Ecology and conservation biology contain numerous examples of populations growing without bounds or shrinking towards extinction. For these populations, the change in the number of individuals generally follows an exponential curve. On the other hand, limited resources may keep population numbers in check and help maintain the population at the environment's carrying capacity. These density-dependent constraints on population growth can be described by the logistic growth equation. The…

This collection of about 50 modules were developed to accompany general biology courses and allow instructors to add some quantitative examples in many of the topics in a standard GB sequence. The modules mostly use high-scholl level math and have a uniform structure of :  introduction, importance, questions, methods, variables, analysis and/or data, interpretation, conclusions and additional questions for students to address.

From source site: “This website is designed to provide a variety of information about the text Mathematics for the Life Sciences. It provides some material that supplements the presentations in the text, and will be the primary method used by the authors to pass on new material related to the text to readers. We have endeavored to compose the text so that it is self-contained and hope that readers at various levels of mathematical preparation find it to be accessible. It is…

In this module we introduce the important notion of the replacement number, which generalizes the basic reproductive number R0. We investigate how this number behaves near the start of an outbreak in models based on the uniform mixing assumption and in models that assume a contact network that is a random k-regular graph with small k. We also illustrate a method for estimating the value of R0 from epidemiological data.

Level: Advanced undergraduate and graduate students of…

In this module we introduce the so-called friendship paradox and illustrate how it affects disease transmission on networks that exhibit this phenomenon.

You also need to download the input file degreesFP.txt that will be used in this module.

Level: Advanced undergraduate and graduate students of mathematics.

Requires: Module The replacement number.

Wood density data used in this activity are derived from: Zanne AE, Lopez-Gonzalez G, Coomes DA, Ilic J, Jansen S, Lewis SL, Miller RB, Swenson NG, Wiemann MC, Chave J (2009) Data from: Towards a worldwide wood economics spectrum. Dryad Digital Repository. doi:10.5061/dryad.234

In this data driven curriculum module students will use an authentic data set from Dryad Digital Repository to explore whether evolutionary tradeoffs actually occur in plants and whether evolution has led to tissue…

These are the materials for Math 214 offered at Rhodes College. The course description is:  "In this course students will learn how to use discrete mathematical models to analyze problems arising in the biological sciences, without using calculus. The types of models used will include discrete difference equations, matrix models, and agent-based models. Some of the biological applications explored in this course include modeling the population sizes of various species over time, describing..."

The Nature of Things - Invasion of the Brain Snatchers

This is a link to and episode of the The Nature of Things featuring parasites that manipulate their hosts. This is a great resource for undergraduate parasitology AND intro bio courses. I have used it for both. I show the entire episode in my Animal Parasitology course along with questions for the students to answer in groups at different time intervals throughout. Then they submit their answers as a group. In General Biology I show a 10 minute clip when I introduce parasitism as a life history strategy in the Community Ecology Chapter.

PARA-SITE: An interactive multimedia electronic resource dedicated to parasitology

Website hosted by The University of Queensland developed by the Australian Society of Parasitology, Inc. 

This website has useful background information on parasitology and individual parasites, their life cycles, host use, mode of transmission and clinical consequences. 

This would be a great resource for a medical parasitology course, or medical part of a general parasitology survey course. I could even see the descriptive information being useful in a general bio course for a definition of parasitism. The website also includes a nice section on fields of study within parasitology showing where it can overlap with courses in other disciplines.

Centers for Disease Control and Prevention Parasitology Training Materials

This website includes images associated with parasite infection events submitted to the CDC. The images represent what would be available for diagnosis, but the website is organized by date of report rather than by parasite taxonomy.

This homepage leads to other links for medically important parasitic infections as well as information on diagnostic  procedures. Under the case studies page you can find images and associated information with actual patient information from parasite infection reports. These have been useful in my teaching as mini-case studies on diagnosis.

"Towards a worldwide wood economics spectrum" - Paper with the published dataset

Abstract:

Wood performs several essential functions in plants, including mechanically supporting aboveground tissue, storing water and other resources, and transporting sap. Woody tissues are likely to face physiological, structural and defensive trade-offs. How a plant optimizes among these competing functions can have major ecological implications, which have been under-appreciated by ecologists compared to the focus they have given to leaf function. To draw together our current understanding of wood function, we identify and collate data on the major wood functional traits, including the largest wood density database to date (8412 taxa), mechanical strength measures and anatomical features, as well as clade-specific features such as secondary chemistry. We then show how wood traits are related to one another, highlighting functional trade-offs, and to ecological and demographic plant features (growth form, growth rate, latitude, ecological setting). We suggest that, similar to the manifold that tree species leaf traits cluster around the ‘leaf economics spectrum’, a similar ‘wood economics spectrum’ may be defined. We then discuss the biogeography, evolution and biogeochemistry of the spectrum, and conclude by pointing out the major gaps in our current knowledge of wood functional traits.
