and storm flow from forest watersheds in the southern Appalachians according to a new study by U s. Forest Service scientists at the Coweeta Hydrologic Laboratory (Coweeta) located in Otto North carolina.
For this study Coweeta researchers used a paired watershed approach--one watershed with a major hemlock component in the riparian forest area the other reference watershed with very little--to determine the effects of hemlock mortality
Since hemlock woolly adelgid was detected first in 2003 all the eastern hemlock trees in both watersheds died resulting in a loss of 26 percent of forest basal area (that area occupied by tree trunks
and stems) in the riparian area of the first watershed compared to a 4 percent loss in the reference watershed riparian forest.
This latter finding suggests that riparian trees may play a disproportionally important role in regulating watershed processes than trees that aren't adjacent to the riparian zone.

and encircles three lagoons. Named after the American ship whose captain discovered it in 1802 Palmyra contains a 12-square-kilometer national wildlife refuge part of the larger Pacific Remote Islands Marine National monument established in 2009.
Manta rays are a highly mobile species that can travel across many different parts of the ocean.
Mccauley's team decided to focus on how mantas use Palmyra's lagoons. Lagoons are known to be ecologically important to a variety of mobile species including manta rays sharks turtles and dolphins.
We used high-resolution animal tracking tools to describe in as much detail as we could the ecology of the mantas
Using a novel combination of research tools the scientists examined how the manta rays use lagoons
and go from Palmyra's lagoons. Very heavily used by mobile animals as breeding grounds and as places to feed lagoons are highly sensitive to human disturbance.
Although there is no evidence that Palmyra ever supported permanent indigenous settlements its habitats were affected dramatically during WORLD WAR II
Lagoons are imperiled often very places so that was certainly part of our interest Mccauley said. Palmyra's lagoons and the mantas that use them are protected.
However lagoons elsewhere have been compromised. Fishing boat traffic and habitat degradation all may negatively affect mantas in less remote lagoons.
The big question Mccauley and his team wanted to answer is why manta rays congregate in this particular habitat.
It turns out it was at least partially because of the food. The researchers used stable isotope analysis a chemical assay of a tissue biopsy that provides an integrative view of what the animal ate in previous months.
They matched the chemical signature of the mantas to that of zooplankton collected in the lagoons verifying that this habitat serves as an important feeding ground.
Using mathematical modeling we determined that many of the manta rays we encountered took around 80 percent of their energy from lagoon plankton Mccauley said.
This discovery that lagoons can contribute such an important amount of food and energy to manta rays highlights the need to motivate management interventions in lagoons.
Other tools in the researchers'arsenal were high-resolution tracking which provided information about how the manta rays used the lagoon habitat over long and short periods of time;
an acoustic camera which logged patterns of the animals entrances and departures from the lagoons;
and photo identification/laser photogrammetry--making measurements from photographs--which provided insight into whether the manta rays were staying in this habitat for longer time periods by tracking their comings and goings.
Additional detailed information about how manta rays use ocean areas outside of lagoons will also be needed to better manage this at-risk species. Story Source:

and coastal development are more resilient to pressures from climate change according to the authors. Even if we could somehow make climate change disappear tomorrow these reefs would continue their decline says Jeremy Jackson lead author of the report and IUCN's senior advisor on coral reefs.
We must immediately address the grazing problem for the reefs to stand any chance of surviving future climate shifts.
The report also shows that some of the healthiest Caribbean coral reefs are those that harbour vigorous populations of grazing parrotfish.
These include the U s. Flower Garden Banks National Marine Sanctuary in the northern Gulf of mexico Bermuda and Bonaire all of

The Caribbean is home to 9%of the world's coral reefs which are one of the most diverse ecosystems on the planet.
Caribbean reefs spanning a total of 38 countries are vital to the region's economy.
The decline in corals started long before climate change began to affect reefs says Terry Hughes author of the 1994 study that predicted the current problems due to parrotfish removal.
These'resilient reefs'have strong local protections that are enforced strictly and double or triple the average coral cover of the 14%seen throughout the Caribbean.

Forest debris that drains into lakes is important to freshwater food chainsresearch shows forest debris that drains into lakes is an important contributor to freshwater food chains--bolstering fish diets to the extent that increased forest
Debris from forests that washes into freshwater lakes supplements the diets of microscopic zooplankton and the fish that feed off them--creating larger and stronger fish new research shows.
In fact the study was conducted at a Canadian lake chosen because it had suffered ecological disaster during the mid-20th century:
Despite moves to reduce environmental impact many areas of vegetation surrounding the lake are still in recovery.
This enabled scientists to study Yellow perch fish from different parts of a lake that has varying degrees of surrounding forest coverage.
Essentially the more forest around the edge of the lake the fatter the fish in that part of the lake were.
Scientists say that the young fish in lake areas with scant forest cover were much smaller
While plankton raised on algal carbon is more nutritious organic carbon from trees washed into lakes is a hugely important food source for freshwater fish bolstering their diet to ensure good size
The work was conducted at Daisy Lake on the outskirts of the industrial city of Sudbury in Ontario Canada.
The scientists studied eight different'watersheds'surrounding the lake: a given area across which all the moisture drains into a single stream.
When these fast-moving streams--full of detritus from forest foliage--hit the slow-moving lake the debris falls out of suspension
but the new research builds on previous work that showed they also feed on bacteria from forest matter drained into lakes.
Areas of Daisy Lake closest to the nickel smelt-works remain bare--dirt and rock instead of the once lush forest.
The young fish in these parts of the lake were considerably smaller due to less available food.
Now imagine that you manage acres of old-growth forest--or another natural resource like some fish in the ocean.

Ecology, super-sizedthe University of Wisconsin-Madison home of pioneering ecologists who studied lakes forests wetlands
But where UW-Madison's Edward Birge and Chancey Juday considered the founders of freshwater science once studied lakes one by one UW-Madison scientists are now leading several large-scale ecological investigations.
The university through its Trout Lake Station in Boulder Junction Wisconsin has played a pivotal role in the Global Lake Ecological Observatory Network (GLEON) an international network that has placed observation buoys at more than 100 lakes.
The 24/7 nature of data collection is essential says Tim Kratz director of Trout Lake and a GLEON founder.
One difficulty in studying lakes is that many organisms are very short-lived and the environment can change quickly.
Their records are being assembled to compare lakes of various sizes located in different geographic or social settings and climates Kratz says.
For example the project has discovered the release of greenhouse gases is controlled differently in large lakes versus small ones.

The research by hydrogeologists at The University of Texas at Austin which appears in the May 11 edition of the journal Nature Geoscience shows for the first time that virtually every drop of water coursing through 311000 miles (500000 kilometers) of waterways

While further research is needed this would make it unlikely that natural systems can accommodate the high levels of nitrates that have made their way from farmland and other sources into the river network's waterways.
