Background: Through next-generation sequencing, the amount of sequence data potentially available for phylogenetic analyses has increased exponentially in recent years. Simultaneously, the risk of incorporating ‘noisy’ data with misleading phylogenetic signal has also increased, and may disproportionately influence the topology of weakly supported nodes and lineages featuring rapid radiations and/or...
The effect of salmon blood plasma (SPP) on the gelation of Pacific whiting surimi under different ohmic heating conditions was investigated. SPP was found to significantly increase gel strength in gels heated ohmically to and held at 60° for 30 min followed by heating ohmically to 90°C. SPP at a...
The effect of salmon plasma (SP) from Chinook salmon on proteolytic inhibition was investigated. SP was found to inhibit both cysteine and serine proteases as well as protease extracted from Pacific whiting muscle. SP was found to contain a 55 kDa cysteine protease inhibitor through SDS-PAGE inhibitor staining. Freeze dried...
Organellar DNA sequences are widely used in evolutionary and population genetic studies, however, the conservative nature of chloroplast gene and genome evolution often limits phylogenetic resolution and statistical power. To gain maximal access to the historical record contained within chloroplast genomes, we have adapted multiplex sequencing-by-synthesis (MSBS) to simultaneously sequence...
Premise of the Study: Hybrid zones provide "natural laboratories" for understanding the processes of selection, reinforcement, and speciation. We sought to gain insight into the degree of introgression and the extent of ecological-phenotypic intermediacy in the natural hybrid strawberry, Fragaria x ananassa subsp. cuneifolia.
Methods: We used whole-plastome sequencing to...
Atmospheric and surface ocean temperatures in the Antarctic Peninsula region have increased by a few degrees Celsius over the last few decades, and they are the most rapid changes recorded in the Southern Hemisphere during this time period (Cook et al., 2005; Meredith and King, 2005). Associated with this ongoing...
Large population sizes and global distributions generally associate with high mitochondrial DNA control region (CR) diversity. The sperm whale (Physeter macrocephalus) is an exception, showing low CR diversity relative to other cetaceans; however, diversity levels throughout the remainder of the sperm whale mitogenome are unknown. We sequenced 20 mitogenomes from...
• Premise of the study: The dramatic advances offered by modern DNA sequencers continue to redefine the limits of what can be accomplished in comparative plant biology. Even with recent achievements, however, plant genomes present obstacles that can make it difficult to execute large-scale population and phylogenetic studies on next-generation...
The three-dimensional (3D) double-ridge internal tide interference in the Luzon Strait in the South China
Sea is examined by comparing 3D and two-dimensional (2D) realistic simulations. Both the 3D simulations
and observations indicate the presence of 3D first-mode (semi)diurnal standing waves in the 3.6-km-deep
trench in the strait. As in...
We examined terrestrial amphibians in managed headwater forest stands in western Oregon from 1998 to 2009. We assessed: (1) temporal and spatial patterns of species capture rates, and movement patterns with distance from streams and forest management treatments of alternative riparian buffer widths and upland thinning; (2) species survival and...
