Microbial indicators of aquatic ecosystem change: current applications to eutrophication studies.
Human encroachment on aquatic ecosystems is increasing at an unprecedented rate. The impacts of human pollution and habitat alteration are most evident and of greatest concern at the microbial level, where a bulk of production and nutrient cycling takes place. Aquatic ecosystems are additionally affected by natural perturbations, including droughts, storms, and floods, the frequency and extent ...
متن کاملDoes eutrophication-driven evolution change aquatic ecosystems?
Eutrophication increases primary production and changes the relative abundance, taxonomic composition and spatial distribution of primary producers within an aquatic ecosystem. The changes in composition and location of resources alter the distribution and flow of energy and biomass throughout the food web. Changes in productivity also alter the physico-chemical environment, which has further e...
متن کاملMicrobial Diversity of Aquatic Ecosystem and its Industrial Potential
Microbial diversity is an important constituent of an overall global biological diversity present in this planet. Microbial diversity that we observe today is the consequence of nearly 4 billion years of evolutionary change. Apart from several niches present in earth, the freshwater lakes are important habitats for diverse microbial communities. Freshwater and marine environments differ in many...
متن کاملClimate change effects on aquatic biota, ecosystem structure and function.
Climate change is projected to cause significant alterations to aquatic biogeochemical processes, (including carbon dynamics), aquatic food web structure, dynamics and biodiversity, primary and secondary production; and, affect the range, distribution and habitat quality/quantity of aquatic mammals and waterfowl. Projected enhanced permafrost thawing is very likely to increase nutrient, sedimen...
متن کاملClimate Change Uncouples Trophic Interactions in an Aquatic Ecosystem
The largest uncertainty in forecasting the effects of climate change on ecosystems is in understanding how it will affect the nature of interactions among species. Climate change may have unexpected consequences because different species show unique responses to changes in environmental temperatures. Here we show that increasingly warmer springs since 1962 have disrupted the trophic linkages be...
