Abstract:
Ediacaran fossils from the southwestern Great Basin may help constrain regional Vendian-Cambrian biostratigraphy and provide biogeographic links between facies in this region and elsewhere. Locally, trace fossils suggest the Vendian-Cambrian boundary occurs within or below the upper third of the lower member of the Wood Canyon Formation. Ediacaran soft-bodied and tubular fossils, including the frondlike fossil Swartpuntia and tubular, mineralized or agglutinated fossils similar to Archaeichnium Cloudina Corumbella, and Onuphionella occur in the lowermost Wood Canyon Formation. Discoidal forms referred to Nimbia occur in both the lowermost Wood Canyon Formation and the underlying strata of the Stirling Quartzite. These fossils occur directly below Lower Cambrian trace fossils, including Treptichnus pedum, and confirm the persistence of the Ediacaran biota to near the base of the Cambrian. These faunas may also help strengthen previously proposed correlation schemes between the two main facies belts of the southwestern Great Basin (the Death Valley and White-Inyo facies), because a nearly identical Vendian-lowest Cambrian succession of faunas occurs in both regions. Lastly, lack of cosmopolitan Ediacaran faunas in these strata suggests a paleobiogeographic link between the southwestern U.S. and southern Africa in Vendian time.

Abstract:
Abstract A significant, convectively induced windstorm known as a derecho occurred over parts of Utah, Wyoming, Idaho, and Colorado on 31 May 1994. The event was unusual in that it occurred not only in an environment of relatively limited moisture, but also one with a thermodynamic profile favorable for dry microbursts in the presence of moderate midtropospheric flow. The development and evolution of the severe wind-producing convective system is described, with emphasis on the synoptic and mesoscale features that may have contributed to its strength and maintenance. A very similar derecho that affected much the same region on 1 June 2002 is more briefly introduced. Questions are raised regarding the unique nature of these events and their potential utility in achieving an increased understanding of the mechanics of derecho-producing convective systems in more moisture-rich environments.

Abstract:
We used data from 20 enzyme loci to test hypotheses concerning the population genetic structure of Douglas-fir (Pseudotsugamenziesii (Mirb.) Franco) in the Great Basin relative to the southern Rocky Mountains of Utah. Detailed macrofossil data from wood rat (Neotoma) middens indicate that P. menziesii was absent from the central and northern Great Basin during the last glacial (20 000–12 000 years before present), but has recolonized several of the "island" mountain ranges of that region during the past 10 000 years by long-distance dispersal from populations on the southern Rocky Mountain "mainland". The genetic consequences of rare, chance dispersal events should be a reduction in levels of genetic diversity on Great Basin montane islands and more diversity among island populations relative to the Rocky Mountain mainland. We found moderate overall reductions in the level of polymorphism (65 vs. 85%), numbers of alleles per polymorphic locus (2.69 vs. 2.82), and gene diversity (0.113 vs. 0.141) in Great Basin P. menziesii relative to P. menziesii from the Rocky Mountain mainland. Within-population estimates of allozyme diversity, as well as relative partitioning of that diversity among populations of each region, differed to a lesser extent between island and mainland regions. Founder effects and genetic drift thus appear to have had a minor role in shaping the present-day genetic structure of Great Basin P. menziesii populations.

Abstract:
Social vulnerability refers to how social positions affect the ability to access resources during a disaster or disturbance, but there is limited empirical examination of its spatial patterns in the Great Lakes Basin (GLB) region of North America. In this study, we map four themes of social vulnerability for the GLB by using the Center for Disease Control’s Social Vulnerability Index (CDC SVI) for every county in the basin and compare mean scores for each sub-basin to assess inter-basin differences. Additionally, we map LISA results to identify clusters of high and low social vulnerability along with the outliers across the region. Results show the spatial patterns depend on the social vulnerability theme selected, with some overlapping clusters of high vulnerability existing in Northern and Central Michigan, and clusters of low vulnerability in Eastern Wisconsin along with outliers across the basins. Differences in these patterns also indicate the existence of an urban–rural dimension to the variance in social vulnerabilities measured in this study. Understanding regional patterns of social vulnerability help identify the most vulnerable people, and this paper presents a framework for policymakers and researchers to address the unique social vulnerabilities across heterogeneous regions.

