Abstract:

Four species of Rhinichthys (R. cataractae, R. falcatus, R. osculus, and R. umatilla) are recognized in Canadian sections of the Columbia River, with sympatry occuring between all species except R. falcatus and R. osculus. Species status of the latter is supported by morphological dissimilarity between it and the morphologically similar R. falcatus and R. umatilla. Populations of R. umatilla from the Similkameen, Kettle, and Columbia (including Kootenay and Slocan) rivers have morphological and pigmentary differences, but are identifiable with R. umatilla of the lower Columbia River. Canadian R. osculus are similar to historically known populations near the Colville and Little Spokane rivers of northeastern Washington. Populations from more distant tributaries of the Columbia system are variable in morphology and habitat and require separate study to determine their relationships to Canadian populations. Rhinichthys osculus was apparently replaced by R. umatilla in the Colville River, an event that may have been correlated with historical changes of water quality or flooding by the Roosevelt Reservoir. Because R. umatilla prefers swift clear portions of large rivers, it is potentially in conflict with hydroelectric projects. Though not immediately threatened, the status of this species in Canada should be monitored in connection with future development of river systems.

Abstract:

Umatilla Dace (Rhinichthys umatilla, Cyprinidae) are endemic to the Columbia River Basin. In Canada, this species is assessed as “threatened”. Little is known about its life history, especially with respect to spawning in the wild. A total of 688 specimens were captured, including 39 mature males and females displaying spawning colouration and tubercles, during minnow trapping and electrofishing surveys conducted on the Slocan River in southern British Columbia, Canada. Fertilized eggs were not observed, but eggs and milt were expressed from ripe individuals. Spawning was estimated to occur from mid-July to mid-September. Aquatic macrophytes and flooded terrestrial vegetation were important habitat features for mature Umatilla Dace leading up to the spawning period on the Slocan River. To our knowledge this is the first time that Umatilla Dace have been captured in spawning condition and observed with spawning colouration and tubercles in the wild in Canada. Results of this study will aid the development of recovery plans and management for this species in British Columbia.

Abstract:

`Umatilla Russet' and `Russet Legend', two newly released potato (Solanum tuberosum L.) cultivars were compared with four established cultivars (`Russet Burbank', `Shepody', `Frontier Russet', and `Ranger Russet'). Potatoes were grown under four, season-long, sprinkler irrigation treatments in three successive years (1992-94) on silt loam soil in eastern Oregon. At each irrigation, the full irrigation treatment received up to the accumulated evapotranspiration (ETc) since the last irrigation. Three deficit irrigation treatments had progressively less water. The new cultivars `Umatilla Russet' and `Russet Legend' performed as well as or better than the other cultivars in the full irrigation treatment, with `Umatilla Russet' showing a higher yield potential at the higher water application rates than `Russet Legend'. All cultivars produced more U.S. No. 1 tubers than `Russet Burbank', except in 1993, an unusually cool and wet year. `Russet Legend' was the only cultivar showing a tolerance to deficit irrigation. In two out of the three years, `Russet Legend' was as productive of U.S. No. 1 yield over most of the range of applied water as `Shepody', `Frontier Russet', and `Ranger Russet' were at the higher end of the applied water range. Chemical names used: 0,0-diethyl S-[(ethylthio) methyl] phosphorodithioate (phorate); N-(1-ethylpropyl)-3,4-dimethyl-2,6-dinitrobenzenamine (pendimethalin); and 2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1methyl-ethyl) acetamide (metolachlor).

Abstract:

We discovered unique Douglas-fir open woodlands in the Umatilla National Forest using historical surveys. Historical ponderosa pine forests of the western United States are transitioning to denser forests comprised of a greater proportion of fire-sensitive species, including true firs. We used historical (1879 to 1887) surveys to quantify the composition and structure of the Umatilla National Forest in eastern Oregon and Washington and provided contemporary forest information for comparison. We also modeled fir and pine distributions using environmental predictors and the random forests and extreme gradient boosting classifiers. Historically, ponderosa pine and Douglas-fir comprised about 80% of all trees, with western larch relatively abundant at 10% of all trees. Currently, ponderosa pine and Douglas-fir are about 40% of all trees, while grand fir and lodgepole pine increased from rare species to about 40% of all trees. Historical density was about 165 trees/ha (trees > 12.7 cm in diameter). The wetter north unit of steep slopes and predominantly Douglas-fir was about 120 trees/ha, or open woodlands, whereas the drier, flatter south units of predominantly ponderosa pine were about 210 trees/ha, and densities of 160 and 190 trees/ha occurred on flat and gentle slopes, respectively, with predominantly ponderosa pine. Currently, Umatilla National Forest averages about 390 trees/ha; the north unit of grand fir and Douglas-fir tripled in density to 365 trees/ha, whereas the south units of ponderosa and lodgepole pines doubled in density to 410 trees/ha. Douglas-fir woodlands are an unusual combination of a relatively fire-sensitive tree species with an open structure, which may result from surface fires that remove tree regeneration, resulting in one layer of trees over an understory of herbaceous and shrubby vegetation. We interpreted that a spatially and temporally variable fire return interval favored Douglas-fir, but fires were frequent enough to allow herbaceous vegetation and shrubs to out-compete trees, maintaining the balance between trees and other vegetation in woodlands. Fire exclusion has resulted in forest-type transition and also an information deficit about circumstances under which relatively fire-sensitive Douglas-fir instead of fire-tolerant ponderosa pine would establish at low densities over large extents.

