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 Long Shadow Of Senescence: Age Impacts Survival And Territory Defense In Loons, Walter H. Piper, Kristin M. Brunk, Joel A. Flory, Michael W. Meyer

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Senescence, increased mortality that occurs among animals of advanced age, impacts behavior and ecology in many avian species. We investigated actuarial, reproductive, and behavioral senescence using capture, marking, and resighting data from a 26-year study of common loons (Gavia immer). Territorial residents of both sexes exhibited high annual survival (0.94) until their mid 20s, at which point survival fell to 0.76 and 0.77 in males and females, respectively. Sexual symmetry in actuarial senescence is somewhat surprising in this species, because males make a substantially greater investment in territory defense and chick-rearing and because males engage in lethal contests for territory …

2016 Christmas Bird Counts, Don Paseka

Nebraska Bird Review

Fourteen Nebraska counts were held during the 2016 CBC season, which is one less than last year. The Harrison and Crawford counts were cancelled this year, but in the opposite corner of the state, a new count was started that includes Indian Cave State Park. An unusually mild November and a seasonable start to December were followed by a modest cold snap during the second week of the month. The Harlan County count was run early in the period on the 15th with ample open water, and it produced a record number of species (90) for that circle. But in …

Winter Field Report, December 2016 To February 2017, W. Ross Silcock

Nebraska Bird Review

This was an interesting winter from several standpoints. The trend of unexpected winter occurrences and earlier arrivals in “spring” continued. Mid-winter records of several species were notable: Rock Wren, Marsh Wren, American Pipit, Pine Warbler, and Chipping Sparrow. Rarities (see below) that could be considered in this category as well were Golden-crowned Sparrow and Lesser Goldfinch. For earlier arrivals, there was a noticeable influx 14-18 Feb of various species that provided rather early dates for those species. In this group were Blue-winged Teal, Ruddy Duck, Double-crested Cormorant, American White Pelican, and Turkey Vulture.

Some amazing numbers were reported, including a …

Brambling In Bellevue, Sarpy County, Loren Padelford, Babs Padelford

Nebraska Bird Review

As we were having breakfast on January 8, 2017, we spotted an unusuallooking bird with House Sparrows in the tree above our deck. After consulting the National Geographic field guide, we determined it was a Brambling. Soon it was feeding on the deck where we were able to get some photos. It was first spotted at 9:25 a.m. and again at 10:30. We put the information on NEBirds and by late morning birders began to arrive.The first group saw the bird at 12:02. By early afternoon we had standing room only in our family room. The bird appeared again at …

Homestead National Monument Of America, Bat Acoustic Monitoring, September 2016, Daniel S. Licht

United States National Park Service: Publications

Abstract

Homestead National Monument of America is a 211-acre park located in an agrarian landscape in southeastern Nebraska. From September 16 to October 1, 2016, park staff deployed acoustic monitors at three sites in the park for purposes of monitoring night-time bat activity. The three sites averaged 179, 48, and 33 bat detections per night. Night-time bat activity was generally highest in the 1-2 hours following sunset.

Based on the acoustic surveys the big brown (Eptesicus fuscus), eastern red (Lasiurus borealis), northern long-eared (Myotis septentrionalis) and evening bats (Nycticeius humeralis) were present at the …

Plasma Metabolites Reveal Changes In Physiological State Of Eared Grebes (Podiceps Nigricollis) During Three Non-Migratory Periods, Allison A. Yoshida

Theses

Energy storage and use during the annual cycle of migratory birds is dynamic especially during migration. However, considerable amounts of the annual cycle are spent not migrating, and the physiological state of birds during these non-migratory periods is not well understood. We compared plasma metabolites (TRIG, BUTY, URIC, GLY) in Eared Grebes (Podiceps nigricollis) residing at three important areas when they are not migrating: fall staging (postbreeding at Mono Lake, California), spring staging (pre-breeding at Great Salt Lake, Utah), and an extended stopover prior to spring staging (Salton Sea, California). Plasma metabolites were also measured in resting and active grebes …

Serradigitus Miscionei, The First Vaejovid Scorpion To Exhibit Parthenogenesis, Richard F. Ayrey

Euscorpius

Thelytokous parthenogenesis (all-female broods) is strongly suggested for the vaejovid species Serradigitus miscionei (Vaejovidae) from southern Arizona, USA. This conclusion is based on the examination of 187 specimens and 15 broods, all determined as females.

