.m. or later will continue on their regular schedule.
 
As this class runs across multiple periods, please note that CLASS WILL BE HELD if the delay only affects part of the class session.  So, class will start at the end of the announced delay time and continue through the end of the normal class period. For example, if a 3-hour delay is announced, class will start at 11 a.m.
