Plant Controls Of Terrestrial Trace Gas Fluxes: Legumes, Microbes, Co And Hydrogen, Gary M. King

University of Maine Office of Research Administration: Grant Reports

This research seeks to determine the role of plant-microbe interactions on the production and fate of key trace gases in the atmosphere, particularly carbon monoxide (CO) and hydrogen (H2). Recent observations have revealed that the roots of all plants produce CO, and that the roots of nitrogen-fixing plants (Fabacae, commonly legumes) produce large amounts of both CO and H2. Production of these gases provides the basis for an interaction of plant roots with soil microbes that oxidize CO and H2. Field and greenhouse studies will involve a variety of cultivated and non-cultivated legumes and other plant taxa. Experimental analyses will …

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 …

Proposals For Community Discussion : A Quality Future For The Recreational Marron Fishery : A Five-Year Draft Strategy To Ensure The Long-Term Sustainability Of The Marron Fishery, Recreational Freshwater Fisheries Stakeholder Sub-Committee

Fisheries management papers

While some of the factors threatening the future of the marron fishery can be managed via traditional fisheries controls, many fall outside of the Department of Fisheries’ jurisdiction and require a ‘whole of Government’ approach to management. To help ensure a quality future for the recreational marron fishery, the Recreational Freshwater Fisheries Stakeholder Sub-committee (RFFSS) has now developed a set of draft management proposals designed to form the basis of a five-year management plan for the fishery.

A Five Year Management Strategy For Recreational Fishing On The South Coast. The Minister For Fisheries' Decision In Response To The Final Report Of The South Coast Recreational Fishing Working Group., Jon Ford (Minister For Fisheries; The Kimberley, Pilbara And Gascoyne)

Fisheries management papers

After careful consideration of the South Coast Recreational Fishing Working Group’s recommendations and the wide range of issues raised in submissions, I have made my decisions in respect to the future management arrangements for recreational fishing in South Coast Region. I believe the new management arrangements which will be implemented in 1 January 2006 will go a long way to protecting recreational fishing quality and meeting the long term needs for the sustainable management of recreational fishing. I did note that some of the most pressing concerns raised during public meetings, and in submissions, related to the interaction between the …

A New Species Of Bufo (Anura Bufonidae) From Andean Peru, Edgar Lehr, Jennifer Pramuk, Mikael Lundberg

Edgar Lehr

A new species of Bufo tentatively assigned to the Bulo veraguensis group is described from forests near Paucartambo de Pasco, Peru, at elevations of 2600-3000 m in the Cordillera Oriental of central Peru. The new species differs from all known bufonids by having numerous large glands with many keratinous tips on the dorsum, large glands on the tibia and forearm, and two large dorsal glands lying between the parotoids. The new species is most similar to Bufa chavin. Both species are compared to each other and B. veraguensis with respect to external characters and skull osteology. The tadpole and call …

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. …

Acupuncture Use For Pain As Compared To Other Complementary And Alternative Medicine And Conventional Medicine, Elizabeth Susan Mcgrady

Doctoral Dissertations

The purpose of the study was to determine the factors associated with the use of acupuncture for pain and to compare these factors to the use of other complementary and alternative medicine (CAM) and conventional medical services. The treatment of pain is expensive. In addition, use of surgery and medication increases risk of medical errors, complications, side effects and addiction. Clinical trials of acupuncture for pain have demonstrated results at least as effective as conventional treatments with negligible side effects and complications. Only 4% of the United States population has used acupuncture. The healthcare field is studying means to predict …

Nonindigenous Herpetofauna Of Florida: Patterns Of Richness And Case Studies Of The Impacts Of The Tadpoles Of Two Invasive Amphibians, Osteopilus Septentrionalis And Bufo Marinus, Kevin G. Smith

Doctoral Dissertations

Although invasive species are considered to be a significant threat to native biodiversity, the impacts of very few nonindigenous species are well known. In this dissertation I describe the results of several studies evaluating the impacts of the presence of nonindigenous amphibians and reptiles in Florida. I conducted an analysis to assess the patterns and effects on biodiversity of the establishment of nonindigenous amphibians and reptiles in Florida at the county level. The richness of the 40 established nonindigenous amphibians and reptiles is not distributed evenly across the state, but instead is significantly greater in the southern part of the …

"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 …

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 …

Implications Of Spatial Autocorrelation And Dispersal For The Modeling Of Species Distributions, Volker Bahn

Electronic Theses and Dissertations

Modeling the geographical distributions of wildlife species is important for ecology and conservation biology. Spatial autocorrelation in species distributions poses a problem for distribution modeling because it invalidates the assumption of independence among sample locations. I explored the prevalence and causes of spatial autocorrelation in data from the Breeding Bird Survey, covering the conterminous United States, using Regression Trees, Conditional Autoregressive Regressions (CAR), and the partitioning of variance. I also constructed a simulation model to investigate dispersal as a process contributing to spatial autocorrelation, and attempted to verify the connection between dispersal and spatial autocorrelation in species' distributions in empirical …

