Covers the ecology of fresh, brackish, estuarine and marine environments. Presents timely reports on fundamental and applied research in the field and the laboratory. Provides a forum for aquatic ecologists to address and evaluate ecological issues related to processes and structures at different integration levels.Every living organism has an important role to play, and many are indispensable. Our aquatic wildlife are important sources of food, energy, jobs, atmospheric oxygen, buffers against new diseases, pests, and predators, and protection against food shortages and global climate change. Major threats to freshwater fishes and other freshwater biodiversity, include: habitat modification, fragmentation, and destruction; invasive species; overfishing; environmental pollution; forestry practise; and climate changeOceans provide at least a sixth of the animal protein people eat. Living oceans absorb carbon dioxide from the atmosphere and reduce climate change impacts. The diversity and productivity of the world's oceans is a vital interest for humankind. Our security, our economy, our very survival all require healthy oceans. Lack of ocean protection will not only accelerate climate change—it could impact our resilience to its impacts. Coral reefs, for example, provide coastal communities with important protection from storm surges. But they have already been pushed toward extinction by climate change, pollution and overfishing
