Streszczenie:
In this paper Canadian Yukon Cougar Optimization Algorithm is applied to solve the power loss lessening problem. Natural deeds of Canadian Yukon Cougar are imitated to model the Canadian Yukon Cougar optimization algorithm. Both male and female Canadian Yukon Cougar switch their positions with reference to the conditions. In the initial population superiority and Migrant classification are done. For each Canadian Yukon Cougar fitness value computed. For superiority matured male Canadian Yukon Cougar fight with other male Canadian Yukon Cougars. Succeeded male will be dominant and defeated male Canadian Yukon Cougars will become as Migrant Canadian Yukon Cougars. In Canadian Yukon Cougar population balance will be there at end of iterations, the amount of existing Canadian Yukon Cougar will be controlled. With reference to the Utmost allowed number of every gender in Migrant Canadian Yukon Cougar; the smallest amount fitness value possessed by Migrant Canadian Yukon Cougar will be removed. Rightfulness of the Canadian Yukon Cougar Optimization Algorithm is corroborated in IEEE 30 bus system (with and devoid of L-index). Actual power loss lessening is reached. Proportion of actual power loss lessening is augmented

Streszczenie:
Ecotones are gradients of change between expanses of similar species composition. These regions often mark co-occurring range limits for several species, and thus are ideal for elucidating ecological and biogeographical phenomena. The forest to tundra transition (FTT) is one of the world's most prominent ecotones, but remains poorly studied especially with regard to vertebrate species occurrence. Vertebrate diversity, ecological structure and resource selection were characterized across the Yukon FTT using diversity metrics, ordination, hierarchical clustering, and resource modeling. The FTT represents an abrupt drop in vertebrate species richness within the more gradual, continental scale diversity gradient. Despite the patchiness and complexity in vegetative structure over this ecotone, the terrestrial vertebrate community is divisible into boreal, taiga, and tundra compartments. Most species conform to resource associations reported closer to the core of their range, generating remarkably consistent habitat and species associations despite a complex patchwork of contrasting habitat types.

This study utilised U-Pb geochronology, and 40Ar/39Ar and (U-Th)/He thermochro-nology to delineate arc magmatism, metamorphism, and exhumation of the pericratonic Yukon-Tanana terrane in the McQuesten map area of west-central Yukon, Canada. SHRIMP U-Pb ages delineate Mid to Late Paleozoic arc magmatism and fit key units into the regional lithotectonic framework of the terrane. The juxtaposition of unmetamorphosed and predomi-nantly undeformed Devono-Mississippian rocks in the northwest of the study area with polydeformed and up to amphibolite facies metamorphosed rocks in the southwest suggests a crustal-scale discontinuity, the Willow Lake fault, bounds the two domains. The asymmetric distribution of 40Ar/39Ar ages across the fault suggest it is extensional, and was active in the Early Jurassic. Zircon (U-Th)/He ages delineate erosion of rocks in the northwest through the upper crust during the Late Triassic and Late Jurassic to Early Cretaceous followed by Mid-dle Cretaceous erosion of the southwestern domain and possibly fault reactivation.

Streszczenie:
The diversity and zoogeography of Diptera (Brachycera) of disjunct xeric grasslands in the southern Yukon were studied. Over 20,000 flies were collected representing 32 families and 213 species. In terms of abundance, the predacious guild dominated (54% of total specimens) due mostly to the family Chamaemyiidae which represented 45% of all specimens. In terms of diversity, the phytophagous and parasitoid guilds were dominant (25.5% of total species each). The most diverse families were Agromyzidae (32 species), Chloropidae (31 species), Tachinidae (23 species) and Pipunculidae (20 species). Thirty-four undescribed species were collected and 58 species were recorded for the first time in the Yukon. Zoogeographic analysis indicates that the Diptera fauna of these grasslands is dominated by widespread Nearctic or Holarctic species, but the fauna also includes southern grassland species with disjunct distributions, and species endemic to Beringia. The presence of endemic and disjunct species suggests that these grasslands were present in Beringia during the Wisconsinan and acted as a refugium for grassland Diptera.

