Data from: Active farmsteads are year-round strongholds for farmland birds

Martin Šálek, Miroslav Bažant & Michał Żmihorski
1. Farmland birds have experienced substantial declines over recent decades and various conservation measures have been designed to halt their massive decrease. The effectiveness of these measures is however limited, due to inappropriate identification of crucial breeding and wintering habitats. Identification of appropriate habitats, like farmsteads, and understanding seasonal changes in species richness and abundance of farmland birds within these habitats may therefore be key for farmland bird conservation. 2. We investigated the effect of...

Data from: Contribution of European forests to safeguard wild honey bee populations

Fabrice Requier, Yoan Paillet, Fabien Laroche, Benjamin Rutschmann, Jie Zhang, Fabio Lombardi, Miroslav Svoboda & Ingolf Steffan-Dewenter
Recent studies reveal the use of tree cavities by wild honey bee colonies in European forests. This highlights the conservation potential of forests for a highly threatened component of the native entomofauna in Europe, but currently no estimate of potential wild honey bee population sizes exists. Here, we analysed the tree cavity densities of 106 forest areas across Europe and inferred an expected population size of wild honey bees. Both forest and management types affected...

Martin Mikoláš, Marek Svitok, Radek Bače, Garrett Meigs, William Keeton, Heather Keith, Arne Buechling, Volodymyr Trotsiuk, Kurt Bollmann, Krešimir Begovič, Vojtěch Čada, Oleh Chaskovskyy, Dheeraj Ralhan, Martin Dušátko, Matej Ferenčík, Michal Frankovič, Rhiannon Gloor, Jeňýk Hofmeister, Pavel Janda, Ondrej Kameniar, Daniel Kozák, Jana Lábusová, Linda Majdanová, Thomas Nagel, Jakob Pavlin … & Miroslav Svoboda
With accelerating environmental change, understanding the influence of forest disturbances and trade-offs between biodiversity and carbon dynamics is of high socio-economic importance. Most studies, however, have assessed immediate or short-term effects of disturbance, while long-term impacts remain poorly understood. Here, using a tree-ring-based approach, we modelled the effect of 250 years of disturbances on present-day biodiversity indicators and carbon dynamics in well-preserved European temperate primary forests. Our results indicated that disturbance legacies spanning centuries shaped...

Tree canopy accession strategy changes along the latitudinal gradient of temperate Northeast Asia

Jan Altman, Pavel Janda, Olga Ukhvatkina, Anna Vozmishcheva, Alexander Omelko, Jiří Doležal, Pavel Krestov, Alexander Zhmerenetsky & Jong-Suk Song
Aim: Understanding how natural forest disturbances control tree regeneration is key to predict the consequences of globally accelerating forest diebacks on carbon stocks and forest biodiversity. Tropical cyclones (TCs) are important drivers of forest dynamics in Eastern Asia and it is predicted that their importance will increase. However, little is known about TC impact on forest regeneration. Location: Latitudinal gradient from south Korea (33°N) to the Russian Far East (45°N). Time period: Last 300 years....

Comparative phylogeography reveals consistently shallow genetic diversity in a mitochondrial marker in Antarctic bdelloid rotifers

Diego Fontaneto, Zeyneb Vildan Cakil, Giuseppe Garlasché, Nataliia Iakovenko, Andrea Di Cesare, Ester M. Eckert, Roberto Guidetti, Lina Hamdan, Karel Janko, Dzmitry Lukashanets, Lorena Rebecchi, Stefano Schiaparelli, Tommaso Sforzi, Eva Štefková Kašparová, Alejandro Velasco-Castrillón & Elizabeth Walsh
Aim: The long history of isolation of the Antarctic continent, coupled with the harsh ecological conditions of freezing temperatures could affect the patterns of genetic diversity in the organisms living there. We aim (1) to test whether such pattern can be seen in a mitochondrial marker of bdelloid rotifers, a group of microscopic aquatic and limno-terrestrial animals, and (2) to speculate on the potential mechanisms driving the pattern. Location: focus on Antarctica. Taxon: Rotifera Bdelloidea....

Longitudinal evidence for immunosenescence and inflammaging in free-living great tits

Martin Těšický, Tereza Krajzingrová, Zuzana Świderská, Kamila Syslová, Barbora Bílková, Jiří Eliáš, Hana Velová, Jana Svobodová, Petra Bauerová, Tomáš Albrecht & Vinkler Michal
The first-line effector mechanisms of immune defence, including inflammation and oxidative burst, contribute significantly to host-pathogen resistance. Whether these immune responses undergo age-related changes in birds remains unknown. Here, we tracked selected inflammatory parameters in 54 free-living great tits (Parus major) of known age, captured repeatedly over three consecutive years, with the aims to investigate long-term repeatability and age-dependent changes in cellular oxidative burst responsiveness upon in vitro stimulation with bacterial lipopolysaccharide (LPS), and to...

