A Comparison Of Sign Searches, Live-Trapping, And Camera-Trapping For Detection Of American Badgers (Taxidea Taxus) In The Chihuahuan Desert, Robert L. Harrison Dec 2015

A Comparison Of Sign Searches, Live-Trapping, And Camera-Trapping For Detection Of American Badgers (Taxidea Taxus) In The Chihuahuan Desert, Robert L. Harrison

Western North American Naturalist

In communities where they occur, American badgers (Taxidea taxus) play important ecological, economic, and conservation roles. Central to understanding of badger ecology and management are estimates of badger population status. However, few studies have compared methods of detecting badgers for population surveys. I compared searches for burrows and diggings, live-trapping, and the use of automatic cameras at scent lures, bait stations, and anthropogenic permanent and temporary wildlife water sources in the Chihuahuan Desert of southern New Mexico. Searches for confirmed badger burrows and diggings yielded 0.14–0.88 detections per kilometer of transect. Badgers were trapped in 1.6 ...


Using Detection Dogs And Rspf Models To Assess Habitat Suitability For Bears In Greater Yellowstone, Jon P. Beckmann, Lisette P. Waits, Aimee Hurt, Alice Whitelaw, Scott Bergen Dec 2015

Using Detection Dogs And Rspf Models To Assess Habitat Suitability For Bears In Greater Yellowstone, Jon P. Beckmann, Lisette P. Waits, Aimee Hurt, Alice Whitelaw, Scott Bergen

Western North American Naturalist

In the northern U.S. Rockies, including the Greater Yellowstone Ecosystem (GYE), connectivity is a concern because large carnivores have difficulties dispersing successfully between protected areas. One area of high conservation value because of its importance for connecting the GYE to wilderness areas of central Idaho is the Centennial Mountains and surrounding valleys (2500 km2) along the Idaho–Montana border just west of Yellowstone National Park. The current expansion of grizzly bears (Ursus arctos) and other large carnivore populations outside protected areas of Yellowstone National Park and Grand Teton National Park has placed a greater emphasis on potential linkage zones ...


Phenetic Analyses And Revised Classification Of The Ptelea Trifoliata Complex (Rutaceae), Erin Skornia, Muxi Yang, Wendy L. Applequist Dec 2015

Phenetic Analyses And Revised Classification Of The Ptelea Trifoliata Complex (Rutaceae), Erin Skornia, Muxi Yang, Wendy L. Applequist

Western North American Naturalist

The current classification of Ptelea divides the widespread and highly variable Ptelea trifoliata L. into 5 subspecies and 11 varieties, while additionally terming many specimens “intermediate.” Although there are visually observable differences among regional variants, principal component analyses of quantitative characters failed to separate subspecies or to even incompletely separate most varieties within subspecies. Some recognized subgroups are also not well distinguished by discontinuous qualitative characters. Where multiple varieties appear to be part of a single continuum of variation or are extremely similar, it is suggested that a reduction in the number of infraspecific taxa would improve the utility of ...


Facing A Changing World: Thermal Physiology Of American Pikas (Ochotona Princeps), Hans W. Otto, James A. Wilson, Erik A. Beever Dec 2015

Facing A Changing World: Thermal Physiology Of American Pikas (Ochotona Princeps), Hans W. Otto, James A. Wilson, Erik A. Beever

Western North American Naturalist

American pikas (Ochotona princeps) are of concern with respect to warming montane temperatures; however, little information exists regarding their physiological ability to adapt to warming temperatures. Previous studies have shown that pikas have high metabolism and low thermal conductance, which allow survival during cold winters. It has been hypothesized that these characteristics may be detrimental, given the recent warming trends observed in montane ecosystems. We examined resting metabolic rate, surface activity, and den and ambient temperatures (Ta) of pikas in late summer (August 2011 and 2012) at 2 locations in the Rocky Mountains. Resting metabolic rate was calculated to be ...


Production And Nutrient Content Of Two Shrub Species Related To Fire In Central Idaho, James M. Peek Dec 2015

Production And Nutrient Content Of Two Shrub Species Related To Fire In Central Idaho, James M. Peek

Western North American Naturalist

Nutrient content and weight of current year’s growth of Cercocarpus ledifolius Nuttall and Physocarpus malvaceus (Greene) Kuntze in central Idaho were obtained during early July in the years 1987–2007. The purpose of this work was to determine whether there was significant variation between years and whether mean monthly temperatures and total monthly precipitation could predict the variation. A wildfire in August 2000 causedP. malvaceus to vigorously resprout. Significant differences between years occurred for all nutrients for both species. October temperatures best predicted weight of current year’s growth in C. ledifolius, whereas prediction equations for nutrients involved ...


