Asserting Indigenous Identity To Substantiate Customary Forest Claims: A Case Study Of The Dayaks Of West Kalimantan, Indonesia, Charlotte Reinnoldt

CMC Senior Theses

This thesis examines Dayak identity constructions and how they have been and are currently being used to assert customary land rights in forested areas of West Kalimantan, Indonesia. The Indonesian state has required that customary land claims include proof that communities have maintained their indigenous institutions. Drawing from government and NGO reports, academic research, and Indonesian law, a few questions thus are explored: What aspects of identity must be maintained in order to be sufficient to claim customary land rights under Indonesian law? How has recent Dayak mobilization fed into a resurgence in Dayak identity and pride, and vice versa? …

Comparative Transcriptome Sequencing To Determine Genes Related To The Nucellar Embryony Mechanism In Citrus, Özhan Şi̇mşek, Di̇cle Dönmez, Si̇nan Eti̇, Turgut Yeşi̇loğlu, Yildiz Kaçar

Turkish Journal of Agriculture and Forestry

Several citrus varieties produce apomictic seeds by the nucellar embryony (NE) mechanism. Nucellar embryos are created from nucellus tissue and have an identical genetic constitution to the mother plant. Nucellar embryony is known to be an unusual feature of seed production in many citrus cultivars. The term "NE" refers to the development of identical embryos from the maternal tissue known as the nucellus surrounding the embryo sac. The authors aimed here to detect differentially expressed genes involved in the NE mechanism. Orlando tangelo (OT), producing apomictic seeds, and a clementine mandarin, Algerian tangerine ranch selection (AT), known as monoembryonic, were …

Genome-Wide Identification And Molecular Characterization Of Citrus Unshiu Wrkytranscription Factors In Satsuma Mandarin: Clues For Putative Involvement In Cell Growth,Fruit Ripening, And Stress Response, Mariem Ayadi, Rim Mzid, Rayda Ben Ayed, Najla Kharrat, Henda Merchaoui, Ahmed Rebai, Mohsen Hanana

Turkish Journal of Agriculture and Forestry

WRKY transcription factors, being involved in several biological roles, stimulus signaling, and stress response, could be interesting candidates to prospect, particularly in the Citrus unshiu (Satsuma mandarin) genome. Our approach, mainly based on computational analyses, led to the identification of 51 CiuWRKYs followed by their molecular characterization. Syntenic relationship analysis showed significant bias towards sweet orange and Arabidopsis chromosomes. Analyses of promoter region showed that CiuWRKY1 modulates gene transcription through W-box site targeting. The deduced CiuWRKY1 protein was moderately hydrophobic. A comparative in silico analysis among Arabidopsis thaliana and Citrus sinensis WRKYs allowed us to designate orthologous genes. Lacking available …

Turkish Journal of Agriculture and Forestry

In this research, the effects of rootstocks on the storage performance of Nova mandarins grafted on Carrizo citrange, Troyer citrange, or sour orange grown in the ecological conditions of Dörtyol were studied. Fruits were harvested at optimum maturity and kept at 4 °C and 6 °C for 120 days. Changes in weight loss, incidence of fungal decay and physiological disorders, juice content, total soluble solids (TSS), percent fruit with green button, titratable acidity (TA), juice pH, vitamin C content, and rind color (L*, C*, h°) were monitored at 15-day intervals during storage to determine the effects of rootstock on postharvest …

The Development Of A Low Cost Uav-Based Image Acquisition System And The Procedure For Capturing Data In Precision Agriculture, Ari̇f Behi̇ç Teki̇n, Marco Fornale

Turkish Journal of Agriculture and Forestry

Remote sensing is a method of monitoring the natural heterogeneity of vegetation. Although satellite based remote sensing has been a popular method for monitoring the earth's surface, it has several drawbacks, such as the orbital period, unattended capture, and investment cost. On the other hand, an unmanned air vehicle (UAV) is more flexible in terms of deployment, monitoring a small area, and being easy to obtain at a low cost. From this point of view, the goal of this research was to develop a low cost and easy to implement technical solution for mapping spatial heterogeneity and research its relationship …

Effects Of Cooking And Extra Virgin Olive Oil Addition On Bioaccessibility Of Carotenes Intomato Sauce, Merve Tomaş, Osman Sağdiç, Gi̇zem Çatalkaya, Derya Kahveci̇ Karincaoğlu, Esra Çapanoğlu Güven

Turkish Journal of Agriculture and Forestry

In this study, the effects of cooking and the addition of extra virgin olive oil on the in vitro bioaccessibility of carotenoids in tomato sauce were evaluated. The results indicated that total antioxidant activity, α-tocopherol, lycopene, β-carotene, lutein, and chlorophyll a contents were positively affected by the combination of cooking and addition of extra virgin olive oil. Moreover, after in vitro digestion, for intestinal phase, lycopene and Β-carotene were observed in all samples, whereas α-tocopherol and chlorophyll a were not detected in any of the samples. Lycopene (≈8.5-fold) and β -carotene (≈5-fold) were significantly improved (P < 0.05) by the effect of cooking and addition of extra virgin olive oil to the samples compared to control tomato sauce (without oil and cooking).

