A New Island Species Of Centruroides Marx, 1890 (Scorpiones: Buthidae) From The Southwestern Caribbean, Rolando Teruel, Brandon Myers Dec 2017

A New Island Species Of Centruroides Marx, 1890 (Scorpiones: Buthidae) From The Southwestern Caribbean, Rolando Teruel, Brandon Myers

Euscorpius

Herein we describe a new species of the Buthidae scorpion genus Centruroides Marx, 1890. It occurs at least in two small offshore islands of the southwestern Caribbean: Cozumel in Mexico and Guanaja in Honduras, based upon type specimens from the former and photographic evidence from the latter. It belongs in the "gracilis" species-group and is most closely related to both Centruroides gracilis (Latreille, 1805) and Centruroides nigrescens (Pocock, 1898).

The North American Quails, Partridges, And Pheasants, Paul A. Johnsgard Oct 2017

The North American Quails, Partridges, And Pheasants, Paul A. Johnsgard

Zea E-Books Collection

This book documents the biology of six species of New World quails that are native to North America north of Mexico (mountain, scaled, Gambel’s, California, and Montezuma quails, and the northern bobwhite), three introduced Old World partridges (chukar, Himalayan snowcock, and gray partridge), and the introduced common (ring-necked) pheasant. Collectively, quails, partridges, and pheasants range throughout all of the continental United States and the Canadian provinces. Two of the species, the northern bobwhite and ring-necked pheasant, are the most economically important of all North American upland game birds. All of the species are hunted extensively for sport and are highly …

Climate-Driven Habitat Shifts In South America: Biogeography, Historical Demography, And Population Genomics Of Anole Lizards, Ivan Prates Sep 2017

Climate-Driven Habitat Shifts In South America: Biogeography, Historical Demography, And Population Genomics Of Anole Lizards, Ivan Prates

Dissertations, Theses, and Capstone Projects

Shifts in the geographic distribution of habitats over time can promote dispersal and vicariance, thereby influencing large-scale biogeographic patterns and ecological processes. The establishment of corridors of suitable habitat across previously disjunct yet ecologically similar regions has been widely linked to climate change over time. Such climate-mediated habitat changes may have played a key role in the assembly of tropical biotas, including those of Amazonia and the coastal Atlantic Forest in South America, two of the most diverse ecosystems on Earth. The history of biogeographic associations between tropical rainforest habitats in response to former climatic shifts, as well as their …

The Scorpion Fauna Of Mona Island, Puerto Rico (Scorpiones: Buthidae, Scorpionidae), Rolando Teruel, Mel J. Rivera, Alejandro J. Sánchez Aug 2017

The Scorpion Fauna Of Mona Island, Puerto Rico (Scorpiones: Buthidae, Scorpionidae), Rolando Teruel, Mel J. Rivera, Alejandro J. Sánchez

Euscorpius

The scorpion fauna of the small Mona Island (= Isla de Mona), located roughly midway between Hispaniola and Puerto Rico and administratively belonging to the latter, is herein revised. Three species are confirmed to occur: the buthids Centruroides bani Armas et Marcano Fondeur, 1987 and Heteroctenus abudi (Armas et Marcano Fondeur, 1987), plus the diplocentrine scorpionid Cazierius garridoi Armas, 2005. The previously recorded Heteronebo sp. is reexamined and deemed a mislabeled specimen of Heteronebo portoricensis Francke, 1978 from adjacent Puerto Rico. Also, Centruroides mariaorum Santiago-Blay, 2009 is demonstrated to be a junior synonym of C. bani (implying the first demonstrable …

Revalidation Of Three Recently Synonymized Cuban Species Of Heteroctenus Pocock, 1893 (Scorpiones: Buthidae: Centruroidinae), Luis F. De Armas Jul 2017

Revalidation Of Three Recently Synonymized Cuban Species Of Heteroctenus Pocock, 1893 (Scorpiones: Buthidae: Centruroidinae), Luis F. De Armas

Euscorpius

The scorpion genus Heteroctenus Pocock, 1893 was restored from synonymy with Rhopalurus in a recent revision by Esposito et al. (2017). Here, we restore two eastern Cuban species Heteroctenus melloleitaoi (Teruel et Armas, 2006) and H. aridicola (Teruel et Armas, 2012) as valid species. They were synonymized by Esposito et al. (2017) under Heteroctenus junceus (Herbst, 1800), without examination of corresponding specimens and with erroneous interpretations of some aspects of the original descriptions. Heteroctenus granulimanus (Teruel, 2006) is also restored as a valid species. The subfamily Rhopalurusinae Bücherl, 1971 is regarded as a junior synonym of Cen-truroidinae Kraus, 1955.