Abstract:

Alternaria spp. were collected from potato foliage showing symptoms of early blight and brown spot in the Columbia Basin, WA and Bonners Ferry and Rupert, ID between 2009 and 2011. The aggressiveness of three Alternaria spp. on potato was quantified on nonwounded and wounded detached leaves of ‘Russet Norkotah’ potato; wounded detached leaves of ‘Alturas’, ‘Ranger Russet’, ‘Russet Burbank’, and ‘Umatilla Russet’; and whole plants of Russet Norkotah. Mean infection frequencies (MIF) and area under the lesion expansion curve (AULEC) were significantly greater for Alternaria solani (P = 0.0072 and 0.0002, respectively) than for A. arborescens or A. arbusti on nonwounded leaves. Wounding of tissue significantly increased MIF and AULEC for A. arbusti (P = 0.008 and 0.0047, respectively) and AULEC for A. arborescens (P = 0.01) relative to nonwounded tissue. AULEC did not differ significantly among the three Alternaria spp. when inoculated onto wounded foliage of whole plants (P = 0.34); the AULEC of whole plants was positively and significantly correlated with AULEC on detached leaves (P = 0.03). Umatilla Russet was the most susceptible and Russet Burbank was the least susceptible based on MIF and AULEC for all three pathogen species. Results indicate that A. solani was the more aggressive pathogen of potato in the Columbia Basin, because both A. arborescens and A. arbusti require wounds and A. arbusti lesions do not expand significantly in comparison with A. solani or A. arborescens following inoculation.

Abstract:

Abstract Anadromous salmonids can be vulnerable to entrainment at diversion intake structures on streams, effectively trapping fish in irrigation canals and removing them from a population. Currently little is known about how the differences in timing and direction of movement among adult salmonids contribute to their risk of entrainment and how successful they are at escaping irrigation canals. Potential routes of escape include passing against water currents and through the headgate of an irrigation canal intake or by navigating through screen and bypass infrastructure primarily designed to return juvenile fish to a stream. In this study, passive integrated transponders (PIT tags) were used to track the movement of adult Chinook Salmon Oncorhynchus tshawytscha (n = 573), Coho Salmon Oncorhynchus kisutch (n = 39), and anadromous Rainbow Trout Oncorhynchus mykiss (steelhead, n = 853) as they entered areas of the Umatilla River basin (Oregon) with irrigation canals and as they attempted to escape irrigation canals after entrainment. Although adult steelhead and spring Chinook Salmon often encountered diversions at similar times, the vast majority of entrained adults were steelhead (94%). Between 2% and 8% of adult steelhead observed entering the area were entrained. The entrainment of steelhead was strongly associated with downstream movements and Umatilla River discharge below 40 m3/s. Many downstream-moving steelhead were postspawning fish (kelts). As a result, vulnerability of anadromous adults to entrainment differed by species due to the direction of their movements and how these movements coincide with canal operations and river flows. It is unlikely that the screened irrigation canals acted as an ecological sink; the majority of adult salmonids approached the screen and bypass infrastructure (≥88%) and later river detection confirmed that many had used that infrastructure to return to the river (≥47%). However, half of steelhead appeared to experience bypass delays at fish screens. Adult steelhead that approached the canal headgate after becoming trapped in the canal did not successfully return to the Umatilla River using this route. Unscreened irrigation canals elsewhere may disproportionally trap downstream-moving steelhead, like postspawning kelts, due to their propensity for entrainment and their difficulties escaping through the water intakes of irrigation canals. In streams with anadromous salmonids, fish screen and bypass infrastructure primarily designed to eliminate the permanent entrainment of juvenile fish can also prevent the removal of adult fish that may reproductively contribute to the population.

Abstract:

The Columbia Basin of Oregon consists of six counties (Gilliam, Hood River, Morrow, Sherman, Wasco, and Umatilla) and is the major wheat-producing region in the state. In 2005, these counties produced 300,277 ha of mostly fall-planted wheat. While primarily a dryland production area, wheat (approximately 8,094 ha) is also grown as a rotational crop under irrigation. Stunted and chlorotic winter wheat plants with leaves exhibiting a mosaic pattern consistent with that caused by Soilborne wheat mosaic virus (SBWMV) were observed in March 2005. These plants originated from four center-pivot irrigated fields in Umatilla County with each field approximately 50.6 ha. One-half of one field was planted with cv. Western Breeders 470 (WB470) and the other half with cv. Tubbs, while the three other fields were planted to Tubbs. In the split-planted field, symptoms were widespread in the WB470 half but only observed in low-lying areas planted with Tubbs. ELISA with a monoclonal antibody (Agdia Inc., Elkhart, IN) confirmed the presence of SBWMV, which is transmitted by the soilborne organism Polymyxa graminis. Electron microscopy confirmed rigid, rod-shaped particles that were 19 nm wide and of two size classes, 138 to 222 and 416 to 471 nm long. Presence of SBWMV was further verified by reverse transcription (RT)-PCR using SBWMV RNA-2 specific primers (sense 5′-AAAGAGTCTIGCGTRTARCAYTC-3′ and antisense 5′-AACGGTGTTAGTAARYTRGGKGA-3′), which amplified the predicted 338-bp product from the coat protein gene (1). Additional positive samples were found in 2006 from fall-planted wheat cvs. WB 528 and MJ9 from two additional 50.6-ha fields in Umatilla County. In 2005, yield of WB470 in the split-planted field was reduced by approximately 15% compared with yields obtained in similar fields planted with WB470 not exhibiting symptoms. SBWMV has been reported previously in Oregon (2) but nearly 322 km to the west in an area that is not the major wheat-producing region in Oregon. Because of the apparent reduced susceptibility of Tubbs, which is an older cultivar, as compared with WB470, WB528, and MJ9, which are three new high-yielding cultivars, additional research is needed to identify the reaction to SBWMV of cultivars adapted for production in the Pacific Northwest, particularly if this disease becomes widely distributed in both irrigated and dryland production areas.

