Microhabitat selection of brood-rearing sites by greater sage-grouse in Carbon County, Wyoming

Creator:: Schreiber, Leslie A.
Abstract:: Declines in Greater Sage-Grouse (Centrocercus urophasianus, hereafter sage-grouse) populations could be attributed to low chick survival, which may be influenced by the availability of food and cover at sites used by females rearing broods. Habitat attributes important to broods may vary regionally; thus, it is necessary to understand factors affecting...

Linking top-down forces to the pleistocene megafaunal extinctions

Creator:: Ripple, William J. and Van Valkenburgh, Blaire
Abstract:: Humans, in conjunction with natural top-down processes and through a sequence of cascading trophic interactions, may have contributed to the Pleistocene megafaunal extinctions. The arrival of the first humans, as hunters and scavengers, through top-down forcing, could have triggered a population collapse of large herbivores and their predators. We present...

Overfishing and nutrient pollution interact with temperature to disrupt coral reefs down to microbial scales

Creator:: Zaneveld, Jesse R., Rosales, Stephanie, Fuchs, Corinne, Maynard, Jeffrey A., Thurber, Rebecca Vega, Burkepile, Deron E., Shantz, Andrew A., Pritchard, Catharine E., McMinds, Ryan, Payet, Jérôme P., Welsh, Rory, Correa, Adrienne M. S., and Lemoine, Nathan P.
Abstract:: Losses of corals worldwide emphasize the need to understand what drives reef decline. Stressors such as overfishing and nutrient pollution may reduce resilience of coral reefs by increasing coral–algal competition and reducing coral recruitment, growth and survivorship. Such effects may themselves develop via several mechanisms, including disruption of coral microbiomes....

The potential for top-down control on tropical tunas based on size structure of predator-prey interactions

Creator:: Hunsicker, Mary E., Olson, Robert J., Essington, Timothy E., Maunder, Mark N., Duffy, Leanne M., and Kitchell, James F.
Abstract:: The ecological consequences of widespread fisheries-induced reductions of large pelagic predators are not fully understood. Tropical tunas are considered a main component of apex predator guilds that include sharks and billfishes, and thus may seem unsusceptible to secondary effects of fishing top predators. However, intra-guild predation can occur because of...

Swash zone boundary conditions derived from optical remote sensing of swash zone flow patterns

Creator:: Power, H. E., Holman, R. A., and Baldock, T. E.
Abstract:: Optical remote sensing is used to measure flow patterns in the swash zone. Timestack images are analyzed to measure the asymmetry and the relative duration of the inflow into the swash zone. This varies significantly between individual swashes, contrary to the classical analytical swash model for runup induced by bores,...

Population growth across heterogeneous environments: effects of harvesting and age structure

Creator:: Durant, Joel M., Hidalgo, Manuel, Rouyer, Tristan, Hjermann, Dag O., Ciannelli, Lorenzo, Eikeset, Anne Maria, Yaragina, Natalia, and Stenseth, N. C.
Abstract:: Population growth is affected by several factors such as climate, species interaction and harvesting pressure. However, additional complexity can arise if fishing increases the sensitivity to environmental variability. To predict the effects of fisheries and climate on marine populations, there is a need for improved understanding of how they affect...

Abstract:: Soil moisture is an essential climate variable influencing land–atmosphere interactions, an essential hydrologic variable impacting rainfall–runoff processes, an essential ecological variable regulating net ecosystem exchange, and an essential agricultural variable constraining food security. Large-scale soil moisture monitoring has advanced in recent years, creating opportunities to transform scientific understanding of soil...

Seamount subduction and earthquakes

Creator:: Watts, Anthony B., Koppers, Anthony A. P., and Robinson, David P.
Abstract:: Seamounts are ubiquitous features of the seafloor that form part of the fabric of oceanic crust. When a seamount enters a subduction zone, it has a major affect on forearc morphology, the uplift history of the island arc, and the structure of the downgoing slab. It is not known, however,...

A Polish Jew on the Florida Frontier and in Occupied Tennessee: Excerpts from the Memoirs of Max White

Creator:: Sapon-White, Richard
Abstract:: In the late 1850s, few young Jews, recently arrived in the United States from Poland, chose to live in Florida. Fortunately, one who did, Max White, wrote down his memoirs of those years, leaving us a remarkable, very personal account of life on the Florida frontier as well as a...

The Effect of Rainfall on the Surface Layer during a Westerly Wind Burst in the Western Equatorial Pacific

Creator:: Wijesekera, H. W., Paulson, C. A., and Huyer, A.
Abstract:: Measurements of a fresh surface anomaly (fresh lens) produced by rainfall during a westerly wind burst have been analyzed. The measurements were made in December 1992 as part of the Coupled Ocean–Atmosphere Response Experiment in the western equatorial Pacific (2°S, 156°E). Measurements included radar estimates of rainfall, upper-ocean temperature (T),...

Review of processing and analysis methods for DNA methylation array data

Creator:: Wilhelm-Benartzi, Charlotte S., Koestler, Devin C., Karagas, Margaret R., Flanagan, James M., Christensen, Brock C., Kelsey, Karl T., Marsit, Carmen J., Houseman, E. Andres, and Brown, Robert
Abstract:: The promise of epigenome-wide association studies (EWAS) and cancer specific somatic changes in improving our understanding of cancer coupled with the decreasing cost and increasing coverage of DNA methylation microarrays, has brought about a surge in the use of these technologies. Here, we aim to provide both a review of...

Introducing a sensor to measure budburst and its environmental drivers

Creator:: Kleinknecht, George J., Lintz, Heather E., Kruger, Anton, Niemeier, James J., Salino-Hugg, Michael J., Thomas, Christoph K., Still, Christopher J., and Kim, Youngil
Abstract:: Budburst is a key adaptive trait that can help us understand how plants respond to a changing climate from the molecular to landscape scale. Despite this, acquisition of budburst data is constrained by a lack of information at the plant scale on the environmental stimuli associated with the release of...
