On The Shoulders Of Giants: Continuing The Legacy Of Large-Scale Ecosystem Manipulation Experiments In Puerto Rico, Tana E. Wood, Grizelle González, Whendee L. Silver, Sasha C. Reed, Molly A. Cavaleri

School of Forest Resources and Environmental Science Publications

There is a long history of experimental research in the Luquillo Experimental Forest in Puerto Rico. These experiments have addressed questions about biotic thresholds, assessed why communities vary along natural gradients, and have explored forest responses to a range of both anthropogenic and non-anthropogenic disturbances. Combined, these studies cover many of the major disturbances that affect tropical forests around the world and span a wide range of topics, including the effects of forest thinning, ionizing radiation, hurricane disturbance, nitrogen deposition, drought, and global warming. These invaluable studies have greatly enhanced our understanding of tropical forest function under different disturbance regimes ...

Adaptation Strategies And Approaches For Forested Watersheds, P. Danielle Shannon, Christopher Swanston, Maria Janowiak, Stephen D. Handler, Kristen M. Schmitt, Leslie A. Brandt, Patricia Butler-Leopold

School of Forest Resources and Environmental Science Publications

Intentional climate adaptation planning for ecosystems has become a necessary part of the job for natural resource managers and natural resource professionals in this era of non-stationarity. One of the major challenges in adapting ecosystems to climate change is in the translation of broad adaptation concepts to specific, tangible actions. Addressing management goals and values while considering the long-term risks associated with local climate change can make forested watershed management plans more robust to uncertainty and changing conditions. We provide a menu of tiered adaptation strategies, which we developed with a focus on forests of the Midwest and Northeastern U ...


The Effects Of Matthew’S Storm Surge On Coastal Loblolly Pine And Wax Myrtle Understory Regeneration, Brynn D. Wilkinson 2019 South Carolina Governor's School for Science and Mathematics

The Effects Of Matthew’S Storm Surge On Coastal Loblolly Pine And Wax Myrtle Understory Regeneration, Brynn D. Wilkinson

Journal of the South Carolina Academy of Science

Hurricanes have detrimental effects on the environment and the economy. Not only are these effects felt immediately after the hurricane, but they last long after the winds have died down. They can affect future plant growth and mortality. In October of 2016 South Carolina was hit by Hurricane Matthew, a category 5 hurricane. Hobcaw Barony, our study site, was in the direct path of the storm. This created an opportunity to study the immediate effects on regeneration after a hurricane. Regenerations rates were measured along and around a surge line to determine regeneration and mortality rates. This data also allowed ...

Master’S Project: Vermont Town Forest Recreation Planning And Community Assistance Program: The Future Of Forest-Based Outdoor Recreation, Taylor M. Luneau

Rubenstein School Masters Project Publications

The Vermont Town Forest Recreation Planning Community Assistance Program (VTFRP) was a comprehensive community planning process held in ten diverse towns across Vermont. Led by the Urban and Community Forestry Program and the SE Group, the VTFRP helped towns develop a vision for the future management of their forests through open house workshops, site visits, steering committee meetings, and community surveys. The process provided towns with a forest recreation planning toolkit and an individualized action-based forest stewardship and recreation plan. By analyzing data from the community surveys and open house activities across all ten towns, my project considered the recreation ...


Experimental Evidence For Selection Against Hybrids Between Two Interfertile Red Oak Species, Oliver Gailing, Ruhua Zhang 2018 Michigan Technological University

Experimental Evidence For Selection Against Hybrids Between Two Interfertile Red Oak Species, Oliver Gailing, Ruhua Zhang

School of Forest Resources and Environmental Science Publications

Reproductive isolation between related oak species within one taxonomic section is incomplete. Even though pre- and post-zygotic isolation mechanisms have been described for interfertile oak species, natural hybridization is common in contact zones between related oaks. The apparent restriction of inter-specific hybrids between ecologically divergent species to intermediate environments in contact zones suggests postzygotic isolation via environmental selection against hybrids in parental environments. Overrepresentation of hybrids in seeds as compared to adult trees provides additional indirect evidence for selection against hybrids. Here, we used genetic assignment analyses in progeny obtained from a sympatric stand of Quercus rubra and Quercus ellipsoidalis ...