Maternity Roost Selection By Fringed Myotis In Colorado, Mark A. Hayes, Rick A. Adams Dec 2015

Maternity Roost Selection By Fringed Myotis In Colorado, Mark A. Hayes, Rick A. Adams

Western North American Naturalist

Fringed myotis (Myotis thysanodes) is a bat species of conservation concern in western North America that may be impacted by increased recreational activity near roost sites, changes in water resource availability caused by increased urban and agricultural water use, and anthropogenic climate change. Our purpose was to describe and model maternity roost use by fringed myotis in Colorado. We compared differences between roosts occupied by maternal fringed myotis and randomly selected potential roosting locations that were not known to be occupied by this species during the maternity period. We evaluated the strength of evidence for competing hypotheses on 2 scales ...


Black-Tailed And White-Tailed Jackrabbits In The American West: History, Ecology, Ecological Significance, And Survey Methods, Matthew T. Simes, Kathleen M. Longshore, Kenneth E. Nussear, Greg L. Beatty, David E. Brown, Todd C. Esque Dec 2015

Black-Tailed And White-Tailed Jackrabbits In The American West: History, Ecology, Ecological Significance, And Survey Methods, Matthew T. Simes, Kathleen M. Longshore, Kenneth E. Nussear, Greg L. Beatty, David E. Brown, Todd C. Esque

Western North American Naturalist

Across the western United States, Leporidae are the most important prey item in the diet of Golden Eagles (Aquila chrysaetos). Leporids inhabiting the western United States include black-tailed (Lepus californicus) and white-tailed jackrabbits (Lepus townsendii) and various species of cottontail rabbit (Sylvilagus spp.). Jackrabbits (Lepus spp.) are particularly important components of the ecological and economic landscape of western North America because their abundance influences the reproductive success and population trends of predators such as coyotes (Canis latrans), bobcats (Lynx rufus), and a number of raptor species. Here, we review literature pertaining to black-tailed and white-tailed jackrabbits comprising over 170 published ...


Life History, Burrowing Behavior, And Distribution Of Neohermes Filicornis (Megaloptera: Corydalidae), A Long-Lived Aquatic Insect In Intermittent Streams, Matthew R. Cover, Jeong Ho Seo, Vincent H. Resh Dec 2015

Life History, Burrowing Behavior, And Distribution Of Neohermes Filicornis (Megaloptera: Corydalidae), A Long-Lived Aquatic Insect In Intermittent Streams, Matthew R. Cover, Jeong Ho Seo, Vincent H. Resh

Western North American Naturalist

Several species of fishflies (Megaloptera: Corydalidae: Chauliodinae) have been reported from intermittent streams in western North America, but the life histories and distributions of these species are poorly understood. We studied the life history ofNeohermes filicornis (Banks 1903) for 2 years in Donner Creek (Contra Costa County, California), a small intermittent stream that flows for 5–7 months per year. Neohermes filicornis had a 3–4-year life span and larval growth was asynchronous. Analysis of gut contents showed that larvae were generalist predators of aquatic insect larvae including Diptera, Ephemeroptera, and Plecoptera. Final instars dug pupal chambers in the ...


First Record Of Jaguar (Panthera Onca) From The State Of Hidalgo, México, Melany Aguilar-López, Josefina Ramos-Frías, Alberto E. Rojas-Martínez, Cristian Cornejo-Latorre Dec 2015

First Record Of Jaguar (Panthera Onca) From The State Of Hidalgo, México, Melany Aguilar-López, Josefina Ramos-Frías, Alberto E. Rojas-Martínez, Cristian Cornejo-Latorre

Western North American Naturalist

We documented the first record of jaguar (Panthera onca) in the state of Hidalgo, México. With this record, the gap in the distribution of jaguar between San Luis Potosí and northwestern Puebla is reduced. In July 2013, we found 2 tracks on a trail in a pine-oak forest, and in October, we photographed a jaguar in an oak forest. Both sites are located within the Parque Nacional Los Mármoles in Sierra Gorda of Hidalgo. These records represent the first evidence of the presence of jaguar in Hidalgo, which is among the few states where all 6 species of felids that ...


