Impacts Of Habitat Fragmentation On The Cranial Morphology Of A Threatened Desert Fish (Cyprinodon Pecosensis), Michael Chaise Gilbert

Masters Theses & Specialist Projects

Drastic alterations to the North American Southwest’s hydrology have highly influenced resident fish communities. In New Mexico and Texas, the Pecos River has been severely altered as a result of water manipulation, isolating backwaters and various habitats that were once connected to the main river. Cyprinodon pecosensis (Pecos pupfish) has been highly impacted due to the effects of anthropogenic water manipulation, as well as species introductions. Cyprinodon pecosensis populations have become isolated and scattered, residing in sinkholes, remnant lakes, and static backwaters, thus creating numerous micropopulations. The purpose of this study was to assess the morphological variation in cranial features …

Assessment Of American White Pelican Predation And Reproductive Success Of Walleye In The Tamarac River, Mn, Jake Graham

Biology Graduate Theses

The Tamarac River is a major tributary of the Red Lakes MN, which provides an economically important multispecies fishery. The river experiences spring spawning migrations of northern pike, walleye, and white suckers. However, limited data exists related to reproductive success of fishes in the river. Furthermore, in the previous decade large congregations of American white pelicans (AWPE) have been observed using the Tamarac River as a foraging ground each spring. Assessing reproductive success of fishes in the Tamarac River provides a more holistic understanding of fish ecology in the river and the importance of the Tamarac River to the Red …

Modulation Of Prey-Capture Kinematics And Suction Feeding Performance In Smallmouth Bass, Micropterus Dolomieu, Andrea Sejdic

Masters Theses & Specialist Projects

The feeding behavior of fishes is a topic that has piqued the interests of many researchers given the dynamic and ancestral nature of aquatic prey-capture. This study examines aquatic feeding in terms of the suction and ram components of feeding in smallmouth bass, Micropterus dolomieu, and how they modulate their kinematic behavior when attacking pelagic and benthic prey. Relative to other Micropterus genera, the reduced gape in smallmouth bass suggests they may create considerable suction pressure – stronger subambient pressure pulled through a smaller opening creates greater velocity. Suction feeding is useful when feeding on benthic prey, such as crayfish. …

Molecular Analysis Confirming The Introduction Of Nile Crocodiles, Crocodylus Niloticus Laurenti 1768 (Crocodylidae), In Southern Florida, With An Assessment Of Potential For Establishment, Spread, And Impacts., Michael R. Rochford, Kenneth L. Krysko, Frank J. Mazzotti, Matthew W. Shirley, Mark W. Parry, Joseph A. Wasilewski, Jeffrey S. Beauchamp, Christpher R. Gillette, Edward F. Metzger Iii, Michiko A. Squires, Louis A. Somma

Papers in Herpetology

The state of Florida, USA, has more introduced herpetofauna than any other governmental region on Earth. Four species of nonnative crocodilians have been introduced to Florida (all since 1960), one of which is established. Between 2000–2014 we field-collected three nonnative crocodilians in Miami-Dade County, Florida, and one in Hendry County, Florida. We used DNA barcoding and molecular phylogenetics to determine species identification and native range origin. Also, we described diet, movement, and growth for one crocodile. Our molecular analyses illustrated that two of the crocodiles we collected are most closely related to Nile Crocodiles (Crocodylus niloticus) from South Africa, suggesting …

Patterns Of Olfactory Neurogenesis And Immune Response In Adult Zebrafish Following Damage Of The Olfactory Bulb, Darcy M. Trimpe

Dissertations

The adult zebrafish olfactory system, with its persistent neuronal turnover and abundant regenerative capacity, is an excellent model system for studies of adult brain plasticity. Reversible deafferentation, achieved by repeated intranasal irrigation with detergent, reduces bulbar innervation and affects bulb structure and function, while cessation of treatment permits reinnervation and recovery of bulb volume. Alterations in cell genesis may account for this phenomenon. This study focuses on adult neurogenesis in the zebrafish olfactory system following reversible deafferentation and direct olfactory bulb injury.

Potential alterations in cell proliferation, differentiation, migration, and survival in the olfactory bulb following single and repeated intranasal …

Challenges And Opportunities In The Culture Of Giant Freshwater Prawn In The Philippines, Janice A. Ragaza

Biology Faculty Publications

Amid the irremediable decline of capture fisheries, the Philippine government has identified aquaculture as a sector that will ensure food security and generate new job opportunities geared toward the country’s goal of economic development (Nagothu and Ortiz 2007). Aquaculture of giant freshwater prawn Macrobrachium rosenbergii (Fig. 1) is an emerging program that is intended to expand and vary the aquatic species used in freshwater aquaculture, which is still predominantly based on tilapia (Rosario and Tayamen 2004). Attractive characteristics of freshwater prawn culture include ease of breeding, high hatching rate, superior quality of meat and high market value (Keysami and Mohammadpour …

Damsels In Distress: A Preliminary Assessment Of Pomacentridae Extinction Risk, Allison Roberts

Undergraduate Research Symposium

The family Pomacentridae is among the most diverse of the perciformes, boasting 400 different species of damselfish. These fish are found in coral reefs of varying depths around the world, most of which risk great damage due to climate change. In addition, many species are key components of the ornamental aquarium trade. Considering these threats, the importance of examining the state of Pomacentridae is paramount in examining the health of our oceans. Using IUCN Red List methods, preliminary data suggests some species of damselfish are at elevated risk of extinction.

