All Master's Theses
Daphnia are a genus of freshwater zooplankton that inhabit ponds and lakes. They are commonly used as a model organism because they can reproduce clonally and are considered a foundation species in pond ecosystems. Daphnia melanica that inhabit the subalpine ponds of the Olympic National Park are exposed to high levels of ultraviolet radiation (UVR). UVR causes DNA damage that can be detrimental to the organism if not fixed. One way to avoid these harmful rays is to migrate to protected areas. In my study, I looked at two behaviors in D. melanica: diel vertical migration (DVM), which involves …