Full text
Abstract:
The Great Artesian Basin (GAB) underlies a vast, mainly arid, region where most of the indigenous biota are not dependent upon surface water. In contrast, an important minority is dependent on refuges such as mound springs and their associated wetlands. In some parts of the GAB, such as western New South Wales, many springs have either ceased to flow, or are now barely detectable, because the proliferation of artesian waterbores has reduced groundwater pressures. Because of the rarity of species endemic to mound springs, and the damage they have suffered since pastoral settlement, emphasis should be directed towards conservation and possible rejuvenation of these ecosystems. Provision of artificial sources of water allows more widespread grazing by livestock, larger native and feral herbivores, thereby posing threats to native plants and animals that do not use the water. Because of the proliferation of artificial waters and the grazing they allow, terrestrial grazing-sensitive species now appear to be confined to tiny patches in the landscape. Some nature reserves within the GAB retain numerous artificial sources of water. Most of these should be closed over time to reduce negative impacts on grazing-sensitive plants and animals, especially where these species are inadequately protected elsewhere. In those regions where the ratio of artificial to natural waters is still low, consideration should be given to balancing provision of water for livestock with conservation of biological diversity, by maintaining a patchwork of areas remote from water. In regions where the density of artificial waters is high, conservation of biodiversity on freehold and leasehold lands might be enhanced with a mix of approaches accommodating the needs of the biota and the aspirations of landholders, tailored according to land type and condition. Key words: Great Artesian Basin, biological diversity, mound springs, refuges, rare biota, grazing impact, conservation management, groundwater.

The current interpretation of post-Archaic culture history in the northeastern Great Basin is that the Great Salt Lake regional variant of the Fremont culture arose from an Archaic base and is distinguished by two types of unpainted pottery, Great Salt Lake Gray and Promontory Gray. Seen as ethnically unrelated to the Fremont, the subsequent Shoshoni culture is marked by one type of unpainted pottery, Shoshoni Ware. These types are said to be characterized by distinct combinations of attributes, but close examination reveals that what these combinations are, and how they distinguish each type, has not been clearly described in the archeological literature. In this study, I re-analyze fragments of undecorated pottery previously classified as Great Salt Lake Gray, Promontory Gray, and Shoshoni Ware. Through rigorous and replicable methods, five major attributes found in every sherd are examined: wall thickness, exterior surface color, temper material, temper size, and technique of vessel shaping. This analysis showed that previous identifications of pottery attributes were partially or entirely erroneous. Every attribute measured demonstrated the same essential pattern: Great Salt Lake Gray had a wide range of variation, and Promontory Gray and Shoshoni Ware fell within this range. Further, except for one form of temper material, Promontory Gray and Shoshoni Ware shared the same attributes with one another. Ethnographic evidence is also presented that links late prehistoric pottery to that of the historic Shoshoni, confirming a single unbroken pottery tradition in the Great Salt Lake region. I conclude that the evidence of this study does not support the concept of two unrelated pottery traditions (Fremont and Shoshoni) in the Great Salt Lake region. Based on this work, much of the traditionally conceived post-Archaic culture history of this region must be reevaluated.

Abstract:
Native and introduced grass and shrub species are grown for seed production in the Great Basin region of the United States. The purpose of this research is to evaluate the profitability and risk associated with the production of five different species of grasses and shrubs which are used in rehabilitation following wildfires. Enterprise budgets are constructed for both the establishment and production years. Returns above operating costs are compared to other crops produced in the same region. Production and market risks are discussed. Returns and risks are evaluated using an expected value model which compares risk and return between species, as well as risk and return for seven different crop combinations on a simulated 400-acre farm. All five species evaluated are found to be more profitable than other crops grown in the region. However, there are many production and market factors which must be carefully considered prior to investment in grass and shrub seed production.

