Quantifying The Role Of Water Quality On Nitrogen Cycling In A Trophic Estuary, Kayla Gonzalez-Boy Nov 2023

Quantifying The Role Of Water Quality On Nitrogen Cycling In A Trophic Estuary, Kayla Gonzalez-Boy

Symposium of Student Scholars

Jobos Bay Estuary is an intertidal, tropical estuary located in southern Puerto Rico. The estuary covers about 12 km2 and has a variety of habitats, such as seagrass beds, mangroves, mud flats, and coral reefs, which play important roles in sediment trapping and water quality maintenance. Seagrasses also serve as nursery and feeding grounds and provide shelter for macrofauna. Currently, the role of seagrasses and water quality on nitrogen (N) cycling in trophic estuaries is not well constrained. Understanding variations in sediment-based effects on N cycling rates and transformations, and how they are associated with water quality, is an …

Lichens Of Iller Creek: A Checklist For The Iller Creek Unit, A Division Of Dishman Hills Conservation Area, Spokane Valley, Wa, Devin M. Mumey, Giovanna Bishop, Jessica L. Allen

2023 Symposium

The field of biodiversity documentation encompasses a broad range of research including new species discovery and description, compilation of species present in a given area, and investigation of interspecies interaction. In an era of increasingly devastating and rapid environmental change, documenting biodiversity has become increasingly important. Anthropogenic effects on urban-adjacent natural areas are especially significant, as they can cause numerous, often drastic, responses in ecosystems. Our objective here was to document the lichen biodiversity in a large urban-adjacent protected area: the Iller Creek Unit of the Dishman Hills Conservation Area in Spokane Valley, Washington. This unit encompasses a diversity of …


Developing Cryopreservation Methods Of Wheat Roots, Ramanpreet Singh, Nguyen Khoi Nguyen, Taylor S. Matteucci Sep 2023

Developing Cryopreservation Methods Of Wheat Roots, Ramanpreet Singh, Nguyen Khoi Nguyen, Taylor S. Matteucci

2023 Symposium

In the midst of record breaking rates of plant species extinction due to climate change and fungal diseases, a universal cryopreservation method would provide a means for preservation of these many different species. The concept of plant root cryopreservation first emerged in the late 1960’s, and with it came new avenues of preserving tissue for the purposes of agriculture and research. Frozen tissues can be transported and stored more reliably than other more conventional means. When thawed, they have the potential to be cultured and grown. Several different methods of cryopreservation exist. This experiment used the Fast (3°C/minute) and Slow …

Linking Soil Properties to Originally Wooded and Afforested Areas

Matthew Laun, Ashton Crowe

Mentor: I. P. Handayani

Hutson School of Agriculture Murray State University, KY, USA

Abstract

Afforestation, adding an artificial forest to a piece of land that has been barren of trees for a significant amount of time, has some seriously huge impacts on the environment. These effects can be seen as an increase in the soil organic matter, a decrease in compaction, and enhancement of porosity. Therefore, the soil can support more diverse microbes and fungal communities leading to better micro and macro nutrient transfers between plants. This …

Microbial Diversity And Community Structure In Sediments Associated With The Seagrass (Thallassia Testudinum) In Apalachicola Bay, Florida, Rahma Ahmed, Thomas Mcelroy, Troy Mutchler Apr 2022

Microbial Diversity And Community Structure In Sediments Associated With The Seagrass (Thallassia Testudinum) In Apalachicola Bay, Florida, Rahma Ahmed, Thomas Mcelroy, Troy Mutchler

Symposium of Student Scholars

Seagrass is an angiosperm which provides many ecosystem services in coastal areas, such as providing food, shelter and nurseries for many species, and decreasing the impact of waves on shorelines. A global assessment reported that 29% of known seagrass meadows are in a state of decline due to the effects of human activity. Seagrass is commonly found in shallow marine waters where they form meadows containing a microbiome that plays an important role in providing nutrients for seagrass growth, though little is known about the microorganisms within the seagrass meadow sediments. Our project collected sediments from seagrass meadows and adjacent …


