Relationships Between Alternative Visual Methods To Quantify Tree Reproduction, Riley Adams
2023 Midwest Ecology & Evolution Conference
Many tree species have extremely high variability in their magnitude of reproduction over space and time. Annual seed crop variation in trees affects forest regeneration, and the seeds influence animal reproduction and wildlife population dynamics in numerous species (e.g., birds, mammals, and insects). The number of reproductive structures on trees is commonly estimated by varying visual counting methods, from categorical classifications as done by the National Phenology Network, to timed counts and counts of all visible reproductive structures. Different methods may produce different findings, and with recent multi-species databases, constructed on tree reproduction and for future projects, variation across methods …

Forest Recruitment Dynamics Within The Southern Boreal-Temperate Ecotone, Kiley M. Chernicky
2023 Midwest Ecology & Evolution Conference
Understanding how global climate change will alter future forest composition is especially challenging in forest communities where tree species have long co-occurred, but their competitive balance may be altered due to changes in climate. Of particular concern with increasing global temperatures are boreal forest communities that lie on the southern boreal-temperate forest ecotone, where the boreal forest is particularly vulnerable. The aim of my research is to investigate shifts in recruitment dynamics due to climate change near the southern range limit of two historically co-occurring boreal forest conifer species, white spruce (Picea glauca) and balsam fir (Abies …

Effect Of Variable Canopy Cover On Floral Visitation, Toby Shaya
2023 Midwest Ecology & Evolution Conference
Pollinators provide essential services for ecosystem function. Studies aimed at understanding how availability of floral resources impacts pollinators find that canopy cover impacts bees indirectly by affecting the amount of floral resources in the forest understory and directly by changing the thermal environment in which they can thermoregulate. As ectotherms the maintenance of bee body temperature depends on the distribution of patches of sun and shade throughout a landscape, which can be dependent on canopy cover. The goals of this study were to understand how variable canopy cover drives floral visitation patterns in oak savanna found in the Oak Openings …

Phosphours Trasnport In Soil: Locating And Identifying A Limiting Element, Jeremy Giannone
2023 Midwest Ecology & Evolution Conference
The phosphorus (P) cycle is not well understood. While carbon (C) and nitrogen (N) have gas phases, P does not. Phosphorus runoff in waterways and its shortage are both understood since their causes are due to agricultural demands. Fertilizers increase the rate of phosphorus in the soil leading to greater runoff which then accumulates in the surrounding bodies of water.1 From an economic perspective the phosphorus availability and food prices have a direct correlation. The instability of phosphate prices may have direct causation to the instability of the food and agriculture markets.2In order to deal with these …

Mycorrhizal Fungi And Reforestation In An Eastern Lowland Rainforest Of Madagascar, Sophia Gibby
Independent Study Project (ISP) Collection
Most terrestrial plants worldwide make associations with mycorrhizal fungi, yet the fungal diversity of Madagascar is vastly unknown. This research project is a preliminary investigation into the mycorrhizal status of 19 tree species in and near Ranomafana National Park (RNP), a lowland tropical forest on the southeast coast of Madagascar. Arbuscular mycorrhizal (AM) colonization in these species was studied in root samples under the microscope in the laboratory of Centre ValBio (CVB). The degree of AM infection was assessed for three study areas: one directly adjacent to a protected area and two reforestation sites supported by CVB. For the 19 …

Understory Epiphyte Hydrology: Analyzing Water Storage Capacity Of Epiphytes Along An Elevational Gradient In Western Ecuadorian Cloud Forest, Angelina Dodge
Independent Study Project (ISP) Collection
Epiphytes are defined as plants that grow on a host, often another plant, and acquire their nutrients and water from the atmosphere. As such is true, epiphyte composition is largely dependent upon atmospheric and thus climactic conditions. Due to high levels of atmospheric water availability that results from the frequent presence of mist, clouds, and high humidity, epiphytic plants grow and thus store water within the above ground region of the Andean cloud forest at levels higher than in any other ecosystem found in Ecuador. This study was done in hopes of revealing any trends of epiphytic water storage capacity …

Tropical Tree Carbon Storage At Drago Dos Forest In Boca Del Drago, Panama, Ben Dwyer
Independent Study Project (ISP) Collection
Currently, anthropogenic carbon emissions pose a significant, global threat, contributing to Global Warming and Climate Change (CC). Today, the most effective carbon sinks are natural. Trees are highly effective carbon sinks that sequester large amounts of atmospheric carbon dioxide (CO2), most greatly in tropical areas. However, tropical tree carbon storage needs to be more accurately estimated to provide valuable information toward mitigating CC and its negative environmental effects. This study aimed to estimate CO2 sequestration at a tropical forest in Boca Del Drago, Panama, and compare it to that of a nearby mangrove forest. It was hypothesized that the tropical …

Variation In The Growth Parameters And Biomass Of Rhizophora Mangle Seedlings With Distances From Playa Estrella, Bocas Del Toro, Panama, Thiny Tep
Independent Study Project (ISP) Collection
Mangrove is a salt-tolerant, intertidal, tropical tree or shrub and make up a rich community of various organism. On the Caribbean coast of Panama, in Bocas del Toro, mangrove forests cover 28 km2 and are dominated by R. mangle, followed by L. racemosa and A. germinans. Simultaneously, Isla Colón, the most populated and developed among all islands in the Bocas del Toro Archipelago, is a tourist center. Unfortunately, tourism comes at the price of environmental degradation via alteration of natural habitats, solid and wastewater pollution. Therefore, this study aims to gain a preliminary understanding on how the …

