1. Plant functional traits, in particular specific leaf area (SLA), wood density and seed mass, are often good predictors of individual tree growth rates within communities. Individuals and species with high SLA, low wood density and small seeds tend to have faster growth rates. 2. If community-level relationships between traits and growth have general predictive value, then similar relationships should also be observed in analyses that integrate across taxa, biogeographic regions and environments. Such global...

Data from: Configurational landscape heterogeneity shapes functional community composition of grassland butterflies

1. Landscape heterogeneity represents two aspects of landscape simplification: (i) compositional heterogeneity (diversity of habitat types) and (ii) configurational heterogeneity (number, size and arrangement of habitat patches); both with different ecological implications for community composition. 2. We examined how independent gradients of compositional and configurational landscape heterogeneity, at eight spatial scales, shape taxonomic and functional composition of butterfly communities in 91 managed grasslands across Germany. We used landscape metrics that were calculated from functional maps...

Data from: Geographic and temporal dynamics of a global radiation and diversification in the killer whale

Phillip A. Morin, Kim M. Parsons, Frederick I. Archer, María C. Ávila-Arcos, Lance G. Barrett-Lennard, Luciano Dalla Rosa, Sebastián Duchêne, John W. Durban, Graeme M. Ellis, Steven H. Ferguson, John K. Ford, Michael J. Ford, Cristina Gabrilao, M. Thomas P. Gilbert, Kristin Kaschner, Craig O. Matkin, Stephen D. Petersen, Kelly M. Robertson, Ingrid N. Visser, Paul R. Wade, Simon Y. W. Ho & Andrew D. Foote
Global climate change during the Late Pleistocene periodically encroached and then released habitat during the glacial cycles, causing range expansions and contractions in some species. These dynamics have played a major role in geographic radiations, diversification and speciation. We investigate these dynamics in the most widely distributed of marine mammals, the killer whale (Orcinus orca), using a global data set of over 450 samples. This marine top predator inhabits coastal and pelagic ecosystems ranging from...

Data from: Biotic and climatic velocity identify contrasting areas of vulnerability to climate change

Carlos Carroll, Joshua J. Lawler, David R. Roberts & Andreas Hamann
Metrics that synthesize the complex effects of climate change are essential tools for mapping future threats to biodiversity and predicting which species are likely to adapt in place to new climatic conditions, disperse and establish in areas with newly suitable climate, or face the prospect of extirpation. The most commonly used of such metrics is the velocity of climate change, which estimates the speed at which species must migrate over the earth’s surface to maintain...

Data from: Striking cuticular hydrocarbon dimorphism in the mason wasp Odynerus spinipes and its possible evolutionary cause (Hymenoptera: Chrysididae, Vespidae)

Cleptoparasitic wasps and bees smuggle their eggs into the nest of a host organism. Here the larvae of the cleptoparasite feed upon the food provision intended for the offspring of the host. As cleptoparasitism incurs a loss of fitness for the host organism (offspring of the host fail to develop), hosts of cleptoparasites are expected to exploit cues that alert them to potential cleptoparasite infestation. Cuticular hydrocarbons (CHCs) could serve as such cues, as insects...

Data from: Climate impacts on trans-ocean dispersal and habitat in gray whales from the Pleistocene to 2100

Arctic animals face dramatic habitat alteration due to ongoing climate change. Understanding how such species have responded to past glacial cycles can help us forecast their response to today's changing climate. Gray whales are among those marine species likely to be strongly affected by Arctic climate change, but a thorough analysis of past climate impacts on this species has been complicated by lack of information about an extinct population in the Atlantic. While little is...

Data from: Natural habitat does not mediate vertebrate seed predation as an ecosystem dis-service to agriculture

Jessica Schäckermann, Yael Mandelik, Noam Weiss, Henrik Von Wehrden & Alexandra-Maria Klein
1. Spillover of beneficial organisms from natural habitats to croplands can improve agro-ecosystem services, but wildlife can also negatively influence agricultural production. When managing agricultural landscapes to conserve biodiversity, we need to understand if the availability of natural habitats increases ecosystem dis-services such as vertebrate seed predation to avoid risking higher costs than benefits. 2. We studied whether vertebrates and their impact in crop seed predation are related to the percentage of natural (Chaparral) and...

Data from: Effects of management on aquatic tree-hole communities in temperate forests are mediated by detritus amount and water chemistry

Martin M. Gossner, Peggy Lade, Anja Rohland, Nora Sichardt, Tiemo Kahl, Jürgen Bauhus, Wolfgang W. Weisser & Jana S. Petermann
1. Arthropod communities in water-filled tree-holes may be sensitive to impacts of forest management, for example via changes in environmental conditions such as resource input. 2. We hypothesized that increasing forest management intensity negatively affects arthropod abundance and richness and shifts community composition and trophic structure of tree-hole communities. We predicted that this shift is caused by reduced habitat and resource availability at the forest stand scale as well as reduced tree-hole size, detritus amount...

Data from: Gonadotropin-releasing hormone antagonists versus standard androgen suppression therapy for advanced prostate cancer: a systematic review with meta-analysis

Frank Kunath, Hendrik Borgmann, Anette Blümle, Bastian Keck, Bernd Wullich, Christine Schmucker, Danijel Sikic, Catharina Roelle, Schmidt Stefanie, Amr Wahba & Joerg J. Meerpohl
Objectives: To evaluate efficacy and safety of gonadotropin-releasing hormone (GnRH) antagonists compared to standard androgen suppression therapy for advanced prostate cancer. Setting: The international review team included methodologists of the German Cochrane Centre and clinical experts. Participants: We searched CENTRAL, MEDLINE, Web of Science, EMBASE, trial registries and conference books for randomised controlled trials (RCT) for effectiveness data analysis, and randomised or non-randomised controlled studies (non-RCT) for safety data analysis (March 2015). Two authors independently...
