title: A simple method to assess the impact of sealing, headspace mixing and pressure vent on airtightness of manual closed chambers

description: The data set contains data from a full-factorial laboratory experiment, were three different designs and two modifications of typical manual closed chamber setups were tested for sealing integrity. Tests were performed using a simple method, based on injections of single CO2 pulses. Chamber designs differed in V:A-ratio nand chamber-collar sealing (water, rubber-foam, rubber-tube). All chambers were tested with and without pressure vent and fan. Included are measured CO2-concentration data as well as calculated sealing integrity in terms of chamber leakage. Results indicate significant differences in sealing integrity due to chamber-collar sealing strategy. The effect of pressure vent and fan, however, is of minor importance.

title: High resolution characterization of male ornamentation and reevaluation of sex-linkage in guppies

description: Data and Code for the paper:<br>HIGH-RESOLUTION CHARACTERIZATION OF MALE ORNAMENTATION AND REEVALUATION OF SEX LINKAGE IN GUPPIES <br>Abstract: Colouration plays a key role in the ecology of many species, influencing how an organism interacts with its environment, other species and conspecifics. Guppies are sexually dimorphic, with males displaying sexually selected colouration resulting from female preference. Previous work has suggested that much of guppy colour pattern variation is Y-linked. However, it remains unclear how many individual colour patterns are Y-linked in natural populations as much of the previous work has focused on phenotypes either not found in the wild, or aggregate measures such as total colour area. Moreover, ornaments have traditionally been identified and delineated by hand, and computational methods now make it possible to extract pixels and identify ornaments more automatedly, reducing the potential for human bias. Here we developed a pipeline for automated ornament identification and high-resolution image analysis of male guppy colour patterns and applied it to a multigenerational pedigree. Our results show that loci controlling the presence or absence of individual male ornaments in our population are not predominantly Y-linked. However, we find that ornaments of similar colour are not independent of each other, and modifier loci that affect whole animal colouration appear to be at least partially Y-linked. Considering these results, Y-linkage of individual ornaments may not be important in driving colour changes in natural populations of guppies, or in expansions of the non-recombining Y region, while Y-linked modifier loci that affect aggregate traits may well play an important role.

title: WireWall project data generated during the flume experiments performed at HR Wallingford during July to September 2018.

description: The prototype WireWall measurement system was initially trialled in the controlled environment of HR Wallingford's flume facility during three 5-day periods: 9th July 2018, 20th August 2018, 17th September 2018. An additional 5-day experiment was also run to collect data to compare with BayonetGPE: 3rd September 2018. In all experiments a 1:7.5 scale model of the beach and sea wall structure at Crosby (north of Liverpool, UK) was built within the flume using a laser scan collected 11th December 2013 by the Sefton Council. The flume was 45 m long, 2 m deep and 1.2 m wide. It was equipped with a piston-type wave paddle controlled by HR Wallingford's Merlin software. Wave and water level data to simulate conditions were obtained from the Liverpool Bay WaveNet buoy and Liverpool Gladstone Dock NTSLF tide gauge. During these experiments total cumulative wave-by-wave overtopping data were measured using collection tanks and WireWall. The collection tank data were recorded using small capacitance wire probes within the tanks. For long runs (over 100 waves) numerical estimates using the BayonetGPE tool (EurOtop 2018) was also used to assess its capability at this site. The data archived represented the total volume of water that overtopped the structure during each experiment, which comprised of different wave conditions and still water levels.

title: Sap flux density in 10 stems of a mature beech forest in the northeastern lowlands of Germany

