Climatic change is anticipated to alter disturbance regimes for many ecosystems. Among the most important effects are changes in the frequency, size, and intensity of wildfires....

There is growing concern that a warming climate will alter water supplies in many regions. Determining the best course of management and adaptation is an important task for...

Hypoxia (dissolved oxygen < 2 mg L–1) has emerged as a worldwide threat to coastal and estuarine ecosystems. Beyond direct mortality, secondary ecological impacts caused by...

The Tibetan Plateau is the world’s largest and highest plateau and holds the largest mass of ice on Earth outside the ice-sheets of Greenland and Antarctica, as well as abundant...

Strategies to characterize water quality vary widely, but regulatory approaches mainly consider single-value thresholds for individual parameters (e.g. minimum dissolved oxygen...

Rates of glacier mass loss in the northern Pacific coastal temperate rainforest (PCTR) are among the highest on Earth, and changes in glacier volume and extent will affect the...

Glacier ecosystems are a significant source of bioavailable, yet ancient dissolved organic carbon (DOC). Characterizing DOC in Mendenhall Glacier outflow (southeast Alaska) we...

We examine long-term streamflow and mass balance data from two Alaskan glaciers located in climatically distinct basins: Gulkana Glacier, a continental glacier located in the...

We synthesized an expert review of climate change implications for hydroecological and terrestrial ecological systems in the northern coastal temperate rainforest of North...

Increased motorized access used for subsistence hunting has created a challenge for land managers trying to balance the conservation of wildlife habitat with the greater...

Southeastern Alaska is a remote coastal-maritime ecosystem that is experiencing increased deposition of mercury (Hg) as well as rapid glacier loss. Here we present the results...

Pacific salmon migration timing can drive population productivity, ecosystem dynamics, and human harvest. Nevertheless, little is known about long-term variation in salmon...

Despite concerns over rapidly warming temperatures, an empirical understanding of climatic impacts on wild salmonid populations is limited. We tested how temperature and density...

Despite concerns over rapidly warming temperatures, an empirical understanding of climatic impacts on wild salmonid populations is limited. We tested how temperature and density...

We used natural abundance δ13C, δ15N, and Δ14C to compare trophic linkages between potential carbon sources (leaf litter, epilithic biofilm, and particulate organic matter) and...

A study of the freshwater discharge into the Gulf of Alaska (GOA) has been carried out. Using available streamgage data, regression equations were developed for monthly flows....

Bacterial biofilms are highly resistant to common antibacterial treatments, and several physiological explanations have been offered to explain the recalcitrant nature of...

Successful endangered species conservation requires understanding, support, and participation from user groups and stakeholders in conjunction with biological information. A...

Since 2002, the headwaters of the Colorado River and nearby basins have experienced extensive changes in land cover at sub-annual timescales. Widespread tree mortality from bark...

Climate warming is likely to cause both indirect and direct impacts on the biophysical properties of stream ecosystems especially in regions that support societally important...
