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

As a student at the University of Florida, you have committed yourself to uphold the Honor Code, which includes the following pledge: “We, the members of the University of Florida community, pledge to hold ourselves and our peers to the highest standards of honesty and integrity.”  You are expected to exhibit behavior consistent with this commitment to the UF academic community, and on all work submitted for credit at the University of Florida, the following pledge is either required or implied: "On my honor, I have neither given nor received unauthorized aid in doing this assignment." 
 
It is assumed that you will complete all work independently in each course unless the instructor provides explicit permission for you to collaborate on course tasks (e.g. assignments, papers, quizzes, exams). Furthermore, as part of your obligation to uphold the Honor Code, you should report any condition that facilitates academic misconduct to appropriate personnel. It is your individual responsibility to know and comply with all university policies and procedures regarding academic integrity and the Student Honor Code.  Violations of the Honor Code at the University of Florida will not be tolerated. Violations will be reported to the Dean of Students Office for consideration of disciplinary action. For more information regarding the Student Honor Code, please see: http://www.dso.ufl.edu/sccr/process/student-conduct-honor-code.