A Herpetological Inventory Of Naval Air Station Fallon, Churchill County, Nevada, Jonathan P. Rose, Oliver J. Miano, Gary R. Cottle, Robert E. Lovich, Robert L. Palmer, Brian D. Todd Dec 2015

A Herpetological Inventory Of Naval Air Station Fallon, Churchill County, Nevada, Jonathan P. Rose, Oliver J. Miano, Gary R. Cottle, Robert E. Lovich, Robert L. Palmer, Brian D. Todd

Western North American Naturalist

Much of the western United States is managed by state and federal agencies for multiple uses, including recreation, grazing, extraction, and defense. Biological inventories are integral to proper management and conservation of biodiversity on these lands. We surveyed for amphibians and reptiles occurring on Naval Air Station Fallon (NAS Fallon), Nevada, USA, using a variety of methods. We documented the presence of a majority of the amphibian and reptile species native to this region of the Great Basin. We found 5 species on NAS Fallon that are listed as Species of Conservation Priority by the Nevada Department of Wildlife: the ...

Use Of External Characteristics For Rapid Identification Of Gender Of Pocket Gophers, Roger A. Baldwin, Ryan Meinerz Oct 2015

Use Of External Characteristics For Rapid Identification Of Gender Of Pocket Gophers, Roger A. Baldwin, Ryan Meinerz

Western North American Naturalist

Pocket gophers are of great importance both for their function in ecological systems and for their impact on anthropogenic environments. Managing pocket gopher populations requires a fundamental understanding of population demographics, specifically sex ratios; yet quick and reliable techniques for visually identifying gender of pocket gophers are lacking. We developed a visual identification method based on external characteristics of genitalia and mammae that allows for rapid, yet correct assessment of gender in pocket gophers. This approach was particularly accurate (>99%) for visual identifications in the field. Our approach was also accurate (>98%) for frozen specimens, although care must be taken ...


An Irrigation Canal As A Lotic Mesocosm: Examining The Relationship Between Macroinvertebrate Benthos And Drift, Peter Koetsier, Luana M. M. Mccauley Oct 2015

An Irrigation Canal As A Lotic Mesocosm: Examining The Relationship Between Macroinvertebrate Benthos And Drift, Peter Koetsier, Luana M. M. Mccauley

Western North American Naturalist

We explored the notion that small canals could be good experimental proxies of streams by documenting physiochemical parameters and macroinvertebrate community development in an aridland irrigation canal. Further, we tested the production-compensation hypothesis between benthic invertebrates and invertebrates in the water column (drift). If the hypothesis held, invertebrates in the drift would be low until the benthic carrying capacity was reached; then organisms in the drift would increase as individuals avoided overcrowded conditions in the substrate. In a small, naturalized freshwater canal, we sampled macroinvertebrates in the substrate and those in the drift once every 2 weeks over 170 days ...


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 Oct 2015

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 June and ...


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 Oct 2015

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, and both of ...


Comparative Nest-Site Habitat Of Painted Redstarts And Red-Faced Warblers In The Madrean Sky Islands Of Southeastern Arizona, Joseph L. Ganey, William M. Block, Jamie S. Sanderlin, Jose M. Iniguez Oct 2015

Comparative Nest-Site Habitat Of Painted Redstarts And Red-Faced Warblers In The Madrean Sky Islands Of Southeastern Arizona, Joseph L. Ganey, William M. Block, Jamie S. Sanderlin, Jose M. Iniguez

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 (Quercus spp.) and ...


Lichen Inventory Of White Rocks Open Space (City Of Boulder, Colorado), Erin A. Tripp Oct 2015

Lichen Inventory Of White Rocks Open Space (City Of Boulder, Colorado), Erin A. Tripp

Western North American Naturalist

A lichen inventory of White Rocks Open Space (City of Boulder, CO), a unique outcropping of exposed unstable sandstones, is presented. White Rocks is an ecologically important, ~40.5-ha (100-acre) protected area whose biological significance is in part attributable to geological and climatological history as well as degree of preservation, but also because it represents a biodiversity reservoir in a sea of agriculture and urban development. This inventory resulted in documentation of 56 species, including 1 new record to the United States, 1 new record to Colorado, 2 species new to science, and 2 additional species potentially new to science ...


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 Oct 2015

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 Oct 2015

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 ...


Food Habits Of Coyotes, Gray Foxes, And Bobcats In A Coastal Southern California Urban Landscape, Rachel N. Larson, Dana J. Morin, Izabela A. Wierzbowska, Kevin R. Crooks Oct 2015

Food Habits Of Coyotes, Gray Foxes, And Bobcats In A Coastal Southern California Urban Landscape, Rachel N. Larson, Dana J. Morin, Izabela A. Wierzbowska, Kevin R. Crooks

Western North American Naturalist

Many carnivores are sensitive to habitat fragmentation, and the capacity to shift diets may improve their ability to persist in urban areas. We collected and identified contents of a total of 119 scats from coyotes (Canis latrans), 58 scats from gray foxes (Urocyon cinereoargenteus), and 31 scats from bobcats (Lynx rufus) within habitat fragments ofvarying size in the San Diego area in coastal southern California. Coyote diet was generalist, composed of mostly mammals but also anthropogenic items, fruit and seeds, birds, and invertebrates. Dietary breadth of coyotes was similar in small urban habitat fragments and larger sites, but composition differed ...


