Multiple species of Phoreiobothrium from the blacktip shark,
… tropical and warm temperate waters. As yet, 34 species of cestodes representing the orders Tetraphyllidea, Cathetocephalidea, and Trypanorhyncha have been reported to parasitize the species throughout its range. Little is known about tetraphyllidean diversity in C. limbatus in the Gulf of …

Reaction and Transport of Multiple Species During Plasma Etching
The nature of transport and reaction of multiple species in plasma reactors was analyzed in order to determine the effect of operating conditions and design variables upon the etch rate distribution and throughput. Epoxy and photoresist films on closely-spaced silicon wafers were etched by reactive …

Comparison of orthologs across multiple species by various strategies
… of genome sequencing technology, abundant multi-species genomic data now became available and comparative genomics continues to be a fast prospering filed of biological research. Through the comparison of genomes of different organisms, we can understand what, at the molecular level, …

Multiple Species of Distinctiveness in Memory: Separating Task Distinctiveness from Statistical Distinctiveness
… project aims to evaluate whether a different species of distinctiveness—statistical distinctiveness—may provide a separate contribution to memory beyond traditional encoding-based processes. Statistical distinctiveness refers to the relative frequency with which a specific memory item or set …

Methods and analysis of genome-scale gene family evolution across multiple species
… generates the diversity of life we see in modern species, specifically the evolution of new genes and functions. By reconstructing the history of the diverse sequences present in modern species, we can improve our understanding of their function and evolutionary importance. Performing such an …

Extension to Multiple Species of a Two-Equation Turbulence Model for High Speed Flows
… </em>turbulence model has been extended to multiple species and implemented in a CFD code for high speed flows using the Steger-Warming flux-vector splitting scheme. The model was chosen because compressibility corrections are not required, nor are viscous damping factors or wall functions …

Multiple-Species Models for True Abundances Allowing for Heterogeneity of Capture Between and Within Species
… animals often differ both within and between species. Previous research involving multiple species' abundances have largely ignored this fact. In this paper, we explore the use of finite mixture modeling to quantify species' true abundances within a population while allowing for unknown …

Blending synthetic pheromones of cerambycid beetles to develop trap lures that simultaneously attract multiple species
We evaluated attraction of cerambycid beetle species to blends of known cerambycid pheromones to determine whether such blends could be used as effective trap lures for detecting and monitoring multiple species simultaneously. Pheromone-baited traps captured 1,358 cerambycid beetles, of which 1,101 …

Investigating single and multiple species fisheries management: stock status evaluation of hammerhead (Sphyrna spp.) sharks in the western North Atlantic Ocean and Gulf of Mexico
… shark complex in the United States. Including multiple species in an assessment ignores the different stock dynamics of each individual species within the complex due to different life histories. This study completed individual assessments of scalloped (S. lewini), great (S. mokarran), and …

Apparent induction, kinetic and physical properties of the multiple species of ornithine decarboxylase, forms A and B, in the kidney and liver of hormone-treated rat
… studies were designed to better characterize the multiple forms of ODC and to investigate the functions and possible origins of ODC A and B in growth hormone, prolactin and/or dexamethasone stimulated tissue. The two species of ODC existed in separate and distinct proportions in control rat kidney …

The Evolution of the Glenoid Region in the Hominidae: Implications for Hominid Phylogenetics
… problematic. Moreover, because individual species of Homo exhibit a wide range of morphological variation, with considerable overlap between species, it is not possible to reject or accept the multiple species hypotheses for either H. habilis or H. erectus. In fact, the recent trend of …

A quantitative model of density-dependent habitat selection: integrating isodar and isoleg theories
… habitat selection, but few models address multiple species interactions and even fewer simulate these phenomena. Moreover, the development of quantitative models that incorporate multiple species interactions is in its infancy with existing models being mostly conceptual and limited in …

Variation in fluctuating asymmetry among nine damselfly species.
… However, comparisons of FA in single damselfly species (Odonata: suborder Zygoptera) from stressed environments have often been inconclusive. We measured levels of FA among multiple species of damselflies from the same environment to determine the relative roles of environmental stress and …

Computational comparative genomics : genes, regulation, evolution
… genes. Comparative genome analysis of related species provides a general approach for identifying these functional elements, by virtue of their stronger conservation across evolutionary time. In this thesis we address key issues in the comparative analysis of multiple species. We present novel …

Analysis and Applications of Fluorescence Fluctuation Spectroscopy
… G(0). This dependence allows to resolve multiple species based on the difference in their molecular brightness, which we applied to a titration study of an antibody with its ligand. The global fit of the average photon counts ⟨k⟩ and the fluctuation amplitude G(0) as a function …

Phenotypic diversity within two toxic dinoflagellate genera : environmental and transcriptomic studies of species diversity in Alexandrium and Gambierdiscus
… ecological roles they play, and the ability of multiple species to produce toxins that affect human and ecosystems health. Two dinoflagellate genera, Alexandrium and Gambierdiscus each contain species that can cause human poisoning syndromes, although the methods of toxin transfer, accumulation, …

Microbial instrumentation utilizing microfluidics
… bacteria live in communities with abundant inter-species chemical communication. To replicate such environments in laboratory conditions, nanoporous microscale microfluidic incubators (NMMIs) for co-culture of multiple species have been developed. The NMMIs enable high-throughput screening and …

Environmental DNA is an Effective Method to Monitor Species in Various Freshwater Habitats
… environment (eDNA) to monitor three amphibian species and two trout species associated with habitat intersected by Interstate-90 in Snoqualmie Pass, Washington. This included a large catchment area within creeks and nearby wetlands historically affected by I-90, including sites where …
