Summary Callus cultures of two closely related pine species, Pinus palustris Mill. and Pinus elliottii Engelm., initiated from hypocotyl explants and grown under identical cultural conditions on the same chemically defined medium are strikingly different in pigmentation and plastid development. P.

Dendroecological analysis of a longleaf pine Pinus palustris forest in Mississippi
Plant Ecology, 1991A climate model with time varying parameters was fit to longleaf pine (Pinus palustris) tree rings collected from the proposed Harrison Research Natural Area of the De Soto National Forest in southern Mississippi. The purpose of the analysis was to determine if any unexpected disturbances had influenced the growth of the trees.

Conservation management of Pinus palustris ecosystems from a landscape perspective
Applied Vegetation Science, 2006AbstractQuestion: Do case studies from silvicultural and restoration studies and applied conservation management in second‐growth Pinus palustris stands provide unique insights for conservation models?Methods: A review of management paradigms that conserve the high biological diversity and rare species, drawn from characteristics in both second‐growth ...

A Study of the Ignition Mechanism for Dead Pinus Palustris Needles
2022Combinations of cumulative impacts of drought, invasive species, climate variability, and ever-expanding wildland-urban interface make landscapes more susceptible to devastating wildland fires. To treat the increasing risks of wildland fires, one of the ways is to mitigate the risk of ignition, which requires a solid understanding of the ignition ...

Physical and acoustic response of Pinus palustris to fire
The Journal of the Acoustical Society of America, 2021Crackling sounds from burning vegetation provide information to fire-experienced land managers regarding the combustion process. These acoustic impulse events can inform practitioners of a variety of situations, from the type of vegetation involved and relative “dryness,” to alerting wildland fire fighters to increased burning along tree boles and in ...

The Population Dynamics of a Long-Lived Conifer (Pinus palustris)
The American Naturalist, 1988We investigated the demography and spatial pattern of an old-growth longleaf pine population using a large plot in which all trees of at least 2 cm in dbh were mapped and tagged for individual recognition. The population was of uneven age and size; tree size correlated positively with tree age. Large or old trees were only loosely aggregated, forming a

Variation among individuals in cone production in Pinus palustris (Pinaceae)
American Journal of Botany, 2012• Premise of the study: Reproductive output varies considerably among individuals within plant populations, and this is especially so in cone production of conifers. While this variation can have substantial effects on populations, little is known about its magnitude or causes.• Methods: We studied variation in cone production for 2 years within a ...

The role of smoldering in the ignition of Pinus palustris needles
Fire Safety JournalThe pyrolysis process and the critical ignition conditions of dead Pinus palustris needles were studied experimentally to understand the role of smoldering in the onset of flaming combustion. The results obtained show that methane (CH), carbon monoxide (CO), carbon dioxide (CO), and water vapor (HO) are the main constituents of the pyrolysis gases ...
