Quantifying water overconsumption using a new water supply sustainability indicator

Communities around the globe are experiencing great difficulty in constraining their water consumption within the limits of available, renewable freshwater supplies. When water consumed from freshwater supplies exceeds natural replenishment from snowmelt, rainfall, or aquifer rec...

Shifts in avian community composition across longleaf pine seral stages in a montane upland system

Longleaf pine ( Pinus palustris ) ecosystems historically covered much of the Southeastern United States but declined substantially due to land-use change and fire suppression, driving losses in associated avifauna. This prompted restoration efforts to reestablish frequent fire a...

Using ICESat-2 ATL08 heights and Landsat time series to assess the age-height relationship of southern yellow pines in the US

It is critical to understand the age-height relationship in actively managed pine plantations to evaluate forest productivity and inform sustainable forest management practices. This study utilized the spaceborne lidar data from ICESat-2 ATL08 and Landsat-derived disturbance maps...

Native and non-native ambrosia beetles compete for deadwood resources

A consequence of biological invasion is competition between native and non-native species. Ambrosia beetles (Curculionidae: Scolytinae, Platypodinae) are among the most successful insect invaders, but their impact in natural settings is poorly understood. Across the United States...

Identifying Research Priorities for the Development of High-Integrity Forest Carbon Credits

Abstract In the United States, voluntary carbon markets have gained significant traction in recent years. However, many offset standards, protocols, and credit ratings have come under scrutiny from the public and investors for failing to produce real or sustainable carbon offsets...

A Copula‐Based Regression Method to Predict Sediment Concentration and Load in Rivers Using Streamflow Data

Abstract Pollution and deposition of sediments in rivers and streams are critical environmental, ecological, navigational, and recreational concerns. While several well‐known watershed models such as SWAT (Soil and Water Assessment Tool) and HSPF (Hydrological Simulation Program‐...

Contrasting Growth and Physiological Response Profiles of Three Native Alpine Elymus Forage Grasses Under Combined Cadmium and PEG-6000-Induced Osmotic Stress

The co-occurrence of soil drought and cadmium (Cd) pollution represents an important combined-stress scenario in degraded alpine grasslands, yet comparative responses of native Elymus forage grasses remain poorly resolved. Seedlings of E. sibiricus cv. Chuancao, E. breviaristatus...