La carte en courbe de differenciation est discutee : le contenant et le contenu sont analyses; la stabilite de l'information sturcturale et de l'image cartographique lors d'une reduction de la maille ou de l'echelle est abordee. Ainsi la differenciation pedologique est marquee par le transfert de l'argile. Le profil d'eluviation-illuviation est d'autant plus lateral et net que la pente est forte; l'hydrochimie se declenche a l'aval quand la porosite est colmatee par l'argile illuviale. En revanche, la distribution des horizons organiques superficiels est regie par l'erosion. La stabilite de cette couverture epaisse sous des conditions climatiques mediterraneennes agressives est reliee au developpement d'une importante microagregation. L'etude de la stabilite et de la constitution des differentes classes d'agregats montre le role du fer amorphe et de sa liaison avec les acides humiques dans le developpement et la perennite de cette microagregation. Le fer provient en grande partie de l'alteration des chlorites qui aboutit en meme temps a la formation de mineraux a comportement intergrade dont les cales interfoliaires sont essentiellement ferriferes. Deux voies d'approche ont ete suivies pour l'etude de ces mineraux : -l'extraction chimique des amorphes externes et internes et le suivi du comportement a la diffraction rx des argiles traitees : - l'etude de l'alteration des chlorites ferriferes par voie microanalytique

Certaines régions offrent des perspectives très intéressantes, aussi bien sur le plan de la coopération transfrontalière que des PPP. C’est notamment le cas de la région francophone de l’Afrique des Grands Lacs.

Abstract:
Ground water is a critical element of the ecosystem in the Great Lakes Basin. It is an integral component of a dynamic hydrological system that is the lifeblood for this region's remarkable natural diversity. It is also an important human resource. Unfortunately, intensive ground water withdrawals are resulting in negative consequences that are often hidden from view but which are causing social conflicts and environmental degradation. This thesis considers the failure of courts and governments to implement laws for allocating ground water rights according to hydrological reality and the collective interests of affected communities. Legal mechanisms are rooted in the nineteenth and early twentieth centuries. Despite rapid growth and the considerable pressure now exerted on ground water resources, courts and governments continue to allow, and even encourage unrestricted ground water withdrawals. The underlying ideology of state institutions within the Basin is contributing to the systematic undervaluation of environmental and long term interests of present and future generations. A reinvigorated concept of sustainability, one that is based on the ideals of deliberative democracy, would better represent these interests in decisions concerning the allocation of ground water. Through the process of ground water allocation planning, decision-making can be guided into a preventative and community-oriented approach that more accurately reflects the long term interests of the Basin.

Abstract:
Globally, drinking water supplies are unique as a result of differing water storage capacities, climate, regional geology, treatment types and anthropogenic effects. Traditionally, middle to large sized waterbodies have dominated ecological studies about water supplies. However, small water storages are used to supply a significant portion of human water demands, particularly in geographically isolated locales. Despite this, there is a dearth of information on small waterbodies that are more susceptible to environmental change during natural rainfall events or anthropogenic impacts such as contamination. This study investigated Baffle Creek, a small relatively unmodified, unregulated subtropical ephemeral catchment located on Australia’s eastern seaboard, and the southernmost catchment to drain into the Great Barrier Reef Marine Park. The aim was to identify potential health, treatment and aesthetic risks, with particular reference to metals and phytoplankton risk in the drinking water supply. Data collection was performed over 28 months including two wet and two dry seasons. The study consisted of five surface water sites and two supply chain infrastructure sites. Water quality variables and phytoplankton concentrations were assessed monthly. Metal and nutrient concentrations were quantified from water and soil samples collected quarterly. Analysis of Similarity (ANOSIM) results indicated that water quality variables within the upstream, midstream and downstream sections of the catchment were statistically different and thus likely to pose different risks to the water supply. In the upstream waters, risks included pH reduction combined with an increase in colour (organic matter), whereas the dominant risk in the downstream sections was elevated conductivity. A conceptual model was created to facilitate visualisation of differences between the sections of the catchment and in turn, aid with management decisions. The hydrogeochemistry of Baffle Creek was predominantly driven by rain events. Following a flushing event, concentrations of dissolved aluminium and nitrate increased in the surface and drinking water, whereas manganese and ammonia were undetectable in the drinking water and occurred only in small concentrations in the surface waters. In contrast, when rainfall events occurred without an associated flush, manganese, iron and ammonia concentrations increased in the drinking water. The hydrochemistry of manganese and iron in the supply chain infrastructure was positively correlated with ammonia concentrations, and aluminium concentrations were correlated with nitrate concentrations. Currently the drinking water supply does not pose a threat in regards to chronic manganese exposure in humans; however, elevated concentrations occur periodically; and may become more problematic with climate change scenarios. Hierarchical agglomerative clustering with the addition of a similarity profile test (SIMPROF) of phytoplankton data and comparison with a principal component analysis of corresponding environmental data were used to validate the relationships between environmental gradients and variations in the phytoplankton assemblages. A biological-environmental stepwise test (BEST) was performed to assess correlations among environmental variables with the biological data, describing which changes in environmental variables were associated with the ecological composition of phytoplankton communities. The Spearman’s rank correlation between environmental conditions and phytoplankton communities was significant p < 0.05, however, weak ρ = 0.329. Variable rainfall - and therefore streamflow - led to the proliferation of genera adapted to the dynamic instream conditions, with picoplanctonic phytoplankton (Aphanocapsa and Nannochloris) being predominant in abundance and flagellated phytoplankton predominating from a bio-volume perspective (Trachelomonas, Peridinium, Cryptomonas and Euglena). There were 66 phytoplankton genera identified and from this, 10 coherent “functional groups” were statistically identified with certain environmental tolerances and sensitivities, as well as potential health, treatment and aesthetic considerations. There were 13 genera of cyanobacteria identified which may be potentially toxic, 11 phytoplankton genera that may cause treatment risk and 20 genera that may be an aesthetic risk. A novel quantitative approach was utilized for grouping of environmental variables, phytoplankton assemblages, tolerances, sensitivities and multiple-risk information to assist water managers to have a more precise understanding of the suite of risks posed by phytoplankton populations in ephemeral subtropical systems. Based on field data, a semi-quantitative risk matrix methodology was developed for use as a supplement to existing Water Safety Plans. For example, the primary risk identified for the Baffle Creek catchment was the presence of Cyanobacteria in the pre-chlorinated supply chain, specifically Limnothrix redekei. To respond to this, a preliminary proposal was suggested involving use of clean sand on the sub-surface layer of the bank filtration, complemented with biologically active sand as a surface cap. Furthermore, culturing techniques reported in this study can potentially be used to optimize assessment for L. redekei populations surrounding water extraction points. The present study provides insights as to some of the most important factors affecting the safety and palatability of drinking water from small water supplies. Furthermore, models were developed to provide managers of water treatment plants with additional information to help inform decision management and management of small water supplies, particularly in subtropical environments globally.

