Seroton-Ing Down The Stress: Serotonergic Activity In Response To Predators In Threespined Stickleback (Gasterosteus Aculeatus), Michaela M. Rogers Apr 2023

Seroton-Ing Down The Stress: Serotonergic Activity In Response To Predators In Threespined Stickleback (Gasterosteus Aculeatus), Michaela M. Rogers

2023 Midwest Ecology & Evolution Conference

Animals constantly face stress in the environment due to rapid human-induced changes. A strong interest lies in the evolution of coping mechanisms that can help organisms deal with and respond to these stressors. Serotonin is a neurotransmitter that is highly conserved across taxonomic groups and is upregulated in response to a broad range of stressors, including predator exposure. Serotonin upregulation can help organisms cope with the threat of a predator by decreasing fear and anxiety. Previous studies have shown an increase in serotonergic activity following acute predator exposures in mice, rats, and fish after only one exposure, but less is …

Assessing The Health And Behavioral Effects Of Turtle Racing On Eastern Box Turtles (Terrapene Carolina), Michelle K. Weaver Apr 2023

Assessing The Health And Behavioral Effects Of Turtle Racing On Eastern Box Turtles (Terrapene Carolina), Michelle K. Weaver

2023 Midwest Ecology & Evolution Conference

Turtle racing involves the public capturing largely wild-caught box turtles (Terrapene spp.) and racing them at standalone events or at races incorporated into larger family events (e.g., festivals). These turtle races are legal in most states because of a lack of regulations and/or funding to enforce regulations that may exist. Moreover, we lack information on the potential effects (e.g., disease transmission, survival, movements, and general health) of races on the turtles that could help support the implementation of regulations. Our objective was to understand the short-term and long-term health and behavioral effects of turtle races on eastern box turtles (Terrapene …

Late Cretaceous Marine Vertebrates From The Tarrant Formation, Tarrant County, Texas U.S.A, Aaron Johnson, Kenshu Shimada Apr 2023

Late Cretaceous Marine Vertebrates From The Tarrant Formation, Tarrant County, Texas U.S.A, Aaron Johnson, Kenshu Shimada

2023 Midwest Ecology & Evolution Conference

The Tarrant Formation (middle Cenomanian: ca. 96 million years ago) is a stratigraphic member of the Upper Cretaceous Eagle Ford Group in Texas, U.S.A., and consists of calcareous sandstone formed near the East Texas Embayment of the Late Cretaceous Western Interior Seaway, an epicontinental seaway in North America. We examined vertebrate fossils from the Tarrant Formation based on specimens collected through surface collecting and bulk sampling from three localities in Tarrant County, Texas, including the type locality of a pachyrhizodontid fish, Polcynichthys lloydhilli. Our preliminary examination shows that the fossil fauna includes shark species such as Ptychodus anonymous, Archaeolamna sp., …

Habitiat Structure And Ecomorphology Of Fishes In Neotropical Blackwater Creeks., Devya Hemraj-Naraine Apr 2023

Habitiat Structure And Ecomorphology Of Fishes In Neotropical Blackwater Creeks., Devya Hemraj-Naraine

2023 Midwest Ecology & Evolution Conference

Freshwater ecosystems provide habitat for a diversity of aquatic flora and fauna. However, anthropogenic activities like mining and pollution alters aquatic habitats and the ecosystem services they provide. In South America, which hosts one quarter of all freshwater fish species, aquatic habitats are under considerable encroachment from human development. We surveyed nine blackwater creeks tributary to the Demarara River along a major Highway in Guyana to determine whether fish morphology and community structure correlate with habitat characteristics among sites with different degrees of human impact. Twenty-three morphological traits were measured on 3-5 adult specimens of each species. The most abundant …

Functional Implications Reflected In Neurocranial Morphology Of Lamniform Sharks (Elasmobranchii: Lamniformes), Jake J. Wood Apr 2023

Functional Implications Reflected In Neurocranial Morphology Of Lamniform Sharks (Elasmobranchii: Lamniformes), Jake J. Wood

