Genomic and phenotypic architecture of a spruce hybrid zone (Picea sitchensis x P. glauca)
Creators: name: Hamilton, Jill Adelle

Year: 2012

description: Natural hybrid zones may be viewed as important biological systems for examining the role of selection in creating and maintaining species differences. Where ecological differences exist between hybridizing species, these zones may provide useful insight into the genetic architecture of important traits involved in adaptation. I have evaluated the genomic and phenotypic architecture of the economically and ecologically important Picea sitchensis (Sitka spruce) x P. glauca (white spruce) hybrid zone along the Nass and Skeena river valleys in northwestern British Columbia using chloroplast and mitochondrial markers, twelve microsatellite loci (SSRs), and 268 single nucleotide polymorphisms (SNPs), in combination with morphological variation, and phenotypic data from a common garden. Maternally- and paternally-inherited organelle markers, in combination with bi-parentally inherited nuclear markers, were used to estimate both the historic and contemporary direction and extent of gene flow within the hybrid zone. Sitka spruce mitotype ‘capture’ throughout the introgression zone point towards asymmetric gene flow, congruent with microsatellites and SNPs, indicating extensive long-term introgression and widespread recombination with more Sitka spruce than white spruce ancestry in hybrid populations. Significant clinal variation was observed for marker-based hybrid indices and morphological traits associated with climate and geography, while growth and cold hardiness traits evaluated in a common garden exhibited weak to non-significant clines. These results indicate extrinsic selection appears to play a strong role in the distribution and structure of this hybrid zone, which fits expectations for the environmentally-determined bounded hybrid superiority model of hybrid zone maintenance. However, intrinsic mechanisms of hybrid zone maintenance could not be ruled out. Finally, broad-scale patterns of variation, combined with fine-scale analysis of candidate SNP-specific patterns of introgression revealed a suite of candidate loci that may be targets of extrinsic or intrinsic selection. These loci may be involved in either adaptation to climate across the zone, particularly precipitation gradients, or involved in the maintenance of species barriers. These results have important implications for genetic conservation of adaptive variation, selection of seed sources for current reforestation within this ecologically transitional area, and appropriate scale and direction of seed transfer relating current genotype-climate associations to future climate predictions for this region.

description: We show that quantum resistance standards made of transferred graphene reach the uncertainty of semiconductor devices, the current reference system in metrology. A large graphene device (150 \times 30 \mum2), exfoliated and transferred onto GaAs, revealed a quantization with a precision of (-5.1 \pm 6.3) \times 10-9 accompanied by a vanishing longitudinal resistance at current levels exceeding 10 \muA. While such performance had previously only been achieved with epitaxially grown graphene, our experiments demonstrate that transfer steps, inevitable for exfoliated graphene or graphene grown by chemical vapor deposition (CVD), are compatible with the requirements of high quality quantum resistance standards.

Calomera lacrymosa

description: Calomera lacrymosa (Dejean, 1825) Material examined. 1 male, PHILIPPINES, Apayao Province, Municipality of Calanasan, Brgy. Tanglagan, [18.3737°N, 120.9610°E], IX.2018, coll. R.J. T. Villanueva (Fig. 2); UMCRC 01011. Identification. This species is very similar to Calomera mindanaoensis Cassola, 2000 in appearance and size, the absence of visible elytra punctuation, and in the labrum with more than 10 marginal setae. However, C. lacrymosa has elaborate markings on the side compared to C. mindanaoensis. Both species have their pronotum and elytra metallic green and red in color, but C. lacrymosa has a larger anterior lateral dot, and in that species the discal dot is somewhat connected with a narrow lineole. Moreover, the aedeagus of C. mindanaoensis is arcshape and slightly tapering at the apex, but the aedeagus of C. lacrymosa is also arc-shaped but much longer and thinner towards the apex. Endemism and distribution. An Oriental species; Philippines (Luzon, Palawan, Sibuyan, Balabac, Mindoro, Homonhon, Bucas Grande) and Indonesia (Sulawesi), although this range is still under investigation (Cabras et al. 2016b). Remarks. This species was observed at only one of the nine sites explored. It was found perching on the ground on a sun-exposed road in an agricultural area. It was rather rare in the area. Cassola (2000) gave an excellent historical account of this species and a brief description under the name Lophyridia lacrymosa (Dejean, 1825). Later, Cassola (2011) considered Lophyridia Jeannel, 1946, as junior synonym of Calomera Motschulsky, 1862, and hence, L. lacrymosa is now C. lacrymosa. This species is widespread in the Philippines, from Luzon south to Mindanao. Cabras et al. (2016) listed several major islands in the distributional range of the species, with a questionable account from Sulawesi.

