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. …

Cloning, Characterization, And Expression Of The Gene Encoding Polygalacturonase- Inhibiting Proteins From Strawberry, Yong Zhang, Hao-Ru Tang, Yan-Xia Hou, Hao Jiang, Ya Luo, Jie Zhang

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 …

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 …

Managing The National Forests Through Place-Based Legislation, Martin Nie, Michael Fiebig

Society and Conservation Faculty Publications

The resolution of multiple use conflicts through place-based (national forest-specific) legislation has recently received increased interest. Most of these proposals combine wilderness designation, restoration objectives, economic development, funding arrangements, and other provisions, in a conservation package to be considered by Congress. Interest in the place-based legislative approach is precipitated by numerous factors, including perceptions of agency gridlock, problems related to forest planning, unresolved roadless and wilderness issues, and the embrace of collaboration. Though the national forests have a more unified governing framework than other federal land systems, the U.S. Forest Service has implemented place-based legislation in a few cases. This …

Stand Conditions Immediately Following A Restoration Harvest In An Old-Growth Pine-Hardwood Remnant, Don C. Bragg

Journal of the Arkansas Academy of Science

Portions of the Levi Wilcoxon Demonstration Forest (LWDF), a privately owned parcel of old growth pine and hardwoods in Ashley County, Arkansas, were recently treated to restore conditions similar to some historic accounts of the virgin forest. Following a hardwood-only cut, a post-harvest inventory showed that the number of tree species in the sample area declined from 24 in 2006 (the most recent pre-harvest inventory) to 12 in 2009. Loblolly (Pinus taeda L.) and shortleaf (Pinus echinata Mill.) pine now comprise 59.2% of the remaining live trees, up from 16.2% in 2006. Between 2006 and 2009, basal area dropped from …

Turkish Journal of Agriculture and Forestry

Temperature and rainfall changes are both significant components of climate change. This study characterizes the effects of climate change on water resources in the Büyük Menderes river basin in western Turkey, based on hydrology, temperature, and rainfall data from the past 45 years (1963-2007). When analyzed with the Mann-Whitney test, the temperature and precipitation time series exhibited obvious step changes with a 5% level of significance. Both the parametric t-test and nonparametric Mann-Kendall statistical test results showed an increasing trend of the temperature. Over the past 45 years, the temperature increased just about 1 °C. The long-term trend of annual …

Effects Of Sugar Feeding On Lipid, Glycogen, And Total Sugar Levels Of A Female Parasitoid, Bracon Hebetor (Say) (Hymenoptera: Braconidae), Eylem Akman Gündüz, Adem Gülel, Özgür Varer Işitan, Ali̇ Boz, Özlem Cesur

Turkish Journal of Agriculture and Forestry

The goal of this study was to compare the lipid, glycogen, and total sugar levels in completely starved (no water or sugar provided), honey-fed, sucrose-fed, or sugar-starved (only water provided) females of the parasitoid Bracon hebetor (Say) (Hymenoptera: Braconidae). We also quantified the lipid, glycogen, and total sugar levels in newly emerged unfed (day 0) female (n = 30) wasps. The mean amounts of reserves obtained from these females were regarded as a standard for the initial amount of reserves. The glycogen level of emerging females was 17.99 ± 2.02 \mug. As expected, sucrose- or honey-fed females had significantly higher …