Abstract:

Powdery scab of potato, caused by Spongospora subterranea f. sp. subterranea, has increased in incidence since 1981 to become a major concern for potato production in the Columbia Basin of south-central Washington and north-central Oregon. Disease symptoms consist of pustules on the tuber surface and wart-like galls on roots, stolons, and tubers. In the current study, the effect of powdery scab root galls on potato yield was quantified by comparing yields of cultivars susceptible and resistant to root galling grown on soil naturally infested and noninfested with the powdery scab pathogen. Potato tuber yields for the three yield components of yield per plant, number of tubers, and weight of tubers were not negatively affected by powdery scab galls on roots of Umatilla Russet and Shepody, as indicated by yield ratios ≥1.0 in 3 of 4 years, and also by regression analyses in all 3 years. Regression lines with a nonsignificant slope or slopes that significantly increased with gall index also indicated that root galls did not negatively affect yield. Mean tuber weight increased as gall index increased for Umatilla Russet in 2 of 3 years. Consequently, control tactics directed solely at reducing powdery scab galls on roots are not justified economically under conditions encountered in the Columbia Basin of Washington and Oregon states. Effort has been made to develop resistant cultivars and search for soil applied chemicals to reduce root galls.

Abstract:

Abstract Although the importance of wildfire to fire-adapted ecosystems is widely recognized, wildfire management has historically placed less emphasis on the beneficial effects of wildfire. We estimate the avoided fuel treatment cost for 10 ponderosa pine (Pinus ponderosa) stands on the Umatilla National Forest in the Pacific Northwest. Results show that fires in stands that show the greatest divergence from the archetypical ponderosa pine stand structure (large trees in an open, parklike stand) tend to have higher avoided costs. This is a reflection of the higher cost of fuel treatments in these stands: treatments designed to restore a stand to a desired condition are normally more expensive than treatments to maintain a stand in a desired condition.

Abstract:

In August of 2011, potato (Solanum tuberosum) tubers grown in the lower Columbia Basin of southern Washington State and northern Oregon were observed with internal discolorations suggestive of zebra chip disease (ZC). Symptoms included brown spots, streaks, and stripes in and near the vascular tissue, typical of ZC (1). Symptoms were observed in cvs. Alturas, Russet Norkotah, Pike, Ranger Russet, Umatilla Russet, and Russet Burbank. Foliar symptoms on plants that produced symptomatic tubers included purple discoloration in upper leaves, leaf rolling, axial bud elongation, chlorosis, leaf scorch, and wilt. Tissue was taken from two symptomatic tubers each of cvs. Alturas and Russet Norkotah, three tubers of cv. Umatilla Russet, and one tuber of cv. Pike. These tubers were tested by PCR for “Candidatus Liberibacter solanacearum”, an unculturable alphaproteobacterium associated with ZC (1,4). Primers specific for the 16S rDNA were CLipoF (4) and OI2c (3), and primers OMB 1482f and 2086r were specific for the outer membrane protein (2). All of these samples, except one Umatilla tuber, were positive for the bacterium. The 16S rDNA and OMB amplicons from one symptomatic tuber each of Alturas (from Washington) and Pike (from Oregon) were cloned and three clones of each were sequenced. BLAST analysis of the consensus sequences confirmed “Ca. L. solanacearum”. The 16S sequences (1,071 bp) from the two tubers were identical and showed 99 to 100% identity to a number of 16S rDNA sequences of “Ca. L. solanaceaum” in GenBank (e.g., Accession Nos. HM246509 and FJ957897). The 16S rDNA sequences were deposited in GenBank as Accession Nos. JN848751 and JN848753. Consensus sequences of the two OMB clones (605 bp; deposited in GenBank as Accession Nos. JN848752 and JN848754) were identical and showed 97% identity to the two “Ca. L. solanacearum” OMB sequences in GenBank (Accession Nos. CP002371 and FJ914617). Potato psyllids (Bactericera cockerelli Sulc), the vector of “Ca. L. solanacearum”, were present in ZC-affected fields in Oregon and Washington and the bacterium was confirmed by PCR in 5 to 10% of 128 adult psyllids collected from two fields. On the basis of foliar and tuber symptoms, specific PCR amplification with two primer pairs, sequence analyses, and the presence of Liberibacter-infected potato psyllids, ZC and “Ca. L. solanacearum” are present in potatoes in Oregon and Washington State. Washington and Oregon together grow ~80,000 ha of potatoes. ZC has caused significant economic damage to potatoes in Texas, Mexico, Central America, and New Zealand (1). Therefore, ZC may pose a risk to agriculture in Oregon, Washington, and neighboring states. However, the potential for development of widespread and serious disease will depend upon the arrival time and number of infective potato psyllids entering the region. References: (1) J. M.

Abstract:

Cultural resource management (CRM) is nothing new in Indian Country. American Indians have always managed their natural and cultural resources with respect by remembering where we originated from—Mother Earth. Remembering those who came before us Native peoples inherit the responsibility to protect our traditional tribal way of life for generations to come. The Mid-Columbia River tribes known as the Umatilla Cayuse, and Walla Walla have been forced into many battles over land and resources since the passing of Lewis and Clark in 1805. Many of these battles have been simply to gain recognition as indigenous people who have the aboriginal right to manage those resources connecting us to our ancestral cultural heritage. This is a difficult task when simultaneously observing the desecration, or outright destruction, of aboriginal resources during the recent historic past.