Survival Of Walleye Eggs In Upper Red Lake And The Tamarac River, Phillip Oswald

Journal of Earth and Life Science

Walleyes experience spawning runs each spring in the Tamarac River, a tributary of the Red Lakes. However, data about walleye egg survival in the lake and river is lacking. Mesh cages were placed in both the Tamarac River and Upper Red Lake to compare survival rates. A total of twenty cages were set, ten in the river and ten in the lake. Each cage contained one hundred fertilized eggs which were checked every third day to measure survival. Temperature (°C), dissolved oxygen (mg/L), and pH were measured at each cage location. The river had an average survival rate of 22% …

Juvenile Survival And Adult Return As A Function Of Freshwater Rearing Life History For Coho Salmon In The Klamath River Basin, Molly Gorman

Cal Poly Humboldt theses and projects

The Scott and Shasta rivers, Klamath River tributaries, experience spatial disparity in habitat quality in spring and summer as a result of historical and current land-use. Juvenile Coho Salmon (Oncorhynchus kisutch) born in the upper tributary reaches often rear in natal streams before migrating to sea. However, those born in the lower reaches often encounter unsuitable habitat and emigrate during their first spring to seek non-natal rearing habitats. It is assumed that these early outmigrants are population losses. This study evaluated first-summer survival, and contribution to the adult population, of non-natal rearing juveniles in the Klamath River Basin. …

Zooplanktonic Community Dynamics Of The Minnesota River With An Ichthyoplankton Gear Comparison, Nathaniel Lederman

All Graduate Theses, Dissertations, and Other Capstone Projects

The Minnesota River, like many large rivers, has been functionally altered by human activities and climate change. The Minnesota Pollution Control Agency has designated 271 kilometers (50.3%) of the 539 kilometer Minnesota River as “biologically impaired.” However, assessing biological communities in large rivers is often difficult and limited to examination of upper trophic levels (e.g., piscivorous fishes). Few studies examined zooplanktonic communities, largely due to difficulties associated with sampling. Because of the need to improve assessment strategies for biological impairments in the Minnesota River, the zooplanktonic community, including crustaceous zooplankton, rotifers, macroinvertebrates, and ichthyoplankton was evaluated within an impaired and …

Draft Genome Sequences For Seven Streptococcus Parauberis Isolates From Wild Fish In The Chesapeake Bay, Ashley Haines, Emily Nebergall, Elvira Besong, Kimaya Council, Onaysha Lambert, David Gauthier

Biological Sciences Faculty Publications

Streptococcus parauberis is a pathogen of cattle and fish, closely related Streptococcus uberis and Streptococcus iniae. We report the genomes of seven S. parauberis strains recovered from striped bass (Morone saxatilis) in the Chesapeake Bay. The availability of these genomes will allow comparative genomic analysis of Chesapeake Bay S. parauberis strains versus S. parauberis cultured from other animal hosts and geographic regions.

It identifies those species that are threatened with extinction at the global level and occur within the ECA region. This comprehensive assessment, which is the first of its kind in the ECA, aims to provide improved knowledge of species presence and extinction risk status for the purposes of guiding conservation actions and improved policies for these species …

An Investigation Of Juvenile Alewife (Alosa Pseudoharengus) Habitat Use And Growth Using Natural Markers, Gregory Norman Labonte Ms

All Student Scholarship

This research attempts to connect patterns in growth and migration of an anadromous species. The goal of this research was to understand habitat movements and growth of juvenile alewives (Alosa pseudoharengus) in the Penobscot Estuary and Bay through the use of otolith microchemistry, otolith growth increments, and a laboratory stable isotope turnover study. Understanding the connection between growth and movement of juvenile alewives may lead to more accurate and sophisticated conservation and restoration methods for anadromous species.

