Forest disturbance across the conterminous United States from 1985–2012: The emerging dominance of forest decline
|
Evidence of shifting dominance among major forest disturbance agent classes regionally to globally has been emerging in the literature. For example, climate-rel... |

How does climate change cause extinction?
|
Anthropogenic climate change is predicted to be a major cause of species extinctions in the next 100 years. But what will actually cause these extinctions? For ... |

The Three Horsemen of Riches: Plague, War, and Urbanization in Early Modern Europe
|
How did Europe escape the “Iron Law of Wages?” We construct a simple Malthusian model with two sectors and multiple steady states, and use it to explain why... |

Old Trees: Extraction, Conservation Can Coexist
|
BECAUSE LARGE OLD TREES ARE ESSENTIAL FOR FOREST ECOSYSTEM INTEGRITY AND BIODIVERsity,
timber extraction in managed forests should preferentially be concentrat... |

Sectoral contributions to surface water stress in the coterminous United States
|
Here, we assess current stress in the freshwater system based on the best available data in order to understand possible risks and vulnerabilities to regional w... |

Drought’s legacy: multiyear hydraulic deterioration underlies widespread aspen forest die-off and portends increased future risk
|
Forest mortality constitutes a major uncertainty in projections of climate impacts on terrestrial ecosystems and car- bon-cycle feedbacks. Recent drought-induce... |

Temporal dynamics of a commensal network of cavity-nesting vertebrates: increased diversity during an insect outbreak
|
Network analysis offers insight into the structure and function of ecological
communities, but little is known about how empirical networks change over time du... |

Generic Indicators for Loss of Resilience Before a Tipping Point Leading to Population Collapse
|
Theory predicts that the approach of catastrophic thresholds in natural systems (e.g., ecosystems,
the climate) may result in an increasingly slow recovery fro... |
|
Life history predicts risk of species decline in a stochastic world
|
Understanding what traits determine the extinction risk of species has been a long-standing challenge. Natural populations increasingly experience reductions in... |

Diverse pollinator communities enhance plant reproductive success
|
Understanding the functional consequences of biodiversity loss is a major goal of ecology. Animal-mediated pollination is an essential ecosystem function and se... |

Rising air and stream-water temperatures in Chesapeake Bay region, USA
|
Monthly mean air temperature (AT) at 85 sites and instantaneous stream-water temperature (WT) at 129 sites for 1960–2010 are examined for the mid-Atlantic reg... |

The challenge of hot drought
|
1st paragraph: rought is heating up around the warm- ing world. Particularly hot drought has cost more than US$40 billion and claimed 218 human lives since 2010... |
|
Tree mortality from drought, insects, and their interactions in a changing climate
|
Climate change is expected to drive increased tree mortality through drought, heat stress, and insect attacks, with manifold impacts on forest ecosystems. Yet, ... |

Changes in Wind Pattern Alter Albatross Distribution and Life-History Traits
|
Westerly winds in the Southern Ocean have increased in intensity and moved poleward. Using
long-term demographic and foraging records, we show that foraging ra... |

Heat stress related dairy cow mortality during heat waves and control periods in rural Southern Ontario from 2010–2012
|
Background: Heat stress is a physiological response to extreme environmental heat such as heat waves. Heat stress can result in mortality in dairy cows when ext... |

Analysing fossil-fuel displacement
|
It is commonly assumed that fossil fuels can be replaced by alternative forms of energy. Now research challenges this assumption, and highlights the role of non... |

A systems approach to evaluating the air quality co-benefits of US carbon policies
|
Because human activities emit greenhouse gases (GHGs) and conventional air pollutants from common sources, policy designed to reduce GHGs can have co-benefits f... |

Three decades of multi-dimensional change in global leaf phenology
|
We show that the phenology of vegetation activity changed severely (by more than 2 standard deviations in one or more dimensions of phe- nological change) on 54... |