This secondary data analysis used a cross-sectional survey of 1771 Yukon First Nations, Dene/Metis, and Inuit women. The aims were to evaluate access to traditional food (TF) and market food (MF), identify perceived advantages of TF and MF, and explore under-studied characteristics of FS in Arctic Canada. Results indicate considerable regional variation in ability to afford adequate food, varying between 26 and 58%. Similarly, regional variation was reflected in the percentage of women who had access to hunting or fishing equipment. Participants described culturally relevant FS indicators: food needed to be natural, fresh, tasty, varied, healthy, safe, accessible, and convenient. Between 10 and 38% of participants noticed recent changes in the quality or health of TFs. Caribou, moose, and seal were popular TFs and considered particularly healthy. This study emphasizes the importance of TF for Arctic indigenous women's FS and the dynamic nature of FS in this population.

Streszczenie:
Arsenic Ridge is located in the northwestern part of the Lost Horses batholith, Syenite Range, Yukon Territory. This area is within the Omineca Crystalline Belt of the Canadian Cordillera. North American miogeoclinal rocks of the upper Precambrian to Lower Cambrian Grit Unit were northwardly thrust onto Ordovician to Silurian Road River Formation during the Late Triassic to Early Jurassic arc-continent collision. Small mid-Cretaceous (83 to 100 Ma, K-Ar on biotite), epizonal felsic intrusions were emplaced in radiogenic Sr-enriched metasedimentary rocks of the ancient continental margin (pericratonic sedimentary prism). The mid-Cretaceous (syenite phase, 87+3 Ma, K-Ar on biotite; granite phase, 95+3 Ma, K-Ar on biotite) Lost Horses batholith is a circular, S-type, composite pluton within the Selwyn Basin. The Selwyn Basin is an epicontinental trough partially bounded on the west by the Cassiar Platform and on the east and northeast by carbonate rocks of the MacKenzie Platform. S-type plutons are a product of Hercynotype arc-continental collisional tectonics. The zoned intrusive rocks along Arsenic Ridge, from core to rim, have been classified as tourmaline orbicular granite, granite, quartz syenite and syenite. With increasing SiO₂ : (1) the major elements--Al₂O₃ , FeO, MgO, CaO, TiO₂, MnO and P₂O₅--tend to decrease,(2) trace elements--Zr, V, Sr, Ni, and Ba--are characterized by extreme depletions, and (3) the trace element, Rb, is slightly enriched. The syenite is alkaline whereas the quartz syenite, granite, granite dyke, and tourmaline orbicular granite are sub-alkaline. Magmatic differentiation of the pluton is demonstrated by a decreasing trend of (Na₂O + K₂O) and TiO₂ with increasing SiO₂, and by an increasing Rb content with a decrease in Ba and Sr. The estimated partial pressure of water during formation of the Lost Horses granite melt is broadly estimated as >10 kbar. Electron microprobe traverses across orthoclase megacryst cores and rims identified a concentration of albite lamellae in the rim and barium, strontium and calcite rich cores. The latter is indicative of a melt undergoing progressive depletion of barium by fractional crystallization. The age of the batholith is early Late Cretaceous, approximately 97 Ma. This was determined from early Late Cretaceous dates of 95+3 Ma from K-Ar on biotite and 88+4 Ma from K-Ar on a hornblende, and a late Early Cretaceous date of 101+6 Ma from a whole rock-mineral (biotite, hornblende, total feldspar) Rb-Sr isochron. Initial strontium ratios for the granitic rocks along Arsenic Ridge are about 0.712 suggesting that radiogenic strontium was derived mainly from melting and/or assimilation of old sialic crust during magma genesis. The model Rb-Sr age, TUR, for the granitic rocks on Arsenic Ridge is 238 Ma. This indicates that a dominantly upper mantle source is unlikely. Pb-Pb isotope ratios for the zoned plutonic rocks, the surrounding sediments and the ore mineral separates plot between the pericratonic and Bluebell curves (from 0 Ma to 140 Ma mixing lines) indicating that the lead is a mix of upper crust and lower crust sources. Lead sulphide analyses from the Zeta prospect, Tombstone Range and the Keno-Galena Hill areas are indistinguishable from the feldspar rock lead. This shows that the lead source for these vein deposits is the surrounding plutons and not the surrounding sedimentary rocks. The least radiogenic lead has a model age of about 100 Ma. Nd/Sm and Nd analyses indicate that Arsenic Ridge granitic rocks were derived from, or assimilated, old crustal rocks whose Sm/Nd had been lowered at the time of separation from CHUR. Nd ratios for the granite and the feldspar megacrysts are all very close to 0.51210. The model Sm-Nd age, TDM , for a granite along Arsenic Ridge is 1.26 Ga. Approximate percentages of continental crust and mantle incorporated in the melt were calculated. If the contamination is upper crustal in origin then there was a maximum of 30% mantle incorporated in the melt. No mantle component is needed if the contamination source is lower crust. However, since granite ¹⁴³Sm/¹⁴⁴Nd ratios are close to the average continental crust ratio, the origin is upper crust with a small mantle component. ¹⁴³Nd/¹⁴⁴Nd and ⁸⁷Sr/⁸⁶Sr ratios for the granitic rocks from the Lost Horses batholith plot in the Phanerozoic quadrant of Faure (1986) and are similar to values from the Sierra Nevada batholith. Epsilon values of Nd and Sr suggest the granite is S-type which agrees with the field, petrographic and chemical evidence. The granite plots within the field for miogeoclines as determined by Farmer and DePaolo (1983 ). The Zeta tin - silver greisen vein prospects lie in both the Ordovician - Silurian metasediments of the Road River Group at the northeastern contact, and in the zoned, mid-Cretaceous Lost Horses batholith. Mineralization on the property occurs in two forms: (1) cassiterite bearing greisen veins in hornfelsed quartzite, and (2) greisen veins (sulphide and quartz with minor tourmaline, and tourmaline and quartz with minor sulphide in granitic rocks). K-Ar muscovite dating of the sericitic cassiterite greisen (87.0+3.0 Ma), indistinguishable from the K-Ar biotite date for the syenite phase of the batholith (86.8+2.7 Ma), establishes a genetic relationship between the two. The following four-stage model describes the evolution of the Lost Horses batholith: stage 1, initial melting, stage II, melt accumulations and assimilation, stage III, diapiric rise and chemical differentiation (fractional crystallization), and stage IV, magmatic hydrothermal. This last stage generated tin-silver vein and greisen mineralization. The source for this lithophile mineralization and associated S-type granitic rock is dominantly from a sialic clastic wedge with upper crustal geochemical characteristics.

