Francis J. Burdon, Yaohui Bai, Marta Reyes, Manu Tamminen, Phillip Staudacher, Simon Mangold, Heinz Singer, Katja Räsänen, Adriano Joss, Scott D. Tiegs, Jukka Jokela, Rik I. L. Eggen & Christian Stamm
Multiple anthropogenic drivers are changing ecosystems globally, with a disproportionate and intensifying impact on freshwater habitats. A major impact of urbanisation are inputs from wastewater treatment plants (WWTPs). Initially designed to greatly reduce nutrient loads, WWTPs increasingly release a multitude of micropollutants (i.e., synthetic chemicals) and organisms (including antibiotic resistant bacteria) to receiving environments. This pollution may have pervasive impacts on biodiversity and ecosystem services. Viewed through multiple lenses of macroecological and ecotoxicological theory, we...

Niche differentiation and evolution of the wood decay machinery in the invasive fungus Serpula lacrymans

Jaqueline Hess, Sudhagar V. Balasundaram, Renee I Bakkemo, Elodie Drula, Bernard Henrissat, Nils Högberg, Daniel Eastwood & Inger Skrede
Ecological niche breadth and the mechanisms facilitating its evolution are fundamental to understanding adaptation to changing environments, persistence of generalist and specialist lineages and the formation of new species. Woody substrates are structurally complex resources utilized by organisms with specialized decay machinery. Wood-decaying fungi represent ideal model systems to study evolution of niche breadth, as they vary greatly in their host range and preferred decay stage of the substrate. In order to dissect the genetic...

Close relatives in population samples: Evaluation of the consequences for genetic stock identification

Johan Östergren, Stefan Palm, John Gilbey & Johan Dannewitz
Determining the origin of individuals in mixed population samples is key in many ecological, conservation and management contexts. Genetic data can be analyzed using Genetic Stock Identification (GSI), where the origin of single individuals is determined using Individual Assignment (IA) and population proportions are estimated with Mixed Stock Analysis (MSA). In such analyses, allele frequencies in a reference baseline are required. Unknown individuals or mixture proportions are assigned to source populations based on the likelihood...

Robustness of a meta‐network to alternative habitat loss scenarios

Micaela Santos, Luciano Cagnolo, Tomas Roslin, Emmanuel F. Ruperto, María Laura Bernaschini & Diego P. Vázquez
Studying how habitat loss affects the tolerance of ecological networks to species extinction (i.e. their robustness) is key for our understanding of the influence of human activities on natural ecosystems. With networks typically occurring as local interaction networks interconnected in space (a meta-network), we may ask how the loss of specific habitat fragments affects the overall robustness of the meta-network. To address this question, for an empirical meta-network of plants, herbivores and natural enemies we...

Accounting for environmental variation in co‐occurrence modelling reveals the importance of positive interactions in root‐associated fungal communities

Nerea Abrego, Tomas Roslin, Tea Huotari, Ayco J.M. Tack, Björn D. Lindahl, Gleb Tikhonov, Panu Somervuo, Niels Martin Schmidt, Otso Ovaskainen & Ayco J. M. Tack
Understanding the role of interspecific interactions in shaping ecological communities is one of the central goals in community ecology. In fungal communities, measuring interspecific interactions directly is challenging because these communities are composed of large numbers of species, many of which are unculturable. An indirect way of assessing the role of interspecific interactions in determining community structure is to identify the species co-occurrences that are not constrained by the environmental conditions. In this study, we...

Moose (Alces alces) parturition dates, Sweden

Wiebke Neumann, Navinder J. Singh, Fredrik Stenbacka, Jonas Malmsten, Kjell Wallin, John P. Ball & Göran Ericsson
In northern environments, the period of access to high-quality forage is limited, exerting strong selective pressure to optimize the timing of parturition. We analysed timing and variation in moose parturition dates of 555 females at 18 study sites across 12ᵒ of latitude (56-68ᵒ N, 1,350 km) in Sweden. We found evidence for a spatial match of parturition timing to vegetation onset, but no evidence that moose adjust parturition to vegetation onset in a given year....

1. Agricultural intensification is one of the main drivers of species loss worldwide, but there is still a lack of information about its effect on functional diversity of arable weeds communities. 2. Using a large scale pan European study including 786 fields within 261 farms from eight countries, we analysed differences in the taxonomic and functional diversity of arable weeds assemblages across different levels of agricultural intensification in. We estimated weed species frequency in each...

Data from: Evolution and disappearance of sympatric Coregonus albula in a changing environment - a case study of the only remaining population pair in Sweden

Stefan Palm
During the past 50 years Fennoscandian populations of spring-spawning Baltic cisco (Coregonus albula), sympatric to common autumn-spawners, have declined or disappeared; e.g., three out of four known spring-spawning populations in Sweden are regarded as extinct. Over the same period, climate has changed and populations have been subject to other anthropogenic stressors. We compared historic (1960s) and recent (1990-2000s) morphological data from the still existent sympatric cisco populations in Lake Fegen, Sweden. Phenotypic changes were found...

