Synchrotron source FTIR data (high-pressure, high-temperature) on chrysene, C18H12.
<p>This dataset contains experimental data collected on chrysene, C18H12, in a diamond anvil cell at pressures up to 10 GPa and a temperature range of 30-300 C</p> <p>Experimental data: synchrotron source FTIR data collected at Beamline X01DC in 2009, using the instrumentation documented in "<a href="http://dx.doi.org/10.1021/jp105020f">Stability of Coronene at High Temperature and Pressure</a>," <em>JOURNAL OF PHYSICAL CHEMISTRY B</em>, Vol: 114, Pages: 15753-15758, ISSN: 1520-6106, doi: 10.1021/jp105020f. FTIR-microspectrometry in transmission was performed using synchrotron light at the Swiss Light Source operated in top-up mode. Thus the infrared intensity remains constant with time. The IR focus available at the end of the beamline was coupled to the side port of a Bruker Vertex 70 FTIR spectrometer with an <em>f</em>1 = 34 mm/<em>f</em>2 = 213 mm ellipsoidal mirror. The spectrometer, equipped with a KBr beamsplitter, was coupled to the input of a Bruker Hyperion IR microscope without any additional optics. The microscope was equipped with two ×15 gold-coated Cassegrain objectives. The illuminated region of the sample was determined by an aperture of some 20−45 μm × 20−45 μm. In order to reduce the effect of scattered light and to enhance contrast fidelity, an identical conjugate aperture was placed between the collecting optics and the nitrogen-cooled mercury−cadmium−telluride (MCT) detector. Resolution and number of coadded scans were 4 cm<sup>−1</sup> and 256, respectively. Crystals were observed in parallel by use of white light and a charge-coupled device (CCD) camera.</p> <p>Each zip file contains data files in raw (OPUS) and plain text (.dpt) formats, and a pdf scane of the labbook, which provides a key to relate the file names to the pressure/temeprature of the sample. Raw files are provided for both the background and the sample; plain text files were created from processed files. </p>

Data from: A modelling framework to assess the effect of pressures on river abiotic habitat conditions and biota
River biota are affected by global reach-scale pressures, but most approaches for predicting biota of rivers focus on river reach or segment scale processes and habitats. Moreover, these approaches do not consider long-term morphological changes that affect habitat conditions. In this study, a modelling framework was further developed and tested to assess the effect of pressures at different spatial scales on reach-scale habitat conditions and biota. Ecohydrological and 1D hydrodynamic models were used to predict discharge and water quality at the catchment scale and the resulting water level at the downstream end of a study reach. Long-term reach morphology was modelled using empirical regime equations, meander migration and 2D morphodynamic models. The respective flow and substrate conditions in the study reach were predicted using a 2D hydrodynamic model, and the suitability of these habitats was assessed with novel habitat models. In addition, dispersal models for fish and macroinvertebrates were developed to assess the re-colonization potential and to finally compare habitat suitability and the availability / ability of species to colonize these habitats. Applicability was tested and model performance was assessed by comparing observed and predicted conditions in the lowland Treene River in northern Germany. Technically, it was possible to link the different models, but future applications would benefit from the development of open source software for all modelling steps to enable fully automated model runs. Future research needs concern the physical modelling of long-term morphodynamics, feedback of biota (e.g., macrophytes) on abiotic habitat conditions, species interactions, and empirical data on the hydraulic habitat suitability and dispersal abilities of macroinvertebrates. The modelling framework is flexible and allows for including additional models and investigating different research and management questions, e.g., in climate impact research as well as river restoration and management.
Data from: Sixty years of anthropogenic pressure: a spatio-temporal genetic analysis of brown trout populations subject to stocking and population declines
Analyses of historical samples can provide invaluable information on changes to the genetic composition of natural populations resulting from human activities. Here, we analyze 21 microsatellite loci in historical (archived scales from 1927-1956) and contemporary samples of brown trout (Salmo trutta) from six neighbouring rivers in Denmark, to compare the genetic structure of wild populations before and after population declines and stocking with non-local strains of hatchery trout. We show that all populations have been strongly affected by stocking, with admixture proportions ranging from 14 to 64%. Historical population genetic structure was characterized by isolation-by-distance and by positive correlations between historical effective population sizes and habitat area within river systems. Contemporary population genetic structure still showed isolation-by-distance, but also reflected differences among populations in hatchery trout admixture proportions. Despite significant changes to the genetic composition within populations over time, dispersal rates among populations were roughly similar before and after stocking. We also assessed whether population declines or introgression by hatchery strain trout should be the most significant conservation concern in this system. Based on theoretical considerations, we argue that population declines have had limited negative effects for the persistence of adaptive variation, but admixture with hatchery trout may have resulted in reduced local adaptation. Collectively, our study demonstrates the usefulness of analyzing historical samples for identifying the most important consequences of human activities on the genetic structure of wild populations.
Data from: Understanding the biological invasion risk posed by the global wildlife trade: propagule pressure drives the introduction and establishment of Nearctic turtles
Biological invasions are a key component of human-induced global change. The continuing increase in global wildlife trade has raised concerns about the parallel increase in the number of new invasive species. However, the factors that link the wildlife trade to the biological invasion process are still poorly understood. Moreover, there are analytical challenges in researching the role of global wildlife trade in biological invasions, particularly issues related to the under-reporting of introduced and established populations in areas with reduced sampling effort. In this work, we use high-quality data on the international trade in Nearctic turtles (1999–2009) coupled with a statistical modelling framework, which explicitly accounts for detection, to investigate the factors that influence the introduction (release, or escape into the wild) of globally traded Nearctic turtles and the establishment success (self-sustaining exotic populations) of slider turtles (Trachemys scripta), the most frequently traded turtle species. We found that the introduction of a species was influenced by the total number of turtles exported to a jurisdiction and the age at maturity of the species, while the establishment success of slider turtles was best associated with the propagule number (number of release events), and the number of native turtles in the jurisdiction of introduction. These results indicate both a direct and indirect association between the wildlife trade and the introduction of turtles and establishment success of slider turtles, respectively. Our results highlight the existence of gaps in the number of globally recorded introduction events and established populations of slider turtles, although the expected bias is low. We emphasize the importance of researching independently the factors that affect the different stages of the invasion pathway. Critically, we observe that the number of traded individuals might not always be an adequate proxy for propagule pressure and establishment success.
Data from: Adaptations and responses of the common dandelion to low atmospheric pressure in high altitude environments
<p>Atmospheric pressure is an important, yet understudied factor that may shape plant ecology and evolution.</p> <p>By growing plants under controlled conditions at different experimental stations in the Swiss alps, we evaluated the impact of ecologically realistic atmospheric pressures between 660 and 950 hPa on the growth and defence of different dandelion populations.</p> <p>Low atmospheric pressure was associated with reduced root growth and defensive sesquiterpene lactone production. Defence suppression only occurred in populations originating from lower altitudes. Populations from higher altitudes constitutively produced less sesquiterpene lactones and did not suffer from suppression under low atmospheric pressure.</p> <p><em>Synthesis</em>. We conclude that atmospheric pressure modulates root growth and defence traits, and that evolutionary history shapes plant phenotypic responses to atmospheric pressure. Our findings have important implications for our understanding of altitudinal gradients and the future use of plants as a source of food and bioactive metabolites in extraterrestrial habitats.</p>

