Senescent Trees Stabilize Aboveground Wood Net Primary Production Immediately After Disturbance, Maxim S. Grigri
Theses and Dissertations
In the United States, forests sequester 17% of national carbon (C) emissions annually (UGCRP, 2018), however shifting forest disturbances threaten the stability of this essential C sink. Unlike the high severity, stand-replacing disturbances that were widespread a century ago, today’s eastern temperate forests experience frequent low-to-moderate severity disturbances from invasive pests and pathogens with mixed effects on net primary production (NPP). Carbon cycling stability after disturbance has been reported, however, the mechanisms underlying immediate NPP stability or decline are not well understood. Through weekly measurements of production in a landscape scale experiment, we show that the sustained growth of senescent …

Interspecific Gene Flow Potentiates Adaptive Evolution In A Hybrid Zone Formed Between Pinus Strobiformis And Pinus Flexilis, Mitra Menon
Theses and Dissertations
Species range margins are often characterised by high degrees of habitat fragmentation resulting in low genetic diversity and higher gene flow from populations at the core of the species range. Interspecific gene flow from a closely related species with abutting range margins can increase standing genetic diversity and generate novel allelic combinations thereby alleviating limits to adaptive evolution in range margin populations. Hybridization driven interspecific gene flow has played a key role in the demographic history of several conifer due to their life history characteristics such as weak crossability barriers and long generation times. Nevertheless, demonstrating whether introgression is adaptive …

Efficacy Of Forest Restoration Treatments Across A 40-Year Chronosequence At Redwood National Park, Kevin Soland
Cal Poly Humboldt theses and projects
Following 20th century logging, much of the natural coast redwood (Sequoia sempervirens) range consists of dense second-growth stands with slow tree growth and low biodiversity. There is a landscape-scale effort in much of coastal northern California to increase tree growth rates and ecosystem biodiversity via thinning treatments, thereby hopefully accelerating the development of old-growth forest characteristics. Redwood National Park (RNP) has been experimenting with thinning in these forest types since the 1970s. Given the interesting history of logging and restoration in RNP and the future plans for widespread thinning in this region, my thesis examined the effects …

Alternative Water Sources In Western Conifers Via Foliar Uptake And Hydraulic Redistribution, Ariel Sol Weisgrau
Cal Poly Humboldt theses and projects
Water is often the most limiting resource in a plant’s environment. Plants that can maximize their ability to acquire water improve their chances of success. Outside of the traditional soil-plant-atmosphere continuum, plants can alternatively acquire water via foliar uptake of water and hydraulic redistribution (HR) of deep water. This study used greenhouse-based experiments to investigate water use and physiology in four conifer species native to the western U.S.: Picea sitchensis (Bong.) Carriére (PISI), Pseudotsuga menziesii (Mirb.) Franco (PSME), Sequoia sempervirens (D. Don) Endl. (SESE), and Thuja plicata Donn ex. D. Don (THPL). First, this work investigated the capacity for foliar …

The Potential Role Of Payment For Ecosystem Services In Protected Area Management In Rwanda: A Case Study From Gishwati-Mukura National Park, Yves Gakunde
Antioch University Dissertations & Theses
The demand for ecosystem services (ES) by communities around the world especially from developing countries is increasing, and creates conflict between protected ecosystem management and community socioeconomic wellbeing needs, particularly around protected areas. Taking into consideration globalization, capitalism, weak policies, and population growth as some of the majors driving factors to land change, increased demand for ES comes in part from societies’ changing economic demands and opportunities, such as food and commercial crop production, timber extraction, urbanization, and infrastructural development. Many biodiversity conservation approaches and initiatives have been used to protect and maintain healthy ecosystems. While the fence and fine …

The Effects Of Wheatgrass Length On Antioxidant Activity And Total Phenolic Content Inwheatgrass (Triticum Spp.), Yusuf Şavşatli
Turkish Journal of Agriculture and Forestry
This study was carried out with the aim of determining the effects of wheatgrass lengths on antioxidant activity and total phenolic content of wheatgrass belonging to different cultivars (Triticum spp.) in laboratory conditions in 2017. When the wheat seedlings grown in plastic containers under soilless conditions reached three levels of wheatgrass length (5-6, 8-9, and 11-12 cm), the seedlings were cut from the root collar and dried in an oven. As a result of analysis of the dried material, it was found that the cut lengths of wheatgrass significantly (P < 0.01) affected antioxidant activity and total phenolic content of wheatgrass. Ten wheat cultivars belonging to Triticum monococcum L., T. durum L., and T. aestivum L. were used. Wheatgrass was cut at three lengths (5-6, 8-9, and 11-12 cm). It was found that the wheatgrass lengths had a significant (P < 0.01) effect on antioxidant and total phenolic content of wheatgrass. In addition, in terms of these traits, the most suitable wheatgrass length for cutting changed depending on the wheat species and also cultivars. The highest (P < 0.01) antioxidant activity and total phenolic content (TPC) were also determined at three wheatgrass lengths in cultivar Sarıbaşak. The average values obtained from Sarıbaşak wheatgrass were 31.0% for DPPH-free radical scavenging activity and 51.6 mg GAE-1 dry weight for TPC. The results of the analysis suggested that Sarıbaşak is the most promising cultivar in terms of both antioxidant activity and TPC in wheatgrass.
