Isolation Of Caldatribacterium (Op9) And Investigation Of Its Potential Interactions With A Novel, Co-Cultivated Thermodesulfobacterium Species, Toshio Alvarado 2019 California State University, San Bernardino

Isolation Of Caldatribacterium (Op9) And Investigation Of Its Potential Interactions With A Novel, Co-Cultivated Thermodesulfobacterium Species, Toshio Alvarado

Electronic Theses, Projects, and Dissertations

Atribacteria (OP9), candidate phylum with no representatives in pure culture, is found in various anaerobic environments worldwide. “Caldatribacterium”, a lineage within Atribacteria that is predicted to be a strictly anaerobic sugar fermenter based on cultivation-independent genomic analyses, is currently being maintained in lab enrichment cultures with fucose as its sole growth substrate. Metagenomics and 16S rRNA gene tag sequencing indicated that the fucose culture was a co-culture of “Caldatribacterium” and an uncultivated member of the genus Thermodesulfobacterium. Due to failed attempts to isolate “Caldatribacterium” by dilution-to-extinction and plating, it was hypothesized that “Caldatribacterium” is dependent in some way on the ...


Using Single-Cell Sorting, Fish And 13c-Labeling To Cultivate And Assess Carbon Substrate Utilization Of ‘Aigarchaeota’ And Other Novel Thermophiles, Damon Kurtis Mosier 2019 California State University, San Bernardino

Using Single-Cell Sorting, Fish And 13c-Labeling To Cultivate And Assess Carbon Substrate Utilization Of ‘Aigarchaeota’ And Other Novel Thermophiles, Damon Kurtis Mosier

Electronic Theses, Projects, and Dissertations

‘Aigarchaeota’, a deeply branching lineage in the domain Archaea with no cultivated representatives, includes both thermophilic and hyperthermophilic microorganisms that reside in terrestrial and marine geothermal environments. The ‘Aigarchaeota’ consists of at least nine proposed genus-level groups that have been confirmed via 16S rRNA sequencing, with ‘Aigarchaeota’ Group 1 (AigG1) being the focus of this study. Based on cultivation-independent genomic data available from several AigG1 members in Great Boiling Spring (GBS), NV, and Yellowstone National Park, 22 different types of growth media were designed and tested for their ability to support growth of AigG1. One of these cultures, G1-10, was ...


Deep Benthic Coral Habitats Of Glacier Bay National Park And Preserve, Alaska, Elise C. Hartill 2019 University of Maine

Deep Benthic Coral Habitats Of Glacier Bay National Park And Preserve, Alaska, Elise C. Hartill

Electronic Theses and Dissertations

Glacier Bay National Park and Preserve in Southeast Alaska is a system of fjords that presents an ideal natural laboratory to study terrestrial, aquatic and marine patterns of succession due to its unique and recent history of deglaciation. The patterns of deep benthic community assemblages in the fjords of Glacier Bay were investigated by quantitative assessment of underwater photo-quadrats collected using a remotely operated vehicle. The percent cover and diversity of species were lowest near the glaciated heads of the fjords and highest in the Central Channel and at the mouths of the fjords of Glacier Bay, where oceanographic conditions ...

The Value Of Inspection Stations For Detecting Nonindigenous Species Lacking Agricultural Significance: The Mexican Treefrog, Smilisca Baudinii Complex (Duméril And Bibron 1841) (Hylidae), Interdicted In Florida, Usa, From A Shipment Of Peppers, Louis A. Somma 2019 Florida State Collection of Arthropods

The Value Of Inspection Stations For Detecting Nonindigenous Species Lacking Agricultural Significance: The Mexican Treefrog, Smilisca Baudinii Complex (Duméril And Bibron 1841) (Hylidae), Interdicted In Florida, Usa, From A Shipment Of Peppers, Louis A. Somma

Papers in Herpetology

A Mexican Treefrog, Smilisca baudinii, a nonindigenous species, was interdicted for the first time from an imported shipment of peppers. The value of agriculture inspection stations used to make these interdictions is discussed. This is a single cargo interception (Stage 1: Colautti and MacIsaac 2004) and the first record for S. baudinii intercepted in Florida. Currently no evidence suggests that S. baudinii has been successfully introduced into and established in Florida, although this species could survive climatic conditions in the southern part of the state and at the scheduled destination of this shipment.