description: No abstracts are to be cited without prior reference to the author.The movement of ballast water by transoceanic ships has been recognized globally as a primary vector for the introduction of non-indigenous species (NIS). Most research efforts have accordingly been aimed at the management of transoceanic ballast; however, it represents only one aspect of the broader issue of NIS management in the Great Lakes. Great Lakes’ ports may receive ballast from domestic and transoceanic vessels, and both ballast types could potentially serve as vectors for NIS introduction. Currently, domestic ballast operations associated with “laker” vessels in the Great Lakes-St Lawrence River are regarded as low risk, therefore, little research has been done to determine whether these vessels to the Great Lakes contribute to the introduction and spread of NIS. There are 11 freshwater and 5 estuarine ports on the St Lawrence River used by lakers for ballast operations; some of these ports are also visited by transoceanic vessels, opening the possibility that: (i) species native to the St Lawrence River but not present in the Great Lakes could be introduced to the lakes; (ii) NIS species are delivered to the Great Lakes in secondary transfers. Here we examine the invasion risk St Lawrence River ports pose to the Great Lakes by examining (i) invertebrate community similarity between St Lawrence River and Great Lakes’ ports; (ii) the diversity and abundance of NIS in the ballast water of lakers, and (iii) the environmental match between St Lawrence River and Great Lakes’ ports.

Tanglagan [18.3674°N, 120.9571°E], IX.2018, coll. R.J. T. Villanueva (Fig. 3B); UMCRC 010132, UMCRC 010133. Identification. This species is very similar to C. werneri Wiesner, 1988 and C. vanderberghei Dheurle, 2016, in having the head shiny, bluish-violet above and metallic green to bluish-green on the clypeus, frons, antennal plates, and genae (Cassola and Werner 2003). However, brown pigmentation is present at the tip of each elytron in C. genieri but absent in both C. werneri and C. vanderberghei. The aedeagus of C. genieri and C. werneri have the inner sac with a long, narrow flagellum whose upper convolution is crossed by a V-shaped sclerite (Cassola and Werner 2003), but the aedeagus of C. genieri is fusiform, with a straight, blunt apex compared to the slightly tapering apex of C. werneri. Remarks. This species was found on a steep slope along a forest trail. It was perching atop a fallen dried leaf on the ground. Unlike other species of tiger beetle encountered during this study, which climb into the insect net, when a net is positioned above an individual of this species, it tends to drop to the ground and crawl under a leaf or sometimes into a small crevice in the ground.

description: The Visual Physics Analysis (VISPA) project integrates different aspects of physics analyses into a graphical development environment. It addresses the typical development cycle of (re-)designing, executing and verifying an analysis. The project provides an extendable plug-in mechanism and includes plug-ins for designing the analysis flow, for running the analysis on batch systems, and for browsing the data content. The corresponding plug-ins are based on an object-oriented toolkit for modular data analysis. We introduce the main concepts of the project, describe the technical realization and demonstrate the functionality in example applications.

