Estimating density of an unmarked, low‐density wild turkey population

open access: yesEcosphere, Volume 16, Issue 12, December 2025.
Abstract Eastern wild turkey (Meleagris gallopavo silvestris, hereafter turkey) populations have been declining across the southeastern United States, including Oklahoma. Little is known about current turkey population numbers, as no robust method has been established for density estimation.

Comparison of Planted Loblolly and Slash Pine Performance in Southeast Texas [PDF]

open access: yes, 1993
The performance of young (less than 10 yr) loblolly (Pinus taeda L.) and slash (Pinus elliottii Engelm.) pine trees was compared on planted sites in southeast Texas. Performance was compared for: total tree height; tree diameter; heigh to live tree crown;

Root‐zone enrichment of particulate and nonparticulate organic carbon and nitrogen under grassland management and woodlands across a soil texture gradient in North Carolina, USA

open access: yesGrassland Research, Volume 4, Issue 4, Page 341-351, December 2025.
Particulate organic carbon and nitrogen are sensitive indicators of long‐term management influence on soil organic matter. A unique calculation method separated pedogenic from management contributions by establishing a baseline at 30‐cm depth in each soil profile.

A modified stand table projection model for unmanaged loblolly and slash pine plantations in east Texas [PDF]

open access: yes, 2011
Four methodologies to project future trees per acre by diameter class were compared to develop a new modified stand table projection growth model for unmanaged loblolly pine (Pinus taeda L.) and slash pine (Pinus elliottii Engelm.) plantations in East ...

RGB‐Based Deep Learning for Freeze Damage Detection in Strawberry: Comparing Scratch and Transfer Learning Approaches on Custom Data

open access: yesPlant Direct, Volume 9, Issue 12, December 2025.
ABSTRACT Freeze damage presents a critical threat to agricultural productivity, resulting in substantial economic losses, especially in sensitive crops such as strawberries. Traditional methods for assessing freeze damage, including manual inspection, are time‐consuming, subjective, and labor‐intensive.

ECONOMICS OF CELLULOSIC ETHANOL PRODUCTION: GREEN LIQUOR PRETREATMENT FOR SOFTWOOD AND HARDWOOD, GREENFIELD AND REPURPOSE SCENARIOS [PDF]

open access: yesBioResources, 2011
Green liquor pretreatment, a technology presently used worldwide in hundreds of kraft pulp mills, is proposed in this work as a potential pretreatment pathway for the efficient conversion of lignocellulosic biomass into ethanol.

Comparative in silico analysis of SSRs in coding regions of high confidence predicted genes in Norway spruce (Picea abies) and Loblolly pine (Pinus taeda) [PDF]

open access: yes, 2015
Background: Microsatellites or simple sequence repeats (SSRs) are DNA sequences consisting of 1-6 bp tandem repeat motifs present in the genome. SSRs are considered to be one of the most powerful tools in genetic studies.

Comparison of methods for estimating wild turkey poult survival

open access: yesWildlife Society Bulletin, Volume 49, Issue S1, December 2025.
Wild turkey poult survival is a challenging metric to measure in wild turkey reproduction, and interpreting this information can have significant implications for managers at the population scale. Flushing wild turkey broods and radio‐tagging poults produced similar estimates of poult survival over a 56‐day monitoring period post‐hatching. Both methods

Use of a generalized sigmoid growth function to predict site index for unmanaged loblolly and slash pine plantations in east Texas [PDF]

open access: yes, 2006
A generalized sigmoid growth function was used in this study to model site index (SI) for unmanaged or lowintensity managed loblolly pine (Pinus taeda, L.) and slash pine (Pinus elliottii, Engelm.) plantations in east Texas.
