Animal Conservation In St. Louis, Kate O'Sullivan

Undergraduate Research Symposium

St. Louis has a multitude of organizations involved in the natural sciences. But how many of them actually contribute towards animal conservation? The St. Louis Zoo is an organization that focuses a lot of its effort on presentation, so how does that impact the funds that go towards actually saving the animals? I plan to dive into the different animal-based organizations in St. Louis and its surrounding areas, as well as discuss the positives and negatives of each organization. Furthermore, I will provide examples from several sources that I have been reviewing all year to support my claims. I plan …

Complex Dynamics Of Coral Gene Expression Responses To Low Ph Across Species, Veronica Z. Radice, Ana Martinez, Adina Paytan, Donald C. Potts, Daniel J. Barshis

Biological Sciences Faculty Publications

Coral capacity to tolerate low pH affects coral community composition and, ultimately, reef ecosystem function. Low pH submarine discharges (‘Ojo’; Yucatán, México) represent a natural laboratory to study plasticity and acclimatization to low pH in relation to ocean acidification. A previous >2‐year coral transplant experiment to ambient and low pH common garden sites revealed differential survivorship across species and sites, providing a framework to compare mechanistic responses to differential pH exposures. Here, we examined gene expression responses of transplants of three species of reef‐building corals (Porites astreoides, Porites porites and Siderastrea siderea) and their algal endosymbiont communities …

Economic Valuation Model Of Vanname Shrimp Culture And Mangrove Rehabilitation, Elrin Meivian Mongi Mongi, Mahawan Karuniasa, Mufti Petala Patria

Journal of Environmental Science and Sustainable Development

The current climate change is caused by anthropogenic activities involving energy and industry usage that affect the temperature and climate of the Earth. The Paris Agreement on climate change is a commitment by some countries to act to address climate change by developing sustainably and emitting low levels of carbon dioxide (CO2). Changes in the oceans include temperature increases, acidification, and changes in currents, leading to decreased productivity in fishing and aquaculture. Integrated mangrove shrimp farming, known as silvofisheries, has been recognized as environmentally friendly cultivation. The implementation of silvofishery is a form of mangrove ecosystem management that integrates ecology …

Community Structure Of Sea Urchin As An Indicator Of The Ecological Balance Of Coastal Areas, Abdul Wahab Radjab, Intan Rabiyanti, Fiqih Muharby

Journal of Environmental Science and Sustainable Development

Journal of Bioresource Management

Freshwater ichthyofauna is facing intensive stress as a result of urbanization and growing industries in Pakistan. The alien fish species are considered one of the major challenges due to their deleterious effects. Feeding habit analysis is a basic tool to evaluate the ecological stress on fish species residing in different habitats. The present study was designed to disclose the feeding overlap between Cyprinus carpio (Common Carp) and Hypophthalmichthys molitrix (Silver Carp) from Head Marala (river Chenab) and Mangla Dam (river Jhelum). For this purpose, 20 samples i-e 10 from each site of each fish species out of total 40 were …

Living Among Wildlife: Elevating Human-Wildlife Interactions And Coexistence, Bridget Rebecca Murphy

Graduate Student Portfolios, Professional Papers, and Capstone Projects

After a semester of learning, both in class and in nature, my writing honed in further on this human-nature divide. To me, I see humans as part of nature – as we are mammals, animals, part of the food chain, biological beings no higher than others on our planet. We have simply constructed this false narrative around us within our societies, minds and media that embeds this division between us and nature, between us and wildlife. Humans have been managing, stewarding, living off and within landscapes for thousands of years. As time and technology evolved, a lot of people began …

A Year Of Wins For Farmed Animals, Lewis Bollard

General – Farm Animal Issues

Although the European Union shelved its ambitious farmed animal welfare reforms, there were other “wins” for farmed animals in 2023. There were 130 new corporate pledges to eliminate cages for laying hens and the worst abuses of broiler chickens. So far, over 1,000 corporate pledges have been fully implemented, and 39% of American hens, 60% of European hens, and 80% of British hens are cage-free, up from 6%, 41%, and 48%, respectively, a decade ago. The US Supreme Court upheld California’s Proposition 12, which bans the sale of eggs, pork, and veal from caged animals and their offspring in California. …

Status Survey Of Eight Rare Aquatic Macroinvertebrates In East Texas, Alexandra Randall

Biology Theses

Freshwater is essential to human existence. The health of each freshwater source is connected to the survival of pollution intolerant species of aquatic macroinvertebrates in the orders Ephemeroptera, Plecoptera, and Trichoptera (EPT taxa). A higher presence of EPT taxa equates to better water quality because their water bound larvae assist in maintaining clean freshwater environments and will not survive in highly polluted water. Human disruption to natural environments is causing increases in polluted freshwater, leading to decreases in the presence of EPT taxa. Texas Parks and Wildlife Department documentation shows major concern for the populations of eight EPT species of …

Biophysical Factors Affecting Habitat Suitability For Crassostrea Virginica, Jason D. Tilley

Dissertations

Oyster reefs provide a variety of important ecosystem services. However, the mortality rate of eastern oyster, Crassostrea virginica, the dominant species that produces oyster reefs in the northern Gulf of Mexico, is increasing at an alarming rate due to a variety of abiotic and biological factors. I examined how biophysical factors, including the less-studied fatty acid profiles of the suspended particulate matter on which oysters feed, influenced morphometric condition of C. virginica.

