Corridors that connect otherwise isolated habitats have often been proposed as a management strategy to mitigate negative effects of habitat fragmentation. Non-crop corridors may have the potential to enhance the connectivity for arthropod predators in cropland landscapes, especially for species that require multiple habitats, such as cavity-nesting wasps which use wooded habitat for nesting an...

GRASS GIS (Geographical Resources Analysis Support System) is a free, open source software and has been used for Remote Sensing (RS) and Geographic Information System (GIS) data analysis and visualization. Inside GRASS, different modules have been developed for processing satellite images. Currently, GRASS uses databases to handle large datasets and the performance and capabilities of GRASS for...

Grass carp (Ctenopharyngodon idellus) is one of the most important freshwater fish that is native to China, and crisp grass carp is a kind of high value-added fishes which have higher muscle firmness. To investigate biological functions and possible signal transduction pathways that address muscle firmness increase of crisp grass carp, microarray analysis of 14,900 transcripts was performed. Co...

The increasing rate of woody plant encroachment in grasslands or savannas remains a challenge to livestock farmers. The causes and control measures of woody plant encroachment are of common interest, especially where it negatively affects the objectives of an agricultural enterprise. The objectives of this study were to determine the effects of gut passage (goats, cattle), dung (nutrients), fir...

Two experiments were conducted to determine the effect of EM on the consumption, nutritive value and digestibility of elephant grass (Pennisetum purpureum Schum cv. napier) silages processed from wilted and fresh grasses. The first experiment was a feeding trial with sheep involving three treatments: fresh grass silage + 9% ground corn fed alone or inoculated with EM, and wilted grass silage in...

This research attempt to establish a grass cover change model based on cellular automata. It took the relationship between elevation, slope, aspect, settlement, road, water system and grass cover change as the foundation of the model, the dynamic progress of grass cover change was expressed by using cellular automata, the grass cover change model based on the basic geographical control conditio...

The turf grass Pennisetum clandestinum Hochst. (kikuyu grass) is one of the candidate plants for utilization and reclamation of salinized areas. The capability of kikuyu grass to grow under saline conditions was tested during 6 months, under various irrigation treatments (tap water control, 80-mM, 150-mM, 200-mM, 240mM NaCl). Plant biomass production was visibly affected only at NaCl concentrat...

Napier grass (Pennisetum purpureum), represents an interesting substrate for biogas production. The research project evaluated biogas potential production from dry anaerobic digestion of Napier grass using batch experiment. To enhance the biogas production from ensiled Napier grass, thermal and alkaline pre-treatments were performed in batch mode. Alkali hydrolysis of Napier grass was performed...

BACKGROUND Praziquantel (PZQ) is an effective pesticide against monogeneans. Its pharmacokinetics in fish may be affected by water environment and temperature. The present study was designed to compare the pharmacokinetics, tissue distribution, and elimination of PZQ in freshwater-acclimated grass carp and brackish water cultured grass carp. Plasma and tissue PZQ concentrations were determined ...
