The Effect Of Historic Shipwrecks On Sediment Microbiomes In The Northern Gulf Of Mexico, Melissa Brock 2019 University of Southern Mississippi

The Effect Of Historic Shipwrecks On Sediment Microbiomes In The Northern Gulf Of Mexico, Melissa Brock

Master's Theses

Microorganisms are ubiquitously distributed across all aquatic habitats, but it is the environmental conditions of a habitat that determine which microorganisms can thrive in terms of abundance or metabolic activity. Habitats that experience consistent physical and chemical environmental conditions repeatedly favor specific taxonomic groups which may result in a microbial assemblage that is commonly associated with that habitat (i.e., a core microbiome). Core microbiomes have been identified for a variety of natural marine habitats including methane seeps, wood falls, octocoral, and deep-sea sediments. However, it was unknown if the presence of man-made structures on the seafloor, including historic shipwrecks ...


Effects Of Water Table Depth And Edaphic Characteristics On Plant Diversity In A Southern Mississippi Pitcher Plant Bog, Patrick Kirby 2019 University of Southern Mississippi

Effects Of Water Table Depth And Edaphic Characteristics On Plant Diversity In A Southern Mississippi Pitcher Plant Bog, Patrick Kirby

Master's Theses

This study examined the effects that water table depth and soil characteristics have on plant species richness and species composition within pitcher plant bogs across seasons. Eight piezometers were installed at random distances to monitor long-term water table depth and pressure fluctuations along a ~710-meter line transect traversing upland and bog habitats. Vegetation sampling quadrats (n=128) were set up near each piezometer. Cover data and water table depths were collected in spring and late summer. Soil samples collected from each treatment group were used to obtain soil texture and nutrient data. The summer collection period yielded a total gdiversity ...


Spatial And Temporal Variation In The Aquatic Invertebrate Community Structure Of Rock Pools Along The Penobscot River, Maine, Chase R. Gagne 2019 University of Maine

Spatial And Temporal Variation In The Aquatic Invertebrate Community Structure Of Rock Pools Along The Penobscot River, Maine, Chase R. Gagne

Electronic Theses and Dissertations

Pools of water that form in the fissures and depressions of rock outcrops, known as rock pools, are fairly common aquatic habitats that can easily be found along the rocky banks of many of Maine’s major rivers. In general, rock pools and the aquatic invertebrates inhabiting them have received little research attention and, though ubiquitous, have never been studied in Maine. My research addressed this knowledge gap by surveying 40 rock pools at four sites along the Penobscot River in Maine. The rock pools themselves had highly variable environmental characteristics and differed across sites and over time, especially in ...

Changes In The Diet And Body Size Of A Small Herbivorous Mammal (Hispid Cotton Rat, Sigmodon Hispidus) Following The Late Pleistocene Megafauna Extinction, Catalina P. Tomé, Emma A. Elliott Smith, S. Kathleen Lyons, Seth D. Newsome, Felisa A. Smith

Faculty Publications in the Biological Sciences

The catastrophic loss of large-bodied mammals during the terminal Pleistocene likely led to cascading effects within communities. While the extinction of the top consumers probably expanded the resources available to survivors of all body sizes, little work has focused on the responses of the smallest mammals. Here, we use a detailed fossil record from the southwestern United States to examine the response of the hispid cotton rat Sigmodon hispidus to biodiversity loss and climatic change over the late Quaternary. In particular, we focus on changes in diet and body size. We characterize diet through carbon (δ13C) and nitrogen ...


Mammal Species Inventory Using Various Trapping Methods In Zone 4 Of Billy Barquedier National Park, Belize During Rainy Season, Mersady Redding 2019 University of Arkansas, Fayetteville

Mammal Species Inventory Using Various Trapping Methods In Zone 4 Of Billy Barquedier National Park, Belize During Rainy Season, Mersady Redding

Animal Science Undergraduate Honors Theses

Belize is a small country, but it is extremely ecologically diverse. Based on the few studies conducted in Belize, the abundance of mammals is low but diversity is high. Particular findings note the number and identity of species differed between four sites in the Maya Mountains of Belize, indicating that a data set from a single site is not representative of the Neotropical region. Insufficient data is available to estimate current species richness of many areas in Belize, including Billy Barquedier National Park (BBNP). The objective of this study was to explore trapping and documentation methods of terrestrial mammals in ...


