Microhabitat And House Use By Dusky-Footed Woodrats (Neotoma Fuscipes) In Northwestern California: Insight From Trapping Data, Ted J. Slowik Oct 2015

Microhabitat And House Use By Dusky-Footed Woodrats (Neotoma Fuscipes) In Northwestern California: Insight From Trapping Data, Ted J. Slowik

Western North American Naturalist

Capture data differed at woodrat houses associated with selected microhabitats in a chaparral-oak woodland site in the foothills of northwestern California. Mean trapping success was significantly higher at houses located under dense tree canopy (and in low scrub cover) compared with houses in high scrub cover (and under less tree canopy), as was trapping success at houses found in non-edge versus edge habitat. Woodrats trapped at houses under dense canopy also were significantly heavier than those captured in high scrub cover; however, mean body masses at edge- and non-edge houses were similar. Broadly, our results mirror existing research but indicate …

Seasonal Variation In Reproductive Condition Of The Peco Bluntnose Shiner (Notropis Simus Pecosensis), Thomas P. Archdeacon, Sara D. Blocker, Stephen R. Davenport, Kjetil R. Henderson

Western North American Naturalist

Reproductive strategies vary among freshwater fishes. Information on reproductive characteristics is important for water managers’ efforts to protect and recover imperiled species. We describe aspects of the reproductive ecology of Pecos Bluntnose Shiner (Notropis simus pecosensis). We determined gonadosomatic index, examined ovarian condition, and counted mature ova to determine the seasonal reproductive timing and duration of Pecos Bluntnose Shiner in the Pecos River, New Mexico. Monthly changes in gonadosomatic index, ovarian stage, and number of mature ova per female suggest that Pecos Bluntnose Shiner has a reproductive season extending from April through September, with a peak occurring in …

Pine Bark Beetle And Dwarf Mistletoe Infestation In A Remnant Old-Growth Stand, Nicholas Aflitto, Tom Degomez, Richard Hofstetter, John Anhold, Joel Mcmillin, Mike Wagner, Eryn Schneider

Western North American Naturalist

We examined the incidence of bark beetle (Coleoptera: Curculionidae: Scolytinae) colonization and subsequent mortality, and the presence of dwarf mistletoe (Arceuthobium vaginatum subsp. crytopodum) within a rare remnant old-growth stand of ponderosa pine. In 2011, 96% of the old growth trees were remaining with additional dense ingrowth of ponderosa pine (Pinus ponderosa Douglas ex. Lawson) within the understory of the oldest trees. We compared the old-growth stand to abutting stands of ponderosa pine: a low-density seed-tree cut and a high-density post-1900 second growth. The old-growth stand had levels of bark beetle colonization similar to the seed-tree stand, …

Western North American Naturalist

Conservation of avian species requires understanding their nesting habitat requirements. We compared 3 aspects of habitat at nest sites (topographic characteristics of nest sites, nest placement within nest sites, and canopy stratification within nest sites) of 2 related species of ground-nesting warblers (Red-faced Warblers,Cardellina rubrifrons, n = 17 nests; Painted Redstarts, Myioborus pictus, n = 22 nests) in the Sky Island mountain ranges of southeastern Arizona. These species nested in several forest and woodland cover types that occurred along an elevational gradient. Red-faced Warblers nested primarily toward the upper end of that gradient, in pine (Pinus spp.)–oak ( …

Stream Macroinvertebrates And Habitat Below And Above Two Wilderness Fords Used By Mules, Horses, And Hikers In Yosemite National Park, Jeffrey G. Holmquist, Jutta Schmidt-Gengenbach, James W. Roche

Western North American Naturalist

Wilderness stream crossings used by mules, horses, and hikers are localized disturbances that may affect habitat immediately downstream, but the potential influence of fords on streams has received little investigation, particularly in terms of possible effects on fauna. Our overall null hypothesis was absence of below-above differences for either benthic macroinvertebrate assemblages or habitat characteristics at such fords. We further sought to determine (1) whether any such differences were present prior to annual use, suggesting longer-term effects, and (2) whether differences were present in late season, after annual use. We examined macroinvertebrates and habitat immediately below and above 2 fords …

Genetic Evidence For Recent Spread Of Springsnails (Hydrobiidae: Pyrgulopsis) Across The Wasatch Divide, Hsiu-Ping Liu, Peter Hovingh, Robert Hershler

Western North American Naturalist

The biogeographic history of aquatic organisms in relation to the Wasatch Mountains divide (which separates the eastern Great Basin and upper Colorado River basin in Utah) has been little studied aside from a large body of work on fishes. Pyrgulopsis kolobensis is a small springsnail that is distributed (in the eastern portion of its range) along the western flanks of the Wasatch Mountains, with a single population occurring just across the Wasatch divide in Strawberry Valley. Here we analyze the genetic structure of this species across the Wasatch divide (using the mtCOI gene) to discriminate between alternative hypotheses that explain …

