Agent-Based Modeling of an Activated Sludge Process in a Batch Reactor

Authors: Pereda, M., & Zamarreno, J. M. 

About: The aim of this work is to study the feasibility of using agent-based modeling to study the activated sludge process.  A model in MetLogo has been proposed, and experiments have been developed comparing the model behavior with a classical modeling approximation for this process, the Monod model.

R for Biologists

Author: Marco Martinez

This material is intended as an introductory guide to data analysis with the R system, to assist in statistical computing training for life science researchers.  It was produced as companion material for a seminar (R Tutorial for Life Sciences) given at The University of Tennessee in the spring of 2009, sponsored by the National Institute for Mathematical and Biological Synthesis (NIMBioS).

The principal aim is to provide a step-by-step guide on the use of R to carry out statistical analysis and techniques widely used in the life sciences.  In each section, there is a detailed explanation of a command in R, followed by a biological example with all the instructions (in red) needed to run the test and with the corresponding output in R (in blue).  There is assumed previous knowledge in statistics and experimental design, essentially corresponding to a basic undergraduate introductory statistic course.

YAY PROTISTS!

This is a tool that is currently being developed by the working group. In this activity students will be given several interesting protists to research.  Then based on morphological characteristics students will create a hypothesis tree.  Then, students will be given a tree of their organisms based on genetic data.  They will then use Mesquite to map characters onto the tree they are given.

Mesquite

From the developers, "Mesquite is modular, extendible software for evolutionary biology, designed to help biologists organize and analyze comparative data about organisms." Students can use Mesquite to build trees, plot characters onto trees, and explore ancestral state reconstructions.

Mesquite can be run directly on the Hub here, or downloaded from mesquiteproject.org.

Quick bites and quirky adaptations

Interesting news article about convergent evolution of trap jaws in ants. Includes slow motion videos of the ants using these jaws to propel themselves through the air as a defense mechanism.

The evolution of flight in birds

This module examines evidence from the fossil record, behavior, biomechanics and cladistic analysis to interpret the sequence of events that led to flight in the dinosaur lineage. The module concentrates on the process of science - how we know what we know.

Lizard Evolution Virtual Lab

The virtual lab includes four modules that investigate different concepts in evolutionary biology, including adaptation, convergent evolution, phylogenetic analysis, reproductive isolation, and speciation. Each module involves data collection, calculations, analysis and answering questions.

As the Worm Turns - Case Study

At what point in evolutionary development does a group of individuals become two distinct species? This case addresses that fundamental question by asking students to decide whether apple maggot flies are distinct as a species from hawthorn maggot flies. In making their decision, students examine the different models of speciation and consider the primary forces that effect evolutionary change. Developed for an advanced undergraduate course in evolutionary biology, it would be appropriate for any biology course in which students are taught about the models of speciation. It could also be used in a general ecology course in which students consider the distribution and use of resources leading to niche specialization or in a genetics course if restrictions in gene flow are taught in the context of speciation.

Introduction to extinctions and extinction bias

Students will be introduced to different factors that might affect extinction risk and will work with data on artiodactyls (even-toed, hoofed mammals, such as cows, sheep, deer, antelope, and giraffes) to investigate some of these hypotheses.

NetLogo - Bug Hunt

This is a natural/artificial selection model that shows the result of two competing forces on natural selection of the speed of prey. Which force dominates depends on the behavior of predators.

Evo-Ed Cases

A complete understanding of evolution requires knowledge that spans many biological sub-disciplines. However, students are often taught evolution in the context of ecological systems and isolated from genetic and cellular ones. To address this issue, we have developed case studies that track the evolution of traits from their origination in DNA mutation, to the production of different proteins, to the fixation of alternate macroscopic phenotypes in reproductively isolated populations.
