Tuomas Kankaanpää, Eero Vesterinen, Bess Hardwick, Niels Martin Martin Schmidt, Tommi Andersson, Paul Eric Aspholm, Isabel Barrio, Niklas Beckers, Joël Bêty, Tone Birkemoe, Melissa DeSiervo, Katherine Drotos, Dorothee Ehrich, Olivier Gilg, Vladimir Gilg, Nils Hein, Toke Høye, Kristian Jakobsen, Camille Jodouin, Jesse Jorna, Mikhail Kozlov, Jean-Claude Kresse, Don-Jean Leandri-Breton, Nicolas Lecomte, Maia Olsen … & Tomas Roslin
Climatic impacts are especially pronounced in the Arctic, which as a region is warming twice as fast as the rest of the globe. Here, we investigate how mean climatic conditions and rates of climatic change impact parasitoid insect communities in 16 localities across the Arctic. We focus on parasitoids in a wide-spread habitat, Dryas heathlands, and describe parasitoid community composition in terms of larval host use (i.e. parasitoid use of herbivorous Lepidoptera versus pollinating Diptera)...

Controls of chlorophyll fluorescence spectra vary among leaves in a boreal forest and over a spring recovery of photosynthesis

Paulina Rajewicz, Chao Zhang, Jon Atherton, Shari Van Wittenberghe, Anu Riikonen, Troy Magney, Beatriz Fernandez-Marin, Jose Ignacio Garcia Plazaola & Albert Porcar-Castell
Chlorophyll fluorescence can be used to track to seasonal dynamics of photosynthesis in boreal forests. However, the relationship between chlorophyll fluorescence and photosynthesis is affected by biochemical and morphological factors, which vary across time and space as a function of light environment, species, and environmental conditions. We investigated how various factors, and their spatio-temporal dynamics during spring recovery of photosynthesis in a boreal forest, affect spatio-temporal variation in chlorophyll fluorescence spectra. The factors under consideration...

Data from: Social transmission in the wild reduces predation pressure on novel prey signals

Liisa Hämäläinen, William Hoppitt, Hannah Rowland, Johanna Mappes, Anthony Fulford, Sebastian Sosa & Rose Thorogood
Social transmission of information is taxonomically widespread and could have profound effects on the ecological and evolutionary dynamics of animal communities. Demonstrating this in the wild, however, has been challenging. Here we show by field experiment that social transmission among predators can shape how selection acts on prey defences. Using artificial prey and a novel approach in statistical analyses of social networks, we find that blue tit (Cyanistes caeruleus) and great tit (Parus major) predators...

Specialist predation covaries with colour polymorphism in tawny owls

Patrik Karell, Kio Kohonen & Katja Koskenpato
Understanding intraspecific phenotypic variation in prey specialisation can help to predict how long-term changes in prey availability affect the viability of these phenotypes and their persistence. Generalists are favoured when the main food resources are unpredictable compared to specialists, which track the availability of the main prey and are more vulnerable to changes in the main food resource. Intraspecific heritable melanin-based colour polymorphism is considered to reflect adaptations to different environments. We studied colour morph-specific...

Data from: Urbanization affects oak–pathogen interactions across spatial scales

Laura Van Dijk, Xoaquin Moreira, Anna Barr, Luis Abdala-Roberts, Bastien Castagneyrol, Maria Faticov, Bess Hardwick, Jan Ten Hoopen, Raul De La Mata, Ricardo Matheus Pires, Tomas Roslin, Dmitry Schigel, Bart Timmermans & Ayco Tack
The world is rapidly urbanizing, thereby transforming natural landscapes and changing the abundance and distribution of organisms. However, insights into the effects of urbanization on species interactions, and plant-pathogen interactions in particular, are lacking. We investigated the effects of urbanization on powdery mildew infection on Quercus robur at continental and within-city scales. At the continental scale, we compared infection levels between urban and rural areas of different-sized cities in Europe, and investigated whether plant traits,...

Smith, Tibor Szep & Chris Van Turnhout
1. Global climate change is driving species’ distributions towards the poles and mountain tops during both non-breeding and breeding seasons, leading to changes in the composition of natural communities. However, the degree of season differences in climate-driven community shifts has not been thoroughly investigated at large spatial scales. 2. We compared the rates of change in the community composition during both winter (non-breeding season) and summer (breeding) and their relation to temperature changes. 3. Based...