Troop Composition And Behavior Of Mantled Howler Monkeys (Alouatta Palliata) In Mangroves And Forested Islands South Of David, Panama, Slate Hyacinthe
Independent Study Project (ISP) Collection
The mantled howler monkey, Alouatta palliata, is one of the most commonly studied and widely distributed primate species in Central America. They have been reported to inhabit mangrove environments in Panama, but few studies have undertaken to describe their demography and behavior in these particular ecosystems. For my study, I spent 12 days studying A. palliata populations in both the mangrove and forested island ecosystems (Isla Parida and Isla Boca Brava) south of David. Seven groups were found in the mangrove environments, and 11 groups were found on the island environments. The mangrove groups were significantly smaller and at a …

Agroforestry For The Future: Motivations Behind Tasmanian Farmers Planting Trees, Josh Lipp
Independent Study Project (ISP) Collection
Agroforestry is the act of combining farming and tree planting, and many Tasmanian farmers are starting to plant trees on their properties for multiple reasons. Through conducting 9 interviews with farmers and researchers and visiting field sites, 3 main themes were identified to answer the question: why are Tasmanian farmers planting trees, and what are the benefits and downsides to agroforestry? Interviews help us understand farmers’ perceptions of agroforestry, and field data collection will prove the benefits of agroforestry in the future. Tasmania was chosen as the location of study as it is a state in Australia that largely focuses …

An Examination Of The Current Knowledge Of Contaminants In Mangroves: Hawaii And Globally, Geoffrey Szafranski
Environmental Science and Management Professional Master's Project Reports
The geographic range of mangrove forests is shifting quickly as they expand poleward in response to climate change while simultaneously being removed from their native extent to clear space for anthropogenic land-uses. Mangrove forests are also known to be sinks for anthropogenic contamination. Yet contamination research is under-researched in mangrove ecosystems, specifically the environmental fate, effect on biodiversity, and risk to human populations from contamination in the context of these changing conditions requires further research. The goal of this thesis is to address this data gap through analysis of contamination in the literature and through an investigational survey of mangrove …

Community Participation And Perspectives Of Ambondrolava Mangrove Restoration Project, Nadine Shannon
Independent Study Project (ISP) Collection
Madagascar’s mangrove forests are intertidal ecosystems that provide numerous valuable ecosystem services but are nonetheless under pressure from large amounts of deforestation. On the southwestern coast of Madagascar, the village of Ambondrolava practices community led management of the mangrove and its resources. This research project studied the evolution of the mangrove area using GIS data, and investigated, through interviews, the relationship between the local community of Ambondrolava and the organizations that manage the mangrove ecosystem. From 2000 to 2018, the zone of the mangrove has experienced a net loss in area every year, despite reforestation efforts. Most community members interviewed …

Journal of Bioresource Management
The inventory of the carabid family at two forest sites in the Belezma national park namely an oak grove site and a cedar site during a period ranging from May 2017 to April 2018, has shown the counting of 27 taxa that have been inventoried by Barber pitfall traps. The results showed that the Quercus ilex site has slightly more species (25 species) compared to the Cedrus atlantica one (23 species). However, the Harpalinae subfamily is quantitatively the better one represented at both sites. The Shannon and Simpson indices report slightly higher figures in the Cedrus atlantica site with respectively …

Less Fuel For The Next Fire? Short-Interval Fire Delays Forest Recovery And Interacting Drivers Amplify Effects, Kristin H. Braziunas, Nathan G. Kiel, Monica G. Turner
Aspen Bibliography
As 21st-century climate and disturbance dynamics depart from historic baselines, ecosystem resilience is uncertain. Multiple drivers are changing simultaneously, and interactions among drivers could amplify ecosystem vulnerability to change. Subalpine forests in Greater Yellowstone (Northern Rocky Mountains, USA) were historically resilient to infrequent (100–300 year), severe fire. We sampled paired short-interval (<30-year) and long-interval (>125-year) post-fire plots most recently burned between 1988 and 2018 to address two questions: (1) How do short-interval fire, climate, topography, and distance to unburned live forest edge interact to affect post-fire forest regeneration? (2) How do forest biomass and fuels vary following short-interval versus long-interval severe fires? …

Regeneration Strategies And Forest Resilience To Changing Fire Regimes: Insights From A Goldilocks Model, Tanjona Ramiadantsoa, Zak Ratajczak, Monica G. Turner
Aspen Bibliography
Disturbances are ubiquitous in ecological systems, and species have evolved a range of strategies to resist or rebound following disturbance. Understanding how the presence and complementarity of regeneration traits will affect community responses to disturbance is increasingly urgent as disturbance regimes shift beyond their historical ranges of variability. We define "disturbance niche" as a species' fitness across a range of disturbance sizes and frequencies that can reflect the fundamental or realized niche, that is, whether the species occurs alone or with other species. We developed a model of intermediate complexity (i.e., a Goldilocks model) to infer the disturbance niche. We …

We revisit the nature and extent of trophic cascades and quaking aspen (Populus tremuloides) recovery in the northern range of Yellowstone National Park (YNP), where studies have reported on Rocky Mountain elk (Cervus canadensis) browsing and young aspen heights following the St. John, 1995-96 reintroduction of gray wolves (Canis lupus). A recent study by Brice et al. (2021) expressed concerns about methodologies employed in earlier aspen studies and that results from those studies exaggerated the extent to which a trophic cascade has benefitted aspen, concerns such as: (a) the selection of aspen stands, (b) …
