Dissolved rhenium and other dissolved ions in Alpine catchments of the Erlenbach and Vogelbach (Switzerland) and the East River (Colorado, USA)

Robert G Hilton & Mathieu Dellinger
The measurements and data contained here were obtained to study the chemical weathering of sedimentary rocks, and more specifically the oxidation of rock organic carbon and the associated release of CO2. The primary aim was to better understand the production and mobility of the trace element rhenium during weathering, because this element has been proposed as a proxy for rock organic carbon oxidation. The study focused on three Alpine catchments that drain sedimentary rocks, which...

Permian–Triassic phylogenetic and morphologic evolution of rhynchonellide brachiopods

Zhen Guo, Zhong-Qiang Chen, A. T. Harper David & Yuangeng Huang
The Rhynchonellida is a major group of brachiopods that survived the “big five” mass extinctions and flourished after the Permian-Triassic (P-Tr) crisis. However, phylogenetic and character evolution in the Rhynchonellida across the P-Tr transition is poorly understood. In view of the widespread homoplasy across this order, we employ a tip-dated Bayesian analysis to reconstruct phylogenetic relationships for Late Permian–Triassic rhynchonellides. The same data were also analyzed using three other methods: undated Bayesian, equal-weighting, and implied-weighting...

Global maps of current (1979-2013) and future (2061-2080) habitat suitability probability for 1,485 European endemic plant species

Robin Pouteau, Idoia Biurrun, Caroline Brunel, Milan Chytrý, Wayne Dawson, Franz Essl, Trevor Fristoe, Rense Haveman, Carsten Hobohm, Florian Jansen, Holger Kreft, Jonathan Lenoir, Bernd Lenzner, Carsten Meyer, Jesper Erenskjold Moeslund, Jan Pergl, Petr Pyšek, Jens-Christian Svenning, Wilfried Thuiller, Patrick Weigelt, Thomas Wohlgemuth, Qiang Yang & Mark Van Kleunen
Aims: The rapid increase in the number of species that have naturalized beyond their native range is among the most apparent features of the Anthropocene. How alien species will respond to other processes of future global changes is an emerging concern and remains largely misunderstood. We therefore ask whether naturalized species will respond to climate and land-use change differently than those species not yet naturalized anywhere in the world. Location: Global Methods: We investigated future...

RNA-seq of Arabidopsis root growth responses to mechanical impedance

Keith Lindsey, Amy Jacobsen, Jian Xu, Jennifer Topping & George Jervis
1. The growth and development of root systems, essential for plant performance, is influenced by mechanical properties of the substrate in which the plants grow. Mechanical impedance, such as by compacted soil, can reduce root elongation and limit crop productivity. 2. To understand better the mechanisms involved in plant root responses to mechanical impedance stress, we investigated changes in the root transcriptome and hormone signalling responses of Arabidopsis to artificial root barrier systems in vitro....

Carbon dioxide flux and isotopic composition from sedimentary rock weathering, Draix-Bleone Critical Zone Observatory, France

G. Soulet, R.G. Hilton, M.H. Garnett & S. Klotz
The measurements and data contained here were obtained to study the release of carbon dioxide during the chemical weathering of sedimentary rocks. The primary aim of the research was to explore how these CO2 fluxes were related to environmental parameters (temperature, hydrology). Weathering of sedimentary rocks can result in CO2 release from the oxidation of rock organic carbon oxidation, but also due to the oxidation of sulfide minerals, production of sulfuric acid and subsequent release...

Supplementary information for integrating sequence capture and restriction-site associated DNA sequencing to resolve recent radiations of Pelagic seabirds

Joan Ferrer-Obiol, Helen F. James, R. Terry Chesser, Vincent Bretagnolle, Jacob González-Solís, Julio Rozas, Marta Riutort & Andreanna J. Welch
The diversification of modern birds has been shaped by a number of radiations. Rapid diversification events make reconstructing the evolutionary relationships among taxa challenging due to the convoluted effects of incomplete lineage sorting (ILS) and introgression. Phylogenomic datasets have the potential to detect patterns of phylogenetic incongruence, and to address their causes. However, the footprints of ILS and introgression on sequence data can vary between different phylogenomic markers at different phylogenetic scales depending on factors...

High resource overlap and small dietary differences are widespread in food-limited warbler communities

Cody Kent, Kyu Huh, Sarah Hunter, Kathryn Judson, Luke Powell & Thomas Sherry
Although both interspecific competition and coexistence mechanisms are central to ecological and evolutionary theory, past empirical studies have generally focused on simple (two-species) communities over short time periods. Experimental tests of these species interactions are challenging in complex study systems. Moreover, a number of studies of ‘imperfect generalists’, consistent with Liem’s Paradox, raise questions about the ability of evolved species differences to effectively partition niche space when resources vary considerably across the annual cycle. Here...

