Jaguars And Pumas Exhibit Distinct Spatiotemporal Responses To Human Disturbances In Colombia’S Most Imperiled Ecoregion, Joe J. Figel, Sebastián Botero-Cañola, Juan David Sánchez-Londoño, Javier Racero-Casarrubia

University of Nebraska State Museum: Mammalogy Papers

Abstract

Coexistence of sympatric felids is facilitated by mutual avoidance and the partitioning of habitats, prey, and time. Anthropogenic disturbances disrupt this coexistence in fragmented landscapes, potentially triggering cascading influences in ecological communities. We used photographic data from 8,717 trap nights (November 2014–June 2016) at 87 camera trap sites in Colombia’s middle Magdalena River basin to compare spatiotemporal overlap among jaguars (Panthera onca), pumas (Puma concolor), their prey, and humans, at sites of high and low disturbance, as determined by the human influence index. Human disturbance events (e.g. domestic dogs, livestock, and humans, including armed hunters) …

Predictors Of Bat Species Richness Within The Islands Of The Caribbean Basin, Justin D. Hoffman, Gabrielle Kadlubar, Scott C. Pedersen, Roxanne J. Larsen, Peter A. Larsen, Carleton J. Phillips, Gary G. Kwiecinski, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Several mechanisms have been shown to influence species richness among island ecosystems, yet most studies limit their focus to a few predictor variables. The objective of this study is to investigate variation in Chiropteran richness across islands in the Caribbean Basin with an extensive set of predictor variables. Using recent faunal surveys, the most contemporary list of bat species per island was complied. Data were collected on 17 predictor variables, which summarized five general island characteristics including island area, isolation, habitat diversity, human impact, and climate. An information-theoretic approach was used by fitting alternative candidate models to determine which variable(s) …

The Neotropical Variegated Squirrel, Sciurus Variegatoides (Rodentia: Sciuridae) In Nicaragua, With The Description Of A New Subspecies, Hugh H. Genoways, Robert M. Timm

University of Nebraska State Museum: Mammalogy Papers

The Neotropical variegated squirrel, Sciurus variegatoides, is represented in Nicaragua by five known subspecies—adolphei, belti, boothiae, dorsalis, and underwoodi. Analyses of morphometrics, color, and color patterns of 394 specimens from throughout the country and all available literature support the retention of these subspecies, but also reveal the presence of a sixth population of these squirrels, which is worthy of description and recognition as a new subspecies. This new subspecies is confined to Isla de Ometepe in Lago de Nicaragua. Variegated squirrels on Ometepe are on average the smallest variegated squirrels in the country …

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

University of Nebraska State Museum: Mammalogy Papers

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 …

Bats Of Sint Eustatius, Caribbean Netherlands, Scott C. Pedersen, Peter A. Larsen, Sil A. Westra, Ellen Van Norren, Wesley Overman, Gary G. Kwiecinski, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

The bat fauna of the Caribbean island of Sint Eustatius consists of five documented species—Monophyllus plethodon, Brachyphylla cavernarum, Artibeus jamaicensis, Ardops nichollsi, and Molossus molossus—and one provisional species—Tadarida brasiliensis. The Insular Single-leaf Bat, M. plethodon, is reported in the scientific literature for the first time from Sint Eustatius based on material presented herein. The bat fauna of the island is considered to be unbalanced because only three species, which are the environmental generalists, are abundant, whereas the more specialized species are rare or absent from the fauna. It is our hypothesis …

Science At Engineer Cantonment, Hugh H. Genoways, Brett C. Ratcliffe, Carl R. Falk, Thomas E. Labedz, Paul R. Picha, John R. Bozell

University of Nebraska State Museum: Mammalogy Papers

Conclusions

It is our contention that Thomas Say, Titian Peale, Edwin James, and their colleagues of the Stephen Long Expedition of 1819–1820 were heavily engaged in scientific research, which took the form of the first biodiversity inventory undertaken in the United States. This accomplishment has been overlooked both by biologists and historians, but it should rank among the most significant accomplishments of the expedition. The results of this inventory continue to inform us today about environmental, faunal, and floral changes along the Missouri River in an area that is known to be an ecotone between the deciduous forests of the …

