    Wilderness Watch, Inc. v. U.S. Fish & Wildlife Service

    The Wilderness Act generally prohibits the development of all structures within wilderness areas. The U.S. Fish and Wildlife Service built two water tanks for bighorn sheep residing in the especially arid Kofa Wilderness region of southwest Arizona. The Ninth Circuit analyzed whether these structures fell within the narrow ―minimum requirements‖ exception of the Wilderness Act. Although constructed with altruistic motives, the court found the water tanks violated the Wilderness Act because the Service failed to adequately demonstrate that these tanks were truly necessary for the conservation of the Kofa bighorn sheep population. This decision and the showing of necessity requirements it announces will impact all agency action fitting within the ―minimum requirements‖ exception

    Rock Creek Alliance v. U.S. Forest Service

    Get PDF
    A coalition of environmental advocacy groups challenged the U.S. Forest Service, U.S. Fish and Wildlife Service, and the U.S. Department of Agriculture‟s approval of a mining project near Noxon, Montana. The proposed mine would operate partially on national forest land and involve tunneling beneath the Cabinet Mountains Wilderness to extract copper and silver. The plaintiffs challenged the mine approval by advancing claims under the Endangered Species Act, National Environmental Policy Act, Clean Water Act, Organic Administration Act, and the National Forest Management Act. The court entered summary judgment for the defendants on all but two counts. Minor changes must be made to the planning and review documents on remand before the mine project is allowed to proceed

    Field Measurements of Terrestrial and Martian Dust Devils

    Surface-based measurements of terrestrial and martian dust devils/convective vortices provided from mobile and stationary platforms are discussed. Imaging of terrestrial dust devils has quantified their rotational and vertical wind speeds, translation speeds, dimensions, dust load, and frequency of occurrence. Imaging of martian dust devils has provided translation speeds and constraints on dimensions, but only limited constraints on vertical motion within a vortex. The longer mission durations on Mars afforded by long operating robotic landers and rovers have provided statistical quantification of vortex occurrence (time-of-sol, and recently seasonal) that has until recently not been a primary outcome of more temporally limited terrestrial dust devil measurement campaigns. Terrestrial measurement campaigns have included a more extensive range of measured vortex parameters (pressure, wind, morphology, etc.) than have martian opportunities, with electric field and direct measure of dust abundance not yet obtained on Mars. No martian robotic mission has yet provided contemporaneous high frequency wind and pressure measurements. Comparison of measured terrestrial and martian dust devil characteristics suggests that martian dust devils are larger and possess faster maximum rotational wind speeds, that the absolute magnitude of the pressure deficit within a terrestrial dust devil is an order of magnitude greater than a martian dust devil, and that the time-of-day variation in vortex frequency is similar. Recent terrestrial investigations have demonstrated the presence of diagnostic dust devil signals within seismic and infrasound measurements; an upcoming Mars robotic mission will obtain similar measurement types

    The Magnitude of Global Marine Species Diversity

    Background: The question of how many marine species exist is important because it provides a metric for how much we do and do not know about life in the oceans. We have compiled the first register of the marine species of the world and used this baseline to estimate how many more species, partitioned among all major eukaryotic groups, may be discovered. Results: There are ∌226,000 eukaryotic marine species described. More species were described in the past decade (∌20,000) than in any previous one. The number of authors describing new species has been increasing at a faster rate than the number of new species described in the past six decades. We report that there are ∌170,000 synonyms, that 58,000–72,000 species are collected but not yet described, and that 482,000–741,000 more species have yet to be sampled. Molecular methods may add tens of thousands of cryptic species. Thus, there may be 0.7–1.0 million marine species. Past rates of description of new species indicate there may be 0.5 ± 0.2 million marine species. On average 37% (median 31%) of species in over 100 recent field studies around the world might be new to science. Conclusions: Currently, between one-third and two-thirds of marine species may be undescribed, and previous estimates of there being well over one million marine species appear highly unlikely. More species than ever before are being described annually by an increasing number of authors. If the current trend continues, most species will be discovered this century

    Granulysin, a novel marker for extranodal NK/T cell lymphoma, nasal type

    Granulysin is a cytolytic protein expressed in cytotoxic T and natural killer (NK) cells. Abnormal serum levels of granulysin in lymphomas with NK and cytotoxic phenotype have been shown to correlate with tumour progression. In this study, we investigated the expression pattern of granulysin in routine sections of normal and reactive lymphoid tissues as well as in a large series of lymphomas. In normal tissues, granulysin labelled a small population of cells that double immunostaining revealed to belong to the pool of cytotoxic T/NK cells. Among lymphoid neoplasms, the highest expression of granulysin (71%) was found in extranodal NK/T cell lymphomas of nasal type (ENKTL). To note is that 29% of ENKTLs, which were negative for one or more of classical cytotoxic markers strongly expressed granulysin. Furthermore, expression of granulysin was observed in rare cases of T cell lymphomas with a cytotoxic phenotype (i.e. ALK-negative anaplastic large cell lymphoma (26%), enteropathy-associated T cell lymphoma (12%) and peripheral T cell lymphoma, NOS (4%)). None of the investigated non-Hodgkin B cell lymphomas, Hodgkin lymphoma and plasma cell myeloma were granulysin positive. The results suggest granulysin as a novel marker for a subset of cytotoxic NK cell derived malignancies and its usefulness is highlighted in those ENKTLs that lack expression of other cytotoxic markers but retain granulysin expression
