281— Insect Soundscapes In Western New York, 2021 SUNY Geneseo
281— Insect Soundscapes In Western New York, Sarah Metz, Mackenzie Bancroft, Dana Moukaled
Recent assessments of insect populations suggest significant declines in abundance and diversity across the globe. These assessments have not included western New York, so it is important to gain an understanding of the insect diversity and abundance in our local habitats, particularly grasslands. One noninvasive way to sample insect populations is to record the acoustic signals used by these animals. Male insects of several taxa advertise for mates in the late summer by producing species-specific vocalizations at potential breeding sites. We are using acoustic recordings to examine three local sites for their use by singing insects. Acoustic recordings collected during ...
Decline In Amphibian Health In Local Stream, 2021 Pepperdine University
Decline In Amphibian Health In Local Stream, Elyse Vetter, Elise Dearment, Colton Russell, Audrey Fontes, Lee Kats
Seaver College Research And Scholarly Achievement Symposium
Many local streams of the Santa Monica Mountains are populated by the native California Newt, Taricha torosa, a species of special concern. Arroyo Sequit is one of these streams, the upper and lower portions of which are split by a culvert and the Mulholland Highway. This stream and the surrounding areas burned during the Woolsey fire of 2018. Since the fire, construction has been ongoing in and around the stream. Two years post-fire (during the summer of 2020) significantly more newts were found in the stream than years prior. A large proportion of these newts were unhealthy in appearance, presenting ...

Making Environmental Education Accessible For All Students: Inclusion Of Students With Emotional And Behavioral Disabilities, Juliann Dupuis, Dawn Jacobs
Journal of Science Education for Students with Disabilities
One of the most difficult tasks of an educator is engaging students in rigorous learning opportunities. A greater challenge is finding ways in which environmental education can be accessible to all students, especially those with emotional and behavioral disabilities. This article and lesson provides best practices for engaging students with high incidence disabilities in environmental concepts through varied representations and expressions of content. In addition, teaching collaborative protocols to fully engage students with social skills challenges within the local environment are discussed. The instructional approaches are aligned to increasing academic discourse, building positive peer-peer relationships, and observation using multiple modalities.
Conspecific Aggression Of Invasive Crayfish, P. Clarkii, In Response To Chemical Cues, 2021 Department of Ecology and Evolutionary Biology, UCLA
Conspecific Aggression Of Invasive Crayfish, P. Clarkii, In Response To Chemical Cues, Elyse Vetter, Elise Dearment, Audrey Fontes, Gary Bucciarelli, Lee Kats
Seaver College Research And Scholarly Achievement Symposium
Red Swamp Crayfish, Procambarus clarkii, have caused vast damage to the stream ecosystem of the Santa Monica Mountains, following their invasive introduction. Through their extensive eating habits, high levels of aggression, and responsiveness to environmental stimuli, P. clarkii have a tremendous impact on the success of native species in the Santa Monica Mountains. With exposure to chemical cues, crayfish are able to perceive threats and react accordingly. To determine the extent of such chemoreception, pairs of P. clarkii were tested in the laboratory for conspecific aggression in the presence of native newt, native frog, and conspecific alarm cues. The level ...
The Effects Of Symbiote Ostracods On Invasive Crayfish Behavior, 2021 Department of Ecology and Evolutionary Biology, UCLA
The Effects Of Symbiote Ostracods On Invasive Crayfish Behavior, Audrey Fontes, Elyse Vetter, Gary Bucciarelli, Lee Kats
Seaver College Research And Scholarly Achievement Symposium
Invasive crayfish, Procambarus clarkii, are known to negatively impact the biodiversity of Santa Monica Mountain streams. Small symbiotes, ostracods, live on Procambarus clarkii in some local streams. However, their effect on the behaviour of invasive crayfish is unknown. We used an aqueous chlorobutanol solution to remove ostracods from crayfish. We paired control crayfish with those that had ostracods removed and scored aggressive interactions. Crayfish without ostracods were found to be significantly more aggressive towards crayfish with ostracods. When we compared feeding behavior, we found that crayfish without ostracods consumed food more quickly than control crayfish. We again subjected crayfish to ...

Journal of Bioresource Management
The main aim of our work was to investigate the breeding parameters in three orchard types in Algeria (apple, cherry and nectarine) for better conservation of existing species. A total of 149 active Turtle dove nests were monitored in these man–made agro-systems. Egg laying occurred from early May and continued until mid-August. Egg laying started later in cherry trees and stopped earlier in nectarines. Nest density was higher in apple orchards. Nests were located higher in nectarine. Clutch size was similar among orchard types. Northeast was the dominant orientation in all orchards. Breeding success was higher than that recorded ...

