Data from: Annual variation in breeding success in boreal forest grouse

Per Wegge, Robert Moss & Jørund Rolstad
Knowledge of the temporal variation in reproductive success and its key driving factors is crucial in predicting animal population persistence. Few studies have examined the effects of a range of explanatory factors operating simultaneously on the same population over a long period. Based on 41 years of monitoring (1979–2019), we tested prevailing hypotheses about drivers of annual variation in breeding success in two sympatric species of boreal forest grouse – the capercaillie (Tetrao urogallus) and...

To evaluate progress on political biodiversity objectives, biodiversity monitoring provides information on whether intended results are being achieved. Despite scientific proof that monitoring and evaluation increase the (cost) efficiency of policy measures, cost estimates for monitoring schemes are seldom available, hampering their inclusion in policy programme budgets. Empirical data collected from 12 case studies across Europe were used in a power analysis to estimate the number of farms that would need to be sampled per...

Data from: Global transcriptome changes in perennial ryegrass during early infection by pink snow mould

Mallikarjuna Rao Kovi, Mohamed Abdelhalim, Anil Kunapareddy, Åshild Ergon, Anne Marte Tronsmo, May Bente Brurberg, Ingerd Skow Hofgaard, Torben Asp & Odd Arne Rognli
Lack of resistance to pink snow mould (Microdochium nivale) is a major constraint for adaptation of perennial ryegrass (Lolium perenne L.) to continental regions with long-lasting snow cover at higher latitudes. Almost all investigations of genetic variation in resistance have been performed using cold acclimated plants. However, there may be variation in resistance mechanisms that are functioning independently of cold acclimation. In this study our aim was to identify candidate genes involved in such resistance...

Data from: A collection of European sweet cherry phenology data for assessing climate change

Bénédicte Wenden, José Antonio Campoy, Julien Lecourt, Gregorio López Ortega, Michael Blanke, Sanja Radičević, Elisabeth Schüller, Andreas Spornberger, Danilo Christen, Hugo Magein, Daniela Giovannini, Carlos Campillo, Svetoslav Malchev, José Miguel Peris, Mekjell Meland, Rolf Stehr, Gérard Charlot & José Quero-García
Professional and scientific networks built around the production of sweet cherry (Prunus avium L.) led to the collection of phenology data for a wide range of cultivars grown in experimental sites characterized by highly contrasted climatic conditions. We present a dataset of flowering and maturity dates, recorded each year for one tree when available, or the average of several trees for each cultivar, over a period of 37 years (1978 - 2015). Such dataset is...

Data from: Fire history in a western Fennoscandian boreal forest as influenced by human land use and climate

Jørund Rolstad, Ylva-Li Blanck & Ken Olaf Storaunet
Knowing the historical variation in fire regimes is instrumental in managing forests today and in predicting what may happen in the future. By cross-dating 745 fire scars in 378 samples of remnant Scots pines, we delineated 254 individual forest fires during the past 700 years in a 74-km2 section of Trillemarka-Rollagsfjell Nature Reserve in south-central Norway. Fire sizes, numbers, burn rates, and frequencies were compared with historical climate proxies, vegetation maps, and written sources. The...

Data from: Genetic substructure and admixture as important factors in linkage disequilibrium-based estimation of effective number of breeders in recovering wildlife populations

Alexander Kopatz, Hans Geir Eiken, Julia Schregel, Jouni Aspi, Ilpo Kojola & Snorre B. Hagen
The number of effective breeders (Nb) and effective population size (Ne) are population parameters reflective of evolutionary potential, susceptibility to stochasticity, and viability. We have estimated these parameters using the linkage disequilibrium-based approach with LDNE through the latest phase of population recovery of the brown bears (Ursus arctos) in Finland (1993–2010; N = 621). This phase of the recovery was recently documented to be associated with major changes in genetic composition. In particular, differentiation between...

Data from: Ecological impact assessments of alien species in Norway

Westergaard, Frode Ødegaard, Sandra Åström, Hallvard Elven, Anders Endrestøl, Øivind Gammelmo, Bjørn Arild Hatteland, Halvor Solheim, Björn Nordén, Leif Sundheim, Venche Talgø, Tone Falkenhaug, Bjørn Gulliksen, Anders Jelmert, Eivind Oug … & Lisbeth Gederaas
Due to globalisation, trade and transport, the spread of alien species is increasing dramatically. Some alien species become ecologically harmful by threatening native biota. This can lead to irreversible changes in local biodiversity and ecosystem functioning, and, ultimately, to biotic homogenisation. We risk-assessed all alien plants, animals, fungi and algae, within certain delimitations, that are known to reproduce in Norway. Mainland Norway and the Arctic archipelago of Svalbard plus Jan Mayen were treated as separate...

