Paoletti, Mattia Beggio, Luca Dorigo, Alberto Pamio, Tiziano Gomiero, Claudio Furlan, Mauro Brilli, Angelo Leandro Dreon, Roberto Bertoni, Andrea Squartini

International Journal of Speleology

The microbial diversity of moonmilk, a hydrated calcium carbonate speleothem, was evaluated from two Italian caves to provide context for the food web of highly-specialized troglobitic beetles, Cansiliella spp. (Leptodirinae), with distinctive carbon and nitrogen isotope values indicative of a novel food source. The moonmilk and associated percolating waters had low to no extractable chlorophyll, with an average organic C:N ratio of 9, indicating limited allochthonous input and a significant contribution from microbial biomass. The biomass from moonmilk was estimated to be ~104 micro- and meiofaunal individuals per m2 and ~107 microbial cells/ml. Betaproteobacteria dominated the …


A Floristic Analysis And Comparison Of Plant Communities In Harlan County, Nebraska, Naomi D. Hastings, Steven J. Rothenberger Jun 2013

A Floristic Analysis And Comparison Of Plant Communities In Harlan County, Nebraska, Naomi D. Hastings, Steven J. Rothenberger

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Historically, the Republican River Valley in Harlan County, Nebraska, has been extensively explored, but the county flora has continually been under-represented and has been found to lack records for plants that are considered common. During the 2009 growing season, a taxonomic study and comparison of 3 different sites in Harlan County was made. Site #1 was pastureland and Sites #2 and #3 were both riparian, located on the north side of the Republican River. Collections were pressed, dried, identified, and deposited in the University of Nebraska at Kearney Herbarium (NEBK). Forty-eight new county records were verified, in­cluding cutleaf-cucumber (Cyclanthera …

Differences In Population Structure Estimated Within Maternally- And Paternally-Inherited Forms Of Mitochondria In Lampsilis Siliquoidea (Bivalvia: Unionidae), Robert A. Krebs, W. Calvin Borden, Na'tasha M. Evans, F. Paul Doerder

Biological, Geological, and Environmental Faculty Publications

Mussels in several orders possess two separate mitochondrial lineages: a standard female-inherited form and one inherited only through males. This system of doubly uniparental inheritance (DUI) for mitochondrial genes provides an opportunity to compare the population structure of gene-lineages passed either mother-to-daughter or father-to-son. In the present study, we contrast variation in the male and female haplotype lineages of the American freshwater mussel species, Lampsilis siliquoidea (sometimes called Lampsilis radiata luteola), throughout the Lake Erie, Ohio River, and upper Mississippi River watersheds, and contrast variation with the sequences obtained for the related species/subspecies Lampsilis radiata radiata from Maine.

Persons As Plants: Ecopsychology And The Return To The Dream Of Nature, Monica Gagliano Mar 2013

Persons As Plants: Ecopsychology And The Return To The Dream Of Nature, Monica Gagliano

Landscapes: the Journal of the International Centre for Landscape and Language

Abstract. In this article, I examine human-plant perceptions and interactions in terms of developing a new perspective on the perception and the actions of people towards plants. By combining my scientific understanding of the biological world and my own experiences working with plant shamans, storytellers and mystics from around the world, I engage with the idea that the hierarchical structure by which Western science defines the variety of life forms as ‘primitive’ or ‘more evolved’ is at the root of the current environmental crisis and I argue that the solution to it rests in a change of this very perspective.

Age Structure Of Moose (Alces Alces) Killed By Gray Wolves (Canis Lupus) In Northeastern Minnesota, 1967–2011, L. David Mech, Michael E. Nelson Jan 2013

Age Structure Of Moose (Alces Alces) Killed By Gray Wolves (Canis Lupus) In Northeastern Minnesota, 1967–2011, L. David Mech, Michael E. Nelson

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The ages of 77 adult Moose (Alces alces) killed by gray Wolves (Canis lupus) during the period 1967–2011 in northeastern Minnesota were significantly older than those of a sample of 17 585 Moose killed by hunters in nearby Ontario. Our findings support those of earlier studies of protected Moose populations in national parks that found that gray Wolves tend to kill disproportionately more older Moose.


