Influenza is one of the most common diseases‚ causing millions of severe illnesses and huge number of deaths per years. Recent concerns were focused on H5N1 avian influenza virus that was first isolated in a domestic goose in China in 1997 due to its high case of death rate (Lucchetti‚ Roy & Martchvae‚ 2008). Influenza viruses are single-stranded RNA viruses of which 3 types

Population Ecology Ingrid Rhody BIO/101 March 7‚ 213 Kirsten Hagen MS Population Ecology Population ecology is the affect of a populations density and extension. When a group of single species occupy the same general area it is known as a population. This group of species will rely on resources and the same environmental atmosphere. The number of species within a group that occupy the same area or habitat is known as population density. Some ecologists use different types of techniques

Stream Ecology Lab Report Jesse Paner Bio 192 Professor LaMontagne Introduction Ecology is the scientific study‚ which focuses on the interactions between organisms and their environments as well as interactions with other organisms. Stream ecology is a subset of ecology that observes the interactions between the organisms found within the stream and their interactions with the stream itself. A contributing factor to stream ecology is leaf degradation. Leaves that fall into a stream create a significant
