Negative relationships between species richness and elevation are common and attributed to changes in single environmental properties associated to elevation, such as temperature and habitat area. However, research has lacked taxonomic breadth and comprehensive elevation studies that consider multiple groups from different trophic levels are rare. We thus analysed 24 groups of plants, arthropods, and microorganisms grouped into six trophic guilds (predators, detritivores, herbivores, plants, bacteria and fungi) along a relatively short elevational gradient (~600...
1. Reductions in community evenness can lead to local extinctions as dominant species exclude subordinate species; however, herbivores can prevent competitive exclusion by consuming otherwise dominant plant species, thus increasing evenness. While these predictions logically result from chronic, gradual reductions in evenness, rapid, temporary pulses of dominance may also reduce species richness. Short pulses of dominance can occur as biotic or abiotic conditions temporarily favor one or a few species, manifested as increased temporal variability...
Data from: Biodiversity change is uncoupled from species richness trends: consequences for conservation and monitoringHelmut Hillebrand, Bernd Blasius, Elizabeth T. Borer, Jonathan M. Chase, John Downing, Britas Klemens Eriksson, Christopher T. Filstrup, W. Stanley Harpole, Dorothee Hodapp, Stefano Larsen, Aleksandra M. Lewandowska, Eric W. Seabloom, Dedmer B.

1. Global concern about human impact on biological diversity has triggered an intense research agenda on drivers and consequences of biodiversity change in parallel with international policy seeking to conserve biodiversity and associated ecosystem functions. Quantifying the trends in biodiversity is far from trivial, however, as recently documented by meta-analyses which report little if any net change of local species richness through time. 2. Here, we summarize several limitations of species richness as a metric...
Data from: Role of multiple invasion mechanisms and their interaction in regulating the population dynamics of an exotic treeRaelene M. Crandall & Tiffany M. Knight
Understanding the mechanisms that allow exotic species to have rapid population growth is an important step in the process of controlling existing invasions and preventing future invasions. Several hypotheses have been proposed to explain why some exotic species become invasive, the most prominent of which focus on the roles of habitat disturbance, competitors and consumers. The magnitude and direction of each of these mechanisms on population dynamics observed in previous studies is quite variable. It...
Carbon and nitrogen flux, meteorological, management and soil data from a grazed, cut and fertilised temperate grassland in south east ScotlandS.K. Jones, C. Helfter, M. Anderson, M. Coyle, C. Campbell, D. Famulari, C. Di Marco, N. Van Dijk, Y.S. Tang, C.F.E. Topp, R. Kiese, R. Kindler, J. Siemens, M. Schrumpf, K. Kaiser, E. Nemitz, P.E. Levy, R.M. Rees, M.A. Sutton & U.M. Skiba
This dataset contains measured daily values of precipitation, air and soil temperature, soil water content, measured net ecosystem exchange (NEE) fluxes using eddy covariance, calculated gross primary production (GPP), terrestrial ecosystem respiration (TER) and net biome production (NBP) fluxes using an online tool (http://www.bgc-jena.mpg.de/~MDIwork/eddyproc/upload.php), measured fluxes of methane and nitrous oxide using static chambers and measured fluxes of nitrous oxide using eddy covariance, measured fluxes of nitrogen oxides (NOx) using automatic chambers, measured nitrogen and...
Data from: Characterization of unexplored deadwood mycobiome in highly diverse subtropical forests using culture-independent molecular techniqueWitoon Purahong, Katherina A. Pietsch, Guillaume Lentendu, Ricardo Schöps, Helge Bruelheide, Christian Wirth, François Buscot & Tesfaye Wubet
The deadwood mycobiome, also known as wood-inhabiting fungi (WIF), are among the key players in wood decomposition, having a large impact on nutrient cycling in forest soils. However, our knowledge of WIF richness and distribution patterns in different forest biomes is limited. Here, we used pyrotag sequencing of the fungal internal transcribed spacer (ITS2) region to characterize the deadwood mycobiome of two tree species with greatly different wood characteristics (Schima superba and Pinus massoniana) in...