I sampled suspended particulate matter (SPM) and oysters in-situ in the western Mississippi Sound, which historically supported the majority of oyster production in Mississippi waters. Sampling …

Dataset For The Incorporation Of Climate Change Into A Multiple Stressor Risk Assessment For The Chinook Salmon (Oncorhynchus Tshawytscha) Population In The Yakima River, Washington Usa, Wayne Landis, Chelsea J. Mitchell, John D. Hader, Rory Nathan, Emma E. Sharpe

Environmental Sciences Faculty and Staff Publications

Data files available below

This data set is in support of Landis et al (in press 2024). A key question in understanding the implications of climate change is how to integrate ecological risk assessments that focus on contaminants with the environmental alterations from climate projections. This article summarizes the results of integrating selected direct and indirect effects of climate change into an existing Bayesian network previously used for ecological risk assessment. The existing Bayesian network Relative Risk Model (BN-RRM) integrated the effects of organophosphate pesticides concentrations, water temperature, and dissolved oxygen levels on the Chinook salmon population in the Yakima …

The Influence Of Invasive Species On Fishers’ Satisfactions, Caroline M. Laplante

School of Natural Resources: Dissertations, Theses, and Student Research

Invasives species are prevalent and widespread in North America. Outdoor recreational activities, such as fishing, introduce a point in which humans may interact with invasive species and have to adapt their own behaviors. Bigheaded carp in the Missouri River below Gavin’s Point Dam are a group of invasive fish species that were thought to be negatively relating to recreational fishers’ satisfactions. Using a content analysis and an importance-grid, we conclude that invasive species do not strongly relate to recreational paddlefish fishers’ satisfactions. Paddlefish fishers represent a small sub-set of recreational fishers in Nebraska and South Dakota. The content analysis revealed …

Understanding Avidities Of Recreational Activities For People Possessing Fishing Licenses And Residing In Urban Environments, Kyle F. Hansen

School of Natural Resources: Dissertations, Theses, and Student Research

Recreational fishing is one of the world's most popular pastimes, wherein participation is associated with sociodemographic factors. Even so, fishing license sales are declining in the USA in conjunction with a reduction in rural populations as people move to urban areas. Thus, urban areas are constantly growing in population size, population diversity, and geographic size suggesting a need to understand fishing participation in these growing areas. Natural resource managers often use participation to understand recreationists, yet avidity could provide a new way to understand recreationists. The goal of our study is to understand what sociodemographic factors influence the fishing avidity …

The Sociocultural Significance Of Maine's Oyster Based On Media Coverage Analysis, Syeira Clark

Honors College

Throughout the last decade, the oyster aquaculture industry in Maine has boomed, with 6 million pounds of oysters being harvested in 2021, about the amount that was harvested in 2016 (Cough, 2022). According to the founders of the Maine Oyster Trail, there are over 150 oyster farms currently operating on Maine’s coast, which is about twice as many as there were in 2016 (Maine Sea Grant). With this boom in the industry has come a wave of opportunity, as well as news coverage about the shellfish. This study examines the socio-cultural significance to the state of Maine. While the oyster …

State Of The Fisheries: Status Reports And Aquatic Resources Of Western Australia 2022/23, S.J. Newman, K.G. Santoro, D.J. Gaughan

Status reports of the fisheries and aquatic resources

Aquatic resources within Western Australia (WA) are in good condition, and this has positioned WA as a global leader in sustainable fisheries management. The sustainable fisheries of WA continue to support our strong economy and regional communities. Nonetheless, the lack of a consistent approach to build in the knowledge of Traditional Owners remains a gap in our longer term fisheries science in Western Australia.

Climate change and climate variability continues to impact fish stocks, challenging our ability to effectively monitor, assess, and manage fish stocks. We are continually working with our stakeholders, and the broader community to be adaptive, responsive, …

Culled Lionfish Sexual Maturity Over A Four-Year Timespan​, Christina Bland, Jurgen Hauer, Bilal Saleem, Noelle James

Symposium of Student Scholars

Lionfish are invasive in the Atlantic and the Caribbean. Like many other invasive species, they do not have any natural predators in these areas, so their population can grow unchecked. This can decrease the population of native fish species due to lionfish eating to excess. Because of their impact on native species, resource managers have incentivized lionfish hunting. Hunters were paid $6 USD for every pound of lionfish they brought in, so they possibly favored larger lionfish to increase their reward which would lead to an adaptive advantage for fish of smaller sizes. We hypothesized that the lionfish bounty program …
