Bacterial genetic fitness help regulate ocean carbon

The world’s oceans are dominated by microscopic organisms that power the Earth’s biogeochemical processes. These microbial ecosystems sustain life in the oceans by forming the basis of the ocean food web and balance the composition of our atmosphere – though scientists are just beginning to understand and study these ecosystems. A new research study led by the University of Georgia examines reproductive fitness of bacteria critical to the world-…

Niche dimensions of marine biotic powerhouse

Marine bacteria serve as regulators within and between ocean systems, processing about a quarter of all the photosynthesis on Earth. Because of their microscopic size and very short life span of a single day, learning what controls their activities, what nutrients they are trying to find, what molecules they grow on, and whether they interact with other microbes has been nearly impossible. In classical ecological terms, researchers don't have…

Burrowing animals control carbon cycling on the sea floor

Researchers from ETH Zurich and UGA show that the activity of burrowing worms, clams, and shrimp are the most important driver of the community structure of microorganisms in the Earth's biggest carbon sink: continental shelf sediments. The results were published this week in the Proceedings of the National Academy of Sciences: Sediments underlying the world’s oceans and shelf seas cover >70% of the Earth’s surface area. These sediments are…

Mapping important fish habitats along the Georgia coast

Beyond the barrier islands of coastal Georgia, the continental shelf extends gradually eastward for almost 80 miles to the Gulf Stream. This broad, sandy shelf largely does not provide the firm foundation needed for the development of reef communities to support recreational and commercial fish species including grouper, snapper, black sea bass and amberjack. “Natural and artificial reef habitats are important to Georgia fisheries because they…
