Effect Of Soil Microtopography On Seed Bank Distribution In The Shrub-Steppe, Jere A. Boudell, Steven O. Link, Jeffrey R. Johansen

Western North American Naturalist

The relationship between soil surface cryptogamic crusts and seed banks was investigated in the shrubsteppe in the Lower Columbia Basin. Seventy-four percent of the seeds in a disturbed bunchgrass community were found in crevices bordering cryptogamic crust polygons. In a sagebrush/bunchgrass community, 89% of the seeds were found in crevices. In a disturbed bunchgrass community, Bromus tectorum seeds were found in both the seed bank and aboveground vegetation communities. Bromus tectorum seeds were located in the seed bank of a sagebrush/bunchgrass community, although it had a minor presence in the aboveground community. Seeds of Artemisia tridentata Nutt. were not found …

Trichoptera And Other Macroinvertebrates In Springs Of The Great Basin: Species Composition, Richness, And Distribution, Marilyn J. Myers, Vincent H. Resh

Western North American Naturalist

Detailed surveys of aquatic invertebrates in 28 springs along the western border of the Great Basin were made using pan traps, emergence traps, black lights, and benthic sampling devices from 1994 to 1998. Although all macroinvertebrate groups were collected, caddisflies (Insecta: Trichoptera) were sampled most intensively. Fifty-eight species of caddisflies were collected from the 28 springs, with up to 18 species from a single spring. Although several springs had very similar physicochemical characteristics, none had identical trichopteran species composition. Using Wards minimum variance clustering technique, and with all macroinvertebrates identified to the lowest possible level, we found 3 taxa assemblages. …

Three Naturally Occurring Penstemon Hybrids, Paul Wilson, Michael Valenzuela

Western North American Naturalist

Three wild Penstemon hybrids are documented herein: Penstemon clevelandii × spectabilis, P. centranthifolius × spectabilis, and P. centranthifolius × eatonii. Each putative hybrid was compared to its respective parental species using manifold floral and vegetative characters for which the parents differed. For each hybrid hypothesis, characters were counted as being intermediate or not intermediate. There were significantly more intermediate characters in all 3 cases (one-sided sign tests, P < 0.05). These Penstemon species evidently do hybridize naturally, and for nearly all characters the hybrids are consistent with the view that the parents differ largely by additive genetic effects.

Ecological Genetics And The Translocation Of Native Fishes: Emerging Experimental Approaches, Craig A. Stockwell, Paul L. Leberg

Western North American Naturalist

Conservation biologists often use translocations to augment small populations, establish "refuge" populations, or reestablish populations into historic habitat. For reasons that are poorly understood, translocations often fail. Further, translocations have both short- and long-term consequences for the evolutionary ecology of the targeted taxa. Unfortunately, most information on translocations has been derived from descriptive studies. Recent experimental approaches have provided new data to address a variety of topics associated with translocations, including inbreeding, outbreeding, the relationship between heterozygosity and fitness, and rapid evolution in populations established by translocation. We focus on genetic and ecological aspects of translocations but recognize that contributions …

Fertile Island Development Around Perennial Shrubs Across A Mojave Desert Chronosequence, John D. Bolling, Lawrence R. Walker

Western North American Naturalist

Spatial heterogeneity has been examined only recently as a factor in studies of ecosystem processes. The effect of this factor on desert organisms is exemplified in the "fertile island" a concentration of essential soil nutrients under perennial shrubs. In this study we examined fertile island patterns in undisturbed desert areas and on abandoned roadways to see at what rate and magnitude these fertile patches reappeared after disturbance. Small-scale examination of patterns of soil P, organic matter, moisture, and bulk density showed that soils beneath Larrea tridentata (DC.) Cov. shrubs on the roads lacked the tight circular gradient in these variables …

Nest-Site Characteristics Of Burrowing Owls (Athene Cunicularia) In The Snake River Birds Of Prey National Conservation Area, Idaho, And Application To Artificial Burrow Installation, James R. Belthoff, R. Andrew King

Western North American Naturalist

Burrowing Owl (Athene cunicularia) populations are declining in many portions of their range, and research and management efforts into stemming declines are underway. One tool with promise is the artificial burrow, which can supplement nesting opportunities and play a role in research, mitigation, translocation, and reintroduction studies. However, few studies directly assess important burrow and surrounding topographic features upon which owls choose sites and then construct and install artificial burrows accordingly. In this study we (1) measure physical, vegetative, and topographic characteristics of Burrowing Owl nest sites in the Snake River Birds of Prey National Conservation Area (SRBPNCA); …

Invisible Invasion: Potential Contamination Of Yellowstone Hot Springs By Human Activity, Robert F. Lindstrom, Robert F. Ramaley, Richard L. Weiss Bizzoco

Western North American Naturalist

This report establishes a baseline inventory of microorganisms in acidic hot springs of Yellowstone National Park (YNP). The analysis is based on observations carried out over the past 25 years using light microscopy, DNA staining, and electron microscopy of environmental samples. The inventory, while incomplete in that not all organisms have been cultured or examined using genetic approaches, represents a study of several solfatara (acid sulfate) geyser basins in YNP. We found that the types of microorganisms in flowing springs had changed over time. In contrast, no such changes occurred in mixing pools. We solicited opinions of prominent YNP microbiologists …

Benthos Recovery After An Episodic Sediment Release Into A Colorado Rocky Mountain River, Robert E. Zuellig, Boris C. Kondratieff, Howard A. Rhodes

Western North American Naturalist

During late September 1996, approximately 7000 m³ of clay- to gravel-sized sediment was flushed from Halligan Reservoir, Larimer County, Colorado, into the North Fork Cache la Poudre River during dam inspections. Approximately 9.6 km of this river was partially or completely affected by this episodic sediment release. Pools up to 3.2 km downstream from the dam lost 50% of their volume. Hess samples taken from October 1996 to September 1997, 100 m downstream from the dam (site 1) and 3.2 km downstream (site 2), revealed effects of sediment on recovery patterns of benthic communities. A 2-way ANOVA was used …

Status Of The Preston White River Springfish (Crenichthys Baileyi Albivallis), G. Gary Scoppettone, Peter H. Rissler

Western North American Naturalist

We determined the distribution and estimated population number of Preston White River springfish (Crenichthys baileyi albivallis) in summer 1998 and winter 1999. The total population was <5000 fish persisting in only 4 of 6 spring systems from which it had been previously captured. To improve its status, we recommend conservation measures.

Improving Seed Germination Of Salicornia Rubra (Chenopodiaceae) Under Saline Conditions Using Germination-Regulating Chemicals, M. Ajmal Khan, Bilquees Gul, Darrell J. Weber

Western North American Naturalist

Salicornia rubra Nels. (Chenopodiaceae) is a salt-tolerant annual species occurring in salt playas of the Great Basin desert in western United States. It forms pioneer communities on the most saline location of an inland salt playa at Goshen, Utah. Seeds of Salicornia rubra are capable of germinating at 1000 mM NaCl at 25–35 °C alternating temperature regime. Dormancy-regulating chemicals were evaluated for their ability to alleviate the innate and salinityenforced dormancy in seeds of Salicornia rubra. Betaine, GA3, kinetin, fusicoccin, ethephon, thiourea, proline, and nitrate had no effect in alleviating primary dormancy. Increases in NaCl concentration progressively inhibited germination …