2023 Midwest Ecology & Evolution Conference

Lamniform sharks (Elasmobranchii: Lamniformes) display diverse habitat preferences and lifestyles. Based on museum specimens and published illustrations, we examined the proportion of the anteroposterior length of the rostral, olfactory, optic, and otic regions with respect to the neurocranial length in each lamniform species as a proxy of relative importance of each sensory region (electroreception, olfaction, vision, and ‘coordination’) to its lifestyle. We show that: 1) Carcharias and Megachasma (ragged-tooth and megamouth) have short rostral and large otic regions indicative of slower-swimming pelagic lifestyles with elevated coordination for balancing in the water column; 2) Alopias pelagicus, A. vulpinus, …

Habitat Characteristics And Winter Use Of Woodpecker-Excavated Tree Cavities, Adrianna Yoder Apr 2023

Habitat Characteristics And Winter Use Of Woodpecker-Excavated Tree Cavities, Adrianna Yoder

2023 Midwest Ecology & Evolution Conference

Avifauna are in decline in North America, including red-headed woodpeckers (Melanerpes erythrocephalus). Red-headed woodpeckers are negatively impacted by urbanization, which has decreased their ideal habitats of oak-savannas and through the management of urban trees there has been a reduction in the amount of tree decay, a necessary feature of suitable trees that woodpeckers can make cavities in. Cavities are created and used as nests in the breeding season (spring/summer) and as roost-sites in the non-breeding season (fall/winter). In the Chicagoland region, during the fall some red-headed woodpeckers migrate while others do not and remain overwinter, making them facultative …

Repeatability And Distribution Of Behavior Types Over Time And Across Populations In Free-Ranging Adult And Juvenile Ornate Box Turtles (Terrapene Ornata), Abigail Trautman Apr 2023

Repeatability And Distribution Of Behavior Types Over Time And Across Populations In Free-Ranging Adult And Juvenile Ornate Box Turtles (Terrapene Ornata), Abigail Trautman

2023 Midwest Ecology & Evolution Conference

As studies continue to investigate inter-individual variation, it is becoming increasingly evident that individual animals have their own unique behavior type (personality; repeatable behaviors over time and context) that persists throughout their life. Behavior is simply different forms of motion, and a behavior type influences which motions (behaviors) are most likely to be on display. Behavioral types can influence resource acquisition, predation risk, and mating opportunities and thus can directly influence the fitness of any given individual. In this study, we examine the behavior types of free-ranging adult ornate box turtles (Terrapene ornata), including their repeatability and variation …

Relationship Between Learning And Bt In Ornate Box Turtles (Terrapene Ornata), Brianna M. Wilson Apr 2023

Relationship Between Learning And Bt In Ornate Box Turtles (Terrapene Ornata), Brianna M. Wilson

2023 Midwest Ecology & Evolution Conference

Cognition is important to the individual animal and can help determine its role and impact on its ecological niche. Variation in cognition may influence the way animals interact with their environment and their performance in certain behaviors such as resource acquisition, range philopatry, and navigation. The question has been raised as to whether cognitive styles such as fast-slow or speed-accuracy types share a relationship with behavioral type. Animal personality (behavioral type) is made up of five axes: boldness, aggression, sociality, activity, and exploration. In this study, we investigate learning in a western Nebraska population of ornate box turtles (Terrapene …

An Optimal Patch Use Model For Nitrogen Foraging In Arbuscular Mycorrhizal Fungi, Xin Lin Apr 2023

An Optimal Patch Use Model For Nitrogen Foraging In Arbuscular Mycorrhizal Fungi, Xin Lin

2023 Midwest Ecology & Evolution Conference

Optimal Foraging Theory has been widely used to study animal foraging behaviors, but has seldom been applied to symbiotic microbes like arbuscular mycorrhizal (AM) fungi. To date we know little about how AM fungi make decisions to forage in different nutrient patches. To help address this gap we here apply Optimal Foraging Theory to understand how AM fungi forage for nitrogen. We focus on nitrogen because AM fungi need more nitrogen than their plant hosts and soil nitrogen availability can shift the relationship between AM fungi and their hosts from mutualism to parasitism. We present a stochastic dynamic programming model …

Effect Of Temperature Variation On Endurance Swimming Capacity Of Juvenile White Sturgeon (Acipenser Transmontanus), Alex M. Stolberg Apr 2023

Effect Of Temperature Variation On Endurance Swimming Capacity Of Juvenile White Sturgeon (Acipenser Transmontanus), Alex M. Stolberg

