Nesting And Brood-Rearing Characteristics Of Chukars In West Central Idaho, Andrew J. Lindbloom, Kerry P. Reese, Peter Zager

Western North American Naturalist

We analyzed attributes from 23 nests (10 renests) and 46 brood locations of radio-marked Chukars (Alectoris chukar) in the lower Salmon River canyon of west central Idaho in 1995 and 1996. Nesting effort was 100%, apparent nest success was 45%, and estimated time from destruction or abandonment of a nest to initiation of laying a subsequent nest averaged 13 ± 5 days s_x. Average clutch size for 1st nests (14.5 ± 1.0) was greater (P = 0.017) than renests (10.4 ± 1.1). Cover types used by nesting Chukars included grass/forb (48% of nests), rock (43%), …

Effects Of Douglas-Fir Beetle (Coleoptera: Scolytidae) Infestations On Forest Overstory And Understory Conditions In Western Wyoming, Joel D. Mcmillin, Kurt K. Allen

Western North American Naturalist

Douglas-fir beetle (Dendroctonus pseudotsugae Hopk.) infestations frequently result from disturbance events that create large volumes of weakened Douglas-fir trees, Pseudotsuga menziesii (Mirb.) Franco. Previous research has focused on determining susceptibility of forest stands to Douglas-fir beetle and predicting the amount of tree mortality from Douglas-fir beetle infestations following disturbance events. Little work has been done on consequent changes in the forest overstory and understory. In the early 1990s, populations of Douglas-fir beetle increased in fire-scorched trees, subsequently infesting undamaged neighboring stands in the Rocky Mountains of western Wyoming, USA. In 1999 transect sampling and 25 pairs of previously infested …

Plant Invasions In Protected Areas At Multiple Scales: Linaria Vulgaris (Scrophulariaceae) In The West Yellowstone Area, Aníbal Pauchard, Paul B. Alaback, Eric G. Edlund

Western North American Naturalist

Invasive alien plants have long been recognized as a threat to low-elevation, disturbed environments, but the case of Linaria vulgaris Mill. in Yellowstone National Park and Gallatin National Forest shows that invasions can also spread to high-elevation natural reserves. Because invasions in protected areas are a product of complex processes occurring over a broad range of scales, we argue that a multi-scale research approach is needed to capture both patterns and potential mechanisms of the invasion process. Mapping L. vulgaris at the landscape scale, we found the species occupying a broad range of sites, apparently originating from just 2 historical …

Population Structure And Paternity In An American Black Bear (Ursus Americanus) Population Using Microsatellite Dna, Elizabeth A. Sinclair, Hal L. Black, Keith A. Crandall

Western North American Naturalist

We report genetic microsatellite data from analysis of 71 American black bears (Ursus americanus) from the East Tavaputs Plateau in eastern Utah. Heterozygosity was 52.9%, which is lower than other mainland North American populations and possibly reflects low recruitment into the study area. We used a combination of known pedigrees (mother/cubs), relatedness estimates, and paternity estimation using CERVUS to infer single and possible multiple paternity within litters, breeding by pairs over consecutive years, and the possibility of a single male successfully breeding with multiple females in a single year. Estimates of inbreeding effective population size indicate the East …

Alum And Pacl Coagulation, Winarni Winarni

Makara Journal of Technology

Alum and PACl Coagulation. Coagulation occurs by interaction of aluminum hydrolysis products with the contaminant such as colloidal particles. It is necessary to consider the different aluminum species that may present during specific conditions, since the mechanism of turbidity removal is dependent upon them. PACl consists of preformed aluminum hydrolysis products, which are stable below pH 6 and less sensitive than in situ hydrolysis product, alum. The benefits of PACl relative to alum have been investigated as a function of pH and Al dosages. Specific conditions and aluminum species that exist during the certain mechanisms of coagulation are discussed. Results …

Soil Properties Associated With Vegetation Patches In A Pinus Ponderosa–Bunchgrass Mosaic, Becky K. Kerns, Margaret M. Moore, Michael E. Timpson, Stephen C. Hart

