climate change has direct and indirect consequences on crop production and food security. agriculture and cropproduction is one of the factors which depend on the weather conditions and it provides the human requirements inmany aspects. the objective of this study is to assess the impacts of future climatic change on irrigated rice yieldusing the ceres-rice model in the southern coast of caspia...

Background: The objective of this study was to determine the relationship between soil environmental factors and halophyte distribution in the west coast of South Korea. Soils of our study sites were categorized into two groups: salt marsh and estuary marsh. Results: Salinity was higher in the salt marsh group than that in the estuary marsh group. However, total nitrogen, silt, and clay content...

New shear wave splitting measurements made from stations onshore and offshore the South Island of New Zealand show a zone of anisotropy 100–200km wide. Measurements in central South Island and up to approximately 100 km offshore from the west coast yield orientations of the fast quasi-shear wave nearly parallel to relative plate motion, with increased obliquity to this orientation observed fart...

Although predispersal seed predation by insects is common, no test exists of its effect on plant recruitment. This study examines seed predation in the population dynamics of a native, temperate shrub, Haplopappus squarrosus H. and A. (Asteraceae), over an elevational gradient in the coastal sage scrub vegetation of San Diego County, California USA. Frequency and abundance of H. squarrosus incr...

upwelling areas in the ocean are important places for fishing as nutrients can be transported from deeper area to the near surface region. in this study, the upwelling in the eastern coastal area of the caspian sea for 2004 was studied using coherens, a three-dimensional ocean model. in order to simulate the circulation in the caspian sea, the gridded fields were chosen as 0.046 × 0.046 degrees...

Indothais blanfordi (Melvill, 1893), a muricid gastropod is being reported for the first time from Machilipatnam (16o 8′ 42.82′′ N and 81o 10′ 41.83′′ E) in Andhra Pradesh State situated on the northern east coast of India. This species was earlier recorded from Kalpakkam on the southern east coast, but not brought to light as first record to the east coast of India. Nevertheless, its occurrenc...

Ambient concentrations of eight predominantly anthropogenic halocarbons were measured via in situ gas chromatography in California's South Coast air basin for both summer and fall during the 2005 Study of Organic Aerosols at Riverside (SOAR). Ongoing emissions of the banned halocarbons methylchloroform and CFC-11 were observed in the South Coast air basin, whereas CFC-113 emissions have effecti...

Echinoderm diversity was studied from Mudasal Odai (Lat.11°29'N; Long. 79°46' E) and Nagapattinam (Lat. 10° 46' N; Long. 79° 59' E) coast of Tamil Nadu, south east India. We recorded 14 species, 11 genera, 8 families, 5 orders and 3 classes in Mudasal Odai and 11 species, 8 genera, 6 families, 5 orders and 3 classes in Nagapattinam coast. The most diverse families are Temnopleuridae (4 species ...

Biogeographical, physiological, and paleoecological evidence suggests that the coast redwood [Sequoia sempervirens (D. Don) Endl.] is closely associated with the presence of summer marine fog along the Pacific coast of California. Here we present a novel record of summer fog frequency in the coast redwood region upon the basis of direct hourly measurements of cloud ceiling heights from 1951 to ...
