Biological Survey Of Elizabethtown College, Caroline Fegley, Aprille Mohn 2019 Elizabethtown College

Biological Survey Of Elizabethtown College, Caroline Fegley, Aprille Mohn

Landmark Conference Summer Research Symposium

The campus of Elizabethtown College possesses various ecosystems that frequently are overlooked by the student body and community. These ecosystems include forests, meadows, wetlands, streams, and ponds and provide habitat for a variety of plants and animals. We are advocating for the college to recognize these campus areas as the “Natural Lands of Elizabethtown College.” The goal of our project was to determine what species inhabit these natural lands. Our primary taxonomic focus was on birds. We determined the absence and presence of bird species common to the eastern United States. About three times a week for three weeks in ...

Contributions Of Fire Refugia To Resilient Ponderosa Pine And Dry Mixed‐Conifer Forest Landscapes, Jonathan D. Coop, Timothy J. Delory, William M. Downing, Sandra L. Haire, Meg A. Krawchuk, Carol Miller, Marc-André Parisien, Ryan B. Walker

Biology Faculty Publications

Altered fire regimes can drive major and enduring compositional shifts or losses of forest ecosystems. In western North America, ponderosa pine and dry mixed‐conifer forest types appear increasingly vulnerable to uncharacteristically extensive, high‐severity wildfire. However, unburned or only lightly impacted forest stands that persist within burn mosaics—termed fire refugia—may serve as tree seed sources and promote landscape recovery. We sampled tree regeneration along gradients of fire refugia proximity and density at 686 sites within the perimeters of 12 large wildfires that occurred between 2000 and 2005 in the interior western United States. We used generalized linear ...


Contextual Fear Learning And Memory Differ Between Stress Coping Styles In Zebrafish, Matthew R. Baker, Ryan Y. Wong 2019 University of Nebraska at Omaha

Contextual Fear Learning And Memory Differ Between Stress Coping Styles In Zebrafish, Matthew R. Baker, Ryan Y. Wong

Biology Faculty Publications

Animals frequently overcome stressors and the ability to learn and recall these salient experiences is essential to an individual’s survival. As part of an animal’s stress coping style, behavioral and physiological responses to stressors are often consistent across contexts and time. However, we are only beginning to understand how cognitive traits can be biased by different coping styles. Here we investigate learning and memory differences in zebrafish (Danio rerio) displaying proactive and reactive stress coping styles. We assessed learning rate and memory duration using an associative fear conditioning paradigm that trained zebrafish to associate a context with exposure ...


A New Approach To The Potential Energy Of Solids, RADHIKA CHAUHAN, Sanjeev K. Verma, Anushri Gupta, Anita Kumari, B. D. Indu 2019 Indian Institute of Technology Roorkee

A New Approach To The Potential Energy Of Solids, Radhika Chauhan, Sanjeev K. Verma, Anushri Gupta, Anita Kumari, B. D. Indu

Karbala International Journal of Modern Science

A general theory is developed to investigate the expression for potential energy without using (i) empirical results and (ii) process of parameterizing. The simple approach of thermodynamics is adopted to obtain the expressions for the interaction energy of solids in terms of interatomic separation and crystal volume. The new findings have been applied to obtain the expressions for bulk modulus and pressure. The variation of the potential energy function, which provides a means to understand the stability of a crystal has been found in excellent agreements to the earlier results. The use of obtained harmonic and anharmonic force constants may ...

