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...

Data from: Trait variation in response to varying winter temperatures, diversity patterns and signatures of selection along the latitudinal distribution of the widespread grassland plant Arrhenatherum elatius

Stefan G. Michalski, Andrey V. Malyshev & Juergen Kreyling
Across Europe, genetic diversity can be expected to decline toward the North because of stochastic and selective effects which may imply diminished phenotypic variation and less potential for future genetic adaptations to environmental change. Understanding such latitudinal patterns can aid provenance selection for breeding or assisted migration approaches. In an experiment simulating different winter temperatures, we assessed quantitative trait variation, genetic diversity, and differentiation for natural populations of the grass Arrhenatherum elatius originating from a...

Data from: Transient recovery dynamics of a predator–prey system under press and pulse disturbances

Canan Karakoç, Alexander Singer, Karin Johst, Hauke Harms & Antonis Chatzinotas
Background: Species recovery after disturbances depends on the strength and duration of disturbance, on the species traits and on the biotic interactions with other species. In order to understand these complex relationships, it is essential to understand mechanistically the transient dynamics of interacting species during and after disturbances. We combined microcosm experiments with simulation modelling and studied the transient recovery dynamics of a simple microbial food web under pulse and press disturbances and under different...

Data from: Measuring β‐diversity by remote sensing: a challenge for biodiversity monitoring

Duccio Rocchini, Sandra Luque, Nathalie Pettorelli, Lucy Bastin, Daniel Doktor, Nicolò Faedi, Hannes Feilhauer, Jean-Baptiste Féret, Giles M. Foody, Yoni Gavish, Sergio Godinho, William E. Kunin, Angela Lausch, Pedro J. Leitao, Matteo Marcantonio, Markus Neteler, Carlo Ricotta, Sebastian Schmidtlein, Petteri Vihervaara, Martin Wegmann & Harini Nagendra
Biodiversity includes multiscalar and multitemporal structures and processes, with different levels of functional organization, from genetic to ecosystemic levels. One of the mostly used methods to infer bio- diversity is based on taxonomic approaches and community ecology theories. However, gathering extensive data in the field is difficult due to logistic problems, especially when aiming at modelling biodiversity changes in space and time, which assumes statistically sound sampling schemes. In this context, airborne or satellite remote...

Data from: Characterization of unexplored deadwood mycobiome in highly diverse subtropical forests using culture-independent molecular technique

Witoon 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...

Data from: Neighbourhood effects on plant reproduction: an experimental-analytical framework and its application to the invasive Senecio inaequidens

Susanne Lachmuth, Colette Henrichmann, Juliane Horn, Joern Pagel & Frank M. Schurr
1. Density-dependence is of fundamental importance for population and range dynamics. Density-dependent reproduction of plants arises from competitive and facilitative plant-plant interactions that can be pollination-independent or pollination-mediated. In small and sparse populations, conspecific density-dependence often turns from negative to positive and causes Allee effects. Reproduction may also increase with heterospecific density (community-level Allee effect), but the underlying mechanisms are poorly understood and the consequences for community dynamics can be complex. Allee effects have crucial...

Data from: Too hot to die? The effects of vegetation shading on past, present, and future activity budgets of two diurnal skinks from arid Australia

Annegret Grimm-Seyfarth, Jean-Baptiste Mihoub & Klaus Henle
Behavioral thermoregulation is an important mechanism allowing ectotherms to respond to thermal variations. Its efficiency might become imperative for securing activity budgets under future climate change. For diurnal lizards, thermal microhabitat variability appears to be of high importance, especially in hot deserts where vegetation is highly scattered and sensitive to climatic fluctuations. We investigated the effects of a shading gradient from vegetation on body temperatures and activity timing for two diurnal, terrestrial desert lizards, Ctenotus...

Data from: How do leaf trait values change spatially and temporally with light availability in a grassland diversity experiment?

Dörte Bachmann, Christiane Roscher & Nina Buchmann
Complementarity in light use might increase light exploitation and could be an important mechanism explaining the coexistence of multiple species in plant communities of increasing diversity. We measured vertical light profiles and leaf traits related to light acquisition and light use in 40 mixtures of varying species richness (SR, 2, 4, 8 and 16) and functional group richness (FR, 1-4) in a large grassland biodiversity experiment at five different times during the growing season. Light...

Data from: Role of multiple invasion mechanisms and their interaction in regulating the population dynamics of an exotic tree

Raelene 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...

Data from: Distance-dependent seedling mortality and long-term spacing dynamics in a neotropical forest community

Stephen J. Murphy, Thorsten Wiegand & Liza S. Comita
Negative distance dependence (NDisD), or reduced recruitment near adult conspecifics, is thought to explain the astounding diversity of tropical forests. While many studies show greater mortality at near vs. far distances from adults, these studies do not seek to track changes in the peak seedling curve over time, thus limiting our ability to link NDisD to coexistence. Using census data collected over 12 years from central Panama in conjunction with spatial mark-connection functions, we show...

