Magnetic map in nonanadromous Atlantic salmon

Creator:: Scanlan, Michelle M., Putman, Nathan F., Pollock, Amanda M., and Noakes, David L.
Abstract:: Long-distance migrants, including Pacific salmon (Oncorhynchus spp), can use geomagnetic information to navigate. We tested the hypothesis that a “magnetic map” (i.e., an ability to extract positional information from Earth’s magnetic field) also exists in a population of salmon that do not undertake oceanic migrations. This study examined juvenile Atlantic...

Warm spring reduced carbon cycle impact of the 2012 US summer drought

Creator:: Wolf, Sebastian, Keenan, Trevor F., Fisher, Joshua B., Baldocchi, Dennis D., Desai, Ankur R., Richardson, Andrew D., Scott, Russell L., Law, Beverly E., Litvak, Marcy E., Brunsell, Nathaniel A., Peters, Wouter, and van der Laan-Luijkx, Ingrid T.
Abstract:: The global terrestrial carbon sink offsets one-third of the world’s fossil fuel emissions, but the strength of this sink is highly sensitive to large-scale extreme events. In 2012, the contiguous United States experienced exceptionally warm temperatures and the most severe drought since the Dust Bowl era of the 1930s, resulting...

Chemical dispersants can suppress the activity of natural oil-degrading microorganisms

Creator:: Kleindienst, Sara, Seidel, Michael, Ziervogel, Kai, Grim, Sharon, Loftis, Kathy, Harrison, Sarah, Malkin, Sairah Y., Perkins, Matthew J., Field, Jennifer, Sogin, Mitchell L., Dittmar, Thorsten, Passow, Uta, Medeiros, Patricia M., and Joye, Samantha B.
Abstract:: During the Deepwater Horizon oil well blowout in the Gulf of Mexico, the application of 7 million liters of chemical dispersants aimed to stimulate microbial crude oil degradation by increasing the bioavailability of oil compounds. However, the effects of dispersants on oil biodegradation rates are debated. In laboratory experiments, we...

Invasive mammal eradication on islands results in substantial conservation gains

Creator:: Jones, Holly P., Holmes, Nick D., Butchart, Stuart H. M., Tershy, Bernie R., Kappes, Peter J., Corkery, Ilse, Aguirre-Muñoz, Alfonso, Armstrong, Doug P., Bonnaud, Elsa, Burbidge, Andrew A., Campbell, Karl, Courchamp, Franck, Cowan, Philip E., Cuthbert, Richard J., Ebbert, Steve, Genovesi, Piero, Howald, Gregg R., Keitt, Bradford S., Kress, Stephen W., Miskelly, Colin M., Oppel, Steffen, Poncet, Sally, Rauzon, Mark J., Rocamora, Gérard, Russell, James C., Samaniego-Herrera, Araceli, Seddon, Philip J., Spatz, Dena R., Towns, David R., and Croll, Donald A.
Abstract:: More than US$21 billion is spent annually on biodiversity conservation. Despite their importance for preventing or slowing extinctions and preserving biodiversity, conservation interventions are rarely assessed systematically for their global impact. Islands house a disproportionately higher amount of biodiversity compared with mainlands, much of which is highly threatened with extinction....

Deciphering ocean carbon in a changing world

Creator:: Moran, Mary Ann, Kujawinski, Elizabeth B., Stubbins, Aron, Fatland, Rob, Aluwihare, Lihini I., Buchan, Alison, Crump, Byron C., Dorrestein, Pieter C., Dyhrman, Sonya T., Hess, Nancy J., Howe, Bill, Longnecker, Krista, Medeiros, Patricia M., Niggemann, Jutta, Obernosterer, Ingrid, Repeta, Daniel J., and Waldbauer, Jacob R.
Abstract:: Dissolved organic matter (DOM) in the oceans is one of the largest pools of reduced carbon on Earth, comparable in size to the atmospheric CO₂ reservoir. A vast number of compounds are present in DOM, and they play important roles in all major element cycles, contribute to the storage of...

Micromechanics of cellularized biopolymer networks

Creator:: Jones, Christopher A. R., Cibula, Matthew, Feng, Jingchen, Krnacik, Emma A., McIntyre, David H., Levine, Herbert, and Sun, Bo
Abstract:: Collagen gels are widely used in experiments on cell mechanics because they mimic the extracellular matrix in physiological conditions. Collagen gels are often characterized by their bulk rheology; however, variations in the collagen fiber microstructure and cell adhesion forces cause the mechanical properties to be inhomogeneous at the cellular scale....

The genome of Aiptasia, a sea anemone model for coral symbiosis

Creator:: Baumgarten, Sebastian, Simakov, Oleg, Esherick, Lisl Y., Liew, Yi Jin, Lehnert, Erik M., Michell, Craig T., Li, Yong, Hambleton, Elizabeth A., Guse, Annika, Oates, Matt E., Gough, Julian, Weis, Virginia M., Aranda, Manuel, Pringle, John R., and Voolstra, Christian R.
Abstract:: The most diverse marine ecosystems, coral reefs, depend upon a functional symbiosis between a cnidarian animal host (the coral) and intracellular photosynthetic dinoflagellate algae. The molecular and cellular mechanisms underlying this endosymbiosis are not well understood, in part because of the difficulties of experimental work with corals. The small sea...

Backbones of evolutionary history test biodiversity theory for microbes

Creator:: O'Dwyer, James P., Kembel, Steven W., and Sharpton, Thomas J.
Abstract:: Identifying the ecological and evolutionary mechanisms that determine biological diversity is a central question in ecology. In microbial ecology, phylogenetic diversity is an increasingly common and relevant means of quantifying community diversity, particularly given the challenges in defining unambiguous species units from environmental sequence data. We explore patterns of phylogenetic...

Long-term litter decomposition controlled by manganese redox cycling

Creator:: Keiluweit, Marco, Nico, Peter, Harmon, Mark E., Mao, Jingdong, Pett-Ridge, Jennifer, and Kleber, Markus
Abstract:: Litter decomposition is a keystone ecosystem process impacting nutrient cycling and productivity, soil properties, and the terrestrial carbon (C) balance, but the factors regulating decomposition rate are still poorly understood. Traditional models assume that the rate is controlled by litter quality, relying on parameters such as lignin content as predictors....

Nature as capital: Advancing and incorporating ecosystem services in United States federal policies and programs

Creator:: Schaefer, Mark, Goldman, Erica, Bartuska, Ann M., Sutton-Grier, Ariana, and Lubchenco, Jane
Abstract:: The concept of nature as capital is gaining visibility in policies and practices in both the public and private sectors. This change is due to an improved ability to assess and value ecosystem services, as well as to a growing recognition of the potential of an ecosystem services approach to...
