Long- and short-read metabarcoding technologies reveal similar spatio-temporal structures in fungal communities

Brendan Furneaux, Mohammad Bahram, Anna Rosling, Nourou Yorou & Martin Ryberg
Fungi form diverse communities and play essential roles in many terrestrial ecosystems, yet there are methodological challenges in taxonomic and phylogenetic placement of fungi from environmental sequences. To address such challenges we investigated spatio-temporal structure of a fungal community using soil metabarcoding with four different sequencing strategies: short amplicon sequencing of the ITS2 region (300--400\ bp) with Illumina MiSeq, Ion Torrent Ion S5, and PacBio RS II, all from the same PCR library, as well...

Data from: Evaluating predictive performance of statistical models explaining wild bee abundance in a mass-flowering crop

Maria Blasi Romero, Ignasi Bartomeus, Riccardo Bommarco, Vesna Gagic, Michael Garratt, Andrea Holzschuh, David Kleijn, Sandra A.M. Lindström, Peter Olsson, Chiara Polce, Simon G. Potts, , Jeroen Scheper, Henrik G. Smith, Ingolf Steffan-Dewenter & Yann Clough
Wild bee populations are threatened by current agricultural practices in many parts of the world, which may put pollination services and crop yields at risk. Loss of pollination services can potentially be predicted by models that link bee abundances with landscape-scale land-use, but there is little knowledge on the degree to which these statistical models are transferable across time and space. This study assesses the transferability of models for wild bee abundance in a mass-flowering...

Data from: Landscape complexity promotes resilience of biological pest control to climate change

Benjamin Feit, Nico Blüthgen, Eirini Daouti, Cory Straub, Michael Traugott & Mattias Jonsson
Increased climate variability as a result of anthropogenic climate change can threaten the functioning of ecosystem services. However, diverse responses to climate change among species (response diversity) can provide ecosystems with resilience to this growing threat. Measuring and managing response diversity and resilience to global change are key ecological challenges. Here, we develop a novel index of climate resilience of ecosystem services, exemplified by calculating the thermal resilience of predator communities providing biological pest control....

Archival and modern DNA SNP data of 13 Baltic salmon populations

Johan Östergren
Intra-species genetic homogenization arising from anthropogenic impacts is a major threat for biodiversity. However, few taxa have sufficient historical material to systematically quantify long-term genetic changes. Using archival DNA collected over ~100 years, we assessed spatio-temporal genetic change in Atlantic salmon populations across the Baltic Sea, an area heavily impacted by hydropower exploitation and associated large-scale mitigation stocking. Analysis was carried out by screening 82 SNPs in 1680 individuals from 13 Swedish rivers. We found...

Interactions between local and global drivers determine long-term trends in boreal forest understory vegetation

Per-Ola Hedwall, Jaime Uria-Diez, Jörg Brunet, Lena Gustafsson, Anna-Lena Axelsson & Joachim Strengbom
Aim: Global change effects on forest ecosystems are increasingly claimed to be context dependent, indicated by interactions between global and local environmental drivers. Most examples of such context dependencies originate from temperate systems, while limited research comes from the boreal biome. Here we set out to test if interactions between climate warming, nitrogen deposition, land-use change resulting in increasing forest density and soil pH drive long-term changes of understory vegetation in boreal forests. Location: Sweden...

Microsatellite variation in Nordic semi-domestic reindeer

Knut Røed, Kjersti Kvie, Bård-Jørgen Bårdsen, Sauli Laaksonen, Hannes Lohi, Juoko Kumpula, Kjell-Åke Aronsson, Birgitta Åhman, Jørn Våge & Øystein Holand
We have analyzed DNA microsatellites and the mitochondrial control region in reindeer from 31 different husbandry areas in Norway, Sweden and Finland in order to better understand the processes that underlie the genetic variability of the Nordic domestic herds. The distinct differentiation found in the nuclear markers but less so in the mitochondrial marker, gives evidence of an origin from a common ancestral population which later evolved into the two main gene pools characterizing the...

Åsa Lankinen & Mattias Larsson
The data set contains Gas Chromatography and Mass Spectrometry (GCMS) analysis data from headspace collections of volatiles from the herb Collinsia heterophylla (Plantaginaceae) covered in Toppits oven bags. Plants were sampled for 5 hours with Porapak Q filters. 200 ng of anethole was added as an internal standard to each sample. Each GCMS file contains a sample from an individual potted plant or a control with only flower pots and soil. Individual plants analyzed by...

