Reconstruction Of Piñon–Juniper Woodlands In The Sky Islands Of The Davis Mountains, Texas, Usa, Mohammad Bataineh, Brian P. Oswald, Hans M. Williams, Dan Unger, I-Kuai Hung

Faculty Publications

Piñon (Pinus spp. L.)–juniper (Juniperus spp. L.) woodlands’ historical stand structures were recreated to provide reference conditions and document long‐term changes in the Sky Islands of the Davis Mountains, Texas. Restoration of these isolated woodlands requires insights into the range of variability in current and historical stand structures, as well as an understanding of the spatiotemporal establishment and recruitment patterns of tree species. With drastic changes in forests and woodlands of the Southwestern United States widely reported, the main objective of this study was to reconstruct woodland tree temporal and spatial establishment patterns. A stratified random sampling approach was used …

Impacts Of Forest Management And Timber Harvest Practices On Karst Critical Zone Processes In Tongass National Forest, Alaska, Anna Gwendolyn Harris

Masters Theses & Specialist Projects

This study characterizes the throughfall, hydrogeochemistry, dissolution rates, and carbon sources of two proximate temperate rainforest cave systems within the Tongass National Forest in Southeast Alaska (Tongass). Study sites include: an old-growth forest, characterized by having never been logged (containing Walkabout Cave system); and a previously logged – within thirty years, second-growth forest (containing Zina Cave system). Precipitation data were recorded over a five-month period at 10-minute intervals, to understand the effects of throughfall between the altering old and second-growth canopies. At each major spring for the two cave systems, high-resolution data were collected from June 29 through November 21, …

Hot But Not Dry: Modest Changes In Water Relations For An Epiphytic Bromeliad In A Tropical Dry Deciduous Forest, Saúl Hernández-Robinson, Eric A. Graham, Olivia Hernández-González, Roberth Us-Santamaría, José Luis Simá, Fernando Arellano-Martín, José Luis Andrade

All Faculty Scholarship for the College of the Sciences

Premise of research. Epiphytic bromeliads endure intense seasonal environmental changes in the canopy of dry tropical deciduous forests. The analysis of the physiological responses of these epiphytes to environmental changes can be useful in assessing their plasticity, vulnerability, and adaptations to such extreme habitats.

Methodology. We measured microenvironmental variables and water relations for plants of the epiphytic bromeliad Tillandsia brachycaulos in three microhabitats within the canopy of a dry tropical forest. We measured individual plants for seasonal and spatial differences in light, leaf temperature, osmotic potential, cell wall elasticity, and relative capacitance as indications of their physiological responses …

The overall goal of the GLP is to maintain a database of the current state of the university’s trees. This survey includes the collection of the field data of the trees (common name, Latin name, native status, Global Positioning System (GPS) location, diameter at breast height (DBH), height, ground cover, die back, and condition). These data are also analyzed using CITYgreen by American Forests as well as the i-Tree ECO model of the United States Department of Agriculture …

Climate, Snowmelt Dynamics And Atmospheric Deposition Interact To Control Dissolved Organic Carbon Export From A Northern Forest Stream Over 26 Years, Karl M. Meingast, Evan Kane, Ashley A. Coble, Amy Marcarelli, David Toczydlowski

Michigan Tech Publications, Part 1

Increasing concentrations of dissolved organic carbon (DOC) have been identified in many freshwater systems over the last three decades. Studies have generally nominated atmospheric deposition as the key driver of this trend, with changes in climatic factors also contributing. However, there is still much uncertainty concerning net effects of these drivers on DOC concentrations and export dynamics. Changes in climate and climate mediated snowfall dynamics in northern latitudes have not been widely considered as causal factors of changes in long-term DOC trends, despite their disproportionate role in annual DOC export. We leveraged long-term datasets (1988–2013) from a first-order forested tributary …

Enrollment Decision-Making By Students In Forestry And Related Natural Resource Degree Programmes Globally, T. L. Bal, M. D. Rouleau, T. L. Sharik, A. M. Wellstead

Michigan Tech Publications, Part 1

A survey of 396 undergraduate and graduate students from 51 countries on 5 continents currently enrolled in Forestry or Related Natural Resource (FRNR) degree programmes was conducted of attendees to the International Union of Forest Research Organizations' (IUFRO) conference in Salt Lake City, Utah, 2014. These perspectives come from some of the most active students in their respective fields. We explored the motivating reasons for enrolling in their current FRNR programme, and conversely why they may have been hesitant to do so. Results indicate that enjoyment of nature was the most important factor on average driving the decision to enroll, …

Public Preferences And Willingness To Pay For Invasive Forest Pest Prevention Programs In Urban Areas, Damian C. Adams, Jose R. Soto, John Lai, Francisco J. Escobedo, Sergio Alvarez, Abu S.M.G. Kibria