Journal of Bioresource Management
The buffer zones of Nigerian protected areas are poorly managed. Patas monkey (Erythrocebus patas) was studied in fact owing to its dearth of information on its ecology and existence in South-West Nigeria National Park. Therefore, it was necessary to examine E. patas spatial distribution and population structure in the Old Oyo National Park buffer zone ranges, situated in South-West Nigeria and as well know its dietary uptake alongside delineating its various activities. Observations were positioned on direct census methods. A total of 60 individuals of E. patas (23 female, 21 male, and 16 young individuals) were sighted within the study ...
Density Dependent Growth Of Pseudomonas Fluorescens In The Presence And Absence Of C. Elegans Predation In Liquid Media, 2021 University of Mississippi
Density Dependent Growth Of Pseudomonas Fluorescens In The Presence And Absence Of C. Elegans Predation In Liquid Media, Jack Landmann
The purpose of this study was to understand the predator-prey relationship between C. elegans worms and P. fluorescens bacteria in liquid media. We were aiming to create a predation model of the relationship between these two species.
This study was performed through three experiments. Using 96-well plates, we were able to measure the change in optical density (OD) of these wells and calculate the growth rate. This growth rate was then graphed and analyzed. The first experiment contained P. fluorescens and KB liquid media, this study demonstrated that the bacterial population has a carrying capacity. We were also able to ...
Population And Evolution Dynamics In Predator-Prey Systems With Anti-Predation Responses, 2021 The University of Western Ontario
Population And Evolution Dynamics In Predator-Prey Systems With Anti-Predation Responses, Yang Wang
Electronic Thesis and Dissertation Repository
This thesis studies the impact of anti-predation strategy on the population dynamics of predator-prey interactions. This work includes three research projects.
In the first project, we study a system of delay differential equations by considering both benefit and cost of anti-predation response, as well as a time delay in the transfer of biomass from the prey to the predator after predation. We reveal some insights on how the anti-predation response level and the biomass transfer delay jointly affect the population dynamics; we also show how the nonlinearity in the predation term mediated by the fear effect affects the long term ...
The Effect Of Changing Substrate On Arctic Aquatic Invertebrates Abundance, 2021 University of Maine at Farmington
The Effect Of Changing Substrate On Arctic Aquatic Invertebrates Abundance, Tom Dolman
Michael D. Wilson Symposium
Climate change is directly affecting tundra ecosystems in northern regions, and warming temperatures have caused discontinuous permafrost and thawing sediments across the region. This project investigates how increasing erosion and the foraging patterns of migratory snow geese may degrade habitat for aquatic invertebrates in the upper Mast River, located in Wapusk National Park, Manitoba, Canada. In the past two decades, many of the important species of aquatic invertebrates have shown declines. Declining invertebrate populations are predicted to affect aquatic ecosystems and decrease the resources available to shorebirds and waterfowl, which breed and migrate through this area.

Bulletin of Chinese Academy of Sciences (Chinese Version)
The Luancheng Agro-Ecosystem Experimental Station, the Chinese Academy of Sciences, is located in the piedmont plain area of North China Plain and the middle section of the Taihang Mountain alluvial plain. It is a typical representative of the high-yield agricultural eco-system in the groundwater irrigation area. Due to the large-scale and high-intensity agricultural production in recent decades, the regional groundwater has been seriously over exploited, and the risk of groundwater pollution has increased. However, the surface agro-ecosystem and aquifer are separated by thick vadose zones, hence the mechanism of the impact of surface agricultural activities on the quantity and quality ...

Impact Analysis On The Invasive Oriental Weather Loach (Misgurnus Anguillicaudatus) In The Grant Creek And Prairie Creek Watersheds At Midewin National Tallgrass Prairie, Adam Vanhaitsma
Scholar Week 2016 - present
Presentation Location: Weber Center, Room 101
In 2014, the invasive Oriental weather loach was found in the Prairie Creek wetland at Midewin National Tallgrass Prairie. While little is known about the Oriental weather loach and its impact on freshwater ecosystems it has become a widespread invasive species. Being the first to investigate the impact of the Oriental weather loach on the Grant Creek and Prairie Creek watersheds at Midewin National Tallgrass Prairie, we set traps for specimens from early June till late July in both watersheds. Each loach that was caught was euthanized and dissected in order to understand ...
Zebrafish (Danio Rerio) Hoxb6: An Exploration Into The Divergence Of Genomic Dna Sequence And Gene Expression Across Teleost Fishes Post-Genome Duplication, Amber Lynn Rittgers, Pierre Le Pabic, Adam Davis
Georgia Journal of Science
Hoxb6 is an evolutionarily conserved developmental regulatory gene that functions, in part, to pattern several organs and organ systems within the embryonic trunk during vertebrate embryogenesis. The cis-regulatory circuitry mediating trunk expression in mouse (Mus musculus) may be conserved across gnathostome vertebrates, as several other species show similar trunk expression patterns, including chicken (Gallus gallus), dogfish shark (Scyliorhinus canicula), and several teleost fishes. A whole genome duplication event that occurred in the lineage leading to teleost fishes has generated at least two Hoxb6 genes, hoxb6a and b6b. Two teleost fishes of the superorder Acanthopterygii, Japanese medaka (Oryzias latipes) and ...