Boreal forest fertilization leads to functional homogenization of ground beetle assemblages

Antonio Rodríguez, Anne-Maarit Hekkala, Jorgen Sjögren, Joachim Strengbom & Therese Löfroth
1. Intensive fertilization of young spruce forest plantations (i.e. “nutrient optimization”) has the potential to meet increasing demands for carbon sequestration and biomass production from boreal forests. However, its effects on biodiversity, other than the homogenization of ground-layer plant communities, are widely unknown. 2. We sampled ground beetles (Coleoptera: Carabidae) in young spruce forest plantations of southern Sweden, within a large-scale, replicated ecological experiment initiated in 2012, where half of forest stands were fertilized every...

A tipping-point in carbon storage when forest expands into tundra is related to mycorrhizal recycling of nitrogen

Karina E Clemmensen, Mikael B Durling, Anders Michelsen, Sara Hallin, Roger D Finlay & Björn D Lindahl
Tundra ecosystems are global belowground sinks for atmospheric CO2. Ongoing warming-induced encroachment by shrubs and trees risks turning this sink into a CO2 source, resulting in a positive feedback on climate warming. To advance mechanistic understanding of how shifts in mycorrhizal types affect long-term carbon (C) and nitrogen (N) stocks, we studied small-scale soil depth profiles of fungal communities and C-N dynamics across a subarctic-alpine forest-heath vegetation gradient. Belowground organic stocks decreased abruptly at the...

Learning from long time series of harvest and population data - Swedish insights for European goose management

Niklas Liljebäck
Goose management in Europe is faced by multiple challenges, as some species are declining and in need of conservation actions, while other populations have become very abundant, resulting in calls for increased harvest. Sweden has long-term series of harvest data and counts of breeding and autumn-staging geese. We used national data (indices) for greylag goose, bean goose, and Canada goose to study shifts in temporal trends and correlative patterns, and to infer possible causal links...

Data from: Maternal allocation in relation to weather, predation, and social factors in a colonial cooperative bird

Rita Fortuna, Matthieu Paquet, André C. Ferreira, Liliana R. Silva, Franck Theron, Claire Doutrelant & Rita Covas
Females may adjust prenatal allocation in relation to ecological conditions that affect reproductive success, such as weather conditions or predation risk. In cooperative breeders, helpers might also influence reproductive success and previous studies suggest that females can lay smaller eggs or larger clutches when breeding with more helpers. Although recent work suggests that helper effects can vary according to climatic variables, how social and ecological factors interact to shape prenatal allocation is poorly understood. Here,...

Community phenology of insects on oak – local differentiation along a climatic gradient

Adam Ekholm
Climate change is advancing the onset of phenological events, with the rate of advance varying among species and trophic levels. In addition, local populations of the same species may show genetic differences in their response to seasonal cues. If populations of interacting species differ in their response, then climate change may result in geographically varying shifts in the community-level distribution of interaction strength. We explored the magnitude of trophic and species level responses to temperature...

Projected shifts in deadwood bryophytes in Sweden, data used for species distribution modelling and for climate and forest scenario analysis

Swantje Löbel, Boris Schröder-Esselbach & Tord Snäll
Climate change and habitat loss are main threats to forest biodiversity. We fitted ensembles of single species distribution models for 23 deadwood-living bryophyte species in Sweden, based on species records from the Swedish Lifewatch website. This data set comprises the species and environmental data used for species distribution modelling, and coefficients of the fitted single species distribution models (GLM, Poisson point-process, MaxEnt). Based on the fitted species distribution models, we conducted simulations of future species...

Personality, spatiotemporal ecological variation, and resident/explorer movement syndromes in the sleepy lizard

Marcus Michelangeli
Individual variation in movement is profoundly important for fitness and offers key insights into the spatial and temporal dynamics of populations and communities. Nonetheless, individual variation in fine-scale movement behaviours are rarely examined even though animal tracking devices offer the long-term, high-resolution, repeatable data in natural conditions that are ideal for studying this variation. Furthermore, of the few studies that consider individual variation in movement, even fewer also consider the internal traits and environmental factors...

Data from: Reindeer control over subarctic treeline alters soil fungal communities with potential consequences for soil carbon storage

Henni Ylänne, Rieke L. Madsen, Carles Castaño, Daniel B. Metcalfe & Karina E. Clemmensen
Here we present the data and R script from “Reindeer control over subarctic treeline alters soil fungal communities with potential consequences for soil carbon storage” by Henni Ylänne, Rieke L. Madsen, Carles Castaño, Daniel B. Metcalfe and Karina E. Clemmensen (Global Change Biology, 2021). In this study we reported the impacts of grazing regime and mountain birch vicinity on the abundance, diversity and community composition of the soil fungal community, and explored how the soil...