Streszczenie:

The St. Cyr klippe hosts well preserved to variably retrogressed eclogites found as sub-meter to hundreds of meter scale lenses within quartzofeldspathic schists in the Yukon-Tanana terrane, Canadian Cordillera. The St. Cyr area consists of structurally imbricated, polydeformed, and polymetamorphosed units of continental arc and oceanic crust. The eclogite-bearing quartzofeldspathic schists form a 30 by 6 kilometer thick, northwest-striking, coherent package. The schists consist of metasediments and felsic intrusives that are intercalated on the tens of meter scale. The presence of phengite and Permian age zircon crystallized under eclogite facies metamorphic conditions indicates that the eclogite was metamorphosed in situ with its quartzofeldspathic host.

I investigated the metamorphic evolution of the eclogite-facies rocks in the St. Cyr klippe using isochemical phase equilibrium thermodynamic (pseudosection) modeling. I constructed P-T pseudosections in the system Na2O-K2O-CaO-FeO-O2-MnO-MgO-Al2O 3-SiO2-TiO2-H2O for the bulk-rock composition of an eclogite and a host metatonalite. In combination with petrology and mineral compositions, St. Cyr eclogites followed a five-stage clockwise P-T path. Peak pressure conditions for the eclogites and metatonalites reached up to 3.2 GPa, well within the coesite stability field, indicating the eclogites reached ultrahigh-pressure conditions. Decompression during exhumation occurred with a corresponding temperature increase.

