Genetic Diversity Of Neotropical Myotis (Chiroptera: Vespertilionidae) With An Emphasis On South American Species, Roxanne J. Larsen, Michelle C. Knapp, Hugh H. Genoways, Faisal Ali Anwarali Khan, Peter A. Larsen, Don E. Wilson, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

Background: Cryptic morphological variation in the Chiropteran genus Myotis limits the understanding of species boundaries and species richness within the genus. Several authors have suggested that it is likely there are unrecognized species-level lineages of Myotis in the Neotropics. This study provides an assessment of the diversity in New World Myotis by analyzing cytochrome-b gene variation from an expansive sample ranging throughout North, Central, and South America. We provide baseline genetic data for researchers investigating phylogeographic and phylogenetic patterns of Myotis in these regions, with an emphasis on South America.

Methodology and Principal Findings: Cytochrome-b sequences were …


An Assessment Of Stable Hydrogen-Isotope Analysis Methods To Assign Geographic Origin To Migratory Red-Tailed Hawks (Buteo Jamaicensis), Carla Marie Ahlschwede May 2011

An Assessment Of Stable Hydrogen-Isotope Analysis Methods To Assign Geographic Origin To Migratory Red-Tailed Hawks (Buteo Jamaicensis), Carla Marie Ahlschwede

Department of Environmental Studies: Undergraduate Student Theses

Stable-hydrogen isotopes are becoming an increasingly popular method of studying migratory birds, though sample preparation methods may affect results.  In this study I examined feathers from red-tailed hawks (Buteo jamaicensis) to determine the relationship between measure of δD due to inter-feather variation or drying methods, assessed the accuracy of results by using two birds of known-origin and estimated possible natal origins of migratory red-tailed hawks.  Two feathers per individual were taken from 81 wild hawks caught at Hitchcock Nature Center near Crescent IA and from 2 rescued red-tailed hawks, Raptor Recovery Nebraska near Eagle, NE. 119 of the …

University of Nebraska State Museum: Mammalogy Papers

Almost nothing is known concerning the chiropteran fauna on the Grenadine Islands, a chain of islands between St. Vincent and Grenada located near the southern end of the Lesser Antilles. Previously, only a single species—Glossophaga longirostris—had been reported from the Grenadines. Our research, conducted on 4 occasions over the period of 1980 to 2006, provided museum vouchers and genetic specimens for the addition of 4 other species to the known fauna of these islands—Noctilio leporinus, Artibeus lituratus, Artibeus schwartzi, and Molossus molossus. The Grenadines, being situated between St. Vincent and Grenada, occupy an important zoogeographic position. …

Preliminary Analysis Of The Ecology And Geography Of The Asian Nuthatches (Aves: Sittidae), Shaily Menon, Zafar-Ul Islam, Jorge Soberon, A. Townsend Peterson Dec 2008

Preliminary Analysis Of The Ecology And Geography Of The Asian Nuthatches (Aves: Sittidae), Shaily Menon, Zafar-Ul Islam, Jorge Soberon, A. Townsend Peterson

Peer Reviewed Publications

We explored distributions of Asian nuthatch species in ecological and geographic space using ecological niche modeling based on occurrence data associated with specimens and observations. Nuthatches represent a well-defined clade occurring throughout the Northern Hemisphere, but are most diverse in southern Asia where 15 of the 24 species occur and where the lineage is believed to have evolved. Species richness was focused in a narrow east-west band corresponding to the forested parts of the Himalayas with a maximum number of nine species predicted present in these foci. The distributional predictions have a mid-elevation focus with highest species diversity between 1,000 …


Terrapene Ornata (Ornate Box Turtle) Predation On Cliff Swallows, Mary Bomberger Brown, Charles R. Brown Jan 2008

Terrapene Ornata (Ornate Box Turtle) Predation On Cliff Swallows, Mary Bomberger Brown, Charles R. Brown

School of Natural Resources: Faculty Publications

During a 25-year study of Cliff Swallows (Petrochelidon pyrrhonota) in southwestern Nebraska, we observed Terrapene ornata prey, or attempt to prey, on swallows. On one occasion as large numbers of birds flushed and hit the net, the weight of the birds pulled the net down to ground level. One T. ornata, which was seen regularly at the colony, approached one adult Cliff Swallow that was very low in the net and killed it by biting and eating its head. After killing the bird, the turtle walked away carrying the head.


Mating Systems, Copulatory Organ Size, And Scaling Relationship In Mollies (Poecilia Spp.), Martha Divver, Eric T. Schultz Jan 2008

Mating Systems, Copulatory Organ Size, And Scaling Relationship In Mollies (Poecilia Spp.), Martha Divver, Eric T. Schultz

EEB Articles

Copulatory organs rapidly evolve and are subject to complex selective pressures affecting mating success. One feature of copulatory organs that is subject to such selective pressures is size. Benefits of longer organs may include greater signal effectiveness in courtship and longer ‘reach’ when attempting copulations with evasive females. Costs of longer organs may include impaired locomotion, increased energetic cost or reduced mechanical compatibility with female genitalia. The optimal size for a copulatory organ may vary with mating behavior. The objective of this study is to examine among-species variability in copulatory organ size, body size and the relationship between copulatory organ …

