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 ...
Seed Rain–Successional Feedbacks In Wet Tropical Forests, 2021 University of Nebraska - Lincoln
Seed Rain–Successional Feedbacks In Wet Tropical Forests, Nohemi Huanca Nuñez, Robin L. Chazdon, Sabrina E. Russo
Faculty Publications in the Biological Sciences
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 ...

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 ...

The Great Lakes Entomologist
Abstract. Overall, 409 Coleoptera species (369 identified to species, 24 to genus only, and 16 to subfamily only), representing 275 genera and 58 beetle families, were collected from late May through late September 2017 at the Grass River Natural Area (GRNA), Antrim County, Michigan, using baited multi-funnel traps (210 species), pitfall traps (104 species), and sweep nets (168 species). All three collecting methods were used in three distinct habitats: a rich conifer swamp (cedar), near the edge of a red pine plantation (pine), and within a mesic northern hardwood forest (hardwoods). Additional collections were made along two trails and in ...

Moderate Success With Underplanting 1-0 Containerized White Pine Seedlings In Shelterwoods With Abundant, Uncontrolled Understory Vegetation, Katherine Livingston
Dissertations and Theses
This study examined the six-year survival and growth response of underplanted 1-0 containerized white pine seedlings to site quality, overstory density, and scarification treatments in four shelterwoods on a high- and low-quality site with abundant, untreated, understory vegetation in the Adirondacks. Overall survival was 57% and was similar between site and overstory treatments. Scarification treatment reduced survival ,which was 63.9% in unscarified subplots and 50.3% in scarified subplots. Average seedling height and diameter across all treatments was 110.0 cm (43.3 in) and 1.7 cm (0.7 in), respectively. While site quality and scarification treatment had ...

Payment For Ecosystem Services: Rewarding The Landowner Who Conserves The Public Good, 2021 Stephen F. Austin State University, Arthur Temple College of Forestry and Agriculture
Payment For Ecosystem Services: Rewarding The Landowner Who Conserves The Public Good, Steven H. Bullard, Sarah Fuller
It has been said that money doesn’t grow on trees, but any forest landowner or manager will tell you that’s not exactly true— especially when observing a harvesting operation or managing dues from your hunting lease. While timber production and recreation are the most frequently monetized services provided by forests, what about the other goods and services they provide on a continuing basis? Are you or other forest landowners in your area being monetarily rewarded for soil stability, flood control, water filtration, air quality, and the other critical services—known as ecosystem services—provided by forests?

Resource allocation within trees is a zero-sum game. Unavoidable trade-offs dictate that allocation to growth-promoting functions curtails other functions, generating a gradient of investment in growth versus survival along which tree species align, known as the interspecific growth–mortality trade-off. This paradigm is widely accepted but not well established. Using demographic data for 1,111 tree species across ten tropical forests, we tested the generality of the growth–mortality trade-off and evaluated its underlying drivers using two species-specific parameters describing resource allocation strategies: tolerance of resource limitation and responsiveness of allocation to resource access. Globally, a canonical growth–mortality trade-off ...
Microsite Requirements For Successful Regeneration In Lowland Northern White-Cedar (Thuja Occidentalis) Forests, Jeanette Allogio
Electronic Theses and Dissertations
Declines in stands of northern white-cedar (Thuja occidentalis L., hereafter cedar) have been observed as both shifts in species composition and reductions in cedar densities, particularly those stands in lowland sites (Curtis 1946, Boulfroy 2012). While several factors inhibiting cedar regeneration have been identified, a thorough understanding of the conditions that best promote regeneration is lacking. Our objectives for the first chapter were to characterize the site conditions associated with successful regeneration in lowland cedar stands and to describe how spatial patterns of various cedar size classes relate to site preference and to regeneration dynamics. These objectives were achieved by ...

Filling Gender Gaps: Determining How Traditional Knowledge Of Lacandon Maya Women Shape The Diet And The Landscape In Lacanja Chansayab, Mexico, Lucía Pérez Volkow
Dissertations and Theses
Women’s knowledge and work in agroforestry food systems is poorly represented in the literature. I investigated women’s role in the food system, their relationship to food, and how Lacandon Maya women manage the landscape in Lacanja Chansayab, Mexico. Qualitative research included interviews and participant observation. Quantitative research included plant community surveys of plots managed by women and men. Women’s roles in food systems are central; they transform ingredients into meals and for agroforestry management. They express their relationship to food as a source of empowerment, as memory, a relationship to non-humans, and as a source of discrimination ...