The observations can be used to obtain allometric size-biomass models. This work was supported by the Natural Environment Research Council award...

Data from: Population biology of establishment in New Zealand hedgehogs inferred from genetic and historical data: conflict or compromise?

Barbora Bolfikova, Adam Konečný, Miriam Pfäffle, Jasmin Skuballa & Pavel Hulva
The crucial steps in biological invasions, related to the shaping of genetic architecture and the current evolution of adaptations to a novel environment, usually occur in small populations during the phases of introduction and establishment. However, these processes are difficult to track in nature due to invasion lag, large geographic and temporal scales compared with human observation capabilities, the frequent depletion of genetic variance, admixture and other phenomena. In this study, we compared genetic and...

Data from: Metabolomic and transcriptomic data on major metabolic/biosynthetic pathways in workers and soldiers of the termite Prorhinotermes simplex (Isoptera: Rhinotermitidae) and chemical synthesis of intermediates of defensive (E)-nitropentadec-1-ene biosynthesis

Anna Jirošová, Andrej Jančařík, Riya C. Menezes, Olga Bazalová, Klára Dolejšová, Heiko Vogel, Pavel Jedlička, Aleš Buček, Jana Brabcová, Pavel Majer, Robert Hanus & Aleš Svatoš
Production of nitro compounds has only seldom been recorded in arthropods. The aliphatic nitroalkene (E)-nitropentadec-1-ene (NPD), identified in soldiers of the termite genus Prorhinotermes, was the first case documented in insects in early seventies. Yet, the biosynthetic origin of NPD has long remained unknown. We previously proposed that NPD arises through the condensation of amino acids glycine and/or l-serine with tetradecanoic acid along a biosynthetic pathway analogous to the formation of sphingolipids. Here, we provide...

Data from: Host compatibility as a critical factor in management unit recognition: population-level differences in mussel-fish relationships

Karel Douda, Jerzy Sell, Lucie Kubíková-Peláková, Pavel Horký, Agnieszka Kaczmarczyk & Monika Mioduchowska
1. The recognition of management units (MUs) that respect inter-population distinctions in management needs is central to many biological applications addressing species conservation, biological invasions and ecosystem processes. 2. We present a methodological approach for the evaluation of population-level differences in the host compatibility of natural populations of affiliate (dependent) species. Two experiments were performed to diagnose the sources of variability in the relationships between an endangered freshwater mussel Unio crassus and its host fish...

Data from: Crop-to-wild hybridization in cherries – empirical evidence from Prunus fruticosa

Lenka Macková, Petr Vít & Tomas Urfus
Crop cultivation can lead to genetic swamping of indigenous species and thus pose a serious threat for biodiversity. The rare Eurasian tetraploid shrub Prunus fruticosa (ground cherry) is suspected of hybridizing with cultivated allochthonous tetraploid P. cerasus and autochthonous diploid P. avium. Three Prunus taxa (447 individuals of P. fruticosa, 43 of P. cerasus and 73 of P. avium) and their hybrids (198 individuals) were evaluated using analysis of absolute genome size/ploidy level and multivariate...

Data from: Species interactions increase the temporal stability of community productivity in Pinus sylvestris-Fagus sylvatica mixtures across Europe

Miren Del Río, Hans Pretzsch, Ricardo Ruiz-Peinado, Evy Ampoorter, Peter Annighöfer, Ignacio Barbeito, Kamil Bielak, Gediminas Brazaitis, Lluis Coll, Lars össler, Marek Fabrika, David I. Forrester, Michael Heym, Václav Hurt, Viktor Kurylyak, Magnus Löf, Fabio Lombardi, Ekaterina Makrickiene, Bratislav Matovic, Frits Mohren, Renzo Motta, Jan Den Ouden, Maciej Pach, Quentin Ponette, Gerhard Schütze … & Lars Drössler
1.There is increasing evidence that species diversity enhances the temporal stability of community productivity in different ecosystems, although its effect at population and tree levels seems to be negative or neutral. Asynchrony in species responses to environmental conditions was found to be one of the main drivers of this stabilizing process. However, the effect of species mixing on the stability of productivity, and the relative importance of the associated mechanisms, remain poorly understood in forest...

Data from: Cuckoos host range is associated positively with distribution range and negatively with evolutionary uniqueness

Federico Morelli, Yanina Benedetti, Anders P. Moller, Wei Liang & Luis M. Carrascal
1. The evolutionary distinctiveness (ED) score is a measure of phylogenetic isolation that quantifies the evolutionary uniqueness of a species. 2. Here, we compared the ED score of parasitic and non-parasitic cuckoo species worldwide, to understand whether parental care or parasitism represent the largest amount of phylogenetic uniqueness. Next, we focused only on 46 cuckoo species characterized by brood parasitism with a known number of host species, we explored the associations among ED score, number...