Identification Of The Rainbowfish In Lake Eacham Using Dna Sequencing, Culum Brown, Yagiz Aksoy, Hilal Varinli, Michael Gillings Jan 2013

Identification Of The Rainbowfish In Lake Eacham Using Dna Sequencing, Culum Brown, Yagiz Aksoy, Hilal Varinli, Michael Gillings

Veterinary Science and Medicine Collection

The Lake Eacham rainbowfish (Melanotaenia eachamensis) was once thought to be confined to its type locality within the Lake Eacham World Heritage National Park. M. eachamensis disappeared from the lake following the translocation of several species into the lake and the species was pronounced extinct in the wild in 1987. In a 2007 survey we noticed that rainbowfish were present in the lake once again. We used a molecular marker to identify these fish and the likely source population. Analysis of the D-loop region of mitochondrial DNA revealed that the species now present in the lake is Melanotaenia splendida, and …

On The Morphology And Taxonomy Of Griphobilharzia Amoena Platt And Blair, 1991 (Schistosomatoidea), A Dioecious Digenetic Trematode Parasite Of The Freshwater Crocodile, Crocodylus Johnstoni, In Australia [Critical Comment], Thomas R. Platt, Eric P. Hoberg, Leslie A. Chisholm Jan 2013

On The Morphology And Taxonomy Of Griphobilharzia Amoena Platt And Blair, 1991 (Schistosomatoidea), A Dioecious Digenetic Trematode Parasite Of The Freshwater Crocodile, Crocodylus Johnstoni, In Australia [Critical Comment], Thomas R. Platt, Eric P. Hoberg, Leslie A. Chisholm

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Griphobilharzia amoena Platt and Blair, 1991 was originally described was originally described as a dioecious trematode, parasitic in the circulatory system of the Australian freshwater crocodile, Crocodylus johnstoni, with the female completely enclosed in a gynecophoric chamber of the male and the two worms orientated anti-parallel to each other. A recent publication questions the original description, arguing that G. amoena is monoecious and, as a consequence, the species was transferred to Vasotrema Stunkard, 1928 (Spirorchiidae) as Vasotrema amoena n. comb. We provide photomicrographic evidence that the original description of G. amoena is correct and that Griphobilharzia Platt and Blair, …

Twenty-four worms were collected from the bronchioles in both lungs of a male nine-banded armadillo Dasypus novemcinctus Linnaeus, 1758 captured in Teacalco, Morelos, Mexico. The worms, herein named Metathelazia mexicana n. sp., show a constriction in the esophagus at the level of the nerve ring; males of the species have 7 pairs of papillae, fewer than the other species in the genus. Metathelazia capsulata is the most similar species to Metathelazia mexicana; however, the latter has much shorter spicules. This is the fourth species in the genus known to occur in the New World.

Applying The Principles Of Spatial Modelling To The Management Of Biodiversity In The Fragmented Landscapes Of South-Western Australia, Shaun Molloy Jan 2013

Applying The Principles Of Spatial Modelling To The Management Of Biodiversity In The Fragmented Landscapes Of South-Western Australia, Shaun Molloy

Theses: Doctorates and Masters

Biodiversity conservation throughout the world is challenged by the impacts of a changing climate on fragmented landscapes. To mitigate these threats, conservation managers require models which can demonstrate the consequences of both negative impacts and management actions. This need can be addressed through spatial modelling applications. Unfortunately, throughout much of the world, spatial modelling is forgone, being seen as requiring skills and resources beyond the means of many conservation planners and managers. This thesis seeks to address this dilemma by delivering criteria for a successful modelling application and by providing case studies which demonstrate how appropriate modelling can be undertaken …

