Numerous leguminous species are used or have potential uses for timber production, pharmacological products, or land reclamation. Through N(2)-fixation, many leguminous trees contribute to the N-balance of tropical wetlands and rainforests. Therefore, studies of the N(2)-fixation ability of leguminous species appear to be crucial for the better use and conservation of these resources. The globa...

Part (I) of this study presented field and laboratory experimental data on soil characteristics and hydraulic parameters that are related to water infiltration in rice paddy fields. Part (II) includes a series of numerical simulations that are based on the in situ data, which three-dimensional finite element computer model for simulating density dependent flow and transport (FEMWATER) produced ...

Bangladesh suffered damage on accounts of the most catastrophic flood during the year of 1988, resulting in untold suffering to the people, crops were lost, lives were lost, infrastructures were damaged, and so on. The flood problem is therefore great important. The present study dealt by using MOS-1, MESSR data with other thematic maps to evaluate the affect and damage area in collaboration wi...

Flood becomes regular feature in riverrine Bangladesh. Every year, around 21 percent of land is flooded during monsoon season, however, in severe situation this figure shot up to more than 60 percent of total land. This paper is an attempt to analyze hydrological characteristics of two catastrophic events (1988 and 1998 flood) in the light of flood history in Bangladesh. The analysis demonstrat...

William J. Andrews, Jason R. Masoner, Oklahoma Water Science Center, U.S. Geological Survey The abandoned Picher mining district of northeastern Oklahoma was the largest source of lead and zinc in the world in the 1920s. After abandonment in the late 1960s, the district continued to be affected by severe environmental degradation, such as subsidence and metals such as cadmium and lead seeping f...

Habitat loss and fragmentation are the greatest threats to the endangered Florida panther (Puma concolor coryi). We developed a data-based habitat model and userfriendly interface so that land managers can objectively evaluate Florida panther habitat. We used a geographic information system (GIS) and the Mahalanobis distance statistic (D) to develop a model based on broad-scale landscape charac...

BACKGROUND Predicting habitats prone to favor disease transmission is challenging due to confounding information on habitats, reservoirs, and diseases. Comparative analysis, which aims at investigating ecological and evolutionary patterns among species, is a tool that may help. The emergence of zoonotic pathogens is a major health concern and is closely linked to habitat modifications by human ...