Microhabitat Selection Of Brood-Rearing Sites By Greater Sage-Grouse In Carbon County, Wyoming, Leslie A. Schreiber, Christopher P. Hansen, Mark A. Rumble, Joshua J. Millspaugh, R. Scott Gamo, Jon W. Kehmeier, Nate Wojcik Oct 2015

Microhabitat Selection Of Brood-Rearing Sites By Greater Sage-Grouse In Carbon County, Wyoming, Leslie A. Schreiber, Christopher P. Hansen, Mark A. Rumble, Joshua J. Millspaugh, R. Scott Gamo, Jon W. Kehmeier, Nate Wojcik

Western North American Naturalist

Declines in Greater Sage-Grouse (Centrocercus urophasianus, hereafter sage-grouse) populations could be attributed to low chick survival, which may be influenced by the availability of food and cover at sites used by females rearing broods. Habitat attributes important to broods may vary regionally; thus, it is necessary to understand factors affecting regional sage-grouse brood-rearing site selection, especially when estimating the impacts of development. We monitored brood-rearing female sage-grouse equipped with solar Argos Global Positioning System Platform Transmitter Terminals from 2011 to 2013 to assess microhabitat selection by broods in Carbon County, Wyoming. We measured vegetation and arthropod characteristics at diurnal sites ...


A Note On The Observable Bark Coloration Of Quaking Aspen (Populus Tremuloides), Oren Rabinowitz, Erin A. Tripp Oct 2015

A Note On The Observable Bark Coloration Of Quaking Aspen (Populus Tremuloides), Oren Rabinowitz, Erin A. Tripp

Western North American Naturalist

The bark of quaking aspen (Populus tremuloides), a clonal hardwood that is dominant in many Rocky Mountain forests, varies from white to orange to green among both ramets and populations. The proximate causes of this color variation remain controversial. We collected 72 samples of aspen bark from 11 locations in Boulder County, Colorado, and used microscopy, dissection, and thin layer chromatography to assess the structural and biochemical basis for the color gradient. Our study shows that the cork cells closest to the cork cambium of the aspen were consistently orange and conglutinated. Outward from this layer, the cork cells transitioned ...


First Contemporary Record Of Jaguar At Morelos And The Sierra De Huautla Biosphere Reserve, Mexico, David Valenzuela-Galván, Floriely Castro-Campos, Jorge Servin, Manlio Martínez-Barona, Juan Carlos Martínez-Montes Oct 2015

Reproductive Notes On Shrews (Family Soricidae) In Louisiana, Leann Lucas, Justin D. Hoffman Oct 2015

Reproductive Notes On Shrews (Family Soricidae) In Louisiana, Leann Lucas, Justin D. Hoffman

Western North American Naturalist

Little information is known about reproduction in the 3 species of shrews in Louisiana. We examined reproductive notes from specimen records for the southern short-tailed shrew (Blarina carolinensis), least shrew (Cryptotis parva), and southeastern shrew (Sorex longirostris). Most breeding activity occurred from March to December for B. carolinensis and C. parva. Average number of embryos was 3.75 for B. carolinensis and 5.5 for C. parva. The average length of testes was 5.2 mm for B. carolinensis and 3.8 mm for C. parva. One male S. longirostris possessed a testis length of 3 mm.

Notes On The Ecology Of Reithrodontomys Microdon Based On New Records In The Eje Neovolcánico, México, Francisco X. González-Cózatl, Elizabeth Arellano Oct 2015

Notes On The Ecology Of Reithrodontomys Microdon Based On New Records In The Eje Neovolcánico, México, Francisco X. González-Cózatl, Elizabeth Arellano

Western North American Naturalist

Based on the first record in the state of Morelos and a new record for the Estado de México, we suggest that Reithrodontomys microdon preferentially uses an arboreal habitat. Specimens described here, for the most part (75%), were captured >4 m above ground on trees. Although historical records indicate that R. microdon is rare, our data may suggest otherwise. Assuming this species is preferably arboreal and that most inventories of rodents have focused on the ground, it is evident that, historically, this species has not been surveyed in its preferred habitat.

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 ...
