Projections of a drier, warmer climate in the U.S. Southwest would complicate
management of the Colorado River system – yet these projections, often based on coarse
resolution global climate models, are quite uncertain. We present an approach to understanding
future Colorado River discharge based on land surface characterizations that map...
Three-dimensional chemical imaging of Fe–Cr alloys showing Fe-rich (α)/Cr-rich (α') phase separation is reported using atom probe tomography techniques. The extent of phase separation, i.e., amplitude and wavelength, has been quantitatively assessed using the Langer-Bar-on-Miller, proximity histogram, and autocorrelation function methods for two separate Fe–Cr alloys, designated 2101 and 2205....
Unusual collections of several euphausiid, chaetognath, and copepod species help elucidate
the effects of the strong 1997/1998 El Niño off the central Oregon, USA, coast. Furcilia of Nyctiphanes simplex, a euphausiid typically found only as far north as central California, were collected in bi-weekly nearshore samples between December 1997 and...
The construction of the first genetic map in autotetraploid blueberry has been made possible by the development of new SNP markers developed using genotyping by sequencing in a mapping population created from a cross between two key highbush blueberry cultivars, Draper × Jewel (Vaccinium corymbosum). The novel SNP markers were...
Endogenous small RNAs (endo-siRNAs) interact with Argonaute (AGO) proteins to mediate
sequence-specific regulation of diverse biological processes. Here, we combine deep-sequencing and
genetic approaches to explore the biogenesis and function of endo-siRNAs in C. elegans. We describe
conditional alleles of the dicer-related helicase, drh-3, that abrogate both RNA interference and...
1. Multidimensional trait frameworks are increasingly used to understand plant strategies for growth and survival. However, it is unclear if frameworks developed at a global level can be applied in local communities and how well these frameworks—based largely on plant morphological traits—align with plant physiology and response to stress.
2....
Historical ecology is becoming an important focus in conservation biology and offers a promising tool to help guide ecosystem management.
Here, we integrate data from multiple disciplines to illuminate the past, present, and future of biodiversity on California’s Channel Islands, an
archipelago that has undergone a wide range of land-use...
Drosophila suzukii Matsumura (spotted wing drosophila) has recently become a serious pest of a wide variety of fruit crops in the United States as well as in Europe, leading to substantial yearly crop losses. To enable basic and applied research of this important pest, we sequenced the D. suzukii genome...
Multibeam (1 m resolution) and side scan data collected from an autonomous underwater vehicle, and
lava samples, radiocarbon-dated sediment cores, and observations of flow contacts collected by remotely
operated vehicle were combined to reconstruct the geologic history and flow emplacement processes on
Axial Seamount’s summit and upper rift zones. The...
Coastlines have traditionally been engineered to maintain structural stability and to protect property from storm-related damage, but their ability to endure will be challenged over the next century. The use of vegetation to reduce erosion on ocean-facing mainland and barrier island shorelines – including the sand dunes and beaches on...
