Data from: Below-ground resource partitioning alone cannot explain the biodiversity–ecosystem function relationship: a field test using multiple tracers

Annette Jesch, Kathryn E. Barry, Janneke M. Ravenek, Dörte Bachmann, Tanja Strecker, Alexandra Weigelt, Nina Buchmann, Hans De Kroon, Arthur Gessler, Liesje Mommer, Christiane Roscher & Michael Scherer-Lorenzen
1. Belowground resource partitioning is among the most prominent hypotheses for driving the positive biodiversity-ecosystem function relationship. However, experimental tests of this hypothesis in biodiversity experiments are scarce, and the available evidence is not consistent. 2. We tested the hypothesis that resource partitioning in space, in time, or in both space and time combined drives the positive effect of diversity on both plant productivity and community resource uptake. At the community level, we predicted that...

Data from: Comparing the sampling performance of sound recorders versus point counts in bird surveys: a meta-analysis

Kevin Darras, Péter Batáry, Brett Furnas, Antonio Celis-Murillo, Steven L. Van Wilgenburg, Yeni Ariyati Mulyani & Teja Tscharntke
1) Autonomous sound recording is a promising survey method for birds and other vocalising terrestrial wildlife. However, while there are clear advantages of sound recording methods over classical point counts conducted by humans, it has been difficult to quantitatively assess how they compare in their sampling performance. Quantitative comparisons of bird species richness between acoustic recorders and human point counts have previously been hampered by the differing and often unknown detection ranges among sampling methods....

Data from: Tropical rainforest conversion and land-use intensification reduce understory plant phylogenetic diversity

Yayan Wahyu Candra Kusuma, Katja Rembold, Sri S. Tjitrosoedirdjo & Holger Kreft
1. Conversion of rainforest into agricultural land affects multiple facets of tropical plant diversity. While the effects of tropical land use change and intensification on species diversity are comparatively well studied, the effects on phylogenetic diversity and structure of plant communities are largely unknown. Furthermore, it is not clear how the loss of native species and addition of alien species collectively affect phylogenetic diversity and structure. 2. We investigated the phylogenetic diversity and structure of...

Data from: Globally consistent impact of tropical cyclones on the structure of tropical and subtropical forests

Thomas Ibanez, Gunnar Keppel, Christophe Menkes, Thomas W. Gillespie, Matthieu Lengaigne, Morgan Mangeas, Gonzalo Rivas-Torres & Philippe Birnbaum
1. Tropical cyclones (TCs) are large-scale disturbances that regularly impact tropical forests. Although long-term impacts of TCs on forest structure have been proposed, a global test of the relationship between forest structure and TC frequency and intensity is lacking. We test on a pantropical scale whether TCs shape the structure of tropical and subtropical forests in the long-term. 2. We compiled forest structural features (stem density, basal area, mean canopy height and maximum tree size)...

Data from: Facultative bacterial endosymbionts shape parasitoid food webs in natural host populations: a correlative analysis

Zhengpei Ye, Ines M. G. Vollhardt, Nadia Parth, Oskar Rubbmark & Michael Traugott
1.Facultative bacterial endosymbionts can protect their aphid hosts from natural enemies such as hymenopteran parasitoids. As such, they have the capability to modulate interactions between aphids, parasitoids and hyperparasitoids. However, the magnitude of these effects in natural aphid populations and their associated parasitoid communities is currently unknown. Moreover, environmental factors such as plant fertilization and landscape complexity are known to affect aphid‐parasitoid interactions but it remains unclear how such environmental factors affect the interplay between...

Data from: Phenotypic responses to microbial volatiles render a mold fungus more susceptible to insect damage

Silvia Caballero Ortiz, Monika Trienens, Katharina Pfohl, Petr Karlovsky, Gerrit Holighaus & Marko Rohlfs
In decomposer systems, fungi show diverse phenotypic responses to volatile organic compounds of microbial origin (volatiles). The mechanisms underlying such responses and their consequences for the performance and ecological success of fungi in a multitrophic community context have rarely been tested explicitly. We used a laboratory‐based approach in which we investigated a tripartite yeast–mold–insect model decomposer system to understand the possible influence of yeast‐borne volatiles on the ability of a chemically defended mold fungus to...

Data from: Assessing the relationship between illegal hunting of ungulates, wild prey occurrence and livestock depredation rate by large carnivores

Mahmood Soofi, Arash Ghoddousi, Thorsten Zeppenfeld, Shirko Shokri, Mobin Soufi, Lukas Egli, Abbas Jafari, Mohsen Ahmadpour, Ali Qashqaei, Taher Ghadirian, Marc Filla, Bahram Kiabi, Niko Balkenhol, Matthias Waltert & Igor Khorozyan
1. Illegal hunting of ungulates can reduce the prey base of carnivores, which can increase human-carnivore conflict (HCC) through livestock depredation. However, the relationship between ungulate poaching, wild prey abundance and livestock depredation has rarely been empirically studied. 2. We surveyed 18 sites across the Hyrcanian forest in northern Iran; a global biodiversity hotspot under pressure of illegal hunting of ungulates, prey depletion, livestock grazing and HCC. We conducted three field surveys across 1204 km...

Data from: Validation and utilization of amended diagnostic criteria in Creutzfeldt-Jakob Disease surveillance

Peter Hermann, Mareike Laux, Markus Glatzel, Jakob Matschke, Tobias Knipper, Stefan Goebel, Johannes Treig, Walter Schulz-Schaeffer, Maria Cramm, Matthias Schmitz & Inga Zerr
Objective: To validate an amended protocol for clinical diagnosis of sporadic Creutzfeldt-Jakob Disease (sCJD) including Real-Time Quaking-induced Conversion (RT-QuIC) and to observe its utilization in CJD surveillance. Methods: In the framework of a prospective epidemiological study, all neuropathological confirmed sCJD cases that received CSF RT-QuIC analysis during diagnostic work up (n=65) and a control group of non- CJD cases (n=118) were selected to investigate the accuracy of an amended diagnostic protocol. The patients had been...
