Northern Saw-Whet Owl (Aegolius Acadicus) Migration In The Pacific Northwest, Graham G. Frye, Richard P. Gerhardt

Western North American Naturalist

Northern Saw-whet Owls (Aegolius acadicus) were captured in north central Oregon, USA, during autumn 1999 and 2000 as a pilot study on migration in the Pacific states. We captured 70 individuals, with annual capture rates comparable to those reported for larger studies in the eastern and Midwestern U.S. We investigated differential capture by time of night, time of season, and age. No results were significant due to small samples and brief duration of the study, although some results tended toward significance (P < 0.10). Here we provide a descriptive account of our observations of Northern Saw-whet Owl migration in north central Oregon, the first such study to be presented for the Pacific states.

Recurrence Of Mexican Long-Tongued Bats (Choeronycteris Mexicana) At Historical Sites In Arizona And New Mexico, Paul M. Cryan, Michael A. Bogan

Western North American Naturalist

The Mexican long-tongued bat (Choeronycteris mexicana) is a nectar-eating species that seasonally inhabits the southwestern United States. Since 1906, fewer than 1500 individuals of C. mexicana have been documented throughout the range of the species. We conducted a field survey in Arizona and New Mexico during summer 1999 to check historically occupied areas for recurrence of C. mexicana. We observed C. mexicana occupying a majority (75%, n = 18) of visited sites. Multiple individuals were observed at many sites, including young-of-year. Choeronycteris mexicana roosted in lighted areas close to entrances within mine adits, abandoned buildings, wide rock …

Plant Community Patterns In Unburned And Burned Blackbrush (Coleogne Ramosissima Torr.) Shrublands In The Mojave Desert, Matthew L. Brooks, John R. Matchett

Western North American Naturalist

The blackbrush vegetation type is dominated by Coleogyne ramossisima, which is thought to preclude the coexistence of many other plant species. Fire can remove blackbrush cover and possibly increase plant species richness and evenness. Fire also may increase the frequency and cover of alien annual grasses, thereby intensifying landscape flammability. We tested these predictions in unburned and burned (6–14 years postfire) blackbrush at 3 sites spanning the range of this vegetation type in the Mojave Desert.

Species richness in unburned blackbrush was similar to published values for vegetation types in western North America, bur richness varied significantly among the …

Roosting Behavior Of The Mexican Free-Tailed Bat (Tadarida Brasiliensis) In A Highway Overpass, Mario P. Sgro, Kenneth T. Wilkins

Western North American Naturalist

A colony of Mexican free-tailed bats (Tadarida brasiliensis) roosting in an interstate highway overpass in Belton, Bell County, Texas, was studied weekly from 28 June to 21 November 1996 (except for the week of 4 July). We examined 2 aspects of roosting behavior: site-specific fidelity to locations within the roost and gender-related segregation within the roost. Colony estimates based on guano production showed a marked decrease in the number of bats from 19 to 26 July; many of these departing bats were adult females. No female bats sampled after this interval were pregnant. Male bats outnumbered females on …

Assortative Mating In Insects: Sexual Selection Vs. Sampling Artifact, Ruth Bernstein, Stephen Bernstein

Western North American Naturalist

In this report we analyze patterns of size-assortative mating in an insect genus by (1) describing the consistency and strength of assortative mating among populations of a species and among species of a genus, and (2) determining the role of sampling artifacts in generating this nonrandom pattern of mating. Our data consist of 18 samples of soldier beetles (8 species of the genus Chauliognathus) from 17 sites within the southwestern United States. Of the 18 samples, just 6 exhibited significant correlations between elytron lengths of mating pairs. We show how these and other significant correlations are generated by 3 …

Estimates Of The Incidence Of Mistletoes In Pinyon-Juniper Woodlands Of The Coconino National Forest, Arizona, Carolyn M. Daugherty, Robert L. Mathiasen

