Postharvest Application Of 1-Methylcyclopropene And Modified Atmosphere Packaging Extends Shelf Life And Maintains Eating Quality Of Mango Fruit Cv. Sufaid Chaunsa, Hafiz Muhammad Usman, Sajid Hussain, Raheel Anwar, Ahmad Sattar Khan, Aman Ullah Malik, Muhammad Moaaz Ali, Khurram Ziaf, Arooba Abbas
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 …
Effect Of Eco-Friendly Fertilizers And Edible Coatings On Fatty Acids And Phenolics In Fresh-Cut Melon During Cold Storage, Firat İşlek
Turkish Journal of Agriculture and Forestry
The demand for convenient and ready-to-eat food has increased, including fresh-cut fruit and vegetables. At the same time, people are also becoming more health-conscious and are aware of the positive impact of healthy food choices on their well-being. For this reason, it is important to deliver fruits and vegetables to people’s tables using both environmentally and human-friendly practices, from cultivation to postharvest storage. In the current study, in order to support agricultural sustainability, humic acid, liquid vermi¬compost, and organomineral fertilizers that do not pose a risk to human health or the environment were used in melon. Furthermore, several edible coverings …

Our study investigated the performance of various maize hybrids across diverse environments and planting densities, with the aim of understanding the complex interaction between genotypes, environmental conditions, and planting practices. A set of 13 experimental maize hybrids and two commercial check hybrids was tested over a 3-year period at eight different locations and under two distinct plant densities using a split-plot design. The results revealed significant variations in grain yield (GY) among hybrids across different environments, suggesting a substantial genotype-by-environment (G × E) interaction effect, particularly of the crossover type. This variability was attributed to fluctuations in environmental factors such …

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: …
Life After Death: Investigating The Resistance And Recovery Of Fungal Communities To Foundation Tree Mortality, Jessie F. Marlenee
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, …

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 …

How The Biotic And Abiotic Factors In The Belle Forest Cave And Arboretum Soil Dictates Tree Species Prevalence, Amya A. Bingham
SPARK Symposium Presentations
A plethora of factors in the soil impact a plant’s health, including the presence of different biotic and abiotic factors. These include things like temperature, elevation, pH, microbial respiration and the presence of water, clay, loam, silt, sand, nitrogen, potassium, and phosphorus. Different soils will have varying amounts of these, which may dictate what is able to grow in them, and therefore also the surrounding area. This research project explores how the aforementioned biotic and abiotic factors affect the soil at the Belle Forest Cave and Arboretum. Three samples will be taken from four spots along a transect at this …

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 Health On National Forests In The Northern Rocky Mountain Region (2008/2009 To 2024), James T. Blodgett, Kurt K. Allen, Megan Wilson, Bradley Lalande
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.

Rheological, Interfacial, And Filtration Behavior Of Lignocellulosic Nanomaterials In Suspension And Emulsion Drilling Fluids, Meen Sung Koo
LSU Doctoral Dissertations
In recent years, the rheological aspects of suspensions/emulsions applied by cellulose nanomaterials (CNMs) have been gained considerable interests due to high gel-forming properties ascribed by hydrophilicity, crystallinity, ease functionalization, and high aspect ratio. Introducing residual lignin in CNMs (LCNMs) seemed to be capable of achieving various advantages in the application of CNMs ascribed by hydrophobicity, binding effects, and abundant aromatic groups derived from complexity of lignin. This dissertation dedicates to the characterizations of (L)CNMs, and rheological properties of (L)CNMs applied fluids (i.e., suspension and emulsion). In the suspension system, the presence of lignin in LCNMs decreased gel strength, viscosity, and …

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 …

Aspen Bibliography
Because temperature has pervasive effects on biological rates, climate warming may alter the outcomes of interactions between insect hosts and their parasitoids, which, for many host species, constitute the single largest source of mortality. Despite growing interest in parasitoid-host responses due to climate change, there are few empirical tests of thermal tolerance differences between non-model lepidopteran hosts and their parasitoids and almost none from mountain ecosystems where warming is occurring more rapidly. We examined the thermal ecology of a host–parasitoid interaction in the Rocky Mountains using the wild populations of the aspen leaf miner (Phyllocnistis populiella) and a …

Neodothiora populina is a black yeast-like fungus in the family Dothioraceae. It causes an aggressive canker disease of trembling aspen that results in widespread mortality of aspen across the boreal forest of Interior Alaska. Here we report a high-quality draft genome including functional annotation of this emerging fungal pathogen based on Oxford Nanopore Technologies long-read sequences. Our initial genome assembly totaled 23,960,169 bp and contained 18 contigs, and we identified 7,343 genes. This resource announcement provides new genomic data that are useful long term for improving our understanding of forest health in Alaska.