Identity Of The Central American Scorpion Centruroides Mahnerti Lourenço, 1983 (Scorpiones: Buthidae), Luis F. de Armas 2019 Marshall University

Identity Of The Central American Scorpion Centruroides Mahnerti Lourenço, 1983 (Scorpiones: Buthidae), Luis F. De Armas

Euscorpius

The Central American scorpion Centruroides mahnerti Lourenço, 1983, was described on the basis of three female specimens (holotype and paratypes) from Momotombo Volcano, Nicaragua. Almost two decades later, it was synonymized under Centruroides koesteri Kraepelin, 1911 by Armas and Maes, without examination of the type specimen; but Teruel and Stockwell posteriorly argued that description and figures given for C. mahnerti are also similarly referable to juveniles of C. edwardsii (Gervais, 1843). Now, an evaluation of the holotype of C. mahnerti has definitively shown that it is a subadult female of C. koesteri. For the first time, photographs of the holotype ...

Both events included educational programs with informational walks and activities targeted to youth. In the fall, 654 species and 55 additional genera were recorded. In the spring, there were 581 species and 54 additional genera recorded. Two fungi and 38 lichens were first reports for Lowndes County; one fungus was a first for Georgia. One lichen may be a ...


#2 - Comparison Of Ion Transport Expression In Lake Sturgeon Exposed To Differing Water Chemistries, Caitlin Forkin 2019 University of West Georgia, Carrollton, GA 30118

#2 - Comparison Of Ion Transport Expression In Lake Sturgeon Exposed To Differing Water Chemistries, Caitlin Forkin

Georgia Undergraduate Research Conference (GURC)

This project investigated ion uptake by fish endemic to Georgia, known as Lake Sturgeon (Acipenser fulvescens), which were acquired from a hatchery and naturally found in the Coosa River. For this investigation, identical recirculating tank systems provided separated environments for the two types of water treatments. Equal test groups were placed into the different water chemistries, one into the Coosa River and the other into the regular dechlorinated tap water. All subjects consumed the same type of food: Rangen, which is a commercial chow mix, and blood worm. The Coosa River water differs in ionic composition compared to the hatchery ...

Comparing Plant Diversity on Animal Associations

Sean Eagan, Evan Lampert, Tom Diggs

It is known that climate change has an impact on community interactions and structure. Understanding the associations between plants and animals is pivotal to begin comprehending how future communities will be impacted. Competing hypothesis, with mixed results, have been previously tested on plant diversity and their associated herbivores. Oconee State Park located in South Carolina provides a range of ecosystems for comparison and understanding the community interactions between plants and their possible herbivores. Data collected using line transects and 16 quadrants respectively from four different ecosystems occurred in ...

#26 - A Comparison Of Benthic Invertebrates In The Etowah River 1958 & 2018, Rachel Pesaresi, Rachel Tempia, Gabriel Pierce, Jeremy Miller, Margi Flood, William Teitjen Dr.

Georgia Undergraduate Research Conference (GURC)

The Etowah River originates in Lumpkin County, northwest of Dahlonega. It flows south then west across North Georgia joining the Oostanala to form the Coosa River. It is famous for its biodiversity and is home to many threatened and endangered aquatic species.

Landscape use in North Georgia has changed in the past 100 years, shifting from agriculture to secondary regrowth of forests to increasingly large pockets of urbanization. This project examines benthic invertebrate composition change over sixty years in a small section of the Etowah.

Monthly benthic samples were taken at three locations in the section of the Etowah that ...

A New Species Of Kochius From Avra Valley, Southern Arizona (Scorpiones: Vaejovidae), Richard F. Ayrey, Lawrence L. C. Jones, Brandon Myers

Euscorpius

A new scorpion species, Kochius colluvius sp. n. is described (Scorpiones: Vaejovidae). This small brown species is found in the Avra Valley near Tucson, Arizona, USA. It appears to be most similar to Kochius sonorae (Williams, 1971) and K. hirsuticauda (Banks, 1910). On all fingers examined, the fixed finger has 6 ID denticles and the movable finger has 7. There is no scalloping of the chela fingers. This species differs from all other vaejovids in Arizona by having a coarsely granulated exoskeleton.

Wildlife Survey Of National Parks To Assess Reptilian Biodiversity, Ajk, Jibran Haider, Inayatullah Malik, Sabiha Shamim

Journal of Bioresource Management

The class Reptilia belongs to phylum Chordata. This group forms a large community of the land vertebrates. However, they remain relatively under-examined. Roll et al. (2017) studied the global distribution of more than 10,000 reptiles. Nearly194 reptilian species have been reported from Pakistan (WWF, n.d.). Five protected parks were studied from February 2008 to May 2010. Dhirkot Nature Reserve (DNR), Banjosa Nature Reserve (BNR), Tolipir National Park (TNP), Pir Chanasi National Park (PCNP) and Pir Lasura National Park (PLNP) were considered. Fifteen species of reptiles were observed in TNP. Ten species of reptiles were recorded from PCNP. Ten ...