Data from: Habitat filtering determines the functional niche occupancy of plant communities worldwide

Yuanzhi Li, Bill Shipley, Jodi N. Price, Vinícius De L. Dantas, Riin Tamme, Mark Westoby, Andrew Siefert, Brandon S. Schamp, Marko J. Spasojevic, Vincent Jung, Daniel C. Laughlin, Sarah J. Richardson, Yoann Le Bagousse-Pinguet, Christian Schöb, Antonio Gazol, Honor C. Prentice, Nicolas Gross, Jacob Overton, Marcus V. Cianciaruso, Frédérique Louault, Chiho Kamiyama, Tohru Nakashizuka, Kouki Hikosaka, Takehiro Sasaki, Masatoshi Katabuchi … & Marco A. Batalha
How the patterns of niche occupancy vary from species-poor to species-rich communities is a fundamental question in ecology that has a central bearing on the processes that drive patterns of biodiversity. As species richness increases, habitat filtering should constrain the expansion of total niche volume, while limiting similarity should restrict the degree of niche overlap between species. Here, by explicitly incorporating intraspecific trait variability, we investigate the relationship between functional niche occupancy and species richness...

Data from: Altered breeding biology of the European blackbird under artificial light at night

Anja Russ, Terézia Lučeničová & Reinhard Klenke
Artificial light at night (LAN) has become a stressor of global extent. Previous work has highlighted the high potential of LAN to interfere with annual and diel rhythms of seasonal organisms as well as to affect interactions at the community level. However, our understanding how LAN induced alterations of activity and breeding cycles affect the reproductive outcome and fitness of the birds is still limited. Here, we focus on the effects of night time illumination...

Data from: Continental divide: predicting climate-mediated fragmentation and biodiversity loss in the boreal forest

Dennis L. Murray, Michael J.L. Peers, Yasmine N. Majchrzak, Morgan Wehtje, Catarina Ferreira, Rob S.A. Pickles, Jeffrey R. Row, Daniel H. Thornton, Michael J. L. Peers & Rob S. A. Pickles
Climate change threatens natural landscapes through shifting distribution and abundance of species and attendant change in the structure and function of ecosystems. However, it remains unclear how climate-mediated variation in species' environmental niche space may lead to large-scale fragmentation of species distributions, altered meta-population dynamics and gene flow, and disrupted ecosystem integrity. Such change may be especially relevant when species distributions are restricted either spatially or to a narrow environmental niche, or when environments are...

Data from: The impact of even-aged and uneven-aged forest management on regional biodiversity of multiple taxa in European beech forests

Peter Schall, Martin M. Gossner, Steffi Heinrichs, Markus Fischer, Steffen Boch, Daniel Prati, Kirsten Jung, Vanessa Baumgartner, Stefan Blaser, Stefan Böhm, Francois Buscot, Rolf Daniel, Kezia Goldmann, Kirstin Kaiser, Tiemo Kahl, Markus Lange, Jörg Müller, Jörg Overmann, Swen C. Renner, Ernst-Detlef Schulze, Johannes Sikorski, Marco Tschapka, Manfred Türke, Wolfgang W. Weisser, Bernd Wemheuer … & Kristin Kaiser
For managed temperate forests, conservationists and policymakers favour fine-grained uneven-aged management over more traditional coarse-grained even-aged management, based on the assumption that within-stand habitat heterogeneity enhances biodiversity. There is, however, little empirical evidence to support this assumption. We investigated for the first time how differently grained forest management systems affect the biodiversity of multiple above- and below-ground taxa across spatial scales. We sampled 15 taxa of animals, plants, fungi and bacteria within the largest contiguous...

Data from: A spatially integrated framework for assessing socioecological drivers of carnivore decline

Nicolás Gálvez, Gurutzeta Guillera-Arroita, Freya A. V. St. John, Elke Schüttler, David W. Macdonald & Zoe G. Davies
Habitat loss, fragmentation and degradation are key threats to the long-term persistence of carnivores, which are also susceptible to direct persecution by people. Integrating natural and social science methods to examine how habitat configuration/quality and human–predator relations may interact in space and time to effect carnivore populations within human-dominated landscapes will help prioritise conservation investment and action effectively. We propose a socioecological modelling framework to evaluate drivers of carnivore decline in landscapes where predators and...

Data from: Cross-taxa generalities in the relationship between population abundance and ambient temperatures

Diana E. Bowler, Peter Haase, Christian Hof, Ingrid Kröncke, Léon Baert, Wouter Dekoninck, Sami Domisch, Frederik Hendrickx, Thomas Hickler, Hermann Neumann, Robert B. O'Hara, Anne F. Sell, Moritz Sonnewald, Stefan Stoll, Michael Türkay, Roel Van Klink, Oliver Schweiger, Rikjan Vermeulen & Katrin Boehning-Gaese
Identifying patterns in the effects of temperature on species' population abundances could help develop a general framework for predicting the consequences of climate change across different communities and realms. We used long-term population time series data from terrestrial, freshwater, and marine species communities within central Europe to compare the effects of temperature on abundance across a broad range of taxonomic groups. We asked whether there was an average relationship between temperatures in different seasons and...
