University of Nebraska State Museum: Mammalogy Papers
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 ( …

Celastrina Serotina (Lycaenidae: Polyommatinae): A New Butterfly Species From The Northeastern United States And Eastern Canada, Harry Pavulaan, David M. Wright
The Taxonomic Report of the International Lepidoptera Survey
A new light-venter Azure species, Celastrina serotina, is described from the northeastern United States and eastern Canada. The flight period of this univoltine spring species is interpolated (allochrony) between its sympatric congeners, C. lucia Auctorum (not Kirby) and C. neglecta (Edwards). In this regard it is similar to C. neglectamajor Opler & Krizek in the southern Appalachians and C. idella Wright & Pavulaan on the New Jersey coastal plain. In a significant portion of its range, C. serotina larvae feed on eriophyid mite-formed galls on the upper surface of Black Cherry Prunus serotina Ehrh. …

Biodemography Of A Long-Lived Tephritid: Reproduction And Longevity In A Large Cohort Of Female Mexican Fruit Flies, Anastrepha Ludens, James R. Carey, Pablo Liedo, Hans-Georg Müller, Jane-Ling Wang, Damla Senturke, Lawrence G. Harshman
Lawrence G. Harshman Publications
Age of sexual maturity, daily and lifetime reproductive rates, and life span were recorded in a laboratory cohort of Mexican fruit flies consisting of over 1100 females maintained individually. The results revealed that, relative to the medfly, the Mexfly is slower maturing (14 vs 17 days), more fecund (1400 vs 650–1100 eggs/female), and longer lived (50 vs 35 days). The results reinforced the generality of several earlier findings on the medfly including the deceleration of mortality at older ages and the weakness of the correlation between the rate of egg laying at early ages and both subsequent reproduction and remaining …

The Symmetry Of Longevity, Lawrence G. Harshman, Hans-Georg Müller, Xueli Liu, Yue Wang, James R. Carey
Lawrence G. Harshman Publications
We tested the hypothesis that relatively symmetrical flies live longer. Vein measurements on the left and right wings from the same individual were used to characterize bilateral symmetry in relationship to age-specific survival in defined cohorts. A longitudinal cohort study supported the hypothesis of a correlation between bilateral symmetry and longevity. For another type of experiment, wings were removed from females and males at approximately the beginning of adult life. Thus, there would be no effect of wings per se on adult survival. These wings were measured to characterize bilateral asymmetry, and the day of death of each dewinged individual …

Guide To Nebraska’S Wetlands And Their Conservation Needs: Second Edition, 2005, Ted Lagrange
Nebraska Game and Parks Commission: Publications
Wetlands — a source of great interest, and at times conflict. Wetlands represent different things to different people. At times they’re viewed as shallow, muddy nuisances while at other times they’re viewed as wonderful, varied and productive assets. This is because wetlands take on many roles as part of a complex and dynamic system. Understanding wetlands and wetland issues requires understanding the complex and varying roles that wetlands can play. To aid in this understanding, this guide defines wetlands, discusses their importance and dynamics, identifies threats and losses, describes conservation programs, and takes an in-depth look at Nebraska’s regional wetland …

Differences In Pah Tolerance Between Capitella Species: Underlying Biochemical Mechanisms, Lis Bach, Annemette Palmqvist, Lene Juel Rasmussen, Valery E. Forbes
Differences In Pah Tolerance Between Capitella Species: Underlying Biochemical Mechanisms, Lis Bach, Annemette Palmqvist, Lene Juel Rasmussen, Valery E. Forbes
Valery Forbes Publications
The polychaete Capitella capitata consists of a species complex within which differences in tolerance to toxicants have been observed. For example, it has been shown that Capitella sp. S is more sensitive (e.g., in terms of survival, growth and reproduction) to PAH and other stressors than the more opportunistic Capitella sp. I, which is able to take up and biotransform the PAH fluoranthene (Flu). In the present study, an investigation was performed to examine whether differences in tolerance between Capitella species sp. I and sp. S are due to differences in biotransformation, measured as the amount of Flu-metabolites produced by …
Xenophilic Mating Preferences Among Populations Of The Jumping Spider Habronattus Pugillis Griswold, Eileen Hebets, Wayne P. Maddison
Xenophilic Mating Preferences Among Populations Of The Jumping Spider Habronattus Pugillis Griswold, Eileen Hebets, Wayne P. Maddison
Eileen Hebets Publications
Sexual selection is thought to have driven the diversification of courtship behavior and associated ornamentation between geographically isolated populations of the jumping spider Habronattus pugillis Griswold. In an attempt to understand the pathways of sexual selection during this diversification, we conducted reciprocal mating trials between two populations of H. pugillis (Santa Rita [SR] and Atascosa [AT]) that differ in both male courtship display and secondary sexual ornamentation. Observations of mating frequencies show a xenophilic mating preference in which SR females have a stronger response to AT males than to SR males, while AT females show no difference in mating frequency. …

