Biogeography Of Aquatic And Semiaquatic Heteroptera In The Grand Canyon Ecoregion, Southwestern Usa, Lawrence E. Stevens, John T. Polhemus Oct 2008

Biogeography Of Aquatic And Semiaquatic Heteroptera In The Grand Canyon Ecoregion, Southwestern Usa, Lawrence E. Stevens, John T. Polhemus

Monographs of the Western North American Naturalist

We examined the biogeography of aquatic and semiaquatic Heteroptera (ASH) in the Grand Canyon (GC) ecoregion (GCE) on and adjacent to the southern Colorado Plateau. We report 89 ASH taxa in 86 species, 37 genera, and 14 families in the GCE, including 54 ASH taxa detected within or on the rims of GC and its major tributaries, a fauna 3.8-fold greater than previously reported. We tested 2 groups of biogeographic hypotheses to account for this high level of diversity, demonstrating an underlying pattern of mixed biogeographic affinity and strong landform-climate effects. Equal numbers of ASH taxa were derived from allochthonous …

Mammals Of Great Basin National Park, Nevada: Comparative Field Surveys And Assessment Of Faunal Change, Eric A. Rickart, Shannen L. Robson, Lawrence R. Heaney

Monographs of the Western North American Naturalist

Great Basin National Park in east central Nevada encompasses most of the southern Snake Range including Wheeler Peak, which at 3980 m is the highest peak in the interior Great Basin. The original detailed surveys of the mammals of this region were made between 1929 and 1939 by field crews from the Museum of Vertebrate Zoology, University of California, Berkeley. Between 2000 and 2003, we conducted additional field surveys of mammals in the park region in conjunction with the National Park Service Inventory and Monitoring Program. Here, we provide a comprehensive report on the mammal fauna of the park and …

Monographs of the Western North American Naturalist

Information is presented dealing with the western North American species of the subfamily Donaciinae, with emphasis on data from the state of Utah. Dichotomous keys and short diagnoses are provided to enable identification of genera and species. Previously published records from Utah are summarized. For each species, the overall North American distribution is summarized, and detailed records are given for Utah. Reported host plants for each species are also listed.