Data from: Translocation of an arctic seashore plant reveals signs of maladaptation to altered climatic conditions

Maria Hällfors, Susanna Lehvävirta, Tone Aandahl, Iida-Maria Lehtimäki, Lars Ola Nilsson, Anna-Liisa Ruotsalainen, Leif Schulman & Marko Hyvärinen
Ongoing anthropogenic climate change alters the local climatic conditions to which species may be adapted. Information on species’ climatic requirements and their intraspecific variation is necessary for predicting the effects of climate change on biodiversity. We used a climatic gradient to test whether populations of two allopatric varieties of an arctic seashore herb (Primula nutans ssp. finmarchica) show adaptation to their local climates and how a future warmer climate may affect them. Our experimental set-up...

Data from: Explaining European fungal fruiting phenology with climate variability

Carrie Andrew, Einar Heegaard, Klaus Høiland, Beatrice Senn-Irlet, Thomas W. Kuyper, Irmgard Krisai-Greilhuber, Paul M. Kirk, Jacob Heilmann-Clausen, Alan C. Gange, Simon Egli, Claus Bässler, Ulf Büntgen, Lynne Boddy & Håvard Kauserud
Here we assess the impact of geographically dependent (latitude, longitude and altitude) changes in bioclimatic (temperature, precipitation and primary productivity) variability on fungal fruiting phenology across Europe. Two main nutritional guilds of fungi, saprotrophic and ectomycorrhizal, were further separated into spring and autumn fruiters. We used a path‐analysis to investigate how biogeographic patterns in fungal fruiting phenology coincided with seasonal changes in climate and primary production. Across central to northern Europe, mean fruiting varied by...

Imprints of latitude, host taxon and decay stage on fungus-associated arthropod communities

Janne Koskinen, Nerea Abrego, Eero Vesterinen, Torsti Schulz, Tomas Roslin & Tommi Nyman
Interactions among fungi and insects involve hundreds of thousands of species. While insect communities on plants have formed some of the classic model systems in ecology, fungus-based communities and the forces structuring them remain poorly studied by comparison. We characterize the arthropod communities associated with fruiting bodies of eight mycorrhizal basidiomycete fungus species from three different orders along a 1200-km latitudinal gradient in northern Europe. We hypothesized that—matching the pattern seen for most insect taxa...

Dataset from: A curated DNA barcode reference library for parasitoids of northern European cyclically outbreaking geometrid moths

Tommi Nyman, Saskia Wutke, Elina Koivisto, Tero Klemola, Mark Shaw, Tommi Andersson, Håkon Haraldseide, Snorre Hagen, Ryosuke Nakadai & Kai Ruohomäki
Large areas of forests are annually damaged or destroyed by outbreaking insect pests. Understanding the factors that trigger and terminate such population eruptions has become crucially important, as plants, plant-feeding insects, and their natural enemies may respond differentially to the ongoing changes in the global climate. In northernmost Europe, climate-driven range expansions of the geometrid moths Epirrita autumnata and Operophtera brumata have resulted in overlapping and increasingly severe outbreaks. Delayed density-dependent responses of parasitoids are...

Neutral processes related to regional bee commonness and dispersal distances are important predictors of plant-pollinator networks along gradients of climate and landscape conditions

Markus Arne Sydenham, Zander Venter, Stein Moe, Katrine Eldegard, Michael Kuhlmann, Trond Reitan, Claus Rasmussen, Robert Paxton, Yoko Dupont, Astrid Skrindo, Megan Nowell, Stein Hegland, Anders Nielsen, Jens Olesen & Graciela Rusch
Understanding how niche-based and neutral processes contribute to the spatial variation in plant-pollinator interactions is central to designing effective pollination conservation schemes. Such schemes are needed to reverse declines of wild bees and other pollinating insects and to promote pollination services to wild and cultivated plants. We used data on wild bee interactions with plants belonging to the four tribes Loteae, Trifolieae, Anthemideae, and either spring- or summer-flowering Cichorieae, sampled systematically along a 682km latitudinal...

Comparative analysis of the anthelmintic efficacy of European heather extracts on Teladorsagia circumcincta and Trichostrongylus colubriformis egg hatching and larval motility

Francesca Shepherd, Caroline Chylinski, Michael R. Hutchings, Joana Lima, Ross Davidson, Robert Kelly, Alastair Macrae, Juha-Pekka Salminen, Marica T. Engström, Veronika Maurer, Håvard Steinshamn, Susanne Fittje, Angela Morell Perez, Rocío Rosa García & Spiridoula Athanasiadou
Abstract Background Gastrointestinal nematode (GIN) control is traditionally achieved with the use of anthelmintic drugs, however due to regulations in organic farming and the rise in anthelmintic resistance, alternatives are sought after. A promising alternative is the use of bioactive plant feeding due to the presence of plant secondary metabolites (PSMs) such as proanthocyanidins (PAs). This study focussed on the perennial shrub heather (Ericaceae family), a plant rich in PAs, highly abundant across Europe and...