Abstract:

Resistance to Phytophthora infestans in leaves, stems, flowers, and tubers of eight cultivars grown commercially in the Columbia Basin and 29 advanced clones from the Tri-State Potato Variety Development Program was quantified. Foliage of all eight cultivars was susceptible in field and greenhouse tests. Six advanced clones had high levels of resistance in stems and leaves in the field at Mount Vernon, WA, but only two of these six clones had high levels of resistance in leaves and stems in greenhouse tests. Flowers of most plants with high to moderate levels of foliar resistance were susceptible to infection in both the field and greenhouse. Tubers of Umatilla Russet, Russet Legend, Gem Russet, and nine advanced clones, including A90586-11, had high levels of resistance in most laboratory tests. Level of foliar resistance against US-8 and US-11 clonal lineages of P. infestans was variable among clones, but tuber resistance by pathogen clonal lineage varied little among clones. Clones with high resistance expressed quantitative differences compared with susceptible cultivars and likely possess a high level of partial resistance.

Abstract:

Topographic and climatic influences have controlled thick loess accumulation at the southern margin of the Palouse loess in northern Oregon. Juniper and Cold Springs Canyons, located on the upwind flank of the Horse Heaven Hills, are oriented perpendicular to prevailing southwesterly winds. These canyons are topographic traps that separate eolian sand on the upwind side from thick accumulations (nearly 8 m) of latest Pleistocene to Holocene L1 loess on the downwind side. Silt- and sand-rich glacial outburst flood sediment in the Umatilla Basin is the source of eolian sand and loess for the region. Sediment from this basin also contributes to loess accumulations across much of the Columbia Plateau to the northeast. Downwind of Cold Springs Canyon, Mt. St. Helens set S and Glacier Peak tephras bracket 4 m of loess, demonstrating that approximately 2500 g m−2 yr−1 of loess accumulated between about 15,400–13,100 cal yr B.P. Mass accumulation rates decreased to approximately 250 g m−2 yr−1 from 13,100 cal yr B.P. to the present. Tephrochronology suggests that the bulk of near-source Palouse loess accumulated in one punctuated interval in the latest Pleistocene characterized by a dry and windy climate.

Abstract:

Colour is an important character in the processing of potatoes for French fries. French fry colour is closely associated with sugar content in the tuber. This study examines the stability of yield, sugar content and French fry colour for eight potato cultivars and advanced selections in four environments. Stability was determined using three approaches based on the Eberhart-Russell, Tai and GGE Biplot analyses. The GGE Biplot analysis provided a better characterization of stability than the other two analyses. The most stable and best performing genotypes for both French fry colour and total sugars were Russet Burbank and Umatilla Russet. Cal White had high yield and yield stability but had average stability for poor (dark) French fry colour. The GGE biplot analysis was able to identify mega-environments and those environments which optimized differentiation between genotypes. Both factors are important for the optimization of resources for testing new genotypes. Stability for quality factors in potato can be as important or more important than yield for some processing uses. In this study, genotypes with stability for sugar content and French fry colour were identified and these may be used as parents in breeding for stability. Key words: Potato, yield stability, quality, French fry

Abstract:

Potato (Solanum tuberosum) selections (clones and commercial cultivars) were examined for resistance to root galling, caused by the powdery scab pathogen Spongospora subterranea f. sp. subterranea in seven field trials conducted between 2003 and 2007 in the states of Washington and Idaho. Four industry reference cultivars—Shepody, Russet Burbank, Russet Ranger, and Umatilla Russet—were used as susceptible standards. Every year, selections less susceptible than the standards were considered resistant and progressed to the next season. Selections that did not demonstrate resistance in at least two consecutive trials were discarded. Eight potato selections were more resistant to root galling than the susceptible standards in two or more trials: PA98NM38-1 was more resistant than the susceptible standards in 5 of 5 trials, PO94A009-10 in 4 of 5 trials, PA95B2-4 and PA98N5-2 in 3 of 5 trials, POR00HG5-1 in 2 of 5 trials, PO94A009-7 in 3 of 4 trials, PO94A012-2 in 2 of 3 trials, and Summit Russet in 2 of 2 trials. POR00HG5-1 has Solanum hougasii in its ancestry, while the other selections have the Mexican wild species Solanum bulbocastanum and the commercial cultivar Summit Russet appearing in their ancestry. Summit Russet is the most plausible source of resistance.

Abstract:

Potato (Solanum tuberosum) germplasm was tested for resistance to stem colonization by the black dot pathogen Colletotrichum coccodes. Forty-six potato selections were tested in three field trials from 2006 to 2008. Resistance was determined by comparing disease severity on aboveground stems to the mean disease severity of the industry standards Russet Burbank, Ranger Russet, and Umatilla Russet. The potato selections were also tested for genotype*environment interaction to determine their genetic stability. Heritability of resistance was calculated to be 0.13 with confidence intervals between 0.00 and 0.68. The selections A0012-5, PA95B2-4, PA98NM38-1, and PO94A009-7 had less black dot than the standards in all years, and also demonstrated genetic stability. These selections also possess resistance to the root galling stage of the powdery scab pathogen Spongospora subterranea f. sp. subterranea. PA95B2-4, PA98NM38-1, and PO94009-7 were derived from an introgression program to incorporate resistance to the Columbia root-knot nematode Meloidogyne chitwoodi from the Mexican wild species Solanum bulbocastanum, and also have the commercial cultivar Summit Russet in their ancestry. These selections are promising steps toward sustainable management of black dot and powdery scab and will be further tested and used for breeding purposes.

