Characterization Of Stream Quality Of Five Ouachita River Tributaries Utilizing Macrobenthic Species And Fish Populations, Hunter Jones, Brockton Brown
Characterization Of Stream Quality Of Five Ouachita River Tributaries Utilizing Macrobenthic Species And Fish Populations, Hunter Jones, Brockton Brown
Scholars Day Conference
The Ouachita River originates in west-central Arkansas and exits the state in south-central Arkansas near El Dorado. There are many tributaries that make up the Ouachita River through its Arkansas journey. Five of these tributaries are located in Clark County and were selected for this research. Basic in situ water quality parameters were measured and the riparian zone was characterized at each sample site. The five streams selected were Decieper/Little Deceiper Creek, Mill Creek, DeRoche Creek, Saline Bayou, and Tupelo Creek. Macrobenthic and fish surveys were conducted at two sites (upper and lower) on each creek except Saline Bayou and …

Title: The Effect of Ocean Plastic on Plankton and Marine Ecosystems Abstract: This presentation aims to raise awareness for the harm plastics in our oceans are causing analysis and visualization of scientific data. It is largely inspired by the fourteenth United Nations Sustainable Development Goal: Life Below Water. The datasets used primary fall into two categories: ocean plastic content statistics and plankton population demographics. The presentation will also explore plankton’s role as the base of many aquatic ecosystems and model the impact a population decline could have on these ecosystems. The effects ocean plastics can have on our modern society …
Assessing The Legacy Of Large Woody Debris As Coastal Protection In Bc And Washington, Jessica Wilson
Assessing The Legacy Of Large Woody Debris As Coastal Protection In Bc And Washington, Jessica Wilson
Salish Sea Ecosystem Conference
Large Woody Debris (LWD) accumulates naturally in the coastal environment (Brennan et al., 2009; Sass, 2009) and is thought to be a vital component of a diverse coastal habitat ( Rich et al., 2014). Decreasing natural coverage of LWD (Heathfield & Walker, 2011) and increasing demand for environmentally sensitive coastal protection techniques has led to the promotion of LWD as a viable nature-based method of shoreline protection (e.g. Johannessen et al., 2014; Stewardship Centre for BC, 2016; Washington Department of Fish and Wildlife, 2016). However, there is currently no peer-reviewed literature assessing the efficacy of coastal protection using LWD. This …

Northern Kelp Crab (Pugettia Producta) Feeding Preferences - Kelp Crabs Eat Kelp, And Lots Else?, Katie Dobkowski
Salish Sea Ecosystem Conference
Bull kelp (Nereocystis luetkeana) is an important source of both habitat and primary production in the Salish Sea and appears to be in decline in certain areas. Northern Kelp Crabs (Pugettia producta) are large crustacean consumers that preferentially consume N. luetkeana over other local seaweed species in laboratory feeding trials and exert some level of top-down control on kelp populations in the field. We have observed differences in kelp crab density around the Salish Sea and noted P. producta living on invasive wireweed (Sargassum muticum) as well as on kelp and in other habitats. We used a combination of laboratory …

Puget Sound environmental recovery is a complex, wicked problem, including both ecosystem and human and cultural wellbeing. The Puget Sound Partnership (Partnership) is a small Washington State agency that serves as a backbone organization guiding Puget Sound recovery, coordinating and collaborating with hundreds of partner organizations to accelerate recovery of Puget Sound. Our partner organizations include state and federal agencies, tribes, cities, counties, non-profits, academic institutions, special purpose districts, and many others. In 2018, the Partnership began a journey to better enable and foster diversity, equity, inclusion, and justice within the agency itself, as well as within the Puget Sound …

Begin At The Beginning: Steps, Stumbles And Learnings On The Path To Understanding And Implementing Dei Practices In Regional Engo., Christianne Wilhelmson
Salish Sea Ecosystem Conference
In 2018, Georgia Strait Alliance made the decision to begin the journey of addressing the complex issue of diversity, equity and inclusion (DEI) in our organization, one that like many environmental groups in BC lacks diversity in its staff and board. We prioritized this as we recognized there is an inherent risk that our work and our organization could become irrelevant if we don’t represent the communities we claim to serve. In addition to diversity, we also needed to address the need to deepen our relationships with indigenous communities in the Georgia Strait region and reflect those relationships in our …
Analyzing The Flight Patterns And Behavior Of Dragonflies Engaged In Aerial Territory Battles, Brandon Hastings, Brandon Jackson
Analyzing The Flight Patterns And Behavior Of Dragonflies Engaged In Aerial Territory Battles, Brandon Hastings, Brandon Jackson
2020 Virtual Spring Student Showcase for Research and Creative Inquiry
It has previously been determined that male dragonflies occupying the most suitable territory within a habitat have a higher flight-muscle ratio (FMR) than those occupying poor territories, but it is unknown how this increased FMR relates to their flight patterns. This study examined the flight patterns of dragonflies engaged in aerial territory battles to investigate differences in maneuverability between winners and losers. 3D video data of dragonflies interacting in a natural habitat was analyzed for territorial flights. Winners showed a lower maximum angular velocity compared to losers.

