This study describes changes in the trophic status of 12 lakes within Suwałki Landscape Park (SLP). All of the trophic classifications of the lakes were based on the trophic continuum division. Trophic status was determined by means of multiparameter indices using several diverse criteria. In this study, the assessment of the trophic status of lakes included water quality; abundance and biomass...

A method developed to evaluate the cumulative effect of wetland mosaics on water quality was applied to 33 lake watersheds in the seven-county region surrounding Minneapolis-St. Paul, Minnesota. A geographic information system (GIS) was used to record and measure landscape variables derived from aerial photos. Twenty-seven watershed land-use and land-cover variables were reduced to eight princi...

Algae react to changes in their environment, such as temperature, nutrients, etc. The uncertainty aquatic environments exacerbates several interacting pressures. As a result, lakes are vital society because they help mitigate flood risks. It maintains the natural equilibrium, allowing flora and fauna flourish. primary objective of this research is identify trophic state index, category, algal a...

Remote monitoring of trophic state for inland waters is a hotspot water quality studies worldwide. However, the complex optical properties limit potential algorithms. This research aims to develop an algorithm estimate in waters. First, turbid index was applied determination types on each pixel, and bodies are divided into two categories: algae-dominated (Type I) II). The algal biomass (ABI) th...

Exploited ecosystems are characterised by exports of secondary production from each fished trophic level that reduce the energy available for upper levels at ecosystem scale thus impinging on overall secondary productions. Depletion in secondary production with respect to the unfished state is here proposed as a proxy for quantifying ecosystem effects of fishing. Theoretical analysis of trophic...

The present paper is an attempt to test the applicability of the trophic state index (TRIX) for scaling the eutrophication along the Bulgarian Black Sea coastal zone in concert with a number of chemical and biological descriptors aimed at selection of relevant indicators of marine coastal area ecological quality. The following environmental parameters have been considered: t(o), salinity, nutri...