2023 Midwest Ecology & Evolution Conference

White sturgeon (Acipenser transmontanus), a species within one of the most globally threatened taxa, are highly susceptible to changes in their environments due to unique life history traits. Specifically, juvenile white sturgeon are impacted by altered watershed dynamics caused by water diversion structures such as dams, weirs, irrigation ditches, or levees. One location of great concern is the Sacramento-San Joaquin (S-SJ) watershed where decades of water diversion has brought on changes to the temperature, flow, and management of the area. This study looks to primarily identify the impact of water temperature on the endurance swimming capacity of juvenile white sturgeon, …

Phosphours Trasnport In Soil: Locating And Identifying A Limiting Element, Jeremy Giannone Apr 2023

Phosphours Trasnport In Soil: Locating And Identifying A Limiting Element, Jeremy Giannone

2023 Midwest Ecology & Evolution Conference

The phosphorus (P) cycle is not well understood. While carbon (C) and nitrogen (N) have gas phases, P does not. Phosphorus runoff in waterways and its shortage are both understood since their causes are due to agricultural demands. Fertilizers increase the rate of phosphorus in the soil leading to greater runoff which then accumulates in the surrounding bodies of water.1 From an economic perspective the phosphorus availability and food prices have a direct correlation. The instability of phosphate prices may have direct causation to the instability of the food and agriculture markets.2In order to deal with these …

Rapid Assesment Of Aquatic Insect Diversity And Abundance Used To Evaluate The Quality Of Stream Restoration, Kaleb Stephen Kindoll Apr 2023

Rapid Assesment Of Aquatic Insect Diversity And Abundance Used To Evaluate The Quality Of Stream Restoration, Kaleb Stephen Kindoll

2023 Midwest Ecology & Evolution Conference

Stream and wetland restoration activities seek to improve the function of aquatic ecosystems. Measurement of the diversity and abundance of aquatic insects are commonly used to evaluate the success of restoration efforts, but these measurements are often very time consuming. In this study, we attempt to construct an efficient method that can be used to rapidly assess the diversity and abundance of aquatic insects as a measure of the quality of stream restoration. We suspended uniform sized pieces of cardboard paper coated with adhesive to trap insects in three different environments: one restored and two unrestored streams with similar characteristics. …

Identifying Olfactory Receptors In The Pole Borer, Neandra Brunnea (Coleoptera: Cerambycidae), Kayla M. Hefner Apr 2023

Identifying Olfactory Receptors In The Pole Borer, Neandra Brunnea (Coleoptera: Cerambycidae), Kayla M. Hefner

2023 Midwest Ecology & Evolution Conference

The behavior of longhorned beetles (Coleoptera: Cerambycidae) is strongly shaped by volatile compounds, which can dictate the selection of hosts and mates, segregate heterospecifics, and initiate oviposition. These compounds are primarily detected at the molecular level by the protein family of odorant receptors (ORs), which rapidly evolve in response to evolutionary changes such as diet or sociality. Thus, the OR gene family could provide great insight into the ecology and evolution of animals, especially when their chemical ecology is otherwise poorly understood. We are examining the ORs of the pole borer Neandra brunnea (Cerambycidae: Parandrinae), for which the specific role …

Historical Climate-Influenced Shifts In Flower Shape And Production Of A Common Annual Plant, Orange Jewelweed (Impatiens Capensis), Amber M. Stanley Apr 2023

Historical Climate-Influenced Shifts In Flower Shape And Production Of A Common Annual Plant, Orange Jewelweed (Impatiens Capensis), Amber M. Stanley

2023 Midwest Ecology & Evolution Conference

Climate change is a major human-mediated stressor that has been altering temperature patterns across the globe since the Industrial Revolution. In the Eastern United States, it has been projected that the average annual temperature will increase by 3-5 degrees Celsius by the year 2100. Such environmental changes have the potential to disrupt key interactions between species. For example, the vast majority (ca. 90%) of flowering plants rely on animal pollinators to transfer pollen between individuals to reproduce. Higher temperatures cause many plant species to flower up to 3-4 weeks earlier in the year, but pollinator activity has not shifted with …

Initial Steps In Testing The Stress Gradient Hypothesis For Selenium Exposure In Soil Bacteria, Kristian J. Harris Apr 2023

Initial Steps In Testing The Stress Gradient Hypothesis For Selenium Exposure In Soil Bacteria, Kristian J. Harris

