Michigan Tech Publications, Part 2

Boreal peatlands store vast amounts of soil organic carbon (C) owing to the imbalance between productivity and decay rates. In the recent decades, this carbon stock has been exposed to a warming climate. During the past decade alone, the Arctic has warmed by ∼ 0.75°C which is almost twice the rate of the global average. Although, a wide range of studies have assessed peatlands’ C cycling, our understanding of the factors governing source / sink dynamics of peatland C stock under a warming climate remains a critical uncertainty at site, regional, and global scales. Here our focus was on answering …

Prediction Of Turfgrass Quality Using Multispectral Uav Imagery And Ordinal Forests: Validation Using A Fuzzy Approach, Alexander Hernandez, Shaun Bushman, Paul Johnson, Matthew D. Robbins, Kaden Patten

Plants, Soils, and Climate Faculty Publications

Protocols to evaluate turfgrass quality rely on visual ratings that, depending on the rater’s expertise, can be subjective and susceptible to positive and negative drifts. We developed seasonal (spring, summer and fall) as well as inter-seasonal machine learning predictive models of turfgrass quality using multispectral and thermal imagery collected using unmanned aerial vehicles for two years as a proof-of-concept. We chose ordinal regression to develop the models instead of conventional classification to account for the ranked nature of the turfgrass quality assessments. We implemented a fuzzy correction of the resulting confusion matrices to ameliorate the probable drift of the field-based …

Understanding tree transpiration variability is vital for assessing ecosystem water-use efficiency and forest health amid climate change, yet most landscape-level measurements do not differentiate individual trees. Using canopy temperature data from thermal cameras, we estimated the transpiration rates of individual trees at Harvard Forest and Niwot Ridge. PT-JPL model was used to derive latent heat flux from thermal images at the canopy-level, showing strong agreement with tower measurements (R2 = 0.70–0.96 at Niwot, 0.59–0.78 at Harvard at half-hourly to monthly scales) and daily RMSE of 33.5 W/m2 (Niwot) and 52.8 W/m2 (Harvard). Tree-level analysis revealed species-specific responses to …

Turkish Journal of Agriculture and Forestry

Drought is one of the important factors that cause a decrease in productivity and quality in plant cultivation. Stress tolerance in plants can be increased or damage can be reduced by various exogenous applications. One of them is flavonoids, which have an important role in the response to stress through changes that occur at the endogenous level in the plant due to drought stress. The effects of exogenous treatment of chrysin, a member of the flavonoid group, on tomato seedlings grown under water deficit were examined. Different doses (C0: Control with no treatment, C1: 0.1 mM, C2: 0.5 mM and …

PANDION: The Osprey Journal of Research and Ideas

Artist Statement

Latticed Stinkhorn is a watercolor piece originally created for the special gallery of the 2023 Scientific Illustration course at the University of North Florida. It was inspired by my enduring fascination with the world of fungi, particularly specimens of the family Phallaceae. This watercolor piece offers a simple perspective of Clathrus ruber, a species commonly referred to as Latticed Stinkhorn. Like many members of the family, the reproductive fruiting body first surfaces encased in a cream-colored soft shell with a texture comparable to a leathery reptile egg. As the body ages, the initial shell disintegrates to reveal a …


Coyotes Can Do ‘Puppy Dog Eyes’ Too: Comparing Interspecific Variation In Canis Facial Expression Muscles, Patrick Cunningham, Mahita Shankar, Bridgett Vonholdt, Kristin Brzeski, Sarah S. Kienle Oct 2024

Coyotes Can Do ‘Puppy Dog Eyes’ Too: Comparing Interspecific Variation In Canis Facial Expression Muscles, Patrick Cunningham, Mahita Shankar, Bridgett Vonholdt, Kristin Brzeski, Sarah S. Kienle

Michigan Tech Publications, Part 2

Facial expressions are critical for non-verbal communication. The Canis genus epitomizes the interplay between behaviour and morphology in the evolution of non-verbal communication. Recent work suggests that the levator anguli oculi medialis (LAOM) muscle is unique to dogs (Canis familiaris) within the Canis genus and evolved due to domestication. The LAOM raises the inner eyebrows, resulting in the ‘puppy dog eyes’ expression. Here, we test whether the LAOM is a derived trait in dogs by (i) examining the facial expression muscles of a closely related and ancestral wild Canis species, the coyote (C. latrans) and (ii) comparing our results with …

Perceptions Of Spruce Budworm Monitoring, Management, And Remote Sensing Technology In Maine's Forest Sector, Allison E. Foster, Adam Daigneualt, Parinaz Rahimzadeh-Bajgiran, Aaron Weiskittel

