Soil properties and soil greenhouse gas emissions in biochar-amended bioenergy soils incubated under controlled laboratory conditions

S.D.C. Case, N.P. McNamara, D.S. Reay, J.S. Chaplow & J. Whitaker
Data from an investigation of the effects of biochar application to soil on greenhouse gas emissions using soil from a bioenergy crop (Miscanthus X. giganteus). Data include physical (bulk density) and chemical analyses of the soil (total carbon (C) and nitrogen (N), extractable ammonium and nitrate), and greenhouse gas (GHG) emissions (carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O)) during incubations. Data were collected during two incubation experiments investigating the effects of temperature, soil...

Data from: Increasing temperature, not mean temperature, is a cue for avian timing of reproduction

Sonja Verena Schaper, Alistair S. Dawson, Peter J. Sharp, Phillip Gienapp, Samuel P. Caro, Marcel E. Visser & Alistair Dawson
Timing of reproduction in temperate zone birds is strongly correlated with spring temperature, with an earlier onset of breeding in warmer years. Females adjust their laying between years to be synchronized with local food sources and thereby optimize reproductive output. However, climate change currently disrupts the link between predictive environmental cues and spring phenology. To investigate direct effects of temperature on the decision to lay, and its genetic basis, we used pairs of Great Tits...

United Kingdom Butterfly Monitoring Scheme: collated indices 2012

M. Botham, D. Roy, T. Brereton, I. Middlebrook & Z. Randle
Collated indices are a relative measure of butterfly abundance across monitored sites in the UK, calculated from data collected by the UK Butterfly Monitoring Scheme (UKBMS). Collated indices are calculated annually for each individual butterfly species that has been recorded on five or more sites in that year. Based on this criterion collated indices have been calculated for the entire UKBMS time series from 1976 to the current year for the majority of species. For...

Data from: Evolutionary significance of the invasion of introduced populations into the native range of Meconopsis cambrica

Francisco J Valtue├▒a, Christopher D Preston & Joachim W Kadereit
The long history of the deliberate or accidental, human-mediated dispersal of flowering plants has led to the introduction of foreign genotypes of many species into areas of Europe hitherto occupied by potentially distinct native populations. Studies of the genetic and evolutionary consequences of such changes are handicapped by the difficulty of identifying the surviving native populations of many species in the absence of clear morphological differences. We investigated the relationship between putative native and introduced...

ITE Land Classification of Great Britain 1990

R.G.H. Bunce, C.J. Barr, R.T. Clarke, D.C. Howard & A.M.J. Lane
The Land Classification 1990 is a classification of Great Britain into a set of 32 environmental strata, termed land classes, to be used as a basis for ecological survey, originally developed by the Institute of Terrestrial Ecology (ITE) in the late 1970s. The strata were created from the multivariate analysis of 75 environmental variables, including climatic data, topographic data, human geographical features and geology data. The Land Classification can be used to stratify a wide...

Root data from Climoor fieldsite in Clocaenog Forest

A. Sowerby & B.A. Emmett
This dataset includes all measurements of roots from the Climoor fieldsite in the Clocaenog Forest. The data spans three periods: 2003-2004, 2008 and 2011. In 2003 and 2004, 5cm x 15cm plastic root cores were measured, and roots manually picked out the soil. In 2008, root biomass was determined by sieving and washing. In 2011, root biomass, density and length was also determined using sieving and washing. However, the methods used in each of the...

Standardised Precipitation Index time series for Integrated Hydrological Units Hydrometric Areas (1961-2012)

M. Tanguy, F. Kral., M. Fry, C. Svensson & J. Hannaford
Standardised Precipitation Index (SPI) data for Integrated Hydrological Units (IHU) Hydrometric Areas (Kral et al. [1]). SPI is a drought index based on the probability of precipitation for a given accumulation period as defined by McKee et al. [2]. SPI is calculated for different accumulation periods: 1, 3, 6, 12, 18, 24 months. Each of these is in turn calculated for each of the twelve calendar months. Note that values in monthly (and for longer...

High-resolution global topographic index values

T.R. Marthews, S.J. Dadson, B. Lehner, S. Abele & N. Gedney
The topographic index is a hydrological quantity describing the propensity of the soil at landscape points to become saturated with water as a result of topographic position (i.e. not accounting for other factors such as climate that also affect soil moisture but are accounted for separately). Modern land surface models require a characterisation of the land surface hydrological regime and this parameter allows the use of the TOPMODEL hydrological model to achieve this .This Geographic...

S. Dreier, J.W. Redhead, I. Warren, A.F.G. Bourke, M.S. Heard, W.C. Jordan, S. Sumner, J. Wang & C. Carvell
Geographic distances between pairs of wild bumblebee colonies across an agricultural landscape centred on the Hillesden Estate, Buckinghamshire, UK. Colony locations were estimated using the foraging locations of workers sampled in summer 2011, genotyped and grouped into full-sib families. The spatial structure of five Bombus species (Bombus terrestris, B. lapidarius, B. pascuorum, B. hortorum and B. ruderatus) was determined, with inter-colony distances varying from 7 to 5264 metres. Data were collected as part of a...

Integrated Hydrological Units of the United Kingdom: Hydrometric Areas with Coastline

This dataset is part of Integrated Hydrometric Units (IHU) of the UK. Hydrometric Areas are used to organise river flow measurement and hydrometric data collection in the UK. Hydrometric Areas are either integral river catchments having one or more outlets to the sea or tidal estuary, or they may include several contiguous river catchments having topographical similarity but separate tidal outlets. In mainland Britain they are numbered from 1 to 97 in clockwise order around...
