Invasive plant impacts vary widely across introduced ranges. We tested the hypothesis that differences in the eco-evolutionary experience of native communities with the invader correspond with the impacts of invasive species on native vegetation, with impacts increasing with ecological novelty. We compared plant species richness and composition beneath Pinus contorta to that in adjacent vegetation and other P. contorta stands across a network of sites in its native (Canada and USA) and non-native (Argentina, Chile,...

Data from: Context-dependent colonisation of terrestrial habitat 'islands' by a long-distance migrant bird

Robin C. Whytock, Elisa Fuentes-Montemayor, Kevin Watts, Nicholas A. Macgregor, Lefora Williams & Kirsty J. Park
Landscape context can affect how individuals perceive patch quality during colonisation. However, although context-dependent colonisation has been observed in aquatic environments it has rarely been studied in terrestrial environments or at large spatial scales. Here, we assessed how landscape context influenced colonisation rates in a large-scale (c.7000 km2) terrestrial system where colonisers (Willow Warbler Phylloscopus trochilus) are capable of rapid, long-distance movements. Bioacoustic recorders were used to detect first song dates (an indicator of colonisation...

UK Environmental Change Network (ECN) spittle bug data: 1993-2015

S. Rennie, J. Adamson, R. Anderson, C. Andrews, J. Bater, N. Bayfield, K. Beaton, D. Beaumont, S. Benham, V. Bowmaker, C. Britt, R. Brooker, D. Brooks, J. Brunt, G. Common, R. Cooper, S. Corbett, N. Critchley, P. Dennis, J. Dick, B. Dodd, N. Dodd, N. Donovan, J. Easter, M. Flexen … & C. Wood
Spittle Bug data from the UK Environmental Change Network (ECN) terrestrial sites. These data are collected by quadrat sampling at all of ECN's terrestrial sites using a standard protocol . They represent continuous annual records from 1993 to 2015. Spittle Bug adults (Philaenus spumarius) are sampled and separated by sex and by colour morph; it is likely that the proportions of morphs are environmentally determined and will therefore be good indicators of environmental change. Spittle...

Data from: Positive effects of liana cutting on seedlings are reduced during El Niño-induced drought

Michael J. O'Brien, Christopher D. Philipson, Glen Reynolds, Dzaeman Dzulkifli, Jake L. Snaddon, Robert Ong & Andy Hector
1. Liana cutting is a management practice currently applied to encourage seedling regeneration and tree growth in some logged tropical forests. However, there is limited empirical evidence of its effects on forest demographic rates in Southeast Asia. 2. We used 22 four-hectare plots in the Sabah Biodiversity Experiment (a reduced impact logging site) enrichment line planted with 16 dipterocarp species to assess the effects of complete liana cutting on tree growth and survival. We compared...

Data from: A versatile method for assessing pathogenicity of Hymenoscyphus fraxineus to ash foliage

Elizabeth S. Orton, Martha Clarke, Clive M. Brasier, Joan F. Webber & James K. M. Brown
We describe a method for inoculating rachises of Fraxinus excelsior (European or common ash) with Hymenoscyphus fraxineus, which is faster than previous methods and allows associated foliar symptoms to be assessed on replicate leaves. A total of ten ash seedlings were inoculated with five isolates of H. fraxineus and lesion development assessed over four weeks. A five‐point disease progress scale of symptom development was developed from no lesion (0), lesion on rachis (1), “pre‐top dead,”...

Data from: Positive biodiversity-productivity relationships in forests: climate matters

Herve Jactel, Emmanuel S. Gritti, Lars Drössler, David I. Forrester, William L. Mason, Xavier Morin, Hans Pretzsch & Bastien Castagneyrol
While it is widely acknowledged that forest biodiversity contributes to climate change mitigation through improved carbon sequestration, conversely how climate affects tree species diversity - forest productivity relationships is still poorly understood. We combined the results of long-term experiments where forest mixtures and corresponding monocultures were compared on the same site to estimate the yield of mixed-species stands at a global scale, and its response to climatic factors. We found positive mixture effects on productivity...

Data from: Environment and host as large-scale controls of ectomycorrhizal fungi

Sietse Van Der Linde, Laura M. Suz, C. David L. Orme, Filipa Cox, Henning Andreae, Endla Asi, Bonnie Atkinson, Sue Benham, Christopher Carroll, Nathalie Cools, Bruno De Vos, Hans-Peter Dietrich, Johannes Eichhorn, Joachim Germann, Tine Grebenc, Hyun S. Gweon, Karin Hansen, Frank Jacob, Ferdinand Kristöfel, Pawel Lech, Miklos Manninger, Jan Martin, Henning Meesenburg, Päivi Merilä, Manuel Nicolas … & Martin I. Bidartondo
Explaining the large-scale diversity of soil organisms that drive biogeochemical processes—and their responses to environmental change—is critical. However, identifying consistent drivers of belowground diversity and abundance for some soil organisms at large spatial scales remains problematic. Here we investigate a major guild, the ectomycorrhizal fungi, across European forests at a spatial scale and resolution that is—to our knowledge—unprecedented, to explore key biotic and abiotic predictors of ectomycorrhizal diversity and to identify dominant responses and thresholds...

Data from: Boreal tree growth exhibits decadal-scale ecological memory to drought and insect defoliation, but no negative response to their interaction

Malcolm S. Itter, L D'Orangeville, Andria Dawson, Daniel Kneeshaw, Louis Duchesne & Andrew O. Finley
1. Interactions between drought and insect defoliation may dramatically alter forest function under novel climate and disturbance regimes, but remain poorly understood. We empirically tested two important hypotheses regarding tree responses to drought and insect defoliation: 1) trees exhibit delayed, persistent, and cumulative growth responses to these stressors; 2) physiological feedbacks in tree responses to these stressors exacerbate their impacts on tree growth. These hypotheses remain largely untested at a landscape scale, yet are critical...

Data from: Inferring selection in instances of long‐range colonization: the Aleppo pine (Pinus halepensis) in the Mediterranean Basin

Rose Ruiz Daniels, Richard S. Taylor, María Jesús Serra-Varela, Giovanni G. Vendramin, Santiago C. González-Martínez & Delphine Grivet
Teasing apart the effects of natural selection and demography on current allele frequencies is challenging, due to both processes leaving a similar molecular footprint. In particular, when attempting to identify selection in species that have undergone a recent range expansion, the increase of genetic drift at the edges of range expansions (“allele surfing”) can be a confounded factor. To address this potential issue, we first assess the long-range colonisation history of the Aleppo pine across...

Data from: Coupled land use and ecological models reveal emergence and feedbacks in socio‐ecological systems

Nicholas W. Synes, Calum Brown, Stephen C. F. Palmer, Greta Bocedi, Patrick E. Osborne, Kevin Watts, Janet Franklin & Justin M. J. Travis
Understanding the dynamics of socio‐ecological systems is crucial to the development of environmentally sustainable practices. Models of social or ecological sub‐systems have greatly enhanced such understanding, but at the risk of obscuring important feedbacks and emergent effects. Integrated modelling approaches have the potential to address this shortcoming by explicitly representing linked socio‐ecological dynamics. We developed a socio‐ecological system model by coupling an existing agent‐based model of land‐use dynamics and an individual‐based model of demography and...
