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. …

Seagrass–Pathogen Interactions: ‘Pseudo-Induction’ Of Turtlegrass Phenolics Near Wasting Disease Lesions, Latina Steele, Melanie Caldwell, Anne Boettcher, Tom Arnold

Biology Faculty Publications

Marine protists of the genus Labyrinthula cause the seagrass wasting disease, which is associated with regional die-offs of eelgrass Zostera marina and also infects turtlegrass Thalassia testudinum . The ability of seagrasses to resist pathogen attack is determined by multiple factors, which are poorly understood. One factor hypothesized to influence seagrass disease resistance is the presence of (poly)phenolic natural products such as caffeic acid, which inhibits the growth of L. zosterae in in vitro laboratory bioassays. This hypothesis has been supported by reports of pathogen-induced phenolic accumulations in eelgrass Z. marina. To test the response of T. testudinum to …

The SRG met on Tuesday 1 February 2005 at the Fremantle Sailing Club, and this document is the official report from that meeting.

Development Of Biological Reference Conditions Of Wadeable Streams In The Major Ecoregions And Subecoregions Of Georgia, Duncan L. Hughes

Theses and Dissertations

One bioassessment tool available to resource managers to indicate NPS impairment of wadeable streams and rivers are multi-metric invertebrate indices. Such indices are assembled from metrics in broad categories that represent different aspects of community structure and function (e.g. richness, composition, tolerance/intolerance, feeding group, and habit). Indices must incorporate suites of metrics that are ecologically relevant, quantifiable, non-redundant, and that best individually discriminate between reference sites and impaired sites. More than 240 wadeable streams in Georgia were sampled during the September thru February index period using RBP protocols during three successive sample seasons (1999-2003). Ecoregional reference (minimally impaired) sites, as …

Impact Of Bythotrephes Invasion On Zooplankton Communities In Acid-Damaged And Recovered Lakes On The Boreal Shield, Angela L. Strecker, Shelley E. Arnott

Environmental Science and Management Faculty Publications and Presentations

Invasive species introductions into freshwater ecosystems have had a multitude of effects on aquatic communities. Few studies, however, have directly compared the impact of an invader on communities with contrasting structure. Historically high levels and subsequent reductions of acid deposition have produced landscapes of lakes of varying acidity and zooplankton communitystructure. We conducted a 30-day enclosure experiment in Killarney Provincial Park, Ontario, Canada, to test the effects ofBythotrephes longimanus, an invasive invertebrate predator, on two contrasting zooplankton communities at different stages of recovery from acidification: recovered and acid damaged. Bythotrephes significantly decreased zooplankton biomass and abundance in both communities but …

Fisheries Occasional Publication No. 32 - Allocation Of The Western Australian Abalone Resource Between User Groups, Department Of Fisheries Western Australia

Fisheries Occasional Publications

In this submission to the Integrated Fisheries Allocation Advisory Committee (IFAAC), the Department will outline what it believes are the most practical and cost effective ways of managing a system for allocating the abalone resource between the commercial, customary and recreational sectors.

In preparing this submission, it has been noted that because of the limited data on recreational catch outside of the metropolitan area, the Sustainable Harvest Limit (SHL) set for the fishery relates only to the area that is equivalent to Area 7 of the commercial fishery. Further, it is acknowledged that the Minister has approved that proportional catch …

A Phylogenetic Analysis Of Vanzolinius Heyer, 1974 (Amphibia, Anura, Leptodactylidae): Taxonomic And Life History Implications, Rafael O. De Sá, W. Ronald Heyer, Arley Camargo

Biology Faculty Publications

The validity of the monotypic leptodactylid frog genus Vanzolinius Heyer, 1974 has been questioned recently. We explore the relationship of Vanzolinius discodactylus within the cluster of closely related genera Adenomera, Leptodacylus, and Lithodytes with both morphological and molecular data sets. Morphological and combined morphological and molecular data were analyzed using maximum parsimony; molecular data sets were analyzed with maximum likelihood methods. The resultant relationships are unambiguous in Vanzolinius being imbedded within Leptodactylus. In order to maintain Leptodactylus as a monophyletic genus, Vanzolinius is placed in the synonymy of Leptodactylus Fitzinger, 1826. The implications of relationships analyzed in …