Phylogenetic signal and bias in paleontology

Robert Asher & Martin Smith
An unprecedented amount of evidence now illuminates the phylogeny of living mammals and birds on the Tree of Life. We use this tree to measure phylogenetic value of data typically used in paleontology (bones and teeth) from six datasets derived from five published studies. We ask three interrelated questions: 1) Can these data adequately reconstruct known parts of the Tree of Life? 2) Is accuracy generally similar for studies using morphology, or do some morphological...

Comparative biogeography and the evolution of population structure for bottlenose and common dolphins in the Indian Ocean

Howard Gray
Abstract Aim: In the marine environment, where there are few physical boundaries to gene flow, there is often nevertheless intraspecific diversity with consequences for effective conservation and management. Here we compare two closely related dolphin species with a shared distribution in the Indian Ocean (IO) to better understand the biogeographic drivers of their population structure. Location: Global oceans and seas with a focus on the Indian Ocean Taxon: Tursiops sp. and Delphinus sp. Methods: Bayesian,...

DOC nutrient addition experiments

Catherine Moody & Fred Worrall
Peatlands are typically rich in labile dissolved and particulate organic matter (DOM and POM) but poor in nutrients; as these peatland waters flow through a catchment they mix with more nutrient-rich but organic matter (OM) poor waters. These new sources of nutrients may lead to increased OM degradation, driving further release of CO2 to the atmosphere. The aim of this study was to discover if the addition of nutrients changed the rates of peat-derived dissolved...

Numerical model output data on the interaction of flow with a permeable bed and biofilms

G. H. Sambrook Smith, R. J. Hardy & S. Sinha
The data contains numerical model simulations designed to assess the influence of a) a permeable bed on flow structures above and within the pore spaces of a bed and b) a biofilm streamer on the free flow structure. For the former the data relates to a novel Computational Fluid Dynamics (CFD) model that is able to simulate flow both in the boundary layer flow and Brinkman layer. This allows simultaneous predictions of surface and subsurface...

Supplementary information for Paleoceanographic changes in the late Pliocene promoted rapid diversification in pelagic seabirds

Joan Ferrer Obiol, Helen F. James, R. Terry Chesser, Vincent Bretagnolle, Jacob González-Solís, Julio Rozas, Andreanna J. Welch & Marta Riutort
Aim: Paleoceanographic changes can act as drivers of diversification and speciation, even in highly mobile marine organisms. Shearwaters are a group of globally distributed and highly mobile pelagic seabirds. Despite a recent well resolved phylogeny, shearwaters have controversial species limits, and show periods of both slow and rapid diversification. Here, we explore the role of paleoceanographic changes on the diversification and speciation in these highly mobile pelagic seabirds. We investigate shearwater biogeography and the evolution...

Global impacts of climate change on avian functional diversity

Peter Stewart, Alke Voskamp, Luca Santini, Matthias Biber, Adam Devenish, Christian Hof, Stephen Willis & Joseph Tobias
Climate change is predicted to drive geographical range shifts, leading to fluctuations in species richness worldwide. However, the effect of these changes on functional diversity remains unclear, in part because comprehensive species-level trait data are generally lacking at global scales. Here we use morphometric and ecological traits for 8268 bird species to estimate the impact of climate change on avian functional diversity (FD). We show that future bird assemblages are likely to undergo substantial shifts...

Pacific Introduced Flora (PacIFLora)

Michael Wohlwend, Dylan Craven, Patrick Weigelt, Hanno Seebens, Marten Winter, Holger Kreft, Wayne Dawson, Franz Essl, Mark Van Kleunen, Jan Pergl, Petr Pyšek, James Space, Philip Thomas & Tiffany Knight
The Pacific region has the highest density of naturalized plant species worldwide, which makes it an important area for research on the ecology, evolution and biogeography of biological invasions. While different data sources on naturalized plant species exist for the Pacific, there is no taxonomically and spatially harmonized database available for different subsets of species and islands. A comprehensive, accessible database containing the distribution of naturalized vascular plant species in the Pacific will enable new...

Limitations of using surrogates for behaviour classification of accelerometer data: refining methods using random forest models in Caprids

Eleanor Dickinson, Joshua Twining, Rory Wilson, Philip Stephens, Jennie Westander, Nikki Marks & Michael Scantlebury
Animal-attached devices can be used on cryptic species to measure their movement and behaviour, enabling unprecedented insights into fundamental aspects of animal ecology and behaviour. However, direct observations of subjects are often still necessary to translate biologging data accurately into meaningful behaviours. As many elusive species cannot easily be observed in the wild, captive or domestic surrogates are typically used to calibrate data from devices. However, the utility of this approach remains equivocal. Here, we...

