The state of the world’s biodiversity appears worse than ever.
The Living Planet Index (LPI), which measures trends in thousands of vertebrate species populations, shows a decline of 52 per cent between 1970 and 2010 (Figure 2). In other words, the number of mammals, birds, reptiles, amphibians and fish across the globe is, on average, about half the size it was 40 years ago. This is a much bigger decrease than has been reported previously, as a result of a new methodology which aims to be more representative of global biodiversity.
Biodiversity is declining in both temperate and tropical regions, but the decline is greater in the tropics. The 6,569 populations of 1,606 species in the temperate LPI declined by 36 per cent from 1970 to 2010. The tropical LPI shows a 56 per cent reduction in 3,811 populations of 1,638 species over the same period. Latin America shows the most dramatic decline – a fall of 83 per cent. Habitat loss and degradation, and exploitation through hunting and fishing, are the primary causes of decline. Climate change is the next most common primary threat, and is likely to put more pressure on populations in the future.
WorldCat is a set of databases that together comprise the most comprehensive global network of data about library collections and services. WorldCat data is contributed, maintained and shared by libraries around the world. It is managed and enhanced by OCLC. Learn more »
http://elifesciences.org“This highly thought of open access journal promises a speed and ease of publishing unheard of in most traditional life science journals. Initial decisions on a manuscript are usually made within days. Post-review decisions are made within weeks. Most articles only go through a single round of revisions. For the reader, this means that the results you’re reading are hot off the lab bench. Best of all, unlike most scientific journals, which can cost upwards of $20 for a single article, the 842 (and counting) articles on this site are completely free. The eLIFE podcast is also available for easy download, online listening, or subscription. [CNH]“

Newswise — CHICAGO—In honor of World Food Day on October 16, the Institute of Food Technologists (IFT) is highlighting eight solutions for feeding the world from itsFutureFood 2050website. They include articles featuring Kofi Annan, M.S. Swaminathan, Sylvia Earle and more. Feel free to re-publish or share these links as part of your World Food Day coverage.
One hundred years after the extinction of the passenger pigeon, the nation’s top bird science and conservation groups have come together to publish The State of the Birds 2014—the most comprehensive review of long-term trend data for U.S. birds ever conducted.
NTIS is launching greater access to federally funded science & technology information and reports. Starting in October 2014, U.S. citizens will have free access to all electronically-available documents in the NTIS collection.
Currently there are more than 850,000 documents digitized for free public access. For the first time, Individuals will have the option to subscribe to the NTRL in order to benefit from the Premium features of the database, such as Digitization-on-Demand (NTRL Premium Individual). Premium Institutional subscribers (including corporations) will continue to have access to the more than 2.8 million records with a variety of enhanced features as listed in the chart below.
[Visited Jun’14] In 1994, the Army Corps of Engineers issued The National Drought Atlas, which is cataloged in only five libraries; it apparently never made it into the Federal Depository Library Program. A new online resource, the national Drought Risk Atlas, rectifies that oversight. The atlas has six sections: Home, Map Viewer, Data (viewer page), Methodology, About, and Help. Home provides introductory information about the atlas and explains the other sections. Map Viewer allows users to view drought status from 2000 to the present. The Data section allows users to select stations by name or interactively on a map and view data for that station over time. Many stations contain more than 100 years of data. Data can be displayed as a time series chart or table for a given decade. In addition, users can display data for each decade ranked from driest to wettest and warmest to coolest temperatures, along with ranked monthly precipitation and temperature records. The system also allows data retrieval for various indexes, including the Standardized Precipitation Index, Standardized Precipitation-Evapotranspiration Index, Palmer Drought Severity Index, and Self-calibrated Palmer Drought Severity Index.
There is a separate tabbed section for each index, which includes a description of the index and the option to select the period of interest. Data can be displayed as a time series chart, table, ranked table, or heat map plot, which shows whether a selected station was particularly wet or dry during the decade by color. Users can also download data for additional research. The Help section provides information on using the site. Many years ago, this type of weather data for selected locations was available in books published by Gale Research. This valuable site provides temperature and precipitation data and more for free. Summing Up: Highly recommended. All library collections.”
The Feynman Lectures on Physics are now available in their entirety online and for free. “First presented in the early 1960s at Caltech by the Nobel Prize-winning physicist Richard Feynman, the lectures were eventually turned into a book by Feynman, Robert B. Leighton, and Matthew Sands. The text went on to become arguably the most popular physics book ever written, selling more than 1.5 million copies in English, and getting translated into a dozen languages.”
“ Thomson Reuters and DataCite collaborate to expand discovery of research data-29 Aug 2014
The Intellectual Property & Science business of Thomson Reuters has announced a collaboration with DataCite, a global non-profit organization dedicated to enabling people to find, share, use, and cite data. The collaboration will promote the discovery of research data sets through the Data Citation Index, a single-point solution providing access to quality research data sets from multi-disciplinary repositories around the world.
This collaboration will connect the Data Citation Index to high quality research data from repositories worldwide that work with DataCite. This will ensure that the valuable content that has been made citable by DataCite is globally discoverable, properly attributed and reusable by other researchers. As part of the Web of Science – the premier scientific search and discovery platform and industry authority in science, social science, and arts & humanities citation indexes – inclusion within the Data Citation Index will also further DataCite’s mission of increasing acceptance of research data as citable contributions to the scholarly record.
Since creating the Data Citation Index, Thomson Reuters has worked closely with global industry leaders to expand the breadth of research discovery by capturing bibliographic records and cited references for digital research, as well as literature describing research which cites or uses the data, stewarding the accurate identification, attribution and measurement of this growing body of scholarship. The Data Citation Index allows users to gain a comprehensive view of the genesis of research projects and influence the future paths they may take, while minimizing the duplication of work and speeding the scientific research process to keep pace with the changing global research landscape. Through linked content and summary information, this data is displayed within the broader context of the scholarly research ecosystem, enabling users to gain perspective that otherwise would be lost if viewed in isolation.”