Maine Policy Review

Eastern spruce budworm (Choristoneura fumiferana Clem; SBW) is a native forest pest that can severely damage spruce-fir forests in Maine. Monitoring SBW defoliation and populations is important to ensure forest managers make timely decisions regarding forest management. This research brief presents the results of a survey of Maine’s large forest owners and managers. Our findings indicate a need for clear policies and collaborations between forest organizations to prepare for a SBW outbreak. While many forest organizations use satellite imagery, personnel capacity and lack of knowledge are barriers to using remote sensing. We recommend strengthening forest health programs by hiring a …

Ambrosia Beetle (Coleoptera: Curculionidae: Scolytinae) Responses To Ice Storm Damage In Mesic, Mixed Deciduous Forests In Southeast Ohio, United States, Christopher J. Hayes, Richard M. Turcotte

The Great Lakes Entomologist

In the eastern United States abiotic forest disturbances are common and cause extensive tree damage. Freshly broken trees and tree branches attract bark and ambrosia beetles that utilize inner bark and xylem of damaged branches and trees to fill requisite habitat needs. An ice storm in February 2003 on the Wayne National Forest presented an opportunity to study the local ambrosia beetle species and their reaction to this storm event. Ethanol baited Lindgren traps were deployed from 2003-2006 starting in the summer after the storm. Eight native and introduced Scolytinae ambrosia beetle species were trapped in large numbers (>500 …

Tree Diversity Across The Minneapolis-St. Paul Metropolitan Area In Relation To Climate And Social Vulnerability, Adrienne B. Keller, Leslie A. Brandt, Jeannine Cavender-Bares, Joseph F. Knight, Sarah E. Hobbie

Michigan Tech Publications, Part 2

Urban tree canopy cover is often unequally distributed across cities such that more socially vulnerable neighborhoods often have lower tree canopy cover than less socially vulnerable neighborhoods. However, how the diversity and composition of the urban canopy affect the nature of social-ecological benefits (and burdens), including the urban forest's vulnerability to climate change, remains underexamined. Here, we synthesize tree inventories developed by multiple organizations and present a species-specific, geolocated database of more than 600,000 urban trees across the 7-county Minneapolis-St. Paul (MSP) metropolitan area in the Upper Midwest of the United States. We find that tree diversity across the MSP …

An Automated Machine Learning Approach To The Retrieval Of Daily Soil Moisture In South Korea Using Satellite Images, Meteorological Data, And Digital Elevation Model, Nari Kim, Soo-Jin Lee, Eunha Sohn, Mija Kim, Seonkyeong Seong, Seung Hee Kim, Yangwon Lee

Institute for ECHO Articles and Research

Soil moisture is a critical parameter that significantly impacts the global energy balance, including the hydrologic cycle, land–atmosphere interactions, soil evaporation, and plant growth. Currently, soil moisture is typically measured by installing sensors in the ground or through satellite remote sensing, with data retrieval facilitated by reanalysis models such as the European Centre for Medium-Range Weather Forecasts (ECMWF) Reanalysis 5 (ERA5) and the Global Land Data Assimilation System (GLDAS). However, the suitability of these methods for capturing local-scale variabilities is insufficiently validated, particularly in regions like South Korea, where land surfaces are highly complex and heterogeneous. In contrast, artificial intelligence …

Building Gender Equity In Forestry Education: The Benefits Of Oregon’S Women Owning Woodlands Network, Lauren A. Grand, Tiffany Hopkins Sep 2024

Building Gender Equity In Forestry Education: The Benefits Of Oregon’S Women Owning Woodlands Network, Lauren A. Grand, Tiffany Hopkins

The Journal of Extension

The Women Owning Woodlands Network was launched in 2005 as a way to provide collaborative and hands-on peer learning education to women who felt uncomfortable participating in traditional Extension programs. Since its inception the program as grown to provide education and resources for over 300 women. We surveyed these women to identify if the program continues to meet their needs. It is evident that WOWNet has continued to be an important part of OSU FNR’s outreach education program and continues to meet the needs of a historically undeserved group of landowners in ways that traditional programming does not.

The Cooperative Extension Service delivers informal educational programs that can help to improve the lives of citizens and communities. Planning, design, implementation, and evaluation are crucial considerations for Extension programs and serve as the foundation for the Extension Program Development Model. The Extension Program Development Model has underlying assumptions that may not be explicitly stated or apparent to Extension practitioners, but if the assumptions are violated, it can lead to cascading effects that impact the effectiveness of an Extension program. This paper will discuss the assumptions of the Extension Program Development Model and the potential impacts of assumption violations. We …


Exploring The Multifunctional Landscapes Model In Areas Dominated By Non-Native Tree Plantations, Andrea Monica D. Ortiz, Eugenia M. Gayó, Noelia Carrasco Henríquez, Bárbara Jerez Henríquez, Aníbal Pauchard Sep 2024