Faculty Scholarship and Creative Works

Invasive forest pests can cause environmental and economic damage amounting to billions of dollars (US) in lost revenues, restoration and response costs, and the loss of ecosystem services nationwide. Unfortunately, these forest pests do not stay confined to wildland forest areas and can spread into suburban and urban areas, imposing significant costs on local governments, homeowners, and management agencies. In this study, a contingent valuation experiment is used to estimate Florida residents’ willingness to pay (WTP) a monthly utility fee that would protect urban forests from invasive pests by implementing a monitoring and prevention program for their early detection and …

Quantitative Analysis Of Phytochemical Compounds In Barks And Leaves Of Okoubaka Aubrevillei Collected From Iwo, Southwestern Nigeria, Oluwatoyin Opeyemi Akintola, Adeboyin Funmi Aderounmu, Isaac Oluwaseyi Abiola, Kolawole Emmanuel Abodurin, Tunde Adeniran, Festus Agboola, Oluwayemisi Samuel Olokeogun

Journal of Bioresource Management

Okoubaka aubrevillei is an indigenous and sacred tropical tree in Africa. It is rare with allelopathic properties and has relatively little information available in terms of what is responsible for its usage for medicinal and traditional usage. The phytochemical screening and quantitative analysis of the compounds in the barks and leaves of Okoubaka aubrevillei was determined to ascertain and establish its earlier claimed usage as traditional and modern medicine. The most important classes of secondary metabolites (phytochemical compounds) specifically alkaloids, flavonoids, tannins, saponins, anthraquinnes, mucilages, oses, holosides, coumarin and glycosides were detected in both, the leaves and barks of the …

Photosynthetic And Respiratory Acclimation Of Understory Shrubs In Response To In Situ Experimental Warming Of A Wet Tropical Forest, Kelsey R. Carter, Tana E. Wood, Sasha C. Reed, Elsa Schwartz, Madeline B. Reinsel, Xi Yang, Molly A. Cavaleri

Michigan Tech Publications, Part 1

Despite the importance of tropical forests to global carbon balance, our understanding of how tropical plant physiology will respond to climate warming is limited. In addition, the contribution of tropical forest understories to global carbon cycling is predicted to increase with rising temperatures, however, in situ warming studies of tropical forest plants to date focus only on upper canopies. We present results of an in situ field-scale +4°C understory infrared warming experiment in Puerto Rico (Tropical Responses to Altered Climate Experiment; TRACE). We investigated gas exchange responses of two common understory shrubs, Psychotria brachiata and Piper glabrescens, after exposure …

Vegetative And Edaphic Responses In A Northern Mixed Conifer Forest Three Decades After Harvest And Fire: Implications For Managing Regeneration And Carbon And Nitrogen Pools, R. Kasten Dumroese, Martin Jurgensen, Deborah S. Page-Dumroese

Michigan Tech Publications, Part 1

Research Highlights: This experiment compares a range of combinations of harvest, prescribed fire, and wildfire. Leveraging a 30-year-old forest management-driven experiment, we explored the recovery of woody species composition, regeneration of the charismatic forest tree species Larix occidentalis Nutt., and vegetation and soil carbon (C) and nitrogen (N) pools. Background and Objectives: Initiated in 1967, this experiment intended to explore combinations of habitat type phases and prescribed fire severity toward supporting regeneration of L. occidentalis. At onset of the experiment, a wildfire affected a portion of the 60 research plots, allowing for additional study. Our objective was to better understand …

Roosting Ecology Of A Declining Population Of Northern Long-Eared Bats (Myotis Septentrionalis) In The Ozark-St. Francis National Forest Of Arkansas, Kyle Norris Edmonds

Student Theses and Dissertations

Ecological and monetary values associated with bat species are immense. Unfortunately, these benefits are at risk as disease and habitat loss have resulted in significant declines of bat populations throughout the eastern United States. Wildlife biologists and managers work tirelessly to combat the effects of these threats. Collections of species-level data during surveys provide managers with invaluable information that can be used in identification of emerging population trends. This material can then be used to generate new habitat management plans or revise existing plans in order to address the objectives of primary management goals. This thesis outlines anthropogenic factors, interspecific …

Ecological Factors Influencing Wild Pig Damage To Planted Pine And Hardwood Seedlings, Micah P. Fern, James B. Armstrong, Rebecca J. Barlow, John S. Kush

Human–Wildlife Interactions

Expanding wild pig (Sus scrofa) populations across the southern United States has the potential to impact longleaf pine (Pinus palustris) restoration efforts. The depredation of planted pine seedlings is the most widespread and economically costly damage caused by wild pigs in forest plantations. A better understanding of the ecological factors affecting depredation rates will allow managers to implement best management practices to reduce seedling mortality from wild pigs at their most vulnerable stage of growth. From March 2016 to March 2017, we evaluated wild pig preferences for planted pine and hardwood species at a 34.4-ha cutover …