Survival And Plant Vigor Of Sclerocactus Parviflorus (Clover And Jotter) Following Different Transplanting Techniques, Richard Ballard, Rick Ott, Tim Novotny, Anna Lincoln, Eric Rechel Oct 2015

Survival And Plant Vigor Of Sclerocactus Parviflorus (Clover And Jotter) Following Different Transplanting Techniques, Richard Ballard, Rick Ott, Tim Novotny, Anna Lincoln, Eric Rechel

Western North American Naturalist

Cacti are transplanted when their occurrence conflicts with road and pipeline construction and mitigation requires relocation, or they are transplanted for personal use. Methods used in transplanting have credence by virtue of common practice; however, there are few scientific studies comparing different methods. Our objective was to determine if different transplanting techniques, time of year of transplanting, and association with a nurse plant upon transplanting affected the long-term survival (8 years) and vigor of Sclerocactus parviflorus (Clover and Jotter). The 3 transplanting procedures were as follows: (1) cacti excavated, soil removed from roots, roots trimmed, plants placed in shaded open …

Repeated Trait Evolution Driven By Divergent Natural Selection At Early And Late Stages Of Speciation, Spencer J. Ingley

Theses and Dissertations

Speciation – the process by which new species arise – is of fundamental importance in the biological sciences. The means by which new species arise, and the relationship among living species, has been a topic that has captivated both lay and scientific observers for centuries. In recent years, the study of speciation has enjoyed increased attention, resulting in significant advances in our understanding of how species form. Although our understanding of the processes that contribute to speciation has increased dramatically in recent years, our knowledge of how reproductive barriers accumulate as speciation proceeds is still limited. Thus, studies that evaluate …

Mass Spectrometry Based Proteomics And Lipidomics Studies, Huan Kang Oct 2015

Mass Spectrometry Based Proteomics And Lipidomics Studies, Huan Kang

Theses and Dissertations

Mass spectrometry has emerged as having a vital role in various applications to biochemical fields. In this thesis, we have utilized a variety of mass spectrometry techniques for both bacteriophage proteomics and colostrum and milk lipidomics studies. Our first study was the proteome characterization of Great Salt Lake bacteriophage NS01 with SDS-PAGE GEL to separate the viral proteins and high performance liquid chromatography (HPLC) coupled with an LTQ Orbitrap to identify the proteins after in-gel digestion. In this project, we have successfully identified 11 proteins with high confidence, p-values < 0.01, including coat protein gp88 with a coverage of 91% and tail protein gp86 with a coverage of 40.96%, which facilitated the classification of NS01 as a T7-like phage. Our second study was the discovery of colostrum and milk biomarkers that can be used to predict the likelihood of development of production-related metabolic diseases (PRMDs) in dairy cows through a lipidomics approach. In this study, an electrospray ionization, time-of-flight mass spectrometer was applied to lipid profiling, quantification and significant biomolecule selection. A Q-Star quadrupole, orthogonal time-of-flight mass spectrometer and an Agilent 6530 accurate-mass quadrupole/time-of flight mass spectrometer were both used for lipid biomarker fragmentation and identification. According to linear discriminative statistical modeling, three panels of biomarkers were defined. A combination of 2 milk lipid predictors, including DG18:0/18:0 and TG 18:0/18:0/18:1, provided PRMD predictions with 75.0% sensitivity at 90.0% specificity. A combination of 3 colostrum lipid predictors, including TG16:0/18:1/18:3, DG16:0/16:0 and C40H60NO, provided PRMD prediction with 90.0% sensitivity at …

Estimating Bighorn Sheep (Ovis Canadensis) Abundance Using Noninvasive Sampling At A Mineral Lick Within A National Park Wilderness Area, Kathryn A. Schoenecker, Mary Kay Watry, Laura E. Ellison, Michael K. Schwartz, Gordon Luikart

Western North American Naturalist

Conservation of species requires accurate population estimates. We used genetic markers from feces to determine bighorn sheep abundance for a herd that was hypothesized to be declining and in need of population status monitoring. We sampled from a small but accessible portion of the population’s range where animals naturally congregate at a natural mineral lick to test whether we could accurately estimate population size by sampling from an area where animals concentrate. We used mark-recapture analysis to derive population estimates, and compared estimates from this smaller spatial sampling to estimates from sampling of the entire bighorn sheep range. We found …

Range Extension For The White-Nosed Coati (Nasua Narica) In Southeastern Guanajuato, México, María Eugenia Espinosa-Flores, Carlos A. López-González Aug 2015

Range Extension For The White-Nosed Coati (Nasua Narica) In Southeastern Guanajuato, México, María Eugenia Espinosa-Flores, Carlos A. López-González

Western North American Naturalist

We report the first photographic record of the white-nosed coati (Nasua narica) in the southeastern portion of the state of Guanajuato. Although this species is considered abundant and widely distributed in México, Guanajuato is not considered part of its current distribution. Because of the lack of records in surrounding areas, it is not possible to determine if there is an existing linkage to other populations. Thus, it is imperative to continue monitoring this species in the region to identify and assess the connectivity of other established populations and to ensure the species’ long-term conservation.
