Dam It, I’m Stranded: Evaluating Fish Stranding Downstream of Two Hydropeaking Dams in Northern Ontario

River Research and Applications, EarlyView.
ABSTRACT Globally, there has been an increase in the development and use of hydropower to produce energy. Hydropeaking is an operating regime that is used to meet real‐time energy demands; however, daily fluctuations in flows may result in fish becoming stranded.

The Transboundary Reach of the Columbia River: Cottonwood Colonization Followed Flow Moderation From the Columbia River Treaty Dams

River Research and Applications, EarlyView.
ABSTRACT The Columbia river provides the largest Pacific outflow in the Western Hemisphere and the greatest hydropower production of any North American river system. For hydropower generation and flood risk management, four massive water storage reservoirs followed the Columbia River Treaty between Canada and the United States, with three Canadian dams,

Quantifying aboveground herbaceous biomass in grassy ecosystems: a comparison of field and high‐resolution UAV‐LiDAR approaches

Remote Sensing in Ecology and Conservation, EarlyView.
The abundance of herbaceous vegetation in grassy ecosystems—which cover >25% of the world's land surface—is highly variable and impacts key ecological processes including carbon sequestration and support for grazing wildlife and livestock. Here, we present a method for using high‐resolution, UAV‐borne Light Detection and Ranging (LiDAR) to estimate ...

Measuring Strategic, Tactical, Complex and Simple Changes to Farm Systems

Systems Research and Behavioral Science, EarlyView.
ABSTRACT Agriculture is under increasing pressure to redesign farm systems. Governments are increasingly seeking to halt or reverse the damaging effects of agriculture on the environment. Adapting to climate change requires reconfiguring farm systems to withstand more variable, and historically more extreme, seasonal conditions and the constant demand ...

Exploring a Systems Engineering Approach to Modelling Human Communication

Systems Research and Behavioral Science, EarlyView.
ABSTRACT Communication is a crucial process for any successful purposeful human activity system as it mediates the information‐based relationships between a system's elements and parts, purpose(s) and boundaries. Human communication is more than just a process; it is a subsystem that interacts with other human activity systems, parts, elements and ...
