Evidence of infaunal effects on porewater advection and biogeochemistry in permeable sediments: A proposed infaunal functional group framework

Creator:: Waldbusser, George G. and Marinelli, Roberta L.
Abstract:: Bioturbating infauna significantly modify reaction and transport processes in permeable sediments, though most studies to date are limited in the scope of species examined. We conducted a comparative field study measuring density-dependent effects of six common bioturbating species on porewater advection and biogeochemistry, across three intertidal permeable sediment habitats. The...

Composition and major sources of organic compounds of aerosol particulate matter sampled during the ACE-Asia campaign

Creator:: Simoneit, Bernd R. T., Kobayashi, Minoru, Mochida, Michihiro, Kawamura, Kimitaka, Lee, Meehye, Lim, Ho-Jin, Turpin, Barbara J., and Komazaki, Yuichi
Abstract:: The organic compound tracers of atmospheric particulate matter, as well as organic carbon (OC) and elemental carbon (EC), have been characterized for samples acquired during the Asian Pacific Regional Aerosol Characterization Experiment (ACE-Asia) from Gosan, Jeju Island, Korea, from Sapporo, Japan, and from Chichi-jima Island in the western North Pacific,...

Internal waves and tides in the western Weddell Sea: Observations from Ice Station Weddell

Creator:: Levine, Murray D., Padman, Laurie, Muench, Robin D., and Morison, James H.
Abstract:: The upper ocean current and temperature fields in the western Weddell Sea were measured from the drifting pack ice at Ice Station Weddell 1 (ISW) and nearby sites using a vertical profiler and an array of moored sensors in January–June 1992. These data document the structure and variability of the...

Assessing Library Scholarship: Experience at a Land Grant University

Creator:: Wirth, Andrea A., Kelly, Maureen, and Webster, Janet
Abstract:: Library faculty are often tenure track, requiring a record of significant publishing and service before achieving tenure. However, meaningful tools and methods for evaluating the scholarship of librarianship frequently fall short of providing an accurate picture of the scholarship of any particular candidate. The authors conducted a case study analyzing...

High-Throughput Sequencing of Arabidopsis microRNAs : Evidence for Frequent Birth and Death of MIRNA Genes

Creator:: Fahlgren, Noah, Howell, Miya D., Kasschau, Kristin D., Sullivan, Christopher M., Cumbie, Jason S., Givan, Scott A., Law, Theresa F., Grant, Sarah R., Dangl, Jeffrey L., and Carrington, James C.
Abstract:: In plants, microRNAs (miRNAs) comprise one of two classes of small RNAs that function primarily as negative regulators at the posttranscriptional level. Several MIRNA genes in the plant kingdom are ancient, with conservation extending between angiosperms and the mosses, whereas many others are more recently evolved. Here, we use deep...

D-Lactate metabolism and the obligate requirement for CO2 during growth on nitrite by the facultative lithoautotroph Nitrobacter hamburgensis

Creator:: Starkenburg, Shawn R., Arp, Daniel J., and Bottomley, Peter J.
Abstract:: Nitrobacter hamburgensis X14 is a facultative lithoautotroph that conserves energy from the oxidation of nitrite (NO 2 ) and fixes carbon dioxide (CO2) as its sole source of carbon. The availability of the N. hamburgensis X14 genome sequence initiated a re-examination of its mixotrophic and organotrophic potential, as genes encoding...

An Application of Transfer to American Football: From Observation of Raw Video to Control in a Simulated Environment

Creator:: Stracuzzi, David J., Fern, Alan, Ali, Kamal, Hess, Robin, Pinto, Jervis, Li, Nan, Konik, Tolga, and Shapiro, Dan
Abstract:: Automatic transfer of learned knowledge from one task or domain to another offers great potential to simplify and expedite the construction and deployment of intelligent systems. In practice however, there are many barriers to achieving this goal. In this article, we present a prototype system for the real-world context of...

Severe Drought Drives Novel Community Trajectories in Desert Stream Pools

Creator:: Bogan, Michael T. and Lytle, David A.
Abstract:: 1. Ecological communities can be relatively stable for long periods of time, and then, often as a result of disturbance, transition rapidly to a novel state. When communities fail to recover to pre-disturbance configurations, they are said to have experienced a regime shift or to be in an alternative stable state....

Large Predators Limit Herbivore Densities in Northern Forest Ecosystems

Creator:: Ripple, William J. and Beschta, Robert L.
Abstract:: There is a lack of scientific consensus about how top-down and bottom-up forces interact to structure terrestrial ecosystems. This is especially true for systems with large carnivore and herbivore species where the effects of predation versus food limitation on herbivores are controversial. Uncertainty exists whether top-down forces driven by large...

Comparative Composition, Diversity and Trophic Ecology of Sediment Macrofauna at Vents, Seeps and Organic Falls

Creator:: Bernardino, Angelo F., Levin, Lisa A., Thurber, Andrew R., and Smith, Craig R.
Abstract:: Sediments associated with hydrothermal venting, methane seepage and large organic falls such as whale, wood and plant detritus create deep-sea networks of soft-sediment habitats fueled, at least in part, by the oxidation of reduced chemicals. Biological studies at deep-sea vents, seeps and organic falls have looked at macrofaunal taxa, but...