Climate change reshapes the eco-evolutionary dynamics of a Neotropical seed dispersal system

Lilian Sales, W. Daniel Kissling, Mauro Galetti, Babak Naimi & Mathias Pires
Aim: Global changes will redistribute biodiversity, reshaping ecological interactions and ecosystem processes. The distribution decoupling of plants and their mutualistic seed dispersers, for instance, may have overlooked eco-evolutionary effects. How animal-dispersed plants will respond to changes in the distribution of their seed dispersers is, however, an open question. Here, we forecast the consequences of climate change and frugivory interactions for the spatial distribution and seed size evolution of a Neotropical palm. Location: Atlantic forests of...

Metabolic rate and behavioral traits in Salmo trutta

Jenni Prokkola
The behavior of organisms can be subject to human induced selection such as that arising from fishing. Angling is expected to induce mortality on fish with bold and explorative behavior, which are behaviors commonly linked to a high standard metabolic rate. We studied the transgenerational response of brown trout (Salmo trutta) to angling-induced selection by examining the behavior and metabolism of 1-year-old parr between parents that were or were not captured by experimental fly fishing....

Data and code from: Accounting for species interactions is necessary for predicting how arctic arthropod communities respond to climate change

Nerea Abrego, Tomas Roslin, Tea Huotari, Yinqiu Ji, Niels Martin Schmid, Jiaxin Wang, Douglas W. Yu & Otso Ovaskainen
Species interactions are known to structure ecological communities. Still, the influence of climate change on biodiversity has primarily been evaluated by correlating individual species distributions with local climatic descriptors, then extrapolating into future climate scenarios. We ask whether predictions on arctic arthropod response to climate change can be improved by accounting for species interactions. For this, we use a 14-year-long, weekly time series from Greenland, resolved to the species level by mitogenome mapping. During the...

Diatom biogeography in freshwaters – new insights from between-region comparisons and the role of unmeasured environmental factors

Janne Soininen
Diatom biogeography has attracted increased attention especially over the past two decades. However, due to covariance between space and environment, diatom biogeographical studies suffer from the fundamental problem of reliably evaluating the relative roles of dispersal processes versus local environment in shaping diatom distributions. Using between-region comparisons, we investigate whether diatom community differences stem partly from dispersal effects or are purely driven by the local environment. The data used comprise diatom presence-absence records and associated...

Data from: Living, dead, and absent trees - How do moth outbreaks shape small-scale patterns of soil organic matter stocks and dynamics at the Subarctic mountain birch treeline?

Nele Meyer, Yi Xu, Katri Karjalainen, Sylwia Adamczyk, Christina Biasi, Lona Van Delden, Angela Martin, Kevin Mganga, Kristiina Myller, Outi-Maaria Sietiö, Otso Suominen & Kristiina Karhu
Mountain birch forests (B. pubescens Ehrh. ssp. czerepanovii) at the subarctic treeline not only benefit from global warming, but are also increasingly affected by caterpillar outbreaks from foliage-feeding geometrid moths. Both of these factors have unknown consequences on soil organic carbon (SOC) stocks and biogeochemical cycles. We measured SOC stocks down to the bedrock under living trees and under two stages of dead trees (12 and 55 years since moth outbreak) and treeless tundra in...

Small RNA expression and miRNA modification dynamics in human oocytes and early embryos

Pauliina Paloviita, Christel Hydén-Granskog, Juha S. Tapanainen, Timo Tuuri & Sanna Vuoristo
Small non-coding RNAs (sRNAs) play important roles during the oocyte-to-embryo transition (OET), when the maternal phenotype is reprogrammed, and the embryo genome is gradually activated. The transcriptional program driving early human development has been studied with the focus mainly on protein-coding RNAs, and expression dynamics of sRNAs remains largely unexplored. We profiled sRNAs in human oocytes and early embryos using an RNA-sequencing (RNA-seq) method suitable for low inputs of material. We show that OET in...

Data from: The evolution of polymorphism in the warning coloration of the Amazonian poison frog Adelphobates galactonotus

Diana Rojas, Paolo Momigliano, Albertina Pimentel Lima, Pedro Ivo Simões, Rachel Y. Dudaniec, Teresa C. S. Avila-Pires, Marinus S. Hoogmoed, Youszef O. C. Bitar, Igor Luis Kaefer, Adolfo Amézquita & Adam Stow
While intraspecific variation in aposematic signals can be selected for by different predatory responses, their evolution is also contingent on other processes shaping genetic variation. We evaluate the relative contributions of selection, geographic isolation and random genetic drift to the evolution of aposematic color polymorphism in the poison frog Adelphobates galactonotus, distributed throughout eastern Brazilian Amazonia. Dorsal coloration was measured for 111 individuals and genetic data were obtained from 220 individuals at two mitochondrial genes...

