Understanding how and why rates of evolutionary diversification vary is a central issue in evolutionary biology, ecology and biogeography. The concept of adaptive radiation has attracted much interest, but is metaphorical and verbal in nature, making it difficult to quantitatively compare different evolutionary lineages or geographic regions. In addition, the causes of evolutionary stasis are relatively neglected. Here we review the central concepts in the evolutionary diversification literature and bring these together by proposing a...

Data from: Reindeer trampling promotes vegetation changes in tundra heathlands: results from a simulation experiment

Dagmar Egelkraut, Hélène Barthelemy & Johan Olofsson
This dataset contains all the raw data belonging to the research article 'Reindeer trampling promotes vegetation changes in tundra heathlands: results from a simulation experiment', by Egelkraut, Barthelemy and Olofsson, published in Journal of Vegetation Science. The experiment experimentally simulated various herbivore activities (Defoliation, Moss removal, Fertilization, Trampling, FDT, FDTM) on lightly grazed tundra heath vegetation, in order to determine in what way each of these activities cntributed to change in vegetation community and structure....

AQUACOSM VIMS-Ehux – Core data

Flora Vincent, Guy Schleyer, Constanze Kuhlisch, Celia Marrasé, Rafel Simó, Jorun Egge, Assaf Vardi & Daniella Schatz
The cosmopolitan coccolithophore Emiliania huxleyi is a unicellular alga that forms massive oceanic blooms covering thousands of square kilometers (Tyrrell & Merico 2004). The intricate calcite exoskeleton of E. huxleyi accounts for ~1/3 of total marine CaCO3 production (Monteiro et al. 2016). E. huxleyi blooms are an important source of DMS, which is, by far, the most abundant volatile sulfur compound in the surface ocean and the best studied aerosol precursor (Simó 2001) with a...

Equilibrium in plant functional trait responses to warming is stronger under higher climate variability during the Holocene

Pierre Gaüzère, Lars Iversen, Alistair Seddon, Cyrille Violle & Ben Blonder
Aim.The functional trait composition of plant communities is thought to be largely determined by climate, but relationships between contemporary trait distributions and climate are often weak. Spatial mismatches between trait and climatic conditions are commonly thought to arise from disequilibrium responses to past environmental changes. We here investigated whether current trait-climate disequilibrium were likely to emerge during plant functional responses to Holocene climate warming. Location.North America Time period.14-0Kya Major taxa studied. Terrestrial plants Methods. We...

Palm fruit colours are linked to the broad-scale distribution and diversification of primate colour vision systems

Renske Onstein, Daphne Vink, Jorin Veen, Christopher Barratt, Suzette Flantua, Serge Wich & Daniel Kissling
A long-standing hypothesis in ecology and evolution is that trichromatic colour vision (the ability to distinguish red from green) in frugivorous primates has evolved as an adaptation to detect conspicuous (reddish) fruits. This could provide a competitive advantage over dichromatic frugivores which cannot distinguish reddish colours from a background of green foliage. Here, we test whether the origin, distribution and diversity of trichromatic primates is positively associated with the availability of conspicuous palm fruits, i.e....

Data from: Ecological impact assessments of alien species in Norway

Hanno Sandvik, Olga Hilmo, Snorre Henriksen, Reidar Elven, Per Arvid Åsen, Hanne Hegre, Oddvar Pedersen, Per Anker Pedersen, Heidi Solstad, Vigdis Vandvik, Kristine B. Westergaard, Frode Ødegaard, Sandra Åström, Hallvard Elven, Anders Endrestøl, Øivind Gammelmo, Bjørn Arild Hatteland, Halvor Solheim, Björn Nordén, Leif Sundheim, Venche Talgø, Tone Falkenhaug, Bjørn Gulliksen, Anders Jelmert, Eivind Oug … & Lisbeth Gederaas
Due to globalisation, trade and transport, the spread of alien species is increasing dramatically. Some alien species become ecologically harmful by threatening native biota. This can lead to irreversible changes in local biodiversity and ecosystem functioning, and, ultimately, to biotic homogenisation. We risk-assessed all alien plants, animals, fungi and algae, within certain delimitations, that are known to reproduce in Norway. Mainland Norway and the Arctic archipelago of Svalbard plus Jan Mayen were treated as separate...

