Data from: A barrier island perspective on species-area-relationships

Christoph Scherber, Hagen Andert, Rolf Niedringhaus & Teja Tscharntke
Predictions of species richness by island area are a classical cornerstone in ecology, while the specific features of barrier islands have been little appreciated. Many shorelines are occupied by barrier islands, which are shaped by offshore sedimentation processes and annual storm tide events. Hence, the appearance of these islands may vary between years if they are not protected by dykes. Here, we analyzed more than 2,990 species across 36 taxonomic groups (including vertebrates, invertebrates and...

Data from: Ontogenetic resource utilization and migration reconstruction with δ13C values of essential amino acids in the Cynoscion acoupa otolith

Kim Vane, Thomas Larsen, Barbara M. Scholz-Böttcher, Bernd Kopke & Werner Ekau
1. With the increasing anthropogenic impacts on fish habitats, it has become more important to understand which primary resources sustain fish populations. This resource utilization can differ between fish life stages and individuals can migrate between habitats in search of resources. Such lifetime information is difficult to obtain due to the large spatial and temporal scales of fish behaviour. The otolith organic matrix has the potential to indicate this resource utilization and migration with δ13C...

Data from: Trait correlation network analysis identifies biomass allocation traits and stem specific length as hub traits in herbaceous perennial plants

Michael Kleyer, Juliane Trinogga, Miguel A. Cebrián-Piqueras, Anastasia Trenkamp, Camilla Fløjgaard, Rasmus Ejrnæs, Tjeerd J. Bouma, Vanessa Minden, Martin Maier, Jasmin Mantilla-Contreras, Dirk C. Albach, Bernd Blasius & Rasmus Ejrnaes
Correlations among plant traits often reflect important trade‐offs or allometric relationships in biological functions like carbon gain, support, water uptake, and reproduction that are associated with different plant organs. Whether trait correlations can be aggregated to “spectra” or “leading dimensions,” whether these dimensions are consistent across plant organs, spatial scale, and growth forms are still open questions. To illustrate the current state of knowledge, we constructed a network of published trait correlations associated with the...

Data from: Trait patterns of epiphytes compared to other plant life forms along a tropical elevation gradient

David Schellenberger Costa, Gerhard Zotz, Andreas Hemp & Michael Kleyer
Compared to other plant life forms, epiphytes remain understudied. Understanding the responses of epiphytes to changing environmental conditions is necessary to predict changes in ecosystem functioning especially in subtropical and tropical regions. We investigated the functional traits of epiphytes along a large elevation gradient on Mount Kilimanjaro, Tanzania. We measured traits of co-occurring trees and terrestrial non-tree life forms, and compared changes in community-weighted means of traits (CWM) and trait spread, the range of observed...

Data from: Effects of sample fixation on specimen identification in biodiversity assemblies based on proteomic data (MALDI-TOF)

Sven Rossel & Pedro Martínez Arbizu
Recently, MALDI-TOF mass spectrometry has been used to reliably identify taxonomically difficult harpacticoid copepods from sediment samples. In agreement with former studies, a negative impact of short storage periods was stated. Other studies reported inferior mass spectra quality from samples fixated in varying ethanol concentrations. Therefore, sediment samples from a mudflat sampling site in the North Sea were stored under different temperature conditions to explore a possible storage effect. Samples were fixated with either 70%...

Data from: Genome-wide patterns of transposon proliferation in an evolutionary young hybrid fish

Stefan Dennenmoser, Fritz J. Sedlazeck, Michael C. Schatz, Janine Altmüller, Matthias Zytnicki & Arne W. Nolte
Hybridization can induce transposons to jump into new genomic positions, which may result in their accumulation across the genome. Alternatively, transposon copy numbers may increase through non-allelic (ectopic) homologous recombination in highly repetitive regions of the genome. The relative contribution of transposition bursts versus recombination-based mechanisms to evolutionary processes remains unclear because studies on transposon dynamics in natural systems are rare. We assessed the genome-wide distribution of transposon insertions in a young hybrid lineage (“invasive...

Data from: Nocturnal departure timing in songbirds facing distinct migratory challenges

Florian Müller, Cas Eikenaar, Zoe J. Crysler, Philip D. Taylor & Heiko Schmaljohann
1. Most migratory songbirds travel between their breeding areas and wintering grounds through a series of nocturnal flights. The timing of their departures defines the potential flight duration and thus the distance covered during a migratory night. Yet, migratory songbirds show substantial variation in their nocturnal departure timing. 2. With this study we aim to assess whether the respective challenges of the migration route, namely its distance and nature, help to explain this variation. 3....

Data from: Spatial heterogeneity in species composition constrains plant community responses to herbivory and fertilization

Cleland, Scott Collins, Philip A. Fay, Jennifer Firn, Nicole Hagenah, Yann Hautier, Oscar Iribarne, Johannes M.H. Knops, Rebecca L. McCulley, Andrew MacDougall, Joslin L. Moore, John W. Morgan, Brent Mortensen, Kimberly J. La Pierre … & Johannes M. H. Knops
Environmental change can result in substantial shifts in community composition. The associated immigration and extinction events are likely constrained by the spatial distribution of species. Still, studies on environmental change typically quantify biotic responses at single spatial (time series within a single plot) or temporal (spatial beta-diversity at single time points) scales, ignoring their potential interdependence. Here, we use data from a global network of grassland experiments to determine how turnover responses to two major...

Data from: Potential age differences in the migratory behaviour of a nocturnal songbird migrant during autumn and spring

Heiko Schmaljohann, Florian Müller, Thomas Klinner & Cas Eikenaar
In migratory songbirds, older individuals are thought to be more efficient migrants than younger individuals. Age-specific differences in migratory efficiency have been reported mainly in respect of arrival timing, energy stores, rate of energy accumulation, departure behaviour, and departure direction. Yet, these traits were rarely assessed simultaneously in a single species. We further lack information whether age-specific differences in behavioural traits present in autumn still manifest to the same degree in spring. Here we used...

Data from: Interspecific competition alters leaf stoichiometry in 20 grassland species

Jordan Guiz, Anne Ebeling, Nico Eisenhauer, Nina Hacker, Lionel Hertzog, Yvonne Oelmann, Christiane Roscher, Cameron Wagg & Helmut Hillebrand
The extensive use of traits in ecological studies over the last few decades to predict community functions has revealed that plant traits are plastic and respond to various environmental factors. These plant traits are assumed to predict how plants compete and capture resources. Variation in stoichiometric ratios both within and across species reflects resource capture dynamics under competition. However, the impact of local plant diversity on species-specific stoichiometry remains poorly studied. Here, we analyze how...