Fostering Climate Change Resilience: A Socio-Ecological Forest Systems Approach, 2020 University of Maine
Fostering Climate Change Resilience: A Socio-Ecological Forest Systems Approach, Alyssa R. Soucy
Electronic Theses and Dissertations
As climate change continues to impact socio-ecological systems, those that rely on natural resources are highly sensitive to climatic changes. Maine’s forest industry provides for the economic and social well-being of many residents and is especially vulnerable to climate change impacts. Changes in growing season length and timing, forest health threats imposed by insects and pathogens, extreme weather events, shifting forest composition, and changes in natural disturbance severity and frequency have already begun, and are projected to continue, to impact forest systems in the Northeastern U.S. While climate change presents a threat to forest systems, opportunities also arise ...
Foliage Type Controls Mercury Input, Storage, And Release In The Boreal Forest, 2020 The University of Western Ontario
Foliage Type Controls Mercury Input, Storage, And Release In The Boreal Forest, Madelaine J R Anderson
Electronic Thesis and Dissertation Repository
Mercury (Hg) is a naturally occurring element with a complex biogeochemical cycle. Forests act as net sinks for both carbon (C) and Hg as foliage accumulates Hg with time. Litterfall represents a main input of C and Hg into forest soils. My aim was to investigate how foliage type (coniferous, deciduous) governs the input of Hg into forests with a field-based study that measured Hg accumulation over a growing season, and then investigate the storage and release of Hg from foliar tissues into soil with a laboratory-based incubation experiment. Results from the field-based study demonstrate deciduous leaves have more linear ...
The Impacts Of Prescribed Burning And Mechanical Thinning On Insect Communities In The Arkansas Ozarks, 2020 Arkansas Tech University
The Impacts Of Prescribed Burning And Mechanical Thinning On Insect Communities In The Arkansas Ozarks, Aaron P. Tormanen
Theses and Dissertations from 2020
Insects are important in woodland ecosystems due to their role as pollinators and as prey for bats. My research investigated the relationships between forest management, vegetation, and insects in the Ozark National Forest in Arkansas. I selected 30 stands burned at varying frequencies in the last 12 years. Twelve of these stands were burned and mechanically thinned, 12 were only burned, and 6 were untreated. I deployed blacklight traps and malaise traps in each stand monthly from mid-March to mid- November 2019. Over 42,391 insects were collected, and Lepidoptera was the most abundant order. Insects were dried, weighed, and ...
Ectomycorrhizal Plant-Fungal Co-Invasions As Natural Experiments For Connecting Plant And Fungal Traits To Their Ecosystem Consequences, Jason D. Hoeksema, Colin Averill, Jennifer M.

Introductions and invasions by fungi, especially pathogens and mycorrhizal fungi, are widespread and potentially highly consequential for native ecosystems, but may also offer opportunities for linking microbial traits to their ecosystem functions. In particular, treating ectomycorrhizal (EM) invasions, i.e., co-invasions by EM fungi and their EM host plants, as natural experiments may offer a powerful approach for testing how microbial traits influence ecosystem functions. Forests dominated by EM symbiosis have unique biogeochemistry whereby the secretions of EM plants and fungi affect carbon (C) and nutrient cycling; moreover, particular lineages of EM fungi have unique functional traits. EM invasions may ...
Floodplain Forest Regeneration Dynamics In The Lower Mississippi River Alluvial Valley, 2020 Louisiana State University and Agricultural and Mechanical College
Floodplain Forest Regeneration Dynamics In The Lower Mississippi River Alluvial Valley, Whitney Anne Kroschel
LSU Doctoral Dissertations
Floodplain forest species diversity is driven, in part, by variation in disturbance regime. Flood patterns create heterogeneity in microsite quality from small differences in elevation across a floodplain which, in turn, influence flood timing and duration. Differences in species’ regeneration niches in relation to hydrologic patterns can account for long-term coexistence of various species. In the past century floodplain forests have exhibited a wide range of changes in stand development and species composition as a result of altered hydrology in rivers and floodplains. I evaluated the role of regeneration in floodplain forest systems of the Lower Mississippi River Alluvial Valley ...

Retention Forestry Influences Understory Diversity And Functional Identity, Miranda T. Curzon, Christel C. Kern, Susan C. Baker, Brian J. Palik, Anthony W. D’Amato
Natural Resource Ecology and Management Publications
In recent decades, a paradigm shift in forest management and associated policies has led to greater emphasis on harvest practices that retain mature, overstory trees in forest stands that would otherwise be clear-cut. While it is often assumed that the maintenance of compositional and structural complexity, such as that achieved through retention forestry approaches, will also mitigate negative impacts to functional diversity, empirical evidence of this relationship is sparse. We examined the effects of an aggregated retention system on taxonomic and functional diversity in a regenerating aspen-dominated forest. Sampling was conducted along transects arranged to capture the transition from harvested ...