2023 Midwest Ecology & Evolution Conference

The Stress Gradient Hypothesis (SGH) states that interspecific interactions should shift from competitive to facilitative interactions as environmental stress increases. Selenium (Se) is a naturally occurring metalloid that acts as an environmental pollutant and as an essential micronutrient. Due to its metallic properties, Se acts as an oxidative stress and can be toxic to plants and animals. Given this, Se in soil systems acts as an abiotic stress that influences species composition and species interactions. Within soils, bacteria and fungi have evolved to tolerate Se via detoxification and Se processing for respiration and studies show that metal detoxification traits like …

Using Podcasts To Bring National Estuarine Research Reserves Into The Classroom For Grades 6-12, Kaitlyn M. Dirr

Senior Theses

In a typical classroom setting, there are significant challenges to exposing students to concepts related to earth sciences and the environment. These challenges are exacerbated when conveying lessons about geographic areas with limited access, such as oceans and coastlines (Louv, 2010). It is now more important than ever for environmental education to improve and adapt to our changing world. Educators may have the opportunity to bring these subjects to life by using media content such as podcasts to introduce students to new places and the scientists, managers and educators that work in those spaces. In the United States, there exists …

Rhythms Of The Earth—Editorial Introduction, Karim-Aly S. Kassam, Morgan Ruelle, Christopher P. Dunn, Raj Pandya, Felice Wyndham Apr 2023

Rhythms Of The Earth—Editorial Introduction, Karim-Aly S. Kassam, Morgan Ruelle, Christopher P. Dunn, Raj Pandya, Felice Wyndham

Sustainability and Social Justice

This special issue of GeoHealth, entitled Rhythms of the Earth: Ecological Calendars and Anticipating the Anthropogenic Climate Crisis, is a transdisciplinary articulation of a methodology of hope to confront the multiple injustices of the Anthropocene. One of the greatest challenges of the climate crisis is the lack of predictability at the scale of communities where impacts are most immediate. Indigenous and rural societies face an ever shifting “new normal” through increasing inconsistency in the seasonality of temperature and precipitation, as well as greater frequency of extreme weather events. With global food systems dependent on local and small producers, climatic variability …

Individual-Level Responses To Rapid Climate Change In Common Terns (Sterna Hirundo) And Arctic Terns (Sterna Paradisaea), Kaiulani A. Sund Apr 2023

Individual-Level Responses To Rapid Climate Change In Common Terns (Sterna Hirundo) And Arctic Terns (Sterna Paradisaea), Kaiulani A. Sund

Student Publications

This study examines fine-scale environmental changes and intraspecific variation in the diet and foraging behavior of two seabirds in the Gulf of Maine, one of the fastest-warming regions of the ocean. This variation on the individual level, or behavioral plasticity, may help long-lived species to persist in rapidly changing environments. As the water warms, seabirds’ preferred prey (hake and herring) follow cooler waters deeper and farther offshore. It is unlikely that all individuals respond to changing food availability in the same way. For common terns (Sterna hirundo) and Arctic terns (Sterna paradisaea) breeding on Petit Manan …

Effects Of Habitat Management On Rodent Diversity, Abundance, And Virus Infection Dynamics, Nathaniel Mull, Amy Schexnayder, Abigail Stolt, Tarja Sironen, Kristian M. Forbes Apr 2023

Effects Of Habitat Management On Rodent Diversity, Abundance, And Virus Infection Dynamics, Nathaniel Mull, Amy Schexnayder, Abigail Stolt, Tarja Sironen, Kristian M. Forbes

Biological Sciences Faculty Publications and Presentations

As anthropogenic factors continue to degrade natural areas, habitat management is needed to restore and maintain biodiversity. However, the impacts of different habitat management regimes on ecosystems have largely focused on vegetation analyses, with limited evaluation of downstream effects on wildlife. We compared the effects of grassland management regimes (prescribed burning, cutting/haying, or no active management) on rodent communities and the viruses they hosted. Rodents were trapped in 13 existing grassland sites in Northwest Arkansas, USA during 2020 and 2021. Rodent blood samples were screened for antibodies against three common rodent-borne virus groups: orthohantaviruses, arenaviruses, and orthopoxviruses. We captured 616 …

A Survey Of Captive Wild And Exotic Animal Training Programs In The Eastern United States, Savannah Atchison Apr 2023