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 …


A Quantitative Analysis Of The Effects Of Urbanization, Mesophication And Prescribed Burns On Oak Woodlands In The Chicago Metropolitan Area, Chad Populorum May 2018

A Quantitative Analysis Of The Effects Of Urbanization, Mesophication And Prescribed Burns On Oak Woodlands In The Chicago Metropolitan Area, Chad Populorum

Celebration of Learning

Urban expansion has had devastating impacts on forest ecosystems, especially within the past century. Human attempts to dominate nature have diminished natural disturbance regimes, which have maintained the biodiversity and historic composition of these ecosystems. Fires have been a prominent force in maintaining the structure of oak, hickory and other heliophytic (sun loving and fire-adapted) forest systems. Human induced fire suppression has led to mesophication across North America. Mesophication is the transition from drier conditions with open canopies to wetter conditions with closed canopies. These new conditions decrease the survival rates of these important species and begin to favor mesophytic …


Utilizing Gis To Locate Endangered Gravel Hill Prairies Of The Wabash River Valley, Ryan W.R. Schroeder Jan 2018

Utilizing Gis To Locate Endangered Gravel Hill Prairies Of The Wabash River Valley, Ryan W.R. Schroeder

Engagement & Service-Learning Summit

The Gravel Hill Prairies (GHP’s) of the Wabash River Valley are an endangered ecosystem in the state of Indiana and provide optimal growing conditions for a number of state endangered plants. Currently only four remnants are known to exist near Lafayette, IN, found by a previous study conducted in 1980 by Post, Bacone, and Aldrich (Proceedings of the Indiana Academy of Science, 1984, vol. 94: 457-464). These unique ecosystems have been found to occur almost exclusively on soils classified as Rodman Gravelly Loams and Strawn-Rodman complexes which occur predominantly along the outwash terraces of the Wabash River and its tributaries. …


Expanding Access To Biodiversity Literature, Patrick Randall May 2017

Expanding Access To Biodiversity Literature, Patrick Randall

Digital Initiatives Symposium

Expanding Access to Biodiversity Literature (EABL) is an IMLS-funded grant designed to enhance the collection of the Biodiversity Heritage Library (BHL), a digital library providing open access to over 50 million pages of legacy biodiversity literature.

BHL's collection is built on the digitized holdings of its member libraries, typically large research universities, natural history museums, and other well-funded organizations. EABL, however, solicits content outside the BHL consortium; small organizations that often lack the resources for cataloging and digitization nevertheless have valuable and unique literature to contribute. This has created new challenges for BHL workflows, as well as opportunities for novel …


Mapping Morels: Predicting The Locations Of Morchella Species Through Environmental Factors Using The Gis System, Emily M. Stanevicius Jun 2016

Mapping Morels: Predicting The Locations Of Morchella Species Through Environmental Factors Using The Gis System, Emily M. Stanevicius

Celebration of Learning

Morel mushrooms, Morechella esculenta and M. deliciosa, are known delicacies across the globe, ranging from exquisite dishes in French cuisine to Eastern palates such as Japanese Matsutake. According to literature, true morels diverged as their own genus about 129 million years, again which has led to the development of more than 177 species and have been part of the human diet since their beginning. However, the elusiveness of morels has contributed to the mushrooms infamy for rarity, and has even been known to sell for more than $40 per pound. This project seeks to aid in the search for morels …

Incorporating Satellite Derived Cloud Climatologies To Improve High Resolution Interpolation Of Daily Precipitation., Adam M. Wilson, Benoit Parmentier, Brian Mcgill, Rob Guralnick, Walter Jetz

Yale Day of Data

Conservation of biodiversity demands comprehension of evolutionary and ecological patterns and processes that occur over vast spatial and temporal scales. A central goal of ecology is to understand the factors that control the spatial distribution of species and this has become even more important in the face of climate change. However, at global scales there can be enormous uncertainty in environmental data used to model species distributions. Even ‘simple’ metrics such as mean annual precipitation are difficult to estimate in areas with few weather stations and available data sets do not quantify uncertainty in these surfaces. We are developing a …