The extent of wildfires in tundra ecosystems has dramatically increased since the turn of the 21st century due to climate change and the resulting amplified Arctic warming. We simultaneously studied the recovery of vegetation, subsurface soil moisture, and active layer thickness (ALT) post-fire in the permafrost-underlain uplands of the Yukon-Kuskokwim Delta in southwestern Alaska to understand the interaction between these factors and their potential implications. We used a space-for-time substitution methodology with 2017 Landsat 8 imagery and synthetic aperture radar products, along with 2016 field data, to analyze tundra recovery trajectories in areas burned from 1953 to 2017. We found …

Bryce Canyon Aspen: Recent Trends, Future Actions, Paul C. Rogers
Aspen Bibliography
In cooperation with Bryce Canyon National Park, we undertook a survey of quaking aspen (Populus tremuloides Michx.) conditions throughout the Park with the intention of better understanding conditions and prescribing corrective measures where needed. There are clear disparities within the Park between sustainable aspen conditions and failing stands. Based on condition of mature trees, but most importantly regeneration and recruitment of juvenile stems, most aspen forests within Bryce Canyon are in poor condition. Aspen recruitment—generally sapling-sized trees that have survived browsing ungulates—is the most important metric of future stand resilience and here we found 83% of all aspen sample …

The former study suggests that Italian consumers are willing to pay premiums for new bio-based products but expect discounts on second-hand clothing, revealing a sustainability bias. This study adds more insights into such a bias by examining factors influencing consumers’ willingness to pay a premium for bio-based clothing and their expected discounts for second-hand items. Using Bayesian Mindsponge Framework (BMF) analytics on a dataset of 402 Italian consumers, the findings reveal that environmental concerns are positively associated with premiums for bio-based clothing, while higher income and education levels are also associated with the higher premium that consumers are willing to …

Edge Feathering Across Forest-Meadow Ecotones Increases Light Heterogeneity And Understory Plant Diversity, Aruni Kadawatha, Jean H. Burns
Faculty Scholarship
Ecotones, the transitional zones between distinct habitats, are vital for ecosystem functioning and habitat diversity. Traditional management practices frequently create abrupt boundaries, leading to stressful conditions for organisms. To address this challenge, an underutilized land management technique called “edge feathering”, which involves gradual thinning of the canopy along the forest edge, has been introduced. This study, con- ducted at Holden Arboretum in Kirtland, Ohio, investigated the effects of edge feathering on light availability and understory plant diversity in edge feathered and control treatments. We calculated the coefficient of variation in light availability as light heterogeneity and plant diversity indices at …

Wildfire is a natural disturbance in landscapes of the Western United States, but the effects and extents of fire are changing. Differences between historical and contemporary fire regimes can help identify reasons for observed changes in landscape composition. People living and working in the Great Basin, USA, are observing altered fire conditions, but spatial information about the degree and direction of change and departure from historical fire regimes is lacking. This study estimates how fire regimes have changed in the major Great Basin vegetation types over the past 60 years with comparisons to historical (pre-1900) fire regimes. We explore potential …

Monitoring And Modeling Legacy Tree Response To Restoration Treatments In The Klamath Mountains, Oregon, Usa, Isaac Joseph Ball
Dissertations and Theses
Climate change and its disruption of historical drought and wildfire patterns pose a substantial threat to forest health in the western United States. This threat is compounded by past management practices like fire suppression. The largest, oldest, and most ecologically valuable trees are particularly vulnerable, making their conservation a key objective of climate-adaptive forest management. Restoration treatments such as mechanical thinning have been shown to enhance tree growth and drought resilience in dry conifer forests, but long-term monitoring is necessary to understand their sustained effects. This study used dendroecological tree-ring analysis to investigate the effects of thinning on the growth, …

Occurrence Of Spotted Wing Drosophila (Drosophila Suzukii) In Wild Berries In Forested Areas Of Marquette And Keweenaw Counties, Upper Peninsula Of Michigan, Alexis M. Shatrau, Erika I. Hersch-Green
The Great Lakes Entomologist
Spotted-wing Drosophila (SWD, Drosophila suzukii Matsumura, Diptera: Drosophilidae) is an invasive fly that targets unripe soft-fruits causing premature ripening, dehiscence, and rotting. While the presence of SWD in agricultural systems is well-documented, much less is known about the host range of SWD in wild areas, especially in more northern latitudes where colder temperatures and short summers are thought to restrict their life-cycles and limit population growth. In 2019 and 2020, we collected wild berries from two counties in the Upper Peninsula of Michigan, with long, cold winters, to determine the prevalence, host range, and seasonal/temporal variation of SWD. We found …

Northern hardwood forests have long been assumed to be primarily nitrogen limited, but may often be co-limited by multiple elements. Nutrient limitation can be inferred through responses of foliar and litter chemistry to nutrient addition over time. We compared community-level foliar and litter chemistry and resorption efficiency in a long-term, factorial nitrogen (N) and phosphorus (P) fertilization study across 10 forest stands at three sites in New Hampshire, where N and P were added annually. We measured N, P, calcium (Ca), magnesium (Mg), and potassium (K) in foliage from codominant trees and in fresh litter in 2008–2010 (pretreatment) and again …

Understanding The Accuracy And Best Use Of The Woodland Stick As A Tree Height And Diameter Measurement Tool: A Case Study In Oregon, Francisca Belart, Lauren Grand, Alicia Christiansen
Journal of Extension
We conducted a study to assess the accuracy of the Woodland Stick in determining tree diameter and height as compared to professional measurements and how bias can affect tree volume calculation. After comparing professional measurements with five non-professionals (NP’s) using the Woodland Stick, we found that three out of five NP’s had significant differences in mean dbh, and all of the NP’s had significant differences in mean total height. The overall bias for dbh across users was +0.5 inches and +5.1 ft for height. These deviations can result in volume differences between 0 and 30 bf on a single tree.

In food product development and application, particle properties are crucial. Sieve analysis using a series of standardized sieves determined the particle size distribution, ranging from >500 µm to 53 µm. The particles exhibited stability, with an average size of 208.8 nm, a polydispersity index of 0.133, and a zeta potential of –20 mV. Bulk density (BD) and true density (TD) showed an inverse relationship with particle size, with BD ranging from 0.552 to 0.238 gcm–3 for particle sizes >500 to …