Data from: Last Glacial Maximum environmental conditions at Andøya, northern Norway; evidence for a northern ice-edge ecological “hotspot”

Inger Alsos, Per Sjögren, Antony Brown, Ludovic Gielly, Marie Merkel, Aage Paus, Youri Lammers, Mary Edwards, Torbjørn Alm, Melanie Leng, Tomasz Goslar, Catherine Langdon, Jostein Bakke & Willem Van Der Bilt
Andøya on the NW coast of Norway is a key site for understanding the Last Glacial Maximum (LGM) in northern Europe. Controversy has arisen concerning the local conditions, especially about the timing and extent of local glacial cover, maximum July temperatures and whether pine and/or spruce could have grown there. We reviewed all existing data and add newly analysed ancient sedimentary DNA, pollen, macrofossils, geochemistry and stable isotopes from three lake sediment cores from Øvre...

Data from: Spatial covariance of herbivorous and predatory guilds of forest canopy arthropods along a latitudinal gradient

Ondřej Mottl
In arthropod community ecology, species richness studies tend to be prioritized over those investigating patterns of abundance. Consequently, the biotic and abiotic drivers of arboreal arthropod abundance are still relatively poorly known. In this cross-continental study, we employ a theoretical framework in order to examine patterns of covariance among herbivorous and predatory arthropod guilds. Leaf-chewing and leaf-mining herbivores, and predatory ants and spiders, were censused on > 1,000 trees in nine 0.1 ha forest plots....

Exploring protocol bias in airway microbiome studies: One versus two PCR steps and 16S rRNA gene region V3 V4 versus V4

Christine Drengenes, Rune Nielsen, Ingvild Haaland, Harald Wiker & Tomas Eagan
Background: Studies on the airway microbiome have been performed using a wide range of laboratory protocols for high-throughput sequencing of the bacterial 16S ribosomal RNA (16S rRNA) gene. We sought to determine the impact of number of polymerase chain reaction (PCR) steps (1- or 2-steps) and choice of target marker gene region (V3 V4 and V4) on the presentation of the upper and lower airway microbiome. Our analyses included lllumina MiSeq sequencing following three setups:...

Frog tongue segmentation data for a realistic vascular structure in modelling

Ulin Nuha Abdul Qohar, Erik Andreas Hanson, Antonella Zanna Munthe-Kaas & Jan Martin Nordbotten
In the last decade, numerical models have been an increasingly important tool in biological and medical science both for the fundamental understanding of physiology as well as the potential for novel diagnostics and treatments tools in clinical application. In this paper, a nonlinear multi-scale model framework is developed for blood flow distribution in the full vascular system of an organ. We couple a quasi 1D vascular graph model to represent blood flow in larger vessels...

Chemical variations in Quercus pollen as a tool for taxonomic identification: implications for long-term ecological and biogeographical research

Florian Muthreich, Boris Zimmermann, Carlos M. Vila-Viçosa, H. John. B. Birks & Alistair W.R. Seddon
Aim Fossil pollen is an important tool for understanding biogeographic patterns in the past, but the taxonomic resolution of the fossil-pollen record may be limited to genus or even family level. Chemical analysis of pollen grains has the potential to increase the taxonomic resolution of pollen, but present-day chemical variability is poorly understood. This study aims to investigate whether a phylogenetic signal is present in the chemical variations of Quercus L. pollen and to assess...

Data from: Testing macroecological abundance patterns: the relationship between local abundance and range size, range position and climatic suitability among European vascular plants

Maria Sporbert, Petr Keil, Gunnar Seidler, Helge Bruelheide, Ute Jandt, Svetlana Aćić, Idoia Biurrun, Juan Antonio Campos, Andraž Čarni, Milan Chytrý, Renata Custerevska, Jürgen Dengler, Valentin Golub, Florian Jansen, Anna Kuzemko, Jonathan Lenoir, Corrado Marcenò, Jesper Erenskjold Moeslund, Aaron Pérez-Haase, Solvita Rūsiņa, Urban Šilc, Ioannis Tsiripidis, Vigdis Vandvik, Kiril Vassilev, Risto Virtanen … & Erik Welk
Aim: A fundamental question in macroecology centres around understanding the relationship between species’ local abundance and their distribution in geographic and climatic space (i.e. the multi-dimensional climatic space or climatic niche). Here, we tested three macroecological hypotheses that link local abundance to the following range properties: (1) the abundance-range size relationship, (2) the abundance-range centre relationship, and (3) the abundance-suitability relationship. Location: Europe Taxon: Vascular plants Methods: Distribution range maps were extracted from the Chorological...

Life history shifts in an exploited African fish following invasion by a castrating parasite

Nestory Peter Gabagambi, Arne Skorping, Mwita Chacha, Kwendwa Jonathan Kihedu & Adele Mennerat
Evolutionary theory predicts that infection by a parasite that reduces future host survival or fecundity should select for increased investment in current reproduction. In this study we use the cestode Ligula intestinalis and its intermediate fish host Engraulicypris sardella in Wissman Bay, Lake Nyasa (Tanzania) as a model system. Using data about infection of E. sardella fish hosts by L. intestinalis collected for a period of 10 years, we explored whether parasite infection affects the...