Berberidaceae From Moist Temperate Forests, Northern Areas, Pakistan, Nafeesa Hanif Qudsia, Kishwar Sultana, Safdar Ali Shah

Journal of Bioresource Management

A quick visit of the protected forests of Banjosa, Dhirkot, Pir Chanasi, Pir Lassura and Tolipir was carried out. Berberidaceae belong to a family also known as the Barberry family (Elpel, n.d.). In Pakistan, there are 3 genera and 22 species belonging to this group (Jafri, n.d.). Species of this family are extensively cultivated due to their aesthetic and medicinal value. In the past, researchers would consider this family to get an idea about the habitat degradation of temperate areas. This study was aimed to produce a comprehensive list of species richness of this family in five National ...

A Preliminary Study On Population Of Some Passeriformes At Marala Head, Zahid Bhatti, Fakhra Nazir, Asad Ghufran

Journal of Bioresource Management

Passerines are perching birds of order Passeriformes representing half of the diversity of birds (Sibley and Monroe, 1990). There are total 6,600 species identified under 140 families declaring Passeriformes as the largest order of birds. Three hundred and thirteen species of Passeriformes were reported by Roberts (1992) from Pakistan but according to check list of birds of Pakistan there are more than 400 species of Passeriformes in Pakistan (Clements, 2019). They have significant ecological importance in an ecosystem and are mostly omnivores except the shrikes which are carnivorous. This study was done to form a preliminary checklist of Passeriformes ...


Drivers And Consequences Of Carbon Use Efficiency - And Its Measurement In Soil, Grace Pold 2019 University of Massachusetts Amherst

Drivers And Consequences Of Carbon Use Efficiency - And Its Measurement In Soil, Grace Pold

Doctoral Dissertations

Soils serve as massive carbon sinks, but their ability to continue this ecological service is contingent on how the resident soil microbial community will respond to the ongoing climate crisis. One key dimension of the microbial response to warming is its carbon use efficiency (CUE), or the fraction of carbon taken up by an organism which is allocated to growth rather than respiration. However, the scientific community is still in the early stages of understanding the drivers, consequences - and even accurate measurements of - CUE. In this dissertation, I first quantified the variability of CUE and its responsiveness to temperature and ...


Patterns Of Morphological Plasticity In Metriaclima Zebra And Danio Rerio Suggest Differently Canalized Phenotypes Due To Form-Function Relationships, Dylan Jockel 2019 University of Massachusetts Amherst

Patterns Of Morphological Plasticity In Metriaclima Zebra And Danio Rerio Suggest Differently Canalized Phenotypes Due To Form-Function Relationships, Dylan Jockel

Masters Theses

In order to ascertain the degree of compatibility in developmental restructuring and behavioral plasticity between two fish species frequently made subject of laboratory research (Metriaclima zebra & Danio rerio), alternative trophic niche exposure experiments utilizing novel three-prong feeding treatments were conducted to obtain morphometric data, which demonstrated both species do bear some degree of plasticity. The results are somewhat complicated by differences in locality of detectable restructuring, which may be due to disparity in the form-function relationship for each species’ lineage. Each is notable in the manner of respective species’ jaw protrusion, as it is driven by anterior kinethmoid rotation in ...


Cercarial Parasitism Of Freshwater Snails In Sandhills Ponds Versus Streams, Caroline Emily Spethman 2019 University of Nebraska - Lincoln

Cercarial Parasitism Of Freshwater Snails In Sandhills Ponds Versus Streams, Caroline Emily Spethman

Honors Theses, University of Nebraska-Lincoln

Parasite prevalence was calculated for all aquatic snails collected from four freshwater localities in Western Nebraska from Summer 2016 to 2019: Dunwoody Pond, Haythorn Ranch, Neven’s Restoration, and Breen’s Flyaway. With data of increasing trematode cercarial infection specifically at Dunwoody Pond, this community was further studied. In Summer 2019, a total of 217 freshwater snails representing species of Physa sp., Stagnicola elodes (Say,1821), and Helisoma anceps (Menke,1830) were collected from Dunwoody Pond and Dunwoody stream, near Ogallala, Nebraska. Eighty-one snails were collected from Dunwoody Pond, 76 snails were collected 31 meters upstream, and 60 snails were ...


The Effects Of Erosion Structures On Triplett Creek From The Fall Of 2016, 2017, And 2018, Haylee Winters 2019 Murray State University

The Effects Of Erosion Structures On Triplett Creek From The Fall Of 2016, 2017, And 2018, Haylee Winters

Posters-at-the-Capitol

Triplett Creek is a tributary of the Licking River. It runs through Morehead, KY, where we are conducting our research.

The creek was modified in the 1970s but construction was halted before the project was complete. Unfortunately, the result was an increase in overflow and subsequent riverbank erosion. The city installed sediment trap rocks in hopes of slowing down the water and decreasing erosion. We are using drones and photogrammetric software to map the area and compare images of the river to determine erosion rates. The new images will be compared to ones taken in previous years to visualize the ...