Abstract:
AbstractWhile the subset of introduced species that become invasive is small, the damages caused by that subset and the costs of controlling them can be substantial. This chapter takes an in-depth look at the economic damages non-native species cause, methods economists often use to measure those damages, and tools used to assess invasive species policies. Ecological damages are covered in other chapters of this book. To put the problem in perspective, Federal agencies reported spending more than half a billion dollars per year in 1999 and 2000 for activities related to invasive species ($513.9 million in 1999 and $631.5 million in 2000 (U.S. GAO 2000)). Approximately half of these expenses were spent on prevention. Several states also spend considerable resources on managing non-native species; for example, Florida spent $127.6 million on invasive species activities in 2000 (U.S. GAO 2000), and the Great Lakes states spend about $20 million each year to control sea lamprey (Petromyzon marinus) (Kinnunen 2015). Costs to government may not be the same as actual damages, which generally fall disproportionately on a few economic sectors and households. For example, the impact of the 2002 outbreak of West Nile virus exceeded $4 million in damages to the equine industries in Colorado and Nebraska alone (USDA APHIS 2003) and more than $20 million in public health damages in Louisiana (Zohrabian et al. 2004). Zebra mussels (Dreissena polymorpha) cause $300–$500 million annually in damages to power plants, water systems, and industrial water intakes in the Great Lakes region (Great Lakes Commission 2012) and are expected to cause $64 million annually in damages should they or quagga mussels (Dreissena bugensis) spread to the Columbia River basin (Warziniack et al. 2011).

