Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

Wolbachia is a genus of bacteria that infect cells of invertebrates. Surveys have found that up to a fifth of insect species have at least some individuals infected with Wolbachia. Pathogen or parasite? This endosymbiont (a symbiont that lives inside its host) bacteria can have many effects on its host, including killing offspring and changing the sex of offspring. Ary Hoffmann from the University of Melbourne in Australia, Michael Turelli from the University of California at Davis, and their associates have been studying Wolbachia infections in populations of Drosophila simulans from California. From the initial infection around 1980, Wolbachia infection spread northward across the state during the 1980s and 1990s. The most striking manifestation of infection in this fly species is cytoplasmic incompatibility: offspring produced in crosses where males are infected and the females are uninfected tend to die early in development. In crosses between infected males and infected females,…

Many fish purchased and consumed by humans are bred and raised in fish farms. The fish on a farm can be infected by parasites called sea lice, which are small crustaceans that feed on a fish's blood and skin, which may injure or even kill the fish. Jansen and colleagues (2012) analyzed sea lice infections on trout and salmon farms. Fish farms provided data on the numbers of sea lice found on their captive fish. The scientists compared the number of sea lice with the "local farmed fish biomass density," which is a measure of population density that accounts for both the number and biomass (or size) of fish on a farm. Other research has also found a relationship between sea lice infestation and mortality. From this figure and information, how does density of fish on a farm affect the number of sea lice per fish? What type of factor is regulating the size of farmed fish populations and population growth? 100 200 300 400 Local farmed fish biomass density (metric tons) 3. 2. Sea lice counts

DOTa species The pesticide DDT was widely used in the 1940s as a method of insect control. In the late 1950s the first DDT-resistant mosquitoes were discovered, and eventually DDT-resistant mosquitoes were found globally. When DDT is used now, the development of DDT resistance in mosquito populations occurs in months rather than years.Which of the following best explains the observations concerning DDT resistance in mosquitoes? * The proportion of DDT-resistant mosquitoes in a population remains constant due to the metabolic costs of DDT utilization DDT is a chemical signal that delays normal reproductive cycles in many mosquito populations. Natural selection favors DDT-resistant mosquitoes that are already present in a population when DDT exposure occurs. Competition for limited resources causes mosquitoes to migrate to geographical areas that have richer supplies of DDT. A population of 1,492 finches is introduced to a rainforest. Over the next year, the finches showa death rate of…