Cargo transport of alien species is a ...

Perkins Faculty Research and Special Events

Abstract-

“The Origin of Man’s Ethical Behavior” (circa October 1941) by Ernest Everett Just and Hedwig A. Schnetzler Just - is an unpublished book manuscript about the biological origins and evolution of ethical behavior, and about “the law of environmental dependence.” Missing since Just’s death in October 1941, it was found and identified in May 2018 among the collected papers of Ernest Everett Just preserved at the Howard University Moorland-Spingarn Research Center in Washington, DC. In addition to the 1996 US postage with the caption “Ernest E. Just, Biologist,” we now have reason to add two new postage stamps ...


The Interaction Of Phylogeny And Community Structure: Linking The Community Composition And Trait Evolution Of Clades, William D. Pearse, Pierre Legendre, Pedro R. Peres-Neto, T. Jonathan Davies 2019 Utah State University

The Interaction Of Phylogeny And Community Structure: Linking The Community Composition And Trait Evolution Of Clades, William D. Pearse, Pierre Legendre, Pedro R. Peres-Neto, T. Jonathan Davies

Ecology Center Publications

Aim

Community phylogenetic studies use information about the evolutionary relationships of species to understand the ecological processes of community assembly. A central premise of the field is that the evolution of species maps onto ecological patterns, and phylogeny reveals something more than species traits alone about the ecological mechanisms structuring communities, such as environmental filtering, competition, and facilitation. We argue, therefore, that there is a need for better understanding and modelling of the interaction of phylogeny with species traits and community composition.

Innovation

We outline a new approach that identifies clades that are ecophylogenetically clustered or overdispersed and assesses whether ...


Species-Area Model Predicting Diversity Loss In An Artificially Flooded Cave In Brazil, Rodrigo L. Ferreira, Thais G. Pellegrini 2019 Universidade Federal de Lavras

Species-Area Model Predicting Diversity Loss In An Artificially Flooded Cave In Brazil, Rodrigo L. Ferreira, Thais G. Pellegrini

International Journal of Speleology

Subterranean environments are poorly known regarding many ecological aspects, such as community structure and its response to different disturbances. To estimate the effects of ground area lost in a limestone cave community in Southeastern Brazil, the invertebrate fauna was sampled before 76% of the cave floor was submerged by the filling of a hydroeletric power plant reservoir. Then, a 2-year monitoring was conducted. A species-area curve based on empiric data was constructed and the z-value of the species-area equation was calculated, what allowed estimating the expected cave richness after flooding comparing with data obtained during the monitoring. The results support ...


Sex-Specific Personalities In The Purple Marsh Crab, Jillian Sterman, Jessica Barton, Panagiota Delmedico, Samantha Sweeney 2019 DePaul University

Sex-Specific Personalities In The Purple Marsh Crab, Jillian Sterman, Jessica Barton, Panagiota Delmedico, Samantha Sweeney

DePaul Discoveries

Animals are considered to possess personalities when individuals differ in behavior, and these differences are consistent between situations. Several studies have identified personalities in diverse groups but less is known about personality variation between the sexes. In this study, we examined variation in two key personality traits (boldness, activity) in female and male purple marsh crabs (Sesarma reticulatum) using a semi-field approach. Specifically, we measured boldness and activity on two consecutive days using the same behavioral assays during each time point. Consistency (personality) was determined using Kendall’s coefficient of concordance based on Spearman correlation coefficients for each behavior. The ...