Abstract:

A stem inoculation assay was developed to assess transmission of Phytophthora infestans from the base of belowground potato stems to emerged aboveground shoots. Sporangia of P. infestans subsequently developed on aboveground stems after belowground stems were inoculated with isolates BF05 (US 8 genotype), WA10.1 (US 24), and 110B (US 11) by (i) placing a filter paper square saturated with a spore suspension onto nonwounded belowground stem tissue, (ii) placing a filter paper square saturated with a spore suspension onto wounded belowground stem tissue, and (iii) dipping the base of the cut belowground stem into a spore suspension. Plant stems were then incubated in a humidity chamber at 10 to 21.5°C for 7 to 28 days. Incidence of aboveground stems with sporulation was significantly less when stems were inoculated with isolate 110B than with isolates BF05 and WA10.1 but length of latent period did not differ among the three isolates. Incidence of aboveground stems with sporangia was significantly (P < 0.05) greater for ‘Russet Norkotah’ than for ‘Umatilla Russet’ when inoculated near the point of seed piece attachment. Incidence of aboveground stems with sporulation did not differ among incubation temperatures of 10, 15, and 21.5°C. Latent period significantly increased as temperature decreased. Age of stem did not appear to affect incidence of transmission. Incidence of transmission of P. infestans to aboveground stems from the base of belowground stems was significantly lowered when aboveground stems were treated with selected fungicides 1 h before inoculation.

Abstract:

A study was undertaken in 2008 and 2009 to examine potato (Solanum tuberosum) cultivar susceptibility, the potential of other host species to act as sources of inoculum for potato infections, and other aspects of potato–Phytophthora nicotianae interactions. Twelve isolates of P. nicotianae collected from five leaf, one petiole, and six tuber infections of potato from five states, as well as isolates from a variety of other host species, were evaluated for ability to cause tuber rot of potato via inoculation studies. Additionally, the susceptibility of 27 potato cultivars commonly grown in the United States to tuber infection by P. nicotianae was determined. Eighty-three percent of the isolates recovered from potato were highly aggressive, infecting tubers at nearly four times greater incidences than isolates originating from nonpotato hosts. With the exception of two tobacco isolates, zoospores of all isolates recovered from nonpotato hosts were able to infect potato tubers. Russet cultivars were significantly less susceptible to P. nicotianae than red and white cultivars in 2008, and red cultivars in 2009. Umatilla Russet was the most resistant cultivar in both years, whereas Red Norland and Dakota Rose were the most susceptible in both years. Results of a survey for P. nicotianae conducted in four states from 2008 through 2010 confirmed previous observations of naturally occurring infections of potato in Missouri, Nebraska, and Texas, as well as infections of potato in Michigan (documented for the first time). All isolates recovered in the survey were sensitive to mefenoxam (EC50 < 1.0 μg/ml).

Abstract:

The most recent opinion in the so-called Kennewick Man or Ancient One (as many American Indians choose to call the skeleton) case by the United States Court of Appeals for the Ninth Circuit unfortunately resurrects some very old and contentious issues in America. Indians mostly view the opinion as one more echo of the same old story of Native American property issues raised in the courts, but they also understand that some implications may be broader. The most direct impact of the opinion is that the Umatilla people will not be allowed to return the Ancient One to the earth, but others could be portents of a larger resurgence of anti-Indian sentiment and scientific colonialism in America. Specifically, though not directly stated as such, the court's opinion supports a notion that archaeological materials are a public heritage, no matter their culture of origin. In addition, by affirming the plaintiffs' position, the court essentially declared archaeologists and associated scientists to be the primary stewards of that heritage, much to the chagrin of many American Indian people. Along the way, the court reinforced the idea that scientifically generated evidence has greater validity than oral tradition in court, outright denying oral tradition's validity and undercutting a major intention of the Native American Graves Protection and Repatriation Act (NAGPRA). Worse still, the court reflects—and by its decision supports—an idea that there may be a “white” or European history for the Americas that predates the arrival of Indians. The most damaging and long-term impact is that the decision reinforces fundamentally erroneous definitions and stereotypes about Indians as tribes, which has plagued Indian-white relations for generations.

Abstract:

North American isolates of Colletotrichum coccodes, representing six vegetative compatibility groups (NA-VCG), were used to study morphological and pathogenic variability. The objective was to determine if variability in conidial and microsclerotial size was related to pathogenicity. Significant differences were detected in length, width, and length/width ratios of conidia as well as in the length and width of microsclerotia among the NA-VCGs. The longest and widest conidia were produced by isolates belonging to NA-VCG1 and the largest microsclerotia were produced by isolates of NA-VCG2. Conidial and microsclerotial lengths and widths also were affected significantly by type of growth medium. There was no relationship between the size of conidia and the size of microsclerotia among the NA-VCGs studied. Conidial and microsclerotial size may affect inoculum potential and survival as isolates of NA-VCG2 have been demonstrated to occur more frequently than other NA-VCGs. Aggressiveness of 17 isolates of C. coccodes representing six NA-VCG's was studied on three potato cultivars using foliar and root inoculation methods. C. coccodes infection reduced tuber weight in all cultivars with both inoculation methods although tuber weight reductions were significantly higher following root inoculations than foliar inoculations. Pathogenic aggressiveness varied among NA-VCGs. Isolates belonging to NA-VCG2 and 3 were the least aggressive on potato foliage and isolates of NA-VCG1, 2, 3, 4, and 5 produced higher microsclerotial density on all three cultivars compared with isolates of NA-VCG6. Across inoculation methods, isolates of C. coccodes belonging to NA-VCG2 and 6 were the most aggressive based on reductions in tuber weight. Umatilla Russet was the most susceptible cultivar to C. coccodes compared to other cultivars regardless of inoculation method. These results demonstrate variability in morphology and pathogenic aggressiveness among the NA-VCGs of C. coccodes but these traits are not related.

