    5. R Ornithology Packages

      This forum is for posting about package specific questions that dont fit into graphing or mapping topics (ex: tidyr, RMark, R2jags). Feel to start threads on broad topics like 'dplyr' or RMark' and nest questions with in that thread.

But now a sea level rise of a fraction of an inch a year caused by climate change is pushing tides higher and higher, threatening the birds’ survival. Their population has been declining about nine percent a year since the late 1990s. They now number somewhere from 40,000 to 80,000, although overall population estimates are tentative because the birds are not always easy to find. Dr. Elphick and his colleagues recently predicted that they will reach a threshold, when the highest spring tides come too often to allow the birds time to raise their young. “After that threshold is crossed,” he says, “these birds have maybe six years before they’re extinct.”
    • Using cloud computing and data from 143 weather radar stations across the continental United States, Cornell Lab of Ornithology researchers can now estimate how many birds migrate through the U.S. and the toll that winter and these nocturnal journeys take. Their findings are published in Nature Ecology & Evolution. View the full article
    • Inspired by the negative results in the recently published largest-scale analysis of the relation between population density and positions in geographic ranges and environmental niches, Drs Jorge Soberon and Andrew Townsend Peterson of the University of Kansas, USA, teamed up with Luis Osorio-Olvera, National University of Mexico (UNAM), and identified several issues in the methodology used, able to turn the tables in the ongoing debate. Their findings are published in the innovative open access journal Rethinking Ecology. View the full article

    • Meelyn, can you please list all the batteries you've tried and the results you got. I think people will want to know what does not work as well as what does.
