Deep-sea benthic systems are notoriously difficult to sample. Even more than for other benthic systems, many
flows among biological groups cannot be directly measured, and data sets remain incomplete...
Submarine hydrocarbon seeps are geologically driven “hotspots” of increased biological activity on the seabed.
As part of the HERMES project, several sites of natural hydrocarbon seepage in the Euro...

European Margins Ecosystems Along
2015/7/3
During the European Commission’s Framework Six Programme, HERMES, we investigated three main areas along
the European margin, each characterized by the presence of seep-related structures exhibiting...

Deep-Sea Hotspot Ecosystems Technologies
2015/7/3
Cold seeps, hydrothermal vents, deep water coral reefs, and submarine canyon systems are hotspot habitats characterized by intermediate to high fluid
advection. They are shaped by a complex interpla...

The following is part 18 in a series on the National Science Foundation's Long-Term Ecological Research (LTER) Network.Visitparts one,two, three, four, five, six, seven,&...
A new study of the complex interplay between organisms and their environment shows that biodiversity—the variety of organisms living on Earth—is even more important to the healthy functioning of ecosy...
Shrinking habitats have adverse effects on world ecosystems--and ultimately people
Shrinking habitats have adverse world ecosystems ultimately people
2015/3/25
An extensive study of global habitat fragmentation--the division of habitats into smaller and more isolated patches--points to major trouble for the world's ecosystems.The study shows that 70 percent ...
Complementarity in water sources among dominant species in typical steppe ecosystems of Inner Mongolia, China
Water source Hydrogen stable isotope Soil moisture Winter half-year precipitation Plant water potential Functional traits

Water is the most important factor controlling plant growth, primary production, and ecosystem stability in arid and semi-arid grasslands. Here we conducted a 2-year field study to explore the contrib...
INVASIVE SPECIES AND PANNE ECOSYSTEMS: THE EFFECTS OF ATMOSPHERIC POLLUTION
invasive species nutrients
2015/1/16
Pannes are rare intradunal wetlands. Though small, they are known to exhibit extremely diverse and sensitive vegetation and are home to a number of reptile and amphibian species. In the United States,...

marginal effi ciency investment to analyze carbon
2014/12/19
Carbon (C) and nitrogen (N) cycles are coupled
in terrestrial ecosystems through multiple processes including photosynthesis, tissue allocation, respiration, N fixation,
N uptake, and decompos...
