Scorpions Of The Horn Of Africa (Arachnida, Scorpiones). Part Xvii.Revision Of Neobuthus, With Description Of Seven New Species From Ethiopia, Kenya And Somaliland (Buthidae), František Kovařík, Graeme Lowe, Ahmed Ibrahim Awale, Hassan Sh Abdirahman Elmi, Ali Abdi Hurre Dec 2018

Scorpions Of The Horn Of Africa (Arachnida, Scorpiones). Part Xvii.Revision Of Neobuthus, With Description Of Seven New Species From Ethiopia, Kenya And Somaliland (Buthidae), František Kovařík, Graeme Lowe, Ahmed Ibrahim Awale, Hassan Sh Abdirahman Elmi, Ali Abdi Hurre

Euscorpius

New information about the taxonomy and distribution of the genus Neobuthus Hirst, 1911 is presented, based on material recently collected mainly from Somaliland, but also Djibouti and Kenya. Emended diagnoses are proposed for N. berberensis Hirst, 1911 and N. ferrugineus (Kraepelin, 1898) sensu stricto. New species described are: N. amoudensis sp. n. from Ethiopia and Somaliland; N. erigavoensis sp. n., N. factorio sp. n., N. gubanensis sp. n., N. maidensis sp. n., and N. montanus sp. n. from Somaliland; and N. kloppersi sp. n. from Kenya. This doubles the number of species in Neobuthus, unearthing a rich diversification of this ...


Revision Of The Central Asian Scorpion Genus Anomalobuthus Kraepelin, 1900, With Descriptions Of Three New Species And A Generic Synonymy (Scorpiones: Buthidae), Rolando Teruel, František Kovařík, Victor Fet Dec 2018

Revision Of The Central Asian Scorpion Genus Anomalobuthus Kraepelin, 1900, With Descriptions Of Three New Species And A Generic Synonymy (Scorpiones: Buthidae), Rolando Teruel, František Kovařík, Victor Fet

Euscorpius

We revise the Central Asian endemic genus Anomalobuthus Kraepelin, 1900, which was considered monotypic for more than 100 years until the recent addition of a second species from Iran (Teruel et al., 2014). We redefine the generic diagnosis of Anomalobuthus and reveal that it is composed of no less than six species, three of which are described as new: A. krivochatskyi, sp. n. (central Uzbekistan and extreme southern Kazakhstan), A. lowei, sp. n. (southeastern Kazakhstan), and A. pavlovskyi, sp. n. (south-central Kazakhstan and extreme northern Turkmenistan). The monotypic genus Psammobuthus Birula, 1911 (described from the Ferghana Valley at the border ...


Employing Natural History Collections In The Aid Of Conservation: Streamlining An Approach To Model Species Distributions En Masse For The Preservation Of Biodiversity, Alice Fornari Dec 2018

Employing Natural History Collections In The Aid Of Conservation: Streamlining An Approach To Model Species Distributions En Masse For The Preservation Of Biodiversity, Alice Fornari

Master's Projects and Capstones

Using species distribution models (SDMs) in Natural History Collections (NHCs) can influence how humans implement conservation changes in flora and fauna communities and ecosystems. Through the use of legacy data (old NHCs and their associated locality/collection information), data correction (background data or pseudo absences added to presence-only data), and the SDM software, Maxent (and its associated geographic information systems or GIS projected models), it has been shown that it is feasible to create a low budget protocol/setup to project the past, present and future of species population changes. This has been done in the past few decades as ...


Rediscovery Of Red Wolf Ghost Alleles In Canid Population Along The American Gulf Coast, Elizabeth Heppenheimer, Kristin Brzeski, Ron Wooten, William Waddell, Linda Y. Rutledge, Michael J. Chamberlain, Et. Al. Dec 2018

Rediscovery Of Red Wolf Ghost Alleles In Canid Population Along The American Gulf Coast, Elizabeth Heppenheimer, Kristin Brzeski, Ron Wooten, William Waddell, Linda Y. Rutledge, Michael J. Chamberlain, Et. Al.

School of Forest Resources and Environmental Science Publications

Rediscovering species once thought to be extinct or on the edge of extinction is rare. Red wolves have been extinct along the American Gulf Coast since 1980, with their last populations found in coastal Louisiana and Texas. We report the rediscovery of red wolf ghost alleles in a canid population on Galveston Island, Texas. We analyzed over 7000 single nucleotide polymorphisms (SNPs) in 60 canid representatives from all legally recognized North American Canis species and two phenotypically ambiguous canids from Galveston Island. We found notably high Bayesian cluster assignments of the Galveston canids to captive red wolves with extensive sharing ...


