Data from: Climate outweighs native vs. non-native range-effects for genetics and common garden performance of a cosmopolitan weed

Christoph Rosche, Isabell Hensen, Adrian Schaar, Uzma Zehra, Marie Jasieniuk, Ragan M. Callaway, Damase P. Khasa, Mohammad M. Al-Gharaibeh, Ylva Lekberg, David U. Nagy, Robert W. Pal, Miki Okada, Karin Schrieber, Kathryn G. Turner, Susanne Lachmuth, Andrey Erst, Tomonori Tsunoda, Min Sheng, Robin Schmidt, Yanling Peng, Wenbo Luo, Yun Jäschke, Zafar A. Reshi & Manzoor A. Shah
Comparing genetic diversity, genetic differentiation and performance between native and non-native populations has advanced our knowledge of contemporary evolution and its ecological consequences. However, such between-range comparisons can be complicated by high among-population variation within native and non-native ranges. For example, native vs. non-native comparisons between small and non-representative subsets of populations for species with very large distributions have the potential to mislead because they may not sufficiently account for within-range adaptation to climatic conditions,...

Data from: Exploratory and confirmatory research in the open science era

Erlend B. Nilsen, Diana Bowler & John Linnell
1. Applied ecological research is increasingly inspired by the Open Science movement. However, new challenges about how we define our science when biodiversity data is being shared and re-used are not solved. Among these challenges is the risk associated with blurring the distinction between research that mainly seeks to explore patterns with no a-priori articulated hypotheses (exploratory research), and research that explicitly tests a-priori formulated hypotheses (confirmatory research). 2. A rapid screening of a random...

Ecological traps and species distribution models: a challenge for prioritizing areas of conservation importance

Nicolas Titeux, Olatz Aizpurua, Franck Hollander, Francesc Sardà-Palomera, Virgilio Hermoso, Jean-Yves Paquet, Xavier Mestdagh, Josef Settele, Lluís Brotons & Hans Van Dyck
Species distribution models analyse how species use different types of habitats. Their spatial predictions are often used to prioritize areas for conservation. Individuals may, however, prefer settling in habitat types of low quality compared to other available habitats. This ecological trap phenomenon is usually studied in a small number of habitat patches and consequences at the landscape level are largely unknown. It is therefore often unclear whether the spatial pattern of habitat use is aligned...

Data from Soil chemistry turned upside down: a meta-analysis of invasive earthworm effects on soil chemical properties

Olga Ferlian, Madhav P. Thakur, Alejandra Castañeda González, Layla M. San Emeterio, Susanne Marr, Barbbara Da Silva Rocha & Nico Eisenhauer
Recent studies have shown that invasive earthworms can dramatically reduce native biodiversity, both above and below the ground. However, we still lack a synthetic understanding of the underlying mechanisms behind these changes, such as whether earthworm effects on soil chemical properties drive such relationships. Here, we investigated the effects of invasive earthworms on soil chemical properties (pH, water content, and the stocks and fluxes of carbon, nitrogen, and phosphorus) by conducting a meta-analysis. Invasive earthworms...

Data from: Parasitoid wasps indirectly suppress seed production by stimulating consumption rates of their seed-feeding hosts

Xinqiang Xi, Nico Eisenhauer & Sun Shucun
1. In parasitoid–herbivore–plant food chains, parasitoids may be simultaneously linked with both herbivore hosts and plants, as occurs when herbivores attacked by parasitoids continue to consume plants although they are destined to die. This peculiar property may cause parasitoids to confer a differential trophic cascading effect on plants than that known for typical predators. 2. We hypothesized that larval koinobiont parasitoids would confer an immediate negative effect on plant seed production by stimulating consumption of...

