Data on epiphytic lichens along elevational gradients in South Tyrol, Italy

Juri Nascimbene, Hugo Saiz, Alessandro Chiarucci & Matteo Dainese
1. Several studies have evaluated lichen responses in terms of shifts in species climate suitability, species richness, and community composition. In contrast, patterns of co-occurrence among species that could be related to complex species interactions have received less consideration. Biotic interactions play a major role in shaping species niches, fitness, and adaptation to new environments. Therefore, considering the specific relationships among co-occurring species is essential to further deepen our knowledge of biodiversity response to climate...

The plot thickens: Haploid and triploid-like thalli, hybridization, and biased mating type ratios in Letharia

The study of the reproductive biology of lichen fungal symbionts has been traditionally challenging due to their complex and symbiotic lifestyles. Against the common belief of haploidy, a recent genomic study found a triploid-like signal in Letharia. Here, we used genomic data from a pure culture and from thalli, together with a PCR survey of the MAT locus, to infer the genome organization and reproduction in Letharia. We found that the read count variation in...

Data from: All is fish that comes to the net: metabarcoding for rapid fisheries catch assessment

AbstractMonitoring marine resource exploitation is a key activity in fisheries science and biodiversity conservation. Since research surveys are time-consuming and costly, fishery-dependent data (i.e. derived directly from fishing vessels) are increasingly credited with a key role in expanding the reach of ocean monitoring. Fishing vessels may be seen as widely ranging data-collecting platforms, which could act as a fleet of sentinels for monitoring marine life, in particular exploited stocks. Here, we investigate the possibility of...

Gene expression data of Sinorhizobium meliloti-alfalfa initiation of symbiosis

Rhizobia are ecologically important, facultative plant symbiotic microbes. In nature there exists large variability in the association of rhizobial strains and host plants of the same species. Here, we evaluated whether plant and rhizobial genotypes influence the initial transcriptional response of rhizobium following perception of host plant. RNA-sequencing of the model rhizobium Sinorhizobium meliloti exposed to root exudates or luteolin was performed in a combination of three S. meliloti strains and three Medicago sativa varieties....

Data from: Competition among native and invasive Phragmites australis populations: an experimental test of the effects of invasion status, genome size, and ploidy level.

Among the traits whose relevance for plant invasions has recently been suggested are genome size (the amount of nuclear DNA) and ploidy level. So far, research on the role of genome size in invasiveness has been mostly based on indirect evidence by comparing species with different genome sizes, but how karyological traits influence competition at the intraspecific level remains unknown. We addressed these questions in a common‐garden experiment evaluating the outcome of direct intraspecific competition...

Zonazione sismogenetica ZS9

Carlo Meletti, Fabrizio Galadini, Gianluca Valensise, Massimiliano Stucchi, Roberto Basili, Salvatore Barba, Gianfranco Vannucci & Enzo Boschi
ZS9 is a seismic source model for Italy to be used as an input for country-wide probabilistic seismic hazard assessment (PSHA) in the frame of the compilation of the national reference map. ZS9 is made out of 36 zones where earthquakes with Mw > = 5 are expected. It also assumes that earthquakes with Mw up to 5 may occur anywhere outside the seismogenic zones, although the associated probability is rather low. Special care was...

Intraspecific variation of Phragmites australis: Clinal adaption of functional traits and phenotypic plasticity vary with latitude of origin

Linjing Ren, Xiao Guo, Shuna Liu, Ting Yu, Weihua Guo, Renqing Wang, Siyuan Ye, Carla Lambertini, Hans Brix & Franziska Eller
1. Widespread plant species generally have high intraspecific variation in functional traits, which is reflected in their great variety of phenotypes. This variety can result from both genetic differences due to local adaptation and phenotypic plasticity. With high intraspecific variation and nearly global distribution, the common reed Phragmites australis is a suitable model species for studying the underlying mechanisms of intraspecific trait variation. 2. In this study, 71 genotypes of P. australis from seven phylogeographic...

Data from: Diverse communities of bacteria and archaea flourished in Palaeoarchaean (3.5-3.3 Ga) microbial mats

Keyron Hickman-Lewis, Frances Westall & Barbara Cavalazzi
Limited taxonomic classification is possible for Archaean microbial mats and this is a fundamental limitation in constraining early ecosystems. Applying Fourier Transform Infrared spectroscopy (FTIR), a powerful tool for identifying vibrational motions attributable to specific functional groups, we characterised fossilised biopolymers in 3.5-3.3 Ga microbial mats from the Barberton greenstone belt (South Africa). Microbial mats from four Palaeoarchaean horizons exhibit significant differences in taxonomically informative aliphatic contents, despite high aromaticity. This reflects precursor biological heterogeneity...

Data and R code for: An experimental approach to assessing the impact of ecosystem engineers on biodiversity and ecosystem functions

Gianalberto Losapio, Bernhard Schmid, Jordi Bascompte, Richard Michalet, Pierfilippo Cerretti, Christoph Germann, Jean-Paul Haenni, Rainer Neumeyer, Francisco Javier Ortiz-Sánchez, Adrian C Pont, Pascal Rousse, Jürg Schmid, Daniele Sommaggio & Christian Schöb
Plants acting as ecosystem engineers create habitats and facilitate biodiversity maintenance within plant communities. Furthermore, biodiversity research has demonstrated that plant diversity enhances the productivity and functioning of ecosystems. However, these two fields of research developed in parallel and independent from one another, with the consequence that little is known about the role of ecosystem engineers in the relationship between biodiversity and ecosystem functioning across trophic levels. Here, we present an experimental framework to study...