Detecting genetic signals of selection in heavily bottlenecked reindeer populations by comparing parallel founder events

Menno De Jong, Fiona Lovatt & Rus Hoelzel
Founder populations are of special interest to both evolutionary and conservation biologists, but the detection of genetic signals of selection in these populations is challenging due to their demographic history. Geographically separated founder populations likely subjected to similar selection pressures provide an ideal but rare opportunity to overcome these challenges. Here we take advantage of such a situation generated when small, isolated founder populations of reindeer were established on the island of South Georgia, and...

Projected climatic changes lead to biome changes in areas of previously constant biome

Brian Huntley, Judy Allen, Matthew Forrest, Thomas Hickler, Ralf Ohlemüller, Joy Singarayer & Paul Valdes
Aim: Recent studies in southern Africa identified past biome stability as an important predictor of biodiversity. We aimed to assess the extent to which past biome stability predicts present global biodiversity patterns, and the extent to which projected climatic changes may lead to eventual biome changes in areas with constant past biome. Location: Global. Taxon: Spermatophyta; terrestrial vertebrates. Methods: Biome constancy was assessed and mapped using results from 89 dynamic global vegetation model simulations, driven...

Dissolved methane concentrations in groundwater

M.P. Wilson
This dataset contains dissolved methane concentrations from groundwater in Great Britain, predominantly from England. Data were collated in Microsoft Excel (.xlsx) format from four publicly accessible sources: the British Geological Survey (from Bell et al., 2017), the Environment Agency for England (from the online Water Quality Archive), and local baseline data for the shale gas sites of Preston New Road (from Cuadrilla Resources) and Kirby Misperton (from Third Energy). In total, 2997 dissolved methane concentrations...

South African Tursiops aduncus ddRAD genepop file

Rus Hoelzel
Many marine species exhibit fine-scale population structure despite high mobility and a lack of physical barriers to dispersal, but the evolutionary drivers of differentiation in these systems are generally poorly understood. Here we investigate the potential role of habitat transitions and seasonal prey distributions on the evolution of population structure in the Indo-Pacific bottlenose dolphin, Tursiops aduncus, off South Africa’s coast, using double-digest Restriction-site Associated DNA sequencing (ddRADseq). Population structure was identified between the eastern...

Conformity to Bergmann’s rule in birds depends on nest design and migration

Mark Mainwaring & Sally Street
Ecogeographical rules attempt to explain large-scale spatial patterns in biological traits. One of the most enduring examples is Bergmann’s rule, which states that species should be larger in colder climates due to the thermoregulatory advantages of larger body size. Support for Bergmann’s rule, however, is not consistent across taxonomic groups, raising questions about what factors may moderate its effect. Behaviour may play a crucial, yet so far underexplored, role in mediating the extent to which...

Correlates of substitution rate variation in a robust Procellariiform seabird phylogeny

Andrea Estandia, Terry Chesser, Helen James, Max Levy, Joan Ferrer-Obiol, Vincent Bretagnolle, Jacob González-Solís & Andreanna Welch
Molecular substitution rates vary among branches and can lead to inaccurate reconstructions of evolutionary relationships and obscure the true phylogeny of affected clades. Body mass is often assumed to have a major influence on substitution rate, though other factors such as population size, life history traits, and flight demands are also thought to have an influence. Birds of the order Procellariiformes—which encompasses petrels, storm-petrels and albatrosses—show a striking 900-fold difference in body mass between the...

The role of individual behavioral traits on fishway passage attempt behavior

Angus Lothian & Martyn Lucas
Variations in behavioural traits are widely recognised to drive animal behaviours exhibited within a population. However, information on how behaviour traits influence behaviour in anthropogenically modified habitats is lacking. Many habitats have become highly fragmented as a result of human processes. To mitigate this and improve habitat connectivity, wildlife passes are increasingly employed, with the aim of enabling animals to move freely between habitats. However, wildlife passes (e.g. fishways) are not always effective in achieving...

Characteristics of the naturalized flora of Southern Africa largely reflect the non-random introduction of alien species for cultivation

Ali Omer, Trevor Fristoe, Qiang Yang, Noëlie Maurel, Patrick Weigelt, Holger Kreft, Jonas Bleilevens, Wayne Dawson, Franz Essl, Jan Pergl, Mark Van Kleunen & Petr Pyšek
This dataset contains data on the cultivated alien and native flora of Southern Africa associated with data on geographic origins, growth form, functional traits, and naturalization status extracted from different data sources described in Omer, A. et al. 2021. Characteristics of the naturalized flora of Southern Africa largely reflect the non-random introduction of alien species for cultivation– Ecography. doi: 10.1111/ecog.05669. It is frequently overlooked, however, that patterns in origin, phylogeny, and traits of naturalized alien...
