Evolution Of Alu Elements In The Saimiri And Papio Lineages Of Primates, 2018 Louisiana State University and Agricultural and Mechanical College
Evolution Of Alu Elements In The Saimiri And Papio Lineages Of Primates, Jasmine Nicole Brown Baker
LSU Doctoral Dissertations
Alu elements are approximately 300 base pair (bp) primate specific non- autonomous retrotransposons. Alu elements, a short interspersed element (SINE), account for high copy numbers in all primate genomes. Numerous Alu element subfamilies have undergone varying degrees of activity and amplification within primates. Identification of these subfamilies has proved to be very informative in elucidating phylogenies and as phylogenomic markers. Squirrel monkeys, genus Saimiri, are one of the most well-known neotropical primates and the second most commonly used laboratory monkey. Squirrel monkey species diverged approximately 1.5 million years ago and are native to South America. Despite being well-known, there …

The Inland Pacific Northwest (IPNW) encompasses 1. 6 million cropland hectares and is a major wheat-producing area in the western United States. The climate throughout the region is semi-arid, making the availability of water a significant challenge for IPNW agriculture. Much attention has been given to uncovering the effects of water stress on the physiology of wheat and the dynamics of its soilborne diseases. In contrast, the impact of soil moisture on the establishment and activity of microbial communities in the rhizosphere of dryland wheat remains poorly understood. We addressed this gap by conducting a three-year field study involving wheat …

Grooming Behaviors Of, 2018 University of South Florida
Grooming Behaviors Of, Lauren N. Williams
USF Tampa Graduate Theses and Dissertations
The giant freshwater shrimp, Macrobrachium rosenbergii is a large species of prawn grown extensively in aquaculture settings. A social hierarchy exists within the males of this species, representing three distinct male morphotypes. These male morphotypes differ in their behavior, physiology, and morphology and include the largest blue-clawed males (BC males), moderately- sized orange-clawed males (OC males), and the undifferentiated small-clawed males (SM males). All individuals of this species perform grooming behaviors to rid themselves of body fouling which can impede important functions such as movement, respiration, chemoreception, and reproduction. Grooming behaviors in crustaceans often utilize specialized structures called setae, which …
A Biogeographic Perspective On The Evolution Of Fire Syndromes In Pine Trees (Pinus: Pinaceae), 2018 The Nature Conservancy
A Biogeographic Perspective On The Evolution Of Fire Syndromes In Pine Trees (Pinus: Pinaceae), Kevin J. Badik, Joshua P. Jahner, Joseph S. Wilson
Biology Faculty Publications
Our goals were to explore the relationship between biogeography and the evolution of fire-adaptive syndromes in the genus Pinus. We used a previously published time-calibrated phylogeny and conducted ancestral trait reconstruction to estimate the likely timing of diversification in Pinus, and to determine when fire-adaptive syndromes evolved in the lineage. To explore trait conservation among fire syndromes and to investigate historical biogeography, we constructed ancestral state reconstructions using the program RASP and estimated the degree of conservatism for fire-adapted traits in the program BaTS. Our reconstructions suggest that the Bering land bridge, which connected North America and Asia, probably played …
Gene Co-Occurrence Networks Reflect Bacteriophage Ecology And Evolution, 2018 Loyola University Chicago
Gene Co-Occurrence Networks Reflect Bacteriophage Ecology And Evolution, Jason W. Shapiro, Catherine Putonti
Biology: Faculty Publications and Other Works
Bacteriophages are the most abundant and diverse biological entities on the planet, and new phage genomes are being discovered at a rapid pace. As more phage genomes are published, new methods are needed for placing these genomes in an ecological and evolutionary context. Phages are difficult to study by phylogenetic methods, because they exchange genes regularly, and no single gene is conserved across all phages. Here, we demonstrate how gene-level networks can provide a high-resolution view of phage genetic diversity and offer a novel perspective on virus ecology. We focus our analyses on virus host range and show how network …
Testing For The Presence Of Botryosphaeria Dothidea In Branches Of Ceanothus Spinosus Undergoing Dieback, 2018 Pepperdine University
Testing For The Presence Of Botryosphaeria Dothidea In Branches Of Ceanothus Spinosus Undergoing Dieback, Brandon R. Grinovich, Chelsea N. Puncochar, Katarina L. Carter, Stephen D. Davis, Rodney L. Honeycutt, Talia A. Cao, Karagan L. Smith
Featured Research
Botryosphaeria dothidea is an opportunistic pathogen found in some of the cavitated branches of the vegetation in the Santa Monica Mountains. In this study, we focused on finding the presence of Botryosphaeria dothidea in Ceanothus spinosus located on Pepperdine University’s campus. We wanted to test this hypothesis because we observed a large amount of dieback in the Ceanothus spinosus population and wanted to identify a possible contributor. Because of the large number of cavitated branches the Ceanothus spinosus contained, we hypothesized they contained fungus. To test this, we took twenty samples of twenty different Ceanothus spinosus, isolated the fungus …
Does Body Size Affect Fitness The Same Way In Males And Females? A Test Of Multiple Fitness Components, 2018 Brigham Young University - Provo
Does Body Size Affect Fitness The Same Way In Males And Females? A Test Of Multiple Fitness Components, Ashlee N. Smith, Mark C. Belk
Faculty Publications
Body size generally has an important relationship with fitness, whereby larger body size leads to an increase in fitness through competition, reproductive output and survivorship. However, the traits through which body size increases fitness often differ between the sexes. We tested for the effects of body size on fitness in both sexes using three separate experiments on competitive ability, reproductive output and starvation resistance in the burying beetle Nicrophorus marginatus. Results varied between sexes as follows: (1) larger body size increased competitive ability differentially between sexes; (2) female body size, but not male body size, significantly affected reproductive output …

