Data from: Breeding bird species diversity across gradients of land use from forest to agriculture in Europe

Loss, fragmentation and decreasing quality of habitats have been proposed as major threats to biodiversity world-wide, but relatively little is known about biodiversity responses to multiple pressures, particularly at very large spatial scales. We evaluated the relative contributions of four landscape variables (habitat cover, diversity, fragmentation and productivity) in determining different components of avian diversity across Europe. We sampled breeding birds in multiple 1-km2 landscapes, from high forest cover to intensive agricultural land, in eight...

Data from: Quantifying and modelling decay in forecast proficiency indicates the limits of transferability in land-cover classification

Yoni Gavish, Jerome O’Connell, Tim G. Benton & Jerome O'Connell
1. The ability to provide reliable projections for the current and future distribution patterns of land-covers is fundamental if we wish to protect and manage our diminishing natural resources. Two inter-related revolutions made map productions feasible at unprecedented resolutions- the availability of high-resolution remotely-sensed data and the development of machine-learning algorithms. However, the ground-truth data needed for training models is in most cases spatially and temporally clustered. Therefore, map production requires extrapolation of models from...

Data from: Spatiotemporal scaling of plant species richness and functional diversity in a temperate semi-natural grassland

Hannah J. White, W. Ian Montgomery, Robin J. Pakeman & Jack J. Lennon
The accumulation of biodiversity in space and time has been modelled extensively using the species-area relationship and the species-time relationship, respectively. Recently, these models have been combined into time-area curves in order to investigate spatiotemporal scaling of species richness. This study expands on previous research by applying these spatiotemporal models to functional diversity. Understanding spatiotemporal dynamics of ecological traits is important due to their crucial role in ecosystem functioning and mediating species responses to environmental...

Data from: An efficient method to exploit LiDAR data in animal ecology

Simone Ciuti, Henriette Tripke, Peter Antkowiak, Ramiro Silveyra Gonzalez, Carsten F. Dormann & Marco Heurich
1. Light detection and ranging (LiDAR) technology provides ecologists with high-resolution data on three-dimensional vegetation structure. Large LiDAR datasets challenge predictive ecologists, who commonly simplify point clouds into structural attributes (namely LiDAR-based metrics such as canopy height), which are used as predictors in ecological models, potentially with loss of relevant information. 2. We illustrate an efficient alternative approach to reduce the dimensionality of LiDAR data that aims at minimal data filtering with no a priori...

Data from: Low fossilization potential of keratin protein revealed by experimental taphonomy

Evan T. Saitta, Chris Rogers, Richard A. Brooker, Geoffrey D. Abbott, Sumit Kumar, Shane S. O'Reilly, Paul Donohoe, Suryendu Dutta, Roger E. Summons & Jakob Vinther
Recent studies have suggested the presence of keratin in fossils dating back to the Mesozoic. However, ultrastructural studies revealing exposed melanosomes in many fossil keratinous tissues suggest that keratin should rarely, if ever, be preserved. In this study, keratin's stability through diagenesis was tested using microbial decay and maturation experiments on various keratinous structures. The residues were analysed using pyrolysis-gas chromatography-mass spectrometry and compared to unpublished feather and hair fossils and published fresh and fossil...

Data from: An early chondrichthyan and the evolutionary assembly of a shark body plan

Michael I. Coates, John A. Finarelli, Ivan J. Sansom, Plamen S. Andreev, Katharine E. Criswell, Kristen Tietjen, Mark L. Rivers & Patrick J. La Riviere
Although relationships among the major groups of living gnathostomes are well established, the relatedness of early jawed vertebrates to modern clades is intensely debated. Here, we provide a new description of Gladbachus, a Middle Devonian (Givetian ~385-million-year-old) stem chondrichthyan from Germany, and one of the very few early chondrichthyans in which substantial portions of the endoskeleton are preserved. Tomographic and histological techniques reveal new details of the gill skeleton, hyoid arch and jaws, neurocranium, cartilage,...

Data from: Enhancing the diversity of breeding invertebrates within field margins of intensively managed grassland: effects of alternative management practices

Rochelle A. Fritch, Helen Sheridan, John A. Finn, Stephen McCormack & Daire Ó HUallacháin
Severe declines in biodiversity have been well documented for many taxonomic groups due to intensification of agricultural practices. Establishment and appropriate management of arable field margins can improve the diversity and abundance of invertebrate groups; however, there is much less research on field margins within grassland systems. Three grassland field margin treatments (fencing off the existing vegetation “fenced”; fencing with rotavation and natural regeneration “rotavated” and; fencing with rotavation and seeding “seeded”) were compared to...