Abstract. New cost-effective strategies are needed to reclaim soils disturbed from mining activity on National Forests. In addition, disposal of waste wood from local timber harvest operations or biosolids from waste water treatment plants can be expensive. Therefore, using organic byproducts for soil reclamation activities on National Forests may provide an opportunity to increase soil cover and productivity, and decrease restoration costs. To test the effectiveness of these amendments for reclamation, a field study was established using organic amendments applied to gold dredgings capped with 10 cm of loam and with little regenerating vegetation within the Umatilla National Forest in northeastern Oregon. Study plots had biochar (11 Mg/ha), biosolids (17 Mg/ha), or wood chips (22 Mg/ha) applied singly or in combination. Each plot was divided in half. One half of the plot was seeded with native grasses and forb and the other half was planted with a combination of California brome ( Hook & Am.) and Jepson’s blue wildrye ( Buckl.). After two growing seasons, there were no significant differences in plant cover between the planted or seeded plots. Biosolids, biosolid + biochar + wood chips, and biosolid + wood chips had greater grass and forb planted cover after two years; seeded plots on the biosolid + biochar + wood chips and biosolid + wood chip treatments had the greatest grass and forb cover. Soil properties were significantly altered by individual treatments; combination treatments improved nutrient availability and soil moisture, resulting in up to twice as much plant cover than in the control plots. Forest managers can produce biochar and wood chips from the abundant forest waste generated during harvest operations, and class “A” biosolids are available in Oregon from local municipalities. Using these three amendments in combination to restore disturbed mine soils can provide an affordable and effective strategy.

Abstract:

Phosphorous acid for control of tuber rots caused by Phytophthora infestans, P. erythroseptica, and Pythium ultimum was applied to foliage of potato cultivars at various application timings and rates under growing conditions in the Pacific Northwest at Othello and Mount Vernon, WA, and Bonners Ferry and Aberdeen, ID in 2001 to 2003. Efficacy was assessed by artificially inoculating harvested tubers. Mean incidence and severity of late blight tuber rot in tubers inoculated with US-8 and US-11 isolates of Phytophthora infestans usually were significantly less when the foliage from which the tubers were obtained was treated with phosphorous acid than when it was not treated at all locations. With two applications of phosphorous acid, late blight tuber rot in the tuber-resistant cv. Umatilla Russet was significantly less than for Ranger Russet. For phosphorous acid at a rate of 9.37 kg a.i./ha, late blight tuber rot control achieved with two applications at 2-week intervals was not consistently improved across locations by making an additional application 2 weeks later. In 2003, incidence and severity of late blight tuber rot did not differ significantly between the rates of 7.49 and 9.37 kg a.i./ha at both Othello and Mount Vernon. Late blight tuber rot incidence and severity were significantly less at a rate of 7.49 kg a.i./ha when the application schedule began at initial tuber bulking rather than when the first application was made 4 weeks after initial tuber bulking at Othello, but not Mount Vernon. Incidence of pink rot was significantly less in inoculated tubers from plots treated with three applications of phosphorous acid than in tubers from nontreated control plots at Mount Vernon in 2002 and 2003, Bonners Ferry in 2002, and Aberdeen in 2003. Pink rot severity was reduced significantly by both two and three phosphorous acid applications at Mount Vernon in 2002. Pink rot incidence, but not severity, was reduced significantly at all timings when either 7.49 or 9.37 kg a.i./ha was applied at Mount Vernon in 2003. Control of Pythium spp. by phosphorous acid was not evident in this study. Total tuber yield at harvest did not differ significantly among the phosphorous acid treatments and the nontreated control at Othello and Mount Vernon in 2001 and 2002.

Abstract:

In July 2007, potato tubers cv. Russet Burbank (RB) with necrotic arcs and spots were detected in three fields in Buffalo County, Wisconsin and one field in Benson County, Minnesota. Umatilla Russet (UR) potatoes harvested from the west half of a field in Swift County, MN had similar, but visually distinct necrotic lesions. Portions of one field in Minnesota were abandoned, and the stored potato crop from two fields in Wisconsin was rejected by processors, representing a total crop loss due to tuber necrosis. Tuber symptoms displayed in both cultivars resembled those described for corky ringspot caused by Tobacco rattle virus (TRV) (4). Total RNA was isolated from necrotic tuber tissue crushed in liquid nitrogen and extracted using the Total RNA Isolation Kit (Promega Corp., Madison, WI). These extracts were tested for the presence of TRV by reverse transcription (RT)-PCR using primers complementary to nucleotides 6555 to 6575 and identical to nucleotides 6113 to 6132 within the 3′ terminal open reading frame of TRV RNA-1 (3). The expected 463-bp fragments were amplified from RB tubers. Nucleotide sequences from a Wisconsin and Minnesota isolate (GenBank Accession Nos. EU569290 and EU569291, respectively) were 99 to 100% identical to the corresponding region in a published TRV sequence (GenBank Accession No. AF055912). A 396-bp fragment was amplified from UR tubers and sequence data (GenBank Accession No. EU569292) indicated a unique 63 nucleotide sequence was substituted for a 129 nucleotide sequence spanning residues 227 to 357 of the 463-bp amplicon from the RB TRV isolates. Seven fragments were sequenced from different UR tubers and the 396-bp fragment was identical among them. The sequence outside the substituted region had 92% identity to the published TRV sequence. Amplification of the full-length TRV RNA2 using primers 179/180 located in the 5′ and 3′ untranslated regions (2) was successful for 28 and 0% of the RB and UR samples, respectively, suggesting that the RNA2 is not present in these strains or has undergone significant mutation. TRV-infected sap from both potato cultivars was mechanically transmitted to tobacco cv. Samsun NN and these plants subsequently tested positive for TRV by ELISA using ATCC antiserum PVAS 820. Ninety tubers exhibiting mild to severe symptoms of TRV were planted in the greenhouse. Each tuber was bisected laterally; necrotic tissue was removed from one half of the tuber and tested for the presence of TRV using RT-PCR protocols described above for RNA1. The remaining half was bisected horizontally and both sections were planted. Foliage from each emerged plant was subsequently also tested by RT-PCR for TRV RNA1. All RB tubers from Wisconsin tested positive for TRV, but only 7 of 24 emerged plants tested positive. Only 72% of the UR tubers and 4 of 25 emerged plants tested positive. TRV has been confirmed in California, Colorado, Florida, Idaho, Michigan (1), Oregon, and Washington. To our knowledge, this is the first report of corky ringspot in potato caused by TRV in Minnesota and Wisconsin. References: (1) W. W. Kirk et al. Plant Dis. 92:485, 2008. (2) S. A. MacFarlane. J.

