    Evaluation of a Pound Net Leader Designed to Reduce Sea Turtle Bycatch

    Offshore pound net leaders in the southern portion of Chesapeake Bay in Virginia waters were documented to incidentally take protected loggerhead, Caretta caretta, and Kemp’s ridley, Lepidochelys kempii, sea turtles. Because of these losses, NOAA’s National Marine Fisheries Service (NMFS) in 2004 closed the area to offshore pound net leaders annually from 6 May to 15 July and initiated a study of an experimental leader design that replaced the top two-thirds of the traditional mesh panel leader with vertical ropes (0.95 cm) spaced 61 cm apart. This experimental leader was tested on four pound net sites on the eastern shore of Chesapeake Bay in 2004 and 2005. During the 2 trial periods, 21 loggerhead and Kemp’s ridley sea turtles were found interacting with the control leader and 1 leatherback turtle, Dermochelys coriacea, was found interacting with the experimental leader. Results of a negative binomial regression analysis comparing the two leader designs found the experimental leader significantly reduced sea turtle interactions (p=0.03). Finfish were sampled from the pound nets in the study to assess finfish catch performance differences between the two leader designs. Although the conclusions from this element of the experiment are not robust, paired t-test and Wilcoxon signed rank test results determined no significant harvest weight difference between the two leaders. Kolmogorov-Smirnov tests did not reveal any substantive size selectivity differences between the two leaders

    Montana Wildlife Federation v. Bernhardt

    A federal court in Montana vacated the lease sale of several large oil and gas developments in Montana and Wyoming because BLM’s revised guidance documents, which facilitated the lease sales, failed to prioritize development outside of sage-grouse habitat, as required by BLM land use plans. BLM adopted the prioritization requirement in 2015 as part of an effort to prevent the sage-grouse from being listed under the Endangered Species Act. The court held BLM violated the Federal Land Policy and Management Act when it essentially eliminated the prioritization requirement and approved the lease sales without properly amending the land use plans

    Intergalactic Globular Clusters

    We confirm and extend our previous detection of a population of intergalactic globular clusters in Abell 1185, and report the first discovery of an intergalactic globular cluster in the nearby Virgo cluster of galaxies. The numbers, colors and luminosities of these objects can place constraints on their origin, which in turn may yield new insights to the evolution of galaxies in dense environments.Comment: 2 pages, no figures.

    The Toxicities of Some Organo-Lead Compounds for Cancer and Related Studies

    Get PDF
    In connection with the application of organo-lead compounds in cancer, some plant diseases and as anti-knock reagents, a pharmacological study has been made of the relative toxicities of a miscellany of products derived from alkyl and aryl lead compounds. Some of the salts reported at this time have varying appreciable solubilities in water