A Survey Of Captive Wild And Exotic Animal Training Programs In The Eastern United States, Savannah Atchison

Senior Honors Theses

Methods of positive reinforcement as a successful means for animal training are the result of many years of research into operant conditioning and learning. However, current literature is unclear on the extent to which these methods are utilized in captive wild and exotic animal populations in the United States. Through phone interviews with animal trainers employed at zoos and wildlife rehabilitation centers in the eastern United States, the author determined that these facilities are currently utilizing positive reinforcement training methods which are proving to be a great benefit for all parties involved. They are enabling a variety of voluntary health …

Alfred Russel Wallace Notes 25. Wallace And The 'Physical Environment'., Charles H. Smith Apr 2023

Alfred Russel Wallace Notes 25. Wallace And The 'Physical Environment'., Charles H. Smith

Faculty/Staff Personal Papers

Alfred Russel Wallace’s natural selection essay of 1858 has been held to frame a greater role for the physical environment in forcing selection regimes than we find in Darwin’s writings, but here that verdict is challenged by a re-examination of both the essay itself, and period usage of the term ‘physical.’

The Status Of Invasive Dusky Slug (Arion) Species In The Upper Great Lakes: A Molecular Approach, Olivia W. Hall Apr 2023

The Status Of Invasive Dusky Slug (Arion) Species In The Upper Great Lakes: A Molecular Approach, Olivia W. Hall

All NMU Master's Theses

I update the distribution of two cryptic slug species, Arion fuscus and Arion subfuscus, in the Upper Great Lakes of the United States using molecular identification methods. Arion fuscus has not previously been reported in the literature in this region, and Arion subfuscus has previously been reported as abundant. However, all previous distribution studies were determined using visual identification tools, which can result in misidentification between cryptic species. To molecularly re-examine these distribution maps, I used a mitochondrial ribosomal subunit 16S PCR amplification and subsequent SSpI and MfeI restriction enzyme digest to identify slug specimens. I collected slugs in …

Pathogen Risk Assessment On Arabian Felines In The United Arab Emirates, Laia Montserrat Stefano Apr 2023

Pathogen Risk Assessment On Arabian Felines In The United Arab Emirates, Laia Montserrat Stefano

Dissertations

The Arabian Peninsula has been known to harbour five species of felines, namely leopards (Panthera pardus), cheetahs (Acinonyx jubatus), caracals (Caracal caracal), sand cats (Felis margarita), and wildcats (Felis silvestris). Currently, their situation in the wild is critical in the region and ex situ breeding efforts are the greatest hope to restore their populations. However, these efforts need to go hand-in-hand with focus on their health, since pathogens are known to be a serious threat to animals under managed care. Globally, the potential pathogens of these five species include viruses, …

Tanzania Journal of Science

This study analyzed the land use and land cover (LULC) changes from 2000 to 2020 and examined its influence on wildlife distribution and abundance. LULC from satellite imagery for 2000, 2012 and 2020 were acquired from the United States Geological Survey (USGS). Supervised classification along with a maximum likelihood algorithm was used to classify satellite imagery into eight LULC classes: bareland, woodland, wetland, shrubland, grassland, waterbodies, cropland and built-up land. The results showed that grassland, wetland and woodland had declined, while shrubland, cropland and built-up land increased from 2000 to 2020. Grassland, wetland and woodland decreased from 48.1%, 14.1% and …

Heterospecific Anural Eavesdropping Cues, Lucia C. Maldonado, Hayley Lunn, Max Sprute, Andrew Wang, Ripley Conklin, Nolan Gentile, Conor Kramer, Lee Kats Mar 2023

Heterospecific Anural Eavesdropping Cues, Lucia C. Maldonado, Hayley Lunn, Max Sprute, Andrew Wang, Ripley Conklin, Nolan Gentile, Conor Kramer, Lee Kats

Seaver College Research And Scholarly Achievement Symposium

The ability to communicate within species is a trait utilized by every organism. Using cues conspecifically creates a better chance of survival for other members of the species and increases fitness overall. However, using cues heterospecifically also poses a great advantage as animals can eavesdrop on cues released by another species. Previous studies have recorded that eavesdropping is beneficial to prey species, such as squirrels reacting to bird calls and tadpoles reacting to visual and chemical cues to avoid predation. We asked how one local and one exotic species of frog would respond to cues emitted by another local species …
