human t-cell lymphotropic virus (htlv) types 1 and 2 belong to the oncorna group of retroviridae, a large family of viruses, grouped initially by pathogenic features, but later revised on the basis of genome structure and nucleotide sequence. htlv-i was the first discovered human retrovirus to be associated with a malignancy in 1980. the malignancy, first described by uchiyama and co-workers in...

Understanding the relationships between species, their environment, and factors that determine their distribution and abundance has historically been a goal of ecological theory (MacArthur, 1972; Guisan & Zimmermann, 2000). The topic continues to be pertinent, as ongoing environmental change is likely to alter species ranges and shift their patterns of habitat ARC Centre of Excellence for Coral...

iron oxide minerals in soils provide valuable insights into pedogenic processes. a wealth of such information has been obtained by rock magnetic investigations on temperate soils but similar studies on tropical soils are rare. here, we report rock magnetic data on pristine soil profiles and surficial soils from five catchments in the tropical southern india and throw light on the pedogenic pro...

effects of neglecting climatic patterns in buildings are more intense in severe climates such as tropical. it isresulting an excessive consumption of fossil fuels and consequently environmental pollutions in and after modern era. the objective of this research is to find climate-oriented intentions and solutions in tropical areas and compare them with dezful and bandar-e-lenge vernacular houses...

the plankton and semi-plankton samples examined from mizoram state of northeast india (nei) revealed speciose and diverse rotifera assemblage including a total richness (s) of 162 species belonging to 19 families and 35 genera. the reports of six species new to india, four species new to nei and 76 new records to mizoram merit biodiversity interest. the occurrence of one australasian, one orien...

Forest conversion for agriculture expansion is the most salient signature of human occupation of the earth's land surface. Although population growth and deforestation are significantly associated at the global and regional scales, evidence for population links to deforestation at micro-scales-where people are actually clearing0020forests-is scant. Much of the planet's forest elimination is pro...

We examined the number of tropical cyclones and cyclone days as well as tropical cyclone intensity over the past 35 years, in an environment of increasing sea surface temperature. A large increase was seen in the number and proportion of hurricanes reaching categories 4 and 5. The largest increase occurred in the North Pacific, Indian, and Southwest Pacific Oceans, and the smallest percentage i...