Ecology Of The Missouri River: Missouri River Creel Survey, Bellevue Bridge To Camp Creek, 3 April Through 29 May 2004, Gerald Mestl
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
The Nebraska Game and Parks Commission's strategic plan has stated the following management goal for the Missouri River: Restore, protect, and maintain the diversity of historic Missouri River habitats, resources, and ecosystem functions in order that present and future generations may enjoy consumptive and non-consumptive outdoor recreational opportunities (NGPC 1996). To accomplish this goal the Nebraska Game and Parks Commission identified the following five objectives: • To restore terrestrial and aquatic floodplain habitat types by 2008. This would include old oxbows, chutes, side channels, sand bars, backwaters, wetlands, and other shallow water habitats. To restore ftows that reflect the natural …
Taxonomic Analysis Of The Genus Megisto (Satyridae) In The Eastern United States, Part I: Types, Type Localities, And Taxonomic Relationships Of The Available Names, Ronald R. Gatrelle
Taxonomic Analysis Of The Genus Megisto (Satyridae) In The Eastern United States, Part I: Types, Type Localities, And Taxonomic Relationships Of The Available Names, Ronald R. Gatrelle
The Taxonomic Report of the International Lepidoptera Survey
The genus Megisto Hübner, 1819 in the eastern United States and southeastern Canada is currently comprised of the original epithets Papilio eurytus Fabricius, 1775, Papilio cymela Cramer, 1777, Papilio eurytris, Fabricius, 1793, and Neonympha eurytris viola Maynard, 1891. Because the eastern Megisto is considered by some, including the present author, to contain two or more sibling species, the types and type localities of each of these names were studied. Where no type was found and no type locality fixed, typification was established by lectotypification or neotypification and a type locality was fixed. The taxonomic relationship of these taxa were …

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 …

The Prairie Naturalist
We conducted surveys of thistle-feeding insects on Canada thistle [Cirsium arvense (L.) Scop.] during the 2000 and 2001 growing seasons at Lacreek National Wildlife Refuge (LNWR), South Dakota, and analyzed their impact on thistle seed production, germination, and viability. Insects included Canada thistle stem weevil [Hadroplontus litura, formerly Ceurtorhynchus lilura, (Coleoptera: Curculionidae)], introduced at LNWR as a biocontrol agent, plus two seed head parasites, the thistle head weevil [Rhinocyllus conicus (Coleoptera: Curculionidae)] and the seed head fly [Terellia ruficauda (Diptera: Tephritidae)]. Infestation by these insects caused no significant reduction in per-head seed yield, with means ranging from 82.5 seeds per …
Biological Notes On Ground-Nesting Digger Wasps From Western Nebraska, Robert W. Matthews, Janice R. Matthews
Biological Notes On Ground-Nesting Digger Wasps From Western Nebraska, Robert W. Matthews, Janice R. Matthews
The Prairie Naturalist
Nine species of sphecid wasps nesting in sparsely vegetated sandy soils near Ogallala, Keith County, Nebraska were studied during June 2003. The first records of the nest and prey of Cerceris clypeata gnarina Banks and Tachysphex williamsi R. Bohart are presented. Two species of weevils, Baris striata Say and B. subsimilis Casey, were prey of C. clypeata gnarina, with 12 to 22 individuals stocked per cell. Because B. subsimilis is a biological control agent for thistle, this finding is a caution to researchers not to ignore the potential impact of predatory wasps on the community. The single nest of T …

Grazing Intensity Effects On Northern Plains Mixed-Grass Prairie, Wendi M. Rogers, Donald R. Kirby, Paul E. Nyren, Bob D. Patton, Edward S. Dekeyser
The Prairie Naturalist
We evaluated the effects of long-term (1988 to 2000) grazing on northern mixed-grass prairie at tI.e Central Grasslands Research Extension Center in south-central North Dakota. We did not detect a difference in herbaceous basal cover between grazing intensities following 12 consecutive years of season-long moderate (50% removal of annual above-ground standing crop) and heavy (80% removal of annual above-ground standing crop) grazing. However, both moderate and heavy grazing intensities reduced above-ground herbaceous standing crop, total root biomass, and soil organic carbon. Moderate grazing intensity maintained a greater amount of deep (10 to 20 cm) and total root biomass relative to …
Christmas Bird Counts For North Dakota 2004, Robert N. Randall
Christmas Bird Counts For North Dakota 2004, Robert N. Randall
The Prairie Naturalist
Christmas Bird Counts were made in 21 areas in North Dakota again in the year 2004. During the year a new count site was established in Pembina County and registered with the Audubon Society but an actual count was not made in the area this year. The location of the all areas in which counts were actually made is shown in Fig. 1. A relatively mild fall season leading up to the count period left much more open water than normal. Weather conditions during the count period varied widely with some areas reporting temperatures in the 40's and 50's of, …
Attention-Altering Signal Interactions In The Multimodal Courtship Display Of The Wolf Spider Schizocosa Uetzi, Eileen Hebets
Attention-Altering Signal Interactions In The Multimodal Courtship Display Of The Wolf Spider Schizocosa Uetzi, Eileen Hebets
Eileen Hebets Publications
Complex signals are common throughout the animal kingdom, consisting of one or more signals in one or more sensory modalities presented within a single display. I tested an efficacy-based backup hypothesis of complex signal function using the bimodal courtship signaling wolf spider Schizocosa uetzi. This hypothesis predicts that the visual and vibratory courtship displays function as backups to each other in the presence of environmental variability. I compared mating frequencies across four environmental treatments in which the visual and vibratory environments were manipulated independently in a 2 × 2 design with visual treatments of light/dark (i.e., visual signal present/absent) …

