Abstract:
Abstract Grazing by large herbivores may negatively affect bird populations. This is of great conservation concern in areas with intensive sheep grazing. Sheep management varies substantially between regions, but no study has been performed in less intensively grazed systems. In a fully replicated, landscape scale experiment with three levels of sheep grazing, we tested whether the abundance and diversity of an assemblage of mountain birds were negatively affected by grazing or if grazing facilitated the bird assemblage. Density of birds was higher at high sheep density compared with low sheep

Abstract:
Domestic cats (Felis catus) are ubiquitous predators of birds in urban areas. In addition to the lethal effect of predation, there can also be sublethal, negative effects of domestic cats on individual birds. These effects have led to the inference that reducing outdoor cat densities would benefit urban bird communities. Here we estimate the likely result of policies/programs designed to reduce densities of owned outdoor cats in urban areas, estimating relationships between bird richness/abundance and cat densities across 58 landscapes in Ottawa, Ontario, Canada.

Grazing by large herbivores is increasingly used as a management tool in European nature reserves. The aim is usually to support an open but heterogeneous habitat and its corresponding plant and animal communities. Previous studies showed that birds may profit from grazing but that the effect varies among bird species. Such studies often compared bird counts among grazed areas with different stocking rates of herbivores. Here, we investigated how space use of Konik horses and Highland cattle is related to bird counts in a recently restored conservation area with a year-round natural grazing ma

Urbanization contributes to the loss of the world's biodiversity and the homogenization of its biota. However, comparative studies of urban biodiversity leading to robust generalities of the status and drivers of biodiversity in cities at the global scale are lacking. Here, we compiled the largest global dataset to date of two diverse taxa in cities: birds (54 cities) and plants (110 cities). We found that the majority of urban bird and plant species are native in the world's cities. Few plants and birds are cosmopolitan, the most common being Columba livia and Poa annua .

Surface mining often changes the native landscape and vegetation of an area. Reclamation is used to counter this change, with the goal of restoring the land to its original pre-mined state. The process of reclamation creates early successional-stage lands, such as grasslands, shrublands, and wetlands, attracting new plant and animal species to the area.

Abstract:
Before the financial crash froze the motion of money, the plan to repopulate thinned-out downtowns had become an article of faith among advocates of low-carbon urbanism. Where else could the blueprint for truly sustainable living be realized? The technical difficulty and cost of retrofitting suburbs for higher density was prohibitive, even in the postwar inner-ring subdivisions that were more compact in their land use than today’s sprawl counterparts on the urban fringe. It was in city centers that the biggest improvements in energy efficiencies and emissions could be achieved, and, since the carbon clock was ticking, there was a consensus that their repopulation by middle-class residents ought to be accomplished posthaste. Urbanists, guided unerringly by Jane Jacobs’s prescriptions for vibrant street life, had long argued that the kind of society fostered by mixed-use and mixed-income downtown neighborhoods was more open-minded and mutually gratifying than the atomized lifestyle of the master-planned exurban community. After all, Jacobs’s version of the city had been driven primarily by concerns about quality of life, or what could be called cultural health. In her view, those who had planned the urban renewal projects of the 1950s and 1960s and hastened the population flight outwards had bequeathed a soulless, antiurban city—“a Great Blight of Dullness,” as she memorably put it. Hence, her full-throated praise for the daily festival of street life in mixed-use neighborhoods, even those condemned by the improvers as examples of urban blight. Compared to the presumed conformity of the suburbs, the humming, cosmopolitan milieu of her downtown sidewalks surely boasted a superior civilization. In the decades after Jacobs launched her downtown revolution, the argument for high-density core residence got a turbo boost from environmentalist quarters. Criticism of suburbia was no longer a matter of taste—how ugly and dull are these cookie-cutter houses and strip malls? Now it was backed up by estimates of the ecological costs of the unplanned, low-density tract development known as sprawl. In recent years, climate change had lent an extra sense of urgency to the case for downtown resettlement.

Abstract:
Why did I choose to end this book with the Gila River Indian Community’s effort to win back its water? Because it is a parable about how democracy and its courts can not only serve but also be served by the quest for sustainability. The GRIC water settlement brought a long struggle for environmental justice to a triumphant conclusion. Delivering justice meant that a large portion of the region’s available resources would be sequestered from the growth machine. Instead of supplying a new generation of low-density tract housing, the water could now be used to produce healthy, local food for the area population, and, if nonindustrial agriculture prevailed, the result would be a double win for carbon reduction. Surely, this is how a green polity ought to act, redressing the claims of those who have been aggrieved, and doing it in a way that extends long-term benefits for all. If all responses to environmental injustice were able to follow suit, it would be a welcome model for moving forward. Even if the Gila River example is unlikely to be replicated in other places, its guiding spirit is a sound one. What if the key to sustainability lies in innovating healthy pathways out of poverty for populations at risk, rather than marketing green gizmos to those who already have many options to choose from? These are not mutually exclusive options, of course, but the lessons I took away from my research convinced me of the pressing need for clear alternatives to the eco-apartheid syndrome that afflicts Phoenix and so many other cities. Building a low-carbon economy by targeting only the LOHAS demographic (Lifestyles of Health and Sustainability, the upmarket segment of 40 million, or 20 percent of consumers, nationally) will end up doing little more than adding a green gloss to patterns of chronic inequality. Likewise, placing all of our faith in clean-tech fixes will cede too much decision making to a closed circle of experts who, regardless of their technical prowess, will have no power to prevent the uneven application of their solutions.