The Second Record Of A Relict Akrav Israchanani Levy, 2007 (Scorpiones: Akravidae) From Levana Cave, Israel, Victor Fet, Michael E. Soleglad, Sergei L. Zonstein, Israel Naaman, Shlomi Lubaton, Boaz Langford, Amos Frumkin Jun 2017

The Second Record Of A Relict Akrav Israchanani Levy, 2007 (Scorpiones: Akravidae) From Levana Cave, Israel, Victor Fet, Michael E. Soleglad, Sergei L. Zonstein, Israel Naaman, Shlomi Lubaton, Boaz Langford, Amos Frumkin

Euscorpius

We report the remnants of five new scorpion specimens discovered dead in Levana Cave in Israel in December 2015. We confirm that they belong to the relict scorpion Akrav israchanani Levy, 2007 (Akravidae), famously described from the neighboring Ayyalon Cave, also from dead specimens. The details of morphology of the new specimens are given; they match completely the characters of A. israchanani redescribed by Fet, Soleglad & Zonstein (2011). This second record indicates a wider distribution of this unique cave scorpion, which, however, is extinct in both caves. There is still no evidence that live populations of this species exist.

A Global Community Effort To Decipher The Unique Biology Of Annual Killifish, Nibia Berois, Graciela Garcia, Rafael O. De Sá Jun 2017

A Global Community Effort To Decipher The Unique Biology Of Annual Killifish, Nibia Berois, Graciela Garcia, Rafael O. De Sá

Biology Faculty Publications

Over the past 50 years, annual killifishes arose as alternative model organisms for studies of vertebrate biology. The annual fish offers exceptional advantages for studies of genetics, genomics, developmental biology, population dynamics, ecology, biogeography, and evolution. They inhabit extremely variable freshwater environments in Africa and South America, have a short lifespan and a set of unique and fascinating developmental characteristics. Embryos survive within the dry substrate during the dry season, whereas the adult population dies. Thus, the survival of the populations is entirely dependent on the buried embryos that hatch the next rainy season. Although Old and New World species …

Cranial Morphological Distinctiveness Between Ursus Arctos And U. Americanus, Benjamin James Hillesheim May 2017

Cranial Morphological Distinctiveness Between Ursus Arctos And U. Americanus, Benjamin James Hillesheim

Electronic Theses and Dissertations

Despite being separated by millions of years of evolution, black bears (Ursus americanus) and brown bears (Ursus arctos) can be difficult to distinguish based on skeletal and dental material alone. Complicating matters, some Late Pleistocene U. americanus are significantly larger in size than their modern relatives, obscuring the identification of the two bears. In the past, fossil bears have been identified based on differences in dental morphology or size. This study used geometric morphometrics to look at overall differences in cranial shape and used step-wise discriminant analysis to identify specific characters that distinguish cranial morphology between …

Some Taxonomic Corrections To The Genus Tityus C. L. Koch, 1836 (Scorpiones: Buthidae) In Hispaniola, Greater Antilles, Rolando Teruel Mar 2017

Some Taxonomic Corrections To The Genus Tityus C. L. Koch, 1836 (Scorpiones: Buthidae) In Hispaniola, Greater Antilles, Rolando Teruel

Euscorpius

In the present paper, the taxonomic status of several Hispaniolan members of the genus Tityus C. L. Koch, 1966 is revised after examination of almost all primary types and abundant supplementary material. This resulted in six new synonymies, which involve both extant and fossil species.

Patterns Of Morphological And Molecular Evolution In The Antillean Tree Bat, Ardops Nichollsi (Chiroptera: Phyllostomidae), Roxanne J. Larsen, Peter A. Larsen, Caleb D. Phillips, Hugh H. Genoways, Gary G. Kwiecinski, Scott C. Pedersen, Carleton J. Phillips, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

Species endemic to oceanic islands offer unique insights into the mechanisms underlying evolution and have served as model systems for decades. Often these species show phenotypic variation that is correlated with the ecosystems in which they occur and such correlations may be a product of genetic drift, natural selection, and/or environmental factors. We explore the morphologic and genetic variation within Ardops nichollsi, a species of phyllostomid bat endemic to the Lesser Antillean islands. Ardops nichollsi is an ideal taxon to investigate the tempo of evolution in Chiroptera, as it: is a recently derived genus in the family Phyllostomidae; contains …

The Missing Piece Of The Puzzle Solved: Heteronebo Pocock, 1899 (Scorpiones: Scorpionidae) Occurs At Isla De Pinos, Cuba, Rolando Teruel, Tomás M. Rodríguez-Cabrera

Euscorpius

The diplocentrine scorpion genus Heteronebo Pocock, 1899 is recorded herein for the first time from Isla de Pinos, southwestern Cuba. A total of 15 specimens of Heteronebo bermudezi (Moreno, 1938) were collected in two nearby localities of the southern coast of the island, where it occurs in exactly the same habitat previously known for this species in Guanahacabibes Peninsula and two cays of Canarreos Archipelago. The allegedly polytypic status of this species is also revised and full species rank is restored to the subspecies Heteronebo bermudezi morenoi (Armas, 1973). An updated distribution map of H. bermudezi is provided.

