Polychlorinated biphenyls (PCB), chlorobenzenes (CB) and organochlorine pesticides (OC) data from rivers [LOIS]

D. Leach, A. Meharg, J. Wright, N. Bachiller-Jareno, I. Tindall & R. Moore
Polychlorinated biphenyls (PCB), chlorobenzenes (CB) and organochlorine pesticides (OC) data from river water collected at various sites within the Humber catchment area as part of the Land Ocean Interaction Study project (LOIS). Data were collected at regular weekly intervals and intermittently during periods of high flows. All sites were samples from early 1994 to the end of 1996 except for O12, which was sampled from November 1994 till November 1996. The sampling was carried out...

Visible leaf injury of Trifolium repens versus Lolium perenne after ozone exposure in solardomes

F. Hayes, G. Mills & M. Ashmore
The dataset consists of proportions of ozone injured or senesced leaves from a study which investigated how the presence of competing species in a community affects these two common responses to ozone. Monocultures and mixtures of Trifolium repens and Lolium perenne were grown in large containers and were exposed in solardomes to either a rural episodic ozone profile (AOT40 (Accumulated Ozone Threshold exposure of 40 parts per billion) of 12.86 ppm h) or control conditions...

Triazine, organophosphate and pyrethroid (TOP) pesticide data from rivers [LOIS]

A. House, D. Leach, N. Bachiller-Jareno, I. Tindall & R. Moore
Triazine, organophosphate and pyrethroid (TOP) pesticide data from river water collected at various sites within the Humber catchment area as part of the Land Ocean Interaction Study project (LOIS).. Water samples were collected weekly and during storm periods between 1994 and 1996. The unfiltered samples were extracted on the day of collection using solid-phase-extraction (SPE), the SPE cartridges stored overnight at 4 degreesC and then transported to the Institute of Freshwater Ecology (IFE), Wareham for...

Data from: Hybridization facilitates evolutionary rescue

Rike B. Stelkens, Michael A. Brockhurst, Gregory D. D. Hurst & Duncan Greig
The resilience of populations to rapid environmental degradation is a major concern for biodiversity conservation. When environments deteriorate to lethal levels, species must evolve to adapt to the new conditions to avoid extinction. Here, we test the hypothesis that evolutionary rescue may be enabled by hybridization, because hybridization increases genetic variability. Using experimental evolution, we show that interspecific hybrid populations of Saccharomyces yeast adapt to grow in more highly degraded environments than intraspecific and parental...

Data from: The effect of hybrid transgression on environmental tolerance in experimental yeast crosses

Rike B. Stelkens, Mike A. Brockhurst, Gregory D. D. Hurst, Eric L. Miller, Duncan Greig, R. B. Stelkens, G. D. D. Hurst, M. A. Brockhurst, E. L. Miller & D. Greig
Evidence is rapidly accumulating that hybridization generates adaptive variation. Transgressive segregation in hybrids could promote the colonization of new environments. Here, we use an assay to select hybrid genotypes that can proliferate in environmental conditions beyond the conditions tolerated by their parents, and we directly compete them against parental genotypes in habitats across environmental clines. We made 45 different hybrid swarms by crossing yeast strains (both Saccharomyces cerevisiae and S. paradoxus) with different genetic and...

Biomass of Trifolium repens versus Lolium perenne after ozone exposure in solardomes

F. Hayes, G. Mills & M. Ashmore
The data are biomass measurements from an ozone exposure experiment, during which Trifolium repens and Lolium perenne were exposed as both monocultures and two-species mixtures to an episodic rural ozone regime in large, well-watered containers within solardomes for 12 weeks. Treatments were elevated ozone (AOT40 (Accumulated Ozone Threshold exposure of 40 parts per billion) of 12.86 ppm h) or control conditions (AOT40 of 0.02 ppm h). Measurements were dry weight, with a cutting height of...

Field measurements of pH, conductivity and temperature data from rivers [LOIS]

D. Leach, A. Pinder, P. Wass, N. Bachiller-Jareno, I. Tindall & R. Moore
On site measurements of pH, conductivity and temperature for thirteen sites in the Humber catchment and three sites in the Tweed catchment within the period 1994 to 1997 as part of the Land Ocean Interaction Study project (LOIS). Sites were sampled at regular weekly intervals and more intermittently during high flows (on average an extra sampling once a month per site). Samples were obtained using a wide neck PTFE bottle in a plastic covered bottle...

Trace element data from rivers [LOIS]

D. Leach, M. Neal, C.J. Smith, N. Bachiller-Jareno, I. Tindall & R. Moore
Discrete data for trace elements for both the dissolved and acid available fractions for thirteen core sites in the Humber catchment over the period 1993 to 1997 and for three sites from the Tweed catchment over the period 1994 to 1997. Part of the Land Ocean Interaction Study project (LOIS). Trace elements measured were: Aluminium (Al), Antimony (Sb), Arsenic (As), Barium (Ba), Beryllium (Be), Boron (B), Cadmium (Cd), Cerium (Ce), Chromium (Cr), Cobalt (Co), Copper...

Continuous measurements of temperature, pH, conductivity and dissolved oxygen in rivers [LOIS]

D. Leach, A. Pinder, P. Wass, N. Bachiller-Jareno, I. Tindall & R. Moore
Continuous measurements of temperature, pH, conductivity and dissolved oxygen from river water at ten sites located within the rivers Swale, Derwent, Aire, Calder, Trent, Ouse and Nidd. Part of the Land Ocean Interaction Study (LOIS) project. Hydrolab H20 water quality monitors were installed at ten sites and used to log water temperature, pH, conductivity and dissolved oxygen between 1994 and 1997. Data were collected continuously at 30 minute intervals (for periods of variable lengths depending...

Data from: A rapid and cost-effective quantitative microsatellite genotyping protocol to estimate intraspecific competition in protist microcosm experiments

Ewan J. A. Minter, Chris D. Lowe, Michael A. Brockhurst & Phillip C. Watts
High levels of intra-specific variation are commonly observed in natural microbial populations, yet the consequences of this variation for ecological and evolutionary processes remains poorly understood. Protists are excellent experimental models for investigating fundamental and applied questions in ecology and evolution, but studying intra-specific variation remains a challenge due to a lack of molecular resources to aid in quantifying and distinguishing strains during experiments. Here we present a molecular method, quantitative microsatellite genotyping, to accurately...

Data from: Individual variation in the oxidative costs of personality traits

Kathryn Arnold, Katherine Herborn, Aileen Adam, Lucille Alexander, Kathryn E. Arnold & Katherine A. Herborn
1.‘Personality traits’ are behavioural differences between individuals that are stable within individuals. Different combinations of personality traits can correlate with fitness variation but the mechanisms remain unclear. There is the suggestion that personality reflects variation in physiology. For example, ‘fast’ (bold, active, fast exploring) individuals are predicted to maintain a higher metabolic rate than ‘slow’ animals. A raised metabolic rate can result in a proliferation of reactive oxygen species (ROS) which, if unchecked, cause oxidative...

Data from: Polylysogeny magnifies competitiveness of a bacterial pathogen in vivo

Nicola Burns, Chloe E. James & Ellie Harrison
The rise of next generation sequencing is revealing a hidden diversity of temperate phages within the microbial community. While a handful of these phages have been well characterized, for the vast majority, the role of phage carriage, and especially multiple phage carriage, is poorly understood. The Liverpool Epidemic Strain of Pseudomonas aeruginosa is an aggressive pathogen in Cystic Fibrosis lung infections that has recently been found to contain several unique prophages within its genome. Here...
