Red Deer Browsing Decelerates Shrub Regrowth Despite Increasing Wolf Presence, F. Riesch, C. Raab, Bettina Tonn, N. Gerber, M. Zetsche, J. Signer, Marcus Meißner, Sven Herzog, Niko Balkenhol, Johannes Isselstein

IGC Proceedings (1997-2023)

Semi-natural open habitats in Europe have been shaped by traditional land use practices, such as extensive mowing or livestock grazing. However, socio-economic transformations have led to the abandonment of many grassland and heathland areas and conservation management is now required to maintain these biodiverse habitats. Grazing by wild red deer (Cervus elaphus) can be a convenient alternative to laborious mechanical management or livestock grazing. Yet it remains unclear if free-ranging ungulates can counteract shrub growth sufficiently to maintain open habitats—especially with natural predators, i.e. wolves (Canis lupus), recolonizing Europe. To assess red deer effects on shrub …

Grazing And Animal Welfare Of Dairy Cows In Europe, What Do We Know?, A. Van Den Pol-Van Dasselaar, D. Hennessy, J. Isselstein

IGC Proceedings (1997-2023)

Grazing systems are important components of the landscape in almost all European countries. Grazing is inherently close to the nature of herbivores, but no longer applied everywhere in Europe. This paper discusses the extent of dairy cow grazing in Europe and the effect of grazing on animal welfare. The study builds on results of surveys from the European Grassland Federation (EGF) Working Group “Grazing” (WGG) in the period 2010–2022 and a focus group meeting in 2022. Data on the extent of grazing of dairy cows in Europe are provided. Europe can be divided into six distinctive regions with respect to …

A Systems Approach To Assessing The Viability Of Grazing Legume Systems Across Europe, C. F. E. Topp, C. J. Smith, L. Wu, G. Molle

IGC Proceedings (1997-2023)

Forage legumes are important in grassland farming throughout much of the world because of their ability to fix atmospheric nitrogen, and hence they are expected to play an increasingly prominent role in low- input grazing farming systems in Europe. Nevertheless, the socio-economic impact of the adoption of the "new" legume based grazing technologies have been poorly researched (Rochon et al., 2004). Thus a methodology has been developed to:

* Assess the on-farm costs and benefits of including different legume crops for animal production;
* Determine the types of management systems and environmental conditions under which forage legumes may play …

Hashes Are Not Suitable To Verify Fixity Of The Public Archived Web, Mohamed Aturban, Martin Klein, Herbert Van De Sompel, Sawood Alam, Michael L. Nelson, Michele C. Weigle

Computer Science Faculty Publications

Web archives, such as the Internet Archive, preserve the web and allow access to prior states of web pages. We implicitly trust their versions of archived pages, but as their role moves from preserving curios of the past to facilitating present day adjudication, we are concerned with verifying the fixity of archived web pages, or mementos, to ensure they have always remained unaltered. A widely used technique in digital preservation to verify the fixity of an archived resource is to periodically compute a cryptographic hash value on a resource and then compare it with a previous hash value. If the …

Biodiversity loss is a major global challenge and minimizing extinction rates is the goal of several multilateral environmental agreements. Policy decisions require comprehensive, spatially explicit information on species’ distributions and threats. We present an analysis of the conservation status of 14,669 European terrestrial, freshwater and marine species (ca. 10% of the continental fauna and flora), including all vertebrates and selected groups of invertebrates and plants. Our results reveal that 19% of European species are threatened with extinction, with higher extinction risks for plants (27%) and invertebrates (24%) compared to vertebrates (18%). These numbers exceed recent IPBES (Intergovernmental Platform on Biodiversity …

Russia, Europe And Central Asia Energy Security And Pipeline Politics, Mehmet Kınacı

Graduate Program in International Studies Theses & Dissertations

Energy Security will continue to remain as one of the top security concerns for Europe. Depleting reserves and growing energy demand have increased European dependence on external energy resources. Today, Russia is by far the largest supplier of oil, coal and the natural gas to Europe. Oil and natural gas revenues have played a vital role to rebound the Russian economy and have supported Putin’s ambitions to reestablish Russia as a great power, increasing its influence over the former Soviet space. This complex energy relationship has increasingly been a cause of concern.

The main question this study seeks to answer …

Challenges Of Pastoralism And Rangelands In Europe, P. Manzano

IGC Proceedings (1997-2023)

High Human Development achievements across Europe explain the situation of pastoralism in the region. While its economic importance has dwindled over the last century in terms of livelihood provision, pastoralism is nonetheless key for supporting rural population - especially in the areas of lower agricultural potential - and for delivering ecosystem services in vast areas. The mainstreaming of scientific research means that pastoralism is increasingly recognized as a sustainable livelihood by the European general public. In spite of this better press, the advanced average age of European pastoralists and the increased gender imbalances pose great sustainability risks in the short- …

Performance Of Endophyte Infected Tall Fescue In Europe And North America, Kari Saikkonen, Timothy D. Phillips, Stanley H. Faeth, Rebecca L. Mcculley, Irma Saloniemi, Marjo Helander

Plant and Soil Sciences Faculty Publications

Human assisted plant invasions from Europe to North America have been more common than the reverse. We tested endophyte-mediated performance of tall fescue in parallel three year experiments in Europe and the USA using endophyte infected and uninfected wild and cultivated plants. Experimental plants were subjected to nutrient and water treatments. Whereas endophyte infection increased tall fescue performance in general, the effects of endophytes on plant growth and reproduction varied among plant origins under different environmental conditions. Naturally endophyte-free Finnish cultivar ‘Retu’ performed equally well as ‘Kentucky-31’ in both geographic locations. All Eurasian origin plants performed well in the US. …

