Understanding plant drought responses is crucial for effective afforestation in drylands. This study aimed to investigate the effects of irrigation (31.25 mm seedling–1 every 45 days) on the early survival and growth of 3-month-old Haloxylon ammodendron seedlings at an afforestation site established in Tajikistan in 2021. In July 2022 and June 2023, surveys were conducted to compare seedling survival rates, height, root collar diameter (RCD), stem volume per unit area, and height-to-RCD ratio between irrigation (IR) and nonirrigation (NIR) treatments. The IR treatment increased survival rates in 2022 but not in 2023. By 2023, the IR treatment had increased the …
Adapting To Climate Change In Semiarid Regions Via Conservation Measures: Climate-Smart Crop Rotations Of Food Legumes In Cool Seasons, Velibor Spalevic, Mohsen Janmohammadi, Naser Sabaghnia, Shuraik Kader
Turkish Journal of Agriculture and Forestry
The high potential of evapotranspiration, unsuitable soil conditions, irregular distribution of rainfall, and ineffective techniques of soil moisture conservation are among the limitations of semiarid regions of Central and West Asia and North Africa (CWANA), and they have intensified during recent decades with climate change. CWANA’s agroecosystems are fragile and highly vulnerable to the consequences of global warming and aggravation of water scarcity, and need to redefine agroclimatic zoning. Winter cereals are the predominant crops in the region of CWANA. The highest amount of cultivation is allocated to societies with dominant rainfed agriculture, which is often not economically profitable. The …

Turkish Journal of Agriculture and Forestry
The mango (Mangifera indica L.) fruit is globally relished for its sweet taste, unique aromatic profile, and enriched nutritional value. However, its short postharvest life is a serious challenge for export to long-distance markets. 1-Methylcyclopropene (1-MCP) is an ethylene inhibitor known to delay ripening in many fruits, including mango. However, comparative research suggesting an appropriate method to treat mangoes with 1-MCP is limited. In this study, mango fruit cv. Sufaid Chaunsa were fumigated with 0.25 ppm 1-MCP or treated aqueously with 1.2 ppm 1-MCP for 5 min and then packed in modified atmosphere packaging (MAP). The control fruits were not …

Life After Death: Investigating The Resistance And Recovery Of Fungal Communities To Foundation Tree Mortality, Jessie F. Marlenee
Biology ETDs
Tree mortality can have cascading effects on the composition and resilience of interacting fungal communities. Yet, little is known about the impact tree mortality, distinct from abiotic drivers (i.e., drought), has on these communities. This dissertation focuses on the resilience of fungal communities to experimental tree mortality in a piñon-juniper woodland. In chapter one, I found that piñon mortality reduced piñon fine root biomass and piñon mycorrhizal fungal diversity, whereas juniper mycorrhizal fungi were unaffected by juniper mortality. In chapter two, I revealed that piñon mortality altered the composition and spatial structure of mycorrhizal and saprotrophic fungi in the soil, …

The extent and distribution of tropical peatlands, and their importance as a vulnerable carbon (C) store, remain poorly quantified. Although large peatland complexes in Peru, the Congo basin, and Southeast Asia have been mapped in detail, information on many other tropical areas is uncertain. In the Eastern Colombian lowlands, peatland area estimates range from 700 km2 to nearly 60,000 km2, leading to highly uncertain C stocks. Using new field data, high-resolution Earth observation (EO), and a random forest approach, we mapped peatlands across Colombian territory East of the Andes below 400 m elevation. We estimated peatland extent using two approaches: …

Climate change may transform peatlands from net carbon (C) sinks to C sources, which could result in a positive feedback to global warming. Warmer temperatures might lower water tables, increase the abundance of shrubs, slow Sphagnum and sedge growth and further accelerate the decomposition of dissolved organic matter (DOM) with a concomitant release of C from the surface. Studies in which vascular plant functional groups (PFGs) in peatlands have been manipulated to mimic the potential effects of a warming climate on DOM are scarce. In the subject study, seasonal effects of PFGs on the molecular composition of DOM of peat …

The application of noninvasive genetic methods toward the field of conservation has increased our understanding of many wildlife populations that are difficult to sample, allowing for better management. In molecular ecology, the use of noninvasive sampling became widely feasible with the advent of microsatellites, a highly polymorphic, short-length marker that could be genotyped from low-quality DNA sources. Despite decades of use, many microsatellite panels continue to suffer from high genotyping error rates, allelic dropout, and limited reproducibility across laboratories. To address these issues, single nucleotide polymorphisms (SNPs) offer advantages such as lower genotyping error rates, avoidance of allelic dropout due …

Aspen Bibliography
Quaking aspen (Populus tremuloides) is a widely distributed species in the western United States, but in the northern Rocky Mountain Region it is a rare forest component. In national forests (NF) of the northern Rocky Mountain Region this species comprises only 1% of the Bighorn, 3% of the Black Hills, and 1% of the Shoshone cover types (DeBlander 2002, Menlove 2008, Witt 2008). Since aspen forests provide increased species richness, support wildlife, are an important component of watersheds, and have aesthetic value, there are concerns regarding the health of this relatively rare forest cover type.

Small mustelids are difficult to survey due to their low density and cryptic nature. Population status of North American weasels (Mustela erminea, Mustela nivalis, and Neogale frenata) are believed to be in decline, but there are no standardized monitoring protocols to evaluate their status. To support weasel monitoring, we compared the attractiveness of various combinations of baits and lures to weasels in sites located throughout the eastern and central USA. We baited a total of 122 clusters of 4 camera traps, across 14 states, with random combinations of 4 baits and 3 scent lures in the winters of 2022 and …
