Data from: Effects of experimental warming on biodiversity depend on ecosystem type and local species compositionDaniel S. Gruner, Matthew E. S. Bracken, Stella A. Berger, Britas Klemens Eriksson, Lars Gamfeldt, Birte Matthiessen, Stefanie Moorthi, Ulrich Sommer & Helmut Hillebrand
Climatic warming is a primary driver of change in ecosystems worldwide. Here, we synthesize responses of species richness and evenness from 187 experimental warming studies in a quantitative meta-analysis. We asked 1) whether effects of warming on diversity were detectable and consistent across terrestrial, freshwater and marine ecosystems, 2) if effects on diversity correlated with intensity, duration, and experimental unit size of temperature change manipulations, and 3) whether these experimental effects on diversity interacted with...
Data from: Phylogeographic differentiation versus transcriptomic adaptation to warm temperatures in Zostera marina, a globally important seagrassAlexander Jueterbock, Susanne U. Franssen, Nina Bergmann, Jenny Gu, James A. Coyer, Thorsten B. H. Reusch, Erich Bornberg-Bauer & Jeanine L. Olsen
Populations distributed across a broad thermal cline are instrumental in addressing adaptation to increasing temperatures under global warming. Using a space-for-time substitution design, we tested for parallel adaptation to warm temperatures along two independent thermal clines in Zostera marina, the most widely distributed seagrass in the temperate Northern Hemisphere. A North–South pair of populations was sampled along the European and North American coasts and exposed to a simulated heatwave in a common-garden mesocosm. Transcriptomic responses...

Numerous studies show that increasing species richness leads to higher ecosystem productivity. This effect is often attributed to more efficient portioning of multiple resources in communities with higher numbers of competing species, indicating the role of resource supply and stoichiometry for biodiversity–ecosystem functioning relationships. Here, we merged theory on ecological stoichiometry with a framework of biodiversity–ecosystem functioning to understand how resource use transfers into primary production. We applied a structural equation model to define patterns...
Data from: Population genomics of local adaptation versus speciation in coral reef fishes (Hypoplectrus spp, Serranidae)Sophie Picq, Owen McMillan, Oscar Puebla & W. Owen McMillan
Are the population genomic patterns underlying local adaptation and the early stages of speciation similar? Addressing this question requires a system in which i. local adaptation and the early stages of speciation can be clearly identified and distinguished, ii. the amount of genetic divergence driven by the two processes is similar, and iii. comparisons can be repeated both taxonomically (for local adaptation) and geographically (for speciation). Here, we report just such a situation in the...
Data from: Transcriptome profiling of immune tissues reveals habitat-specific gene expression between lake and river sticklebacksYun Huang, Frederic Chain, Mahesh Panchal, Christophe Eizaguirre, Martin Kalbe, Tobias Lenz, Irene Samonte, Monika Stoll, Erich Bornberg-Bauer, Thorsten B. Reusch, Manfred Milinski & Philine Feulner
The observation of habitat-specific phenotypes suggests the action of natural selection. The three-spined stickleback (Gasterosteus aculeatus) has repeatedly colonized and adapted to diverse freshwater habitats across the northern hemisphere since the last glaciation, while giving rise to recurring phenotypes associated with specific habitats. Parapatric lake and river populations of sticklebacks harbour distinct parasite communities, a factor proposed to contribute to adaptive differentiation between these ecotypes. However, little is known about the transcriptional response to the...
Baker's Law predicts uniparental reproduction will facilitate colonization success in novel habitats. While evidence supports this prediction among colonizing plants and animals, few studies have investigated shifts in reproductive mode in haplo-diplontic species in which both prolonged haploid and diploid stages separate meiosis and fertilization in time and space. Due to this separation, asexual reproduction can yield the dominance of one of the ploidy stages in colonizing populations. We tested for shifts in ploidy and...
When there is no recombination (achiasmy) in one sex, it is in the heterogametic one. This observation is so consistent that it constitutes one of the few patterns in biology that may be regarded as a ‘rule’ and Haldane (Haldane 1922 J. Genet. 12, 101–109. (doi:10.1007/BF02983075)) proposed that it might be driven by selection against recombination in the sex chromosomes. Yet differences in recombination rates between the sexes (heterochiasmy) have also been reported in hermaphroditic...
