The Morinaceae (Dipsacales) contains 13 species placed in Acanthocalyx, Cryptothladia or Morina, and is distributed from the mountains of southeastern Europe through the Himalayas to the Qinghai-Tibetan Plateau, mainly in alpine habitats. Sequence data from two chloroplast regions (the trnK intron and the trnL-F region) and the internal transcribed spacer (ITS) region of nuclear ribosomal DNA w...

The 26 December 2004 Indian Ocean tsunami damaged severely most of the Gulf of Bengal’s coastal areas, but the coast of Bangladesh which stands at the edge of an extraordinarily extended continental shelf. This latter feature has been built through huge discharges of river sediments along the Brahmaputra and Ganges rivers. As a result of this enormous discharge, another interesting feature of t...

The present study deals with the detailed investigation on population dynamics of near-threatened catfish Ailia coila (Hamilton, 1822), which inhabits Brahmaputra River India and forms an important component freshwater inland fishery, providing nutritional financial security to local community. A total 1034 individuals were collected by weekly sampling from Uzanbazar Dhubri landing centres this...

Himalayan rivers have very unusual Sr characteristics and their budget cannot be achieved by simple mixing between silicate and carbonate even if carbonates are radiogenic. We present Sr, O, and C isotopic data from river and rain water, bedload and bedrock samples for the western and central Nepal Himalaya and Bangladesh, including the monsoon season. Central Himalayan rivers receive Sr from s...

Elevated arsenic concentrations in groundwater the Ganga–Brahmaputra–Meghna (GBM) river basin of India has created an alarming situation. Considering that is one largest consumers for a variety uses such as drinking, irrigation, and industry, it imperative to determine occurrence hazard sustainable management. The current study focused on evaluation Ganga employing Analytical Hierarchy Process ...

India is a place of variety with multicultural and multilingual dimensions. Various cultures are fused here the inner bond unity amid diversity. Thus, various religions like Buddhists, Hindus, Muslims, Jains, Sikhs coexisted friendship loyalty. regional barriers language or culture made unique in globe. It had history more than thousand years amalgamations different cultures. Every corner has s...

Using satellite measurements in microwave bands to retrieve precipitation over land requires proper discrimination of the weak rainfall signals from strong and highly variable background Earth surface emissions. Traditionally, land retrieval methods rely on a weak signal of rainfall scattering on high-frequency channels and make use of empirical thresholding and regression-based techniques. Bec...

Four species of Devario are recorded from Bangladesh: D. aequipinnatus, D. anomalus, D. coxi, new species, and D. devario. Devario aequipinnatus has a wide distribution in northern India and Bangladesh. Devario coxi, from southeastern Bangladesh near Cox's Bazar, differs from D. aequipinnatus in mtDNA (COI, p-distance 1.8%), colouration, proportional measurements, and meristics. The minor morph...

Sediment transfer from continents to oceans via rivers is one of the important processes regulating river-bank stabilization, soil formation, biogeochemical cycling of elements, crust evolution and many other earth-related processes. Due to changes in continental positions during the geologic past, water flow and sediment loads in rivers have also shown variations during different time periods....

Abstract Intermediate cities in Asia and Africa house more than 60% of the world’s urban population. More 54% people here face high levels water stress are increasingly vulnerable to water-related risks such as floods, limited access safe drinking pollution. These complex outcomes climate change, land use changes, governance failures, social inequities. This study examines co-evolution three re...