Abstract:
West Nile Virus is a vector-borne flavivirus that affects mainly birds, horses, and humans. The disease emerged in the United States in 1999 and by 2001 had reached Michigan. In clinical human cases, the most common symptoms are fever, weakness, nausea, headache, and changes in mental state. The crow is the most common wildlife host in the life cycle of the virus. The state of Michigan, through the Michigan Department of Community Health, collected the spatial locations of over 8,000 dead birds (Corvidae), statewide, during 2002. The large number of samples made spatial and temporal hotspot detection possible. However, the volunteer reporting method produced a dataset with a direct correlation between the numbers and locations of the dead birds and human population density and accurately identifying hotspots remains a challenge. Geographic variation in dead bird intensity was modeled using both global and local spatial clustering algorithms. Statistical models identified overall spatial structure and local clustering. Identification of hotspots was confounded by limited information about the collection procedures, data availability and quality, and the limitations of each method.

Abstract:
Climate change is likely to impact all trophic levels, although the response of communities and ecosystems to it has only recently received considerable attention. Further, it is expected to affect the magnitude of species interactions themselves. In this chapter, we summarize why and how climate change could affect predator–prey interactions, then review the literature about its impact on predator–prey relationships in birds, and provide prospects for future studies. Expected effects on prey or predators may include changes in the following: distribution, phenology, population density, behaviour, morphology, or physiology. We review the currently available information concerning particular key topics: top-down versus bottom-up control, specialist versus generalist predators, functional versus numerical responses, trophic cascades and regime shifts, and lastly adaptation and selection. Finally, we focus our review on two well-studied bird examples: seabirds and raptors. Key future topics include long-term studies, modelling and experimental studies, evolutionary questions, and conservation issues.

Abstract:
Climate variation strongly influences fluctuations in size of avian populations. In this chapter, we show that it is difficult to predict how the abundance of birds will respond to climate change. A major reason for this is that most available time series of fluctuations in population size are in a statistical sense short, thus often resulting in large uncertainties in parameter estimates. We therefore argue that reliable population predictions must be based on models that capture how climate change will affect vital rates as well as including other processes (e.g. density-dependences) known to affect the population dynamics of the species in question. Our survey of examples of such forecast studies show that reliable predictions necessarily contain a high level of uncertainty. A major reason for this is that avian population dynamics are strongly influenced by environmental stochasticity, which is for most species, irrespective of their life history, the most important driver of fluctuations in population size. Credible population predictions must therefore assess the effects of such uncertainties as well as biases in population estimates.

Abstract:
A current project is underway to create a prototype of an anatomically correct seagull with biologically accurate flight kinematics. The presented work is focused on the computational fluid dynamics (CFD) analysis of bird flight kinematics. A finite volume approach, using Fluent, was used to attempt to model the kinematics of bird flight with varying degrees of freedom to analyze the lift, drag, pressure, and vortices magnitude associated with a range of flight kinematics. Dimensional analysis has been performed to analyze the effects of angle of incidence on the different sections of a seagul

Abstract:
In this work, a set of operators for a Particle Swarm (PS) based optimization algorithm is investigated for the purpose of finding optimal values for some of the classical benchmark problems. Particle swarm algorithms are implemented as mathematical operators inspired by the social behaviors of bird flocks and fish schools. In addition, particle swarm algorithms utilize a small number of relatively uncomplicated rules in response to complex behaviors, such that they are computationally inexpensive in terms of memory requirements and processing time. In particle swarm algorithms, particles in a

Abstract:
The vibration of the towed seismic cable (streamer) is the main reason for the efficiency reduction of the seismic survey. In this paper, a vibration suppression scheme of the streamer in the seismic survey is investigated. The system model includes a hyperbolic partial differential equation with variable coefficient describing the seismic cable, and an ordinary differential equation describing the dynamic of the birds. Exact model knowledge and adaptive controllers, based on the Lyapunov method, are designed to suppress the vibration of streamer caused by the course deviations of the towing v

Abstract:
Humic acid substances (HAs) in natural soil and sediment environments effect the retention and degradation of insensitive munitions compounds and legacy high explosives (MCs): DNAN, DNi- NH4+, nMNA, NQ, NTO (neutral and anionic forms), TNT, and RDX.A humic acid model compound has been considered using molecular dynamics, thermodynamic integration, and density functional theory to characterize the munition binding ability, ionization potential, and electron affinity compared to that in the water solution. Humic acids bind most compounds and act as both a sink and source for electrons. Ionizatio