An Additional Record Of The Ornate Box Turtle From Western South Dakota, Steven G. Platt, Jennifer I. Stover, Edward J. Stover Iii
The Prairie Naturalist
On 11 June 2003, one of us (EJS) found an ornate box turtle crossing BIA Highway 2, approximately 7.2 km north of Sharps Comer on the Pine Ridge Indian Reservation in Shannon County, South Dakota. The air temperature at the time of collection was approximately 30°C, and the substrate was moist from light rain the previous day. The turtle was an adult female with a straight-line carapace length of 118 mm. Other straight-line measurements were: maximum carapace width = 100 mm; plastron length = 122 mm; maximum plastron width = 82 mm; and maximum shell depth = 64 mm. We …
K-Means Clustering With Multiresolution Peak Detection, Guanshan Yu, Leen-Kiat Soh, Alan B. Bond
K-Means Clustering With Multiresolution Peak Detection, Guanshan Yu, Leen-Kiat Soh, Alan B. Bond
Avian Cognition Papers
Clustering is a practical data mining approach of pattern detection. Because of the sensitivity of initial conditions, k-means clustering often suffers from low clustering performance. We present a procedure to refine initial conditions of k-means clustering by analyzing density distributions of a data set before estimating the number of clusters k necessary for the data set, as well as the positions of the initial centroids of the clusters. We demonstrate that this approach indeed improves the accuracy and performance of k-means clustering measured by average intra to interclustering error ratio. This method is applied to the virtual ecology project to …

On October 22, 2002, 5000 six-page surveys (Appendix 3) were sent to a stratified-random sample of Nebraska anglers drawn from the 2001 licensed anglers database. The database included all anglers who purchased a fishing license in 2001 as well as all lifetime fishing permit holders who purchased their license before or during 2001. The database did not include those possessing a free permit, such as veteran’s or senior citizen permits. The survey subsample (2.6% of the 2001-licensed angler database) was stratified such that the proportions of surveys in the subsample (4366 residents and 634 non-residents) matched the proportions of resident/non-resident …

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, …

Availability Of Suitable Habitat For Northern River Otters In South Dakota, Alyssa M. Kiesow, Charles D. Dieter
Great Plains Research: A Journal of Natural and Social Sciences
Currently, the northern river otter (Lontra canadensis) is listed as a threatened species in South Dakota. We determined whether adequate habitat was available for reintroducing river otters in South Dakota. The 17 rivers/creeks included in the analysis were selected according to stream size, water gradient, and water permanence. A vegetation transect was conducted and a water sample was collected at each study site, ranging from one to four per river. Rivers/creeks were rated (1 = least suitable to 5 = most suitable) according to habitat requirements of river otters in the following categories: stream characteristics, watershed features, water …

Seismic Signals Are Crucial For Male Mating Success In A Visual Specialist Jumping Spider (Araneae: Salticidae), Damian O. Elias, Eileen Hebets, Ronald R. Hoy, Andrew C. Mason
Eileen Hebets Publications
The diversity of courtship displays throughout the animal kingdom is immense and displays can range from seemingly simple, to incredibly complex. Signalers often possess elaborate morphological adaptations for signals directed at a specific sensory modality in receivers. In some cases, these signals are so compelling to human observers, the possibility that important signals exist in other sensory modalities is ignored, potentially resulting in an incomplete characterization of the communication system. Jumping spiders (Salticidae) have remarkable visual capabilities. Yet one species, Habronattus dossenus, has recently been shown to have a complex repertoire of multicomponent seismic courtship signals in addition to …

Analyses in this report will refer to number of different groups. Catfish seeking anglers are defined as any angler who has spend at least 1 trip during 2002 in pursuit of a catfish species (channel, blue, flathead, or bullhead). This is the most general group included in the analyses and is also the least avid group of anglers in regards to their relationship to catfish angling. Catfish anglers are defined as those respondents who identified a catfish species as the species they most prefer to target. Catfish anglers represent a smaller group of respondents with a higher avidity for catfish …
