Recognition of desertification criteria and indices and determining the most effective factors on it are the first steps for logical planning to combat desertification. In this study, the sensitivity of the Jaz-Murian region to desertification was evaluated using IMDPA model which is one of the desertification assessment methods in arid and semi-arid regions, on the basis of geology-geomorpholo...
The KIDS model (Kielstau Discharge Simulation model) is a simple rainfall-runoff model developed originally for the Kielstau catchment. To extend its range of application we applied it to a completely different catchment, the XitaoXi catchment in China. Kielstau is a small (51 km2) lowland basin in Northern Germany, with large proportion of wetland area. And XitaoXi is a mesoscale (2271 km2) mo...
While many studies have explored how agriculture changes when population density rises, this paper examines actions farmers may take to control whether population density rises. Using information from ethnographic fieldwork, colonial archives, and air photography, two agricultural groups migrating into an agricultural frontier in the Nigerian savanna are compared. Population density in Kofyar c...
Field trials were conducted in late April to early May of 1995 and 1996 in central Israel to assess the potential for controlling rabies in red foxes (Vulpes vulpes) and golden jackals (Canis aureus) by using vaccine-laden baits. Of the bait types which were field tested, polymer fish meal baits were selected as the most suitable for both species. Fish meal baits containing tetracycline hydroch...
The potential for ingestion of plastic particles by open ocean filter feeders was assessed by measuring the relative abundance and mass of neustonic plastic and zooplankton in surface waters under the central atmospheric high-pressure cells of the North Pacific Ocean. Neuston samples were collected at 11 random sites, using a manta trawl lined with 333 u mesh. The abundance and mass of neustoni...

Construction of the Three Gorges Dam across the Yangtze River will substantially change the ecology of the Dongting Lake in southern China. In addition, the Chinese Central and Hunan Provinces' governmental authorities have instigated a Return Land to Lake Program that will extend the Dongting Lake surface area from the current 2,681 km2 to 4,350 km2. The previous construction of embankments an...
INTRODUCTION Located in the central Pacific between 4° and 14°north latitude and 160° and 173° east longitude, the Marshall Islands consist of two nearly parallel groups (the Ratak or Sunrise and the Ralik or Sunset Chains) of twenty-nine atolls and five table reefs, totalling 181 km2 of land and 10,455 km2 of lagoon area. Together these two chains extend about 1,130 km north to south and appro...
