Clarifying the Dominant Sources and Mechanisms of Cirrus Cloud Formation

Creator:: Cziczo, Daniel J., Froyd, Karl D., Hoose, Corinna, Jensen, Eric J., Diao, Minghui, Zondlo, Mark A., Smith, Jessica B., Twohy, Cynthia H., and Murphy, Daniel M.
Abstract:: Formation of cirrus clouds depends on the availability of ice nuclei to begin condensation of atmospheric water vapor. Although it is known that only a small fraction of atmospheric aerosols are efficient ice nuclei, the critical ingredients that make those aerosols so effective have not been established. We have determined...

Boom-bust Cycles in Gray Whales Associated with Dynamic and Changing Arctic Conditions

Creator:: Stewart, Joshua D., Joyce, Trevor W., Durban, John W., Calambokidis, John, Fauquier, Deborah, Fearnbach, Holly, Grebmeier, Jacqueline M., Lynn, Morgan, Manizza, Manfredi, Perryman, Wayne L., Tinker, M. Tim, and Weller, David W.
Abstract:: Climate change is impacting a wide range of global systems, with polar ecosystems experiencing the most rapid change. While climate impacts affect lower trophic level and short-lived species most directly, it is less clear how long-lived and mobile species will respond to rapid polar warming, as they may have the...

Hydrologic connectivity constrains partitioning of global terrestrial water fluxes

Creator:: Good, Stephen P., Noone, David, and Bowen, Gabriel
Abstract:: Continental precipitation not routed to the oceans as runoff returns to the atmosphere as evapotranspiration. Partitioning this evapotranspiration flux into interception, transpiration, soil evaporation, and surface water evaporation is difficult using traditional hydrological methods yet critical for understanding the water cycle and linked ecological processes. We combined two large-scale flux-partitioning...

Sidewinding with minimal slip: Snake and robot ascent of sandy slopes

Creator:: Marvi, Hamidreza, Gong, Chaohui, Gravish, Nick, Astley, Henry, Travers, Matthew, Hatton, Ross L., Mendelson, Joseph R., III, Choset, Howie, Hu, David L., and Goldman, Daniel I.
Abstract:: Limbless organisms like snakes can navigate nearly all terrain. In particular, desert-dwelling sidewinder rattlesnakes (C. cerastes) operate effectively on inclined granular media (like sand dunes) that induce failure in field-tested limbless robots through slipping and pitching. Our laboratory experiments reveal that as granular incline angle increases, sidewinder rattlesnakes increase the...

Greenland Temperature Response to Climate Forcing during the Last Deglaciation

Creator:: Buizert, Christo, Gkinis, Vasileios, Severinghaus, Jeffrey P., He, Feng, Lecavalier, Benoit S., Kindler, Philippe, Leuenberger, Markus, Carlson, Anders E., Vinther, Bo, Masson-Delmotte, Valerie, White, James W. C., Liu, Zhengyu, Otto-Bliesner, Bette, and Brook, Edward J.
Abstract:: Greenland ice core water isotopic composition (δ¹⁸O) provides detailed evidence for abrupt climate changes, but is by itself insufficient for quantitative reconstruction of past temperatures and their spatial patterns. We investigate Greenland temperature evolution during the last deglaciation using independent reconstructions from three ice cores and simulations with a coupled...

Shadow Enhancers as a Source of Evolutionary Novelty

Creator:: Hong, Joung-Woo, Hendrix, David A., and Levine, Michael S.
Abstract:: The dorsal-ventral patterning of the Drosophila embryo is controlled by Dorsal, a sequence-specific transcription factor that is related to mammalian NF-κB. Previous ChIP-chip assays predicted that as many as a third or even half of all Dorsal target genes contain multiple enhancers for the same or similar expression pattern. Here...

Low Coseismic Friction on the Tohoku-Oki Fault Determined from Temperature Measurements

Creator:: Fulton, P. M., Brodsky, E. E., Kano, Y., Mori, J., Chester, F., Ishikawa, T., Harris, R. N., Lin, W., Eguchi, N., Toczko, S., Expedition 343 Scientists, Expedition 343T Scientists, and Expedition KR13-08 Scientists
Abstract:: The frictional resistance on a fault during slip controls earthquake dynamics. Friction dissipates heat during an earthquake; therefore the fault temperature after an earthquake provides insight into the level of friction. The JFAST project (IODP Expedition 343/343T) installed a borehole temperature observatory 16 months after the March 2011 M[subscript w]9.0...

Constraints on the Late Holocene Anthropogenic Contribution to the Atmospheric Methane Budget

Creator:: Mitchell, Logan, Brook, Edward J., Lee, James E., Buizert, Christo, and Sowers, Todd
Abstract:: The origin of the late pre-industrial Holocene (LPIH) increase in atmospheric methane concentrations has been much debated. Hypotheses invoking changes in solely anthropogenic sources or solely natural sources have been proposed to explain the increase in concentrations. Here two high-resolution, high-precision ice core methane concentration records from Greenland and Antarctica...

Status and Ecological Effects of the World’s Largest Carnivores

Creator:: Ripple, William J., Estes, James A., Beschta, Robert L., Wilmers, Christopher C., Ritchie, Euan G., Hebblewhite, Mark, Berger, Joel, Elmhagen, Bodil, Letnic, Mike, Nelson, Michael P., Schmitz, Oswald J., Smith, Douglas W., Wallach, Arian D., and Wirsing, Aaron J.
Abstract:: Large carnivores face serious threats and are experiencing massive declines in their populations and geographic ranges around the world. We highlight how these threats have affected the conservation status and ecological functioning of the 31 largest mammalian carnivores on Earth. Consistent with theory, empirical studies increasingly show that large carnivores...

Soil Diversity and Hydration as Observed by ChemCam at Gale Crater, Mars

Abstract:: Abstract: The ChemCam instrument, which provides insight into martian soil chemistry at the submillimeter scale, identified two principal soil types along the Curiosity rover traverse: a fine-grained mafic type and a locally derived, coarse-grained felsic type. The mafic soil component is representative of widespread martian soils and is similar in...
