Composition and Structure of Bottomland Forest Vegetation at the Tiak Research Natural Area, McCurtain County, Oklahoma

open access: yesOklahoma Native Plant Record, 2009
Although southeastern Oklahoma has substantial areas of bottomland forest, few studies exist of this vegetation type. We analyzed forest community structure at the Tiak Research Natural Area of the Ouachita National Forest on the Upper Gulf Coastal Plain.

Plant thresholds and community composition of coastal marsh–forest ecotones in the US Northeast

open access: yesEcosphere, Volume 17, Issue 4, April 2026.
Abstract Sea level rise is causing coastal salt marshes to migrate upslope into coastal forests and other terrestrial ecosystems. The factors that control marsh migration rates are not well understood, particularly in the US Northeast, where this phenomenon has received little attention. To determine the relationship between environmental variables and

Allometric relationships between total height and diameter for volume estimation of bottomland hardwood oaks in Arkansas

open access: yesFrontiers in Forests and Global Change
Bottomland hardwood (BLH) forests are a unique ecosystem that plays an important role in the provision of ecosystem services, both ecologically and economically. This study modeled allometric relationships between total tree height and diameter at breast

Genome Sequence and Population Genomic Analysis of Cronartium quercuum f.sp. fusiforme

open access: yesForest Pathology, Volume 56, Issue 1, February 2026.
ABSTRACT Fusiform rust, caused by Cronartium quercuum f. sp. fusiforme (Cqf), is the most severe disease of planted southern pines in the south‐eastern United States. Despite the critical role pathogen genomics play in disease outcomes, the population structure and genetic variability of Cqf remain poorly characterised.

Occurrence of natural tree cavities suitable for nesting wood ducks across South Carolina forest types

open access: yesThe Journal of Wildlife Management, Volume 89, Issue 7, September 2025.
Although evidence suggests >90% of the North American wood duck population nests in natural tree cavities, few studies have investigated the occurrence of these cavities across their southern breeding range. We aimed to determine forest and tree characteristics associated with the presence of cavities and cavities suitable for wood duck nesting and our
