Data from: Exploring a Pool-seq only approach for gaining population genomic insights in non-model species

Sara Kurland, Chris Wheat, Maria De La Paz Celorio-Mancera, Verena Kutschera, Jason Hill, Anastasia Andersson, Carl Johan Rubin, Leif Andersson, Nils Ryman & Linda Laikre
Developing genomic insights is challenging in non-model species for which resources are often scarce and prohibitively costly. Here, we explore the potential of a recently established approach using Pool-seq data to generate a de novo genome assembly for mining exons, upon which Pool-seq data is used to estimate population divergence and diversity. We do this for two pairs of sympatric populations of brown trout (Salmo trutta); one naturally sympatric set of populations and another pair...

Host plant phenology, insect outbreaks and herbivore communities – The importance of timing

Adam Ekholm, Ayco J. M. Tack, Pertti Pulkkinen & Tomas Roslin
1. Climate change may alter the dynamics of outbreak species by changing the phenological synchrony between herbivores and their host plants. As host plant phenology has a genotypic component that may interact with climate, infestation levels among genotypes might change accordingly. When the outbreaking herbivore is active early in the season, its infestation levels may also leave a detectable imprint on herbivores colonizing the plant later in the season. 2. In this study, we first...

Data from: Carbon use efficiency of mycorrhizal fungal mycelium increases during the growing season but decreases with forest age across a Pinus sylvestris chronosequence

Andreas Hagenbo, David Hadden, Karina E. Clemmensen, Achim Grelle, Stefano Manzoni, Meelis Mölder, Alf Ekblad & Petra Fransson
1. In boreal forest soils, mycelium of mycorrhizal fungi is pivotal for regulating soil carbon (C) cycling and storage. The carbon use efficiency (CUE), a key parameter in C cycling models, can inform on the partitioning of C between microbial biomass, and potential soil storage, and respiration. Here we test the dependency of mycorrhizal mycelial CUE on stand age and seasonality in managed boreal forest stands. 2. Based on mycelial production and respiration estimates, derived...

Data from: Subsidy type and quality determine direction and strength of trophic cascades in arthropod food web in agro‐ecosystems

Laura G. A. Riggi & Riccardo Bommarco
1. The subsidy hypothesis states that communities receiving nutrient subsidies will demonstrate top-down trophic cascades where predators indirectly increase plant biomass. This has been both confirmed and refuted, which might depend on whether the subsidy has mainly targeted the plant or the detrital food-web compartment, and on the subsidy quality. This is particularly poorly understood for terrestrial communities such as heavily subsidized agroecosystems. 2. Using cages covering 4 m2 of ground in a long-term agricultural...

Data from: Trophic interactions and abiotic factors drive functional and phylogenetic structure of vertebrate herbivore communities across the Arctic tundra biome

James D.M. Speed, Ina A. Skjelbred, Isabel C. Barrio, Michael D. Martin, Dominique Berteaux, C. Guillermo Bueno, Katie S. Christie, Bruce C. Forbes, Jennifer Forbey, Daniel Fortin, Jon-Arvid Grytnes, Katrine S. Hoset, Nicolas Lecomte, Bryndis Marteinsdottir, Jesper B. Mosbacher, Åshild O. Pedersen, Virve Ravolainen, Eileen C. Rees, Anna Skarin, Natalya Sokolova, Andrew H. Thornhill, Ingunn Tombre & Eeva M. Soininen
Communities are assembled from species that evolve or colonise a given geographic region, and persist in the face of abiotic conditions and interactions with other species. The evolutionary and colonisation histories of communities are characterised by phylogenetic diversity, while functional diversity is indicative of abiotic and biotic conditions. The relationship between functional and phylogenetic diversity infers whether species functional traits are divergent (differing between related species) or convergent (similar among distantly related species). Biotic interactions...

Data from: Linking plant genes to insect communities: identifying the genetic bases of plant traits and community composition

Hilary L. Barker, Jennifer F. Riehl, Carolina Bernhardsson, Kennedy Rubert-Nason, Liza Holeski, Pär K. Ingvarsson & Richard L. Lindroth
Community genetics aims to understand the effects of intraspecific genetic variation on community composition and diversity, thereby connecting community ecology with evolutionary biology. Thus far, research has shown that plant genetics can underlie variation in the composition of associated communities (e.g., insects, lichen, endophytes), and those communities can therefore be considered as extended phenotypes. This work, however, has been conducted primarily at the plant genotype level and has not identified the key underlying genes. To...