description: No abstracts are to be cited without prior reference to the author.Non-indigenous fauna are now recognized as one of the most serious threats to the natural ecology of biological systems worldwide. To analyse its abundance in the internal and external areas of the “Abra of Bilbao” we carried out a survey during summer 2009 of nine intertidal and eight subtidal localities. This comprised a visual estimate of the faunal species abundance in 50×50 quadrats. We considered as native species those which are known to be endemic to the Basque biogeographical region. Non-indigenous species are those introduced as a result of human activities. Cryptogenic species are those whose identity as either native or non-indigenous remains ambiguous, whereas indeterminates include specimens that could not be reliably identified to species level. In the intertidal zone, 62 taxa were identified. In terms of abundance, cryptogenic species represent 54.1% of the total cover, natives 40.3%, non-indigenous species 5.3%, and indeterminates 0 3%. In relation to species richness, cryptogenic and non-indigenous species only represent 4.8% of the total diversity each, whereas native species represent 74.6% and indeterminates 14.3%. In the subtidal zone, 63 taxa were identified. In reference to the abundance, native species represent 78.4% of the total cover, cryptogenic species 14.7%, non-indigenous species 6.3%, and indeterminates 0.6%. As for the faunal diversity, native species represent 73.1% of the total richness, non-indigenous species 11.1%, and cryptogenic and indeterminate species 7.9% each.

description: Let X be a smooth manifold of dimension 1+n endowed with a lorentzian metric g, and let T be the electromagnetic energy tensor associated to a 2-form F. In this paper we characterize this tensor T as the only 2-covariant natural tensor associated to a lorentzian metric and a 2-form that is independent of the unit of scale and satisfies certain condition on its divergence. This characterization is motivated on physical grounds, and can be used to justify the Einstein-Maxwell field equations. More generally, we characterize in a similar manner the energy tensor associated to a differential form of arbitrary order k. Finally, we develop a generalized theory of electromagnetism where charged particles are not punctual, but of an arbitrary fixed dimension p. In this theory, the electromagnetic field F is a differential form of order 2+p and its electromagnetic energy tensor is precisely the energy tensor associated to F.

description: The anisotropy of the azimuthal distributions of charged particles produced in PbPb collisions with a nucleon-nucleon center-of-mass energy of 2.76 TeV is studied with the CMS experiment at the LHC. The elliptic anisotropy parameter defined as the second coefficient in a Fourier expansion of the particle invariant yields, is extracted using the event-plane method, two- and four-particle cumulants, and Lee--Yang zeros. The anisotropy is presented as a function of transverse momentum (pt), pseudorapidity (eta) over a broad kinematic range: 0.3 < pt < 20 GeV, abs(eta) < 2.4, and in 12 classes of collision centrality from 0 to 80%. The results are compared to those obtained at lower center-of-mass energies, and various scaling behaviors are examined. When scaled by the geometric eccentricity of the collision zone, the elliptic anisotropy is found to obey a universal scaling with the transverse particle density for different collision systems and center-of-mass energies.

Assessing the utility of ground penetrating radar in archaeology on the Northwest Coast : the 'new wave', 'all Snell', or 'it just hertz'?
Creators: name: Dojack, Lisa Marie
Publisher: name: University of British Columbia

description: This project investigates the application of ground penetrating radar (GPR), a remote sensing geophysical survey method, to the archaeological investigation of earthen architecture on the Northwest Coast of North America. The objective of this thesis is to assess the ability of GPR to detect and distinguish between architectural features within an earthen matrix, and to understand the limitations and uncertainties of the method in this and similar contexts. This thesis also assesses the ability of GPR to provide data that are able to contribute to broad anthropological questions of demographic change and socio-political complexity. GPR was used at Welqámex (DiRi-15), a Stó:lō-Coast Salish settlement near Hope, British Columbia, to collect nearly 1,000 m2 of data over a minimum of 11 structures. GPR data were analysed with comparison to surface and subsurface data from Welqámex, including excavation data collected prior to and following GPR survey. The survey identified 157 anomalies that may be useful in guiding future excavations. Direct comparisons of GPR reflection profiles and amplitude slices with excavation stratigraphic profiles and plan views indicate that GPR is moderately successful in detecting sqémél floors, s’iltexwáwtxw floors, and pit features larger than 15 cm in diameter, but is not successful in detecting post and stake mold features larger than 15 cm in diameter, hearth features, and structure boundaries. The anomalies produced from these features, however, are not easily distinguished from one another or from other natural and archaeological features. The results suggest that while GPR is able to identify anomalies that may be useful in guiding archaeological excavation, it is at this time not an ideal method for addressing broader anthropological questions on its own.