Centruroides Thorellii (Scorpiones: Buthidae): Traveling From Guatemala To England Without A Passport, Rony E. Trujillo, Luis F. De Armas, Darren Mansfield Feb 2017

Centruroides Thorellii (Scorpiones: Buthidae): Traveling From Guatemala To England Without A Passport, Rony E. Trujillo, Luis F. De Armas, Darren Mansfield

Euscorpius

We recorded a pregnant female of the Central American bark stripped scorpion Centruroides thorellii (Kraepelin, 1891), which arrived to England as a stowaway in the bag of a woman that previously visited the Departments of Sacatepéquez, Sololá and San Marcos, Guatemala. On January 2, this C. thorellii female had a litter of three off-spring and three infertile eggs, but she has eaten them, probably as consequence of the stress caused by the hard travel and the environmental changes. We provide a map with the geographical distribution of this species and photos of the female detected in a British train.

Genomic Perspectives On Amphibian Evolution Across Multiple Phylogenetic Scales, Paul Michael Hime Jan 2017

Genomic Perspectives On Amphibian Evolution Across Multiple Phylogenetic Scales, Paul Michael Hime

Theses and Dissertations--Biology

Genomes provide windows into the evolutionary histories of species. The recent accessibility of genome-scale data in non-model organisms and the proliferation of powerful statistical models are now providing unprecedented opportunities to uncover evolutionary relationships and to test hypotheses about the processes that generate and maintain biodiversity. This dissertation work reveals shallow-scale species boundaries and population genetic structure in two imperiled groups of salamanders and demonstrates that the number and information content of genomic regions used in species delimitation exert strong effects on the resulting inferences. Genome scans are employed to test hypotheses about the mechanisms of genetic sex determination in …

Rewiring Metabolism Under Oxygen Deprivation: Naked Mole-Rats Evolved A Means To Cope With Anoxia, Jay F. Storz, Grant B. Mcclelland Jan 2017

Rewiring Metabolism Under Oxygen Deprivation: Naked Mole-Rats Evolved A Means To Cope With Anoxia, Jay F. Storz, Grant B. Mcclelland

Jay F. Storz Publications

When faced with a reduced availability of oxygen in the environment (hypoxia), vertebrates can make a variety of respiratory, cardiovascular, and hematological adjustments to ensure an uninterrupted supply of oxygen to the cells of metabolizing tissues (1, 2). These are adaptive solutions for “aerobic organisms in an aerobic world” (3). Coping with the complete absence of oxygen (anoxia) requires more fundamental alterations of cellular metabolism that are typically nothing more than emergency stopgap measures to buy time until the oxygen supply is (hopefully) reestablished (4). On page 307 of this issue [Science 356 (6335)], Park et al. (5) identify a …

Are Weevils Picky Eaters? Community Structure And Host Specificity Of Neotropical Saproxylic Beetles (Coleoptera: Curculionidae), Jhunior A. Morillo Jan 2017

Are Weevils Picky Eaters? Community Structure And Host Specificity Of Neotropical Saproxylic Beetles (Coleoptera: Curculionidae), Jhunior A. Morillo

Dissertations and Theses

Abstract Primary saproxylic beetles play a major role in forest nutrient cycling and making deadwood accessible to other decomposers. Understanding beetle host preferences and patterns of community assembly is critical for their conservation, and for predicting which species might become invasive. This project aims to investigate the ecological and host specificity, as well as the community composition of curculionids in a mosaic of old-growth (OG) and secondary forest on the Osa Peninsula, Costa Rica. The subfamily Scolytinae was expected to be the most species-rich and abundant. Ambrosia beetles were expected to have more generalist species than other curculionids. Old growth …

¬Multilocus Phylogeny Of The Lichen Family Megasporaceae, Tim B. Wheeler Jan 2017

¬Multilocus Phylogeny Of The Lichen Family Megasporaceae, Tim B. Wheeler

Graduate Student Theses, Dissertations, & Professional Papers

The lichen symbiosis is one of the oldest studied mutualisms; in fact, Frank and De Bary coined the term "symbiosis" while studying lichens (Frank, 1877; De Bary 1879). The widespread, stable association between the mycobiont and photobiont in lichens offers an ideal system for the study of co-evolution. The recent application of molecular data to lichens has begun to unveil the complexities involved in these associations (Upreti et al. 2015, Spribille et al. 2016). Lichenized fungi make up a huge fraction of fungal diversity (Nash 2008), yet very little is known of their genetic diversity. Fungal taxonomy is notoriously difficult …

Neutral And Adaptive Genetic Variation In North American Hardwood Tree Species, Sudhir Khodwekar Jan 2017

Neutral And Adaptive Genetic Variation In North American Hardwood Tree Species, Sudhir Khodwekar

Dissertations, Master's Theses and Master's Reports

'Northern Hardwoods,’ are a characteristic composition of multiple tree species and a part of the rich and diverse northeastern forests. Hardwoods e.g. oaks (Quercus: Fagaceae and Sugar maple), serve as foundation species and offer ecological and economical gains to wildlife and humans. Most of the forest trees go through many biotic and abiotic stresses, for example climate change in their long life span. To overcome these threats and to adapt to changing conditions, tree species need to maintain variation especially in adaptive genes. Therefore, it is necessary to analyze genetic diversity within forest tree populations and take appropriate …
