Forest Development Over A Twenty-Year Chronosequence Of Reforested Urban Sites, Kenton L. Sena, Zachary J. Hackworth, John M. Lhotka May 2021

Forest Development Over A Twenty-Year Chronosequence Of Reforested Urban Sites, Kenton L. Sena, Zachary J. Hackworth, John M. Lhotka

Lewis Honors College Faculty Publications

Urbanization causes a variety of negative ecological impacts, impairing forests, streams, and other ecosystems. While urban forests are the subject of increasing research attention, planted urban forests are less well-understood than remnant forests; however, these systems may be distinct in terms of ecosystem structure and function. The current study investigates a chronosequence of reforested urban sites in Lexington, KY, USA, with a focus on overstory and understory woody plant community characteristics. Monitoring plots were established in each of the 20 sites; tree height, dbh, and species were surveyed for the overstory, and species and height were surveyed for the understory ...


Three Centuries Of Vegetation Change In The William & Mary College Woods Reconstructed Using Phytoliths, Timothy Terlizzi May 2021

Three Centuries Of Vegetation Change In The William & Mary College Woods Reconstructed Using Phytoliths, Timothy Terlizzi

Undergraduate Honors Theses

The College Woods, west of William & Mary’s campus, consists of ~900 acres of protected southern mixed hardwood forest. The woods surround Lake Matoaka, a former millpond established in ~1700. Despite the rich history of the area, little is known about how the dominant vegetative landcover has shifted over the last 300 years. This study set out to quantify the modern vegetation within the College Woods via the phytolith assemblages within the soil and identify shifts in the assemblages since the creation of Lake Matoaka and whether these changes are distinct from the vegetation that existed in the area before the lake. To accomplish this, I studied the composition and preservation of phytoliths – silica bodies generated within and between plant cells. The study focused on the two questions: do the modern phytolith assemblages in the soil of the College Woods reflect the vegetation present and can phytoliths within the sediments of Lake Matoaka be used to identify the dominant vegetative communities over the last ~300 years? I addressed these questions with three approaches: 1) Identify the primary phytolith producing taxa within the College Woods; 2) Identify the modern phytolith assemblages within the soil of the College Woods; 3) Identify the differences between phytolith assemblages from the lake sediment core samples. I found the following: 1) The production of phytoliths varies heavily between and within different common taxa of the College Woods, with species of oaks (Quercus spp.) unpredictably producing phytoliths and beeches (Fagus grandifolia) likely contributing the majority of dicot phytoliths; 2) The modern phytolith assemblages of the College Woods reflect a low phytolith producing environment, and the vegetative homogeneity is reflected in the phytolith record; 3) The ...

The subject property is currently owned by the Delta Wind Birds organization. In our scenario, this documentation report will serve to aid in the conversion of our subject property into a conservation easement in ...


A Study Of Old Field Succession At The Center For Environmental Education And Research (Ceer), Noah Vincent Apr 2021

A Study Of Old Field Succession At The Center For Environmental Education And Research (Ceer), Noah Vincent

Senior Scholars Day

Using the successional plots located at the Center for Environmental Education and Research (CEER), the species composition and distribution of woody plant species were determined for four of these plots. Old field succession has large implications conservation considering how much land is used by humans for agricultural practice. Invasive species are also a growing threat to conservation, particularly in early successional environments, such as old fields, that allow them to have a foothold to grow. How these invasives impact native populations and the trajectory of succession is critical to conserving biodiversity of native organisms. Understanding how species abundance and distribution ...

Development Of Mine Soils In A Chronosequence Of Forestry-Reclaimed Sites In Eastern Kentucky, Kenton L. Sena, Kevin M. Yeager, Christopher D. Barton, John M. Lhotka, William E. Bond, Kimberly J. Schindler

Lewis Honors College Faculty Publications

Surface mining for coal has contributed to widespread deforestation and soil loss in coal mining regions around the world, and particularly in Appalachia, USA. Mined land reforestation is of interest in this and other regions where forests are the dominant pre-mining land use. This study evaluated mine soil development on surface-mined sites reforested according to the Forestry Reclamation Approach, representing a chronosequence of time ranging from 0 to 19 years after reclamation. Soils were sampled in depth increments to 50 cm and analyzed for a suite of soil physical and chemical characteristics. Overall, soil fines (silt + clay) tended to increase ...