description: We study glueballs in the holographic gauge theories, supersymmetric and non-super symmetric cases, which are given by the type IIB superstring solutions with non-trivial dilaton. In both cases, the dilaton reflects the condensate of the gauge field strength, $$, which is responsible to the linear confining potential between the quark and anti-quark. Then we could see the meson spectra. On the other hand, the glueball spectra are not found in the supersymmetric case. We need a sharp wall, which corresponds to an infrared cutoff, in order to obtain the glueballs. In the non-supersymmetric case, the quantized glueballs are actually observed due to the existence of such a wall driven by the dilaton. The strings and D-branes introduced as building blocks of hadrons are pushed out by this wall, and we could see the Regge behavior of the higher spin meson and glueball states. We find that the slope of the glueball trajectory is half of the flavor meson's one. As for the low spin glueballs, they are studied by solving the fluctuations of the bulk fields, and their discrete spectra are shown.

description: No abstracts are to be cited without prior reference to the author.Although spatially explicit individual-based models (IBMs) of larval fish provide invaluable information on connectivity and distribution of early life-history stages, results are difficult to incorporate into management decisions. One way in which IBM outputs have been used is in full life-history simulations used to investigate spatial population structure or the effects of various management strategies. Little work has been done, however, to incorporate IBM results directly into a stock assessment framework. We describe a method for incorporating IBM estimates of larval mixing rates directly within the objective function of a forward projecting, multiregion statistical catch-at-age model. This model allows for full life cycle closure by following fish from birth (age-0) instead of from age-1, and allowing for larval drift and adult movement between subpopulations. Larval IBM results are used as a ”data” source in the model and each IBM particle is treated as if it were a ”tagged” fish in a mark–recapture dataset. The objective function for the assessment model includes multiple data sources including catch-at-age, abundance indices, mark–recapture tagging data, and larval IBM data. This is one of the first quantitative, full life-history metapopulation models presented within a stock assessment framework. In addition, it provides a new way for IBM data to be directly incorporated into management decisions, because such decisions are often based on stock assessment outputs.

description: No abstracts are to be cited without prior reference to the author.When computer models are coupled together it is necessary to describe both the physical connections between the models (file formats, network protocols, and the like) and semantic information about what the data mean (grid type and dimensions, names of organisms and variables and the units in which numerical quantities are expressed). In some cases, there are incompatibilities but mechanisms exist to convert between different representations, for example converting units of wet mass per unit volume into molar units of chlorophyll or carbon. Couplerlib is a library for doing this where the semantic information is stored as a dictionary of xml definitions for unit conversions and names and hierarchies of functional groups. We have linked two models; one is the biogeochemical model BFM, embedded in the physical model GOTM (General Ocean Turbulence Model), and the other is the Ecosim ecological model. The xml dictionary expresses the semantic relations between the entities in the two models and a second xml file specifies which groups are linked (in this case phytoplankton and zooplankton). When the two models are linked and exchange information on a daily basis, the plankton dynamics predicted by the GOTM-BFM model feed through to the dynamics of the groups in Ecosim that feed on them and the predation effects can be seen in GOTM-BFM. Currently, this model linking approach is being extended to three-dimensional models running across networks of computers.