Redescripción De La Morfología Larval Externa De Dos Especies Del Grupo De Leptodactylus Fuscus (Anura, Leptodactylidae), José A. Langone, Rafael O. De Sá

Biology Faculty Publications

Re-description of the larval external morphology of two species of the Leptodactylus fuscus group (Anura, Leptodactylidae). The larvae of Leptodactylus gracilis (D’Orbigny y Bibron, 1840) and L. mystacinus Bumeister, 1861 are re-described and compared with previous descriptions noting intraspecific variation in oral disc characteristics (arrangement of papillae and rows of cornified teeth). The external morphological analysis of larvae of the Leptodactylus fuscus group suggest that the lack of comparable descriptions among species, as well as the lack of analyses of their intraspecific variation, limits the use of larval characteristics for diagnostic purposes.

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

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 …

Executive Summary

Macrobenthic communities of the Elizabeth River watershed have been quantitatively sampled since summer 1999. This report presents the data from the sixth year of sampling in 2004. The three objectives of the Benthic Biological Monitoring Program of the Elizabeth River watershed are: (1) To characterize the health of the tidal waters of the Elizabeth River watershed as indicated by the structure of the benthic communities. ( 2) To conduct trend analyses on long-term data at 14 fixed-point stations to relate temporal trends in the benthic communities to changes in water and/or sediment quality. Trend analyses will be updated …

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 …

"Sibling Species, Advertisement Calls, And Reproductive Isolation In Frogs Of The Leptodactylus Pentadactylus Species Cluster (Amphibia, Leptodactylidae), W. Ronald Heyer, Rafael O. De Sá, A. Rettig

Biology Faculty Publications

A recent re-evaluation of morphological and advertisement call variation in the large species of frogs of the Leptodactylus pentadactylus cluster discovered more examples of sibling species as defined by Ernst Mayr in his influential book Animal Species and Evolution. All previously documented instances of sibling species in frogs demonstrated advertisement call differentiation consistent with the calls serving as pre-mating isolating mechanisms. However, we find one instance of two species with nondistinguishable adult morphologies as well as nondistinguishable advertisement calls. Presumably, the new instances of sibling species reflect retention of ancestral adult morphologies and advertisement calls. Larval and habitat differentiation appear …

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 …

Wireless Sensory Networks For Ecology, John Porter, Peter Arzberger, Hans-Werner Braun, Todd Hansen, Pablo Bryant, Sedra Shapiro, Stuart Gage, Paul Hanson, Timothy Kratz, Chau-Chin Lin, Fang-Pang Lin, William Michener, Thomas Williams

Long Term Ecological Research Network

Field biologists and ecologists are starting to open new avenues of inquiry at greater spatial and temporal resolution, allowing them to "observe the unobservable" through the use of wireless sensor networks. Sensor networks facilitate the collection of diverse types of data (from temperature to imagery and sound) at frequent intervals--even multiple times per second--over large areas, allowing ecologists and field biologists to engage in intensive and expansive sampling and to unobtrusively collect new types of data. Moreover, real-time data flows allow researchers to react rapidly to events, thus extending the laboratory to the field. We review some existing uses of …

Interannual Variation Of Stratification In Lower Chesapeake Bay, Christopher S. Katzenmiller

OES Theses and Dissertations

Stratification in the water column can prove to be an important indicator to the state of the water column and ecosystem. The focus of this research is to evaluate trends in stratification in the Lower Chesapeake Bay. Detailed analysis was performed on a 14 year data set to study interannual variation in the region of study. Potential energy anomaly was used to quantify stratification. Potential energy anomaly is the amount of energy required to mix a water column. It is determined from the vertical density structure of density. Potential energy anomaly is the departure of potential energy from climate conditions. …

Fisheries Occasional Publication No.21 - Allocation Of The Western Rock Lobster Resource Between User Groups, Department Of Fisheries Western Australia

Fisheries Occasional Publications

In this submission to IFAAC, the Department will outline what it believes are the most practical and cost effective ways of managing a system of allocation amongst the commercial, customary and recreational sectors. This recommendation recognises that cost efficiencies and outcomes will be greatly affected by the type of allocation model that is chosen. Consequently the Department recommends that the allocation system should be based on a single allocation to each sector that is available over the entire fishery.