description: Sap flux density was measured in 10 stems of a mature beech forest (Fagus sylvatica L.) in the northeastern lowlands of Germany during vegetation periods of years 2002 to 2005. The site represents an intensive monitoring core plot (DE1207) of the ICP Forests level II program (http://icp-forests.net/). The stand was growing on groundwater-distant, weakly degraded soil (Dystric Arenosol; FAO classification 1974). The humus type is moder. It was established in 1888 as a plantation under Scots pine (Pinus sylvestris L.) trees. Investigated trunks are described by stem diameter at breast height and tree height. Sap flow density of several depths of the trunks and data of the air temperature, air humidiy, global radiation, wind speed, and precipitation are given as hourly values. Xylem sap flux measurements performed to trees and tree stands allow differentiation of transpiration by different vegetation layers. The total transpiration of the canopy corresponds to the water flow through the trunk. Scaling from the sap flow measurement to stand transpiration is a two-step-procedure: firstly from sensor to tree and secondly from tree to stand. For the first step a radial profile of sap flow density is used. For scaling from tree to stand the structural inhomogeneity of the stand must be considered. The importance of this point is in even aged stands constricted, however, measurements should incorporate the differences of basal area and crown projected area of the trees.

title: Data sets of experimental study on retardation of a heavy NAPL vapor in partially saturated porous media

description: Large-scale column experiments were performed to quantify partitioning processes responsible for the retardation of carbon disulfide (CS2) vapor in partially saturated porous media. For experiments 1-16, fine glass beads (soda-lime glass, Sigmund Lindner, Warmensteinach, Germany) were used as medium; for experiments 17-37, Geba fine sand (Quarzsande GmbH, Eferding, Austria) was used. The experiments were conducted in large, vertical columns (i.d. = 0.109 m) of 2 m length packed with different porous media. A slug of CS2 vapor and the conservative tracer argon was injected at the bottom of the column followed by a nitrogen chase. Concentrations of CS2 and argon were measured at the top outlet of the column using two gas chromatographs (GC). The temporal-moment analysis (TMA) for step input was employed to evaluate concentration breakthrough curves and to calculate seepage velocity (v), dispersion (D) and retardation (R). The data sets contain for each experiment the raw data of the GC measurements of both CS2 and argon, temperature, pressure, and tensiometer recordings as well as the results of the TMA.

title: Mosquito monitoring data from active (2011-2017) and passive (2012-2017) surveillance

description: Mosquito monitoring data from active surveillance with BG-Sentinel traps from 2011 to 2017 and from passive surveillance - submissions to the "Mückenatlas" - between the years 2012 to 2017. The two different data sets are in one table, but separable by the table column "method". Locations of traps and submissions are not available due to data privacy regulations. The columns "bio.o" and "biocat" are only available for the passive surveillance entries as they depend on the participants notations about find spot that are not given in case of active surveillance by professional scientists.

title: A daily time-step observed and scenario climate dataset on a European grid for crop modelling applications Version 2

description: The data set contains daily time-step observed and scenario climate data on a European grid with 25 km x 25 km spatial resolution and is intended to be used for crop modelling applications. The dataset covers the period 1980-2010 for observations (for a baseline period of 1981-2010 and the year 1980 for crop model simulations with sowing dates in the autumn) and the periods 2040-2069 and 2070-2099 for 5 GCMs x 2 forcing scenarios (RCP4.5 and RCP8.5) and 2 GCMs with RCP2.6. The Joint Research Centre’s (JRC) Agri4Cast gridded dataset was used for the baseline. The scenarios have been calculated using an enhanced delta change method that applies changes in aspects of temperature and precipitation variability in addition to changes in mean climate.
description: The structure of the single tables refers to the gridcode of the model, for example the gridcode 35120 fits the location 35_120. This means the gridcode column is 120, the row 35. The explanation can be found in the properties of the kml file or the associated grid file. The data was generated by applying a “delta change factor” based on GCM outputs for RCP scenarios corresponding to the periods: 2040 until 2069 and from 2070 until 2099. As the “delta change factor” for these periods was applied to baseline observations for the period of 1.1.1980 to 31.12.2010, the dates for the respective scenario periods are still 1.1.1980 to 31.12.2010, due to the fact they are scenarios (ie, what would climate be relative to baseline climate). Pragmatically this avoids issues with different alignment of leap years between baseline and scenario periods. This is standard practice in climate data. Users of the data can adjust the dates as needed for their application.
description: Two versions of the dataset are available: version 1 (https://www.doi.org/10.4228/ZALF.DK.59; consisting of 8709 grid cells) that was used by Webber et al. (2018) and an updated version 2 (https://www.doi.org/10.4228/ZALF.DK.94; consisting of 8748 grid cells) that corrects an error when accounting for altitude differences to agricultural cultivation areas. It is recommended to use the latest version, unless the data are intended to be used for direct comparison with the results of Webber et al. (2018).