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.

Gait Changes In A Line Of Mice Artificially Selected For Longer Limbs, Leah M. Sparrow, Emily Pellattt, Sabrina S. Yu, David A. Raichlen, Herman Pontzer, Campbell Rolian

Publications and Research

In legged terrestrial locomotion, the duration of stance phase, i.e., when limbs are in contact with the substrate, is positively correlated with limb length, and negatively correlated with the metabolic cost of transport. These relationships are well documented at the interspecific level, across a broad range of body sizes and travel speeds. However, such relationships are harder to evaluate within species (i.e., where natural selection operates), largely for practical reasons, including low population variance in limb length, and the presence of confounding factors such as body mass, or training. Here, we compared spatiotemporal kinematics of gait in Longshanks, a long-legged …

Rapid Increase In Genetic Diversity In An Endemic Patagonian Tuco-Tuco Following A Recent Volcanic Eruption, Jeremy L. Hsu, Sharon Kam, Mauro N. Tammone, Eileen A. Lacey, Elizabeth A. Hadly

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Catastrophic natural events can have profound impacts on patterns of genetic diversity. Due to the typically unpredictable nature of such phenomena, however, few studies have been able to directly compare patterns of diversity before and after natural catastrophic events. Here, we examine the impacts of a recent volcanic eruption in southern Chile on genetic variation in the colonial tuco-tuco (Ctenomys sociabilis), a subterranean species of rodent endemic to the area most affected by the June 2011 eruption of the Puyehue-Cordón Caulle volcanic complex. To provide a comparative context for interpreting changes in genetic variation in this species, we …

Molecular And Morphological Data Reveal Three New Cryptic Species Of Chiasmocleis (Mehely 1904) (Anura, Microhylidae) Endemic To The Atlantic Forest, Brazil, Mauricio C. Forlani, João F. R. Tonini, Carlos A. G. Cruz, Hussam Zaher, Rafael O. De Sá

Biology Faculty Publications

Three new cryptic species of Chiasmocleis from the Atlantic Forest of Brazil are described. Two of these species occur in the northeastern states of Sergipe and Bahia, whereas the third species is found in the southeastern state of São Paulo. The new species can be distinguished from other congeneric species by the molecular data, as evidenced in the phylogeny, and by a combination of morphological characters including: size, foot webbing, dermal spines, and coloration patterns. Chiasmocleis species differ in osteological traits, therefore we also provide an osteological description of each new species and comparisons with data reported for other species …

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.

We provide a checklist of 41 valid species and their synonyms of Pandinus sensu lato. We revise Horn of Africa genera Pandiborellius stat. n. and Pandinurus; all …

Habitat Selection By The Northern Long-Eared Myotis (Myotis Septentrionalis) In The Midwestern United States: Life In A Shredded Farmscape, Jeremy A. White, Patricia Freeman, Cliff A. Lemen

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Populations of the Northern Long-Eared Myotis (Myotis septentrionalis) have declined dramatically in recent years in eastern North America due to white-nose syndrome. Although M. septentrionalis was once common in parts of eastern North America, few studies have examined habitat selection of this species in an agricultural landscape. We used acoustical methods to quantify bat activity and construct a habitat model of M. septentrionalis in an intensively farmed area in the Midwestern United States, where mortality from white-nose syndrome has not yet been observed. Our study confirms that M. septentrionalis prefers forest and avoids open habitats in this agricultural …

A New Species Of The “Apacheanus” Group Of Genus Pseudouroctonus From Western Texas (Scorpiones: Vaejovidae), Richard F. Ayrey, Michael E. Soleglad

Euscorpius

A new species of the “apacheanus” group of genus Pseudouroctonus is described from western Texas, USA, Pseudouroctonus brysoni, sp. nov. This new species is closely related to P. apacheanus (Gertsch et Soleglad, 1972) and two other species recently described from southern Arizona. A combination of morphological differences in the hemispermatophore, the mating plug, and several morphometric-based characters are identified as diagnostic.
