Extreme conditions on <i>Daphnia dentifera<\/i>, also known as water fleas, and it&#8217;s fungal pathogen (<i>Metschnikowia bicuspidata<\/i>), can alter disease dynamics and population dynamics. This study was designed to answer the question, &#8220;Does the influence of temperature variability have an effect on the host-parasite relationships within <i>Daphnia<\/i>.&#8221; \u009d Also we wanted to answer the question &#8221;Does a change in pH have an effect on the host-parasite relationships or an effect on the population?&#8221; We show that we exposed half the population to the pathogen. A temperature of 20C was used as a control and 12C and 28C were the two extreme temperatures, with time variations of either 0,1,2, or 4 hours. This study is ongoing and data are still being collected. To alter the pH, we added a HCL solution to the populations and exposed half the populations to the pathogen to answer the question &#8221;Does pH have an effect on infection and spores within Daphnia?&#8221; \u009d After examining the data, we didn&#8217;t find any useful data to answer our big question.<\/p>\n<p><code><iframe src=\"\/\/docs.google.com\/viewer?url=http%3A%2F%2Freu.ecology.uga.edu%2Fwp-content%2Fuploads%2F2014%2F10%2F2014Trianna.pdf&hl=en_US&embedded=true\" class=\"gde-frame\" style=\"width:100%; height:500px; border: none;\" scrolling=\"no\"><\/iframe>\n<p class=\"gde-text\"><a href=\"http:\/\/reu.ecology.uga.edu\/wp-content\/uploads\/2014\/10\/2014Trianna.pdf\" class=\"gde-link\">Download (PDF, 1.1MB)<\/a><\/p><\/code><\/p>\n","protected":false},"excerpt":{"rendered":"<p>For this project, based in the lab of Dr. John Drake, Trianna Humphrey worked with Tad Dallas to study the effect of changing environmental conditions on a host-parasite relationship.
