Ecological Mapping in Application to Aquatic Ecosystems Bioindication: Problems and Methods

Global ecological impacts of invasive species in aquatic ecosystems.

The introduction of invasive species, which often differ functionally from the components of the recipient community, generates ecological impacts that propagate along the food web. This review aims to determine how consistent the impacts of aquatic invasions are across taxa and habitats. To that end, we present a global meta-analysis from 151 publications (733 cases), covering a wide range of ...

Human effects on ecological connectivity in aquatic ecosystems: Integrating scientific approaches to support management and mitigation.

Understanding the drivers and implications of anthropogenic disturbance of ecological connectivity is a key concern for the conservation of biodiversity and ecosystem processes. Here, we review human activities that affect the movements and dispersal of aquatic organisms, including damming of rivers, river regulation, habitat loss and alteration, human-assisted dispersal of organisms and climat...

Helminthic Parasites as Heavy Metal Bioindicators in Aquatic Ecosystems

Abstract         Heavy metals have raised one of the most important problems in ecology and organisms life especially human being and animals. A variety of indicators including tissues of fish, birds and sediment have been used recently to measure the aquatic pollution with heavy metals. The aim of this study was to search the published articles in Iran a...
