Soil Bacteria and Actinomycetes What They Are and A Few Interesting Facts Bacteria are common throughout the soil, but tend to be most abundant in or adjacent to plant roots, an important food source. Actinomycetes are a broad group of bacteria that form thread-like filaments in the soil. They are responsible for the distinctive scent of freshly exposed, moist soil. Why They Are Important Bacteria are important in the carbon cycle. They contribute carbon to the system by fixation (photosynthesis) and decomposition. Bacteria are important decomposers in grassland environments. Actinomycetes are particularly effective at breaking down tough substances like cellulose (which makes up the cell walls of plants) and chitin (which makes up the cell walls of fungi) even under harsh conditions, such as high soil pH. Some management activities, particularly those that change nutrient levels in the soil, can shift the dominance of decomposers from bacterial to fungal. When one group becomes dominant where it shouldn't be, there is also a shift in the rest of the system. The shift from bacterial to fungal dominance, for instance, can enhance the conditions favoring weed invasions on rangelands. Bacteria are particularly important in nitrogen cycling. Free-living bacteria fix atmospheric nitrogen, adding it to the soil nitrogen pool. Other nitrogen-fixing bacteria form associations with the roots of leguminous plants such as lupine, clover, alfalfa, and milkvetches. Actinomycetes form associations with some non-leguminous plants (important species are bitterbrush, mountain mahogany, cliffrose, and ceanothus) and fix nitrogen, which is then available to both the host and other plants in the near vicinity. Some soil nitrogen is unusable by plants until bacteria convert it to forms that can be easily assimilated.

Raven/Johnson: Chapter 34 Feedback Help Center Biology Laboratory Manual, 6/e Darrell S. Vodopich, Baylor University Randy Moore, University of MinnesotaMinneapolis Bacteria Bacteria simply dominate the Earth. Scientists often refer to the Age of the Dinosaurs or the Age of Mammals or discuss the immense diversity and abundance of insects. But, bacteria are the oldest, most diverse, most abundant organisms on Earth. They always have been and, most likely, always will be. Bacteria are able to live in a wide variety of environments. They have been found in the intestines of vertebrates, around volcanic vents at the bottom of the ocean, and in swamps where there is no oxygen. Though some bacteria are rather fragile and will be killed by soap and water, there are some species that are resistant to extreme temperatures, most antibiotics, and perhaps even the vacuum of space.

Department ofBiological Sciences Kent State University Dr. Laura G. Leff My research focuses on microbial ecology of aquatic ecosystems withemphasis on bacterial ecology of streams. Present projects in my laboratoryinclude: comparison of bacterial communities among different streams, examinationof the effects of microgravity on biofilms, evaluation of methods for identification of aquatic bacteria, effects of pollution on bacterial biodiversity, anduse of molecular techniques in aquatic ecology. One of the ultimate goalsof my research is to integrate different fields of biology (i.e., ecology,microbiology, molecular biology) to provide insight into the function andstructure of aquatic ecosystems. The intent and goals of my research isdescribed in: Leff, L. G. 1994. Stream bacterial ecology:a neglected field? American Society for Microbiology News, 60:135-138. I also have conducted research in freshwater environments on organic matter processing, invertebrate population ecology (molluscs), and vertebratefeeding behavior.

Bad Biology Atrocities committed in the name of biology Having read the fabulous Bad Science pages I decided to rise to the author's challenge of dismissing appaling biology wherever I can rout it out. There's a lot of bad biology out there, hopefully this site isn't too riddled with it, besides my thinking memes are an elegant idea in the absence of decent evidence :) At least I put this in the rants section rather than the science bit. Anyway, here is my top ten bits of bull botany and moronic mycology, in order of how perniciously awful they are. I have missed out creationism and medical fraud , which would otherwise top my list, on the basis that they have entire essays devoted to them elsewhere. 10. Not very sapient homos OK, so it's more poor spelling than really bad biology, but it's still inordinately annoying to read about homo ' Sapiens ' and Cannabis Sativa. It's simple. It's a CAPITAL letter on the first word, a small letter on the second, and all of it in italics . If you're a horticulturalist, it may get slightly more difficult, but is it too much for the rest of you to remember just three things?

Students also learn simple methods to create dark field lighting and colored-field lighting as well as polarized light microscopy that will greatly increase their microscopy skills and viewing. The program provides clear examples and beautiful photomicroscopy that will inspire students to build and improve their microscopy skills The Biology of Viruses introduces these strange parasitic entitieslittle more than packages of genetic information that subvert cells into producing more viruses.