Globally, plant-soil feedbacks are weak predictors of plant abundance

Kurt Reinhart, Jonathan Bauer, Sarah McCarthy-Neumann, Andrew MacDougall, José Hierro, Mariana Chiuffo, Scott Mangan, Johannes Heinze, Joana Bergmann, Jasmin Joshi, Richard Duncan, Jeff Diaz, Paul Kardol, Gemma Rutten, Markus Fischer, Wim Van Der Putten, T. Bezemer & John Klironomos
Plant-soil feedbacks (PSFs) have been shown to strongly affect plant performance under controlled conditions, and PSFs are thought to have far reaching consequences for plant population dynamics and the structuring of plant communities. However, thus far the relationship between PSF and plant species abundance in the field is not consistent. Here, we synthesize PSF experiments from tropical forests to semiarid grasslands, and test for a positive relationship between plant abundance in the field and PSFs...

Data from: Assessing the usefulness of Citizen Science Data for habitat suitability modelling: opportunistic reporting versus sampling based on a systematic protocol

Laura Henckel, Ute Bradter, Mari Jönsson, Nick Isaac & Tord Snäll
Aim: To evaluate the potential of models based on opportunistic reporting (OR) compared to models based on data from a systematic protocol (SP) for modelling species distributions. We compared model performance for eight forest bird species with contrasting spatial distributions, habitat requirements, and rarity. Differences in the reporting of species were also assessed. Finally, we tested potential improvement of models when inferring high quality absences from OR based on questionnaires sent to observers. Location: Both...

Migration of tagged silver eels in the Atlantic 2006 - 2014

Known and estimated locations of silver European eels in the Atlantic from 2006 to 2014 derived from popup satellite tags and archival tags. Other data associated with the tagging experiments such as the length, weight, fat percentage, Pankhurst index and Fin index are also included. Locations were either known (from transmitted positions) or were estimated based on the temperature at depth data recorded by electronic tags (latitude) and the timing of steep dives at dawn...

Scripts and files for \"Small-scale population divergence is driven by local larval environment in a temperate amphibian\"

Patrik Rödin Mörch, Hugo Palejowski, Maria Cortazar-Chinarro, Simon Kärvemo, Alex Richter-Boix, Jacob Höglund & Anssi Laurila
Genomic variation within and among populations is shaped by the interplay between natural selection and the effects of genetic drift and gene flow. Adaptive divergence can be found in small scale natural systems even when population sizes are small and the potential for gene flow is high, suggesting that local environments exert selection pressures strong enough to counteract the opposing effects of drift and gene flow. Here, we investigated genomic differentiation in nine moor frog...

Data from: Impact of a recolonizing, cross-border carnivore population on ungulate harvest in Scandinavia

Camilla Wikenros, Håkan Sand, Johan Månsson, Erling Maartmann, Petter Wabakken & Barbara Zimmermann
Predation from large carnivores and human harvest are the two main mortality factors affecting the dynamics of many ungulate populations. We examined long-term moose (Alces alces) harvest data from two countries that share cross-border populations of wolves (Canis lupus) and their main prey moose. We tested how a spatial gradient of increasing wolf territory density affected moose harvest density and age and sex composition of the harvested animals (n = 549,310), along a latitudinal gradient...

Data from: Ecological speciation in European whitefish is driven by a large‐gaped predator

Gunnar Öhlund, Mats Bodin, Karin Nilsson, Sven-Ola Öhlund, Kenyon Mobley, Alan Hudson, Mikael Peedu, Åke Brännström, Pia Bartels, Kim Præbel, Catherine Hein, Petter Johansson & Göran Englund
Lake‐dwelling fish that form species pairs/flocks characterized by body size divergence are important model systems for speciation research. Although several sources of divergent selection have been identified in these systems, their importance for driving the speciation process remains elusive. A major problem is that in retrospect, we cannot distinguish selection pressures that initiated divergence from those acting later in the process. To address this issue, we studied the initial stages of speciation in European whitefish...

Crop diversity benefits carabid and pollinator communities in landscapes with semi-natural habitats

Guillermo Aguilera Núñez, Tomas Roslin, Kirsten Miller, Giovanni Tamburini, Klaus Birkhofer, Berta Caballero-Lopez, Sandra Lindström, Erik Öckinger, , Adrien Rusch, Henrik Smith & Riccardo Bommarco
1. In agricultural landscapes, arthropods provide essential ecosystem services such as biological pest control and pollination. Intensified crop management practices and homogenization of landscapes have led to declines among such organisms. Semi-natural habitats, associated with high numbers of these organisms, are increasingly lost from agricultural landscapes but diversification by increasing crop diversity has been proposed as a way to reverse observed arthropod declines and thus restore ecosystem services. However, whether or not an increase in...

Data from: Island properties dominate species traits in determining plant colonizations in an archipelago system

Mikael Von Numers, Sami Aikio, Satu Ramula & Anne Muola
The extrinsic determinants hypothesis emphasizes the essential role of environmental heterogeneity in species’ colonization. Consequently, high resident species diversity can increase community susceptibility to colonizations because good habitats may support more species that are functionally similar to colonizers. On the other hand, colonization success is also likely to depend on species traits. We tested the relative importance of environmental characteristics and species traits in determining colonization success using census data of 587 vascular plant species...