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: 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: Species richness change across spatial scales

Jonathan M. Chase, Brian J. McGill, Patrick L. Thompson, Laura H. Antão, Amanda E. Bates, Shane A. Blowes, Maria Dornelas, Andrew Gonzalez, Anne E. Magurran, Sarah R. Supp, Marten Winter, Anne D. Bjorkmann, Helge Bruelheide, Jarrett E.K. Byrnes, Juliano Sarmento Cabral, Robin Ehali, Catalina Gomez, Hector M. Guzman, Forest Isbell, Isla H. Myers-Smith, Holly P. Jones, Jessica Hines, Mark Vellend, Conor Waldock & Mary O'Connor
Humans have elevated global extinction rates and thus lowered global-scale species richness. However, there is no a priori reason to expect that losses of global species richness should always, or even often, trickle down to losses of species richness at regional and local scales, even though this relationship is often assumed. Here, we show that scale can modulate our estimates of species richness change through time in the face of anthropogenic pressures, but not in...

Data from: Soil drainage facilitates earthworm invasion and subsequent carbon loss from peatland soil

Xinwei Wu, Rui Cao, Xue Wei, Xinqiang Xi, Peili Shi, Nico Eisenhauer & Shucun Sun
1. Human activities have been a significant driver of environmental changes with tremendous consequences for carbon dynamics. Peatlands are critical ecosystems because they store ~30% of the global soil organic carbon pool and are particularly vulnerable to anthropogenic changes. The Zoige peatland on the eastern Tibet Plateau, as the largest alpine peatland in the world, accounts for 1‰ of global peat soil organic carbon storage. However, this peatland has experienced dramatic climate change including increased...

Data from: High specialization and limited structural change in plant‐herbivore networks along a successional chronosequence in tropical montane forest

Conor M. Redmond, John Auga, Bradley Gewa, Simon T. Segar, Scott E. Miller, Kenneth Molem, George D. Weiblen, Phillip T. Butterill, Gibson Maiyah, Amelia S.C. Hood, Martin Volf, Leonardo R. Jorge, Yves Basset, Vojtech Novotny, Philip T. Butterill & Amelia S. C. Hood
Secondary succession is well‐understood, to the point of being predictable for plant communities, but the successional changes in plant‐herbivore interactions remains poorly explored. This is particularly true for tropical forests, despite the increasing importance of early successional stages in tropical landscapes. Deriving expectations from successional theory, we examine properties of plant‐herbivore interaction networks while accounting for host phylogenetic structure along a succession chronosequence in montane rainforest in Papua New Guinea. We present one of the...

Data from: Cascading spatial and trophic impacts of oak decline on the soil food web

Jara Domínguez-Begines, Gerlinde B. De Deyn, Luis V. Garcia, Nico Eisenhauer & Lorena Gomez-Aparicio
1. Tree defoliation and mortality have considerably increased worldwide during the last decades due to global change drivers such as increasing drought or invasive pests and pathogens. However, the effects of this tree decline on soil food webs are poorly understood. 2. In this study we evaluated the impacts of Quercus suber decline on soil food webs of Mediterranean mixed forests invaded by the exotic oomycete pathogen Phytophthora cinnamomi, using soil nematodes as bioindicator taxa....

Data from: Stronger effect of gastropods than rodents on seedling establishment, irrespective of exotic or native plant species origin

Lotte Korell, Claudia Stein, Isabell Hensen, Helge Bruelheide, Katharine N. Suding & Harald Auge
Experimental evidence about how generalist consumers affect exotic plant invasions is equivocal, but most tests have been limited to few plant species, single herbivore guilds, and single locations. Using a seed-addition experiment, we studied effects of gastropods and rodents on recruitment success of 37 exotic and 37 native plant species affiliated to three different functional groups (i.e. grasses, legumes and non-legume herbs). We replicated our seed addition x herbivore exclusion experiment at multiple grassland sites,...