Data from: Impact of plant functional group and species removals on soil and plant nitrogen and phosphorus across a retrogressive chronosequence

David Wardle, Michael Gundale, Paul Kardol, Marie-Charlotte Nilsson Hegethorn & Nicolas Fanin
1. In the prolonged absence of catastrophic disturbance, ecosystem retrogression occurs, which is characterized by declining soil nitrogen (N) and phosphorus (P) availability, increasing plant and soil N to P ratios, and reduced plant biomass and productivity. It is, however, largely unknown as to how the effects of plant communities on soil nutrients change during retrogression or might contribute to declining nutrient availability as retrogression proceeds. 2. We studied a well characterized system of 30...

Climate and host genotype jointly shape tree phenology, disease levels and insect attacks

Maria Faticov, Adam Ekholm, Tomas Roslin & Ayco Tack
One of the best known ecological consequences of climate change is the advancement of spring phenology. Yet, we lack insights into how changes in climate interact with intraspecific genetic variation in shaping spring and autumn phenology, and how such changes in phenology will translate into seasonal dynamics of tree-associated organisms. To elucidate the impact of warming and tree genotype on spring and autumn phenology, as well as the consequences for the population dynamics of a...

Hydropeaking affects germination and establishment of riverbank vegetation

María D. Bejarano, Álvaro Sordo-Ward, Carlos Alonso, Roland Jansson & Christer Nilsson
Hydropeaking, defined as frequent and rapid variation in flow in regulated rivers with hydropower plants over a short period of time, usually sub-daily to weekly, alters hydraulic parameters such as water levels or flow velocity and exerts strong impacts on fluvial ecosystems. We evaluated the effects of hydropeaking on riverbank vegetation, specifically assessing the germination and establishment of seedlings and cuttings of plant species representing a variation in traits. We used seeds and seedlings and...

Mesophication in temperate Europe: a dendrochronological reconstruction of tree succession and fires in a mixed deciduous stand in Białowieża Forest / supporting data

Andreea Petronela Spinu, Mats Niklasson & Ewa Zin
The attached data was gathered to investigate the successional changes in Bialowieza Forest mixed-deciduous stands by reconstructing the long-term tree population dynamics (tree-ring data). Traces of fires were documented from a 43ha area to explore whether fire was involved in shaping the succession of this habitat.

Chiarello, Jean-François Cosson, Will Cresswell, Filibus Danjuma Dami, Jens Dauber, Christopher R. Dickman, Raphael K. Didham, David P. Edwards, Fabio Z. Farneda, Yoni Gavish, Thiago Gonçalves-Souza, Demetrio Luis Guadagnin, Mickaël Henry, Adrià López-Baucells, Heike Kappes … & Yaron Ziv
Habitat destruction is the single greatest anthropogenic threat to biodiversity. Decades of research on this issue have led to the accumulation of hundreds of data sets comparing species assemblages in larger, intact, habitats to smaller, more fragmented, habitats. Despite this, little synthesis or consensus has been achieved, primarily because of non‐standardized sampling methodology and analyses of notoriously scale‐dependent response variables (i.e., species richness). To be able to compare and contrast the results of habitat fragmentation...

Data from: High ecosystem service delivery potential of small woodlands in agricultural landscapes

Alicia Valdés, Jonathan Lenoir, Pieter De Frenne, Emilie Andrieu, Jorg Brunet, Olivier Chabrerie, Sara Cousins, Marc Deconchat, Pallieter De Smedt, Martin Diekmann, Steffen Ehrmann, Emilie Gallet-Moron, Stefanie Gaertner, Brice Giffard, Karin Hansen, Martin Hermy, Annette Kolb, Vincent Leroux, Jaan Liira, Jessica Lindgren, Ludmilla Martin, Tobias Naaf, Taavi Paal, Willem Proesmans, Michael Scherer-Lorenzen … & Guillaume Decocq
Global forest loss and fragmentation have strongly increased the frequency of forest patches smaller than a few hectares. Little is known about the biodiversity and ecosystem service supply potential of such small woodlands in comparison to larger forests. As it is widely recognized that high biodiversity levels increase ecosystem functionality and the delivery of multiple ecosystem services, small, isolated woodlands are expected to have a lower potential for ecosystem service delivery than large forests hosting...

Data from: Habitat diversity associated with island size and environmental filtering control the species richness of rock-savanna plants in neotropical inselbergs

Ludovic Henneron, Corinne Sarthou, Jean-Christophe De Massary & Jean-François Ponge
Disentangling the multiple factors controlling species diversity is a major challenge in ecology. Island biogeography and environmental filtering are two influential theories emphasizing respectively island size and isolation, and the abiotic environment, as key drivers of species richness. However, few attempts have been made to quantify their relative importance and investigate their mechanistic basis. Here, we applied structural equation modelling, a powerful method allowing test of complex hypotheses involving multiple and indirect effects, on an...