Schistosomiasis is a leading parasitic infection that debilitates many individuals in sub Saharan Africa. Because this parasitic infection involves a snail as an intermediate host, we use a native prawn species as a natural predator to decrease the population of this snail community. This study focuses on Tomefa, a primarily fishing peri-urban community located oi the outskirts of Accra, the capital city of Ghana. A survey was also given to the local community measuring economic characteristics. In the laboratory, Macrobrachium spp prawn exhibit preference of Bulinus snails over Biomphalaria snails while non-parasitic snails were consumed in higher proportion to parasitized …

170— A Comparison Of Native And Invasive Plant Species Microhabitats In Western Ny, Emelyn Bell
GREAT Day Posters
Previous research concluded that the extended leaf phenology of invasive plant species Lonicera maackii (Amur Honeysuckle) reduced seed predation, possibly due to less favorable microclimates for invertebrate seed predators. In the fall of 2019, we conducted a field experiment to observe the microhabitat preferences of snails. In our study, we selected six pairs of invasive L. maackii and native Cornus racemosa (Gray Dogwood) throughout the Roemer Arboretum. Twice weekly, we recorded temperature, relative humidity, air velocity, light, soil pH, and soil moisture along with the number and size of snails found on the plant and within 0.3m of its surrounding …

260— Patterns Of Occupancy Of Artificial Nest Sites By Native Bees, Allison Menendez
GREAT Day Posters
Although people tend to think of honeybees when they think about pollination, many species of native bees are actually important pollinators. Declining native bee populations can be supported in several ways, including reducing pesticide use, providing native flowers as a food source, leaving natural nest sites unaltered, or even by providing artificial nests. At SUNY Geneseo, a bee barn with eleven wooden boxes filled with natural reed cavities of varying sizes is in the Spencer J Roemer Arboretum. Female bees lay brood in these cavities, and provision food for the developing young. Some native bees are overwintering in these cavities. …

333— Effectiveness Of Batesian Mimicry In The Ant Mimicking Spider Myrmarachne Formicaria, Alanna Richman, Bea Dipzinski
GREAT Day Posters
Myrmarachne formicaria is a non-native ant-mimicking spider that was first recorded in New York in 2006. Little is known about its natural history in its native range in Europe and Asia or in its newly colonized range in North America. Some spider species are Batesian mimics that resemble ants in order to avoid being eaten, since many potential predators will not prey on ants. To assess the effectiveness of Batesian mimicry in this species, we staged encounters with a larger salticid spider species that could be a potential predator of M. formicaria. In total, 12 predator spiders were observed …

136— Predation On Microbivalves By Juvenile Naticid Gastropods On San Salvador Island, The Bahamas, Eliza Merges
GREAT Day Posters
Predator-prey interactions, where snails eat clams, evolutionarily has been a key interaction within marine molluscan communities. There is evidence of molluscan extinctions in the fossil record that are marked by changes in predation ratios. In this study, we will investigate predation of microbivalves by juvenile naticid gastropods in a shallow marine setting on San Salvador Island in the Bahamas. We propose to test predation density within different environments (facies) of a lagoonal setting. Significantly different ratios between these facies in one time period can indicate that predator-prey interactions can change over time from one environment to another. It is more …

135— Coral-Sponge Interactions On Rocky Point Reef, San Salvador, Bahamas, Michael Harvey, Anna Meichenbaum, Brooke Stickles
GREAT Day Posters
We surveyed the intensity of competition for reef space between sponges and corals at the Rocky Point patch reef adjacent to San Salvador Island, The Bahamas. Our working hypothesis was that, because of a dearth of predators, fast growing, chemically unprotected sponges more likely to be involved in competitive interactions. Results indicate that competition for reef space was widespread, but contrary to our hypothesis no sponge or coral species was disproportionately more involved in these interactions. These results contradict previous studies on Rocky Point reef and in our discussion we propose an explanation for this discrepancy.

Reconstructing A Century Of Coastal Productivity And Predator Trophic Position In The Salish Sea Using Archival Harbor Seal Bone., Megan Feddern
Salish Sea Ecosystem Conference
Following the passage of the Marine Mammal Protection Act of 1972, pinniped populations along the west coast of North America experienced exponential population increases following historic lows in the 1970's. In the Salish Sea, this increase in pinniped abundance also corresponded to large scale changes environmental condition (ie. Pacific Decadal Oscillation; PDO) and declines of prey species (forage fish, salmon), creating new challenges and tradeoffs for fisheries management in the region. The objective of this research is to understand how an abundant top predator, harbor seals, respond to bottom up forces in the system such as shifts in primary productivity …

Shifting Phenology Of An Apex/Specialist Predator Tracks Changes In Its Favored Prey, Ailene Ettinger
Salish Sea Ecosystem Conference
Phenology, or the timing of biological activities such as migration, growth, and reproduction, can have dramatic implications for fitness; consumer phenology that is out of step with its resource phenology can cause increased mortality or reduced reproductive success. The timing of southern resident killer whale (SRKW, Orcinus orca) movements in the Salish Sea is thought to be related to seasonal migrations of their prey. In recent decades, the abundance and phenology of the favored prey of SRKWs, salmon, has shifted in many locations across the western United States. Here, we use the OrcaMaster Database to quantify seasonal variation in SRKW …
Sources, Sinks, Dispersion And Cycling Of Dissolved Polybrominated Diphenyl Ethers (Pbdes) Discharged In The Strait Of Georgia, Yuanji Sun
Salish Sea Ecosystem Conference
The temporal and spatial distribution of dissolved PBDE concentration in the Strait of Georgia (SoG) is combined with concentrations predicted from a time-dependent box model of the Salish Sea to investigate the sources, sinks, dispersion and cycling of PBDE congeners. Prominent sub-surface concentration maxima (up to ca. 400 pg/L for total PBDE) occasionally measured in the southern SoG point to the Iona Island Waste Water Treatment Plant diffusers, discharging primary-treated effluent at 72 - 106 m depth, as an important proximal point source of dissolved PBDE. The decreasing depth of concentration maximum with increasing congener bromination suggests that dissolved PBDEs …
