Spatial genetic structure (SGS) of plants results from the non-random distribution of related individuals. SGS provides information on gene flow and spatial patterns of genetic diversity within populations. Seed dispersal creates the spatial template for plant distribution. Thus, in zoochorous plants, dispersal mode and disperser behavior might have a strong impact on SGS. However, many studies only report the taxonomic group of seed dispersers, without further details. The recent increase in studies on SGS provides...
Data from: Specific 50-kHz vocalizations are tightly linked to particular types of behavior in juvenile rats anticipating playCandace J. Burke, Theresa M. Kisko, Hilarie Swiftwolfe, Sergio M. Pellis & David R. Euston
Rat ultrasonic vocalizations have been suggested to be either a byproduct of physical movement or, in the case of 50-kHz calls, a means to communicate positive affect. Yet there are up to 14 distinct types of 50-kHz calls, raising issues for both explanations. To discriminate between these theories and address the purpose for the numerous 50-kHz call types, we studied single juvenile rats that were waiting to play with a partner, a situation associated with...
Data from: LiDAR-derived canopy structure supports the more-individuals hypothesis for arthropod diversity in temperate forestsJörg Müller, Roland Brandl, Martin Brändle, Bernhard Förster, Bruno Cancian De Araujo, Martin M. Gossner, Alexander Ladas, Martin Wagner, Mark Maraun, Peter Schall, Stefan Schmidt, Marco Heurich, Simon Thorn & Sebastian Seibold
Despite considerable progress in the ability to measure the complex 3-D structure of forests with the improvement of remote-sensing techniques, our mechanistic understanding of how biodiversity is linked to canopy structure is still limited. Here we tested whether the increase in arthropod abundance and richness in beech forest canopies with increasing canopy complexity supports the more-individuals hypothesis or the habitat-heterogeneity hypothesis. We used fogging to collect arthropod samples from 80 standardized plots from canopies of...
Data from: Evolutionary processes, dispersal limitation and climatic history shape current diversity patterns of European dragonfliesStefan Pinkert, Klaas-Douwe B. Dijkstra, Dirk Zeuss, Christoph Reudenbach, Roland Brandl & Christian Hof
We investigated the effects of contemporary and historical factors on the spatial variation of European dragonfly diversity. Specifically, we tested to what extent patterns of endemism and phylogenetic diversity of European dragonfly assemblages are structured by (i) phylogenetic conservatism of thermal adaptations and (ii) differences in the ability of post-glacial recolonization by species adapted to running waters (lotic) and still waters (lentic). We investigated patterns of dragonfly diversity using digital distribution maps and a phylogeny...
Data from: Competitor or facilitator? The ambiguous role of alpine grassland for the early establishment of tree seedlings at treelineHannah Loranger, Gerhard Zotz & Maaike Y. Bader
Alpine treelines are expected to move upslope with a warming climate. However, so far treelines have responded inconsistently and future shifts remain difficult to predict since many factors unrelated to temperature, such as biotic interactions, affect responses at the local scale. Especially during the earliest regeneration stages, trees can be strongly influenced by alpine vegetation via both competition and facilitation. We aimed to understand the relative importance of these two types of interaction in different...
