Sources of Escherichia coli in a coastal waterway located in Ft. Lauderdale, Fla., were evaluated. The study consisted of an extensive program of field measurements designed to capture spatial and temporal variations in E. coli concentrations as well as experiments conducted under laboratory-controlled conditions. E. coli from environmental samples was enumerated by using a defined substrate te...
Polyploidy and symbiotic Epichloë fungal endophytes are common and heritable characteristics that can facilitate environmental range expansion in grasses. Here we examined geographic patterns of polyploidy and the frequency of fungal endophyte colonized plants in 29 Festuca rubra L. populations from eight geographic sites across latitudes from Spain to northernmost Finland and Greenland. Ploidy...
Eriocnema fulva Naudin is a perennial herb, endemic to Minas Gerais state, SE Brazil, found on humid, shaded rocky riverbanks in montane semideciduous seasonal forests. The species is threatened, but information regarding its biology is still lacking, although such information is fundamental to any management plan. We aimed to evaluate the reproductive system of Eriocnema fulva in the Jambreiro...
Blind, through, combined transverse dams are widely used as regulation structures to protect riverbanks and regulate river channels. Under the influence of these structures, a redistribution liquid solid runoff, including suspended sediments, occurs. This article aims develop method for forecasting mud silting vortex zone behind dam. The concept coefficients siltation in width, area, volume is ...
Abstract Riverbank is a buffer zone for the river ecosystem and surrounding land. The significant land use changes cover reduction in Merawu Watershed had put pressure on riverbank threatened protection function sustainability. Thus, this study aims to 1) identify riverbank’s ecological status, 2) its Protection Carrying Capacity (PCC), 3) determine indicative location of rehabilitation, 4) dev...
Abstract The purpose of this paper is to assess the failure mechanism riverbanks due stream flow experimentally and numerically avoid recurring landslides by identifying most dangerous place treating them a suitable method. experiments physical models were carried out study riverbank evaluation their stability in two cases: short-term condition long-term where three tested. Tigris River (Iraq) ...
In Indonesia, the Adiwiyata schools’ development program has implemented environmental education. These schools have a responsibility to preserve environment, especially around school grounds. One of elements conservation is Brantas watershed area which currently experiencing degradation due human activities. This study aimed explain how education in contributes students’ knowledge, and examine...

Increased agricultural use of tropical peatlands has negative environmental effects. Drainage leads to landscape-wide degradation and fire risks. Livelihood strategies in peatland ecosystems have traditionally focused on transitions from riverbanks forests. Riparian ‘Kaleka’ agroforests with more than 100 years history persist the Central Kalimantan (Indonesia), where large-scale open-field pro...
Abstract Sediment transport in rivers is an important and complex process. It very to know the nature quantities of sediments transported course achieve prudent water management. Due presence most projects on or near banks river study area, so there always a fear that these will be affected by processes erosion, transport, sedimentation among decision makers. Therefore, need develop our knowled...