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 …

Addendum To Encomia And Reflections, Clyde Jones (1935-2015): Encomium, Robert J. Baker, Carleton J. Phillips, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

This is the authors' collective attempt to provide an encomium (an honest song of praise) for Clyde Jones. After some urging from the editors of this volume, the authors conspired to share some memories of Clyde.

Editors’ note: Due to various factors, this encomium was submitted too late to be included in the published memorial volume. However, in consideration of the relationship of the authors to Clyde Jones, we agreed to make this encomium available via electronic format as a supplement to the printed volume.

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 generated and …

Bats Of The Grenadine Islands, West Indies, And Placement Of Koopman's Line, Hugh H. Genoways, Gary G. Kwiecinski, Peter A. Larsen, Scott C. Pedersen, Roxanne J. Larsen, Justin D. Hoffman, Mark De Silva, Carleton J. Phillips, Robert J. Baker

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. …

Recent Occurrence Of An American Black Bear In Nebraska, Justin D. Hoffman, Sam Wilson, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

We report on a young male, cinnamon-phase American black bear (Ursus americanus) that was collected in northwestern Nebraska on May 12, 2008. This specimen represents the first black bear taken in Nebraska since 1907. Cranial characteristics and mass of the individual indicated a 15–16-month old bear. This bear may have dispersed from the Laramie Mountains in southeastern Wyoming along the North Platte River into western Nebraska. This record adds to the growing number of cases where large carnivores are reinvading previously occupied territory in the Great Plains. These reinvasions potentially have broad ecological implications to local prey populations …

Phylogenetics And Phylogeography Of The Artibeus Jamaicensis Complex Based On Cytochrome-B Dna Sequences, Peter A. Larsen, Steven R. Hoofer, Matthew C. Bozeman, Scott C. Pedersen, Hugh H. Genoways, Carleton J. Phillips, Dorothy E. Pumo, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

The phylogenetics and phylogeography of the Jamaican fruit-eating bat (Artibeus jamaicensis) were examined based on analysis of DNA sequence variation in the mitochondrial cytochrome-b gene for 176 individuals representing all 13 subspecies of A. jamaicensis (sensu Simmons 2005). Results document that A. jamaicensis (sensu Simmons 2005) comprises 3 monophyletic assemblages that are separated phylogenetically by the presence of A. obscurus, A. lituratus, and . amplus. According to the mitochondrial DNA sequence variation, A. jamaicensis, A. schwartzi, and A. planirostris are appropriate species-level names for these lineages. Haplotypes identifiable as A. jamaicensis were absent east …

An inventory of mammals in the vicinity of Brownsberg Nature Park, Suriname, incorporated a number of different sampling methods including examining museum voucher specimens, an animal-rescue operation, transect surveys, camera photo-traps, and interviews with local inhabitants. We document a total of 125 mammal species present in the Park. These include ten opossums, five pilosans, four armadillos, 58 bats, eight monkeys, 13 carnivores, one tapir, four artiodactyls, and 22 rodents. Nine of these species are reported for the first time from Suriname: one mouse opossum (Marmosops pinheiroi); one naked-backed moustached bat (Pteronotus gymnonotus); four fruit-eating bats ( …

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

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, …

University of Nebraska State Museum: Mammalogy Papers

Seventeen specimens of the rare Yucatán vesper mouse, Otonyctomys hatti, are now known from Belize, Guatemala, and the Mexican states of Campeche, Quintana Roo, and Yucatán. We herein report a second specimen of O. hatti, from Belize, extending the known geographic range of the species 95 km to the southeast in the country. This is the first location at which O. hatti has been taken sympatrically with the Central American vesper mouse, Nyctomys sumichrasti. We also report data on three additional specimens of O. hatti from Campeche. Nyctomys and Otonyctomys share similar habits and habitat requirements, and …

Historical Biogeography Of The Woodchuck (Marmota Monax Bunkeri) In Nebraska And Northern Kansas, Zachary P. Roehrs, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Discusses the historical biogeography of the Woodchuck (Marmota monax bunkeri) in Nebraska and northern Kansas.