Microplastics: Nacogdoches County’S Hidden Threat, 2021 Stephen F Austin State University
Microplastics: Nacogdoches County’S Hidden Threat, Jordan Stanford, Sydney Matlock, Courtney Sims, Samantha Montes
Undergraduate Research Conference
Microplastics and their threat to marine environments are well known, but studies in freshwater environments are few and far between. Microplastics can be created by the breaking down of plastics or in the process of making plastics. They affect biological lifeforms in a multitude of ways, water temperature, permeability of the sediment. Pollution in Texas waterways have motivated groups like the Environmental Protection Agency, Trash Free Texas, and Environment Texas to get involved. The objectives of this study are two analyze Bonita and La Nana Bayou for microplastic presence and to educate and create awareness for Nacogdoches County on microplastics ...

Montserrat Annual Writing Prize
This article uses a mythical creature, the phoenix, to examine and illustrate the biological principles for generation of an adult body plan from a single cell. Using the study of developmental biology, it explores the cellular and molecular biology that underpins the massive complexity of creating an adult body plan. It also explores the similarities and differences between different embryos, and how nature and evolution have shaped the biology of those embryos to create different body plans.
Correlation Between Abundance Of Fossils In Harvester Ant Nest And Proximity Of Fossil Sites, 2021 Southern Adventist University
Correlation Between Abundance Of Fossils In Harvester Ant Nest And Proximity Of Fossil Sites, Hayeong Woo
Campus Research Day
Harvester ants have an interesting behavior of bone collecting. Therefore, harvester ant nests that are positioned around the fossil sites contain various fossil fragments. If there is a statistically significant correlation between the abundance of fossil fragments and the distance of the ant nests from the main fossil sites, ant nests can potentially be used to predict the proximity of the main fossil sites.
Using Enclosed Y-Mazes To Assess Chemosensory Behavior In Reptiles, 2021 James Madison University

USDA National Wildlife Research Center - Staff Publications
Reptiles utilize a variety of environmental cues to inform and drive animal behavior such as chemical scent trails produced by food or conspecifics. Decrypting the scent-trailing behavior of vertebrates, particularly invasive species, enables the discovery of cues that induce exploratory behavior and can aid in the development of valuable basic and applied biological tools. However, pinpointing behaviors dominantly driven by chemical cues versus other competing environmental cues can be challenging. Y-mazes are common tools used in animal behavior research that allow quantification of vertebrate chemosensory behavior across a range of taxa. By reducing external stimuli, Y-mazes remove confounding factors and ...
Kleptoparasitic Hawk-Dove Games, 2021 Virginia Commonwealth University
Kleptoparasitic Hawk-Dove Games, Isabella H. Evans-Riester, Chasity T. Kay, Karina L. Ortiz-Suarez, Jan Rychtář, Dewey Taylor
Spora: A Journal of Biomathematics
The Hawk-Dove game is a classical game-theoretical model of potentially aggressive animal conflicts. In this paper, we apply game theory to a population of foraging animals that may engage in stealing food from one another. We assume that the population is composed of two types of individuals, Hawks and Doves. Hawks try to escalate encounters into aggressive contests while Doves engage in non-aggressive displays between themselves or concede to aggressive Hawks. The fitness of each type depends upon various natural parameters, such as food density, the mean handling time of a food item, as well as the mean times of ...
Adaptive Plasticity Of Coloration In Response To Environmental Change, 2021 Murray State University
Adaptive Plasticity Of Coloration In Response To Environmental Change, Karissa Coffield
When rapid environmental changes occur, different selective forces can create phenotypic trade-offs in which a trait can provide fitness benefits or costs under different environmental conditions. Amphibians are particularly vulnerable to environmental change, and previous research has revealed that some species will plastically respond to variation in temperature and ultra-violet radiation (UVR) by altering their coloration. Divergent selection on coloration may change with elevation and climate induced shifts in temperature because high temperatures are likely to result in lighter color morphs but as elevation increases, UVR exposure increases leading to the prediction that darker color morphs will be more common ...
