Karr will present the paradox: As scientific understanding of Earth and the effects of humans on Earth systems expand, the threats to Earth's living systems—human and nonhuman—worsen. He will ask: How can we be smarter and more knowledgeable, yet ignore so many of the lessons of that knowledge? He will argue that humanity ...

Conquest will review traditional sample designs. Next, she will discuss recent advances: ranked set sampling and multiple-panel sampling. She will describe "Visual Sample Plan" software, and then offer some conclusions.

Rattanaviwatpong will describe a study about water resource conflicts in northern Thailand. She will provide an overview of the research, including the study site, the water resource problem, research objectives, implementation, results, conclusions, and management implications.

Quinn will describe a study of salmon predation by bears in Alaska. The study looked at the controls on the number and proportion of salmon killed in a creek each year. Quinn will outline the observed patterns: 1. Bears kill a higher proportion of the salmon in narrow than wide streams. 2.The number of salmon killed reaches ...

Montgomery will review the importance of soil in sustaining civilizations. He will ask the question: can soil erosion limit the lifespan of civilizations? He will discuss contemporary and long-term (geological) erosion rates -- and agricultural erosion rates in particular.

Montgomery will discuss the role of coarse woody debris in river ecosystems. He concludes that one of the few salmon conservation strategies that might work over a long run would be to restore a network of forested river corridors along river floodplains.

Ryan will describe a research study comparing watershed management strategies in Washington and Oregon. She will review each state's plan to obtain and sustain participation, as well as their balance of planning and projects. She will discuss the issues involved with building organizational capacity, and what we can learn ...

Khagram will discuss adaptive management of existing dams for sustainable development. He will review environmental impacts and mitigation, social impacts, decision making and governance, water quality and human health and safety. Finally, he will talk about decommissioning dams, and policy and practice implications.

Mouton will describe his research into stream prediction. In his study, he examined the effects of digital elevation model (DEM) grid size for stream network predictions in the northwestern United States to test the accuracy of high-resolution LiDAR (Light Detection and Ranging) digital elevation data. He will describe the ...

Karr will discuss humanity's effects on salmon and rivers. He will identify the core problem: flawed indicators and models endorse values that promote unsustainable lifestyles. He will argue that we need improved indicators, so that we can create better assessments and more inclusive policy processes. He will present the case ...
