Holocene soil-geomorphic surfaces influence the role of salmon-derived nutrients in the coastal temperate rainforest of Southeast Alaska

The influence of salmon-derived nutrients (SDN) is widely accepted as a potential factor in the maintenance of aquatic and terrestrial productivity in North American Coastal rainforests. Holocene alluvial landforms are intimately connected with the return of anadromous salmon, but the influence of the soils that occupy these landforms and support this important...

Factors influencing line officers' decisions about National Environmental Policy Act project design and development.

Prior to the existence of the National Environmental Policy Act (NEPA), Forest Service district rangers had considerable latitude to make resource management decisions and execute management plans with relatively little encumbrance by documentation and process requirements. Today there appear to be differences not only in the district ranger population, but in the...

Microsatellite DNA in genomic survey sequences and UniGenes of loblolly pine

Genomic DNA sequence databases are a potential and growing resource for simple sequence repeat (SSR) marker development in loblolly pine (Pinus taeda L.). Loblolly pine also has many expressed sequence tags (ESTs) available for microsatellite (SSR) marker development. We compared loblolly pine SSR densities in genome survey sequences (GSSs) to those in non-redundant...

Stand dynamics of mixed red alder-conifer forests of southeast Alaska.

Stand structure and dynamics were evaluated in mixed red alder (Alnus rubra Bong.) - conifer forests of southeast Alaska. We assessed stand development, tree density, total basal area, diameter distribution of live and dead trees, height distribution of live trees, and mean diameter of all and largest conifers in 40-year-old red alder - conifer...

Hydromorphic soil development in the coastal temperate rainforest of Alaska

Predictive relationships between soil drainage and soil morphological features are essential for understanding hydromorphic processes in soils. The linkage between patterns of soil saturation, reduction, and reductimorphic soil properties has not been extensively studied in mountainous forested terrain. We measured soil saturation and reduction during a 4-yr period in...

Novel approach to evaluate the dynamic variation of wind drift and evaporation losses under moving irrigation systems

The increased need for water and food security requires the development of new approaches to save water through irrigation management strategies, particularly for center pivot irrigation. To do so entails monitoring of the dynamic variation in wind drift and evaporation losses (WDELs) of irrigation systems under different weather conditions and for relatively long time...

DNA fingerprinting sets for four southern pines

DNA markers can provide valuable genetic information for forest tree research, breeding, conservation, and restoration programs. When properly evaluated, selected sets of DNA markers can be used to efficiently get information about genetic diversity in regions, forests, or stands, or in seed lots and orchards. Selected markers also can be used to determine parentage or...

Microsatellite primers for the Pacific Northwest conifer Callitropsis nootkatensis (Cupressaceae)

Microsatellite primers were developed for Nootka cypress ( Callitropsis nootkatensis ) to provide quantitative measures for gene conservation that can assist in guiding management decisions for a species experiencing climate-induced decline.

Applications in Plant Sciences

Compatible management of red alder-conifer ecosystems in southeastern Alaska.

Forest clearcutting has been the primary timber management practice in forests of southeastern Alaska since commercial timber harvesting began in the 1950s, and the dense, even-aged conifer stands that subsequently developed have broad and undesirable consequences for some nontimber resources-most notably, fish and wildlife. Because a few earlier reports suggested that...

Wood formation from the base to the crown in Pinus radiata: gradients of tracheid wall thickness, wood density, radial growth rate and gene expression

Wood formation was investigated at five heights along the bole for two unrelated trees of Pinus radiataBoth trees showed clear gradients in wood properties from the base to the crown. Cambial cells at the base of the tree were dividing 3.3-fold slower than those at the crown, while the average thickness of cell walls in wood was highest at the base....

Cross-species transferability and mapping of genomic and cDNA SSRs in pines

Two unigene datasets of Pinus taeda and Pinus pinaster were screened to detect di-, tri and tetranucleotide repeated motifs using the SSRIT script. A total of 419 simple sequence repeats (SSRs) were identified, from which only 12.8% overlapped between the two sets. The position of the SSRs within the coding sequence were predicted...

Imputing forest structure attributes from stand inventory and remotely sensed data in western Oregon, USA

Imputation is commonly used to assign reference stand observations to target stands based on covariate relationships to remotely sensed data to assign inventory attributes across the entire landscape. However, most remotely sensed data are collected at higher resolution than the stand inventory data often used by operational foresters. Our primary goal was to compare...

Microsatellites for Lindera species

Microsatellite markers were developed for conservation genetic studies of Lindera melissifolia (pondberry), a federally endangered shrub of southern bottomland ecosystems. Microsatellite sequences were obtained from DNA libraries that were enriched for the (AC)_n simple sequence repeat motif. From 35 clone sequences, 20 primer...

Use of molecular genetic markers in forest management

When managing forests for biodiversity or sustainability, attention must be given to how silvicultural practices affect genetic diversity. A new generation of DNA-based markers affords a greater detail of genetic analysis than previously possible. These new markers, SSRs or microsatellites, have been used to demonstrate genetic diversity and infer evolutionary history...

Participatory genetic improvement: longleaf pine

University-industry-state cooperative tree improvement has been highly successful in the southern United States. Over nearly 60 years, three cooperative programs have led the way in developing and deploying genetically improved planting stocks for loblolly (Pinus taeda L.) and slash (P. elliottii Engelm.) pines. However, much lower levels of success have been achieved...

Evidence and implications of recent and projected climate change in Alaska's forest ecosystems

The structure and function of Alaska's forests have changed significantly in response to a changing climate, including alterations in species composition and climate feedbacks (e.g., carbon, radiation budgets) that have important regional societal consequences and human feedbacks to forest ecosystems. In this paper we present the first comprehensive synthesis of...

A study of the early fruit characteristics of pondberry

Pondberry [Lindera melissifolia (Walt.) Blume] is an endangered, dioecious, clonal shrub that grows in forested wetlands in the Southeastern United States. Because pondberry is endangered, presence of this plant could limit silvicultural options available to managers of public lands. Interest in pondberry has focused on the clonal nature of this...
