Mathematics, Physics, and Computer Science Faculty Articles and Research

Light Detection and Ranging (LiDAR) systems can be used to estimate both vertical and horizontal forest structure. Woody components, the leaves of trees and the understory can be described with high precision, using geo-registered 3D-points. Based on this concept, the Effective Plant Area Indices (PAIe) for areas of Korean Pine (Pinus koraiensis), Japanese Larch (Larix leptolepis) and Oak (Quercus spp.) were estimated by calculating the ratio of intercepted and incident LIDAR laser rays for the canopies of the three forest types. Initially, the canopy gap fraction (GLiDAR) was generated by extracting the LiDAR data reflected from the canopy surface, or …

Relationship Of Climate And Growth Of Quaking Aspen (Populus Tremuloides) In Yellowstone National Park, Erik S. Jules, Allyson L. Carroll, Matthew J. Kauffman

Aspen Bibliography

Quaking aspen is a widespread tree that is in decline across wide areas of western North America, and is predicted to experience a large range shift if future climate predictions are realized. The purpose of our study was to determine what climate factors have influenced aspen growth in Yellowstone National Park, USA, and to determine whether these climatic influences vary across a heterogeneous landscape. We extracted increment cores from 10-12 aspen in each of 16 stands spread across a 1,526 km2 area. Using ring widths, we created a182-year standardized chronology from 1821 to 2003 A.D. composed of 151 series. We …

Turkish Journal of Agriculture and Forestry

Developing successful strategies to ensure future increase in yield of soybean and peanut crops hinges in part, on improving the genetic basis of the cultivars. Knowledge of genetic relationships in crop breeding programs provides valuable information that can be used by plant breeders as a parental line selection tool. So far, a thorough analysis of genetic diversity among the soybean and peanut genotypes grown in Turkey had not been attempted at DNA level. In this study, inter-simple sequence repeats (ISSR) and sequence-related amplified polymorphism (SRAP) markers were used to evaluate the genetic diversity between 21 soybean and 32 peanut cultivars …

Zinc Alleviates Salt Stress And Increases Antioxidant Enzyme Activity In The Leaves Of Pistachio (Pistacia Vera L. ‘Badami’) Seedlings, Vahid Tavallali, Majid Rahemi, Saeed Eshghi, Bahman Kholdebarin, Asghar Ramezanian

Turkish Journal of Agriculture and Forestry

The mechanism(s) by which Zn alleviates NaCl stress was investigated in Pistacia vera L. 'Badami'. Pistachio seedlings were treated with 0, 800, 1600, 2400, and 3200 mg of NaCl kg^{-1} of soil, along with Zn (0, 5, 10, and 20 mg kg^{-1} of soil). NaCl stress induced high oxidative stress, increasing lipid peroxidation, electrolyte leakage, and lipoxygenase (LOX, E.C. 1.13.11.12) activity to high levels. Zn supplement efficiently reduced all these adverse effects of salt stress. However, there were no significant differences among the above parameters in plants treated with Zn only. NaCl stress significantly increased the activity of antioxidant enzymes. …

Turkish Journal of Agriculture and Forestry

Polygalacturonase-inhibiting proteins (PGIP) play important roles in the defense against plant pathogens, especially fungi. The sequence of strawberry PGIP gene was obtained using reverse transcription PCR (RT-PCR) and its expression in different tissues was studied by semi-quantitative RT-PCR. A cDNA fragment of FaPGIP gene was cloned and the sequence analysis shows that the fragment contains a full ORF of 999 bp encoding 332 amino acids. The FaPGIP gene from genomic DNA shows a single 168bp intron that is efficiently spliced out of the FaPGIP pre-mRNA transcript. The FaPGIP has a high degree of identity with previously isolated PGIP genes and …

Back To Nature: Ecological Genomics Of Loblolly Pine (Pinus Taeda, Pinaceae), Andrew J. Eckert, Andrew D. Bower, Santiago C. González-Martínez, Jill L. Wegrzyn, Graham Coop, David B. Neale

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Genetic variation is often arrayed in latitudinal or altitudinal clines, reflecting either adaptation along environmental gradients, migratory routes, or both. For forest trees, climate is one of the most important drivers of adaptive phenotypic traits. Correlations of single and multilocus genotypes with environmental gradients have been identified for a variety of forest trees. These correlations are interpreted normally as evidence of natural selection. Here, we use a genome-wide dataset of single nucleotide polymorphisms (SNPs) typed from 1730 loci in 682 loblolly pine (Pinus taeda L.) trees sampled from 54 local populations covering the full-range of the species to examine …

Population Trends In Northern Spotted Owls: Associations With Climate In The Pacific Northwest, Elizabeth M. Glenn, Robert G. Anthony, Eric D. Forsman

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

We used reverse time capture-mark-recapture models to describe associations between rate of population change (λ) and climate for northern spotted owls (Strix occidentalis caurina) at six long-term study areas in Washington and Oregon, USA. Populations in three of six areas showed strong evidence of declining populations, while populations in two additional areas were likely declining as well. At four areas, λ was positively associated with wetter-than-normal conditions during the growing season, which likely affects prey availability. Lambda was also negatively associated with cold, wet winters and nesting seasons, and the number of hot summer days. The …