SHRIMP-RG zircon dating shows that the protolith of the eclogites formed within the Yukon-Tanana terrane during early, continental arc activity, between 364 and 380 Ma, while the metatonalite protolith formed at approximately 334 Ma, during the Little Salmon Cycle of the Klinkit phase of Yukon-Tanana arc activity. Both the eclogites and the metatonalites were then subducted to mantle depths and metamorphosed to ultrahigh-pressure conditions during the late Permian, between 266 and 271 Ma. The results of our study suggest portions of the Yukon-Tanana terrane were subducted to high-pressure and ultrahigh-pressure conditions. This is the first report of ultrahigh-pressure metamorphism in the accreted terranes of the North American Cordillera. Petrological, geochemical, geochronological, and structural relationships link the eclogites at St. Cyr to other eclogite localities in Yukon, indicating the high-pressure assemblages form a larger lithotectonic unit within the Yukon-Tanana terrane.

Streszczenie:
The National Energy Board (NEB or the Board) is an independent regulatory tribunal that regulates various aspects of the Canadian energy industry, including the design, construction, operation and abandonment of oil and gas pipelines that cross provincial or international borders. Under section 74(1)(d) of the National Energy Board Act, a company shall not, without the leave of the Board, abandon the operation of a pipeline. To date, only one large-scale abandonment of an NEB-regulated pipeline has occurred. However, as pipeline infrastructure ages and markets shift, pipeline abandonments are likely to become more common. It is therefore important to review and learn from this case so that industry and regulators may effect future abandonments in as efficient and environmentally responsible a manner as possible. The Yukon Pipeline was part of the Canol Pipeline built by the United States Army in 1942. From 1958 through 1994, Yukon Pipelines Limited (YPL) and related companies operated the portion of pipeline from Skagway, Alaska, to Whitehorse, Yukon, to transport furnace oil, diesel fuel and gasoline to Whitehorse for distribution and use in the Yukon. The 114 km Canadian portion of the Yukon Pipeline, as well as an associated pump station at Carcross, Yukon, and a tank farm in Whitehorse, have been regulated by the NEB since 1962. An abandonment hearing was held in 1996, and the NEB issued a conditional order granting YPL leave to abandon the pipeline. The order would not come into force until YPL conducted further contaminant investigation and planned and successfully completed remedial work, all in consultation with a variety of stakeholders and regulatory bodies. The physical abandonment of the YPL facilities was relatively straightforward. Significant issues pertain primarily to the ongoing associated remediation of historical contamination. Challenges include appropriate characterization of the site, changing environmental standards and regulatory frameworks, changes in approach to remediation of the site, and complex jurisdictional interactions. Special concerns pertain to the application of environmental risk assessment and risk management. In order for future abandonment projects to proceed efficiently and effectively, it is recommended that site characterization and risk assessment work be completed early in the process, that risk management planning also be completed as early as possible (including planning how site closure will be achieved within the applicable regulatory context), and that the abandonment process and provisions be sufficiently flexible to accommodate changing circumstances while still achieving the desired end result.

Streszczenie:
West-central Yukon and eastern Alaska are characterized by widespread metamorphic rocks that form part of the allochthonous, composite Yukon-Tanana terrane and parautochthonous North American margin. Structural windows through the Yukon-Tanana terrane expose parautochthonous North American margin in that broad region, particularly as mid-Cretaceous extensional core complexes. Both the Yukon-Tanana terrane and parautochthonous North American margin share the same Late Devonian history, making their discrimination difficult; however, distinct post-Late Devonian magmatic and metamorphic histories assist in discriminating Yukon-Tanana terrane from parautochthonous North American margin rocks. The suture between Yukon-Tanana terrane and parautochthonous North American margin is obscured by many episodes of high-strain deformation. Their main bounding structure is probably a Jurassic to Cretaceous thrust, which has been locally reactivated as a mid-Cretaceous extensional shear zone. Crustal-scale structures within composite Yukon-Tanana terrane (e.g. the Yukon River shear zone) are commonly marked by discontinuous mafic-ultramafic complexes. Some of these complexes represent orogenic peridotites that were structurally exhumed into the Yukon-Tanana terrane in the Middle Permian.
