The taxonomy of annulate [possessing a ring-like structure on the stipe (stem) of the basidiocarp (mushroom, fruiting body, basidioma) that is the remnant of the ruptured veil on the underside of the cap] Armillaria (Figs.
Characterization of physical fuel distributions across heterogeneous landscapes is needed to understand fire behavior, account for smoke emissions, and manage for ecosystem resilience. Remote sensing measurements at various scales inform fuel maps for improved fire and smoke models.
The emerging bioeconomy requires new supply chain paradigms for biomass materials to reach processing centers. Forest bio-hubs can be thought of as networks of collection points to facilitate biomass supply chains that feed from forest to central processing facilities.
Several plant traits are associated with resistance to fire, thus fire-resistant species may give rise to more fire-resistant landscapes. However, upscaling from plant traits to landscape- and regional-scale fire effects remains a challenge.
Food web analyses offer useful insights into understanding how species interactions, trophic relationships, and energy flow underpin important demographic parameters of fish populations such as survival, growth, and reproduction.
Dissolved organic carbon (DOC) and nitrogen (DON) are important energy and nutrient sources for aquatic ecosystems. In many northern temperate, freshwater systems DOC has increased in the past 50 years.
Alaska is a land of extremes. This includes its climate, which ranges from mild to maritime in its southeast, to arctic in its northern slope. Alaska is also at the forefront of experiencing changes in climate and climate variability, including higher temperatures and more precipitation.
Climate change can act to facilitate or inhibit invasions of non-native species. Here, we address the influence of climate change on control of non-native common carp (hereafter, carp), a species recognized as one of the “world’s worst” invaders across the globe.
Degraded floodplains and valley floors are restored with the goal of enhancing habitat for native fish and aquatic-riparian biota and the protection or improvement of water quality.
