Several studies indicate that, during daylight hours, mangrove-lined shorelines can harbor high fish densities, with individuals presumably benefitting from reduced predation risk among the prop roots (e.g. Parrish 1989; Robertson & Blaber 1992; Laegdsgaard & Johnson 1995). Within mangrove shorelines, fish densities tend to be lower at night, as components of the assemblage disperse into adjace...

Interstitial water, faunal samples, and hydrogeological data were collected beneath a riffle on the Speed River, southern Ontario, Canada. The purpose was to identify the location and seasonal fluctuation of the hyporheic/groundwater interface and to examine several aspects of water mass chemical signatures and the dynamics of the interstitial fauna. Concentration discontinuities in several wat...

Ecotones are zones of gradual changes from an ecological system to another.Ecotones monitoring could be important to find out the reason for changes and limits. Inthis research satellite data were used to analyze the ecotone boundary in Fars steppicrangelands using IRS LISS III and Pan data of year 2006. The real vegetation map andecotones prepared through Geo-eye images from Google earth softw...

The impact of development on the ecological environment is a matter concern, especially in ecologically fragile agro-pastoral ecotone. ecotone northern Shaanxi (ANS) representative region China. agricultural use sand land (AUSL) an effective way to respond needs this region. AUSL will certainly have water yield services ANS, where resources are already scarce. In study, Integration Valuation Ec...