Barriers And Flow As Limiting Factors In The Spread Of An Invasive Crayfish (Procambarus Clarkii) In Southern California Streams, Jacob Kerby, Seth Riley, Lee Kats, Paul Wilson

Lee Kats

Invasive crayfish are a major threat to stream ecosystems, yet research has seldom identified successful ways of preventing their spread. Thirty-two stream sections were surveyed during 2000 and 2001 in the Santa Monica Mountains of southern California to determine the distribution of the invasive crayfish Procambarus clarkii. Streams with large barriers (waterfalls, culverts) often did not have crayfish present upstream of barriers. A mark-recapture study indicated that P. clarkii moved both up and downstream between pools, but that barriers significantly reduced movement between pools. Seasonal high flow velocities likely increase passive movement downstream and reduce movement upstream. Results indicate that …

The Reef Fish Assemblage Of The Outer Los Angeles Federal Breakwater, 2002–2003, John Froeschke, Larry Allen, Daniel Pondella

Daniel Pondella

The conspicuous and cryptic fish assemblage of the Los Angeles Federal Breakwater was assessed from 2002 to 2003. Thirty-five species were observed or collected during the study period. The assemblage of cryptic fishes was composed primarily of a mix of Oregonian and San Diegan, species including snubnose sculpin (Orthonopias triacis), coralline sculpin (Artedius corallinus) and blackeye goby (Rhinogobiops nicholsii). The species composition of conspicuous fishes was approximately equal between taxa from these two provinces. Blacksmith (Chromis punctipinnis), black perch (Embiotoca jacksoni) and kelp bass (Paralabrax clathratus) dominated the assemblage of conspicuous fishes. Species composition reflects the localized cool temperature regime …

Three New Species Of Phyrnopus From Central Peru (Amphibia Anura: Leptodactylidae), Edgar Lehr, Mikael Lundberg, Cesar Aguilar

Edgar Lehr

Three new species of Phrynopus (Anura: Leptodactylidae) are described from cloud forest and puna habitats in central Peruvian Departamento de Pasco between 3600 and 4390 m elevation, the latter is the highest known elevation of the genus. The new species have first finger shorter than second, vomerine teeth absent, and tympanic membrane and tympanic annulus absent, but differ in snout-vent length, skin texture, and coloration. Currently 37 species of Phrynopus are described, 26 (70.3%) of which are endemic to Peru.

Species Limits Within The Mexican Garter Snakes Of The Thamnophis Godmani Complex, Douglas A. Rossman, Frank T. Burbrink

Occasional Papers of the Museum of Natural Science, Louisiana State University

The highly variable Thamniphis godmani complex of southern Mexico, comprised of four apparently allopatric populations, was examined by using 28 morphological characters scored on 214 specimens. Character values were tested with univariate and multivariate statistics to determine if populations are morphologically distinct. The results suggest that the four populations represent independently evolving lineages. Four species, three previously undescribed, are recognized in the T. godmani complex. A lectotype is designated for T. godmani. For each species, a diagnosis description of holotype or lectotype, summary of interspecific variation, and statement of distribution are provided. Comparisons are made with T. errans, alleged to …

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 …

Origin Of The Eumetazoa: Testing Ecological Predictions Of Molecular Clocks Against The Proterozoic Fossil Record, Kevin J. Peterson, Nicholas J. Butterfield

Dartmouth Scholarship

Molecular clocks have the potential to shed light on the timing of early metazoan divergences, but differing algorithms and calibration points yield conspicuously discordant results. We argue here that competing molecular clock hypotheses should be testable in the fossil record, on the principle that fundamentally new grades of animal organization will have ecosystem-wide impacts. Using a set of seven nuclear-encoded protein sequences, we demonstrate the paraphyly of Porifera and calculate sponge/eumetazoan and cnidarian/bilaterian divergence times by using both distance [minimum evolution (ME)] and maximum likelihood (ML) molecular clocks; ME brackets the appearance of Eumetazoa between 634 and 604 Ma, whereas …

Asymmetrical Competition And Patterns Of Abundance Of Aedes Albopictus And Culex Pipiens (Diptera : Culicidae), Katie S. Costanzo, Kimberly Mormann, Steven A. Juliano

Faculty Publications – Biological Sciences

We tested for competitive advantage among larvae of Aedes albopictus (Skuse) and Culex pipiens L. in a laboratory experiment and determined the frequency and spatial and temporal patterns of co-occurrence in the field in East St. Louis, IL. In a laboratory competition experiment at multiple combined densities of Ae. albopictus and Cx. pipiens larvae, Ae. albopictus survivorship, and developmental times were significantly affected by conspecific densities but not by Cx. pipiens densities. In contrast, Cx. pipiens survivorship, and developmental times were significantly affected by both conspecific and Ae. albopictus densities. Per capita rate of increase (r') for Ae. albopictus cohorts …

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 …
