Land areas that are a priority for wildlife conservation provide relatively high levels of ecosystem services such as pollination, water purification, food production, and climate regulation, so safeguarding them is expected to benefit people. Assessing these benefits to populations in ways that are useful to decisionmakers who guide conservation efforts has, however, proved difficult.
A global analysis published in the January 2012 issue of BioScience by Will R. Turner of Conservation International and his colleagues breaks new ground by analyzing the flow of benefits from ecosystem services under a variety of socioeconomic assumptions and in greater spatial detail than previous studies. The analysis, which divides the globe into more than 58,000 hexagons, finds that over half the global value of ecosystem services benefitting the world's poorest people originates in areas that are a high priority for conservation. Moreover, the value of ecosystem services generated by the top quarter of biodiversity sites is more than triple the effective cost of conserving them.
If there were effective and equitable mechanisms to ensure that the beneficiaries of ecosystem services paid those responsible for stewarding them, Turner and his colleagues conclude, global benefits to poor communities would robustly increase by 50 percent, and the payments would amount to more than a dollar per person per day for about a third of the 1.1 billion people in the world living in dire poverty. The authors say their findings reinforce the idea that there is an important concordance between biodiversity, provision of ecosystem services, and poverty that policymakers could use in designing equitable payment schemes to address both poverty and loss of biodiversity.

BioScience, published monthly, is the journal of the American Institute of Biological Sciences (AIBS). BioScience publishes commentary and peer-reviewed articles covering a wide range of biological fields, with a focus on "Organisms from Molecules to the Environment." The journal has been published since 1964. AIBS is an umbrella organization for professional scientific societies and organizations that are involved with biology. It represents nearly 160 member societies and organizations.
The complete list of peer-reviewed articles in the December 2011 issue of BioScience is as follows:

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