Two New Species Of Geosesarma De Man, 1892 (Crustacea: Brachyura: Sesarmidae) From Palawan, The Philippines, Hendrik Freitag, Marivene Manuel-Santos, Peter K.L Ng

Biology Faculty Publications

Two new and relatively large species of semi-terrestrial sesarmid crabs of the genus Geosesarma De Man, 1892, are described from Palawan Island, Philippines. They are distinguishable from congeners by the characteristic structure of their carapace, chelipeds, ambulatory legs and male first gonopods. Aspects of their ecology are briefly discussed

A Genetically Distinct Hybrid Zone Occurs For Two Globally Invasive Mosquito Fish Species With Striking Phenotypic Resemblance, Rebecca J. Wilk, Lisa Horth

Biological Sciences Faculty Publications

Hybrid zones allow for the investigation of incipient speciation and related evolutionary processes of selection, gene flow, and migration. Interspecific dynamics, like competition, can impact the size, shape, and directional movement of species in hybrid zones. Hybrid zones contribute to a paradox for the biological species concept because interbreeding between species occurs while parental forms remain distinct. A long‐standing zone of intergradation or introgression exists for eastern and western mosquito fish (Gambusia holbrooki and G. affinis) around Mobile Bay, AL. The region has been studied episodically, over decades, making it perfect for addressing temporal dynamics and for providing …

A Bomb Set To Drop: Parthenogenetic Marmorkrebs For Sale In Ireland, A European Location Without Non-Indigenous Crayfish, Zen Faulkes

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Ireland is one of the few locations in Europe where non-indigenous North American crayfish species have not been introduced, and is a refuge for endangered white-clawed crayfish, Austropotamobius pallipes (Lereboullet, 1858). The parthenogenetic crayfish species Marmorkrebs, Procambarus fallax f. virginalis (Hagen, 1870), is sold in the pet trade in Ireland within the recorded range of A. pallipes. Marmorkrebs risk being introduced into Irish waters, where they could threaten A. pallipes populations, particularly as a vector for crayfish plague.

Dietary Overlap Of Native White Bass And Introduced Yellow Bass In Barren River, Micaela L. Montgomery

Mahurin Honors College Capstone Experience/Thesis Projects

In the Barren River Lake of south central Kentucky, native white bass, Morone chrysops, has experienced a decline in population after the introduction of yellow bass, Morone mississippiensis. These species are competing for resources due to an overlapping diet, likely contributing to the decline of the white bass. To explore this hypothesis, I examined the stomach contents and otoliths of white and yellow bass caught during their spawning time in spring 2012. There were 40 yellow bass and 128 white bass collected in Barren River upstream of Barren River Lake. Analysis of stomach contents revealed that both white and …

WEST COAST ESTUARINE MANAGED FISHERY (AREA 2)

Harvest strategies for aquatic resources managed by the Western Australian Department of Fisheries (the Department) are formal documents prepared to support the decision-making processes required to ensure the management of these resources are consistent with the principles of Ecologically Sustainable Development (ESD). The objectives of ESD are reflected in the objects of the Fish Resources Management Act 1994 (FRMA), Section 3, and the draft Aquatic Resources Management Bill 2013 (ARMB), Clause 9, which will replace the FRMA once enacted.

The publication of these strategies is intended to make the decision-making considerations and processes …

Finding The Needle And The Haystack: New Insights Into Locating Bog Turtles (Glyptemys Muhlenbergii) And Their Habitat In The Southeastern United States, Theresa Sonja Margareta Stratmann

All Theses

Because rare and cryptic species can be difficult to locate, distribution maps for these species are often inaccurate or incomplete. Bog Turtles (Glyptemys muhlenbergii) are emblematic of this challenge. In fact, conducting surveys of known, historical, and potential Bog Turtle habitat is a specific need stated in the Bog Turtle Northern Population Recovery Plan and in most Comprehensive Wildlife Conservation Strategies of states within the southern range. Therefore we examined ways to better locate Bog Turtle habitat and Bog Turtles within that habitat. First we determined a detection probability for a standardized trapping method so we could effectively survey for …

Variability In Movement Patterns And Habitat Use Of Two Species Of Pelecaniformes, Caroline Poli

All Theses

Information regarding movement patterns of seabirds is useful for understanding prey abundance and distribution, predicting overlap between bird activity and anthropogenic stressors, and assessing the effectiveness of reserves at protecting nesting or foraging habitat(Cairns 1992, Weimerskirch 2007, Weimerskirch et al. 2010). I examined movement patterns of 40 brown pelicans (Pelecanus occidentalis) satellite tagged in December 2010 in South Carolina, USA, and tracked until July 2013. Birds exhibited individual variability in movement patterns and 25% of individuals remained near the breeding colony during nonbreeding. Birds captured in South Carolina that did migrate wintered as far south as Guatemala, prospected and used …

Relative Abundances Of The Recently Introduced Barnacles, Megabalanus Coccopoma And An Unidentified Species Of Megabalanus, In The Southeastern U.S., Jennifer L. Tyson

Honors College Theses

ABSTRACT

Megabalanus coccopoma is a prominent invasive species off the coast of Georgia. Recently, among collected samples thought to be M. coccopoma, several individuals of an unidentified species of barnacle were found. The species has been identified as a Megabalanus species, but is still unidentified to the species level. Species identification is difficult due to morphological variation, inconsistent taxonomic keys, and unknown origin. In this study I developed a method to accurately distinguish M. coccopoma from the unidentified Megabalanus sp. using sequence differences in the mitochondrial Cytochrome Oxidase I (COI) gene. This study will provide an accurate estimate of …