Developing A Restorable Wetland Index For Rainwater Basin Wetlands In South-Central Nebraska: A Multi-Criteria Spatial Analysis, Zhenghong Tang, Xu Li, Nan Zhao, Ruopu Li, F. Edwin Harvey

Community and Regional Planning Program: Faculty Scholarly and Creative Activity

It is always challenging for decision makers to prioritize wetland conservation programs at the landscape scale. This study employed a GIS-based multi-criteria spatial decision support tool that identified locations with the highest restoration potential for wetland conservation programs in the Rainwater Basin in south-central Nebraska. Five indicators were considered to assess wetland restoration potential: (1) Vegetation characteristics; (2) Soil characteristics; (3) Water volume released from hydrological modification of agricultural irrigation pits; (4) Topographical depression status; and (5) Habitat condition. The results suggested 192 (1.6% of the total) hydric soil footprints as the highest prioritized locations for future wetland restoration programs. …

Climate's Role In Polar Bear Past [Letters], Kurt E. Galbreath, Joseph A. Cook, Eric P. Hoberg Jun 2012

Climate's Role In Polar Bear Past [Letters], Kurt E. Galbreath, Joseph A. Cook, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Striking temporal concordance between the new date for divergence of polar bears and persistent freezing of the Arctic Ocean suggests that this may be one of relatively few instances in which a specific paleoclimatological episode can be convincingly linked to a specific evolutionary event, and it provides vivid demonstration of climatic forcing as a determinant of diversification in biological systems.

Observations Of Oviposition Behavior Among North American Tiger Beetle (Coleoptera: Carabidae: Cicindelinae) Species And Notes On Mass Rearing, Mathew L. Brust, C. Barry Knisley, Stephen M. Spomer, Kentaro Miwa Jan 2012

Observations Of Oviposition Behavior Among North American Tiger Beetle (Coleoptera: Carabidae: Cicindelinae) Species And Notes On Mass Rearing, Mathew L. Brust, C. Barry Knisley, Stephen M. Spomer, Kentaro Miwa

University of Nebraska State Museum: Entomology Papers

Although the larvae of a large number of North American tiger beetle species have been described, little information exists on the oviposition behavior of female tiger beetles at the species level. In this study, we found that the oviposition behavior varied widely among species, with some species utilizing more than one method. We found that, contrary to many references, several tiger beetle species did not oviposit from above the soil surface by inserting the ovipositor into the soil. Instead, several species oviposited by tunneling over 20 mm below the soil surface. In addition, we outline recently used successful protocols for …


Nonlinear Effects Of Group Size On The Success Of Wolves Hunting Elk, Daniel R. Macnulty, Douglas W. Smith, L. David Mech, John A. Vucetich, Craig Packer Jan 2012

Nonlinear Effects Of Group Size On The Success Of Wolves Hunting Elk, Daniel R. Macnulty, Douglas W. Smith, L. David Mech, John A. Vucetich, Craig Packer

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Despite the popular view that social predators live in groups because group hunting facilitates prey capture, the apparent tendency for hunting success to peak at small group sizes suggests that the formation of large groups is unrelated to prey capture. Few empirical studies, however, have tested for nonlinear relationships between hunting success and group size, and none have demonstrated why success trails off after peaking. Here, we use a unique dataset of observations of individually known wolves (Canis lupus) hunting elk (Cervus elaphus) in Yellowstone National Park to show that the relationship between success and group …

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Lymantria dispar L. is one of the most serious forest pests worldwide by infesting large forest areas involving massive tree dieback. Unlike outbreaks of Lymantria dispar L. in Germany that cause massive defoliation, observations of outbreaks of Lymantria dispar asiatica made in the research area Khonin Nuga, West Khentii, Mongolia during the past six years showed only punctual defoliation, and dieback was extremely scarce. However, information on the performance of Lymantria dispar asiatica and the corresponding reaction of host tree species in Khonin Nuga is rare. Therefore, this study concentrates on the examination of primarily affected tree species and the …
