Changes in the potential distribution of humid tropical forests on a warmer planet
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, Vol. 369. N° 1934. Zelazowski Przemyslaw; Malhi Yadvinder; Huntingford Chris; et al. - The Royal Society, 2011The future of tropical forests has become one of the iconic issues in climate-change science. A number of studies that have explored this subject have tended to focus on the output from one or a few climate models, which work at low spatial resolution, whereas society and conservation-relevant assessment of potential impacts requires a finer scale. This study focuses on the role of climate on the current and future distribution of humid tropical forests (HTFs).

in Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences > Vol. 369. N° 1934 (2011) . - p. 137-160The future of tropical forests has become one of the iconic issues in climate-change science. A number of studies that have explored this subject have tended to focus on the output from one or a few climate models, which work at low spatial resolution, whereas society and conservation-relevant assessment of potential impacts requires a finer scale. This study focuses on the role of climate on the current and future distribution of humid tropical forests (HTFs). We first characterize their contemporary climatological niche using annual rainfall and maximum climatological water stress, which also adequately describe the current distribution of other biomes within the tropics. As a first-order approximation of the potential extent of HTFs in future climate regimes defined by global warming of 2°C and 4°C, we investigate changes in the niche through a combination of climate-change anomaly patterns and higher resolution (5 km) maps of current climatology. The climate anomalies are derived using data from 17 coupled Atmosphere–Ocean General Circulation Models (AOGCMs) used in the Fourth Assessment of the Intergovernmental Panel for Climate Change. Our results confirm some risk of forest retreat, especially in eastern Amazonia, Central America and parts of Africa, but also indicate a potential for expansion in other regions, for example around the Congo Basin. The finer spatial scale enabled the depiction of potential resilient and vulnerable zones with practically useful detail. We further refine these estimates by considering the impact of new environmental regimes on plant water demand using the UK Met Office land-surface scheme (of the HadCM3 AOGCM). The CO2-related reduction in plant water demand lowers the risk of die-back and can lead to possible niche expansion in many regions. The analysis presented here focuses primarily on hydrological determinants of HTF extent. We conclude by discussing the role of other factors, notably the physiological effects of higher temperature.

Growth pattern of a common feather moss, Hylocomium splendens, from contrasting water regimes in a high Arctic tundra
Antarctic Record, Vol. 54, No. 2. Ueno Takeshi; Kanda Hiroshi - Scholarly and Academic Information Navigator (CiNii), 2010Hylocomium splendens, a widespread feather moss, is one of the major plant species found in high-Arctic tundra. It occupies a variety of habitats ranging from exposed dry ground to swampy areas. To clarify the effect of the water regime on the growth pattern of H. splendens, the shoot morphology of H. splendens growing in contrasting water regimes, i.e. hydric, mesic and xeric sites, was investigated using retrospective analyses of growth. The derived growth parameters for H. splendens differed considerably among the sites. The growing period at the hydric, mesic and xeric sites was 1 year, 2 ...

Further Study of Typhoon Tracks and the Low-Frequency (30-60 Days) Wind-Field Pattern at 850 hPa
Atmospheric and Oceanic Science Letters, Volume 3 Number 6. Tian Hua; Li Chong-Yin - Science Press, 2010The association of typhoon tracks over the western Pacific with the low-frequency wind-field pattern of atmospheric intraseasonal (30-60 days) oscillation at 850 hPa is further studied by using observational data analyses. Comparative analyses of the composite wind fields at 850 hPa, contrasting the atmospheric intraseasonal oscillation (ISO) with the original circulation, show that the typhoon tracks are closely related to the wind pattern of the ISO but are not obviously related to the original wind fields. Case studies of two typhoons in 2006 also show that the low-frequency wind-field patt ...

Polar Vortex Response to Pacific Ocean Warming and Its Additive Nonlinearity with the Indian Ocean
A previous modeling study about Pacific Ocean warming derived polar vortex response signals, by subtracting those in the Indian Ocean warming experiments from those in the Indo-Pacific. This approach questions the resemblance of such an indirectly derived response to one directly forced by Pacific Ocean warming. This is relevant to the additive nonlinearity of atmospheric responses to separated Indian and Pacific Ocean forcing. In the present study, an additional set of ensemble experiments are performed by prescribing isolated SST forcing in the tropical Pacific Ocean to address this issue. T ...

Regime Behavior in the Sea Surface Temperature-Cloud Radiative Forcing Relationships over the Pacific Cold Tongue Region
Atmospheric and Oceanic Science Letters, Volume 3 Number 5. Wu Chun-Qiang; Zhou Tian-Jun; De-Zheng Xiao-Li - Science Press, 2010Previous analyses on the estimates of water vapor and cloud-related feedbacks in the tropics usually use observations over the Earth Radiation Budget Experiment (ERBE) period (1985–89). To examine the sample dependence of previous estimates, the authors extend the analysis to two additional periods: 1990–94 and 1995–99. The results confirm our hypothesis, i.e., the values of the feedbacks depend on the period of data coverage. The differences in the feedbacks from cloud radiative forcings (CRFs) estimated from the three periods are particularly significant. Two possible causes for these differ ...

IUCN/NRDC Workshop to Identify Areas of Ecological and Biological Significance or Vulnerability in the Arctic Marine Environment : Workshop Report
Human activity is expanding in the Arctic marine environment, in part due to warming ocean temperatures and the dramatic loss of summer sea ice. New and expanding human uses include fishing, shipping and offshore oil and gas development. All have the potential to place major additional stress on ocean ecosystems which are already undergoing profound change related to warming, sea ice loss, and alterations in ocean chemistry.
Because activities conducted in one nation's waters can affect other parts of the region, effective management of some human uses in the Arctic marine environmen ...

Why monitor the Arctic Ocean? Services to society from a sustained ocean observing system
Bates Peter; Alverson Keith; Intergovernmental Oceanographic Commission (IOC); et al. - UNESCO, 2010Never has accurate information been more important, yet at
present we know very little about the Arctic Ocean. Critical physical processes are poorly understood, ecosystems remain unstudied and undiscovered, and indigenous voices go unheard. This lack of knowledge thwarts efforts to detect, predict or manage the interrelated physical, biological and social impacts of climate change, making sustainable development almost impossible. A coordinated observing system must therefore be
created for the Arctic Ocean and its coasts, to provide baseline data and ensure sustained monitor ...

The status and distribution of freshwater biodiversity in the Eastern Himalaya
IUCN, 2010Biodiversity within inland water ecosystems in the Eastern Himalaya region is both highly diverse and of great regional importance to livelihoods and economies. However, development activities are not always compatible with the conservation of this diversity, and the ecosystem requirements of biodiversity are frequently not considered in the development planning process. One of the main reasons cited for inadequate representation of biodiversity is a lack of readily available information on the status and distribution of inland water taxa. In response to this need for information, the IUCN Spe ...