The Influence Of Exogenous Capsaicin Application On The Germination, Seedling Growth,And Yield Of Pepper, Levent Arin, Çağatay Arabaci

Turkish Journal of Agriculture and Forestry

The aim of this research was to investigate the effect of capsaicin application in different doses (0.0, 0.1, 1.0, 10.0, 25.0, 50.0, 100.0, and 200.0 ppm) on the germination, seedling growth, and yield of pepper plants (Capsicum annuum L. 'Burdem'). For this purpose, capsaicin was applied at several stages: (i) to the pepper seed before sowing, (ii) to the leaves during the 3rd to 4th true leaf stage for seedling quality evaluation, and (iii) to the leaves before planting in a greenhouse. There were no statistical differences among capsaicin doses and the control with respect to germination and emergence, but …

Island Invasion: The Silent Crisis In Hawaii, Sophia Janssen

Pomona Senior Theses

Keeping out invasive species may, upon first review, seem like a trivial environmental cry from ecologists and deep environmentalists; a belated wish to return to an undeveloped world where nature was pristine. However invasive species create problems that impact all of us and can have far more severe consequences than changing a stunning landscape. These problems are heightened in islands like Hawaii, where the fragile ecosystems have developed over centuries of evolution and adaptation. The introduction of a disease-carrying mosquito can put the people of Hawaii at risk to many vector-born illnesses and create an epidemic, taking human life. The …

Northern Hardwood Silviculture: Preferences Among Family Forest Owners In The Western Upper Peninsula Of Michigan, Alexander C. Helman

Dissertations, Master's Theses and Master's Reports

In the northern hardwood forests of the Western Upper Peninsula of Michigan, single-tree selection is the most commonly used silvicultural system. This system provides both a sustained yield of timber and attempts to emulate the windfall disturbance regime that determines the uneven aged structure of northern hardwood forests. However, with concerns about tree species diversity loss and a lack of early successional forests, even-aged regeneration methods are likely to become an increasingly crucial tool in the toolbox for managing northern hardwood forests of the Lake States. The forests of the Western Upper Peninsula are comprised of a mosaic of ownerships, …

Assessing Soil Compaction Following A Winter Timber Harvest In The Western Upper Peninsula Of Michigan, Rafia Rahman

Dissertations, Master's Theses and Master's Reports

Harvesting during winter is encouraged as a best management practice to protect soil during logging operations. The western Upper Peninsula of Michigan typically experiences early and persistent snowfall, which insulates the forest floor and prevents soils from freezing. The objective of this study is to assess the effects of slash volume, snow depth, overstory treatment, and machine traffic intensity on soil bulk density following a winter harvest of a northern hardwood forest on cobbly silt-loam soils. The harvest was conducted at the Ford Forest in Alberta, Michigan using cut-to-length harvest systems (i.e. harvester and forwarder) during which the soil remained …

The Impact Of Prescribed Fire On Moth Assemblages In The Boston Mountains And Ozark Highlands, In Arkansas, Erin E. Guerra, Cristina M. Blanco, Jorista Garrie

Journal of the Arkansas Academy of Science

In addition to the impacts of prescribed fires on forest vegetation, this ecosystem process also has dramatic impacts on associated insect assemblages. For herbivorous, terrestrial insects, fire predictably results in a cycle of initial insect population reduction followed by recovery and growth, in which these insect populations exceed pre-fire abundances. We sought to examine if fire-induced disturbance cycles make prescribed burned areas more or less suitable specifically for moths (order Lepidoptera), which is a major food source for, among others, multiple bat species. We surveyed moth assemblages at 20 burned and 20 unburned sites in the Boston Mountain and Ozark …

Effects Of Depth-Dependent Irrigation Regimes And Organomineral Fertilizers On Water Useand Quality Attributes Of Sugar Beet, Ali̇ Ünlükara