Abstract:
AbstractIntegrated River Basin Management (IRBM) involves the integration of the multiple uses of water, the integration of multiple properties of water: water disaster, water resources, waterways, water environment, water ecology, water landscape and water culture, and the integration of water by space: upstream vs downstream, left bank vs right bank. The main problems of IRBM within the Lancang-Mekong River Basin includes flood disaster, navigation and its impact to basin cooperation, contradiction between development and protection, and public security in a framework of cooperation and integration. It has been a general concern for Mekong countries to manage water conservancy engineering and coordinate water supply, navigation, fishery, power generation, and water disaster management. All stakeholders put great emphasis on water conservancy engineering management in terms of basin planning, domestic and cross-border project construction, and cooperation mechanisms. In order to ensure the sustainable use of water resources, a series of continuously updated plans were proposed. Those plans set goals and provided measures for the rational and sustainable development of the resources in the basin, and meanwhile, it also put forward a mechanism to offset the adverse effects. The development of international navigation has deepened win-win cooperation, strengthened regional economic exchanges and tourism development, promoted regional prosperity among China, Laos, Myanmar and Thailand. The basin has abundant fishery resources and has the world’s third most diverse fish population, with 1,148 fish species, after the Amazon and Congo River Basins. Mekong countries have different needs for the development of fishery resources due to their different geographical locations and economic development, and thus very little cooperation in fisheries has been carried out among Mekong countries. The basin’s ecohydrological management involves environmental flow, water quality, soil erosion and sedimentation, aquatic organism and underground water protection. The current measures include enhancing monitoring, scientific assessment, rational regulation of water system, the establishment of natural reserves, and international cooperation. Climate change and construction of dams are both critical challenges faced by the basin in terms of ecohydrological management in the 21st century.

Abstract:
ABSTRACT The paleogeographic evolution of the western U.S. Great Basin from the Late Cretaceous to the Cenozoic is critical to understanding how the North American Cordillera at this latitude transitioned from Mesozoic shortening to Cenozoic extension. According to a widely applied model, Cenozoic extension was driven by collapse of elevated crust supported by crustal thicknesses that were potentially double the present ~30–35 km. This model is difficult to reconcile with more recent estimates of moderate regional extension (≤50%) and the discovery that most high-angle, Basin and Range faults slipped rapidly ca. 17 Ma, tens of millions of years after crustal thickening occurred. Here, we integrated new and existing geochronology and geologic mapping in the Elko area of northeast Nevada, one of the few places in the Great Basin with substantial exposures of Paleogene strata. We improved the age control for strata that have been targeted for studies of regional paleoelevation and paleoclimate across this critical time span. In addition, a regional compilation of the ages of material within a network of middle Cenozoic paleodrainages that developed across the Great Basin shows that the age of basal paleovalley fill decreases southward roughly synchronous with voluminous ignimbrite flareup volcanism that swept south across the region ca. 45–20 Ma. Integrating these data sets with the regional record of faulting, sedimentation, erosion, and magmatism, we suggest that volcanism was accompanied by an elevation increase that disrupted drainage systems and shifted the continental divide east into central Nevada from its Late Cretaceous location along the Sierra Nevada arc. The north-south Eocene–Oligocene drainage divide defined by mapping of paleovalleys may thus have evolved as a dynamic feature that propagated southward with magmatism. Despite some local faulting, the northern Great Basin became a vast, elevated volcanic tableland that persisted until dissection by Basin and Range faulting that began ca. 21–17 Ma. Based on this more detailed geologic framework, it is unlikely that Basin and Range extension was driven by Cretaceous crustal overthickening; rather, preexisting crustal structure was just one of several factors that that led to Basin and Range faulting after ca. 17 Ma—in addition to thermal weakening of the crust associated with Cenozoic magmatism, thermally supported elevation, and changing boundary conditions. Because these causal factors evolved long after crustal thickening ended, during final removal and fragmentation of the shallowly subducting Farallon slab, they are compatible with normal-thickness (~45–50 km) crust beneath the Great Basin prior to extension and do not require development of a strongly elevated, Altiplano-like region during Mesozoic shortening.

