Using Gis Mapping Of The Extent Of Nearshore Rocky Reefs To Estimate The Abundance And Reproductive Output Of Important Fishery Species, Jeremy Claisse, Daniel Pondella, Jonathan Williams, James Sadd

James Sadd

Kelp Bass (Paralabrax clathratus) and California Sheephead (Semicossyphus pulcher) are economically and ecologically valuable rocky reef fishes in southern California, making them likely indicator species for evaluating resource management actions. Multiple spatial datasets, aerial and satellite photography, underwater observations and expert judgment were used to produce a comprehensive map of nearshore natural rocky reef habitat for the Santa Monica Bay region (California, USA). It was then used to examine the relative contribution of individual reefs to a regional estimate of abundance and reproductive potential of the focal species. For the reefs surveyed for fishes (i.e. 18 …

Is Your Learning Style Paranoid?, Kirby Farrell

kirby farrell

We learn—and grow—by engaging with anomalies: new things that don't fit our familiar categories. It's a gut process, not just a philosophical choice. Anxiety can make us paranoid about what's new and strange. Knowing that can spur fascination and help us to adapt.

Changes In Microbial Communities Along Redox Gradients In Polygonized Arctic Wet Tundra Soils, David A. Lipson, Ted K. Raab, Melanie Parker, Scott T. Kelley, Colin J. Brislawn, Janet Jansson

Ted K. Raab

This study investigated how microbial community structure and diversity varied with depth and topography in ice wedge polygons of wet tundra of the Arctic Coastal Plain in northern Alaska, and what soil variables explain these patterns. We observed strong changes in community structure and diversity with depth, and more subtle changes between areas of high and low topography, with the largest differences apparent near the soil surface. These patterns are most strongly correlated with redox gradients (measured using the ratio of reduced Fe to total Fe in acid extracts as a proxy): conditions grew more reducing with depth and were …

New Records Of Merriam’S Shrew (Sorex Merriami) From Western North Dakota, Michael J. Shaughnessy Jr., Neal Woodman

Neal Woodman

Despite having a broad geographic distribution, Merriam’s Shrew (Sorex merriami Dobson 1890) is known from a relatively few, widely-scattered localities. In North Dakota, the species was known from only a single poorly-preserved specimen collected in 1913 near Medora. We recently collected two new specimens of Merriam’s Shrew from Billings and McKenzie counties in the western quarter of the state. These specimens confirm the presence of S. merriami in North Dakota and better define the northeastern edge of the species’ distribution.

Evolution Of The Influenza A Virus Genome During Development Of Oseltamivir Resistance In Vitro, Nicholas Renzette, Daniel Caffrey, Konstantin Zeldovich, Ping Liu, Glen Gallagher, Daniel Aiello, Alyssa Porter, Evelyn Kurt-Jones, Daniel Bolon, Yu-Ping Poh, Jeffrey Jensen, Celia Schiffer, Timothy Kowalik, Robert Finberg, Jennifer Wang

Glen R. Gallagher

Influenza A virus (IAV) is a major cause of morbidity and mortality throughout the world. Current antiviral therapies include oseltamivir, a neuraminidase inhibitor that prevents the release of nascent viral particles from infected cells. However, the IAV genome can evolve rapidly, and oseltamivir resistance mutations have been detected in numerous clinical samples. Using an in vitro evolution platform and whole-genome population sequencing, we investigated the population genomics of IAV during the development of oseltamivir resistance. Strain A/Brisbane/59/2007 (H1N1) was grown in Madin-Darby canine kidney cells with or without escalating concentrations of oseltamivir over serial passages. Following drug treatment, the H274Y …

An Individual-Based Model For Feral Hogs In Great Smoky Mountains National Park, Rene A. Salinas, William H. Stiver, Joseph L. Corn, Suzanne Lenhart, Charles Colin, Marguerite Madden, Kurt C. Vercauteren, Brandon B. Schmit, Ellen Kasari, Agricola Odoi, Graham Hickling, Hamish Mccallum

Agricola Odoi

The expansion of feral hog (Sus scrofa)populations in the United States has resulted in increased efforts to develop and implement control strategies designed to minimize the impacts done by this invasive species. We describe an individual-based model for feral hogs in Great Smoky Moun- tains National Park (GSMNP). The objectives of the model are to provide an understanding of the population dynamics of this feral hog population and to determine the efficacy of the annual harvest as a population control method. Results suggest that the dynamics of the population are driven by fall hard mast production and the GSMNP harvests …

