Populations of threatened species, especially predators at the top of the food chain, may be affected by anthropic pressures. The endangered western population of European mink Mustela lutreola has shown a large decline over 50% of its natural range. M. lutreola disappeared from northwestern France between 1984 and 1997, and the decline was associated with an increase in mustelid trapping, chan...

The Paper presents an accounts of wild edible food plants used by shan tribe of Assam. The shan tribe of Assam is Sino-Tibetan race of Mongoloid stock whose ancestors migrated from South -west china. They depend upon forest products for their day to day needs, i.e, food, fodder and shelter etc. Their food include leaves, tubers, bulbs, rhizomes, flowers fruits and seeds of various wild plants s...

The incorporation of heavy metals contained in soils into the food chain is mediated by plants. Plants show varying abilities to take up and accumulate these elements during vegetative growth. In this study, changes content, rate uptake, accumulation, translocation six stages development pea plants were determined. field experiments, two cultivars cultivated consecutive growing seasons. harvest...

The use of constructed wetlands for water pollution control has a long standing tradition in urban, peri-urban, rural, agricultural and mining environments. The capacity of wetland plants to take up nutrients and to filter organic matter has been widely discussed and presented in diverse fora and published in hundreds of articles. In an ever increasingly complex global world, constructed wetlan...

At the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University Agriculture, Technology And Sciences, Prayagraj (U.P.), India, a field experiment was carried out during Harvest season 2022. To investigate how spacing and nitrogen affect sorghum growth fodder production (Sorghum bicolor L.). The treatments include at rates 60, 80, 100 kg/ha, spaced 35...

abstract to optimal use of available water, irrigation scheduling is important to over scarcity of water resources in arid and semi-arid area. in this research to estimate of maximum allowable deficit (or: management allowed depletion) and irrigation scheduling of fodder mays based on canopy-air temperature difference, a field study was conducted in agricultural faculty of karaj. the lower limi...

In this introductory paper for the Theme Issue on green tribology, we discuss the concept of green tribology and its relation to other areas of tribology as well as other 'green' disciplines, namely, green engineering and green chemistry. We formulate the 12 principles of green tribology: the minimization of (i) friction and (ii) wear, (iii) the reduction or complete elimination of lubrication,...

A unicellular blue-green alga, Agmenellum quadruplicatum, and a filamentous blue-green alga, Lyngbya lagerheimíi, were grown heterotrophically in dim light with glucose as major source of carbon and possibly energy. The dim-light conditions did not support autotrophic growth. The two blue-green algae appeared to have the same metabolic block, namely an incomplete tricarboxylic acid cycle, as ha...
