    Contributor(s):: Thomas France, Jack Tuholske

    The 1973 passage of the Endangered Species Act (ESA) stands as a landmark event in the evolution of wildlife law in the United States. While earlier statutes such as the National Environmental Policy Act (NEPA) and the Fish and Wildlife Coordination Act required the...

  4. Condensed tannins reduce browsing and increase grazing time of free-ranging goats in semi-arid savannas

    Contributor(s):: Mkhize, N. R., Heitkonig, I. M. A., Scogings, P. F., Dziba, L. E., Prins, H. H. T., Boer, W. F. de

    Tannin concentrations fluctuate spatially and temporally within and among plant species, with consequences for forage quality of herbivores. The extent to which these fluctuations influence foraging activities of goats is not fully understood. While accounting for the effects of the time of the...

  5. Explaining prehistoric variation in the abundance of large prey: a zooarchaeological analysis of deer and rabbit hunting along the Pecho Coast of Central California

    Contributor(s):: Brian F. Codding, Judith F. Porcasi, Terry L. Jones

    Three main hypotheses are commonly employed to explain diachronic variation in the relative abundance of remains of large terrestrial herbivores: (1) large prey populations decline as a function of anthro pogenic overexploitation; (2) large prey tends to increase as a result of increasing social...

  6. The Role of Modern Zoos in Wildlife Conservation: From the WCS to the Wild

    Contributor(s):: John Scott

    The reality of the modern world is that humanity is increasing its population rapidly, and demanding more resources than the earth can provide. Humans are utilizing resources like water and fossil fuels, and are in turn polluting and causing a shift in the global climate. Most importantly, humans...

    Contributor(s):: Anguita, P. M. de, Martin, M. A., Clare, A.

    This article describes and proposes the "environmental subsidiarity principle" as a guiding ethical value in forestry governance. Different trends in environmental management such as local participation, decentralization or global governance have emerged in the last two decades at the global,...

  10. Feral cat management: Perceptions and preferences (A case study)

    Contributor(s):: Wilken, Rachel L. M.

    Feral cat management is a highly debated topic. Trap, Neuter, and Return (TNR) programs have become increasingly popular as an alternative to eradication. Public preference about how to manage feral cats has been explored by previous authors, but no consensus has been reached. Public policy and...

  11. Environmental ethics beyond principle? The case for a pragmatic contextualism

    Contributor(s):: Minteer, B. A., Corley, E. A., Manning, R. E.

    Many non-anthropocentric environmental ethicists subscribe to a "principle-ist" approach to moral argument, whereby specific natural resource and environmental policy judgments are deduced from the prior articulation of a general moral principle. More often than not, this principle is one...

  12. Ethical considerations in agro-biodiversity research, collecting, and use

    Contributor(s):: Engels, J. M. M., Dempewolf, H., Henson-Apollonio, V.

    Humans have always played a crucial role in the evolutionary dynamics of agricultural biodiversity and thus there is a strong relationship between these resources and human cultures. These agricultural resources have long been treated as a global public good, and constitute the livelihoods of...

  13. Local perception of environmental change in a semi-arid area of northeast Brazil: a new approach for the use of participatory methods at the level of family units

    Contributor(s):: Sieber, S. S., Medeiros, P. M., Albuquerque, U. P.

    The diversity of plant resources in the Brazilian semi-arid region is being compromised by practices related to agriculture, pastures, and forest harvesting, especially in areas containing Caatinga vegetation (xeric shrublands and thorn forests). The impact of these practices constitutes a series...

    Contributor(s):: Jonge, B. de

    "Fair and equitable benefit-sharing" is one of the objectives of the UN Convention on Biological Diversity and the FAO International Treaty on Plant Genetic Resources for Food and Agriculture.

    Contributor(s):: Haworth, L., Brunk, C., Jennex, D., Arai, S.

    The idea of agroecosystem health is understood from two perspectives: a system-functions perspective and system-goals perspective. The system functions are: integrity, resilience and efficiency and are essential to the flourishing of a biotic community. The system goals are social, natural and...

    Contributor(s):: Pimentel, D., Shanks, R. E., Rylander, J. C.

    Worldwide, approximately 95 million metric tons of fishery products are harvested from marine and freshwater habitats. A major problem in fisheries around the world is the bioethics of overfishing. A wide range of management techniques exists for fishery, managers and policy-makers to improve...

  19. Biofuels: efficiency, ethics, and limits to human appropriation of ecosystem services

    Contributor(s):: Gomiero, T., Paoletti, M. G., Pimentel, D.

    Biofuels have lately been indicated as a promising source of cheap and sustainable energy. In this paper we argue that some important ethical and environmental issues have also to be addressed: (1) the conflict between biofuels production and global food security, particularly in developing...

  20. Environmental and social implications of waste in US agriculture and food sectors

    Contributor(s):: Pimentel, D.

    A preliminary survey of the environmental and social costs in the US agricultural and food sectors indicates an estimated waste of at least $150 000 million per year of the total $700 000 million food/fibre GNP. Much of the wastes and many of the negative environmental and social impacts...
