Investigating The Role Of Plant Traits And Interactions In Emergent Wetland Nutrient Removal, Andrew Ryan Sample Aug 2023

Investigating The Role Of Plant Traits And Interactions In Emergent Wetland Nutrient Removal, Andrew Ryan Sample

Theses and Dissertations

Increasing wetland restoration in the Lower Mississippi Alluvial Valley has been identified as a method to reduce nutrient loading in the Gulf of Mexico. Wetlands have historically been used to treat water through processes facilitated by wetland plants, and relatively few species and plant traits have been identified as important in carrying out these processes. This study focuses on some of those species and traits and aims to identify species differences and plant traits that may be important for wetland nutrient mitigation. Chapter I provides background information on nutrient pollution, wetland biogeochemical mechanisms for nutrient sequestration, and the focal species …

The Effects Of Dormant Season Burning And Flooding On Invasive Cattail, Typha X Glauca, On Rainy Lake And Lake Kabetogama In Northern Minnesota, Erika Meints Aug 2023

The Effects Of Dormant Season Burning And Flooding On Invasive Cattail, Typha X Glauca, On Rainy Lake And Lake Kabetogama In Northern Minnesota, Erika Meints

All NMU Master's Theses

Typha x glauca is one of the most invasive plants in North America. The plant exhibits hybrid vigor and displaces native flora by rapidly forming dense monotypic stands that can break free from the substrate and form floating mat types when established. I tested the effects of prescribed burning, on Typha x glauca in wetlands to adjacent large lakes in Voyageurs National Park in northern Minnesota. My team surveyed four wetlands that were burned in late winter of 2020-21, and six that were unburned controls. Pre-burn data was also collected for all ten wetlands. Pre-flooding data from other wetlands within …

Mowing Cattail Cover To Increase Aquatic Vegetation Diversity On The Coeur D’Alene River Floodplain In Cataldo, Idaho, Makenna J. Tabino May 2023

Mowing Cattail Cover To Increase Aquatic Vegetation Diversity On The Coeur D’Alene River Floodplain In Cataldo, Idaho, Makenna J. Tabino

2023 Symposium

The Schlepp Easement is a 400 acre wetland on the Coeur D’Alene River floodplain, near Cataldo, Idaho. The wetland has been restored to protect it from heavy metal pollution transported downstream from mining sites near Kellogg, Idaho, the location of the Bunker Hill EPA Superfund Site. This wetland was restored to provide safe habitats and feeding grounds for migratory waterfowl and to maintain wetland biodiversity. However, cattail is prone to becoming overdominant and outcompeting other plants, which greatly limits a wetland’s biodiversity. Our objectives were to test whether aquatic boat mowing can reduce cattail cover, improving species diversity and cover …

Floodplain Forest Regeneration Dynamics In The Lower Mississippi River Alluvial Valley, Whitney Anne Kroschel Jul 2020

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 …

Vascular Flora Of Adobe Valley And Surrounding Hills, Mono County, California, Sophie E. Winitsky Jan 2020

Vascular Flora Of Adobe Valley And Surrounding Hills, Mono County, California, Sophie E. Winitsky

Aliso: A Journal of Systematic and Floristic Botany

Adobe Valley and the Adobe Hills lie east of the Sierra Nevada in Mono County, California, and are within the Great Basin Floristic Province. The flora of Adobe Valley and the surrounding hills is influenced by the Great Basin Desert to the east, the Sierra Nevada to the west and the northern Mojave Desert to the south. Adobe Valley is surrounded by the Adobe Hills, Benton Range and Glass Mountain region, creating a circular closed basin with many small tributaries feeding into it. This topography contributes to the creation of a rare wetland complex, including alkali meadows, marshes, and lakes …

The Effects Of Woody Vegetation Encroachment And Removal Within A Coastal Fen, Joseph Saler Jan 2020

The Effects Of Woody Vegetation Encroachment And Removal Within A Coastal Fen, Joseph Saler

Cal Poly Humboldt theses and projects

Early successional wetland habitat is being lost in temperate regions worldwide as a result of changes in disturbance regimes that allow for the establishment and dominance of woody species. In particular, this phenomenon is pronounced in fens, which harbor high numbers of rare herbaceous species that require early successional habitat. I investigated the relationship between woody vegetation encroachment and herbaceous species diversity within a Northern California coastal fen that has been undergoing encroachment by woody vegetation for ca. 80 years by recording species richness and cover data from 338 permanent plots throughout the fen. I also investigated the effect of …

The Tensile Root Strength Of Emergent Coastal Macrophytes, Lauris Olivia Hollis Mar 2018

The Tensile Root Strength Of Emergent Coastal Macrophytes, Lauris Olivia Hollis

LSU Doctoral Dissertations

Spartina patens is a dominant emergent macrophyte in fresh, intermediate, and brackish marshes along the Atlantic and Gulf coasts of United States where its biomechanical properties are a key component of wetland health and resilience. Its root biomass and tensile root strength are essential for anchorage, erosion protection, and are important determinants of soil strength. Nutrients and the herbicide atrazine are suspected of negatively impacting this wetland plant and others. The objectives of this study were to: 1) ascertain the tensile root strength of five emergent coastal macrophytes in coastal estuaries, and 2) test the effects of nutrient addition, atrazine …

Wetland Invasion By Typha×Glauca Increases Soil Methane Emissions, Beth A. Lawrence, Shane Lishawa, Nancy Tuchman, Nia Hurst, Buck T. Castillo Nov 2016

