Carbonate communities:The activity of anaerobic methane oxidizing microbes facilitates
precipitation of vast quantities of authigenic carbonate at methane seeps. Here we demonstrate
the significant role of carbonate rocks in promoting diversity by providing unique habitat
and food resources for macrofaunal assemblages at seeps on the Costa Rica margin
(400–1850 m)....

BACKGROUND: Many commentators on ‘‘direct-to-consumer’’ genetic risk information have raised concerns that giving results
to individuals with insufficient knowledge and training in genomics may harm consumers, the health care system, and
society. In response, several commercial laboratories offering genomic risk profiling have shifted to more traditional ‘‘direct-to-provider’’ (DTP) marketing strategies,...

Ecological niche theory holds that species distributions are shaped by a large and complex suite of interacting factors. Species distribution models (SDMs) are increasingly used to describe species’ niches and predict the effects of future environmental change, including climate change. Currently, SDMs often fail to capture the complexity of species’...

Aerodynamic roughness heights of 1–3 cm were obtained from measured wind profiles collected among
fields of gravel-mantled megaripples in the high desert of the Puna region of northwestern Argentina.
Roughness height appears to be relatively insensitive to the angle at which the wind was incident upon
the bedforms throughout the...

Ongoing greenhouse gas emissions can modify climate processes and induce shifts in ocean temperature, pH, oxygen
concentration, and productivity, which in turn could alter biological and social systems. Here, we provide a synoptic global
assessment of the simultaneous changes in future ocean biogeochemical variables over marine biota and their broader...

More than US$21 billion is spent annually on biodiversity conservation. Despite their importance for preventing or slowing extinctions and preserving biodiversity, conservation interventions are rarely assessed systematically for their global impact. Islands house a disproportionately higher amount of biodiversity compared with mainlands, much of which is highly threatened with extinction....
Ecosystem services play a crucial role in sustaining human well-being and economic viability. People benefit substantially from the delivery of ecosystem services, for which substitutes usually are costly or unavailable. Climate change will substantially alter or eliminate certain ecosystem services in the future. To better understand the consequences of climate...

Between 2007 and 2009, researchers from Green Point Consulting, Oregon State University, and the South Slough National Estuarine Research Reserve collected data on ecological and physical characteristics at five high-quality “least disturbed” tidal wetland sites in four Oregon estuaries.
The reference sites included in this project are (1) Blind Slough...

Headwater streams comprise nearly 90% of the total length of perennial channels in global catchments. They mineralize organic carbon entering from terrestrial systems, evade terrestrial carbon dioxide (CO₂ ), and generate and remove carbon through in-stream primary production and respiration. Despite their importance, headwater streams are often neglected in global...
