"This study examines the relative contribution of algae and vascular plant litter to the food chains of freshwater marshes. Twelve enclosures (5 m diam.) were deployed in a nutrient-poor marsh of the Interlake region of Manitoba. Algae levels in six of the enclosures were increased by fertilizing the water column. In addition, the hardstem bulrush (Scirpus lacustris glaucus (Sm.) Hartm) litter present was replaced with a non-nutritive artificial substrate in half of the fertilized and unfertilized enclosures. Fertilization did not affect the dry weight loss of bulrush litter, but N and P concentrations were higher in the decomposing litter of the fertilized treatments. Dominant taxa of nektonic herbivores-detritivores responded to fertilization but were not affected by the replacement of plant litter by a non-nutritive substrate. Epiphytic herbivores-detritivores responded to changes in both detritus and algal food sources. Fertilization resulted in early peaks of emergence for the Chironominae, Tanypodinae and Orthocladiinae. Emergence data late in the study period suggest that the importance of litter as a food source may increase as decomposition progresses." --

Bioaccumulation And Food Chain Analysis For Evaluating Ecological Risks In Terrestrial And Wetland Habitats written by M. Bollman and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 1998 with Ecological risk assessment categories.
As part of the ecological risk assessment process for terrestrial and wetland habitats, the evaluation of bioaccumulative chemicals of concern (BCCs) is frequently pursued through food-chain analysis with a subsequent comparison of daily doses to benchmark toxicity reference values, when available. Food-chain analysis has frequently been applied to the analysis of exposure to BCCs identified as chemicals of potential ecological concern (COPECs) in the ecological risk assessment process. Here, designed studies focused on wetland food-chains such as "hydric soil -> soil macroinvertebrate -> amphibian" and terrestrial food-chains such as "soil -> plant -> small mammal" illustrate an approach for the derivation and validation of trophic transfer factors for metals considered as COPECs such as cadmium, chromium, copper, lead, and zinc. The results clearly indicate that the transfer of chemicals between trophic levels is critical in the bioaccumulation process in wetland and terrestrial food-chains and is influenced by numerous interacting abiotic and biotic factors, including physicochemical properties of soil, and the role, if any, that the metal has in the receptor as a required trace element.

Nature sure is amazing! Plants produce their own food and they feed animals too. Animals, in turn, nourish the soil when they die. This process is called the food chain, and you will read about in the pages of this book. Grab a copy and start reading this book today.

Wetlands are complex ecosystems necessary for the health of our planet. In recent years, governments and environmental organizations have worked to protect these habitats and the organisms that can only thrive within their unique ecosystems. This enlightening volume takes readers into marshy wetlands, introducing them to high-interest animals and plants such as hulking hippos and the carnivorous Venus flytrap. Each stimulating chapter contains a flowchart that highlights key earth science concepts, including life cycles and food chains. Breathtaking photographs of wildlife and an accessible narrative make this book a memorable journey into a critical ecosystem.