Challenges and opportunities of species distribution modelling of terrestrial arthropod predators

Stefano Mammola, Julien Pétillon, Axel Hacala, Jeremy Monsimet, Sapho-Lou Marti, Pedro Cardoso & Denis Lafage
Aim. Species distribution models (SDMs) have emerged as essential tools in the equipment of many ecologists, useful to explore species distributions in space and time and answering an assortment of questions related to biogeography, climate change biology and conservation biology. Historically, most SDM research concentrated on well-known organisms, especially vertebrates. In recent years, these tools are becoming increasingly important for predicting the distribution of understudied invertebrate taxa. Here, we reviewed the literature published on main...

Differences in thermal tolerance between parental species could fuel thermal adaptation in hybrid wood ants

Raphael Martin-Roy, Elisa Nygård, Pierre Nouhaud & Jonna Kulmuni
Genetic variability is essential for adaptation and could be acquired via hybridization with a closely related lineage. We use ants to investigate thermal adaptation and the link between temperature and genetic variation arising from hybridization. We test for differences in cold and heat tolerance between Finnish Formica polyctena and Formica aquilonia wood ants and their naturally occurring hybrids. Using workers, we find the parental individuals differ in both cold and heat tolerances and express thermal...

Data from: Predicting spatial patterns of Sindbis virus (SINV) infection risk in Finland using vector, host and environmental data

Ruut Uusitalo
Pogosta disease is a mosquito-borne infection, caused by the Sindbis virus (SINV) with epidemics of febrile rash and arthritis in Northern Europe and South Africa. The virus is maintained in a transmission cycle between birds and mosquitoes. Resident grouse and migratory birds play a significant role as amplifying hosts and various mosquito species, including Aedes cinereus, Culex pipiens, Cx. torrentium and Culiseta morsitans are documented vectors. As specific treatments are not available for SINV infections...

Pervasive admixture and the spread of a large-lipped form in a cichlid fish radiation

Will Sowersby, José Cerca, Bob Wong, Topi Lehtonen, David Chapple, Mariana Leal-Cardin, Marta Barluenga & Mark Ravinet
Adaptive radiations have proven important for understanding the mechanisms and processes underlying biological diversity. The convergence of form and function, as well as admixture and adaptive introgression, are common in adaptive radiations. However, distinguishing between these two scenarios remains a challenge for evolutionary research. The Midas cichlid species complex (Amphilophus spp.) is a prime example of adaptive radiation, with phenotypic diversification occurring at various stages of genetic differentiation. One species, A. labiatus, has large fleshy...

Data from: Taxon-level assessment of the data collection quality in Atlas Florae Europaeae: insights from the case of Rosa (Rosaceae) in Eastern Europe

Anatoly Khapugin, Anna Sołtys-Lelek, Nikolai Fedoronchuk, Albert Muldashev, Vladimir Agafonov, Elena Kazmina, Vladimir Vasjukov, Olga Baranova, Irina Buzunova, Ludmila Teteryuk, Dmitry Dubovik, Zigmantas Gudžinskas, Toomas Kukk, Alexey Kravchenko, Andrey Yena, Mikhail Kozhin & Alexander Sennikov
By the method of data re-collection and re-assessment, we tested the completeness of distribution areas of the species and species aggregates of Rosa in Eastern Europe as mapped in volume 13 of Atlas Florae Europaeae, and discussed insights into the issues connected with the data. We have found many new occurrences which are additions to the published maps: 1068 records of species and 570 records of species aggregates. The new occurrences are listed with references...

Alternative developmental and transcriptomic responses to host plant water limitation in a butterfly metapopulation

Aapo Kahilainen, Vicencio Oostra, Panu Somervuo, Guillaume Minard & Marjo Saastamoinen
The dataset is from a study examining the effects of host plant water stress on the developmental and transcriptomic responses of its specialist Lepidopteran herbivore. The study combines host plant metabolic profiling with development assays and full-transcriptome sequencing of herbivore larvae. First, we profiled metabolic differences between well-watered and water-limited ribwort plantain (Plantago lanceolata) using proton nuclear magnetic resonance spectroscopy (1H-NMR). Second, we tested how performance of developing Glanville fritillary (Melitaea cinxia) larvae was affected...

Alpine ibex simulation files

Deborah Leigh, Heidi Lischer, Frederic Guillaume, Christine Grossen & Torsten Gunther
Identifying local adaptation in bottlenecked species is essential for conservation management. Selection detection methods have an important role in species management plans, assessments of adaptive capacity, and looking for responses to climate change. Yet, the allele frequency changes exploited in selection detection methods are similar to those caused by the strong neutral genetic drift expected during a bottleneck. Consequently, it is often unclear what accuracy selection detection methods have across bottlenecked populations. In this study,...