Heptodonta analis is easily distinguished from H. melanopyga by its greenish body and paler ventral side. In addition, H. melanopyga has metallic coppery brown elytron. The black pronotum of H.melanopyga is tinge with green on the sides, while H. analis is entirely metallic green. In both species, the aedeagus is almost the same size, with a slightly curved, tapering apex. Endemism and distribution. A Philippine endemic; Sibuyan, Nueva Viscaya, Ilocos Norte (Adams), Batan, Mindanao (Cabras et al. 2016b, 2016c; Cassola 2000). Remarks. This species is very abundant, found forming a colony on well-exposed sandy ground near the irrigation dam in Sitio Maranas. Interestingly, this species was seen in the upper and lower stretch of the rivers of Barangay Tanglagan and Barangay.

description: We show that in experimental atomic force microscopy studies of the lifetime distribution of mechanically stressed folded proteins the effects of externally applied fluctuations can not be distinguished from those of internally present fluctuations. In certain circumstances this leads to artificially non-exponential lifetime distributions which can be misinterpreted as a signature of protein complexity. This work highlights the importance of fully characterizing and controlling external sources of fluctuation in mechanical studies of proteins before drawing conclusions on the physics at play on the molecular level.
Detection of a divot in the size distribution of the Kuiper Belt's scattering objects
Creators: name: Shankman, Cory Jason
Publisher: name: University of British Columbia
Year: 2012

description: We present a joint analysis of the Canada France Ecliptic Plane Survey's scattering objects, and the Kaib et al. (2011b) orbital model, measuring the scattering objects' size distribution. Scattering objects are Trans-Neptunian objects which are strongly interacting with Neptune, having scattering encounters which change their semimajor axes on short dynamical timescales. We reject a single power-law distribution at the 99% level, and find that a dearth of small objects is required. We present a novel parameterisation of a divot size distribution, which rises as a single power-law to a precipitous drop, then recovers as another single power-law of potentially different slope. We constrain the form of such a divot distribution, and find that divots are preferred over "knee" size distributions, which are found elsewhere in the literature for different populations. We present our preferred divot scenario, which rises as a single power-law of logarithmic slope α = 0.8 as absolute Hg magnitudes increase to sizes corresponding to D ~ 100 km, then dropping by a factor of about 6 in differential number, followed by another single power-law of logarithmic slope α = 0.5. Our interpretation is that this feature arose from the size distribution made by planetesimal formation and is now "frozen in" to the "hot" populations of the outer Solar System. From this we estimate there are 2‧10⁹ scattering objects with Hg < 18, allowing for enough to supply the nearby Jupiter Family comets. This interpretation nicely ties the "hot" populations together while simultaneously explaining the source of the Jupiter Family comets and the observed paucity of intermediate-sized (50-100 km) Neptune Trojans.

description: We study a strongly interacting "quantum dot 1" and a weakly interacting "dot 2" connected in parallel to metallic leads. Gate voltages can drive the system between Kondo-quenched and non-Kondo free-moment phases separated by Kosterlitz-Thouless quantum phase transitions. Away from the immediate vicinity of the quantum phase transitions, the physical properties retain signatures of first-order transitions found previously to arise when dot 2 is strictly noninteracting. As interactions in dot 2 become stronger relative to the dot-lead coupling, the free moment in the non-Kondo phase evolves smoothly from an isolated spin-one-half in dot 1 to a many-body doublet arising from the incomplete Kondo compensation by the leads of a combined dot spin-one. These limits, which feature very different spin correlations between dot and lead electrons, can be distinguished by weak-bias conductance measurements performed at finite temperatures.

Parina [18.4291°N, 120.9713°E] IX–X.2018, coll. R.J. T. Villanueva (Fig. 5B); UMCRC 010149, UMCRC 010150, UMCRC 010151, UMCRC 010152. Identification. Therates monticola is easily distinguished by the color pattern of its elytra and its smaller size compared to the most similar species of Therates, namely T. fasciatus fasciatus (Fabricius, 1801), T. pseudosemperi W. Horn, 1928, and T. negrosicola Zettel & Pangantihon, 2017. Therates monticola is very similar to T. semperi Schaum, 1860 in size but morphologically differs in having reduced punctation of the elytra, an entirely orange prothorax and mesoepisternum, an absent or small black circumscutellary mark, and large black medial marks on the elytra. Therates monticola has a black central mark of its elytron but it is short located near the apex (Zettel and Pangantihon 2017). The aedeagus is moderately slender, and its dorsal side is not emarginated. Remarks. This species was living with T. coracinus coracinus in open to partially shaded streams. Zettel and Pangantihon (2017) described this species recently, with the type locality in the Cordillera Central, Mountain Province Philippines.