Abstract:
<em>Abstract.</em>—We reviewed native fish zoogeography in 22 major tributary basins of the Missouri River basin in the Great Plains geomorphic province and used island biogeographical approaches to study the influence of basin area and isolation on faunal composition. Basin area was correlated with elevation range and basin isolation was negatively correlated with annual freeze-free days. Ninety-six species were native to the tributary basins. Ninety-one were of southern (Gulf of Mexico drainage) origin. Fifty were found in four or fewer tributary basins and, except for three mountain species, were only found from the Cheyenne basin downstream. Twenty-five widespread species were either present among tributary basins during glaciation or colonized the region during recession of the continental glaciers. Sixty-six more restricted species presumably colonized more recently. Five species colonized from Pacific Ocean drainages via interdrainage connections in the Rocky Mountains. The hypothesis that variation between some closely related Great Plains fishes reflects the former presence of a prehistoric “Ancient Plains Drainage” is no longer tenable given recent geological findings, but a series of stream captures between the ancient Arkansas and Kansas basins could account for such variation. All analyses indicated that native fish faunal composition among tributary basins was heavily influenced by factors related to basin area and isolation. A presence–absence matrix of fishes by tributary basin had very high nestedness, whether ordered by basin area or basin isolation. Cluster analysis of Wilcoxon two-sample tests of individual species distributions revealed seven species groups with distinct distribution patterns. The three largest groups were most prevalent in less isolated (southern) tributary basins. A nonmetric multidimensional scaling analysis (NMDS) based on Sørensen’s index of similarity indicated that two axes (both correlated with tributary basin isolation, one correlated with tributary basin area) accounted for 95% of variance between distance in the ordination space and distance in the original <em>n</em>-dimensional space. A cluster analysis of NMDS scores identified five tributary basin groups. The five southernmost basins (Kansas to White) composed one group, and the eight basins to the north (Bad to Little Missouri) composed another. The nine northernmost basins were split into three groups, one including small basins isolated from the Rocky Mountains, another including large basins with Rocky Mountain headwaters, and the last including two basins that were mostly within the Rocky Mountains. The influence of tributary basin area on faunal composition was presumably due to increased chance of colonization, higher habitat stability, and higher habitat diversity in larger tributary basins. The influence of tributary basin isolation was presumably due to higher colonization rates and more equitable climate in southern tributary basins. Fish faunas of the Missouri River basin in the Great Plains have experienced cyclical geomorphic and climatic instability for roughly 2.8 million years and were assembled like island faunas by variable colonization and extinction rates mediated by tributary basin area and isolation. This contrasts with the highly diverse freshwater fish faunas of the Central Highlands that have differentiated through speciation within regions that have been relatively stable geomorphically and climatically for more than 38 million years.

Full text
Abstract:
Carbon dioxide (CO2) storage is a vital part of the energy transition to low emissions. The Jurassic age Precipice Sandstone of the Surat Basin in Queensland, Australia, has been investigated as a suitable reservoir for CO2 storage. The overlying Evergreen Formation is a thick, interbedded mudstone and sandstone seal, and regarded a regional aquitard. Wells have been drilled for feasibility studies, initially in CTSCo’s Glenhaven region, near Wandoan, and recently in the southern Surat Basin near the town of Moonie. Since the Precipice Sandstone is also a Great Artesian Basin aquifer, the southern region with deeper groundwater unsuitable for stock use, and minimal to stagnant flow, is likely a more suitable site. The University of Queensland has undertaken research in both potential storage regions, and more broadly across the basin, including the separate Moonie oil field. This presentation will focus on core characterisation, experimental and modelled geochemical CO2-water-rock reactions and their impacts on water quality, porosity and permeability, and the effects of gas stream impurities SOx, NOx and O2. In addition, it may touch on field studies to assess existing hydrochemistry, water quality and native greenhouse gases in the Precipice Sandstone, and in the Hutton Sandstone that overlies the Evergreen Formation.

Full text
Abstract:
The Montney Formation is a highly productive hydrocarbon reservoir with significant reserves of hydrocarbon gases and liquids making it of great economic importance to Canada. However, high concentrations of hydrogen sulfide (H2S) have been encountered during exploration and development that have detrimental effects on environmental, health, and economics of production. H2S is a highly toxic and corrosive gas and therefore it is essential to understand the distribution of H2S within the basin in order to enhance identification of areas with a high risk of encountering elevated H2S concentrations in order to mitigate against potential negative impacts. Gas composition data from Montney wells is routinely collected by operators for submission to provincial regulators and is publicly available. We have combined data from Alberta (AB) and British Columbia (BC) to create a basin-wide database of Montney H2S concentrations. We then used an iterative quality control and quality assurance process to produce a dataset that best represents gas composition in reservoir fluids. This included: 1) designating gas source formation based on directional surveys using a newly developed basin-wide 3D model incorporating AGS's Montney model of Alberta with a model in BC, which removes errors associated with reported formations; 2) removed injection and disposal wells; 3) assessed wells with the 50 highest H2S concentrations to determine if gas composition data is accurate and reflective of reservoir fluid chemistry; and 4) evaluated spatially isolated extreme values to ensure data accuracy and prevent isolated highs from negatively impacting data interpolation. The resulting dataset was then used to calculate statistics for each x, y location to input into the interpolation process. Three interpolations were constructed based on the associated phase classification: H2S in gas, H2S in liquid (C7+), and aqueous H2S. We used Empirical Bayesian Kriging interpolation to generate H2S distribution maps along with a series of model uncertainty maps. These interpolations illustrate that H2S is heterogeneously distributed across the Montney basin. In general, higher concentrations are found in AB compared with BC with the highest concentrations in the Grande Prairie region along with several other isolated region in the southeastern portion of the basin. The interpolations of H2S associated with different phases show broad similarities. Future mapping research will focus on subdividing intra-Montney sub-members plus under- and overlying strata to further our understanding of the role migration plays in H2S distribution within the Montney basin.