B10: Controlling Saltwater Intrusion: Aiding The Recovery Of Freshwater Ecosystems, Willem Maniago, Stefanie Whitmire, Dan Hitchcock Apr 2021

B10: Controlling Saltwater Intrusion: Aiding The Recovery Of Freshwater Ecosystems, Willem Maniago, Stefanie Whitmire, Dan Hitchcock

Annual Research Symposium

As sea levels rise, it is imperative to understand the effects of saltwater intrusion on freshwater ecosystems. This is especially true in the coastal wetlands of the SE US, where freshwater forests are dying from exposure to salinity. One management strategy that could prevent salinity intrusion in surface waters are water control structures (WCS). The Great Reserve, located outside of Georgetown, SC, represents a biodiverse freshwater forested wetland affected by saltwater intrusion from the adjacent tidal Black River. Several years ago, scientists and landowners observed the degradation of the ecosystem. The owners of the property installed a WCS at the ...


Seed Rain–Successional Feedbacks In Wet Tropical Forests, Nohemi Huanca Nuñez, Robin L. Chazdon, Sabrina E. Russo Apr 2021

Seed Rain–Successional Feedbacks In Wet Tropical Forests, Nohemi Huanca Nuñez, Robin L. Chazdon, Sabrina E. Russo

Faculty Publications in the Biological Sciences

Abstract

Tropical forest regeneration after abandonment of former agricultural land depends critically on the input of tree seeds, yet seed dispersal is increasingly disrupted in contemporary human-modified landscapes. Here, we introduce the concept of seed rain–successional feedbacks as a deterministic process in which seed rain is shaped by successional dynamics internal to a forest site and that acts to reinforce priority effects. We used a combination of time series and chronosequence approaches to investigate how the quantity and taxonomic and functional composition of seed rain change during succession and to evaluate the strength of seed rain–successional feedbacks, relative ...

Mining 30 Years Of Conifer Records At The Baker Arboretum, Monika Decker

Masters Theses & Specialist Projects

Only limited data had been published on the survivability of specimens within public gardens. This may be due to not enough data collected or how vast the plant selections are in the gardens. The Baker Arboretum has collected data by accessioning plant collections over a period of 30 years. The Baker Arboretum has its specimens GIS mapped on the 115-acre property for easy location and detection of the the woody ornamental plants. However, little research is available to understand which coniferous specimens have the best success in the garden. In this study, six separate binomial logistic regressions were run to ...

Temperate coniferous forests sustain the highest levels of biomass of all terrestrial ecosystems and belong to the major carbon sinks on Earth. However, the community composition and its functional diversity depending on the habitat have yet to be unveiled. Here, we analyzed the proteomes from litter, plant roots, rhizosphere, and bulk soil in a temperate coniferous forest at two time points to improve the understanding of the interplay between bacterial and eukaryotic communities in different habitats. Our metaproteomic approach yielded a total of 139,127 proteins that allowed to differentiate the contribution of microbial taxa to protein expression as well ...

Finding Purpose In The Conservation Of Biodiversity By The Commingling Of Science And Ethics, John A. Vucetich, Ewan A. Macdonald, Dawn Burnham, Jeremy T. Bruskotter, Dominic D.P. Johnson, David W. Macdonald Mar 2021

Finding Purpose In The Conservation Of Biodiversity By The Commingling Of Science And Ethics, John A. Vucetich, Ewan A. Macdonald, Dawn Burnham, Jeremy T. Bruskotter, Dominic D.P. Johnson, David W. Macdonald

Michigan Tech Publications

Averting the biodiversity crisis requires closing a gap between how humans tend to behave, individually and collectively, and how we ought to behave—“ought to” in the sense of behaviors required to avert the biodiversity crisis. Closing that gap requires synthesizing insight from ethics with insights from social and behavioral sciences. This article contributes to that synthesis, which presents in several provocative hypotheses: (i) Lessening the biodiversity crisis requires promoting pro-conservation behavior among humans. Doing so requires better scientific understanding of how one’s sense of purpose in life affects conservation-relevant behaviors. Psychology and virtue-focused ethics indicate that behavior is ...

Forests are being converted to agriculture throughout the Afrotropics, driving declines in sensitive rainforest taxa such as understorey birds. The ongoing expansion of cocoa agriculture, a common small-scale farming commodity, has contributed to the loss of 80% rainforest cover in some African countries. African cocoa farms may provide habitat for biodiversity, yet little is known about their suitability for vertebrate fauna, or the effect of farm management on animal communities. Here, we report the first in-depth investigation into avian diversity and community composition in African cocoa, by assembling a dataset of 9,566 individual birds caught across 83 sites over ...

S4e2: What’S Your Relationship With The Forest?, Ron Lisnet, Jessica Leahy

The Maine Question

Maine is the most forested state in the country, and its residents interact with forests regularly in many different ways. They provide supplies for various products, which fuels industry and job creation, and space for outdoor recreation. These interactions, which help define Maine’s identity, are the subject of Jessica Leahy’s research. As a professor in UMaine’s School of Forest Resources, she studies the human dimensions of forestry and other natural resources. In this episode of “The Maine Question,” Leahy discusses her work, the ways forests impact our lives and how our actions affect them.