Within-Canopy Experimental Leaf Warming Induces Photosynthetic Decline Instead Of Acclimation In Two Northern Hardwood Species, Kelsey R. Carter, Molly A. Cavaleri 2018 Michigan Technological University

Within-Canopy Experimental Leaf Warming Induces Photosynthetic Decline Instead Of Acclimation In Two Northern Hardwood Species, Kelsey R. Carter, Molly A. Cavaleri

School of Forest Resources and Environmental Science Publications

Northern hardwood forests are experiencing higher temperatures and more extreme heat waves, potentially altering plant physiological processes. We implemented in-situ leaf-level warming along a vertical gradient within a mature forest canopy to investigate photosynthetic acclimation potential of two northern hardwood species, Acer saccharum and Tilia americana. After 7 days of +3°C warming, photosynthetic acclimation was assessed by measuring differences between heated and control photosynthetic rates (Aopt) at leaf optimum temperatures (Topt). We also measured the effects of warming and height on maximum rates of Rubisco carboxylation, stomatal conductance, transpiration, and leaf traits: leaf area, leaf mass per ...


Gene Network Analysis Of Poplar Root Transcriptome In Response To Drought Stress Identifies A Ptajaz3ptarap2.6-Centered Hierarchical Network, Madhumita Dash, Yordan S. Yordanov, Tatyana Georgieva, Hairong Wei, Victor Busov 2018 Michigan Technological University

Gene Network Analysis Of Poplar Root Transcriptome In Response To Drought Stress Identifies A Ptajaz3ptarap2.6-Centered Hierarchical Network, Madhumita Dash, Yordan S. Yordanov, Tatyana Georgieva, Hairong Wei, Victor Busov

School of Forest Resources and Environmental Science Publications

Using time-series transcriptomic data from poplar roots undergoing polyethylene glycol (PEG)-induced drought stress, we built a genetic network model of the involved putative molecular responses. We found that the network resembled a hierarchical structure. The highest hierarchical level in this structure is occupied by 9 genes, which we called superhubs because they were primarily connected to 18 hub genes, which are then connected to 2,934 terminal genes. We were only able to regenerate transgenic plants overexpressing two of the superhubs, suggesting that the majority of the superhubs might interfere with the regeneration process and did not allow recovery ...


Understory Community Assembly Following Wildfire In Boreal Forests: Shift From Stochasticity To Competitive Exclusion And Environmental Filtering, Bo Liu, Han Y. H. Chen, Jian Yang 2018 Chinese Academy of Sciences, China

Understory Community Assembly Following Wildfire In Boreal Forests: Shift From Stochasticity To Competitive Exclusion And Environmental Filtering, Bo Liu, Han Y. H. Chen, Jian Yang

Forestry and Natural Resources Faculty Publications

Understory vegetation accounts for the majority of plant species diversity and serves as a driver of overstory succession and nutrient cycling in boreal forest ecosystems. However, investigations of the underlying assembly processes of understory vegetation associated with stand development following a wildfire disturbance are rare, particularly in Eurasian boreal forests. In this study, we measured the phylogenetic and functional diversity and trait dispersions of understory communities and tested how these patterns changed with stand age in the Great Xing'an Mountains of Northeastern China. Contrary to our expectation, we found that understory functional traits were phylogenetically convergent. We found that ...

Interactions Between Fire Severity And Forest Biota In The Central Sierra Nevada: Formation And Impact Of Small-Scale Fire Refugia And The Effect Of Fire On Forest Structure Predictive Of Fisher (Pekania Pennanti) Den Habitat, Erika M. Blomdahl 2018 Utah State University

Interactions Between Fire Severity And Forest Biota In The Central Sierra Nevada: Formation And Impact Of Small-Scale Fire Refugia And The Effect Of Fire On Forest Structure Predictive Of Fisher (Pekania Pennanti) Den Habitat, Erika M. Blomdahl

All Graduate Theses and Dissertations

Fire is a natural and essential component of forests in western North America. Fire maintains biodiversity through the creation of different habitat types, and regular fire rotations reduce the accumulation of woody fuels and thick understory plant densities that give rise to catastrophic fire. The practice of fire exclusion has altered western forests and increased the risk of widespread change under rising temperatures projected for the 21st century. To manage for the reintroduction of fire it is critical that we understand the interactions between fire and forest biota in recently fire-suppressed forests.

In Chapter 2, I studied the formation ...

