The Fate of Nitrogen and Phosphorus in the PCTR

The Pacific coastal temperate rainforest (PCTR) is projected to become warmer and wetter in the coming decades, with significant implications for how nutrients are exchanged across ecosystem boundaries. With hydrologic shifts, studies have shown that the amount and type of carbon being transported from coastal watersheds into marine ecosystems is changing. But how will the movement of nitrogen and phosphorus between land and sea be impacted? Nitrogen and phosphorus play a role in periphyton growth, community composition, and harmful algal bloom occurrences. As human sources of these nutrients are growing, there is a greater need to understand the implications of changing nutrient export on downstream ecosystem processes.

Climate change alters coastal processes in North America’s largest temperate rainforest

In North America’s largest remaining temperate rainforest, coastal marine environments are intrinsically linked with the land through the delivery of nutrients that drive ocean productivity. Coastal margins are a unique study area for scientists working to understand the ecological processes of coastal environments, and what they might look like in our changing climate.

Carbon in the Pacific Coastal Temperate Rainforest: New Research

Beneath the canopy of North America’s largest remaining old-growth forest, globally-significant amounts of carbon are captured from the atmosphere by plant life cycled through the soil, rivers, and water bodies of coastal Southeast Alaska and British Columbia. The Pacific Coastal Temperate Rainforest (PCTR) is a key region for research into carbon stocks and movement between forested and glacierized areas and the highly productive coastal waters.

How are Southeast Alaskans responding to COVID-19? Take this survey to help researchers understand the impacts

ACRC researchers at the University of Alaska Southeast are working with the Sitka Sound Science Center, the Central Council of the Tlingit-Haida Tribes, and RAND Corporation to gain a better understanding of how Southeast Alaskans perceive the risk of COVID-19 and consequently how Southeast Alaskans are prepared against and responding to COVID-19.

New study highlights the role of overlooked ecological factors in salmon restoration success

In the Methow River of northern Washington state, imperiled populations of salmon and steelhead are at a mere fraction of their historic numbers. Restoration efforts can help bring back these populations, but how do managers prioritize which methods to employ, and where?

ACRC welcomes new leadership this fall

This fall, ACRC marks a new era as long-time director Allison Bidlack transitions into a new role at the NOAA National Marine Fisheries Service as Deputy Director of the Auke Bay Laboratory. Allison has led ACRC for over eight years, growing ACRC as a premier research institute in the north Pacific coastal temperate rainforest with a dynamic team of scientists, staff, and faculty. Though she will be missed, we look forward to continuing collaboration with her in her new role at NOAA.