The Department does not recommend having any finer scale zoning of the allocations, or the creation of exclusive recreational fishing areas. …

Side-By-Side Comparison Of Young Grab And Composite Petite Ponar Grab Samples For The Calculation Of The Benthic Index Of Biological Integrity(B-Ibi), Daniel M. Dauer, Michael F. Lane

Benthic Applications

(First paragraph) The Virginia Department of Environmental Quality (DEQ) intends to unite elements of its National Coastal Assessment Program (NCA) with its Chesapeake Bay Probabilistic Benthic Monitoring (CBP-PBM) Program beginning in the summer of 2005. The primary motivations for this decision were two-fold. First, the probable reduction of federal grant support for the NCA Program after the summer of 2004 would require considerable restructuring of the of DEQ’s estuarine probabilistic monitoring to continue with a comprehensive program in the future. Second, the current CBP-PBM Program has not provided sufficient data for the assessment of minor tidal tributary segments using the …

Recruitment In Degraded Marine Habitats: A Spatially Explicit, Individual-Based Model For Spiny Lobster, Mark J. Butler Iv, Thomas W. Dolan Iii, John H. Hunt, Kenneth A. Rose, William F. Herrnkind

Biological Sciences Faculty Publications

Coastal habitats that serve as nursery grounds for numerous marine species are badly degraded, yet the traditional means of modeling populations of exploited marine species handle spatiotemporal changes in habitat characteristics and life history dynamics poorly, if at all. To explore how nursery habitat degradation impacts recruitment of a mobile, benthic species, we developed a spatially explicit, individual-based model that describes the recruitment of Caribbean spiny lobster (Panulirus argus) in the Florida Keys, where a cascade of environmental disturbances has reconfigured nursery habitat structure. In recent years, the region has experienced a series of linked perturbations, among them, seagrass die-offs, …

Range Expansion By Moose Into Coastal Temperate Rainforests Of British Columbia, Canada, C. T. Darimont, P. C. Paquet, T. E. Reimchen, V. Crichton

Biogeography and Ecological Opportunity Collection

Ranges of species are dynamic and respond to long-term climate change and contemporary effects such as habitat modification. We report here that moose (Alces alces) have recently colonized coastal temperate rainforests of British Columbia, Canada. Contrary to recent publications, field observations of moose and their sign, combined with their occurrence in wolf (Canis lupus) faeces, suggest that moose are now widespread on the coastal mainland and occur on least three islands. Traditional ecological knowledge (information accumulated by aboriginal peoples about their environment) suggests that colonization occurred during the mid 1900s, concomitant with logging of major watersheds that bisect the Coast …

A Comparison Of Population Sizes And Number Of Captures For The Desert Woodrat (Neotoma Lepida) In Two Microhabitats In The Las Vegas Wash, Nevada, Jayson Barangan

UNLV Theses, Dissertations, Professional Papers, and Capstones

Planned removal and eradication of saltcedar in the Las Vegas Wash, Nevada could potentially generate adverse impacts on present desert woodrat (Neotoma lepida) populations inhabiting the area. Consequently, research was conducted investigating population sizes of N. lepida in two distinct microhabitat types, saltcedar (Tamarix sp.) and mesquite/quailbush (Prosopis sp./Atriplex lentiformis). The results of this study will aid in gauging the effects of the changes in vegetation once restoration work is completed and assist with logistical scheduling for implementation of control measures. Mark-recapture field techniques were utilized for data collection from July 2002 to June 2003. Population estimates were calculated using …