Western North American Naturalist

Since Euro-American settlement, fire exclusion and other factors have dramatically altered interior western coniferous forests. Once open and parklike, present-day structure in many southwestern Pinus ponderosa forests consists of dense stands of young, small-diameter trees, with small patches of larger, old trees, and relict open bunchgrass areas. Our objectives were to assess differences in soil properties associated with these different vegetation patches. We examined soil morphological characteristics, pH, organic C concentration, total N concentration, C:N ratio, and phytolith concentration from profiles within 6 transects (18 soil pedons) crossing patches of dense stands of small diameter trees, patches of old-growth trees, …

Beaver Herbivory Of Willow Under Two Flow Regimes: A Comparative Study On The Green And Yampa Rivers, Stewart W. Breck, Kenneth R. Wilson, Douglas C. Andersen

Western North American Naturalist

The effect of flow regulation on plant-herbivore ecology has received very little attention, despite the fact that flow regulation can alter both plant and animal abundance and environmental factors that mediate interactions between them. To determine how regulated flows have impacted beaver (Castor Canadensis) and sandbar willow (Salix exigua) ecology, we first quantified the abundance and mapped the spatial distribution of sandbar willow on alluvial sections of the flow-regulated Green River and free-flowing Yampa River in northwestern Colorado. We then established 16 and 15 plots (1 m x 2.7 m) in patches of willow on the …

Attributes Associated With Probability Of Infestation By The Piñon Ips, Ips Confusus (Coleoptera: Scolytidae), In Piñon Pine, Pinus Edulis, José F. Negrón, Jill L. Wilson

Western North American Naturalist

We examined attributes of piñon pine (Pinus edulis) associated with the probability of infestation by piñon ips (Ips confuses) in an outbreak in the Coconino National Forest, Arizona. We used data collected from 87 plots, 59 infested and 28 uninfested, and a logistic regression approach to estimate the probability of infestation based on plot and tree-level attributes. Piñon pine stand density index was a good predictor of the likelihood of infestation by piñon ips at the plot level, and a cross-validation analysis confirmed that the model correctly classified 82% of the cases. Diameter at root collar …

Arbuscular Mycorrhizae In Thermal-Influenced Soils In Yellowstone National Park, Rebecca A. Bunn, Catherine A. Zabinski

Western North American Naturalist

Mycorrhizae are common plant-fungal symbioses occurring in most land plants. Despite their ubiquity, little is known about the distribution of arbuscular mycorrhizae (AM) in extreme environments. We surveyed for the presence of AM in thermal sites in Yellowstone National Park (YNP) where soils are characterized by extreme pHs, elevated temperatures, and toxic element concentrations. Plants at 5 sites, growing in soils with rooting-zone temperatures up to 48°C and soil pH values as low as 3.4, were mycorrhizal (colonization levels from 4% to 34%). Soils from a sparsely vegetated thermal area and an adjacent, continuously vegetated transition area differed significantly in …

Habitat Features And Predictive Habitat Modeling For The Colorado Chipmunk In Southern New Mexico, Marina Rivieccio, Bruce C. Thompson, William R. Gould, Kenneth G. Boykin

Western North American Naturalist

Two subspecies of Colorado chipmunk (state threatened and federal species of concern) occur in southern New MeXico: Tamias quadrivittatus australis in the Organ Mountains and T. q. oscuraensis in the Oscura Mountains. We developed a GIS model of potentially suitable habitat based on vegetation and elevation features, evaluated site classifications of the GIS model, and determined vegetation and terrain features associated with chipmunk occurrence. We compared GIS model classifications with actual vegetation and elevation features measured at 37 sites. At 60 sites we measured 18 habitat variables regarding slope, aspect, tree species, shrub species, and ground cover. We used logistic …

A New Record Of Heribaudiella Fluviatilis, A Freshwater Brown Alga (Phaeophyceae), From Oregon, John D. Wehr, Alissa A. Perrone

Western North American Naturalist

Members of the algal class Phaeophyceae (brown algae) are almost entirely marine species. A few genera have been described from freshwater habitats, but their distribution and ecological requirements, especially in North America, are very poorly known. The 1st specimens of a freshwater species of brown algae from Oregon, Heribaudiella fluviatilis, were discovered in 3 localities of the McKenzie River, near McKenzie Bridge and Belknap Springs (44°22′N, 122°00′-15′W). This is the 4th extant population of this species known from the United States. The alga forms distinctive, macroscopic, dark brown patches on rocks in rapidly flowing water. In the McKenzie River …
