North American Invasive Plant Ecology and Management Short Course Steve Young
Welcome to the North American Invasive Plant Ecology and Management Short Course (NAIPSC) Online Community! The NAIPSC Online Community houses information about the NAIPSC Field Course, instructors, resources, and future opportunities to increase your knowledge of invasive plants.
NEW! 2012-2013 NAIPSC Webinar Series!
The NAIPSC is hosting a series of webinars throughout 2012 and 2013. These webinars will be provided free to past NAIPSC participants, and for a fee to all other potential attendees. Your webinar series fee may apply toward enrollment in the 2013 offering of the NAIPSC. For more information about the webinar series and the course, go to http://ipscourse.unl.edu or contact Steve Young at email@example.com.
You may attend webinars and view all archived webinars in the series by joining the NAIPSC Online Community. To the left of this page, you will see a link to the NAIPSC Online Community under "Related Communities." Approval of your request to join will be subject to past course participation or payment of the webinar series registration fee.

Translation A detailed depiction of translation, the second stage of protein synthesis. This is the third in a series of three animations on protein synthesis. To begin at the beginning, go to Protein Synthesis - A general overview.
Making a Recombinant Plasmid This animation shows how a plasmid responsible for encoding a gene can be cut. The plasmid can be altered with the addition of linear DNA to form a recombinant plasmid to encode a new gene of interest.
This is the first of four animations detailing the gene cloning process. The other three animations are Bacteria Transformation, Making a Library, and Screening a DNA Library.
Making a Gene Library This animation shows how to make a colony of new DNA in order to locate a specific gene of interest. This is the third of four animations detailing the gene cloning process. To begin at the beginning, choose Making a Recombinant Plasmid. (The animation prior to this one is Bacteria Transformation. The animation just after this one is Screening a DNA Library.)
Chi-Square Test for Goodness of Fit in a Plant Breeding Example
In plant breeding and genetics research, plant breeders establish a hypothesis to explain how they think a particular trait is inherited, such as if it is due to one gene with complete dominance, an interaction of more than one gene, or quantitative inheritance, with many genes contributing, etc. Next the breeder sets up crosses and observes the resulting progeny to test that inheritance hypothesis. However, when the data is collected, oftentimes the plant breeder discovers the number of plants observed in each class is not exactly what was expected from the hypothesis. The question then is how do plant breeders determine if the data is close enough to what they expected to determine the hypothesis is supported or not? Following a tomato disease resistance example in this lesson, you will learn a simple statistical test that breeders can use to conclude if the experimental data supports their hypothesis of single gene, completely dominant inheritance.
This lesson is written for undergraduate and graduate students studying plant breeding, as well as agriculture professionals unfamiliar with the use of the chi-square analysis.
