Biophysical factors driving the distribution and abundance of redband/steelhead trout (Oncorhynchus mykiss gairdneri) in the South Fork John Day River Basin, Oregon, USA

Creator:: Madriñán, Luis Francisco
Abstract:: The overall goal of this study was to identify multiple scales of habitat use and habitat electivity by redband/steelhead trout and define the limiting factors affecting the distribution patterns of this species during summer flows. The main objective in chapter 2 was to identify the most important habitat associations that...

Histopathological assessment of liver and gonad pathology in continental slope fish from the northeast Atlantic Ocean

Creator:: Feist, S. W., Stentiford, G. D., Kent, M. L., Santos, A. Ribeiro, and Lorance, P.
Abstract:: The deep-sea environment is a sink for a wide variety of contaminants including heavy metals and organic compounds of anthropogenic origin. Life history traits of many deep-water fish species including longevity and high trophic position may predispose them to contaminant exposure and subsequent induction of pathological changes, including tumour formation....

Aspects of the foraging ecology of humpback whales (Megaptera novaeangliae) in Frederick Sound and Stephens Passage, Southeast Alaska

Creator:: Szabo, Andrew R.
Abstract:: The North Pacific humpback whale (Megaptera novaeangliae) population has been increasing at an average annual rate of ~6% since the early 1990s. In northern Southeast Alaska alone, there are now more whales than estimated for the entire North Pacific several decades ago. An understanding of how this growing population is...

Investigation of Nematocyst Discharge in Parasitic Cnidarians (Myxozoa)

Creator:: Americus, Benjamin E.
Abstract:: Myxozoans are an enigmatic group of obligately parasitic, microscopic cnidarians. They diverged from their free-living relatives over 600 million years ago and have highly reduced genomes. However, they have retained nematocyst stinging cells which characterize the phylum Cnidaria. Free-living cnidarians utilize this cellular weaponry for defense and predation whereas the...

Development of Computational, Visualization, and Molecular Tools for Fungal and Oomycete Community Ecology

Creator:: Foster, Zachary Stephen Longiaru
Abstract:: Oomycetes are an important group of organisms with a variety of ecological roles similar to fungi. Although many are well-studied plant pathogens known for their devastating effects on agricultural systems, most are little-studied saprobes and parasites of plants and animals in nearly every ecosystem on earth. The advent of affordable...

How Do Parasites Infect Salmon? Comparative Transcriptomics Reveal Myxozoan Adaptations for Parasitism

Creator:: Americus, Benjamin
Abstract:: The phylum Cnidaria contains three main branches: Anthozoa (corals, sea anemones) Medusozoa (jellyfish, hydra), and Endocnidozoa. This latter branch is characterized by parasitism and contains the microscopic fish-parasites Myxozoa. Myxozoa are highly simplified, consisting of only a few cell types, however they have retained the nematocyst stinging cells and complex...

The introduction of myxozoan parasites through the release of feeder goldfish (Carassius auratus)

Creator:: Karandashova, Sophia
Abstract:: Myxozoa have been found worldwide; these parasites infect a wide variety of hosts, but have been found most often in fish. Carassius auratus (goldfish), a popular aquarium fish and a widespread invasive species, have been identified as an intermediate host for several myxozoan species. Some myxozoan parasites are pathogenic and...

A comparative study of the isozymic proteins and the effect of metachemogenesis in the tissues of Periplaneta americana (L.)

Creator:: Beckendorf, Gerald Walter
Abstract:: An attempt was made to demonstrate isozymic forms of esterase, MDH, LDH and GPDH and the variation in enzyme pattern with increasing age in the thoracic muscle, appendage muscle and hemolymph of the American cockroach, Periplaneta americana. Sampled specimens of both sexes were aged one through seven days, two weeks...