Enclosures And Dichotomies: Coexistence Vs. Distance In The Poems Of John Clare, Jordan P. Finn 2019 CUNY Hunter College

Enclosures And Dichotomies: Coexistence Vs. Distance In The Poems Of John Clare, Jordan P. Finn

School of Arts & Sciences Theses

John Clare’s poetry emphasizes an affinity with environment by suspending the distinction between the inside (subject) and the outside (object). Clare’s identification with objects and perception rather than subjects and aesthetics renders his work as a prescient and radical example of ecological poetry in the Romantic period. Raymond Williams’ “green language” and Timothy Morton’s ambient poetics both cite Clare as an ideal figure for their above theories and evoke Clare as a writer who positions the environment as governing thought rather than thought governing the environment. This thesis especially relates Clare to Morton’s Ecology without Nature ...

Recovery Of Domestic Behaviors By A Parasitic Ant (Formica Subintegra) In The Absence Of Its Host (Formica Subsericea), Amber Nichole Hunter 2019 Missouri State University

Recovery Of Domestic Behaviors By A Parasitic Ant (Formica Subintegra) In The Absence Of Its Host (Formica Subsericea), Amber Nichole Hunter

MSU Graduate Theses

Dulosis is a type of social parasitism in which a parasitic ant has become dependent on captured workers (hosts) of a closely related species. Dulosis can be either facultative or obligate depending on the degree of dependence on host workers. As parasites become more specialized over evolutionary time, their domestic abilities degenerate until they become unable to survive without the host. However, the ‘lost’ behaviors may display some degree of recovery when host workers are unavailable to do the tasks. The Formica sanguinea group consists of 12 species of parasitic ants, which are all traditionally considered to be facultative parasites ...


Living On The Edge: Thermophysiology Of The Southern Flying Squirrel At Its Northern Range Margin, Vanessa R. Hensley 2019 University of Maine

Living On The Edge: Thermophysiology Of The Southern Flying Squirrel At Its Northern Range Margin, Vanessa R. Hensley

Electronic Theses and Dissertations

Climate change has the potential to upset entire ecological systems, making predictive models of the utmost importance. The incorporation of physiological parameters into predictive models not only bolsters their accuracy but also provides a mechanistic explanation for ecological changes already observed and those yet to come. North American flying squirrels, for example, have already experienced dramatic range shifts northward over recent decades, with climate change being the suspected driver. While other studies have focused on warming winter temperatures, I explored the hypothesis that rising summer temperatures were driving the observed range shifts. Unable to find a reliable population of the ...


American White Pelicans, Tommy King 2019 National Wildlife Research Center, Starkville, Mississippi

American White Pelicans, Tommy King

Wildlife Damage Management Technical Series

American white pelicans (Pelecanus erythrorhynchos, Figure 1) threaten aquaculture producers by direct predation and the spread of disease. They are also considered competition and a nuisance by some sports fishermen. Pelicans can also damage pond levees and crops, such as rice, by trampling the vegetation and depositing guano. A combination of wildlife damage management techniques is often necessary to reduce pelican damage to these resources. Aquaculture Prior to the winter of 1992, American white pelican depredations at catfish facilities in the Delta regions of Arkansas and Mississippi were limited, and birds were easily dispersed from the area. Since 1992, however ...


Invasion In The Nation: How Does Temperature During Dormancy Influence Germination Rates Of Humulus Japonicus, Anna Sapone, Briauna Bivens 2019 Carroll College

Invasion In The Nation: How Does Temperature During Dormancy Influence Germination Rates Of Humulus Japonicus, Anna Sapone, Briauna Bivens

Carroll College Student Undergraduate Research Festival

Humulus japonicus is currently in the Eastern United States, but is rapidly migrating West and heading straight for Montana. The effects of climate change have already been seen in Montana, and more changes are expected to occur in the future. These shifts could produce a climate that would allow H. japonicus to thrive on our open lands. H. japonicus is an annual invasive species that can out compete native species in riparian and floodplain habitats, altering ecosystem function. Previous studies have shown that H. japonicus seeds need some kind of cold stratification in order to break seed dormancy. For our ...