Data from: Contributions of feather microstructure to eider down insulation properties

Liliana D'Alba, Thomas Holm Carlsen, Árni Ásgeirsson, Matthew D. Shawkey & Jon Einar Jonsson
Insulation is an essential component of nest structure that helps provide incubation requirements for birds. Many species of waterfowl breed in high latitudes where rapid heat loss can necessitate a high energetic input from parents and use down feathers to line their nests. Common eider Somateria mollissima nest down has exceptional insulating properties but the microstructural mechanisms behind the feather properties have not been thoroughly examined. Here, we hypothesized that insulating properties of nest down...

Data from: Sociodemographic factors modulate the spatial response of brown bears to vacancies created by hunting

Shane C. Frank, Martin Leclerc, Fanie Pelletier, Frank Rosell, Jon E. Swenson, Richard Bischof, Jonas Kindberg, Hans Geir Eiken, Snorre B. Hagen, Andreas Zedrosser & Jon. E. Swenson
1.There is a growing recognition of the importance of indirect effects from hunting on wildlife populations, e.g., social and behavioral changes due to harvest, which occur after the initial offtake. Nonetheless, little is known about how the removal of members of a population influences the spatial configuration of the survivors. 2.We studied how surviving brown bears (Ursus arctos) used former home ranges that had belonged to casualties of the annual bear hunting season in southcentral...

Data from: Spatial mismatch between management units and movement ecology of a partially migratory ungulate

Erling L. Meisingset, Leif Egil Loe, Øystein Brekkum, Richard Bischof, Inger Maren Rivrud, Unni Støbet Lande, Barbara Zimmermann, Vebjørn Veiberg & Atle Mysterud
1. Population-level management is difficult to achieve if wildlife routinely crosses administrative boundaries, as is particularly frequent for migratory populations. However, the degree of mismatch between management units and scales at which ecological processes operate has rarely been quantified. Such insight is vital for delimiting functional population units of partially migratory species common in northern forest ecosystems. 2. We combined an extensive dataset of 412 GPS-marked red deer (Cervus elaphus) across Norway with information on...

Data from: Norway and Sweden Green Roof (GF) plant data

Joel Lönnqvist, Hans Martin Hanslin & Birgitte Gisvold Johannessen
Standard succulent vegetation mixes developed mostly in temperate climates are being increasingly used on green roofs in different climate zones with uncertain outcome regarding vegetation survival and cover. We investigated vegetation on green roofs at nine temperate, cold and/or wet locations in Norway and Sweden covering wide ranges of latitude, mean annual temperature, annual precipitation, frequencies of freeze-thaw cycles and longest annual dry period. The vegetation on the roofs were surveyed in two consecutive years,...

Data from: Climate change and bird reproduction: warmer springs benefit breeding success in boreal forest grouse

Per Wegge & Jorund Rolstad
Global warming is predicted to adversely affect reproduction of birds, especially in northern latitudes. A recent study in Finland inferred that declining populations of black grouse Tetrao tetrix could be attributed to advancement of the time of mating and chicks hatching too early – a support of the mismatch hypothesis. Here, we examine the breeding success of sympatric capercaillie T. urogallus and black grouse over a 38-year period in southeast Norway. Breeding season temperatures increased,...

Using ecological context to interpret spatiotemporal variation in natural selection

Elena Albertsen, Elena Albertsen, Øystein Opedal, Geir Bolstad, Rocio Barrales, Thomas Hansen, Christophe Pelabon & W. Scott Armbruster
Spatiotemporal variation in natural selection is expected, but difficult to estimate. Pollinator-mediated selection on floral traits provides a good system for understanding and linking variation in selection to differences in ecological context. We studied pollinator-mediated selection in five populations of Dalechampia scandens (Euphorbiaceae) in Costa Rica and Mexico. Using a nonlinear path-analytical approach, we assessed several functional components of selection, and linked variation in pollinator-mediated selection across time and space to variation in pollinator assemblages....

Data from: Multi-level patterns in population genetics: variogram series detects a hidden isolation-by- distance- dominated structure of Scandinavian brown bears Ursus arctos

Julia Schregel, Jaanus Remm, Hans Geir Eiken, Jon E. Swenson, Urmas Saarma & Snorre B. Hagen
1. Large-scale pattern-oriented approaches are useful to understand the multi-level processes that shape the genetic structure of a population. Matching the scales of patterns and putative processes is both a key to success and a challenge. 2. We have developed a simple statistical approach, based on variogram analysis, that identifies multiple spatial scales where the population pattern, in this case genetic structure, have highest expression (i.e. the spatial scales at which the strength of patterning...