title: Strawberry fields forever: that is, how many grams of plastics are used to grow a strawberry?

description: In the agricultural sector, plastic is one of the most important tools for improving the managerial and economic performance of companies. The horticultural production under protected cultivation, in particular, makes abundant use of plastic polymers. Polymers that mostly turn into waste. This study aims to identify the main characteristics and factors affecting the decision of farmers operating in the strawberry production sector to recycle the plastic material used on-farm and quantify the plastic used in relation to the different types of materials used. Data come from one of the Italian most specialized areas in the strawberry sector, Marsala. Main findings show that behind a typical 250-gram basket of strawberries, the production process has generated more than 20 grams of plastic waste, consisting of different polymers. In comparison to what was thought it is exactly in the phase of acquisition of the factors of production, and in their transformation that it is possible to intervene to reduce the quantities of plastic polymers that are introduced into the soil. Our main result adds to previous knowledge that the informed producer (awareness) is the key to solving the problem. Improving environmental sustainability, and creating a circular economy.

title: Salience, Valence, Positions and Voting: International Affairs and British Electoral Politics in the 1960s

description: This article provides a detailed study of the British public and foreign policy issues in the context of electoral politics in the 1960s, a time when the country had to adjust to the shifting geopolitical realities and economic constraints affecting its international role. It analyses several key areas of electoral politics: the general and electoral salience of external and domestic issues; valence evaluations of the parties’ competence on international affairs; and the bivariate and multivariate associations between foreign policy attitudes and voting behaviour in 1964 and 1966. Undertaking detailed analyses of data from quantitative sources relating to public opinion and electoral behaviour, it shows that positional and valence considerations relating to foreign and defence policy were associated with voting for or against Labour at these general elections, even though more generally foreign policy issues were of lower salience than domestic issues during this period of flux and uncertainty in Britain’s international role. The findings contribute to psephological debates concerning the nature of the electoral landscape in the 1960s and the role of external issues at post-war elections. It also extends the scope of scholarly research on the foreign policies and related party politics of the 1964–70 Labour governments.

title: Data set for a method of non-destructive determination of the fresh sugar beet mass between emergence and harvest

description: Up to now, it has not been possible to determine the beet biomass of sugar beet non-destructive dynamically during the growth process. This value is important for the parameterisation of crop growth models. Studies on individual beets show that there is a close relationship between the beet diameter at the widest (thickest) point and the beet biomass. To quantify this relationship data were colleced. The data set contains four sugar beet varieties from the 1990s for three different locations (Müncheberg, Hohenfinow and Dedelow) in Brandenburg, Germany. The data set contains more than 6,700 data records. The measurements were realized in approx. 14-day intervals between rising and harvesting. Different cultivation systems (intensive, organic, extensive) were taken into account additionaly with and without use of irrigation.

title: Long-term data set for soil characteristics on a set aside area in North-East Germany

description: On set-aside areas, which there agricultural used for a long, the soil parameters have a special dynamic. After a long period of anthropogenic use they are moving back to a level typically for the site without any use. For an area on a sandy site (sandy loam-soil, German soil quality index for arable land: 25...35, mean(1988-2017) annual precipitation: 544 mm, mean (1988-2017) annual temperature: 9.3°C) in the Müncheberg area (Federal State of Brandenburg, Germany) for the period 1992-2017 measured values for the most important soil parameters with fast dynamics (NO3, NH4, Nan, soil water) and slow dynamics (pH, Nt, P, K, Mg, Ct) are available for three soil layers (0-30 cm, 30-60 cm and 60-90 cm). Generally these measured values are available annually in spring time. For the years 1992-1996, however, several measurements per year are available also until the end of the vegetation. The area, which has been set-aside since 1992, was used for agriculture until 1991 (recurrent winter rye cultivation). Since 1992 the set-aside area was mulched annually to prevent succession.