description: The presence of a dark matter core in the central kiloparsec of many dwarf galaxies has been a long standing problem in galaxy formation theories based on the standard cold dark matter paradigm. Recent cosmological simulations, based on Smooth Particle Hydrodynamics and rather strong feedback recipes have shown that it was indeed possible to form extended dark matter cores using baryonic processes related to a more realistic treatment of the interstellar medium. Using adaptive mesh refinement, together with a new, stronger supernovae feedback scheme that we have recently implemented in the RAMSES code, we show that it is also possible to form a prominent dark matter core within the well-controlled framework of an isolated, initially cuspy, 10 billion solar masses dark matter halo. Although our numerical experiment is idealized, it allows a clean and unambiguous identification of the dark matter core formation process. Our dark matter inner profile is well fitted by a pseudo-isothermal profile with a core radius of 800 pc. The core formation mechanism is consistent with the one proposed recently by Pontzen & Governato. We highlight two key observational predictions of all simulations that find cusp-core transformations: (i) a bursty star formation history with peak to trough ratio of 5 to 10 and a duty cycle comparable to the local dynamical time; and (ii) a stellar distribution that is hot with v/sigma=1. We compare the observational properties of our model galaxy with recent measurements of the isolated dwarf WLM. We show that the spatial and kinematical distribution of stars and HI gas are in striking agreement with observations, supporting the fundamental role played by stellar feedback in shaping both the stellar and dark matter distribution.

description: The dynamics of metric perturbations is explored in the gravity theory with anomaly-induced quantum corrections. Our first purpose is to derive the equation for gravitational waves in this theory on the general homogeneous and isotropic background, and then verify the stability of such background with respect to metric perturbations. The problem under consideration has several interesting applications. Our first purpose is to explore the stability of the classical cosmological solutions in the theory with quantum effects taken into account. There is an interesting literature about stability of Minkowski and de Sitter spaces and here we extend the consideration also to the radiation and matter dominated cosmologies. Furthermore, we analyze the behavior of metric perturbations during inflationary period, in the stable phase of the Modified Starobinsky inflation.

description: No abstracts are to be cited without prior reference to the author.An NPZDF model with an explicit two-way interaction between an NPZD model and a fish model component is presented for the example of the Baltic Sea. In the Baltic, the fish stock is dominated by two prey species (sprat and herring) and one predator (cod). The dynamics of the fish model is driven by size (mass–class) dependent predator–prey interactions, while the interaction between the NPZD and fish model components is established through feeding of prey fish on zooplankton and recycling of fish biomass to nutrients and detritus. The model strictly conserves mass. The performance of the NPZDF model is illustrated by simulating fishing scenarios and effects of eutrophication for a box model. In principle, the model allows us to build a fish model component into a three-dimensional ecosystem model of the Baltic Sea or other systems. Some issues related to embedding the model into a three-dimensional model systems are discussed and problems of representing fish stock dynamics in a coarse resolution model are addressed.

description: We introduce the notion of a crystal base of a finite dimensional q-deformed Kac module over the quantum superalgebra $U_q(\gl(m|n))$, and prove its existence and uniqueness. In particular, we obtain the crystal base of a finite dimensional irreducible $U_q(\gl(m|n))$-module with typical highest weight. We also show that the crystal base of a q-deformed Kac module is compatible with that of its irreducible quotient $V(λ)$ given by Benkart, Kang and Kashiwara when $V(λ)$ is an irreducible polynomial representation.

