Water Pollution:Wastewater
Techniques for withdrawing, supplying, and disposing of water were already a part of early civilizations. Yet technologies for treating water and... -
Fundamentals
The term, pollution control technology, combines manufacturing and using “material systems”1) with natural resource protection — this includes not... -
A metabolism-based trophic index for comparing the ecological values of shallow-water sediment habitats
We determined fluxes of oxygen and nutrients between water and sediments at 21 sites primarily in Virginia and North Carolina estuaries, over the...

The relationships among man’s activities in watersheds and estuaries: A model of runoff effects on patterns of estuarine community metabolism
Activities of man in rivers and their watersheds have altered enormously the timing, magnitude, and nature of inputs of materials to estuaries....

Integrated Ecosystem Research in Northern Alaska, 1947–1994
Current research on human impacts in tundra ecosystems and landscapes builds upon a rich history of basic ecological studies carried out in Alaska... -
Functional Attributes of Angiosperm Hemiparasites and Their Hosts and Predictions of Possible Effects of Global Climate Change on Such Relationships
The 3,000 or so species and almost 200 genera of parasitic angiosperms of the world flora collectively represent an extraordinarily broad assemblage... -
Land-Water Interactions: The Influence of Terrestrial Diversity on Aquatic Ecosystems
As ecologists, we have learned much about the effects of species diversity on the biological aspects of communities. In an effort to expand our... -
Nutrition of Corals
Above it was mentioned that most scleractinian corals and more than half of the taxa of octocorals inhabiting coral reefs have algal symbionts in... -
Net system production in coastal waters as a function of eutrophication, seasonality and benthic macrofaunal abundance
Net system production ranged from 13% to 29% of apparent system production in enclosures modelling coastal marine waters. Net production was measured...

Evolution of Matter and Energy
Maybe during our time, at the end of the twentieth century or at the beginning of the next century, the old dream of natural sciences will become... -
Biogeochemical cycling constraints on stream ecosystem recovery
In systems where production is limited by the availability of a nutrient, nutrient input to and recycling within the system is related to the...

The significance of the biological sulfur cycle in rice production
Rice is one of the world’s most important food crops, forming nearly 20 percent of the world’s food grain production [226]. It is grown on 137 × 106... -
Ecological perspective on water quality goals
The central assumption of nonpoint source pollution control efforts in agricultural watersheds is that traditional erosion control programs are...