Population Genomic Analysis Of North American Eastern Wolves (Canic Lycaon) Support Their Conservation Priority Status, Elizabeth Heppenheimer, Ryan Harrigan, Linda Rutledge, Klaus-Peter Koepfli, Alexandra L. Decandia, Kristin Brzeski, Et. Al. Dec 2018

Population Genomic Analysis Of North American Eastern Wolves (Canic Lycaon) Support Their Conservation Priority Status, Elizabeth Heppenheimer, Ryan Harrigan, Linda Rutledge, Klaus-Peter Koepfli, Alexandra L. Decandia, Kristin Brzeski, Et. Al.

School of Forest Resources and Environmental Science Publications

The threatened eastern wolf is found predominantly in protected areas of central Ontario and has an evolutionary history obscured by interbreeding with coyotes and gray wolves, which challenges its conservation status and subsequent management. Here, we used a population genomics approach to uncover spatial patterns of variation in 281 canids in central Ontario and the Great Lakes region. This represents the first genome-wide single nucleotide polymorphism (SNP) dataset with substantial sample sizes of representative populations. Although they comprise their own genetic cluster, we found evidence of eastern wolf dispersal outside of the boundaries of protected areas, in that the frequency ...


Vegetation Characteristics And Bird Communities Associated With Singing Painted Buntings In Northwest Arkansas, Lauren Kristina Thead Dec 2018

Vegetation Characteristics And Bird Communities Associated With Singing Painted Buntings In Northwest Arkansas, Lauren Kristina Thead

Theses and Dissertations

It has been shown that bird communities are affected by the species composition and physical structure of plant communities. Within avian communities, the bird species that are the most localized in distribution tend to be the most affected by habitat changes. My research analyzed plant and bird communities found with the Painted Bunting (Passerina ciris Linnaeus), a locally common but declining species throughout much of its range. First, I describe vegetation characteristics associated with singing male Painted Buntings in northwest Arkansas. I categorized field sites with singing male Painted Buntings as either managed for wildlife or unmanaged, based on land-use ...

Crabwalkers and sand minnows: Searching for psammophilic mayflies in the central and western states (& provinces)1

Greg Courtney Department of Entomology, Iowa State University, Ames, Iowa, USA

Motivated by a number of collaborative photography projects with Steve Marshall (e.g., Courtney & Marshall, 2019), I have devoted a bit of time recently to searching for non-dipteran aquatic insects. Among the ongoing projects is a book on which I am not only lead author but in charge of several chapters focused on taxa outside my usual bailiwick (e.g., Ephemeroptera!). Thankfully, Steve has already established an excellent template for such a book ...


Effect Of Macrograzers (Campostoma Spp. And Faxonius Spp.) On Periphyton In Ozark Streams With Considerations Given To Macrograzer Biomass, Phosphorus, And Season: Mensurative And Manipulative Studies, Kayla R. Sayre Dec 2018

Effect Of Macrograzers (Campostoma Spp. And Faxonius Spp.) On Periphyton In Ozark Streams With Considerations Given To Macrograzer Biomass, Phosphorus, And Season: Mensurative And Manipulative Studies, Kayla R. Sayre

Theses and Dissertations

Nutrient and benthic algal biomass relationships can guide numeric nutrient criteria development in lotic systems. However, herbivorous macrograzers may confound this relationship by reducing the slope of the positive relationship between nutrients and periphyton biomass in streams. I conducted a mensurative field study to determine if stoneroller and crayfish abundance related to algal biomass at varying nutrient concentrations and manipulated macrograzer presence with electrical exclosures in streams to examine macrograzer effects on algal biomass and understand whether these effects on periphyton varied with total phosphorus (TP) or season. Macrograzer density was quantified across a TP gradient (n=15 streams; range ...