Abstract:
Original objectives: [a] Screen an array of chickpea and wild annual Cicer germplasm for winter survival. [b] Genetic analysis of winter hardiness in domesticated x wild chickpea crosses. [c] Genetic analysis of vernalization response in domesticated x wild chickpea crosses. [d] Digital expression analysis of a core selection of breeding and germplasm lines of chickpea that differ in winter hardiness and vernalization. [e] Identification of the genes involved in the chickpea winter hardiness and vernalization and construction of gene network controlling these traits. [f] Assessing the phenotypic and genetic correlations between winter hardiness, vernalization response and Ascochyta blight response in chickpea. The complexity of the vernalization response and the inefficiency of our selection experiments (below) required quitting the work on ascochyta response in the framework of this project. Background to the subject: Since its introduction to the Palouse region of WA and Idaho, and the northern Great Plains, chickpea has been a spring rotation legume due to lack of winter hardiness. The short growing season of spring chickpea limits its grain yield and leaves relatively little stubble residue for combating soil erosion. In Israel, chilling temperatures limit pod setting in early springs and narrow the effective reproductive time window of the crop. Winter hardiness and vernalization response of chickpea alleles were lost due to a series of evolutionary bottlenecks; however, such alleles are prevalent in its wild progenitor’s genepool. Major conclusions, solutions, achievements: It appears that both vernalization response and winter hardiness are polygenic traits in the wild-domesticated chickpea genepool. The main conclusion from the fieldwork in Israel is that selection of domesticated winter hardy and vernalization responsive types should be conducted in late flowering and late maturity backgrounds to minimize interference by daylength and temperature response alleles (see our Plant Breeding paper on the subject). The main conclusion from the US winter-hardiness studies is that excellent lines have been identified for germplasm release and continued genetic study. Several of the lines have good seed size and growth habit that will be useful for introgressing winter-hardiness into current chickpea cultivars to develop releases for autumn sowing. We sequenced the transcriptomes and profiled the expression of genes in 87 samples. Differential expression analysis identified a total of 2,452 differentially expressed genes (DEGs) between vernalized plants and control plants, of which 287 were shared between two or more Cicer species studied. We cloned 498 genes controlling vernalization, named CVRN genes. Each of the CVRN genes contributes to flowering date advance (FDA) by 3.85% - 10.71%, but 413 (83%) other genes had negative effects on FDA, while only 83 (17%) had positive effects on FDA, when the plant is exposed to cold temperature. The cloned CVRN genes provide new toolkits and knowledge to develop chickpea cultivars that are suitable for autumn-sowing. Scientific & agricultural implications: Unlike the winter cereals (barley, wheat) or pea, in which a single allelic change may induce a switch from winter to spring habit, we were unable to find any evidence for such major gene action in chickpea. In agricultural terms this means that an alternative strategy must be employed in order to isolate late flowering – ascochyta resistant (winter types) domesticated forms to enable autumn sowing of chickpea in the US Great Plains. An environment was identified in U.S. (eastern Washington) where autumn-sown chickpea production is possible using the levels of winter-hardiness discovered once backcrossed into advanced cultivated material with acceptable agronomic traits. The cloned CVRN genes and identified gene networks significantly advance our understanding of molecular mechanisms underlying plant vernalization in general, and chickpea in particular, and provide a new toolkit for switching chickpea from a spring-sowing to autumn-sowing crop.
