2,4-Dichlorophenoxyacetic Acid Pathway Map

2,4-Dichlorophenoxyacetic Acid Pathway Map

Rating

The University of Minnesota Biocatalysis/Biodegradation Database (UM/BBD) contains "microbial biocatalytic reactions and biodegradation pathways primarily for xenobiotic, chemical compounds." A new microbial enzyme-catalyzed reactions has been posted for 2,4-Dichlorophenoxyacetic Acid. 2,4-dichlorophenoxyacetic acid (2,4-D) is used in cultivated agricultural areas, rangeland and pastures, forests, and homes or gardens, and is "a chlorinated phenoxy compound [that] functions as a systemic herbicide and is used to control many types of broadleaf weeds." The degradation pathway map includes organisms which can initiate the pathway. The pathway map provides detailed information on each hyperlinked step, including graphics, product/substrate reactions, and external links to further information.

77 Degrees South

77 Degrees South

Rating

This resource introduces students to the Dry Valleys of Antarctica, the largest area on the continent that is not covered by ice. Materials include a map and some brief facts about Antarctica and the valleys, such as size, location and physical properties (temperature, precipitation and others), and an online journal in which participants in the Dry Valleys Long-Term Ecological Research (LTER) project discuss what it is like to live and work there. The journal entries include descriptions of some of the organisms that inhabit the extreme environments of the valleys, physical features of the valleys, and the strange mummified bodies of animals such as penguins and seals that have been preserved in the cold, dry climate. There is also a glossary of acronyms used in the project and a set of links to other websites with additional information about the Dry Valleys.

AH-CHOO!: A Case Study on Climate Change and Allergies

Rating

As the carbon dioxide concentration of our atmosphere increases and our climate warms, the hay fever season seems to be getting longer and more severe. In this case study, students assume the a role of a public relations specialist contracted to communicate the link between climate change and pollen allergies. The activity focuses on the importance of scientific skills to careers outside science, and is most suitable for a lower-level introductory biology, human health, or environmental science course.

ARKive: Images of Life on Earth

ARKive: Images of Life on Earth

Rating

ARKive is a collection of photographs, videos, and fact-files illustrating thousands of species of animals, with emphasis on the International Union for Conservation of Nature and Natural Resources (IUCN) Red List of endangered species, and on species found in Britain. For each animal there are approximately 10 minutes of video footage, 6-10 still photos, and sound recordings (where appropriate), creating a complete profile of the species' characteristic behavior and appearance. The images are accompanied by a page of facts, including taxonomy, a physical description, conservation status, geographic range, habitat, and other information. There are also links to other animals with related taxonomic families, habitats, or conservation status.