Data from: Larval dispersal and fishing pressure influence recruitment in a coral reef fishery
<ol> <li><span>Understanding larval connectivity patterns in exploited fishes is a fundamental prerequisite for developing effective management strategies and assessing the vulnerability of a fishery to recruitment overfishing and localised extinction. To date however, researchers have not considered how regional variations in fishing pressure also influence recruitment. </span></li> <li><span>We used genetic parentage analyses and modelling to infer the dispersal patterns of bumphead parrotfish (<i>Bolbometopon muricatum</i>) larvae in the Kia fishing grounds, Isabel Province, Solomon Islands. We then extrapolated our Kia dispersal model to a regional scale by mapping the available nursery and adult habitat for <i>B. muricatum</i> in six regions in the western Solomon Islands, and estimated the relative abundance of adult <i>B. muricatum</i> populations in each of these regions based on available adult habitat and historical and current fishing pressure. </span></li> <li><span><span>Parentage analysis identified 67 juveniles that were the offspring of parents sampled in the Kia fishing grounds. A </span>fitted larval dispersal kernel<span> predicted that 50% of larvae settled within 30 km of their parents, and 95% settled within 85 km of their parents. After accounting for unsampled adults, our model predicted that 34% of recruitment to the Kia fishery was spawned locally. Extrapolating the spatial resolution of the model revealed that a high proportion of the larvae recruiting into the Kia fishing grounds came from nearby regions that had abundant adult populations. </span>Other islands in the archipelago provided few recruits to the Kia fishing grounds, reflecting the greater distances to these islands and lower adult abundances in some regions. </span></li> <li> <em>Synthesis and <a>applications</a></em><em>: </em>This study shows how recruitment into a commercial reef fishery is influenced by larval dispersal patterns and regional variations in historical fishing pressure. The scales of larval connectivity observed for <i>B. muricatum</i> indicate that recruitment overfishing is unlikely if there are lightly exploited reefs up to 85 km away from a heavily fished region, and that small marine protected areas (MPAs) are insufficient to protect this species. We recommend greater efforts to understand the interactions between larval dispersal and gradients of fishing pressure, as this will enable the development of tailored fisheries management <a>strategies.</a> </li> </ol>

Shear experiment datas for laumontite and mixed gouges at different temperatures and pore pressures
<p><span>Laumontite is a common and potentially frictionally-unstable hydrothermal alteration product present in deep faults of the Gonghe EGS reservoir. We characterize the friction-stability characteristics of synthetic laumontite gouge under <em>in situ</em> reservoir conditions. The gouge is frictionally strong (μ=0.73</span><span>–</span><span>0.98) with quartz/laumontite mixtures (1:1) generally less strong (μ=</span><span>0.73</span><span>–</span><span>0.78</span><span>) with both largely independent of temperature but increasing with elevated pore pressure. The pure gouge and mixture are strongly velocity-weakening over a broad range in temperatures (~90</span><span>–</span><span>220℃) and excess pore pressures (0</span><span>–</span><span>90MPa) relevant to the Gonghe stimulation. Microearthquakes (MEQs) observed during stimulation are confined to within the broad depth range of inferred frictional instability – although fluid overpressures are also limited to this region. The observation that laumontite mixtures are frictionally unstable over a broad range of pressures and especially temperatures representative of EGS reservoirs and insensitive to the proportion of the coexisting mineral phase suggests its presence is a strong indicator of potential seismic hazard – and thus worthy of careful consideration. </span></p>