Data from: Herbivore resistance in congeneric and sympatric Nothofagus species is not related to leaf habit

Frida I. Piper, Michael J. Gundale, Tomás Fuenzalida & Alex Fajardo
Premise of the study Two fundamental hypotheses on herbivore resistance and leaf habit are the resource availability hypothesis (RAH) and the carbon-nutrient balance hypothesis (CNBH). The RAH predicts higher constitutive resistance by evergreens and the CNBH predicts higher induced resistance by deciduous species. Although support for these hypotheses is mixed, they have rarely been examined in congeneric species. Methods We compared leaf constitutive and induced resistance (as leaf polyphenols and tannin concentrations, and damage level...

Data from: The forgotten season: the impact of autumn phenology on a specialist insect herbivore community on oak

Adam Ekholm, Ayco J. M. Tack, Kjell Bolmgren & Tomas Roslin
1. Variation in spring phenology – like tree budburst – affects the structure of insect communities, but impacts of autumn phenology have been neglected. Many plant species have recently delayed their autumn phenology, and the timing of leaf senescence may be important for herbivorous insects. 2. This study explored how an insect herbivore community associated with Quercus robur is influenced by variation in autumn phenology. For this, schools were asked to record, across the range...

Data from: Nonlinearity of root trait relationships and the root economics spectrum

Deliang Kong, Junjian Wang, Huifang Wu, Oscar J. Valverde-Barrantes, Ruili Wang, Hui Zeng, Paul Kardol, Haiyan Zhang & Yulong Feng
The root economics spectrum (RES), a common hypothesis postulating a tradeoff between resource acquisition and conservation traits, is being challenged by conflicting relationships between root diameter, tissue density (RTD) and root nitrogen concentration (RN). Here, we analyze a global trait dataset of absorptive roots for over 800 plant species. For woody species (but not for non-woody species), we find nonlinear relationships between root diameter and RTD and RN, which stem from the allometric relationship between...

Data from: Tolerance and overcompensation to infection by Phytophthora infestans in the wild perennial climber Solanum dulcamara

Laura Masini, Laura J. Grenville-Briggs, Erik Andreasson, Lars Råberg & Asa Lankinen
Studies of infection by Phytophthora infestans—the causal agent of potato late blight—in wild species can provide novel insights into plant defense responses, and indicate how wild plants might be influenced by recurrent epidemics in agricultural fields. In the present study, our aim was to investigate if different clones of Solanum dulcamara (a relative of potato) collected in the wild differ in resistance and tolerance to infection by a common European isolate of P. infestans. We...

Data from: The interplay of landscape composition and configuration: new pathways to manage functional biodiversity and agro-ecosystem services across Europe

Emily A. Martin, Matteo Dainese, Yann Clough, András Báldi, Riccardo Bommarco, Vesna Gagic, Michael Garratt, Andrea Holzschuh, David Kleijn, Anikó Kovács-Hostyánszki, Lorenzo Marini, Simon G. Potts, Henrik G. Smith, Diab Al Hassan, Matthias Albrecht, Georg K. S. Andersson, Josep Asis, Stephanie Aviron, Mario Balzan, Laura Baños-Picón, Ignasi Bartomeus, Peter Batary, Françoise Burel, Berta Caballero-López, Elena D. Concepcion … & Ingolf Steffan-Dewenter
Managing agricultural landscapes to support biodiversity and ecosystem services is a key aim of a sustainable agriculture. However, how the spatial arrangement of crop fields and other habitats in landscapes impacts arthropods and their functions is poorly known. Synthesising data from 49 studies (1515 landscapes) across Europe, we examined effects of landscape composition (% habitats) and configuration (edge density) on arthropods in fields and their margins, pest control, pollination and yields. Configuration effects interacted with...

Data from: Flow restoration and the impacts of multiple stressors on fish communities in regulated rivers

Emma Göthe, Erik Degerman, Leonard Sandin, Joel Segerseten, Carl Tamario & Brendan G. McKie
River regulation for hydropower is undertaken worldwide, causing profound alterations to hydrological regimes and running water habitats. Regulated catchments are often subjected to additional stressors, arising inter alia from agriculture, forestry and industry, which are likely to interact with impacts of river regulation on fish and other biota. Such interactions are poorly understood, hindering planning of effective mitigation and restoration. We investigated fish responses to increased discharge (as a restoration measure) in regulated rivers in...
