Transcriptional response of mushrooms to artificial sun exposure

Franz-Sebastian Krah, Jaqueline Hess, Florian Hennicke, Ritwika Kar & Claus Bässler
Climate change causes increased tree mortality leading to canopy loss and thus sun-exposed forest floors. Sun exposure creates extreme temperatures and radiation, with potentially more drastic effects on forest organisms than the current increase in mean temperature. Such conditions might potentially negatively affect the maturation of mushrooms of forest fungi. A failure of reaching maturation would mean no sexual spore release and, thus, entail a loss of genetic diversity. However, we currently have a limited...

Plant history and soil history jointly influence the selection environment for plant species in a long-term grassland biodiversity experiment

Peter Dietrich, Nico Eisenhauer, Peter Otto & Christiane Roscher
Long-term biodiversity experiments have shown increasing strengths of biodiversity effects on plant productivity over time. However, little is known about rapid evolutionary processes in response to plant community diversity, which could contribute to explaining the strengthening positive relationship. To address this issue, we performed a transplant experiment with offspring of seeds collected from four grass species in a 14-year old biodiversity experiment (Jena Experiment). We used two- and six-species communities and removed the vegetation of...

Fire alters diversity, composition and structure of dry tropical forests in the Eastern Ghats

Neeraja U. V., Rajendrakumar S., Saneesh C. S., Venkat Dyda & Tiffany M. Knight
Fire is known to have dramatic consequences on forest ecosystems around the world, and on the livelihoods of forest-dependent people. While the Eastern Ghats of India have high abundances of fire-prone dry tropical forests, little is known about how fire influences the diversity, composition and structure of these communities. Our study aims to fill this knowledge gap by examining the effects of presence and absence of recent fire on tropical dry forest communities within Kadiri...

Agriculture causes homogenization of plant-feeding nematode communities at the regional scale

Antonio Archidona-Yuste, Thorsten Wiegand, Nico Eisenhauer, Carolina Cantalapiedra-Navarrete, Juan E. Palomares-Rius & Pablo Castillo
1. An emerging research line in conservation ecology addresses how environmental change drivers may cause the biotic homogenization of ecological communities by shifts in species diversity and community composition. While the drivers have been explored in unmanaged ecosystems and managed agricultural systems, this issue has received limited attention in regards to a key soil bioindicator organisms, soil nematodes. 2. In this study, we evaluated the effect of land-use change and intensification on the diversity of...

Effects of different types of low-intensity management on plant-pollinator interactions in Estonian grasslands

Elena Motivans Švara
In the face of global pollinator decline, extensively-managed grasslands play an important role in supporting stable pollinator communities. However, different types of extensive management may promote particular plant species and thus particular functional traits. As the functional traits of flowering plant species (e.g. flower size and shape) in a habitat determine the identity and frequency of pollinator visitors, they can also influence the structures of plant-pollinator interaction networks. The aim of this study was to...

ddRAD-derived genotypes of Centaurea jacea and Betonica officinalis populations from the White Carpathians

Johannes Höfner, Theresa Klein-Raufhake, Christian Lampei, Ondrej Mudrak, Anna Bucharova & Walter Durka
Ecological restoration and plant re-introductions aim to create plant populations that are genetically similar to natural populations to preserve the regional gene pool, yet genetically diverse to allow adaptation to a changing environment. For this purpose, seeds for restoration are increasingly sourced from multiple populations in the target region. However, it has only rarely been tested whether using regional seed indeed leads to genetically diverse restored populations which are genetically similar to natural populations. We...

Detection dogs in nature conservation: a database on their worldwide deployment with a review on breeds used and their performance compared to other methods

Annegret Grimm-Seyfarth, Wiebke Harms & Anne Berger
Over the last century, dogs have been increasingly used to detect rare and elusive species or traces of them. The use of wildlife detection dogs (WDD) is particularly well established in North America, Europe and Oceania, and projects deploying them have increased worldwide. However, if they are to make a significant contribution to conservation and management, their strengths, abilities, and limitations should be fully identified. We reviewed the use of WDD with particular focus on...

Data from: Landscape heterogeneity filters functional traits of rice arthropods in tropical agroecosystems

Christophe Dominik, Ralf Seppelt, Finbarr G. Horgan, Josef Settele & Tomáš Václavík
Biological control services of agroecosystems depend on the functional diversity of species traits. However, the relationship between arthropod traits and landscape heterogeneity is still poorly understood, especially in tropical rice agroecosystems which harbour a high diversity of often specialized species. We investigated how landscape heterogeneity, measured by three metrics of landscape composition and configuration, influenced body size, functional group composition, dispersal ability and vertical distribution of rice-arthropods in the Philippines. We found that landscape composition...