First paragraph:

Jones et al. described the western limit of Marmota monax in the United States as the eastern edge of the northern Great Plains in Oklahoma, Kansas, Nebraska, and the Dakotas. Mengel introduced the idea of the Great Plains grasslands as a barrier to contact between birds of eastern and western North American forests. In his studies of bird biogeography on the Platte River, Knopf reported that this barrier has eroded with development of riparian forests along river courses of the Great …

Bats Of Nevis, Northern Lesser Antilles, Scott C. Pedersen, Hugh H. Genoways, Matthew N. Morton, James W. Johnson, Siân E. Courts

University of Nebraska State Museum: Mammalogy Papers

Only one species of bat, Molossus molossus, previously has been documented as occurring on the northern Lesser Antillean island of Nevis. Field research and reviews of existing museum collections have provided documentation based on voucher specimens for an additional seven species occurring on the island — Noctilio leporinus, Brachyphylla cavernarum, Monophyllus plethodon, Ardops nichollsi, Artibeus jamaicensis, Natalus stramineus, and Tadarida brasiliensis. The biological diversity of the chiropteran fauna on Nevis is similar to that found on other islands in the northern Lesser Antilles. Ecologically, this is a simple chiropteran fauna, including one …

During the last Ice Age, Grenada and the …

Natural History Of The Southern Short-Tailed Shrew, Blarina Carolinensis, Hugh H. Genoways, Jerry R. Choate

University of Nebraska State Museum: Mammalogy Papers

The southern short-tailed shrew, Blarina carolinensis, inhabits a broad range of ecological situations in the southeastern United States and, in many areas, is among the two or three most abundant species of small mammals. Nevertheless, its natural history is poorly known and much of what researchers assumed was fairly well understood about this species actually resulted from work on another species (Blarina brevicauda) and may not be correct in all instances. This problem resulted when modem systematic methods revealed that the wide-ranging and well-studied species known at that time as Blarina brevicauda actually consisted of three species …

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.

The Bats Of Fountain Cavern, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

First paragraph:

During May 1988, two species of bats--Brachyphylla cavernarum (Antillean cave bat) and Natalus stramineus (funnel-eared bat)--were captured at the opening of Fountain Cavern. Only Brachyphylla cavernarum was captured inside of the cave. The weather was extremely wet during our visit to Anguilla so our work in Fountain Cavern was limited by hazardous conditions. Nevertheless, we did make a thorough survey of the bats inside the cave. There is only one other species on Anguilla--Monophyllus redmani (Antillean long-tongued bat)--that might be expected to utilize Fountain Cavern as a roosting site.

Includes the author's recommendations about conservation for …

Caribbean Island Zoogeography: A New Approach Using Mitochondrial Dna To Study Neotropical Bats, Carleton J. Phillips, Dorothy E. Pumo, Hugh H. Genoways, Phillip E. Ray

University of Nebraska State Museum: Mammalogy Papers

Genetic analysis of animal mitochondrial DNA is a new and valuable addition to the battery of techniques available to zoogeographers. This paper describes characteristics of mitochondrial DNA (mtDNA) that make it applicable for the study of island zoogeography.

Some traditional zoogeographic questions are examined using mtDNA from the Neotropical fruit bat, Artibeus jamaicensis. The specific questions are: 1) To what extent are island populations isolated (that is, does interbreeding occur between the insular subspecies)? 2) Can a single founding female account for the mitochondrial genomes on specific islands in the Antilles? 3) Is there a correlation between the genomic …