Turkish Journal of Agriculture and Forestry

Experiments were conducted under provincial conditions of Kayseri, Turkey, for two years in the growing seasons of 2014 and 2015 to determine the effects of irrigation water applications based on different sugar beet root zone depths and different organomineral fertilizers on sugar beet yield, root quality, water consumption, and water use efficiency. Two constant root depths (D1 = 0.9 m and D2 = 0.6 m) and one active water extraction root depth (D3= 0.4-0.9 m) were investigated. A mineral fertilizer (F1), an organomineral fertilizer (F2), and organic + mineral fertilizer (F3) were considered as the subtreatments in the experiments carried …

Utilization Of Sucrose During Cocultivation Positively Affects Agrobacterium-Mediatedtransformation Efficiency In Sugar Beet (Beta Vulgaris L.), Songül Gürel, Muhammet Çağri Oğuz, Ferzat Turan, Kemal Kazan, Canan Yüksel Özmen, Ekrem Gürel, Ali̇ Ergül

Turkish Journal of Agriculture and Forestry

Sugar beet (Beta vulgaris L.) is one of the most important industrial crops throughout world. With the availability of suitable genetic transformation technologies, the yield, quality, and stress tolerance of sugar beet could be improved significantly. However, low transformation efficiencies seriously limit the application of molecular technologies to the genetic improvement of sugar beet. With the aim of improving gene transfer techniques for sugar beet, the effect of different sucrose concentrations during cocultivation on the initial Agrobacterium-mediated transformation efficiencies in sugar beet was tested. To develop an efficient experimental system through which the effect of sucrose could be tested, first, …

Deciphering Global Dna Variations And Embryo Sac Fertility In Autotetraploid Rice Line, Fozia Ghouri, Jiani Zhu, Hang Yu, Jinwen Wu, Faheem Shahzad Baloch, Xiangdong Liu, Muhammad Qasim Shahid

Turkish Journal of Agriculture and Forestry

Autotetraploid rice is a new germplasm resource obtained by doubling chromosomes through colchicine treatment. There have been many studies on the reproductive characteristics of autotetraploid rice, but little is known about global DNA variations and reasons for low embryo sac fertility in autotetraploid rice. Therefore, an autotetraploid rice line (T446) was used for resequencing and embryo sac fertility was observed. Whole-genome resequencing data revealed 87,229 SNPs and 11,022 InDels in the genome of T446 versus E246 (diploid rice), which had an average of 23.37 SNPs and 2.95 InDels per 100 kb. A total of 17,375 and 17,171 structural variations and …

Long-Term Effectiveness Of Fuel Treatments In Oak And Chaparral Stands Of Northern California, Caroline Ann Martorano

Cal Poly Humboldt theses and projects

Fuel reduction treatments are broadly implemented to reduce the risk of extreme wildfire. Yet, research on the long-term effectiveness and ecological consequences among these treatments is lacking. In this study, I examined short- and long-term changes in fuels and understory vegetation after treatment in chaparral and oak-dominated stands of Whiskeytown National Recreation Area. Treatments included mastication and spring burning, spring burning only, mastication only, and hand-thinning. Treatments were applied randomly to 1 to 2 units within each of 10 blocks. Two plots were established in each treatment unit and fuel and vegetation data was collected and analyzed at the block …

Estimating The Present Value Of Carbon Sequestration In U.S. Forests, 2015–2050, For Evaluating Federal Climate Change Mitigation Policies, Robert T. Haight, Randall Bluffstone, Jeffrey D. Kline, John D. Coulston, David N. Wear, Kate Zook

Economics Faculty Publications and Presentations

We demonstrate an application evaluating carbon sequestration benefits from federal policy alternatives. Using detailed forest inventory data, we projected carbon sequestration outcomes in the coterminous 48 states for a baseline scenario and three policy scenarios through 2050. Alternatives included (1) reducing deforestation from development, (2) afforestation in the eastern United States and reforestation in the western United States, and (3) reducing stand-replacing wildfires. We used social cost of carbon estimates to evaluate the present value of carbon sequestration benefits gained with each policy. Results suggest that afforestation and reforestation would provide the greatest marginal increase in carbon benefit, far exceeding …

Identifying An Optimal Bald Eagle Monitoring Program For Southwest Alaska National Parks, Rebecca Kolstrom

Electronic Theses and Dissertations

The Southwest Alaska Inventory and Monitoring Network includes bald eagle monitoring as part of their Vital Signs Monitoring Plan. Lake Clark National Park and Preserve, Katmai National Park and Preserve, Kenai Fjords National Park, and Wrangell – St. Elias National Park and Preserve monitor bald eagles annually, albeit slightly differently among parks. Since monitoring decisions involve multiple objectives and stakeholders, there was a need for a structured approach to identify an optimal monitoring program. We used a structured decision making process and an iterative, four-round Delphi Process to collect information about long-term bald eagle monitoring from experts. We collected information …
