Sediment Trapping by Dams Creates Methane Emission Hot Spots
|
Inland waters transport and transform sub- stantial amounts of carbon and account for ∼18% of global methane emissions. Large reservoirs with higher areal met... |

Characterizing coal and mineral mines as a regional source of stress to stream fish assemblages
|
Mining impacts on stream systems have historically been studied over small spatial scales, yet investigations over large areas may be useful for characterizing ... |

The links between ecosystem multifunctionality and above- and belowground biodiversity are mediated by climate
|
Plant biodiversity is often correlated with ecosystem functioning in terrestrial ecosystems. However, we know little about the relative and combined effects of ... |

Multidecadal to multicentury scale collapses of Northern Hemisphere monsoons over the past millennium
|
Late Holocene climate in western North America was punctuated by periods of extended aridity called megadroughts. These droughts have been linked to cool easter... |

A phantom road experiment reveals traffic noise is an invisible source of habitat degradation
|
Decades of research demonstrate that roads impact wildlife and suggest traffic noise as a primary cause of population declines near roads. We created a “phant... |

A large source of low-volatility secondary organic aerosol
|
Forests emit large quantities of volatile organic compounds (VOCs) to the atmosphere. Their condensable oxidation products can form secondary organic aerosol, a... |

Predicting a change in the order of spring phenology in temperate forests
|
The rise in spring temperatures over the past half-century has led to advances in the phenology of many nontropical plants and animals. As species and populatio... |

Time to Adapt to a Warming World, But Where’s the Science?
|
With dangerous global warming seemingly inevitable, users of climate information—
from water utilities to international aid workers—are turning to climate ... |

Increased River Alkalinization in the Eastern U.S.
|
The interaction between human activities and watershed geology is accelerating long-term changes in the carbon cycle of rivers. We evaluated changes in bicarbon... |

DO CARBON OFFSETS WORK? THE ROLE OF FOREST MANAGEMENT IN GREENHOUSE GAS MITIGATION
|
As forest carbon offset projects become more popular, professional foresters are providing their expertise to support them. But when several members of the Soci... |

Duality in climate science
|
Delivery of palatable 2 °C mitigation scenarios depends on speculative negative emissions or changing the past. Scientists must make their assumptions transpar... |

How wide is a stream? Spatial extent of the potential ‘‘stream signature’’ in terrestrial food webs using meta-analysis
|
The magnitude of cross-ecosystem resource subsidies is increasingly well recognized; however, less is known about the distance these subsidies travel into the r... |

Forests fuel fish growth in freshwater deltas
|
Aquatic ecosystems are fuelled by biogeochemical inputs from surrounding lands and within- lake primary production. Disturbances that change these inputs may af... |

Multi-year drought-induced morbidity preceding tree death in Southeastern US forests
|
Recent forest diebacks combined with threats of future drought focus attention on the extent to which tree death is caused by catastrophic events as opposed to ... |

Global non-linear effect of temperature on economic production
|
Growing evidence demonstrates that climatic conditions can have a profound impact on the functioning of modern human societies (1,2), but effects on economic ac... |

Sagebrush carrying out hydraulic lift enhances surface soil nitrogen cycling and nitrogen uptake into inflorescences
|
Plant roots serve as conduits for water flow not only from soil to leaves but also from wetter to drier soil. This hydraulic redistribution through root systems... |