Oomycete Metabarcoding Reveals The Presence Of Lagenidium Spp. In Phytotelmata, Paula Leoro-Garzon, Andrew J. Gonedes, Isabel Olivera, Aurelien Tartar 2019 Nova Southeastern University

Oomycete Metabarcoding Reveals The Presence Of Lagenidium Spp. In Phytotelmata, Paula Leoro-Garzon, Andrew J. Gonedes, Isabel Olivera, Aurelien Tartar

Biology Faculty Articles

The oomycete genus Lagenidium, which includes the mosquito biocontrol agent L. giganteum, is composed of animal pathogens, yet is phylogenetically closely related to the well characterized plant pathogens Phytophthora and Pythium spp. These phylogenetic affinities were further supported by the identification of canonical oomycete effectors in the L. giganteum transcriptome, and suggested, mirroring the endophytic abilities demonstrated in entomopathogenic fungi, that L. giganteum may have similarly retained capacities to establish interactions with plant tissues. To test this hypothesis, culture-independent, metabarcoding analyses aimed at detecting L. giganteum in bromeliad phytotelmata (a proven mosquito breeding ground) microbiomes were performed. Two independent and ...


Our Impressive Immune System: More Than A Defense, Alan L. Gillen, Jason Conrad 2019 Liberty University

Our Impressive Immune System: More Than A Defense, Alan L. Gillen, Jason Conrad

Alan L. Gillen

Most likely the immune system was put into place in the original human body design. We know from Exodus 20:11 and other verses that God completed His work of creation in six days. Therefore, the human body and its functional parts, including the components of the immune system, must have been part of the original creation. God said that all He had made was very good (Genesis 1:31). Since there were no pathogens (germs), parasites, or diseases prior the Edenic Fall and subsequent Curse, the immune system may have functioned differently in that world unmarred by sin and ...

Thermal Quality Explains Shift In Habitat Association From Forest To Clearings For Terrestrial-Breeding Frogs Along An Elevation Gradient In Colombia, Zachary Lange 2019 John Carroll University

Thermal Quality Explains Shift In Habitat Association From Forest To Clearings For Terrestrial-Breeding Frogs Along An Elevation Gradient In Colombia, Zachary Lange

Masters Theses

Tropical ectotherms are considered particularly sensitive to changes in the thermal environment from climate change and habitat alteration. Understanding how such species’ thermal physiology relates to their habitat associations in thermally heterogeneous landscapes may help us predict responses and develop sound conservation strategies for the future. We conducted a mark-recapture study of three terrestrial breeding anuran species (Pristimantis medemi, P. savagei, P. frater) in adjacent forest and anthropogenic clearings at field sites spread across seven elevations (415-1350 m asl) in the Colombian Andes. We also performed thermal preference and critical thermal maximum assays in the lab to investigate the relationship ...

We synthesize observations from 1979 to 2016 of a contact zone involving two subspecies of pocket gophers (Thomomys bottae connectens and T. b. opulentus) and their respective chewing lice (Geomydoecus aurei and G. centralis) along the Rio Grande Valley in New Mexico, U.S.A., to test predictions about the dynamics of the zone. Historically, the natural flood cycle of the Rio Grande prevented contact between the two subspecies of pocket gophers. Flood control measures completed in the 1930s permitted contact, thus establishing the hybrid zone between the pocket gophers and the contact zone between their lice (without hybridization). Since ...

High-diversity mixtures of perennial tallgrass prairie vegetation could be useful biomass feed-stocks for marginal farmland in the Midwestern United States. These agroenergy crops can help meet cel-lulosic agrofuel targets while also enhancing other ecosystem services on the landscape. One proposedadvantage of high-diversity prairie biomass feedstocks is that they should become nutrient limited at aslower rate than monoculture feedstocks. In this study, we examine rates of soil nutrient depletion and thephysiology and performance of a focal species (switchgrass,Panicum virgatumL.) in four prairie agroen-ergy feedstocks with different species composition and diversity. The feedstocks in this study were a1-species switchgrass monoculture, a ...

Background

TLR9 agonists are being developed as immunotherapy against malignancies and infections. TLR9 is primarily expressed in B cells and plasmacytoid dendritic cells (pDCs). TLR9 signalling may be critically important for B cell activity in lymph nodes but little is known about the in vivo impact of TLR9 agonism on human lymph node B cells. As a pre-defined sub-study within our clinical trial investigating TLR9 agonist MGN1703 (lefitolimod) treatment in the context of developing HIV cure strategies (NCT02443935), we assessed TLR9 agonist-mediated effects in lymph nodes.

