This video is about the importance of the grassland ecosystem.  It gives an overview of grasslands, discusses photosynthesis, and shows how other life is supported by plants. The Konza Prairie and Shortgrass Steppe, the grasslands shown in this video, are both part of the LTER (long term ecological research) network.

All photos used in the video were taken by me.

We are using RFID technology to link personal videos, photos, and memories together in time. These tagged collages are joined together on personalized postcards that we call Bulacards. The integration of art, science, and music allows us to create and share our personalized impressions of the world. We used a Nokia 6212 to read and display a video about interactions between art and biology from a tagged postcard (Bulacard). This film was submitted to www.ChloroFilms.org for use in education and plant biology.

Time lapse openings of hundreds of flowers are "choreographed" to dance to the traditional Mexican song, La Bamba.

Every single flower and plant in this film was grown by me, in my own garden. I shot all of the original video myself, no stock footage was used. I designed the font used in the titles. This film was my MFA Thesis film for UCLA Film School.

Priming is a widely used technique to enhance the seed potential in relation to the range and uniformity of germination. Priming consists in a controlled imbibition of seeds in order to improve some metabolic events without germination to be completed. In the soil seed bank, seeds are exposed to a variable environment including variations in temperature and water potential. These factors may vary in one single day causing periods of hydration-dehydration that resembles laboratory priming.

My colaborator is my brother, Marco Reyna Llorens.

A basic, but entertaining introduction to Photosynthesis. The glucose molecule is a source of energy, produced by photosynthesis. This introduction covers the Model organism Arabidopsis Thaliana, Chloroplasts, Photosystems 1 and 2, and finally the Calvin Cycle.

How does a tiny seed eventually accumulate the material to make a huge tree? Most MIT and Harvard grads don't know. Here we use marshmallow Peeps to show how CO2 is converted into the substance of massive trees.

The video is based on an experiment of a Plant physiology course (HORT301) for Horticulture and Biology students. It is a student production for the www.ChloroFilms.org competition. It depicts how flower pigments are analyzed using thin layer chromatography (TLC) and spectrophotometry. Investigations that shed light on the chemical and physical behavior of flower pigments are also shown as the isolated pigments are subjected to different pH and the change in spectral behavior (change of color) is monitored. In addition to visualizing pigments on a TLC plate and recording the different molecules that make up each pigment extract from flowers of different colors, we also visualize flower pigments under UV light which allows to detect new separated molecules, which were invisible before. This helps to address the question: what do animals see if they see flowers? Insects have the ability to see different spectral wavelength and thus receive additional information from pigmented flowers.

We developed educational videos to enhance the student’s ability to learn and appreciate plant biology. One of the problems we want to address is the knowledge gap of students from diverse science backgrounds in a Plant Physiology course (HORT301) at Purdue University. We want to ensure not to overwhelm some who have less experience in experimentation while still challenging students who are already familiar with methodology. Our goals are to enable the students to 1) identify basic terminology related to laboratory procedures, 2) to identify single basic steps in laboratory procedures, 3) to carry out basic steps in lab and research procedures and to 4) develop a positive attitude towards the process of scientific ‎discovery. The idea is to translate basic scientific information into language that appeals to the students and engages them in a discourse with the lab material through use of popular culture and visually stimulating instruction. Undeniable, the built-in "cool factor" by using fast cuts, a stimulating musical score and frames within frames creating a high paced flow offers information at a greater rate by employing the stimulating element of audio/visuals that is very common and comprehensible within students. All steps of production of this video involve the students who also perform in this video. The students were actively involved from the storyboarding, preparing the locations, shooting the footage, designing animations to the editing process and finalizing the cut of the material after critical review. Video camera equipment was supplied by Purdue University’s Digital Learning Collaboratory at ITaP (http://dlc.purdue.edu/cs4.cfm) and through an Instructional Innovation grant by the College of Agriculture. Editing of the material and production of musical score has been done together with Diana Nucera (Video artist, Detroit, MI) and Ribo Espino (High school student, Chicago, IL), respectively. More background information on our video productions can be found at http://www.hort.purdue.edu/hort/academics/HortMedia/hortmedia.html.

Since the beginning of agriculture, farmers have developed methods for managing weeds, insect pests and diseases. Due to the significant impact from pests and diseases, on both human and animal health, it is important for those interested in plants to develop a firm understanding of weed science, entomology (study of insects) and plant pathology (study of plant disease), and how to minimize losses caused by these important plant pests. This video will highlight plant diseases and give resources for more information on plant pathology. Also visit the Chlorofilms web site for more videos on plants: www.chlorofilms.org.