Western North American Naturalist

The relative incidence of mistletoes found in pinyon-juniper woodlands is estimated for the Coconino National Forest, Arizona, using a roadside survey. Approximately 50% of the pinyon-juniper woodlands surveyed were infested with juniper mistletoes (Phoradendron juniperinum or P. capitellatum). In contrast, only about 12% of the areas surveyed were infested with pinyon dwarf mistletoe (Arceuthobium divaricatum). In these infested woodlands, 70% with juniper mistletoes and 44% with pinyon dwarf mistletoe were lightly infested. Most areas where pinyon dwarf mistletoe populations were observed (90%) also had juniper mistletoe (P. juniperinum) present, but many juniper mistletoe populations …

Aquatic Oligochaeta (Annelida: Lumbriculidae, Haplotaxidae, Naididae, Tubificidae) Of Utah, Douglas R. Spencer, Richard L. Denton

Western North American Naturalist

Thirty-six species of aquatic Oligochaeta (Lumbriculidae, Haplotaxidae, Naididae, Tubificidae) are now known from Utah. Aquatic habitats in 27 counties were sampled, with 32 oligochaete species identified. An additional 4 species were added from other published investigations. The majority of species are cosmopolitan and occur in other areas of North America. Nais barbata, N. alpina, and N. pardalis are reported from the western United States for the first time. Ilyodrilus frantzi was found to be a major component of the oliogochaete fauna in the Great Basin lentic environment. The North American distribution of Telmatodrilus vejdovskyi is extended significantly eastward. Tow undetermined …

Genetic Analysis Of The Rare Species Salix Arizonica (Salicaceae) And Associated Willows In Arizona And Utah, Julie T. Thompson, Renée Van Buren, Kimball T. Harper

Western North American Naturalist

Management decisions affecting the rare plant Arizona willow (Salix arizonica) will be aided by understanding genetic similarities among populations of this species. Random Amplified Polymorphic DNA (RAPD) analysis was conducted on 20 populations of S. arizonica, 12 populations of 5 congeners, and 2 samples of outgroup, Populus tremuloides. A phenogram based on DNA markers shows clear separation of populations of S. arizonica from those of co-occurring willow species, but similarity is low (~37%) between Utah and Arizona populations of S. arizonica. Evaluation of the relationship of habitat characteristics and geographic distance to genetic similarity reveals …

Distributional Information On Birds From Egg Sets Collected By Henry Rogers Durkee In 1870 In Southwestern Wyoming, Douglas B. Mcnair, James P. Dean

Western North American Naturalist

Henry Rogers Durkee collected 74 egg sets of 27 avian species in 1870 at Gilmer, Uinta County, in southwestern Wyoming. Despite the paucity of documented breeding evidence from this region during the late 19th and early 20th centuries, his material at the Smithsonian Institution was generally overlooked and has never been critically examined. Durkee's egg sets included 5 species (Sandhill Crane, Grus candensis; Northern Rough-winged Swallow, Stelgidoteryx serripennis; Grasshopper Sparrow, Ammodramus savannarum; Fox Sparrow, Passerella iliaca; Cassin's Finch, Carpodacus cassinii) whose breeding distribution was then poorly known, 25 to more than 70 years before nests …

Insect-Mediated Pollination In Slickspot Peppergrass, Lepidium Papilliferum L. (Brassicaceae), And Its Implications For Population Viability, Ian C. Robertson, Danielle Klemash

Western North American Naturalist

Field experiments on the pollination biology of slickspot peppergrass, Lepidium papilliferum L. (Brassicaceae), a rare species endemic to microsites in sagebrush-steppe habitat in southwestern Idaho, were conducted at 2 sites from May to July 2001. Site KB contained over 10,000 plants, whereas site WG contained less than 150 plants. Insect exclusion experiments revealed that seed production in L. papilliferum is dependent on insect-mediated pollination; median percent seed set dropped from 70% to 2% when insects were excluded from flowers. A total of 25 insect families from 5 orders visited L. papilliferum flowers: 24 families at KB and 11 families at …