Abstract:

Aerial stem rot of potato (Solanum tuberosum), also known as bacterial stem rot, is often caused by the pectolytic bacteria Pectobacterium (Erwinia) carotovorum subsp. carotovorum, P. atrosepticum, or Dickeya spp. (3). A survey was carried out in August 2008 in ‘Russet Burbank’ potato fields exhibiting aerial stem rot symptoms in the Columbia Basin of Washington State. One bacterial strain isolated during the survey, PwO405, exhibited pectolytic ability on crystal violet pectate (CVP) agar and potato slices and failed to grow at 37°C, but physiological tests did not conclusively distinguish the bacterium as P. atrosepticum (1). The bacterium was positive for ONPG, N-acetylglucosaminyl transferase, gelatin liquefaction, and acid production from D-galactose, lactose, melibiose, raffinose, citrate, and trehalose. The bacterium was negative for indole production and acid production from maltose, α-methyl-D-glucoside, sorbitol, D-arabitol, inositol, inulin, and melezitose. Molecular identification of the bacterium was performed with 16S rRNA, aconitase (acnA), and malate dehydrogenase (mdh) coding sequences as previously described (2,4). Partial sequences of 16S rRNA (1,408 bp) and acnA (412 bp) genes (GenBank Accession Nos. JQ723958 and JQ723959, respectively) exhibited 99% shared identities with P. wasabiae strain WPP163, while the mdh sequence (435 bp) (GenBank Accession No. JQ723960) exhibited 100% shared identity with mdh sequences from three P. wasabiae strains (NZEC9, NZEC10, and NZEC8974). Maximum parsimony analysis using concatenated acnA and mdh sequences from this study and Pectobacterium sequences previously deposited in GenBank (2,4) clustered strain PwO405 with other P. wasabiae strains. Three 7-week-old ‘Russet Norkotah’ potato plants were wound-inoculated by inserting a sterile 23 gauge needle just above a central leaf axil at a depth of 1 mm. A 10-μl drop of inoculum (104 CFU) was placed on the wound. Plants were exposed to a 24-h leaf wetness period (90 to 100% RH in a mist chamber) and lesions were measured. All three inoculated plants exhibited aerial stem rot symptoms similar to those observed in the field, including brown water-soaked lesions that spread acropetally and basipetally. Upon drying, the lesions became shriveled and turned dark brown to black. Some plants exhibited hollowing of the stems and unilateral wilt on the side of the lesion. Symptoms were not observed on water-inoculated controls. The bacteria that were reisolated into pure culture from all three inoculated stems caused pitting on CVP and exhibited the same morphology as the original culture and were confirmed as P. wasabiae using 16S rRNA, acnA, and mdh coding sequences, fulfilling Koch's postulates. Stem rot ability of the bacterium was also confirmed on four potato cultivars: ‘Ranger Russet,’ ‘Russet Burbank,’ ‘Russet Norkotah,’ and ‘Umatilla Russet’ by wound-inoculating six single-stem plants of each cultivar as described above. To our knowledge, this is the first report of aerial stem rot of potato caused by P. wasabiae in Washington State. References: (1) S. De Boer and A. Kelman.

Abstract:

Este ensayo fotográfico se basa en proponer, a partir de las esculturas de Berrocal, una serie de analogías en formato fotográfico. El conjunto revela y explora una dimensión erótica del universo de Berrocal conectando las obras con prácticas vinculadas al bondage y a la dominación. Cuando revisamos la bibliografía fundamental* sobre Berrocal descubrimos que la mayoría de estudios y análisis sobre su obra están, en parte, atrapados por el gran truco del artista, i.e. la excelente (obscena) capacidad de esconder secretos eróticos justo delante de nuestros ojos. La propuesta nos introduce en uno de los infinitos caminos de regreso al interior de la obra del artista eludiendo las ilusiones matemáticas y científicas del gran mago Berrocal.

