On the west slopes of the Cascades, forest development is shaped by extensive stand-replacing (SR) fires and more frequent fires that cause predominantly non-stand replacing (NSR) effects. These NSR…
Generative AI is changing the way ecologists work, creating new opportunities to make sense of complex data and move research forward efficiently. But using AI tools also means confronting important…
Northern spotted owl populations are approaching or have already crossed functional extinction across large areas of the Pacific Northwest. Researchers used artificial intelligence and advanced…
Species interactions, such as competition or facilitation, are part of what shapes how populations are distributed in a landscape. Researchers used a 15-year dataset on bird distribution and abundance…
In a recent essay in Nature, former Lead PI of the LTER program, Michael Paul Nelson, draws on lessons long familiar in the humanities. Nelson argues that we should shift our priorities toward…
Growing evidence has shown that changes in landscape-level factors by accelerated land-use change can shape soil pathogenic fungal diversity. Researchers assessed how pathogenic fungal diversity in…
In late June 2021, multiple days of record-breaking heat caused an unprecedented amount of foliage death in the forests of the Pacific Northwest. Portions of tree canopies with healthy green foliage…
Understanding the mechanisms that enable species to coexist is essential for explaining community structure and biodiversity. Researchers compared the diets of two dominant stream predators in western…
Using data compiled from around the world and over decades, researchers showed that large wood mobility in rivers is infrequent and highly variable, influenced by a combination of wood characteristics…
Forest plantations are widespread globally. Young forest plantations (hereafter young forests) differ from natural old-growth forests (hereafter old forests) in above- and below-ground structures…
Forest succession theory predicts long-term dynamics of tree species and ecosystem biomass through time, with shifts from early- to late seral species and cessation of live biomass accumulation being…
OSU graduate student, Matthew Weldy, is harnessing the power of AI and open-source modeling to process millions of hours of recorded acoustic data of birds across the forests of the Pacific Northwest…
