ARTHROPOD COMMUNITIES and PASSERINE DIET: EFFECTS of SHRUB EXPANSION in WESTERN ALASKA by Molly Tankersley Mcdermott, B.A./B.S
Arthropod communities and passerine diet: effects of shrub expansion in Western Alaska Item Type Thesis Authors McDermott, Molly Tankersley Download date 26/09/2021 06:13:39 Link to Item http://hdl.handle.net/11122/7893 ARTHROPOD COMMUNITIES AND PASSERINE DIET: EFFECTS OF SHRUB EXPANSION IN WESTERN ALASKA By Molly Tankersley McDermott, B.A./B.S. A Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Science in Biological Sciences University of Alaska Fairbanks August 2017 APPROVED: Pat Doak, Committee Chair Greg Breed, Committee Member Colleen Handel, Committee Member Christa Mulder, Committee Member Kris Hundertmark, Chair Department o f Biology and Wildlife Paul Layer, Dean College o f Natural Science and Mathematics Michael Castellini, Dean of the Graduate School ABSTRACT Across the Arctic, taller woody shrubs, particularly willow (Salix spp.), birch (Betula spp.), and alder (Alnus spp.), have been expanding rapidly onto tundra. Changes in vegetation structure can alter the physical habitat structure, thermal environment, and food available to arthropods, which play an important role in the structure and functioning of Arctic ecosystems. Not only do they provide key ecosystem services such as pollination and nutrient cycling, they are an essential food source for migratory birds. In this study I examined the relationships between the abundance, diversity, and community composition of arthropods and the height and cover of several shrub species across a tundra-shrub gradient in northwestern Alaska. To characterize nestling diet of common passerines that occupy this gradient, I used next-generation sequencing of fecal matter. Willow cover was strongly and consistently associated with abundance and biomass of arthropods and significant shifts in arthropod community composition and diversity. -
Tigersharc DSP Hardware Specification, Revision 1.0.2, Direct Memory Access
7 DIRECT MEMORY ACCESS Figure 7-0. Table 7-0. Listing 7-0. Overview Direct Memory Access (DMA) is a mechanism for transferring data with- out core being involved. The TigerSHARC® DSP’s on-chip DMA controller relieves the core processor of the burden of moving data between internal memory and an external device, external memory, or between link ports and internal or external memory. The fully-integrated DMA controller allows the TigerSHARC® DSP core processor, or an external device, to specify data transfer operations and return to normal processing while the DMA controller carries out the data transfers in the background. The TigerSHARC® DSP DMA competes with other masters for internal memory access. For more information, see “Architecture and Microarchi- tecture Overview” on page 6-7. This conflict is minimized due to the large internal memory bandwidth that is available. The DMA includes 14 DMA channels, four of which are dedicated to external memory devices, eight to link ports, and two to AutoDMA registers. TigerSHARC DSP Hardware Specification 7 - 1 Overview Figure 7-1 shows a block diagram of the TigerSHARC® DSP’s DMA controller. TRANSMITTER RECEIVER TCB TCB REGISTERS REGISTERS Internal DMA DMA CONTROLLER Bus Requests Interface Figure 7-1. DMA Block Diagram Data Transfers — General Information The DMA controller can perform several types of data transfers: • Internal memory ⇒ external memory and memory-mapped periph- erals • Internal memory ⇒ internal memory of other TigerSHARC® DSPs residing on the cluster bus • Internal memory ⇒ host processor • Internal memory ⇒ link port I/O • External memory ⇒ external peripherals 7 - 2 TigerSHARC DSP Hardware Specification Direct Memory Access • External memory ⇒ internal memory • External memory ⇒ link port I/O • Link port I/O ⇒ internal memory • Link port I/O ⇒ external memory • Cluster bus master via AutoDMA registers ⇒ internal memory Internal-to-internal memory transfers are not directly supported. -

Altogether one species of Bolitophilidae, 16 species of Keroplatidae and 105 species of Mycetophilidae are recognised as occurring in Sardinia. As the bolitophilid and two of the mycetophilid species are represented only by females and are not determined to species level, the total confirmed Sardinian list stands at 119 species. Four species of Keroplatidae and 19 species of Mycetophilidae are new to the total Italian fauna, whereas three species of Keroplatidae and 32 species of Mycetophilidae are newly recorded for the island of Sardinia. Six species are described as new to science: two Keroplatidae (Urytalpa juliae sp. nov., Macrocera nuragica sp. nov.) and four Mycetophilidae (Boletina ichnusa sp. nov., Trichonta sandalyon sp. -

Sensitivity and Specificity. Wikipedia. Last Modified on 16 November 2013
Sensitivity and specificity - Wikipedia, the free encyclopedia Create account Log in Article Talk Read Edit View Sensitivity and specificity From Wikipedia, the free encyclopedia Main page Contents Sensitivity and specificity are statistical measures of the performance of a binary classification test, also known in statistics as Featured content classification function. Sensitivity (also called the true positive rate, or the recall rate in some fields) measures the proportion of Current events actual positives which are correctly identified as such (e.g. the percentage of sick people who are correctly identified as having Random article the condition). Specificity measures the proportion of negatives which are correctly identified as such (e.g. the percentage of Donate to Wikipedia healthy people who are correctly identified as not having the condition, sometimes called the true negative rate). These two measures are closely related to the concepts of type I and type II errors. A perfect predictor would be described as 100% Interaction sensitive (i.e. predicting all people from the sick group as sick) and 100% specific (i.e. not predicting anyone from the healthy Help group as sick); however, theoretically any predictor will possess a minimum error bound known as the Bayes error rate. About Wikipedia For any test, there is usually a trade-off between the measures. For example: in an airport security setting in which one is testing Community portal for potential threats to safety, scanners may be set to trigger on low-risk items like belt buckles and keys (low specificity), in Recent changes order to reduce the risk of missing objects that do pose a threat to the aircraft and those aboard (high sensitivity). -

To examine the biogeographic history of Tsuga, phylogenetic relationships among multiple accessions of all nine species were inferred using chloroplast DNA sequences and multiple cloned sequences of the nuclear ribosomal ITS region. Analysis of chloroplast and ITS sequences resolve a clade that includes the two western North American species, T. heterophylla and T. mertensiana, and a clade of Asian species within which one of the eastern North American species, T. caroliniana, is nested. The other eastern North American species, T. canadensis, is sister to the Asian clade. Tsuga chinensis from Taiwan did not group with T. -