Abstract:

En febrero de 2020 fui invitado a visitar la casa, el taller y el museo de Miguel Berrocal en Villanueva de la Algaida. Recuerdo la magnífica decoración de la casa, el emblemático edificio que alberga el museo, la grata sobremesa con sus hijos… Pero lo que más me sorprendió fue el taller del artista. Allí pude sumergirme en la obra de Miguel Berrocal, en sus técnicas de trabajo, en el concepto de reproducción, en su filosofía estética. Allí pude tocar sus esculturas, jugar con sus obras desmontables, embeberme de la compleja mirada que tenía sobre el mundo. Y allí, en un rincón cercano a la biblioteca (donde se atesoran los libros que usó en vida Miguel Berrocal, y sus escritos, láminas e ilustraciones, e incluso, un poema dedicado a una de sus Meninas por Rafael Alberti), leyendo algunos textos y artículos, ausente del mundo y en diálogo íntimo con el lugar y con el artista, descubrí su famoso Codex Berrocalensis, una serie de acuarelas acompañadas por unas reflexiones de índole filosófica escritas por su propia mano. En estas acuarelas, estos textos, se sintetiza una parte muy importante del pensamiento estético de Miguel Berrocal. Tal fue el impacto que provocó en mí su lectura, que durante meses estuve rumiando sus postulados hasta desvanecerme en ellos. El resultado de esta experiencia ultrasensorial ha sido la escritura de una serie de poemas en los que entro en diálogo con los textos y reflexiones que Miguel Berrocal dejó plasmados en el Codex Berrocalensis.

Abstract:

En una de las múltiples visitas al estudio taller de Miguel Berrocal en Villanueva de Algaidas (sede de la Fundación Escultor Berrocal para las Artes) que hemos tenido el privilegio de realizar a lo largo de 2019-2020 –con el pretexto de la preparación de este número–, tuvo lugar uno de esos encuentros fortuitos que el estudio taller propicia. De repente me reconocí inmerso en una especie de relato de Vila - Matas. Imaginé una escena tan improbable y singular, como surrealista: visualicé en la entrada de la Villa del Negrar a un impoluto e impecable dandi, de traje oscuro y singular bombín. Un paraguas en una mano y una pequeña maleta en la otra. Podía reconocer la misma corbata de flores que aparece en el retrato que hizo S. Schapiro en 1965 de René François Ghislain Magritte con su fascinante Golconda(1953) como fondo. Aunque lo mas llamativo esta vez no sería ni el bombín ni la corbata, sino un florido botín de vivos colores. Aunque solo uno, el derecho. En el pie izquierdo se dejaba ver un calcetín listado. El pintor surrealista, “el jinete perdido”, esperaba de tal guisa ser recogido en coche por su marchante Alexander Yolas. Para quizás emprender el largo viaje de vuelta a Schaerbeek tras haber verificado el proceso de fundición de unos moldes en cera de su obra, cuya supervisión Yolas había encomendado a Berrocal en 1967. El párrafo anterior intenta describir[1]y hacer emerger –confiando en el potencial de la écfrasis[2]– una imagen muy concreta, aunque ésta no sea mas que unaconstrucción imaginaria. Pero eso sí, una imagen que fue provocada e inducida por un objeto en particular. Se ponía así de manifiesto todo su potencial afectivo/efectivo, o como diría Alfred Gell (2016), su ‘agencia’. Este objeto es, precisamente, el botín cuya fotografía ocupa la portada de este número:La chaussure de Magritte (López, 2019).Un objeto que, a priori, poco o nada tendría que ver con el universo de Berrocal, salvo por el hecho de que este zapato en concreto, este supuesto botín de Magritte, se encontraba cuidadosamente dispuesto en una estantería de su estudio. (Continuar leyendo) [1]Entendiendo que un texto solo puede describir lo que vemos en una imagen, pero en ningún caso puede llegar a representarlo (Goodman, 1976). [2]Mitchell en su conocida Teoría de la Imagen (2009) analiza lo que el mismo denomina “la fascinación del problema de la écfrasis”, e identifica tres estadios de la misma: “el miedo a la écfrasis”, “la esperanza ecfrásica” y por último “la indiferencia a la écfrasis” (pp. 138-139). Para posicionarse finalmente –contra Goodman– de forma explícita a favor de la última posición, asumiendo que: “(…) no existe ninguna diferencia esencial entre los textos y las imágenes y, por tanto, no hay ningún cisma que deba quedar superado por estrategias ecfrásticas especiales.” (p.144). [Véase la discusión sobre esta posición en Kurazynska y Cabrera (2020)].

Abstract:

Este es un proyecto artístico digital realizado por Chico López en la plataforma Instagram entre 2016 y 2018, el creador aborda cuestiones surgidas en relación a la práctica artística y las redes sociales. Experimenta con imágenes fotográficas digitales manipuladas con las aplicaciones: Layout e Instagram. Activa así experiencias pictóricas, que permiten formular lecturas sensibles a partir de la visibilidad de la superficie digital al simular estas aplicaciones texturas que tradicionalmente han sido proporcionadas por la fluidez de la pintura, usando procedimientos digitales encontrados en las limitaciones técnicas de las herramientas de la aplicación Layout. El autor desarrolla experiencias estéticas y artísticas encubiertas por el contexto de la red social empleada.

Abstract:

Ante la proposición de una escultura del vacío en la obra de Miguel Berrocal, estudiamos las influencias del pensamiento oriental en el trabajo del escultor y profundizamos en las referencias a través de las que se filtraría en su trabajo el interés por esta noción escurridiza que escapa al entendimiento occidental y a su expresión plástica.Nos acercamos a quien fuera su maestro, Ángel Ferrant; al introductor del hueco en la escultura británica del siglo XX, Henry Moore; y a sus coetáneos, Oteiza y Chillida, máximos representantes de una escultura del vacío en nuestro país. El cierre de esta problemática, para asumir otros retos, supone en Berrocal la clausura y abandono de esta cuestión irresoluble. Con esta liquidación deja de lado un desafío superior que no volverá a afrontar de manera comprometida, aunque se filtrará para siempre en su manera de entender el espacio escultórico.