High Rate Of Recent Transposable Element–Induced Adaptation In Drosophila Melanogaster, Josefa Gonzalez, Kapa Lenkov, Mikhail Lipatov, J. Michael Macpherson, Dmitri A. Petrov

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Although transposable elements (TEs) are known to be potent sources of mutation, their contribution to the generation of recent adaptive changes has never been systematically assessed. In this work, we conduct a genome-wide screen for adaptive TE insertions in Drosophila melanogaster that have taken place during or after the spread of this species out of Africa. We determine population frequencies of 902 of the 1,572 TEs in Release 3 of the D. melanogaster genome and identify a set of 13 putatively adaptive TEs. These 13 TEs increased in population frequency sharply after the spread out of Africa. We argue that …

University of Nebraska State Museum: Mammalogy Papers

We phylogenetically analyze 705 base pairs of the cytochrome-b gene and 351 amplified fragment length polymorphism (AFLP) bands from populations of the karyotypically variable Wagner’s bonneted bat, Eumops glaucinus, and the Florida bonneted bat, Eumops floridanus (Chiroptera: Molossidae). Three karyotypes have been documented across the range of E. glaucinus, and we report that the karyotype from Cuba is morphologically similar to that from Jamaica. A 4th karyotype is present in specimens from western Ecuador. Three distinct lineages are present in both the cytochrome-b and AFLP trees. One lineage is restricted to western Ecuador and exhibits cytochrome-b …

Bats Of Jamaica, Hugh H. Genoways, John W. Bickham, Robert J. Baker, Carleton J. Phillips

University of Nebraska State Museum: Mammalogy Papers

The modern history of Jamaica is entwined with European exploration of the New World beginning with the landing of Columbus at Discovery Bay on May 4, 1494, during his second voyage to the Americas. Since that time the word Jamaica has conjured thoughts of tropical beaches, trade winds, pleasant tropical nights, Spaniards, British navy, Empire, sugar, rum, plantations, slavery, revolt, maroons, pirates, Port Royal, disasters, hurricanes, and in more recent years independence, tourism, Reggae, and welcoming and happy residents. Our knowledge of Jamaican natural history begins with Browne (1789). He and other early naturalists displayed a broad interest in plants …


Mammals Of The Cosigüina Peninsula Of Nicaragua, Hugh H. Genoways, Robert M. Timm Apr 2005

Mammals Of The Cosigüina Peninsula Of Nicaragua, Hugh H. Genoways, Robert M. Timm

University of Nebraska State Museum: Mammalogy Papers

Nicaragua’s Cosigüina Peninsula, located at the northwestern tip of the country, is one of the most poorly studied biotic regions in Central America. The peninsula has been occupied for millennia because the climate of the region supported human habitation and because of its strategic position along the rich Pacific coast. The combination of long-term occupancy by humans and the cataclysmic eruptions of Volcán Cosigüina have produced a heavily impacted landscape. During the 1960s, the University of Kansas conducted multiyear field surveys of the terrestrial mammals on the peninsula and the adjacent mainland to quantify species diversity, relationships, abundances, habitat use, …

Types Of Areas And The Origin Of Black Flies Fauna In Mongolia (Diptera: Simuliidae), Josef Halgoš Jan 2005

Types Of Areas And The Origin Of Black Flies Fauna In Mongolia (Diptera: Simuliidae), Josef Halgoš

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The survey of Mongolian Black Flies species (Diptera: Simuliidae) is given in the presented work. The classification based on Emelyanov (1974) and Gorodkov (1984) appeared to be as most advantageous one. Black Flies species found on the Mongolian territory up to now were classified according to the character of their distribution among 5 groups: Holoarctic species (7 species), Eurasian (15), Eastern Palaearctic (20), Turanian-Mediterranean (7), Mongolian endemic species (8). Individual groups are divided according to the type of area into smaller subgroups. The zoogeographical analysis has shown big similarity with Black Flies zoogeography in Siberia and Far East (in percentage …

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Physocephala pusilla Meigen (Diptera: Conopidae) was found to be a dangerous endoparasitoid of the alfalfa leafcutter bee Megachile rotundata F. (Hymenoptera: Megachilidae) in Mongolia. The conopid fly parasitizes adults and causes their early death. In 1989 and 1990, 16% and 15% respectively of the M. rotundata females were found dead in front of the bee shelter. However, the number of bees (females and males) dying in the field is unknown. These bees cause a contamination of the alfalfa fields due to an increase of the conopid population. Therefore, Ph. pusilla becomes a serious problem for the management of M. rotundata …

A New Species Of The Genus Rhogeessa, With Comments On Geographic Distribution And Speciation In The Genus, Hugh H. Genoways, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

A new species of Rhogeessa is described from southern Suriname. The new species is characterized by a karyotype that possesses a diploid number of 52 and a fundamental number of 52 and by its relatively large overall size compared to other South American Rhogeessa. Tenspecies are now recognized within the genus. Seven of these species, including the one described herein, are members of R. tumida complex. Two of these species--R. io and R. minutilla--also occur in South America and the remaining four species are confined to Mexico and Central America.
