Data from: The chemical basis of a signal of individual identity: Shell pigment concentrations track the unique appearance of Common Murre eggs

Mark E Hauber, Alexander L Bond, Amy-Lee Kouwenberg, Gregory J Robertson, Erpur S Hansen, Mande Holford, Miri Dainson, Alec Luro & James Dale
In group-living species with parental care, the accurate recognition of one’s own young is critical to fitness. Because discriminating offspring within a large colonial group may be challenging, progeny of colonial breeders often display familial or individual identity signals to elicit and receive costly parental provisions from their own parents. For instance, the Common Murre (or Common Guillemot: Uria aalge) is a colonially breeding seabird that does not build a nest and lays and incubates...

Data from: Acherontiscus caledoniae, the earliest heterodont and durophagous tetrapod

Jennifer Clack, Marcello Ruta, Andrew Milner, John Marshall, Timothy Smithson & Keturah Smithson
The enigmatic tetrapod Acherontiscus caledoniae from the Pendleian stage of the Early Carboniferous shows heterodontous and durophagous teeth, representing the earliest known examples of significant adaptations in tetrapod dental morphology. Tetrapods of the Late Devonian and Early Carboniferous (Mississippian), now known in some depth, are generally conservative in their dentition and body morphologies. Their teeth are simple and uniform, being cone-like and sometimes recurved at the tip. Modifications such as keels occur for the first...

Data from: REvoSim: organism-level simulation of macro and microevolution

Russell J. Garwood, Alan R. T. Spencer & Mark D. Sutton
Macroevolutionary processes dictate the generation and loss of biodiversity. Understanding them is a key challenge when interrogating the earth-life system in deep time. Model-based approaches can reveal important macroevolutionary patterns, and generate hypotheses on the underlying processes. Here we present and document a novel model called REvoSim (Rapid Evolutionary Simulator) coupled with a software implementation of this model. The latter is available here as both source code (C++/Qt, GNU General Public License), and as distributables...

Soil moisture, temperature and bulk density and earthworm abundance and biomass along transects from hedges into arable fields, pasture fields, ley strips established in arable fields and arable strips established in pasture fields at a farm in West Yorkshire, England (2015-2017)

M.T. Prendergast-Miller, D.T. Jones & M.E. Hodson
Data are presented on earthworm abundance with distance from hedgerows was recorded for arable fields and pasture leys at Spens farm, the University of Leeds experiment farms, Yorkshire. Sampling was carried out annual from April 2015 to April 2017 with additional sampling in December 2015, and July and October 2016. Pits were excavated and soil hand sorted for earthworms. Mustard solution was then poured into the pit and any emerging earthworms collected. All earthworms were...

Soil moisture, temperature and bulk density and earthworm abundance and biomass along transects in arable fields and ley strips in farms in North Yorkshire, England (2016)

M.T. Prendergast-Miller, D.T. Jones & M.E. Hodson
Data are presented on earthworm abundance with distance from hedgerows was recorded for arable fields and pasture leys at farms at Little Langton, Hutton Wandesley, Overton and Whenby, Yorkshire. Sampling was carried out 12 to 26th May 2016. Pits were excavated and soil hand sorted for earthworms. Mustard solution was then poured into the pit and any emerging earthworms collected. All earthworms were preserved in ethanol for identification using the Sims and Gerard Field studies...

Data from: How has the environment shaped geographical patterns of insect body sizes? A test of hypotheses using sphingid moths

Nicolas Beerli, Florian Baertschi, Liliana Ballesteros-Mejia, Ian J. Kitching & Jan Beck
Aim: We mapped the geographical pattern of body sizes in sphingid moths and investigated latitudinal clines. We tested hypotheses concerning their possible environmental control, i.e., effects of temperature (negative: temperature size rule or Bergmann’s rule; positive: converse Bergmann rule), food availability, robustness to starvation during extreme weather, and seasonality. Location: Old World and Australia/Pacific region Methods: Body size data of 950 sphingid species were compiled and related to their distribution maps. Focusing on body length,...

Data from: Early consequences of allopolyploidy alter floral evolution in Nicotiana (Solanaceae)

Elizabeth W. McCarthy, Jacob B. Landis, Amelda Kurti, Amber J. Lawhorn, Mark W. Chase, Sandra Knapp, Steven C. Le Comber, Andrew R. Leitch & Amy Litt
Background: Polyploidy has played a major role in angiosperm evolution. Previous studies have examined polyploid phenotypes in comparison to their extant progenitors, but not in context of predicted progenitor phenotypes at allopolyploid origin. In addition, differences in the trends of polyploid versus diploid evolution have not been investigated. We use ancestral character-state reconstructions to estimate progenitor phenotype at allopolyploid origin to determine patterns of polyploid evolution leading to morphology of the extant species. We also...