Although renewable energy holds great promise in mitigating climate change, there are socioeconomic and ecological tradeoffs related to each form of renewable energy. Forest‐related bioenergy is especially controversial, because tree plantations often replace land that could be used to grow food crops and can have negative impacts on biodiversity. In this study, we examined public perceptions and ecosystem service tradeoffs between the provisioning services associated with cover types associated with bioenergy crop (feedstock) production and forest habitat‐related supporting services for birds, which themselves provide cultural and regulating services. We combined a social survey‐based assessment of local values ...


Early Wildfire Detection With Line Sensors, Virginia Yan Mar 2021

Early Wildfire Detection With Line Sensors, Virginia Yan

Master's Theses

Over the last few years, wildfires have become more devastating to communities as the fires are inevitably destructive to many homes, businesses, and ecosystems. Frequent wildfires also pose a significant threat to power grids and nearby residents as they can damage transmission lines and other electrical equipment, which in turn can cause major power shutdowns. Especially in western U.S., severe drought conditions and weather variability cause residents to become more vulnerable to wildfire disasters as their safety is threatened. We are incompetent to control the wildfires effectively despite existing advanced technologies. Hence, an algorithm based on energy conservation and ...

Early Bud-Break 1 And Early Bud-Break 3 Control Resumption Of Poplar Growth After Winter Dormancy, Abdul Azeez, Yiru Chen Zhao, Rajesh Kumar Singh, Yordan S. Yordanov, Madhumita Dash, Pal Miskolczi, Katja Stojkovic, Steven H. Strauss, Rishikesh P. Bhalerao, Victor Busov

Michigan Tech Publications

Bud-break is an economically and environmentally important process in trees and shrubs from boreal and temperate latitudes, but its molecular mechanisms are poorly understood. Here, we show that two previously reported transcription factors, EARLY BUD BREAK 1 (EBB1) and SHORT VEGETATIVE PHASE-Like (SVL) directly interact to control bud-break. EBB1 is a positive regulator of bud-break, whereas SVL is a negative regulator of bud-break. EBB1 directly and negatively regulates SVL expression. We further report the identification and characterization of the EBB3 gene. EBB3 is a temperature-responsive, epigenetically-regulated, positive regulator of bud-break that provides a direct link to activation of the cell ...

Griffith, Virginia H. Dale, Chelsea Schelly, Anna Maria Marshall, Valoree Gagnon, Weston M. Eaton, Kristin Floress

Michigan Tech Publications

Community and stakeholder engagement is increasingly recognized as essential to science at the nexus of food, energy, and water systems (FEWS) to address complex issues surrounding food and energy production and water provision for society. Yet no comprehensive framework exists for supporting best practices in community and stakeholder engagement for FEWS. A review and meta‐synthesis were undertaken of a broad range of existing models, frameworks, and toolkits for community and stakeholder engagement. A framework is proposed that comprises situational awareness of the FEWS place or problem, creation of a suitable culture for engagement, focus on power‐sharing in the ...


Consequences Of Increased Variation In Peatland Hydrology For Carbon Storage: Legacy Effects Of Drought And Flood In A Boreal Fen Ecosystem, Evan Kane, Catherine M. Dieleman, Danielle L. Rupp, Kevin H. Wyatt Feb 2021

Consequences Of Increased Variation In Peatland Hydrology For Carbon Storage: Legacy Effects Of Drought And Flood In A Boreal Fen Ecosystem, Evan Kane, Catherine M. Dieleman, Danielle L. Rupp, Kevin H. Wyatt

Michigan Tech Publications

Globally important carbon (C) stores in boreal peatlands are vulnerable to altered hydrology through changes in precipitation and runoff patterns, groundwater inputs, and a changing cryosphere. These changes can affect the extent of boreal wetlands and their ability to sequester and transform C and other nutrients. Variation in precipitation patterns has also been increasing, with greater occurrences of both flooding and drought periods. Recent work has pointed to the increasing role of algal production in regulating C cycling during flooded periods in fen peatlands, but exactly how this affects the C sink-strength of these ecosystems is poorly understood. We evaluated ...


Environmental Soft Law As A Governance Strategy, Cary Coglianese Jan 2021

Environmental Soft Law As A Governance Strategy, Cary Coglianese

Faculty Scholarship at Penn Law

Soft law governance relies on nongovernmental institutions that establish and implement voluntary standards. Compared with traditional hard law solutions to societal and economic problems, soft law alternatives promise to be more politically feasible to establish and then easier to adapt in the face of changing circumstances. They may also seem more likely to be flexible in what they demand of targeted businesses and other entities. But can soft law actually work to solve major problems? This Article considers the value of soft law governance through the lens of three major voluntary, nongovernmental initiatives that address environmental concerns: (1) ISO 14001 ...