Biodiversity facets, canopy structure and surface temperature of grassland communities

Claudia Regina Guimaraes-Steinicke, Alexandra Weigelt, Raphaël Prouxl, Thomas Lanners, Nico Eisenhauer, Joaquín Duque-Lazo, Björn Reu, Christiane Roscher, Cameron Wagg, Nina Buchmann & Christian Wirth
Canopy structure is an important driver of the energy budget of the grassland ecosystem and is, at the same time, altered by plant diversity. Diverse plant communities typically have taller and more densely packed canopies than less diverse communities. With this, they absorb more radiation, have a higher transpiring leaf surface, and are better coupled to the atmosphere which leads to cooler canopy surfaces. However, whether plant diversity generally translates into a cooling potential remains...

Data from: Tree species rather than type of mycorrhizal association drives inorganic and organic nitrogen acquisition in tree-tree interactions

Judy Simon, Robert Reuter, Olga Ferlian, Mika Tarkka, Nico Eisenhauer & Karin Pritsch
A field study was conducted to evaluate the effects of associated mycorrhization type on tree-tree interactions using the framework of the MyDiv tree diversity experiment established at the Bad Lauchstädt Experimental Research Station of the Helmholtz Centre for Environmental Research (UFZ) (Saxony-Anhalt, Germany). Inorganic and organic net N uptake capacity was quantified in fine roots of AM (i.e. Acer pseudoplatanus L., Fraxinus excelsior L., and Prunus avium L.) as well as EM associated tree species...

Data from: Plant diversity effects on plant longevity and their relationships to population stability in experimental grasslands

Anna Roeder & Christiane Roscher
In a 12-year old biodiversity experiment (Jena Experiment) comprising 80 grassland communities with six levels of plant species richness (1, 2, 4, 8, 16 and 60 species) and four levels of functional groups richness (1, 2, 3 and 4 functional groups), we studied populations of 38 dicotyledonous forb species (N = 1,683 plant individuals). The sampled individuals represented three plant functional groups (legumes, small herbs, tall herbs) and two different growth forms (species with long-lived...

Reduced host-plant specialization is associated with the rapid range expansion of a Mediterranean butterfly

Anika Neu, Stefan Lötters, Linda Nörenberg, Martin Wiemers & Klaus Fischer
Aim: Species ranges are highly dynamic, shifting in space and time as a result of complex ecological and evolutionary processes. Disentangling the relative contribution of both processes is challenging but of primary importance for forecasting species distributions under climate change. Here, we use the spectacular range expansion (ca. 1,000 km poleward shift within 10 years) of the butterfly Pieris mannii to unravel the factors underlying range dynamics, specifically the role of (i) niche evolution (changes...

Screening of 6000 compounds for uncoupling activity: input parameters, the predicted uncoupling activity, as well as the results in respect to structural alerts

Andrea Ebert
Protonophoric uncoupling of phosphorylation is an important factor when assessing chemicals for their toxicity, and has recently moved into focus in pharmaceutical research with respect to the treatment of diseases such as cancer, diabetes or obesity. Reliably identifying uncoupling activity is thus a valuable goal. To that end, we screened more than 6000 anionic compounds for in-vitro uncoupling activity, using a biophysical model based on ab-initio COSMO-RS input parameters with the molecular structure as the...

Opposing community assembly patterns for dominant and non-dominant plant species in herbaceous ecosystems globally

Carlos Alberto Arnillas, Elizabeth Borer, Eric Seabloom, Juan Alberti, Selene Baez, Jonathon Bakker, Elizabeth Boughton, Yvonne Buckley, Miguel Bugalho, Ian Donohue, John Dwyer, Jennifer Firn, Riley Gridzak, Nicole Hagenah, Yann Hautier, Aveliina Helm, Anke Jentsch, , Kimberly Komatsu, Lauri Laanisto, Ramesh Laungani, Rebecca McCulley, Joslin Moore, John Morgan, Pablo Peri … & Marc Cadotte
Biotic and abiotic factors interact with dominant plants —the locally most frequent or with the largest coverage— and non-dominant plants differently, partially because dominant plants modify the environment where non-dominant plants grow. For instance, if dominant plants compete strongly, they will deplete most resources, forcing non-dominant plants into a narrower niche space. Conversely, if dominant plants are constrained by the environment, they might not exhaust available resources but instead may ameliorate environmental stressors that usually...

Aim: Recent studies suggest insect declines in parts of Europe; however, the generality of these trends across different taxa and regions remains unclear. Standardized data are not available to assess large-scale, long-term changes for most insect groups but opportunistic citizen science data is widespread for some. Here, we took advantage of citizen science data to investigate distributional changes of Odonata. Location: Germany Methods: We compiled over 1 million occurrence records from different regional databases. We...