Wetland Invasion By Typha×Glauca Increases Soil Methane Emissions, Beth A. Lawrence, Shane Lishawa, Nancy Tuchman, Nia Hurst, Buck T. Castillo

School of Environmental Sustainability: Faculty Publications and Other Works

Wetland invasion by monotypic dominant plants can alter the physicochemical and biological properties of soils that affect methane emissions, a potent greenhouse gas. We examined the effects of Typha × glauca invasion on soil methane using laboratory incubation and controlled mesocosm experiments. Typha-invaded soils collected from three Midwestern (USA) wetlands had greater methane production potential during laboratory incubation than soils dominated by native wet meadow vegetation. Ten years post-invasion of native plant-dominated mesocosms, Typha increased methane emissions at least three-fold (native: 15.0 ± 10.5 mg CH4-C m−2 h−1, median: 6.1 mg CH4-C …

Mapping Regional Inundation With Spaceborne L-Band Sar, Bruce Chapman, Kyle Macdonald, Masanobu Shimada, Ake Rosenqvist, Ronny Schroeder, Laura Hess

Publications and Research

Shortly after the launch of ALOS PALSAR L-band SAR by the Japan Space Exploration Agency (JAXA), a program to develop an Earth Science Data Record (ESDR) for inundated wetlands was funded by NASA. Using established methodologies, extensive multi-temporal L-band ALOS ScanSAR data acquired bi-monthly by the PALSAR instrument onboard ALOS were used to classify the inundation state for South America for delivery as a component of this Inundated Wetlands ESDR (IW-ESDR) and in collaboration with JAXA’s ALOS Kyoto and Carbon Initiative science programme. We describe these methodologies and the final classification of the inundation state, then compared this with results …

Bacon's Swamp- Ghost Of A Central Indiana Natural Area Past, Rebecca W. Dolan Jan 2014

Bacon's Swamp- Ghost Of A Central Indiana Natural Area Past, Rebecca W. Dolan

Scholarship and Professional Work - LAS

Bacon’s Swamp was identified in the 1920s as a ca. 12 ha glacial kettle lake bog system at the southernmost limits of these habitats in Indiana. Located just 9.6 km from the center of Indianapolis, the site was all but destroyed in the mid-20th century by urban expansion. Prior to habitat conversion at the site, Bacon’s Swamp was a frequent location for Butler University ecology class field trips and student research projects. Herbarium specimens and published inventory records allow for analysis of the historical vegetation of Bacon’s Swamp using modern techniques. Floristic Quality Assessment applied to these historical records reveals …

Diets Of Nesting Swainson's Hawks In Relation To Land Cover In Northwestern North Dakota, Robert K. Murphy Dec 2010

Diets Of Nesting Swainson's Hawks In Relation To Land Cover In Northwestern North Dakota, Robert K. Murphy

The Prairie Naturalist

Relationships between land use practices and types of prey used by Swainson's hawks (Buteo swainsoni) in the Northern Great Plains is of increasing interest as the quantity and quality of habitat in the region declines. I recorded 1,284 prey items at 18 Swainson' s hawk nesting areas throughout northwestern North Dakota during summer 1986-1987. After correcting for detectability biases and food needs of adults, I estimated (90% CI) 2,087-2,859 total prey individuals and 138.3-206.7 kg of prey biomass (x = 69.8 g/item) were consumed by adult and nestling Swainson's hawks during my study. Major prey (>10% overall …

Climatological Factors Influencing Yellow Perch Production In Semi-Permanent Wetlands, Christopher M. Longhenry, Michael L. Brown, Todd R. St. Sauver Jun 2010

Climatological Factors Influencing Yellow Perch Production In Semi-Permanent Wetlands, Christopher M. Longhenry, Michael L. Brown, Todd R. St. Sauver

The Prairie Naturalist

Climatological factors such as temperature, wind, and precipitation have been reported to affect fish reproduction and recruitment in large lakes; however, little is known about these relationships in shallow, semi-permanent wetlands. We utilized age-O yellow perch (Perca flavescens) aquacultural harvest data to model climate effects on variability of juvenile yellow perch year class strength in semi-permanent wetlands. Overall, March through May precipitation, April air temperature, and a wetland parameter (i.e., intrinsic characteristics) provided the best-supported model. These results potentially indicate that spring weather patterns have an influence on yellow perch year class strength in semi-permanent wetlands.

Habitat Characteristics Of Spring Blackbird Roosts In East-Central South Dakota, H. Jeffrey Homan, Richard S. Sawin, George M. Linz, William J. Bleier Sep 2006

Habitat Characteristics Of Spring Blackbird Roosts In East-Central South Dakota, H. Jeffrey Homan, Richard S. Sawin, George M. Linz, William J. Bleier

The Prairie Naturalist

In the northern Great Plains, blackbirds (Icteridae) roost almost exclusively in emergent-dominated wetlands. The physical characteristics of wetland roosts are not well understood. From March 20 to April 20, 1999, we studied 16 wetlands used as blackbird roosts in east-central South Dakota. Six wetlands had major roosts (range: 102,000-298,000 blackbirds); whereas, 10 wetlands had minor roosts (range: 2,010-34,000 blackbirds). Maximum roost size was correlated directly with emergent vegetation area (P = 0.05) and possibly with wetland basin area (P ≤ 0.10). Water depths were greater at used sites within wetlands of major roosts (median = 44 cm) than …
