Marine Ecology: Gelatinous Bells May Ring Change in Marine Ecosystems
Gelatinous plankton are critical components of marine ecosystems. Recent studies are providing evidence of increased population outbursts of such species. Jellyfish seem to respond when an ecosystem is over-fished, and their ecology is under-researched.
متن کاملEutrophication of freshwater and marine ecosystems
Initial understanding of the links between nutrients and aquatic productivity originated in Europe in the early 1900s, and our knowledge base has expanded greatly during the past 40 yr. This explosion of eutrophication-related research has made it unequivocally clear that a comprehensive strategy to prevent excessive amounts of nitrogen and phosphorus from entering our waterways is needed to pr...
متن کاملParadigmatic and Inflectional Change: Some Theoretical Lessons
Several paradigm-based morphological changes in Greek and Latin are presented, including a persistent and recurring type of change involving the reshaping of inflectional endings based on other endings, that provide evidence first for the existence of paradigms and then for their internal structure. These considerations lead to an exploration of the relevance of various theoretical constructs a...
متن کاملReducing Phosphorus to Curb Lake Eutrophication is a Success.
As human populations increase and land-use intensifies, toxic and unsightly nuisance blooms of algae are becoming larger and more frequent in freshwater lakes. In most cases, the blooms are predominantly blue-green algae (Cyanobacteria), which are favored by low ratios of nitrogen to phosphorus. In the past half century, aquatic scientists have devoted much effort to understanding the causes of...
متن کاملEutrophication of freshwater and coastal marine ecosystems: a global problem.
GOAL, SCOPE AND BACKGROUND Humans now strongly influence almost every major aquatic ecosystem, and their activities have dramatically altered the fluxes of growth-limiting nutrients from the landscape to receiving waters. Unfortunately, these nutrient inputs have had profound negative effects upon the quality of surface waters worldwide. This review examines how eutrophication influences the bi...