description: No abstracts are to be cited without prior reference to the author.Climate change affects a range of abiotic factors in the oceans that are tightly linked to the production and distribution of fish populations. Such changes in environmental variables (e.g. temperature) may directly affect populations at the individual level by causing changes in physiological rates. Understanding such ecophysiological responses is crucial in gaining mechanistic understanding of observed changes in species distribution patterns or behaviour in relation to climate change. In this study, we hypothesize that increasing temperatures in the North Sea affect the habitat quality of plaice in terms of the potential scope for growth and thus may lead to changes in their spatial distribution. Dynamic energy budget (DEB) models are used to predict weekly length-dependent growth rates of juvenile and adult plaice on a ~10 × 10 km spatial grid of the North Sea. Past and future temperatures for each grid cell are obtained from the ECOSMO model and used to calculate scope for growth for both past climate conditions and future predictions. Seasonal as well as annual variability in food availability are taken into account and winter survival of 0-group plaice is investigated following different summer feeding conditions. Changes in the spatial distribution of habitat quality (potential scope for growth) are discussed in relation to observed offshore shifts of plaice in recent years.
Birkhoff's Theorem in Higher Derivative Theories of Gravity II: Asymptotically Lifshitz Black Holes

description: As a continuation of a previous work, here we examine the admittance of Birkhoff's theorem in a class of higher derivative theories of gravity. This class is contained in a larger class of theories which are characterized by the property that the trace of the field equations are of second order in the metric. The action representing these theories are given by a sum of higher curvature terms. Moreover the terms of a fixed order k in the curvature are constructed by taking a complete contraction of k conformal tensors. The general spherically (hyperbolic or plane) symmetric solution is then given by a static asymptotically Lifshitz black hole with the dynamical exponent equal to the spacetime dimensions. However, theories which are homogeneous in the curvature (i.e., of fixed order k) possess additional symmetry which manifests as an arbitrary conformal factor in the general solution. So, these theories are analyzed separately and have been further divided into two classes depending on the order and the spacetime dimensions.

description: The Barrow Area Information Database (BAID) comprises a suite of interactive tools and map interfaces used by researchers, field

logistics personnel and program managers to gain insights into the field research activities on the North Slope of Alaska. BAID provides a rich history of Arctic field research plots, identifies current research sites and instrument locations, and sets field research within the context of the surrounding indigenous communities and traditional land use. Data archives, such as the National Snow and Ice Data Center (NSIDC), ultimately distribute the data resulting from efforts at these research sites. However, no robust cyberinfrastructure link exists between the data collection domain of BAID and the data products housed at NSIDC and other archives. This poster will review work currently in progress to identify and implement the services and interfaces needed to nabuild a bridge between BAID and the NSIDC data holdings.

description: No abstracts are to be cited without prior reference to the author.Fish populations show complex life cycles with different life stages exploiting a variety of habitats. Larval dispersal and fish movements spatially connect the habitats of the different life stages. Each life stage has particular habitat requirements and the availability of these may change in space and time with climate change. The response to hydroclimate variability and change may conflict in the different life stages. Therefore, to predict the response of populations to climate change, one needs to integrate over the entire life cycle. Spatially explicit models of anchovy spawning and larval dispersion were used sequentially to evaluate the population potential responses. We used the outputs of a coupled physical–biogeochemical model to access to the environmental forcing fields. A bioenergetic model resolved individual fish growth and reproduction and determined over different geographic regions the spawning time, duration, and total fecundity. The model provided the initial conditions for running a larval individual-based model to determine the drift and the survival of the larvae. Climate change scenarios were constructed by deviating major forcing parameters of the physical–biogeochemical model (wind, air temperature, short wave radiation, river run-off) from the current situation (reference years). These results of the scenarios were contrasted with the hindcast-simulated series. In scenarios with higher temperature, the spawning season was earlier, which affected the larval drifts, a situation which could be detrimental. The challenges in modelling life cycle closure are discussed.