Hawaiian Honeycreeper Explosion: Monophyletic Origins Of Nectivorous Honeycreeper Beak Morphologies, Carter Anderson

Carroll College Student Undergraduate Research Festival

The goal of this study was to determine if the primary nectarivorous species of Hawai’ian Honeycreepers were a monophyletic group. A well supported phylogeny, generated using cytB of the mitochondrial genome, indicates a resolved clade of nectivore honeycreepers distinct from other lineages


Spatial And Temporal Distribution Of The Forensically Significant Blow Flies Of Los Angeles County, California, United States (Diptera: Calliphoridae), Royce T. Cumming 2019 University of Nebraska-Lincoln

Spatial And Temporal Distribution Of The Forensically Significant Blow Flies Of Los Angeles County, California, United States (Diptera: Calliphoridae), Royce T. Cumming

Dissertations & Theses in Natural Resources

Forensic entomology although not a commonly used discipline in the forensic sciences, does have its niche and when used by investigators is respected in crinimolegal investigations (Greenberg and Kunich, 2005). With many species of forensically significant insects being regionally specific, it is often difficult for forensic entomologists to as confidently translate regionally specific studies across drastically differing geographic regions (Brundage, et al., 2011).

The purpose of this study is to help create a better temporal and geographic distributional understanding of the blow fly species present in Los Angeles County, California, United States. Twenty-five locations from four ecoregions (coastal mountains, urban ...


Improving Conservation Of Declining Young Forest Birds Through Adaptive Management, Anna Buckardt Thomas 2019 University of Maine

Improving Conservation Of Declining Young Forest Birds Through Adaptive Management, Anna Buckardt Thomas

Electronic Theses and Dissertations

Early successional forest and shrubland habitats are collectively called young forest. Changes in disturbance regimes and land use conversion resulted in declines of young forest and associated wildlife across eastern North America. Conservation of declining young forest birds relies on the maintenance and creation of young forest habitats used for breeding. American Woodcock (AMWO; Scolopax minor) and Golden-winged Warbler (GWWA; Vermivora chrysoptera) are two declining young forest species. Conservation plans for both species use an adaptive management framework, which is an iterative process of planning, management actions, and monitoring and evaluation, in the context of species conservation goals. Adaptive management ...


Comparing Resource Allocation Of Fruiting Native And Invasive Species, Rheanna Meier, Suann Yang 2019 SUNY Geneseo

Comparing Resource Allocation Of Fruiting Native And Invasive Species, Rheanna Meier, Suann Yang

Papers, Posters, and Recordings

The ability of invasive plant species to rapidly overtake native flora has become a growing problem in the Northeast US and elsewhere. A variety of mechanisms contribute to this ability, such as different strategies of resource allocation to fruit and flowers in native compared to invasive species. Life history theory suggests that fruit and flower size should be inversely related, since the plant has a finite number of resources. We hypothesize that there is a ratio of fruit to flower size that allow invasive species to quickly outcompete native species—a larger flower would allow for better pollination, but a ...


Law, Biology, And Property: A New Theory Of The Endowment Effect, Owen D. Jones, Sarah F. Brosnan 2019 Georgia State University

Law, Biology, And Property: A New Theory Of The Endowment Effect, Owen D. Jones, Sarah F. Brosnan

Owen Jones

Recent work at the intersection of law and behavioral biology has suggested numerous contexts in which legal thinking could benefit by integrating knowledge from behavioral biology. In one of those contexts, behavioral biology may help to provide theoretical foundation for, and potentially increased predictive power concerning, various psychological traits relevant to law. This Article describes an experiment that explores that context.

The paradoxical psychological bias known as the endowment effect puzzles economists, skews market behavior, impedes efficient exchange of goods and rights, and thereby poses important problems for law. Although the effect is known to vary widely, there are at ...
