ABE 6933
Seminar on stochastic modeling in ecology and hydrology

Semester Taught - Fall

Catalog Description

Credits: 3

This course takes a problem-based approach to introduce stochastic modeling in context of ecology and hydrology.  The students will be asked to study selected papers in detail, through reading and in-class discussion, such that they understand how to set up the problems and derive some results and mathematical expressions reported therein.  In the first few lectures, some basic concepts in probability and stochastic processes will be discussed.  During the first part of the course, the instructor will lead the discussion.  Afterwards, the students may take turn to lead the discussion.  Depending on their interest and progress, the students may suggest papers on stochastic modeling in the field related to their own research during a later phase of the course.  Examples of topics to be covered include neutral model of biodiversity (in which birth, death, dispersal, and speciation are stochastic), soil moisture dynamics driven by stochastic (Poisson) rainfall, stochastic models of rainfall (pulse model), etc.

Pre-requisites/Co-requisites

Graduate standing; basic calculus and college-level probability courses

Course Objectives

  • After taking this course, you should:

    • Understand and be able to derive the basic results in the papers covered in class.
    • Be able to apply these techniques to similar problems.
    • Be able to formulate problems and construct models to study the effects of stochastic fluctuation on the resulting outcomes.

Academic Honesty

All students admitted to the University of Florida have signed a statement of academic honesty committing themselves to be honest in all academic work and understanding that failure to comply with this commitment will result in disciplinary action. This statement is a reminder to uphold your obligation as a UF student and to be honest in all work submitted and exams taken in this course and all others.

Accommodation for Students with Disabilities

Students requesting classroom accommodation must first register with the Dean of Students Office. That office will provide the student with documentation that he/she must provide to the course instructor when requesting accommodation.

Use of Library, Personal References, PC Programs and Electronic Databases

These items are university property and should be utilized with other users in mind. Never remove, mark, modify nor deface resources that do not belong to you. If you're in the habit of underlining text, do it only on your personal copy. It is inconsiderate, costly to others, and dishonest to use common references otherwise.

Software Use

All faculty, staff and students of the University are required and expected to obey the laws and legal agreements governing software use. Failure to do so can lead to monetary damages and/or criminal penalties for the individual violator. Because such violations are also against University policies and rules, disciplinary action will be taken as appropriate. We, the members of the University of Florida community, pledge to hold ourselves and our peers to the highest standards of honesty and integrity.
