Abstract Lidar‐derived forest structural diversity (FSD) metrics—including measures of canopy height, vegetation arrangement, cover (CC), complexity and leaf area density—are increasingly used to describe characteristics can be infer many ecosystem functions. Despite broad adoption, the importance spatial resolution (grain extent) over which these metrics are calculated remains largely unconsidered. Often researchers will quantify FSD at grain size process interest without considering scale...
Abstract Aim Rapid global change is impacting the diversity of tree species and essential ecosystem functions services forests. It therefore critical to understand predict how spatially distributed within among forest biomes. Satellite remote sensing platforms have been used for decades map structure function but are limited in their capacity monitor by relatively coarse spatial resolution complexity scales at which different dimensions biodiversity observed field. Recently, airborne making...
Plant functional diversity is strongly connected to photosynthetic carbon assimilation in terrestrial ecosystems. However, many of the plant traits that regulate capacity, including foliar nitrogen concentration and leaf mass per area, vary significantly between within types vertically through forest canopies, resulting considerable landscape-scale heterogeneity three dimensions. Hyperspectral imagery has been used extensively quantify across a range ecosystems but generally limited...
Global declines in biodiversity have the potential to affect ecosystem function, and vice versa, both terrestrial aquatic ecological realms. While many studies considered biodiversity-ecosystem function (BEF) relationships at local scales within single realms, there is a critical need for more examining BEF linkages among across scales, trophic levels. We present framework linking abiotic attributes, productivity, inland review examples of major ways that form realms–cross-system subsidies,...
Abstract. The fortedata R package is an open data notebook from the Forest Resilience Threshold Experiment (FoRTE) – a modeling and manipulative field experiment that tests effects of disturbance severity type on carbon cycling dynamics in temperate forest. Package consist measurements pools fluxes ancillary to help analyze interpret over time. Currently includes metadata first three FoRTE seasons, serves as central, updatable resource for project team, intended external users course...
Abstract The COVID-19 pandemic has created unprecedented challenges in the way USDA Forest Service conducts business. Standard data collection methods were immediately challenged due to travel restrictions and uncertainty regarding when it would be safe return a “business as usual” approach. These met with an inspiring collaboration between forest health specialists directly involved annual Aerial Detection Survey (ADS) program remote sensing from academia. This group worked together...
In Michigan’s Upper Peninsula, sand dunes are widespread on the sandy floor of former Glacial Lake Algonquin, and many nearby uplands also have thin mantles loess. Previous work concluded that these formed during early Holocene, long after lake had drained. Where migrated against bedrock uplands, accreted into larger dune complexes. South east complexes, mantled with well-sorted sediment, comparatively rich in finer sands much like thin, locally sourced loess deposits Wisconsin Michigan....

President Biden’s executive order, ‘Strengthening the Nation's Forests, Communities, and Local Economies,’ (EO#14072, April 22, 2022) acknowledges interest in mature old-growth (MOG) forests by directing U.S. Federal agencies to define inventory these resources on United States Forest Service (USFS) Bureau of Land Management (BLM) lands. We propose using an effective enduring forest classification system that could be adaptable social paradigms, monitoring data streams, scientific...
<p>Foliar nitrogen concentration (foliar N) and leaf mass per area (LMA) have been identified as key drivers of plant functional diversity are strongly correlated with photosynthetic carbon assimilation in terrestrial ecosystems. However, these traits not static between among species, instead tradeoffs light interception, capacity, construction costs (e.g. economics spectrum) lead to significant variation across landscapes. This can considerable differences rates at the level,...