Data from: Root and shoot glucosinolate allocation patterns follow optimal defence allocation theory

Tomonori Tsunoda, Sebastian Krosse, Nicole Van Dam & Nicole M. Van Dam
1. Optimal defence allocation theory (ODT) is one of the most prominent theoretical frameworks to explain the allocation of defence compounds within plants. It predicts that the most valuable and vulnerable plant organs have the highest levels of chemical defence. The ODT has been well worked out and experimentally tested for shoot defences, but not for root defences. To assess if ODT principles apply similarly to roots and shoots, we examined glucosinolates in aboveground and...

Diversification in evolutionary arenas – assessment and synthesis

Nicolai M. Nürk, H. Peter Linder, Renske E. Onstein, Matthew J. Larcombe, Colin E. Hughes, Laura Piñeiro Fernández, Philipp M. Schlüter, Luis Valente, Carl Beierkuhnlein, Vanessa Cutts, Michael J. Donoghue, Erika J. Edwards, Richard Field, Suzette G.A. Flantua, Steven I. Higgins, Anke Jentsch, Sigrid Liede-Schumann & Michael D. Pirie
Understanding how and why rates of evolutionary diversification vary is a central issue in evolutionary biology, ecology and biogeography. The concept of adaptive radiation has attracted much interest, but is metaphorical and verbal in nature, making it difficult to quantitatively compare different evolutionary lineages or geographic regions. In addition, the causes of evolutionary stasis are relatively neglected. Here we review the central concepts in the evolutionary diversification literature and bring these together by proposing a...

Data from: Temporal scale-dependence of plant-pollinator networks

Benjamin Schwarz, Diego Vázquez, Paul CaraDonna, Tiffany Knight, Gita Benadi, Carsten Dormann, Benoit Gauzens, Elena Motivans, Julian Resasco, Nico Blüthgen, Laura Burkle, Qiang Fang, Christopher Kaiser-Bunbury, Ruben Alarcón, Justin Bain, Natacha Chacoff, Shuang-Quan Huang, Gretchen LeBuhn, Molly MacLeod, Theodora Petanidou, Claus Rasmussen, Michael Simanonok, Amibeth Thompson, Daniel Cariveau, Michael Roswell … & Jochen Fründ
The study of mutualistic interaction networks has led to valuable insights into ecological and evolutionary processes. However, our understanding of network structure may depend upon the temporal scale at which we sample and analyze network data. To date, we lack a comprehensive assessment of the temporal scale-dependence of network structure across a wide range of temporal scales and geographic locations. If network structure is temporally scale-dependent, networks constructed over different temporal scales may provide very...

Data from: Chemical novelty facilitates herbivore resistance and biological invasions in some introduced plant species

Brian Sedio, John Devaney, Jamie Pullen, Geoffrey Parker, S. Joseph Wright & John Parker
Ecological release from herbivory due to chemical novelty is commonly predicted to facilitate biological invasions by plants, but has not been tested on a community scale. We used metabolomics based on mass spectrometry molecular networks to assess the novelty of foliar secondary chemistry of 15 invasive plant species compared to 46 native species at a site in eastern North America. Locally, invasive species were more chemically distinctive than natives. Among the 15 invasive species, the...

Data from: Cascading effects of climate variability on the breeding success of an edge population of an apex predator

Laura Gangoso, Duarte Viana, Adriaan Dokter, Judy Shamoun-Baranes, Jordi Figuerola, Sergio Barbosa & Willem Bouten
1. Large-scale environmental forces can influence biodiversity at different levels of biological organization. Climate, in particular, is often associated to species distributions and diversity gradients. However, its mechanistic link to population dynamics is still poorly understood. 2. Here, we unraveled the full mechanistic path by which a climatic driver, the Atlantic trade winds, determines the viability of a bird population. 3. We monitored the breeding population of Eleonora’s falcons in the Canary Islands for over...