Stochastic Event Alters Gelatinous Zooplankton Community Structure: Impacts Of Hurricane Sandy In A Mid-Atlantic Estuary, 2018 Montclair State University
Stochastic Event Alters Gelatinous Zooplankton Community Structure: Impacts Of Hurricane Sandy In A Mid-Atlantic Estuary, Paul Bologna, John Gaynor, Robert Meredith, Dena Restaino, Christie Barry
Department of Biology Faculty Scholarship and Creative Works
Climate change has increased hurricane activity and intensity, leading to greater destructive forces impacting coastal communities. Barnegat Bay, New Jersey, USA, is a shallow Mid-Atlantic estuary with considerable anthropogenic development which shows vulnerability to elevated storm surges and coastal flooding. Gelatinous zooplankton were sampled monthly in the summer prior to Hurricane Sandy in October 2012, with the community dominated by 2 species, Chrysaora quinquecirrha and Mnemiopsis leidyi. These 2 species showed inverse distributions, with C. quinquecirrha dominating in the northern, lower-salinity region and M. leidyi abundant in the southern, high-salinity region of the estuary, with significant top-down control of M. …
Ecosystem Function And Phenotypic Variation In Spartina Alterniflora Salt Marshes, 2018 University of South Florida
Ecosystem Function And Phenotypic Variation In Spartina Alterniflora Salt Marshes, Sandra E. Voors
USF Tampa Graduate Theses and Dissertations
Biodiversity is important to ecosystem function at many scales, and variation functional traits within a species can potentially influence ecosystem functioning by altering nutrient cycling dynamics. High population extinction rates are resulting in a rapid loss of within-species biodiversity, so there is a need to better understand the importance of intraspecific variation to ecosystem-level processes. Tidal salt marshes are ideal ecosystems for investigating intraspecific variation in plant-nutrient relationships because they are dominated by a monoculture of the foundation species Spartina alterniflora, with distinct phenotypes that correspond to environmental gradients across the marsh. We conducted a field survey of existing …
Whence And Whither: Acoustic Variability And Biogeography Of Tarsiers In North Sulawesi, 2018 Portland State University
Whence And Whither: Acoustic Variability And Biogeography Of Tarsiers In North Sulawesi, Olivia Clare Kulander
Dissertations and Theses
The morning duet calls of eastern tarsiers (Tarsius spp.) in North Sulawesi were recorded and analyzed to examine the effects of geography and geologic history on their call structure. Tarsius species exhibit interspecifically variable duet calls shown to correlate with species differentiation and distribution. They are distributed across Sulawesi, a biogeographically complex island in the Indonesian archipelago, where tectonic activity and multiple glaciations during the Pleistocene generated and modified barriers to their dispersal and gene flow.
Recordings were made at ten locations from November of 2012 through June of 2014. Two locations were categorized as mainland, while eight island …
Comparative Meiotic Cytology Among Drosophila Species, 2018 DePaul University
Comparative Meiotic Cytology Among Drosophila Species, Ahmed Folademi Majekodunmi
College of Science and Health Theses and Dissertations
Physical connections established by homologous recombination are normally sufficient to establish proper co-orientation of chromosomes during prometaphase of female meiosis I. Nonexchange chromosomes can still segregate because they are connected by heterochromatic threads, which are thought to connect homologous chromosomes and ensure co-orientation in the absence of a chiasma. In Drosophila, the nonexchange chromosomes (such as the Muller F element, also called the “dot chromosome,” which never undergoes recombination) move out on the spindle during prometaphase I, and can be found positioned between the spindle poles and the exchange chromosomes at the metaphase plate. By metaphase I arrest, these …

Valued readers, it is with a heavy heart that I inform you that this is the last issue of Killi-Data News. The good news is that we will be back as Killifish Research Review. The dissolution of Killi-Data International created a prob- lem: how can the newsletter of a defunct organization live on without that organization? But other additional problems were building in the background. The first issue numbered 15 pages. The previous issue was 28 pages. The number of killifish related papers is increasing while time on our end (the editorial team) is running out. It takes a lot …

Many interesting papers have been published over the last three months. The large volume of papers coupled with the start of the new college semester (and the workload it brings) delayed this issue of Killi-Data News. But better late than never—or so I hope! In this issue Richard van der Laan provides an insightful review of the recent Aphanius papers as to their taxonomic implications and questions. The systematic issues he raises show the importance of the Molecular project: we need to get more samples of the various cyprinodontiforme families to resolve unsettled systematic and taxonomic issues. In the Next …
