PASSeL2: Recent Episodes
None
Introduces the mechanisms by which insects can achieve resistance to pesticides. Covers behavioral, physiological (reduced penetration, metabolic detoxification, and target site insensitivity), plus other insecticide targets. *This video contains no audio.
RGB and Multispectral sensor attachment to a drone. The video also shows what the tablet looks like while the drone is collecting data.
How to interpret "Inheritance of an ALS-Cross-Resistant Common Cocklebur (Xanthium strumarium) Biotype" by G. Anthony Ohmes and J. Andy Kendig.
This video is about selection pressure, selecting for resistance genes, and mode of action in plants.
This video describes how gene flow and genetic drift impact allele frequencies for some pesticide resistant populations.
This video details the impact of mutations and selection on allele frequencies for various pesticide resistant populations.
This video describes examples of pests that utilize alternative methods of reproduction.
A summary of two types of genetic mutation (frameshift and point mutation) and how the mutation can impact trait expression. Mutations are learned through the lens of pesticide resistance.
Trait expression is the process by which genes becomes proteins, and it occurs in two parts: transcription and translation. This video describes the process of translation.
Trait expression is the process by which genes becomes proteins, and it occurs in two parts: transcription and translation. This video describes the process of transcription.
You'll learn the genetic basis for resistance genetics through the example of herbicide resistant Palmer amaranth. This video describes genes, trait expression, and traits.
This video is about selection pressure, selecting for resistance genes, and mode of action in plants.

This short video will help you picture the connections between genes, trait expression and traits
In this video you will be learning about the different major types of mutations and how they are one of the origins of pesticide resistance.
A brief description for what Standard Deviation and Standard Error are and what they mean in the context of research and how it is used.
Learn about Dr. Wortman's work with Biomultch and how it is used and the potential benefits it may have for vegetable crop production.
Learn about Standard Deviation and Standard Error and why they are important in research. Then we will go through how to calculate each.
Introductory video on how to read/write scientific peer reviewed articles. Detailing the structure of these professional writings.
Developing excel skills by demonstrating how to create a line graph and how to improve/edit the graph to fit your needs and goals.
Use data management techniques to create mean data and use it assemble into a line graph to compare buffalo grass cultivars.
Learn how data collection for Buffalo Grass breeding trials work and analyze the data collects. Develop data sorting skills as well as an understanding of when to reject data that does not belong due to an error or abiotic and biotic stress factors.
Learn to make further calculations with the data given in the Buffalo Grass part 2 data and clean up the data to be more presentable. Learn the skills that are important to creating an effective line graph.
Building off other videos where you learn to collect data using a scale. We will used the scaled data to create a bar graph that helps the viewer visualize the data in a better way. Watch step by step as the author Kristina Alas demonstrates how to create a bar graph that is descriptive and customizable.
Provides an understanding of various insecticide resistance mechanisms. This video has no audio
An overview of how genes affect an organism's traits, and how those genes are passed from one generation to the next. Also explains how scientists map locations of genes on chromosomes.
This video covers how to characterize developmental stages of tillers and quantify them.
This animation compares the timeline for genetic engineering versus traditional plant breeding. It also compares the regulatory processes of each.
Discusses the relationship between the amount of nitrogen applied and how it affects grain yield and protein concentration in a grain crop.
Discusses the relationship between the amount of nitrogen applied and how it affects the protein fraction, lysine concentration, and kernel hardness of a grain crop.
Dehydration is the removal of water from rock or mineral structures. A good example of dehydration is the removal of water from limonite, resulting in the formation of hematite.
Esta animación describe como se mueve el agua a través de las plantas y como este movimiento es afectado por diversos factores.
This animation details how water moves through plants and how various factors affect this movement.
This animation describes how herbicides are taken up by leaves and illustrates how physico-chemical characteristics alter their movement across cuticles. Passive and active mechanisms of herbicide absorption across plant membranes into cells are shown as well.
Learn about the life cycle of perennials and how defoliation at different times of the season and different heights affects their growth and carbohydrate reserve levels.
This video explains how strip cropping can reduce wind erosive energy and traps moving particles
This video explains the beneficial effects of soil surface cover to control and reduce wind erosion.
This video clip explains how wind erosion can be reduced by roughening the soil surface and forming soil aggregates. This method of erosion control can be used when vegetation is sparse and/or the cropping system does not allow for vegetative cover.
This video explains the beneficial effects of vegetative cover in reducing wind erosive energy and trapping moving particles.
This video clip explains how barriers alter the effect of the wind force on the soil surface. The video discusses the different types of barriers and their advantages and disadvantages.
Factors and processes of wind erosion are explained in this video clip. The clip explains how wind velocity or speed affects wind erosive energy. The video also explains how the nature of the soil surface affects erosive wind energy.