Economics Of The Queensland Mud Crab Fishery, Tor Hundloe

Tor Hundloe

A series of analyses of catch-effort data from compulsory commercial logbooks and from the Department’s Long-Term Monitoring Programme (LTMP) were conducted after the Workshop. Although not part of the Project plan, these were initiated as a result of questions arising from the Workshop participants about the reliability of the data used in the simulation modelling. Exploration of the logbook data and results of the analyses suggest that biases in the data (from a variety of sources, but principally the widespread use of more than the permitted number of pots) may be giving an over-optimistic view of the status of the …

The Molecular Dimension Of Microbial Species: 3. Comparative Genomics Of Synechococcus Strains With Different Light Responses And In Situ Diel Transcription Patterns Of Associated Putative Ecotypes In The Mushroom Spring Microbial Mat, Millie Olsen, Shane Nowack, Jason Wood, Eric Becraft, Kurt Labutti, Anna Lipzen, Joel Martin, Wendy Shackwitz, Douglas Rusch, Frederick Cohan, Donald Bryant, David Ward

Frederick M. Cohan

Genomes were obtained for three closely related strains of Synechococcus that are representative of putative ecotypes that predominate at different depths in the 1 mm-thick, upper-green layer in the 60°C mat of Mushroom Spring, Yellowstone National Park, and exhibit different light adaptation and acclimation responses. The genomes were compared to the published genome of a previously obtained, closely related strain from a neighboring spring, and differences in both gene content and orthologous gene alleles between high-light-adapted and low-light-adapted strains were identified. Evidence of genetic differences that relate to adaptation to light intensity and/or quality, CO2 uptake, nitrogen metabolism, organic carbon …

Wood, Douglas B. Rusch, Michael Kuhl, Sheila Jensen, Donald A. Bryant, David W. Roberts, Frederick M. Cohan, David M. Ward

Frederick M. Cohan

Based on the Stable Ecotype Model, evolution leads to the divergence of ecologically distinct populations (e.g., with different niches and/or behaviors) of ecologically interchangeable membership. In this study, pyrosequencing was used to provide deep sequence coverage of Synechococcus psaA genes (encoding a photosystem I reaction center protein subunit) and transcripts over a large number of habitat types in the Mushroom Spring microbial mat. Putative ecological species (putative ecotypes), which were predicted by an evolutionary simulation based on the Stable Ecotype Model (Ecotype Simulation), exhibited distinct distributions relative to temperature-defined positions in the effluent channel and vertical position in the upper …

An Assessment Of South China Tiger Reintroduction Potential In Hupingshan And Houhe National Nature Reserves, China, Yiyuan Qin, Philip J. Nyhus, Courtney L. Larson, Charles J.W. Carroll, Jeff Muntifering, Thomas D. Dahmer, Lu Jun, Ronald L. Tilson

Philip J. Nyhus

Human-caused biodiversity loss is a global problem, large carnivores are particularly threatened, and the tiger (Panthera tigris) is among the world’s most endangered large carnivores. The South China tiger (Panthera tigris amoyensis) is the most critically endangered tiger subspecies and is considered functionally extinct in the wild. The government of China has expressed its intent to reintroduce a small population of South China tigers into a portion of their historic range as part of a larger goal to recover wild tiger populations in China. This would be the world’s first major tiger reintroduction program. A free-ranging population of 15–20 tigers …

Impacts Of People And Tigers On Leopard Spatiotemporal Activity Patterns In A Global Biodiversity Hotspot, Neil Carter, Micah Jasny, Bhim Gurung, Jianguo Liu

Neil H. Carter

Leopard population declines largely occur in areas where leopards and people frequently interact. Research on how leopards respond to human presence and competitors, like other predators, can provide important insights on leopard ecology and conservation in human-dominated regions; however, such research is lacking. Here we used data from field cameras in 2010 and 2011 to examine how human presence, prey, and tigers influence leopard spatiotemporal activity patterns in and around Nepal’s Chitwan National Park, part of a global biodiversity hotspot. We found that leopards were adjusting their spatiotemporal activity patterns to both tigers and people, but by different mechanisms. Leopards …

Variation In The Myosoricine Hand Skeleton And Its Implications For Locomotory Behavior (Eulipotyphla: Soricidae), Neal Woodman, Frank A. Stabile

Neal Woodman

Substrate use and locomotory behavior of mammals are typically reflected in external characteristics of the forefeet, such as the relative proportions of the digits and claws. Although skeletal anatomy of the forefeet can be more informative than external characters, skeletons remain rare in systematic collections. This is particularly true for the Myosoricinae (Eulipotyphla: Soricidae), a small clade of African shrews that includes both ambulatory forest shrews (Myosorex) and semifossorial mole shrews (Surdisorex). Most species in this subfamily have restricted distributions, and their behavior and ecology are mostly unstudied. To better understand the potential range of locomotory behavior among myosoricines, we …
