Heavy metal contamination in water systems driven by industrialization and urbanization is a primary concern for society. The development of efficient remediation methods to reduce heavy metal contamination in water is necessary. Biochar has emerged as a promising adsorbent for heavy metals due to its unique physicochemical properties. This study investigated the effect of biochars manufactured from 12 different wood species on lead ion (Pb(II)) removal capacity in aqueous solutions. The 12 different wood species include two softwoods and 10 hardwoods. The physicochemical properties and...

Puerto Rico (PR) and the US Virgin Islands (VI), two archipelagos located in the Caribbean region, possess forest ecosystems with high species diversity, which remain largely underrepresented in forest modeling research compared to temperate forests. Accurately characterizing tree allometry is essential for monitoring forest status over time and predicting tree growth and yield in sustainable forest management. Height-diameter relationship models, denoted as H–D models, are widely used in forestry practice since they effectively reduce the time and cost of field data collection and provide...

As a forest-dependent species, the endangered Indiana bat (Myotis sodalis) is reliant on large-diameter tree roosts (hereafter, “roosts”), which are usually snags. Such large trees develop as a product of time and species-specific growth rates. To better understand the ecology of bat roost habitat, we explore the putative trade-offs between tree age, size, and growth rates on the development of roosts. Specifically, we quantify the age, size, and longevity of roosts of Indiana bats using dendrochronology at three study sites across the species’ range in the eastern USA. On average, roosts...

Myotis septentrionalis (Northern Long-eared Bat) has experienced severe population declines due to the impacts of white-nose syndrome, although some populations along the Atlantic Coast appear to be persisting. Our objectives were to document the presence of Northern Long-eared Bats across the Coastal Plain of South Carolina and describe roost characteristics and other aspects of the bats’ ecology. We captured 45 Northern Long-eared Bats from April to August 2017–2024 across 4 sites. We radio-tagged 30 bats and tracked them to 99 day roosts. Almost all (92.9%) roosts were in pines,...

Polyploidization is becoming an increasingly important subject in ecology and invasion biology. To date, the role of polyploidy in the success of species invasions remains unclear. Here, we explore the associations between ploidy levels and seed size, reproductive mode, life form, time after introduction and range size of non-native plants introduced to North America, and whether polyploidization is related to invasion success.Using data on 1804 non-native plant species in continental North America with information on chromosome numbers, we conducted comparative, correlation and regression...

Previous studies have compared various eco‐physiological aspects among C 3 , C 4 , and Crassulacean Acid Metabolism (CAM) plants, mostly using native species. The variation in key genetic and life‐history traits and their distribution among non‐native plants with the three photosynthetic pathways remains poorly understood. Here, we examine whether the photosynthetic pathways of non‐native plants in North America are linked to several major species traits and their current distributions. Location: North America.We collate genetic and life‐history data on chromosome number (ploidy levels),...

1. Stewardship is broadly defined as ‘universal responsibility of humanity to care for the planet, to ensure that it can continue to provide the essential natural resources for life’. Stewardship practices shape ecosystems, create diverse biocultural landscapes, and can enhance the productivity, availability and health of plants used by Indigenous Peoples for traditional foods, fibres and medicines.2. In this paper, we argue that care is one key component that differentiates Indigenous stewardship from other forms of resource management and has the potential to cross cultural and institutio...

The COVID-19 pandemic introduced unprecedented volatility into the US manufactured wood products market, with the price of softwood lumber nearly quadrupling within a year, reaching its highest level since 1995. This paper examines the substantial price fluctuations in major wood products, focusing on Spruce-Pine-Fir and Southern Yellow Pine softwood lumber, as well as Oriented Strand Board sheathing. Using vector autoregressive and vector error correction models, this study investigates the relationships between wood product prices and various macroeconomic factors. The analysis reveals...

Corrigendum (April 2026): Incorrect units of measure on table A-42 (thousand dry tons) were replaced with the correct units of measure (thousand cubic feet).This publication provides authoritative updates to the Nation’s forest resource statistics reported in “Forest Resources of the United States, 2017” and the 2020 Resources Planning Act (RPA) Assessment using adapted Forest Inventory and Analysis data. Resource data tables present estimates of forest area, volume, mortality, growth, removals, timber products output, and more in various ways within the context of changes since 1953.Downlo...

Giant reed ( Arundo donax ) has invaded biologically diverse riparian ecosystems in warm and arid regions globally, yet its impacts on wildlife are still poorly understood. Resolving the multi-taxa, scale-explicit impacts of giant reed in the broader context of the riparian vegetation mosaics that support wildlife can help target ecological restoration efforts. We quantified effects of giant reed and other dominant riparian vegetation on bird and butterfly habitat occupancies at two spatial scales along the Rio Grande in west Texas, USA. Birds and butterflies are diverse in riparian...