The female pheromone (Z)-4-undecenal mediates flight attraction and courtship in Drosophila melanogaster

Peter Witzgall, Felipe Borrero-Echeverry, Marit Solum, Federica Trona, Erika A. Wallin, Marie Bengtsson, Peter Witzgall & Sebastien Lebreton
Specific mate communication and recognition underlies reproduction and hence speciation. Mate communication evolves during adaptation to ecological niches and makes use of social signals and habitat cues. Our study provides new insights in Drosophila melanogaster premating olfactory communication, showing that female pheromone (Z)-4-undecenal (Z4-11Al) and male pheromone cVA interact with food odour in a sex-specific manner. Furthermore, Z4-11Al, which mediates upwind flight attraction in both sexes, also elicits courtship in experienced males. Twin variants of...

Age at first reproduction in wolves: different patterns of density dependence for females and males

Camilla Wikenros, Morgane Gicquel, Barbara Zimmermann, Øystein Flagstad & Mikael Åkesson
Age at first reproduction constitutes a key life history trait in animals and is evolutionary shaped by fitness benefits and costs of delayed versus early reproduction. The understanding of how intrinsic and extrinsic changes affects age at first reproduction is crucial for conservation and management of threatened species because of its demographic effects on population growth and generation time. For a period of 40 years in the Scandinavian wolf (Canis lupus) population, including the recolonization...

Organic fertilization suppresses aphid growth via carabids in the absence of specialist predators

Guillermo Aguilera Núñez
Biological control by natural enemies is a valuable ecosystem service. The predator community in a crop field is a combination of predators dwelling in the field and those moving into it from the surrounding landscape. The former is mainly affected by field management, the latter more by the composition of the surrounding landscape. Yet, separate and combined effects of local and landscape management on pest suppression have seldom been investigated. We set-up mesocosms within an...

The legacy of forest disturbance on stream ecosystem functioning

André Frainer & Brendan McKie
1. Forest clearance is a pervasive disturbance worldwide, but many of its impacts are regarded as transient, diminishing in intensity as forest recovers. However, forests can take decades to centuries to recover after severe disturbances, and temporal lags in recovery of ecosystem properties for different forest habitats are mostly unknown. This includes forest streams, where most studies of the impacts of forest clearance are restricted to the first years of recovery, typically finding that temporary...

Variation in developmental rates is not linked to environmental unpredictability in annual killifishes

Piotr Rowinski, Will Sowersby, Joacim Näslund, Simon Eckerström-Liedholm, Karl Gotthard & Björn Rogell
Comparative evidence suggests that adaptive plasticity may evolve as a response to predictable environmental variation. However, less attention has been placed on unpredictable environmental variation, which is considered to affect evolutionary trajectories by increasing phenotypic variation (or bet-hedging). Here, we examine the occurrence of bet-hedging in egg developmental rates in seven species of annual killifish that originate from a gradient of variation in precipitation rates, under three treatment incubation temperatures (21°C, 23°C, and 25°C). In...

Disentangling the nonlinear effects of habitat complexity on functional responses

Julien Mocq, Pavel Soukup, Joacim Näslund & David Boukal
1. Structural complexity of habitats modifies trophic interactions by providing refuges and altering predator and prey behaviour. Nonlinear effects on trophic interaction strengths driven by these mechanisms may alter food web dynamics and community structure in response to habitat modifications. However, changes in functional response, the relationship between prey density and feeding rate, along habitat complexity (HC) gradients are little understood. 2. We quantified functional responses along a HC gradient from an entirely unstructured to...

Biochar increases tree biomass in a managed boreal forest, but does not alter N2O, CH4, and CO2 emissions

Roger Grau-Andrés, Melissa RA Pingree, Mats G Öquist, David A Wardle, Marie-Charlotte Nilsson & Michael J Gundale
Biochar soil amendment may provide the forestry sector with a formidable tool to simultaneously sequester carbon (C) in the soil and aboveground by enhancing plant productivity, yet several key uncertainties remain. Crucially, empirical evidence of long-term effects of biochar management on vegetation and on greenhouse gas emissions in forest ecosystems is scarce. Using a large field experiment in a young managed boreal forest in northern Sweden, we investigated the effects of biochar (applied either on...

Environmental and seasonal correlates of capercaillie movement traits in a Swedish wind farm

Jim-Lino Kämmerle, Julia Taubmann, Henrik Andrén, Wolfgang Fiedler & Joy Coppes
Animals continuously interact with their environment through behavioural decisions, rendering the appropriate choice of movement speed and directionality an important phenotypic trait. Anthropogenic activities may alter animal behaviour, including movement. A detailed understanding of movement decisions is therefore of great relevance for science and conservation alike. The study of movement decisions in relation to environmental and seasonal cues requires continuous observation of movement behaviour, recently made possible by high-resolution telemetry. We studied movement traits of...
