Modification Of Host Behavior And Transmission In The Acanthocephalan Acanthocephalus Dirus: Effects Of Development, Intraspecific Conflict, And Host Sex, Sara R. Teemer
College of Science and Health Theses and Dissertations
Parasites are organisms that live on or in another in order to survive. In some cases, parasites require more than one host to complete their life cycle and rely on a predation event for transmission to the next host. Inside the host, the parasite must access host resources to grow and develop from the non-infective to infective stages. At the infective stage, the parasite is able to survive within the definitive host. Development to this stage has been correlated with changes in antipredatory behaviors, body size and color, and reproduction of intermediate hosts in ways that may increase predation by …
Host-Parasite Relationships Between The Copepod Naobranchia Lizae And Its Host (Striped Mullet, Mugil Cephalus): A Description Of Morphological Development, Sara R. Teemer
DePaul Discoveries
The parasitic copepod, Naobranchia lizae, is often found within the gill arches of the striped mullet, Mugil cephalus, in the Charleston Harbor Estuarine System of South Carolina. The parasite is relatively common, but little is known about its early stages of development. In order to describe the developmental stages and pattern of morphological development, 221 female N. lizae that were collected between February 2002 and May 2003 were used. Using variation in morphological characters (maxilla, trunk), these parasites were assigned to developmental stages (juvenile, subadult, adult). A small number of the males (three ‘dwarf’ males) were also found …
