6. Emerging and Re-emerging Diseases Chapter 8 Disease is not constant • Emerging Diseases – are recently “discovered” diseases, or diseases that have become increasingly important. • Some are old diseases just discovered – like Hepatitis C • Some are truly new like HIV • Many are taking advantage of some niche – like air conditioners in large buildings – Legionella pneumophila • Diseases moving to new parts of the world – West Nile Virus • Re-emerging Diseases – are diseases that became less

Interestingly, there is a group of living plants - the whisk ferns - which resembles Rhynia. Psilotum nudum which grows in moist, shady habitats in the Caribbean is such a plant. At one time, Psilotum was thought to be a surviving relative of Rhynia. It is, however, more generally thought to be a Fern Ally, related to the Ferns, with loss of features such as leaves and roots.

Biological classification Biological classification is the arrangement of organisms into categories that express their PHYLOGENY, or line of descent, based on information such as structure, development, biochemical or physiological functions, and evolutionary history of organisms. The purpose of such a classification is to provide a clear and practical way to organize and communicate information about organisms. Classification can show relationships between different ancient and modern groups, indicate

A microscope (from the Ancient Greek "small" "to look" or "see") is an instrument used to see objects that are too small for the naked eye. The science of investigating small objects using such an instrument is calledmicroscopy. Microscopic means invisible to the eye unless aided by a microscope. There are many types of microscopes. The most common (and the first to be invented) is the optical microscope, which uses light to image the sample. Other major types of microscopes are theelectron microscope (both

Marine Mycology: An Overview of Pathogens, and Secondary Metabolites Introduction and History The golden age of marine mycology occurred from 1960-1990 with the research and discovery of most of the roughly 500 species of obligate marine fungi. Much of said research was conducted from 1980-2000; this 30 year period saw the report of nearly half of the marine fungal species currently known (Jones et al. 2009; Jones, 2011). That being said, marine fungi are vastly understudied and under rated in

V. Racaniello page 1 Viral Pathogenesis This lecture will define and discuss the basic principles of viral pathogenesis, the entire process by which viruses cause disease. Viral disease is a sum of the effects on the host of virus replication and of the immune response. Interest in viral pathogenesis stems from the desire to treat or eliminate viral diseases that affect humans. This goal is achieved in part by identifying the viral and host genes that influence the production of disease. Progress

James Shin Per 7b/8 Ecology Take Home Test 1) In the given info, there were two groups, an experimental and control group of flowers and sagebrush in a desert landscape that were identical except that the experimental group had a fence enclosed around it. Also, there was a predation relationship between the wildflowers and the kangaroo rats because the kangaroo rats eat wildflowers. Assuming that the fence was limiting the space of the experimental plot, competitive exclusion caused the extinction
