Since the 1970s, acid rain has remained in the public spotlight in both Europe and the United States and recently has emerged as an important problem in other regions such as Southeast Asia. To reveal responses of Masson Pine to acid rain during a long time series in central China, we used the interpolation dataset of acid rain and the Global Inventory Modeling and Mapping Studies (GIMMS) norma...

Increases in drought-induced tree mortality are being observed in tropical rain forests worldwide and are also likely to affect the geographical distribution of tropical vegetation. However, the mechanisms underlying the drought vulnerability and environmental distribution of tropical species have been little studied. We measured vulnerability to xylem embolism (P50 ) of 13 woody species endemi...

Submit Manuscript | http://medcraveonline.com as Ceylon, together with the Western Ghats of the Peninsular India is recognized as one of the 34 global hot spots for biological diversity [2]. Sri Lanka, one of the pristine tropical islands located between latitudes 5° 55’ and 9° 51’ N and longitudes 79° 41’ and 81° 54’ E in the Indian Ocean near to the southern tip of the Coromandel Coast of the...

For sites located in different climatic regions, we estimated the relationship between annual average probability distributionof exceeding a fixed rain attenuation, and carrier frequency range 16 to 100 GHz, zenith paths of GeoSurf satellite constellations. In these constellations attenuation is independent altitude number satellites. Rain iss calculated with Synthetic Storm Technique, reliable...

We establish intra-individual and inter-annual variability in European badger (Meles meles) autumnal nightly activity in relation to fine-scale climatic variables, using tri-axial accelerometry. This contributes further to understanding of causality in the established interaction between weather conditions and population dynamics in this species. Modelling found that measures of daylight, rain/...

During 1984-2000, canopy tree growth in old-growth tropical rain forest at La Selva, Costa Rica, varied >2-fold among years. The trees' annual diameter increments in this 16-yr period were negatively correlated with annual means of daily minimum temperatures. The tree growth variations also negatively covaried with the net carbon exchange of the terrestrial tropics as a whole, as inferred from ...

When planning the link budget for millimetre and sub-millimetre wave telecommunications links, the attenuation by atmospheric gasses is taken into account. However, at millimetric frequencies above 50 GHz, it may become necessary to account for the temporal variations in absorption when calculating fade margins. Attenuation due to atmospheric absorption varies with temperature, barometric press...

Soil nitrate (NO3) tests are an integral part of nutrient management in annual crops. They help growers make field-specific nitrogen (N) fertilization decisions, use N more efficiently and, if necessary, comply with California’s Irrigated Lands Regulatory Program, which requires an N management plan and an estimate of soil NO3 from most growers. As NO3 is easily leached into deeper soil layers ...

Soil inventories of anthropogenic radionuclides were investigated in altitudinal transects in 2 French regions, Savoie and Montagne Noire. Rain was negligible in these 2 areas the days after the Chernobyl accident. Thus anthropogenic radionuclides are coming hypothetically only from Global Fallout following Atmospheric Nuclear Weapon Tests. This is confirmed by the isotopic signatures ((238)Pu/...

[1] The mass change of South America (SA) continent measured by the Gravity Recovery and Climate Experiment (GRACE) imposes a constraint on the uncertainties in estimating the annual variation of rainfall measured by Tropical Rain Measuring Mission (TRMM) and ocean moisture influx derived from QuikSCAT data. The approximate balance of the mass change rate with the moisture influx less climatolo...
