Cold Seep Epifaunal Communities on the Hikurangi Margin, New Zealand: Composition, Succession, and Vulnerability to Human Activities

Creator:: Bowden, David A., Rowden, Ashley A., Thurber, Andrew R., Baco, Amy R., Levin, Lisa A., and Smith, Craig R.
Abstract:: Cold seep communities with distinctive chemoautotrophic fauna occur where hydrocarbon-rich fluids escape from the seabed. We describe community composition, population densities, spatial extent, and within-region variability of epifaunal communities at methane-rich cold seep sites on the Hikurangi Margin, New Zealand. Using data from towed camera transects, we match observations to...

Evaluating taxonomic homogenization of freshwater fish assemblages in Chile

Creator:: Vargas, Pamela V., Arismendi, Ivan, and Gomez-Uchida, Daniel
Abstract:: Background: Pervasive introductions of non-native taxa are behind processes of homogenization of various types affecting the global flora and fauna. Chile's freshwater ecosystems encompass a diverse and highly endemic fish fauna that might be sensitive to the introduction of non-native species, an ongoing process that started two centuries ago, but...

Targeting an Essential GTPase Obg for the Development of Broad-Spectrum Antibiotics

Creator:: Bonventre, Josephine A., Zielke, Ryszard A., Korotkov, Konstantin V., and Sikora, Aleksandra E.
Abstract:: A promising new drug target for the development of novel broad-spectrum antibiotics is the highly conserved small GTPase Obg (YhbZ, CgtA), a protein essential for the survival of all bacteria including Neisseria gonorrhoeae (GC). GC is the agent of gonorrhea, a prevalent sexually transmitted disease resulting in serious consequences on...

Cupric Oxide (CuO) Oxidation Detects Pyrogenic Carbon in Burnt Organic Matter and Soils

Creator:: Hatten, Jeff and Goñi, Miguel
Abstract:: Wildfire greatly impacts the composition and quantity of organic carbon stocks within watersheds. Most methods used to measure the contributions of fire altered organic carbon–i.e. pyrogenic organic carbon (Py-OC) in natural samples are designed to quantify specific fractions such as black carbon or polyaromatic hydrocarbons. In contrast, the CuO oxidation...

Quantifying predator dependence in the functional response of generalist predators

Creator:: Novak, Mark, Wolf, Christopher, Coblentz, Kyle E., and Shepard, Isaac D.
Abstract:: A long-standing debate concerns how functional responses are best described. Theory suggests that ratio dependence is consistent with many food web patterns left unexplained by the simplest prey-dependent models. However, for logistical reasons, ratio dependence and predator dependence more generally have seen infrequent empirical evaluation and then only so in...

Flux: Insights into the Social Aspects of Life Transitions

Creator:: Settersten, Richard A., Jr. and Thogmartin, Asia
Abstract:: Life transitions are often conceptualized and studied as individual experiences. But in reality, transitions are rarely individual: they are relational. We offer a set of insights into the social aspects of transitions. Transitions are experienced with and alongside others in states of interdependence. Family and other relationships can be key...

Probing Aqueous Ion-Pairing and Speciation of Group V Polyoxometalates

Creator:: Sures, Dylan J.
Abstract:: Polyoxometalates are discrete anionic oxo clusters of the Group V and VI transition metals that can be conceptualized as molecular metal oxides. Because they are pairable with any alkali cation, a great deal of fundamental chemistry can be gleaned from their study, including solubility trends and insight into cation binding...

Spatiotemporal distribution of the anti-diabetic drug, metformin, in the lower Columbia River and its effect on phytoplankton growth

Creator:: Cummings, Brittany M.
Abstract:: Water quality impacts both human and ecosystem health. Many pharmaceuticals and personal care products are considered contaminants of emerging concern (CEC) due to their bioactive properties. Among these, metformin—the most commonly prescribed drug for treatment of type 2 diabetes—has been reported at high concentrations (μg L⁻¹) in stream, lake, and...

Leaf-level physiology in four subalpine plants in tephra-impacted forests during drought

Creator:: Watt, Abby J., Fischer, Dylan G., Antos, Joseph A., and Zobel, Donald B.
Abstract:: Ecological impacts of climate change in the Pacific Northwest may hinge on acclimation to drier summers, highlighting the importance of plant physiological studies in forests. Evaluating dominant forest plant species under old-growth and managed forest conditions is similarly important as timber harvest might change microclimates and alter drought effects on...
