2018 Ocean Science Meeting Presentations

Posted

The Ocean Sciences Meeting (OSM) has become an important venue for scientific exchange across a wide range of marine science disciplines, especially as human impacts on the oceans reach unprecedented levels. OSM, co-sponsored by the American Geophysical Union (AGU), the Association for the Sciences of Limnology and Oceanography (ASLO), and The Oceanography Society (TOS), will be held 11–16 February, in… Read more »

Why smaller oysters? Maybe not Native American shellfishing

Posted

Five thousand years ago, Native Americans lived and thrived on Georgia’s coast. Shellfishing, especially the Eastern oyster (Crassostrea virginica), was a significant cultural practice of these coastal Natives Americans. Today, Georgia’s coast is peppered with oyster shell deposits from long-term native American consumption. While studying archaeological shell deposits on Georgia’s coast, researchers with the Georgia Coastal… Read more »

At the 2017 AGU Fall Meeting, held at the New Orleans Ernest N. Morial Convention Center in New Orleans, Louisiana, from December 11-15, 2017, dozens of LTER researchers will present new results on a range of topics, from how ecosystems recover from droughts and hurricanes to what manufactured ice storms can reveal about how to prepare for winter’s worst. Links to the abstracts for over 100 LTER presentations at AGU 2017.

Foraging Flexibility of Two Shark Species

Posted

Sharks are top predators in marine ecosystems, so small changes in shark populations can ripple down and affect entire marine communities. Understanding how sharks adapt to ecosystem changes may help scientists predict how other marine life could react to a changing ocean. Researchers from the Florida Coastal Everglades (FCE) LTER investigated how juveniles of two similar… Read more »

Fire-driven Changes to Gap Regeneration

Arctic wildfire

Interior Alaska: black spruce and mosses as far as the eye can see. New research suggests that image may change dramatically over the next century. As the intensity of fires in interior Alaska increases, forest regrowth is shifting from spruce to deciduous species such as trembling aspen and Alaska paper birch. But intense fires also… Read more »

The landscaping culture behind ecological change

As a result of urbanization and globalization, residential ecosystems are increasingly homogeneous, with the potential to impact ecological dynamics at ever-expanding scales over the next 50 to 100 years. Despite this trend, researchers… Read more »

They are now being used to track alligators, the rulers of the swamp, to learn more about their movements between freshwater and marine environments. Once attached, the GPS and radio transmission devices can track the… Read more »

Winter Conditions Vital to Year-Round Lake Dynamics

Posted

This month’s Ecology Letters features the first global quantitative synthesis of under-ice lake ecology. In their analysis of 36 abiotic and biotic variables across 101 lakes, the authors issue a call to arms for more winter lake research—currently the focus of only 2% of freshwater publications. As the climate warms, they warn, temperate ecosystems are losing ice, and limnologists remain unsure what ecological processes are at stake. Though winter has long been understood as an inactive period, some data suggests that winter foodwebs and physical processes remain vigorous and that winter ecology can drive subsequent summer conditions.