Agenda: Indigenous Water Justice Symposium, University Of Colorado Boulder. Getches-Wilkinson Center For Natural Resources, Energy, And The Environment

Indigenous Water Justice Symposium (June 6)

Indigenous peoples throughout the world face diverse and often formidable challenges of what might be termed “water justice.” On one hand, these challenges involve issues of distributional justice that concern Indigenous communities’ relative abilities to access and use water for self-determined purposes. On the other hand, issues of procedural justice are frequently associated with water allocation and management, encompassing fundamental matters like representation within governance entities and participation in decision-making processes. Yet another realm of water justice in which disputes are commonplace relates to the persistence of, and respect afforded to, Indigenous communities’ cultural traditions and values surrounding water—more specifically, …

Odu-European Collaborations On Climate Change And Sea Level Rise Reserach, Tal Ezer

CCPO Publications

Less than five years ago, Old Dominion University started the Climate Change and Sea Level Rise Initiative (CCSLRI), which led to the recently established Mitigation and Adaptation Research Institute (MARI) and the Hampton Roads Sea Level Rise Preparedness & Resilience Intergovernmental Planning Pilot Project. This interdisciplinary area of research also has a long history in many European countries. Direct measurements of sea level started more than 200 years ago and flood mitigation measures have been in effect for a long time in London, the Netherlands and many other places. Today, reports on flooding in Norfolk, UK, by the BBC or …

Mechanism Design For Near Real-Time Retail Payment And Settlement Systems, Zhiling Guo, Robert John Kauffman, Mei Lin, Dan Ma

Research Collection School Of Computing and Information Systems

have made extensive use of interbank netting systems, in which payments are accumulated for end-of-day settlement. This approach, known as deferred net settlement (DNS), reduces the liquidity needs of a payment system, but bears inherent operational risks. As large dollar volumes of retail payments accumulate swiftly, real-time gross settlement (RTGS) is an attractive option. It permits immediate settlement of transactions during the day, but it brings up other risks that require consideration. We propose a hybrid payment management system involving elements of both DNS and RTGS. We explore several hybrid system mechanism designs to allow payment prioritization, reduce payment delays, …

Reproductive Phase Determination In Male Meagre (Argyrosomus Regius, Sciaenidae): Testis Development And Histologic Corroboration Of A Gross Anatomical Scale, Nuno Prista, Leonel Gordo, José Lino Costa, Maria José Costa, Cynthia Jones

OES Faculty Publications

Reproductive stage determination of male gonads has received sparse attention in fish biology literature with few studies detailing the building of gross anatomical- and histologic scales. The meagre (Argyrosomus regius) is one of the world's largest sciaenids and supports a significant regional fishery in European and North African waters whose reproductive patterns are yet to be fully investigated. In the present study, we derive a macroscopic grading system for meagre testis using semi-quantitative graphs that feature the testis variability along the species size range and time of the year. We then describe the histological stages and reproductive phases of male …

Glacier Slip And Seismicity Induced By Surface Melt, Peter L. Moore, J. Paul Winberry, Neal R. Iverson, Knut A. Christianson, Sridhar Anandakrishnan, Miriam Jackson, Mark E. Mathison, Denis Cohen

All Faculty Scholarship for the College of the Sciences

Many of the key processes governing fast glacier flow involve interaction between a glacier and its basal hydrological system, which is hidden from direct observation. Passive seismic monitoring has shown promise as a tool for remotely monitoring basal processes, but lack of glacier-bed access prevents clear understanding of the relationships between subglacial processes and corresponding seismic emissions. Here we describe direct measurements of basal hydrology, sliding, and broadband seismicity made in a unique subglacial facility in Norway during the onset of two summer melt seasons. In the most pronounced of these episodes, rapid delivery of surface meltwater to the bed …

We present the results of total column measurements of CO, C₂H₆ and fine-mode aerosol optical depth (AOD) during the "Quantifying the impact of BOReal forest fires on Tropospheric oxidants over the Atlantic using Aircraft and Satellites" (BORTAS-B) campaign over eastern Canada. Ground-based observations, using Fourier transform spectrometers (FTSs) and sun photometers, were carried out in July and August 2011. These measurements were taken in Halifax, Nova Scotia, which is an ideal location to monitor the outflow of boreal fires from North America, and also in Toronto, Ontario. Measurements of fine-mode AOD enhancements were …

Analysis - Toward A New American Military., Adam Lowther, Jan Kallberg

Jan Kallberg

In releasing the United States Department of Defense’s (DoD) Sustaining U.S. Global Leadership: Priorities for 21st Century Defense and Defense Budget Priorities and Choices in January 2012, President Barack Obama and Secretary of Defense Leon Panetta offered a rationale for the administration’s reductions in defense spending. By stating that the shift in strategic direction is an effort to “put our fiscal house in order” and a response to the 2011 Budget Control Act, which requires DoD to reduce spending by $487 billion between fiscal years 2012 and 2021, the United States’ NATO partners in Europe were given considerable reason for …

Palaeoclimatic Significance Of Perennial Ice Accumulations In Caves: An Example From Scarisoara Ice Cave, Romania, Aurel Persoiu Tiritu

USF Tampa Graduate Theses and Dissertations

Stable isotopes in ice cores drilled in the polar and high-mountain region have been used intensively to reconstruct past climatic changes and atmospheric dynamics. However, no similar studies have been conducted on perennial ice accumulations in caves due to a limited understanding of the links between the external and cave environments, and the way in which the climatic signal can be recorded by the cave ice.

In this thesis, we successfully designed and build a research methodology for the reconstruction of past climatic changes based on perennial ice accumulation in caves, using as example the Scarisoara Ice Cave, Romania. The …