Exploring The Multifunctional Landscapes Model In Areas Dominated By Non-Native Tree Plantations, Andrea Monica D. Ortiz, Eugenia M. Gayó, Noelia Carrasco Henríquez, Bárbara Jerez Henríquez, Aníbal Pauchard

SOSE Affiliate: Manila Observatory

Multifunctional landscapes offer an integrated approach to production, conservation, and human well-being. However, the challenges of implementing them in territories where plantations dominate are yet not well understood. This is the case in Chile, where plantations of non-native pines and eucalypts are extensively planted in its South-Central regions for timber and pulp. The resulting landscape homogenization, environmental degradation, and increased wildfire risk have caused and exacerbated conflicts, impacting biodiversity and the well-being of local communities and the Indigenous Mapuche Peoples. After the mega-wildfires in the region in 2023, science-policy discourse promoted the multifunctional landscapes model as a way to increase …

Understanding The Impact Of The Covid-19 Pandemic On Participation In Maine's Outdoor Recreation And Nature-Based Tourism, Lucy Martin

Electronic Theses and Dissertations

The COVID-19 pandemic has had an unprecedented effect especially industries like tourism that rely heavily on transportation and mobility. The state of Maine’s economy is supported by nature-based tourism and visitors to Maine commonly seek outdoor recreation opportunities when visiting. As the pandemic progressed, Maine recommended outdoor recreation as a means of socializing safely which increased interest for outdoor recreation and nature-based tourism. Being outdoors does not eliminate the likelihood of contracting COVID-19 therefore individuals’ risk perceptions impact their participation in outdoor recreation and travel behavior. Furthermore, institutional encouragement created new users that may have different expectations and understandings when …


Scaling, Modeling, And Resilience Of The Arctic Boreal Ecosystem, Wouter Hantson Aug 2024

Scaling, Modeling, And Resilience Of The Arctic Boreal Ecosystem, Wouter Hantson

Electronic Theses and Dissertations

Arctic tundra landscapes are characterized by underlying permafrost sustained by extremely low average temperatures. These permafrost soils have been sequestering carbon for millennia, effectively locking it into the frozen ground. Currently, anthropogenic climate change, exacerbated by Arctic amplification, is driving rapid and unprecedented warming in the Arctic region putting the permafrost at risk of thaw. Thawing permafrost could release vast amounts of previously stored carbon as greenhouse gasses, driving the permafrost carbon feedback to accelerate warming. Unfortunately, the high spatial variability and complex feedback mechanisms limit our understanding of the connections and dynamics between above- and below-ground processes, and current …

Tick-borne diseases have been a rising threat to public health. Maine is experiencing a continued north and westward migration of Lyme disease into the state and increasing numbers of cases year after year (Rosenberg et al., 2018). Maine’s economy has a high reliance on the tourism industry, with a focus on outdoor recreation (Maine Office of Tourism, 2018), and the future success of this sector may be threatened by the risk that Lyme disease poses. One’s perception of risk is known to be influenced by the information available around them (Kasperson et al., 1988). Thus, it is pertinent that we …


Effects Of Personality On Cache Pilferage And Activity Patterns In Maine's Forest-Dwelling Small Mammals, Brigit R. Humphreys Aug 2024

Effects Of Personality On Cache Pilferage And Activity Patterns In Maine's Forest-Dwelling Small Mammals, Brigit R. Humphreys

Electronic Theses and Dissertations

Personality, or the tendency for individuals to behave consistently, has been observed throughout the animal kingdom and is known to have key ecological and evolutionary consequences. Because different personalities play distinct roles in a community, it is critical to understand which personalities are more likely to complete vital ecosystem functions, and how anthropogenic land-use change may influence personality compositions of a population. The purpose of my research is to contribute to filling these knowledge gaps, using forest-dwelling small mammals as a model system. Small mammals such as mice and voles play a fundamental role in the ecosystem service of seed …


Chinese Tallow Long-Term Impact On Stand Dynamics In A Bottomland Hardwood Forest Following Vegetation Management, Nicklaus R. Langlois Aug 2024

Chinese Tallow Long-Term Impact On Stand Dynamics In A Bottomland Hardwood Forest Following Vegetation Management, Nicklaus R. Langlois

Electronic Theses and Dissertations

Chinese tallow (Triadica sebifera (L.) Small) is an invasive tree known to have negative impacts on bottomland hardwood forests. Chinese tallow is proficient in reproducing and surviving in bottomland hardwood forests because it is more flood and shade tolerant than most native trees. The long-term effectiveness of Chinese tallow control is an important topic to research as only a few long-term studies of Chinese tallow control have been conducted. A 10-year re-measurement of 22 paired plots installed in 2012 on the Pineywoods Mitigation Bank near Diboll, Texas following herbicide treatments examined Chinese tallow and native tree stand structure. Each …