Importance Of Forests Outside Protected Area Networks For Large-Seeded Tree Species And Their Large-Bodied Avian Frugivores--A Study In Vazhachal Reserve Forest, India, Aditi Achyut Lele

Theses and Dissertations

Western Ghats, the mountain chain running along the west coast of India, is one of eight global hotspots of biodiversity and is particularly notable for its endemic flora and fauna. Yet only 10% of this land enjoys the protected status. Vast forested lands exist outside the protected network of national parks and wildlife sanctuaries in the form of reserve forests, community forests, and private lands. The present study sought to understand the role of such forests in the context of ecological system involving large-seeded tree species that depend on large-bodied avian frugivores for seed dispersal. I conducted a study over ...


Spatio-Temporal Reconstruction Of Remote Sensing Observations, Kamrul Khan 2018 University of Arkansas, Fayetteville

Spatio-Temporal Reconstruction Of Remote Sensing Observations, Kamrul Khan

Theses and Dissertations

The USDA Forest Service aims to use satellite imagery for monitoring and predicting changes in forest conditions over time within the country. We specifically focus on a 230, 400 hectares region in north-central Wisconsin between 2003 - 2012. The auxiliary data collected from the satellite imagery of this region are relatively dense in space and time and can be used to efficiently predict how the forest condition changed over that decade. However, these records have a significant proportion of missing values due to weather conditions and system failures. To fill in these missing values, we build spaciotemporal models based on fixed ...


Bryophyte Assemblages On American Hornbeam (Carpinus Caroliniana) And The Surrounding Arboreal Communities Within The Forest Of East Texas, Cassey Edwards 2018 Stephen F. Austin State University

Bryophyte Assemblages On American Hornbeam (Carpinus Caroliniana) And The Surrounding Arboreal Communities Within The Forest Of East Texas, Cassey Edwards

Electronic Theses and Dissertations

The bryophytes, the non-vascular plants, include the mosses (Bryophyta with approximately 13,000 species), the liverworts (Marchantiophyta with approximately 5,000 species), and the hornworts (Anthocerotophyta with approximately 150 species). Initial observations indicated that the midstory tree Carpinus caroliniana Walter (American hornbeam) has a bryophyte composition with an unusually high diversity of leafy liverworts. Voucher samples were taken from the four intercardinal directions (Northeast, Northwest, Southwest, and Southeast) from six Carpinus trees and their nearest neighbor that was neither Pinus nor another Carpinus at each of six sites across East Texas. Percent coverage, species richness, Shannon’s diversity and Pielou ...


Soy- Based Flexographic Ink For Linerboard Printing, Rahul Ramchandra Pingale 2018 Western Michigan University

Soy- Based Flexographic Ink For Linerboard Printing, Rahul Ramchandra Pingale

Master's Theses

Many printing inks use volatile solvents in the formulation, which are hazardous to the environment from emission of VOC’s and at the same time, synthetic resins in these inks are not biodegradable. These problems with the fluctuating and rising price of petroleum are main reasons to look for new resources for making more environmentally friendly printing inks. The majority of the commercially available water based inks are formulated based on using acrylic resins, synthetic colorants, solvents/water and additives, which are the common main components for formulating printing inks. In this research, soy proteins were tested for their suitability ...


Modeling The Response Of Black Walnut -Dominant Mixed Hardwoods To Seasonal Climate Effects With Uav-Based Hyperspectral Sensor And Aerial Photogrammetry, Tyler G. Bradford 2018 Missouri State University

Modeling The Response Of Black Walnut -Dominant Mixed Hardwoods To Seasonal Climate Effects With Uav-Based Hyperspectral Sensor And Aerial Photogrammetry, Tyler G. Bradford

MSU Graduate Theses

The development of compact sensors in recent years has inspired the use of UAS-based hyperspectral and aerial imaging techniques for small-scale remote sensing applications. With increasing concerns about climate change, spectrally-derived vegetation indices (VIs) have proven useful for quantifying stress-induced vegetation response. The goal of this study was to develop predictive models and assess methodology for modeling the biological response of a black walnut -dominant mixed hardwood stand to seasonal climate events using UAV-based hyperspectral remote-sensing. The derived VIs were evaluated against the means of four seasonal measures of climate calculated for a two-week period prior to the flight date ...

Bilge Nazli Altay

In recent years, traditional printing methods have been integrated to print flexible electronic devices and circuits. Since process requirements for electronics diff er from those for graphic printing, the fundamentals require rediscovery mainly to optimize manufacturing techniques and to find cost reduction methods without compromising functional performance. In addition, alternative inks need to be formulated to increase the variety of functional inks and to pioneer new product developments. In this report, we investigate a thermoplastic-based nickel ink prototype to print electrodes using a screen-printing process. Process fundamentals are explored, and cost reduction methods are addressed by studying ...
