Identification of priority areas is a fundamental goal in conservation biology. Because of a lack of detailed information about species distributions, conservation targets in the Zhoushan Archipelago (China) were established on the basis of a species-area-habitat relationship (choros model) combined with an environmental cluster analysis (ECA). An environmental-distinctness index was introduced to rank areas in the dendrogram obtained with the ECA. To reduce the effects of spatial autocorrelation, the ECA was performed considering spatial constraints. To test the validity of the proposed index, a principal component analysis-based environmental diversity approach was also performed. The priority set of islands obtained...

This point shapefile approximates locations within 20 km of the North Pacific Coastline, as defined by the "World Country Boundaries (Generalized)" shapefile distributed by ESRI as part of their Data & Maps data series. They are based on raster data at 4 km resolution. Therefore there are between 3-5 points extending out from each location along the shoreline (at 4 km intervals).

This dataset includes stable carbon and nitrogen isotope values for the inner tail retrices of three subspecies of barn swallow (Hirundo rustica rustica, H. r. tytleri, and H. r. gutturalis). Sampling was conducted in Russia (summer 2013), China (summer 2014), Mongolia (summer 2014), Japan (summer 2014), and western China (summer 2015) using mist nets. Stable carbon and nitrogen isotope data are useful proxies for diet and at broad spatial scales have the potential to constrain geographic distributions at the sub-population level. These data were used in tandem with molecular genetics to explore the extent to which a migratory divide explains the strength of reproductive isolation. There are two files in this dataset:...
Bottom simulating reflections (BSRs) are seismic features that are imaged in marine sediments using high-energy, impulsive seismic sources such as air guns or generator-injector guns. BSRs often cut across sediment stratigraphy and are interpreted as marking the deepest depth at which gas hydrate can exist. Gas hydrate is a naturally occurring and widely distributed frozen form of water and gas (usually methane) stable at low temperatures (up to about 25 degrees Celsius [°C]) and intermediate pressures (those that usually correspond to greater than 500 meters water depth). BSRs have been mapped in all the world’s oceans, in inland seas (such as the Black Sea), and in Lake Baikal in Russia. This data release consists...

This paper evaluates coal, petroleum, natural gas, nuclear energy and renewable energy resources as energy alternatives for China through use of a hierarchical decision model. The results indicate that although coal is still the major preferred energy alternative, it is followed closely by renewable energy. The sensitivity analysis indicates that the most critical criterion for energy selection is the current energy infrastructure. A hierarchical decision model is used, and expert judgments are quantified, to evaluate the alternatives. Criteria used for the evaluations are availability, current energy infrastructure, price, safety, environmental impacts and social impacts.
The uptake of nitrous oxide (N2O) occurs at the surface of the earth both in terrestrial and aquatic systems. This uptake is usually neglected in N2O budget studies. In this article, we discuss the likeliness of N2O uptake in different systems. These systems include soils as well as groundwater systems, riparian zones and surface waters. We address the possible consequences of ignoring surface sinks for N2O in global budgets as well as in national emission inventories. Our estimated surface sink is relatively small compared to the estimates of the present-day global emissions. Neglecting a possible surface sink of N2O may, therefore, not have major consequences for atmospheric budget studies on the global scale....

For the globalized world economy with intensive international trade, an overview of energy consumption is presented by an embodied energy analysis to track both direct and indirect energy uses based on a systems input–output simulation. In 2004, the total amounts of energy embodied in household consumption, government consumption, and investment are 7749, 874, and 2009 Mtoe (million tons of oil equivalent), respectively. The United States is shown as the world’s biggest embodied energy importer (683 Mtoe) and embodied energy surplus receiver (290 Mtoe), in contrast to China as the biggest exporter (662 Mtoe) and deficit receiver (274 Mtoe). Energy embodied in consumption per capita varies from 0.05 (Uganda) to 19.54...

Non-CO2 greenhouse gases, included in the Kyoto Protocol, are methane (CH4), nitrous oxide (N2O), hexafluorocarbons (HFC), perfluorinated compounds (PFC) and sulphur hexafluoride (SF6). Together they account for about 25% of the present global greenhouse gas emissions. Reductions in emissions of these gases have occurred in the industrialised countries, and they contribute to the efforts to reach the target of 5% greenhouse gas emission reduction as agreed in the Kyoto Protocol for these countries. Globally however, greenhouse gas emissions continue to increase as do the concentrations of these gases in the atmosphere. The relation between emissions and concentrations is not clear for all non-CO2 greenhouse gases....

The Sea Surface Temperature (SST) data of the nearshore region of the North Pacific show temperature ranges in degrees C using points whose locations correspond to the centroids of AVHRR Pathfinder version 5 monthly, global, 4 km data set (PFSST V50). The pathfinder rasters are available from the Physical Oceanography Distributed Active Archive Center (PO.DAAC), hosted by NASA JPL. The data points in this dataset lie within a 20 km buffer from the GSHHS (Global Self-consistent, Hierarchical, High-resolution Shoreline) coastline. The GSHHS vector data are available from the National Geophysical Data Center (NGDC). Furthermore, each point in the SST dataset is categorized by the ecoregion in which it is located. This...
Emergence of avian influenza viruses with high lethality to humans, such as the currently circulating highly pathogenic A(H5N1) and A(H7N9) cause serious concern for the global economic and public health sectors. To improve our understanding of the spatial and temporal trends in transmission risk we developed a model that predicts hotspots of novel virus emergence between domestic and wild birds and incorporates H5N1 risk factors. Models were produced at 30 km spatial resolution across two temporal seasons. Files are named using a TransmisisonDirection_Season_DataType format such that Transmission direction can end in a (poultry to waterfowl) or b (waterfowl to poultry), Season can be breeding (br) or wintering...