Breeding Populations Of Swainson's Hawks, Red-Tailed Hawks, And Golden Eagles In North Central Oregon: 1975–1982 And 1999, Stewart W. Janes

Western North American Naturalist

Populations of breeding Swainson's Hawks (Buteo swainsoni), Red-tailed Hawks (B. jamaicensis), and Golden Eagles (Aquila chrysaetos) present in 1999 were compared with populations present between 1975 and 1982 at a 129-km² site in north central Oregon. Populations of Red-tailed Hawks and Golden Eagles remained unchanged, but the number of Swainson's Hawks pairs increased from 15 to 17. In 1999 Golden Eagles used nests occupied between 1975 and 1982, and 7 of 31 pairs of Red-tailed Hawks used nests occupied in earlier years. No Swainson's Hawks nested in trees occupied earlier. Few changes in …

Geobotany Of The Niobrara Chalk Barrens In Colorado: A Study Of Edaphic Endemism, Sylvia Kelso, Nathan W. Bower, Kirsten E. Heckmann, Paul M. Beardsley, Darren G. Greve

Western North American Naturalist

The chalk barrens of the Niobrara Formation in the Arkansas River valley of Colorado exhibit a high degree of plant endemism and rarity. We examined their geochemistry and structure as well as the reproductive ecology of their signature species Mirabilis rotundifolius to assess factors influencing endemism. While no single component consistently identified the barren soils, the natural locations that support Mirablilis can be identified using elemental profiles from a cluster analysis of soil extracts. Because seeds germinate and plants proliferate in transplant gardens with non-calcic soils, bedrock and soil chemistry do not appear to be determinant components of endemism. Mirabilis …

Environmental Attributes Correlating With Density Of Blackbrush (Coleogyne Ramosissima) Shrubs In The Spring Mountains Of Southern Nevada, Simon A. Lei

Western North American Naturalist

Discovery of distinct mid-elevational bands of blackbrush (Coleogyne ramosissima Torr.) shrublands on desert mountain slopes in the Mojave Desert caused an investigation of the relationships between environmental factors and Coleogyne distribution. Environmental factors were quantitatively examined to determine which were significant predictors of Coleogyne density at upper-elevational limits (ecotones) in the Spring Mountains of southern Nevada. Path analysis revealed significant, direct causal effects of air temperature, soil moisture, soil depth, and percent litter cover on the distribution of Coleogyne. Specifically, air temperature was a significant positive predictor, while soil moisture, soil depth, and percent litter cover were significant …

Dispersal Of Sagebrush-Steppe Seeds By The Western Harvester Ant (Pogonomyrmex Occidentalis), John F. Mull

Western North American Naturalist

Like many seed-harvesting ants, the western harvester ant (Pogonomyrmex occidentalis) can act as both a predator and a seed disperser. Dispersal results when seeds are dropped en route to the nest, are left in nest granaries when colonies die or are abandoned, or are removed from granaries and discarded in nest middens. This study examined the density and species identity of seeds discarded in harvester ant nest middens and compared them with those found in nearby soils. Nineteen species of seeds were recovered from middens, compared with 13 species in 5-m reference areas and 9 species in adjacent …

Difused Surface Water: Reasonable Use Has Become The Common Enemy, Wendy B. Davis

ExpressO

Diffused surface water, caused by precipitation, should be treated as a necessary asset to replenish aquifers used for drinking water, and not as waste to be disposed of by landowners. Groundwater aquifers were created, and can only be replenished, by precipitation that is allowed to seep underground. Ninety-nine percent of the drinking water for people in rural areas of America comes from groundwater aquifers. These aquifers are in danger of being contaminated or depleted, which could result in severe water shortages very soon. Legislators have failed to enact a comprehensive system to regulate the use of aquifers, relying instead on …

Pseudemys Peninsularis (Penisula Cooter). Estuarine Observation And Interaction With Giant Land Crabs, Henry T. Smith, Richard M. Engeman

