Evaluating Temporal Consistency in Marine Biodiversity Hotspots

Creator:: Piacenza, Susan E., Thurman, Lindsey L., Barner, Allison K., Benkwitt, Cassandra E., Boersma, Kate S., Cerny-Chipman, Elizabeth B., Ingeman, Kurt E., Kindinger, Tye L., Lindsley, Amy J., Nelson, Jake, Reimer, Jessica N., Rowe, Jennifer C., Shen, Chenchen, Thompson, Kevin A., and Heppell, Selina S.
Abstract:: With the ongoing crisis of biodiversity loss and limited resources for conservation, the concept of biodiversity hotspots has been useful in determining conservation priority areas. However, there has been limited research into how temporal variability in biodiversity may influence conservation area prioritization. To address this information gap, we present an...

Sources and Levels of Ambient Ocean Sound near the Antarctic Peninsula

Creator:: Dziak, Robert P., Bohnenstiehl, DelWayne R., Stafford, Kathleen M., Matsumoto, Haruyoshi, Park, Minkyu, Lee, Won Sang, Fowler, Matt J., Lau, Tai-Kwan, Haxel, Joseph H., and Mellinger, David K.
Abstract:: Arrays of hydrophones were deployed within the Bransfield Strait and Scotia Sea (Antarctic Peninsula region) from 2005 to 2009 to record ambient ocean sound at frequencies of up to 125 and 500 Hz. Icequakes, which are broadband, short duration signals derived from fracturing of large free-floating icebergs, are a prominent...

How Effective Are DNA Barcodes in the Identification of African Rainforest Trees?

Creator:: Parmentier, Ingrid, Duminil, Jérôme, Kuzmina, Maria, Philippe, Morgane, Thomas, Duncan W., Kenfack, David, Chuyong, George B., Cruaud, Corinne, and Hardy, Olivier J.
Abstract:: Background: DNA barcoding of rain forest trees could potentially help biologists identify species and discover new ones. However, DNA barcodes cannot always distinguish between closely related species, and the size and completeness of barcode databases are key parameters for their successful application. We test the ability of rbcL, matK and...

An Online Database for Informing Ecological Network Models: http://kelpforest.ucsc.edu

Creator:: Beas-Luna, Rodrigo, Novak, Mark, Carr, Mark H., Tinker, Martin T., Black, August, Caselle, Jennifer E., Hoban, Michael, Malone, Dan, and Iles, Alison
Abstract:: Ecological network models and analyses are recognized as valuable tools for understanding the dynamics and resiliency of ecosystems, and for informing ecosystem-based approaches to management. However, few databases exist that can provide the life history, demographic and species interaction information necessary to parameterize ecological network models. Faced with the difficulty...

Delayed Cutaneous Wound Healing and Aberrant Expression of Hair Follicle Stem Cell Markers in Mice Selectively Lacking Ctip2 in Epidermis

Creator:: Liang, Xiaobo, Bhattacharya, Shreya, Bajaj, Gaurav, Guha, Gunjan, Wang, Zhixing, Jang, Hyo-Sang, Leid, Mark, Indra, Arup Kumar, and Ganguli-Indra, Gitali
Abstract:: Background: COUP-TF interacting protein 2 [(Ctip2), also known as Bcl11b] is an important regulator of skin homeostasis, and is overexpressed in head and neck cancer. Ctip2(ep-/-) mice, selectively ablated for Ctip2 in epidermal keratinocytes, exhibited impaired terminal differentiation and delayed epidermal permeability barrier (EPB) establishment during development, similar to what...

A Multi-Year Longitudinal Study of Water Quality Parameters in Four Salmon-Bearing and Recreational Streams on Mount Hood, Oregon

Creator:: Wasowski, Ronald, Alexander, David, Kolmes, Steven, Banet, Nathan, Card, Amy, Haines, Morgan, Kolmes, Elijah, Northcutt, Kelly, Roemer, Derek, and Webber, Sarah
Abstract:: Four streams-Clear Fork, Lost Creek, Camp Creek and Still Creek-in northwestern Oregon's Sandy River Basin were monitored for temperature, dissolved oxygen levels, and fecal bacterial concentrations in a multi-year analysis examining stream health for recreational users and anchor habitat for Pacific Salmon. Temperatures were recorded using micro -T temperature loggers...

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...

Ocean Acidification Has Multiple Modes of Action on Bivalve Larvae

Creator:: Waldbusser, George G., Hales, Burke, Langdon, Chris J., Haley, Brian A., Schrader, Paul, Brunner, Elizabeth L., Gray, Matthew W., Miller, Cale A., Gimenez, Iria, and Hutchinson, Greg
Abstract:: Ocean acidification (OA) is altering the chemistry of the world’s oceans at rates unparalleled in the past roughly 1 million years. Understanding the impacts of this rapid change in baseline carbonate chemistry on marine organisms needs a precise, mechanistic understanding of physiological responses to carbonate chemistry. Recent experimental work has...

Recruitment, Growth and Mortality of an Antarctic Hexactinellid Sponge, Anoxycalyx joubini

Creator:: Dayton, Paul K., Kim, Stacy, Jarrell, Shannon C., Oliver, John S., Hammerstrom, Kamille, Fisher, Jennifer L., O'Connor, Kevin, Barber, Julie S., Robilliard, Gordon, Barry, James, Thurber, Andrew R., and Conlan, Kathy
Abstract:: Polar ecosystems are sensitive to climate forcing, and we often lack baselines to evaluate changes. Here we report a nearly 50-year study in which a sudden shift in the population dynamics of an ecologically important, structure-forming hexactinellid sponge, Anoxycalyx joubini was observed. This is the largest Antarctic sponge, with individuals...

Can Observation Skills of Citizen Scientists Be Estimated Using Species Accumulation Curves?

Creator:: Kelling, Steve, Johnston, Alison, Hochachka, Wesley M., Iliff, Marshall, Fink, Daniel, Gerbracht, Jeff, Lagoze, Carl, La Sorte, Frank A., Moore, Travis, Wiggins, Andrea, Wong, Weng-Keen, Wood, Chris, and Yu, Jun
Abstract:: Volunteers are increasingly being recruited into citizen science projects to collect observations for scientific studies. An additional goal of these projects is to engage and educate these volunteers. Thus, there are few barriers to participation resulting in volunteer observers with varying ability to complete the project’s tasks. To improve the...