Methods

Participants received MGN1703 for 24 weeks concurrent with antiretroviral therapy. Seven participants completed ...


Tourism And African Elephant (Loxodonta Africana) Behavior In Zambezi National Park, Zimbabwe, Brigit Rooney 2019 Western Kentucky University

Tourism And African Elephant (Loxodonta Africana) Behavior In Zambezi National Park, Zimbabwe, Brigit Rooney

Masters Theses & Specialist Projects

As charismatic megafauna and a flagship species, African elephants (Loxodonta africana) are vital to the African tourist economy. Conversely, high levels of wildlife tourism can induce behavioral shifts that push desired animals into less frequented areas and disrupt natural behaviors. In order to examine this trade-off, tourism levels and African elephant behaviors were studied in Zambezi National Park (ZNP) near Victoria Falls, Zimbabwe. Over the course of 14 weeks, in-person observations and camera traps in ZNP were used to collect geographic, demographic, and behavioral data from elephant sightings. As a proxy for human presence, geo-locational data were collected for each ...


Documenting Marine Mammal Behavior And Evaluating The Benefits And Consequences Of Viewing Marine Mammals In Southcentral Alaska, Lauren E. McCaslin 2019 Western Kentucky University

Documenting Marine Mammal Behavior And Evaluating The Benefits And Consequences Of Viewing Marine Mammals In Southcentral Alaska, Lauren E. Mccaslin

Masters Theses & Specialist Projects

Marine mammals are in a precarious conservation position because of anthropogenic impacts and historic perceptions that they are a consumable commodity. In light of changing abiotic conditions, further evaluation is needed on the habitat use, behavior, and interactions among marine mammals. Conservation legislation has helped protect species, but the greatest ground swelling may be the advent of the commercial whale watching industry. The feeding grounds in Alaskan waters have made this area a prime tourism location, and these nutrient-rich waters have resulted in a confluence of marine mammal species, including the appealing and abundant humpback whale (Megaptera novaeangliae) that may ...


Effect Of Sleep Loss On Executive Function And Baseline Corticosterone Levels In An Arctic-Breeding Songbird, The Lapland Longspur (Calcarius Lapponicus), Brett Hodinka 2019 Western Kentucky University

Effect Of Sleep Loss On Executive Function And Baseline Corticosterone Levels In An Arctic-Breeding Songbird, The Lapland Longspur (Calcarius Lapponicus), Brett Hodinka

Masters Theses & Specialist Projects

Sleep is a fundamental and essential component of vertebrate life, although its exact function remains unknown. Animals that are deprived of sleep typically show reduced neurobiological performance, health, and in some cases, survival. However, a number of animals exhibit adaptations that permit them to carry out normal activities even when sleep is restricted or deprived. Lapland longspurs (Calcarius lapponicus), arctic-breeding passerine birds, exhibit around-the-clock activity during their short breeding season, with an inactive period of only 3–4 h/day (71°N). Whether these birds suffer behavioral and physiological costs associated with acute sleep loss (SL) is unknown. To assess ...

Elemental hyperaccumulation protects plants from many aboveground herbivores. Little is known about effects of hyperaccumulation on belowground herbivores or their ecological interactions. To examine effects of plant selenium (Se) hyperaccumulation on nematode root herbivory, we investigated spatial distribution and speciation of Se in hyperaccumulator roots using X-ray microprobe analysis, and effects of root Se concentration on root-associated nematode communities. Perennial hyperaccumulators Stanleya pinnata and Astragalus bisulcatus, collected from a natural seleniferous grassland contained 100–1500 mg Se kg−1 root dry weight (DW). Selenium was concentrated in the cortex and epidermis of hyperaccumulator roots, with lower levels in the stele ...