The Pantophysin gene and its relationship with survival in Atlantic cod

Håkon Otterå, Torild Johansen, Arild Folkvord, Geir Dahle, Marte Kristine Solvang Bingh, Jon-Ivar Westgaard & Kevin Alan Glover
Distinction between highly migratory Northeast Arctic cod and stationary Norwegian Coastal cod represents an important management issue. They overlap on the same spawning grounds where they are harvested, but display highly different abundences. This necessitates alternative management strategies. The bi-allelic genetic marker, pantophysin (Pan I), has been widely used as a diagnostic marker to discriminate between these two stocks. However, it has been proposed that this locus, or another gene(s) on chromosome 1 where it...

Disentangling direct and indirect effects of habitat fragmentation on wild plants' pollinator visits and seed production

Amparo Lázaro, Francisco Fuster, David Alomar & Orjan Totland
Habitat fragmentation threatens plant and pollinator communities, as well as their interactions. However, the effects of landscape fragmentation on the pollination of wild plant species are not well-understood yet, partly because in fragmented landscapes there are many correlated features (e.g. decreased patch size, increased isolation and patch complexity) whose influences are difficult to disentangle. Using a SEM approach, we assessed the direct and indirect effects of landscape fragmentation (patch size, isolation and complexity, percentage of...

European soil seed bank communities across a climate and land-cover gradient

Jan Plue, Hans Van Calster, Inger Auestad, Sofia Basto, Reneé M. Bekker, Hans Henrik Bruun, Richard Chevalier, Guillaume Decocq, Ulf Grandin, Martin Hermy, Hans Jacquemyn, Anna Jakobsson, Rein Kalamees, Rob H. Marrs, Bryndis Marteinsdóttir, Per Milberg, Robin J. Pakeman, Gareth Phoenix, Ken Thompson, Vigdis Vandvik, Markus Wagner, Sara A.O. Cousins, Ove Eriksson, Jamshid Ghorbani, Małgorzata Jankowska-Błaszczuk … & Alistair G. Auffret
This is the data set used for the publication Buffering effects of soil seed banks on plant community composition in response to land use and climate, published in the journal Global Ecology and Biogeography. Aim. Climate and land use are key determinants of biodiversity, with past and ongoing changes posing serious threats to global ecosystems. Unlike most other organism groups, plant species can possess dormant life-history stages such as soil seed banks, which may help...

Data from: “A cleaner break”: genetic divergence between geographic groups and sympatric phenotypes revealed in ballan wrasse (Labrus bergylta)

Gaute Seljestad, Maria Quintela, Ellika Faust, Kim Halvorsen, Francois Besnier, Eeva Jansson, Geir Dahle, Halvor Knutsen, Carl Andre, Arild Folkvord & Kevin Glover
Capture and long-distance translocation of cleaner fish to control lice infestations on marine salmonid farms has the potential to influence wild populations via overexploitation in source regions, and introgression in recipient regions. Knowledge of population genetic structure is therefore required. We studied the genetics of ballan wrasse, a phenotypically diverse and extensively used cleaner fish, from 18 locations in Norway and Sweden, and from Galicia, Spain. We detected two very distinct genetic groups in Scandinavia,...

Data from: First records of complete annual cycles in water rails Rallus aquaticus show evidence of itinerant breeding and a complex migration system

Terje Lislevand, Steffen Hahn, Sven Rislaa & Martins Briedis
In water rails Rallus aquaticus, northern and eastern populations are migratory while southern and western populations are sedentary. Few details are known about the annual cycle of this elusive species. We studied movements and breeding in water rails from southernmost Norway where the species occurs year-round. Colour-ringed wintering birds occurred only occasionally at the study site in summer, and vice versa. Geolocator tracks revealed that wintering birds (n = 10) migrated eastwards in spring to...

The airway microbiota and exacerbations of COPD

Tomas Eagan, Elise Leiten, Rune Nielsen, Harald Wiker, Per Bakke, Einar Marius Martinsen, Christine Drengenes, Solveig Tangedal & Gunnar Husebø
Aim: To investigate whether the compositionality of the lower airway microbiota predicts later exacerbation risk in persons with COPD in a cohort study. Materials and methods: We collected lower airways microbiota samples by bronchoalveolar lavage and protected specimen brushes, and oral wash samples from 122 participants with COPD. Bacterial DNA was extracted from all samples, before we sequenced the V3-V4 region of the 16S RNA gene. The frequency of moderate and severe COPD exacerbations was...