United States Department of Agriculture Wildlife Services: Staff Publications

At 0710 h, 11 June 2002, a Pseudemys peninsularis was found in a Giant Land Crab (Cardisoma guanhumi) colony on an isolated isthmus of sandy spoil in a large bulkheaded estuarine canal (Intracoastal Waterway) near Woolbright Road in Boynton Beach, Florida. The spoil site was adjacent to the concrete seawall of the canal and rose < 0.5 m above the mean high tide level. The turtle was found on its back, partially covered by a fallen palm frond, and was surrounded by 20-25 easily visible crabs within 10 m, and three were within 15 cm at the initial sighting. The turtle was deeply retracted into its shell, and its right rear foot exhibited soft tissue damage apparently inflicted by crabs. It was released at ca. 0713 h into 0.25 m deep water adjacent to the island, where it remained submerged and deeply retracted into its shell when observations ended at 0720 h.

Monitoring Predators To Optimize Their Management For Marine Turtle Nest Protection, Richard M. Engeman, R. Erik Martin, Bernice Constantin, Ryan Noel, John Woolard

United States Department of Agriculture Wildlife Services: Staff Publications

The fundamental conservation focus for Hobe Sound National Wildlife Refuge (HSNWR), Florida is to provide protected nesting habitat for three threatened or endangered marine turtle species. Turtle nesting and hatching spans from early spring to fall each year. Left unchecked, nest predation by raccoons and armadillos would destroy most turtle nests. Predators are removed to protect nests, primarily with a one person-month contract using control specialists. We maximized the efficiency of predator removal by using a passive tracking index to: (1)optimize the timing and strategy for predator removal, (2)minimize labor by identifying areas where predator removal would have maximal effects, …

The Deer Boom: Discussins On Population Growth And Range Expansion Of The White-Tailed Deer, Kurt C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

The white-tailed deer (Odocoileus virginianus) is the most common and sought-after North American big game animal. More whitetails are harvested each fall than all other deer species (elk, mule deer, moose, and caribou) combined. Whitetails are popular for two main reasons, 1) their broad distribution, and 2) their abundance. The vast majority of bowhunters live in whitetail range and whitetails have experienced a population boom over the last century. Both in terms of numbers and densities, whitetails are far more abundant now than at any time during our lifetime. That is the keypoint, "during our lifetime." If the …

International Poverty Law: A Response To Economic Globalization, Timothy K. Kuhner

ExpressO

This paper is directed at poverty lawyers and, more generally, anyone with an interest in the relationship between poverty and globalization. In this paper, I argue that poverty law needs to expand its scope in order to encompass the international dimensions of poverty, and to thereby become responsive to the current nature of poverty. This need is evident, because wealth and poverty have been globalized, domestic issues have become international issues, and international issues have become domestic issues and produced domestic changes. After establishing these premises, I describe five areas of research and advocacy, each of which is located within …

Vegf164-Mediated Inflammation Is Required For Pathological, But Not Physiological, Ischemia-Induced Retinal Neovascularization, Susumu Ishida, Tomohiko Usui, Kenji Yamashiro, Yuichi Kaji, Shiro Amano, Yuichiro Ogura, Tetsuo Hida, Yoshihisa Oguchi, Jayakrishna Ambati, Joan W. Miller, Evangelos S. Gragoudas, Yin-Shan Ng, Patricia A. D'Amore, David T. Shima, Anthony P. Adamis

Ophthalmology and Visual Science Faculty Publications

Hypoxia-induced VEGF governs both physiological retinal vascular development and pathological retinal neovascularization. In the current paper, the mechanisms of physiological and pathological neovascularization are compared and contrasted. During pathological neovascularization, both the absolute and relative expression levels for VEGF₁₆₄ increased to a greater degree than during physiological neovascularization. Furthermore, extensive leukocyte adhesion was observed at the leading edge of pathological, but not physiological, neovascularization. When a VEGF₁₆₄-specific neutralizing aptamer was administered, it potently suppressed the leukocyte adhesion and pathological neovascularization, whereas it had little or no effect on physiological neovascularization. In parallel experiments, genetically altered VEGF_{164 …}