Data from: PalmTraits 1.0, a species-level functional trait database for palms worldwide

W. Daniel Kissling, Henrik Balslev, William J. Baker, John Dransfield, Bastian Göldel, Jun Ying Lim, Renske E. Onstein & Jens-Christian Svenning
Plant traits are critical to plant form and function —including growth, survival and reproduction— and therefore shape fundamental aspects of population and ecosystem dynamics as well as ecosystem services. Here, we present a global species-level compilation of key functional traits for palms (Arecaceae), a plant family with keystone importance in tropical and subtropical ecosystems. We derived measurements of essential functional traits for all (>2500) palm species from key sources such as monographs, books, other scientific...

Palm fruit colours are linked to the broad-scale distribution and diversification of primate colour vision systems

Renske Onstein, Daphne Vink, Jorin Veen, Christopher Barratt, Suzette Flantua, Serge Wich & Daniel Kissling
A long-standing hypothesis in ecology and evolution is that trichromatic colour vision (the ability to distinguish red from green) in frugivorous primates has evolved as an adaptation to detect conspicuous (reddish) fruits. This could provide a competitive advantage over dichromatic frugivores which cannot distinguish reddish colours from a background of green foliage. Here, we test whether the origin, distribution and diversity of trichromatic primates is positively associated with the availability of conspicuous palm fruits, i.e....

Data from: Temperature and consumer type dependencies of energy flows in natural communities

Birgit Lang, Roswitha B. Ehnes, Ulrich Brose & Björn C. Rall
With the world continuously warming, a mechanistic understanding of how temperature affects interaction strengths, which are fundamental to food-web stability, is needed. As interaction strengths are determined by the flows of energy from resources to consumers, we investigated effects of temperature on animal energetics. We used newly compiled datasets on respiration rates and assimilation efficiencies to assess how temperature affects the energy use (respiration rates) and the efficiency of energy gain (assimilation efficiency) for different...

Data from: GlobTherm, a global database on thermal tolerances for aquatic and terrestrial organisms

Joanne M. Bennett, Piero Calosi, Susana Clusella-Trullas, Brezo Martínez, Jennifer Sunday, Adam C. Algar, Miguel B. Araújo, Bradford A. Hawkins, Sally Keith, Ingolf Kühn, Carsten Rahbek, Laura Rodríguez, Alexander Singer, Fabricio Villalobos, Miguel Ángel Olalla-Tárraga & Ignacio Morales-Castilla
How climate affects species distributions is a longstanding question receiving renewed interest owing to the need to predict the impacts of global warming on biodiversity. Is climate change forcing species to live near their critical thermal limits? Are these limits likely to change through natural selection? These and other important questions can be addressed with models relating geographical distributions of species with climate data, but inferences made with these models are highly contingent on non-climatic...

Data from: Testing the validity of functional response models using molecular gut content analysis for prey choice in soil predators

Bernhard Eitzinger, Björn Rall, Michael Traugott & Stefan Scheu
Analysis of predator - prey interactions is a core concept of animal ecology, explaining structure and dynamics of animal food webs. Measuring the functional response, i.e. the intake rate of a consumer as a function of prey density, is a powerful method to predict the strength of trophic links and assess motives of prey choice, particularly in arthropod communities. However, due to their reductionist set-up, functional responses, which are based on laboratory feeding experiments, may...

Data from: Inter- and intraspecific variation in leaf economics traits in wheat and maize

Adam R. Martin, Christine E. Hale, Bruno E. L. Cerabolini, Johannes H. C. Cornelissen, Joseph Craine, William A. Gough, Jens Kattge & Cairan K. F. Tirona
Leaf economics spectrum (LES) trait variation underpins multiple agroecological processes and many prominent crop yield models. While there are numerous independent studies assessing trait variation in crops, to date there have been no comprehensive assessments of intraspecific trait variation (ITV) in LES traits for wheat and maize: the world’s most widespread crops. Using trait databases and peer-reviewed literature, we compiled over 700 records of specific leaf area (SLA), maximum photosynthetic rates (Amax), and leaf nitrogen...
