GOALS: This class is intended to provide the following:
1. In-depth understanding of the major areas of population ecology, including demography, single-species population dynamics, density-dependent regulation of populations.
depth understanding of interactions between pairs of species,
including competition, predation (and disease if time allows).
introduction to other areas of ecology, such as community
ecology (diversity and stability, island biogeography,
succession), ecosystem ecology (carbon cycles) behavioral
ecology (territoriality, optimal foraging), and evolutionary
ecology (life history trade-offs).
4. The first
three goals are content-oriented. In addition, the
class has three process-oriented goals:
Hours & Location: 2:10 - 3:00 MWF, 339 LEON JOHNSON HALL.

Office Hours: MW 10:30 -12:00 or by appointment. If these hours are not convenient, please talk to me after class to arrange another time and we will figure something out. I almost always have time for questions right after class. You're also welcome to email questions (but if you email me just before a test, I might not read it in time).
Text: Elements of Ecology, 8th edition by Smith &
Smith is required. Any other reading will will be posted
via links to pdf files on this web page.
notes: are available
from the links below. I will update these regularly
throughout the semester.
Overheads: the figures that I use in overheads are posted as pdf files in the links below. I occasionally add new material at the last minute, to incorporate new studies, but most of the overheads are in the pdf file links.
%. (Exam 3 will fall in finals week.
A small part of it will be comprehensive, but it will
primarily cover new material) The tests
will mainly be multiple choice questions and perhaps some short
answer. For some material, the tests involve doing calculations,
so bring your calculator on exam days.
Problem sets and/or quizes on computer exercises: 25% Several subjects will include short homework assignments. In these, you will use the methods described in lectures to test ideas with computer simulations of population dynamics or interactions between species. In some cases, a graded homework assignment or a short quiz will be based on the computer exercise. Together, these homework assignments account for 25% of the grade. Doing one optional HW assignment will allow you to drop your lowest HW grade.
Computer Exercises: Some homework assignments will use the
software packages GenX and POPULUS to examine evolution,
population growth, and interactions among species (such as interspecific competition and
predation), in a series of computer labs. POPULUS has simple
simulations that allow you to manipulate the variables in
mathematical models of ecological processes, and see the results
graphically. GenX lets you manipulate evolutionary forces
in two populations. Both are free programs that you can
download and run on your own computer,
You can also run both programs on any MSU networked computer without downloading and installing them. Look for GenX.exe and for the run.bat file in the Populus folder within the Biology 303 folder at \\hopper\labshare (which you can access using 'Map Network Drive' by right-clicking 'My Computer' on any networked machine). To learn about access to software on the MSU local network, see this link: Using Network Drives to Access Software on the MSU network.
lecture notes and reading assignments: Lecture titles will be
linked to lecture notes. We will post each lecture’s
notes after the lecture.
