The purpose of this work was to investigate the sound environment of public parks using a soundscape study model that analyzes not only noise but also all the types of sound of a given area, as well as other environmental factors. To this end, acoustic measurements were made in the parks under study and interviews were held with their frequent visitors. Noise measurements were conducted in 55 p...
Purpose of wetland creation and restoration and expected results (protection vs. nourishment) Riparian ecosystems generally compose a minor proportion of surrounding areas, but typically are more structurally diverse and more productive in plant and animal biomass than adjacent upland areas. Riparian areas supply food, cover, and water (especially important in the arid regions) for a large dive...
We compared small mammal communities between riparian (stream corridor) and nearby upland habitats in a hardwood forest ecosystem on Fort A.P. Hill, Caroline County, Virginia. We used a combination of small-scale drift fence/pitfall trap arrays and snap traps to capture small mammals during April October 1998, with an additional winter sample in January 1999. We captured seven small mammal spec...
the science parks have important role in development of technology and are able to make economic growth of the countries. the purpose of this paper is the presentation of a fuzzy expert system (fis) as intelligent systems to evaluate the science and technology parks. one of the problems for evaluating science and technology parks is to have the high number of criteria and science parks which ah...
This work intends to examine if there are associations between fish species and the state of conservation of the riparian forest in the Corumbataí River Basin. Four main rivers were chosen for this study with three sites on each. Collections were carried out from March to June and from September to December 2001. Multivariate techniques were applied to determine the correlation between species ...
Riparian zones can provide a protective buffer between streams and adjacent land-based activities by removing nitrate from shallow groundwater flowing through them. Catchment-scale waterquality models are useful tools for predicting catchment behaviour under various climatic conditions and land-use scenarios. In this paper, we use the Riparian Nitrate Model (RNM) to investigate the potential ro...
2 Forest Advisor, University of California, Cooperative Extension, Eureka, California Abstract: Data on riparian community composition and environmental conditions were collected on over 20 streams in the Sierra Nevada as part of hydropower licensing studies. Over 1,000 samples were analyzed using two-way indicator species analysis (TWINSPAN), to determine riparian dominance types. Ordination t...
Science and technology parks, as one of the infrastructures of science-based economy, have played a specific role in the development of regional, local, and urban economy. The current study, aiming at helping the development of the function of such parks, utilizing data-driven conceptualization-theory method, one of the qualitative methods, analyzes and identifies effective contextual factors i...
A riparian buffer (also known as riparian vegetative filter strips, or buffer strips) is an area of vegetated land surrounding a waterbody, potentially capable of filtering non-point source pollution in runoff from adjacent lands. Main pollutants studied include sediment, nitrogen, phosphorus, bacteria, and pesticides. Although the literature suggests a general consensus about a riparian buffer...
A long-term study of four degraded streams in the upper Owens River watershed documented the recovery of riparian habitats and significant improvement in channel morphology in response to grazing strategies, recreation management, and pre-irrigation peak flows. Increased control of livestock distribution, timing of forage use and degree of forage utilization on and near stream banks was designe...
