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...

Isozymic and cytological studies on populations of the introduced bee species, Megachile (Eutricharaea) rotundata and M. (Eutricharaea) apicalis

Creator:: Chen, Xiaoshe
Abstract:: Thirteen New World populations of Megachile rotundata and M. apicalis and two Old World populations of M. rotundata were analyzed at 23 enzyme loci using cellulose acetate electrophoresis. Conventional and G- or C-banded karyotypes were also examined in these populations. The principal findings are (1) No differences were found in...

Soil respiration, carbon and nitrogen leaching, and nitrogen availability in response to harvest intensity and competing vegetation control in Douglas-fir (Pseudotsuga menziesii) forests of the Pacific Northwest

Creator:: Slesak, Robert A.
Abstract:: Management practices following forest harvest can affect long-term soil productivity through alteration of soil carbon (C) and nitrogen (N) pools, but processes contributing to change are poorly understood. I assessed effects of three levels of logging-debris retention in combination with initial or annual applications of competing vegetation control (CVC) following...

Some potential mechanisms for finely-tuned regulation of phospholipase C-β isozymes : studies of dimerization and phosphatidylinositol 3,4,5-trisphosphate activation

Creator:: Zhang, Yong
Abstract:: Phospholipase C-β (PLC-β) isozymes are key effectors in G protein-coupled signaling pathways. Prior research suggested that some isoforms of PLC-β may exist and function as dimers, but little is known about dimerization of PLC-β. Data from coimmunoprecipitation assays of differentially-tagged PLC-β constructs and sizeexclusion chromatography of native PLC-β support homodimerization...

Diversity of bacterioplankton and plastid SSU rRNA genes from the eastern and western continental shelves of the United States

Creator:: Rappé, Michael Stephen
Abstract:: The phylogenetic diversity of two continental shelf picoplankton communities was examined by analyzing SSU (16S) ribosomal RNA (rRNA) genes amplified from environmental DNA with bacterial-specific primers and the polymerase chain reaction (PCR). Picoplankton populations collected from the pycnocline (10 m) over the eastern continental shelf of the United States near...

Outliers: The Unusual Characteristics of Marine Carbon-Oxidizing Bacterial Cells Adapted to Oligotrophic Conditions

Creator:: Noell, Stephen E.
Abstract:: Oligotrophic bacteria are adapted to low nutrient concentrations. As most of the ocean is oligotrophic (low in nutrients), oligotrophic bacteria thrive in the ocean and make up the majority of planktonic cells. Because of this, oligotrophs are crucial to oceanic nutrient cycles. However, marine oligotrophic bacteria are dwarfed by their...

Computational Elucidation of the Regulatory SNPs in the Non-Coding Regions of the Human Genome

Creator:: Yao, Yao
Abstract:: We describe a series of novel computational models, CERENKOV (Computational Elucidation of the REgulatory NonKOding Variome) and its successors CERENKOV2, CERENKOV3, and Convolutional CERENKOV3, for discriminating regulatory single nucleotide polymorphisms (rSNPs) from non-regulatory SNPs within non-coding genetic loci. The CERENKOV models are designed for recognizing rSNPs in the context of...

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...