Water stress and insect herbivory interactively reduce crop yield while the insect pollination benefit is conserved

Chloé Raderschall, Giulia Vico, Ola Lundin, Astrid Taylor & Riccardo Bommarco
Climate change is predicted to hamper crop production due to precipitation deficits and warmer temperatures inducing both water stress and increasing herbivory due to more abundant insect pests. Consequently, crop yields will be impacted simultaneously by abiotic and biotic stressors. Extensive yield losses due to such climate change stressors might, however, be mitigated by ecosystem services such as insect pollination. We examined the single and combined effects of water stress, insect herbivory and insect pollination...

Data for: Microclimate structures communities, predation and herbivory in the High Arctic

Tuomas Kankaanpää, Nerea Abrego, Eero Vesterinen & Tomas Roslin
In a warming world, changes in climate may result in species-level responses as well as changes in community structure through knock-on effects on ecological interactions such as predation and herbivory. Yet, the links between these responses at different levels are still inadequately understood. Assessing how microclimatic conditions affect each of them at local scales provides information essential for understanding the consequences of macroclimatic changes projected in the future. Focusing on the rapidly changing High Arctic,...

Population structure of five native sheep breeds of Sweden estimated with high density SNP genotypes

Christina Marie Rochus, Elisabeth Jonas & Anna M. Johansson
Background Native Swedish sheep breeds are part of the North European short-tailed sheep group; characterized in part by their genetic uniqueness. Our objective was to study the population structure of native Swedish sheep. Five breeds were genotyped using the 600 K SNP array. Dalapäls and Klövsjö sheep are from the middle of Sweden; Gotland and Gute sheep from Gotland, an island in the Baltic Sea; and Fjällnäs sheep from northern Sweden. We studied population structure...

Stochastic processes and ecological connectivity drive stream invertebrate community responses to short-term drought

Romain Sarremejane, Amélie Truchy, Brendan McKie, Heikki Mykrä, Richard Johnson, Ari Huusko, Ryan Sponseller & Timo Muotka
1. Community responses to and recovery from disturbances depend on local (e.g. presence of refuges) and regional (connectivity to recolonization sources) factors. Droughts are becoming more frequent in boreal regions, and are likely to constitute a severe disturbance for boreal stream communities where organisms largely lack adaptations to such hydrological extremes. 2. We conducted an experiment in 24 seminatural stream flumes to assess the effects of local and regional factors on the responses of benthic...

Data from: Influence of canopy openness, ungulate exclosure, and low-intensity fire for improved oak regeneration in temperate Europe

Linda Petersson, Daniel Dey, Annika Felton, Emile Gardiner & Magnus Löf
Failed oak regeneration is widely reported in temperate forests and has been linked in part to changed disturbance regimes and land-use. We investigated if the North American fire-oak hypothesis could be applicable to temperate European oaks (Q. robur, Q. petraea) using a replicated field experiment with contrasting canopy openness, protection against ungulate browsing (fencing/no fencing), and low-intensity surface fire (burn/no burn). Survival, relative height growth (RGRH), browsing damage on naturally regenerated oaks (≤300 cm tall),...

Wild strawberry shows genetic variation in tolerance but not resistance to a generalist herbivore

Minggang Wang, Anne Muola, Peter Anderson & Johan Stenberg
Plants’ defenses against herbivores usually include both resistance and tolerance mechanisms. Their deployment has predominantly been studied in either single plant genotypes, or multiple genotypes exposed to single herbivores. In natural situations, however, most plants are attacked by multiple herbivores. Therefore, aims of this study were to assess and compare effects of single and multiple herbivores on plant resistance and tolerance traits, and the consequences for overall plant performance. For this, we exposed multiple genotypes...

Genetic diversity of farmed and wild Rufiji tilapia (Oreochromis urolepis urolepis) populations

Christos Palaiokostas
Rufiji tilapia (Oreochromis urolepis urolepis) is an endemic cichlid in Tanzania. In addition to its importance for biodiversity conservation, Rufiji tilapia is also attractive for farming due to its high growth-rate, salinity tolerance, and the production of all-male hybrids when crossed with Nile tilapia (Oreochromis niloticus). The aim of the current study was to assess the genetic diversity and population structure of both wild and farmed Rufiji tilapia populations in order to inform conservation and...

Data from: Fire and grazing controlling a tropical tree line: Effects of long‐term grazing exclusion in Bale Mountains, Ethiopia

Maria Ulrika Johansson & Anders Granström
Aims: Tropical tree lines are often associated with abrupt shifts in vegetation, soils and disturbance regimes, but the underlying mechanisms are poorly understood. We analysed the role of grazing, fuels and fire in maintaining a sharp tree line with flammable heathland above non-flammable forest. Location: Bale Mountains, Ethiopia. Methods: Grazing exclosures, repeated vegetation sampling, soil analyses and burning and sowing experiments along an altitudinal gradient with Hagenia abyssinica forest, Erica trimera forest and Erica heathland;...