Painted Ferocity: The Social Behaviors Of African Wild Dogs, Threats To Survival, And Resulting Conservation Initiatives, Alexis Valdes Dec 2018

Painted Ferocity: The Social Behaviors Of African Wild Dogs, Threats To Survival, And Resulting Conservation Initiatives, Alexis Valdes

Senior Honors Theses

African Wild Dogs (Lycaon pictus) are an endangered species of canid from Sub-Saharan Africa. They are very social communal hunters, and are capable of chasing down prey for long stretches of time. Wild dogs benefit a savannah ecosystem by regulating the populations of their prey so that it does not become unhealthy and overgrown. Like many organisms, wild dogs are also in competition with other predators for resources, namely lions and hyenas, who are capable of stealing their kills and occasionally injuring and killing them. Due to the depletion of their wild prey, wild dogs may also prey upon farmers ...


Bats Of Saint Lucia, Lesser Antilles, Scott C. Pedersen, Gary G. Kwiecinski, Hugh H. Genoways, Roxanne J. Larsen, Peter A. Larsen, Carleton J. Phillips, Robert J. Baker Nov 2018

Bats Of Saint Lucia, Lesser Antilles, Scott C. Pedersen, Gary G. Kwiecinski, Hugh H. Genoways, Roxanne J. Larsen, Peter A. Larsen, Carleton J. Phillips, Robert J. Baker

Mammalogy Papers: University of Nebraska State Museum

Eight species of bat have been previously recorded from the island of Saint Lucia: Noctilio leporinus, Monophyllus plethodon, Artibeus jamaicensis, Brachyphylla cavernarum, Ardops nichollsi, Sturnira paulsoni, Molossus molossus, and Tadarida brasiliensis. Herein, we add a ninth species to the fauna—Pteronotus davyi. These nine species represent nine genera from four families: Noctilionidae, Mormoopidae, Phyllostomidae, and Molossidae. This fauna includes four trophic guilds: N. leporinus (piscivore/insectivore), M. plethodon (nectarivore/pollenivore), A. jamaicensis × schwartzi, B. cavernarum, A. nichollsi, and S. paulsoni (frugivores), and P. davyi, M. molossus, and T. brasiliensis (insectivores). Based on its geographic location, the bat fauna of St ...


Courtship Behavior, Communication, And Copulation In Tigrosa Annexa, Samuel White Nov 2018

Courtship Behavior, Communication, And Copulation In Tigrosa Annexa, Samuel White

Scholars Week

The evolution of multimodal communication, where signalers use multiple signal components in multiple sensory modalities, has become the subject of investigation by many researchers. Signaling puts males at risk of predation, so why do males of some species evolve extra signals that may increase this risk? In some wolf spider species, males incorporate many visual and vibrational signals into a display that they use to attract a female for mating. Female spiders are often aggressive toward courting males and so the male display also functions to decrease the odds of cannibalism. Female wandering spiders deposit silk containing pheromones that communicate ...


Alternative Genes For Exploring Ranavirus Phylogenetics: Four Core Genes Compared To The Major Capsid Protein And The Whole Genome., Abigale Garner Nov 2018

Alternative Genes For Exploring Ranavirus Phylogenetics: Four Core Genes Compared To The Major Capsid Protein And The Whole Genome., Abigale Garner

Georgia Undergraduate Research Conference (GURC)

The Iridoviridae is a family of virus that infects invertebrates and poikilothermic vertebrates such as amphibians, reptiles, and fish. Ranavirus is one of the five genera within the Iridoviridae. Ranavirus infections have been seen on every continent. The ranaviruses have 26 core genes, but our study focuses on the utility of: an immediate early protein ICP-46 [open reading frame (ORF) 91R in Frog virus 3 (FV3)]; a transcription elongation factor TIIS (ORF 81R in FV3); Evrl/Air family protein (ORF 88R in FV3); and a hypothetical/putative protein of unknown function (ORF 94R in FV3) as alternative genes for phylogenetic ...

Faculty Publications from the Harold W. Manter Laboratory of Parasitology

Natural history collections spanning multiple decades provide fundamental historical baselines to measure and understand changing biodiversity. New technologies such as next generation DNA sequencing have considerably increased the potential of museum specimens to address significant questions regarding the impact of environmental changes on host and parasite/pathogen dynamics. We developed a new technique to identify intestinal helminth parasites and applied it to shrews (Eulipotyphla: Soricidae) because they are ubiquitous, occupy diverse habitats, and host a diverse and abundant parasite fauna. Notably, we included museum specimens preserved in various ways to explore the efficacy of using metabarcoding analyses that may enable ...