Data from: Global pattern of nest predation is disrupted by climate change in shorebirds

Vojtěch Kubelka, Miroslav Šálek, Pavel Tomkovich, Zsolt Végvári, Robert P. Freckleton & Tamás Székely
Ongoing climate change is thought to disrupt trophic relationships, with consequences for complex interspecific interactions, yet the effects of climate change on species interactions are poorly understood, and such effects have not been documented at a global scale. Using a single database of 38,191 nests from 237 populations, we found that shorebirds have experienced a worldwide increase in nest predation over the past 70 years. Historically, there existed a latitudinal gradient in nest predation, with...

Data from: Quantifying natural disturbances using a large-scale dendrochronological reconstruction to guide forest management

Vojtěch Čada, Volodymyr Trotsiuk, Pavel Janda, Martin Mikolas, Radek Bace, Thomas Nagel, Robert Morrissey, Alan Tepley, Ondřej Vostarek, Krešimir Begović, Oleh Chaskovskyy, Martin Dušátko, Ondrej Kameniar, Daniel Kozák, Jana Lábusová, Jakub Málek, Peter Meyer, Joseph Pettit, Jonathan Schurman, Kristýna Svobodová, Michal Synek, Marius Teodosiu, Karol Ujházy & Miroslav Svoboda
Estimates of historical disturbance patterns are essential to guide forest management aimed at ensuring the sustainability of ecosystem functions and biodiversity. However, quantitative estimates of various disturbance characteristics required in management applications are rare in longer-term historical studies. Thus, our objectives were to: (1) quantify past disturbance severity, patch size, and stand proportion disturbed, and (2) test for temporal and sub-regional differences in these characteristics. We developed a comprehensive dendrochronological method to evaluate an approximately...

Inter-annual repeatability and age-dependent changes in plasma testosterone levels in a longitudinally monitored free-living passerine bird

Martin Těšický, Tereza Krajzingrová, Jiří Eliáš, Hana Velová, Jana Svobodová, Petra Bauerová, Tomáš Albrecht & Michal Vinkler
While seasonal trends in testosterone levels are known from cross-cohort studies, data on testosterone inter-annual individual repeatability in wild birds are rare. Also, our understanding of hormonal age-dependent changes in testosterone levels is limited. We assessed plasma testosterone levels in 105 samples originating from 49 repeatedly captured free-living great tits (Parus major) sampled during the nesting to investigate their relative long-term repeatability and within-individual changes. Furthermore, we examined the inter-annual repeatability of condition-related traits (carotenoid-...

Animal lifestyle affects acceptable mass limits for attached tags

Rory Wilson, Kayleigh Rose, Richard Gunner, Mark Holton, Nikki Marks, Nigel Bennett, Stephen Bell, Joshua Twining, Jamie Hesketh, Carlos Duarte, Neil Bezodis, Milos Jezek, Michael Painter, Vaclav Silovsky, Margaret Crofoot, Roi Harel, John Arnould, Blake Allan, Desley Whisson, Abdulaziz Alagaili & David Scantlebury
Animal-attached devices have transformed our understanding of vertebrate ecology. To minimize any associated harm, researchers have long advocated that tag masses should not exceed 3% of carrier body mass. However, this ignores tag forces resulting from animal movement. Using data from collar-attached accelerometers on 10 diverse free-ranging terrestrial species from koalas to cheetahs, we detail a tag-based acceleration method to clarify acceptable tag mass limits. We quantify animal athleticism in terms of fractions of animal...

Connectivity and succession of open structures as a key to sustaining light-demanding biodiversity in deciduous forests

Petr Kozel, Pavel Sebek, Michal Platek, Jiri Benes, Michal Zapletal, Miroslav Dvorsky, Vojtech Lanta, Jiri Dolezal, Radek Bace, Borivoj Zbuzek & Lukas Cizek
1. European forests are facing a rapid decline of light-demanding biota. This has prompted active interventions to re-establish and maintain partial habitat openness in protected areas. Managers of protected areas, however, need substantially more scientific evidence to support their decisions on where, when, and how to intervene. 2. We investigated the importance of spatial continuity of open forest habitats in different years of succession, using six pairs of experimental clearings established in the formerly open,...

Data from: Establishing a community-wide DNA barcode library as a new tool for arctic research

H. Wirta, G. Várkonyi, C. Rasmussen, R. Kaartinen, N. M. Schmidt, P. D. N. Hebert, M. Barták, G. Blagoev, H. Disney, S. Ertl, P. Gjelstrup, D. J. Gwiazdowicz, L. Huldén, J. Ilmonen, J. Jakovlev, M.

DNA sequences offer powerful tools for describing the members and interactions of natural communities. In this study, we establish the to-date most comprehensive library of DNA barcodes for a terrestrial site, including all known macroscopic animals and vascular plants of an intensively studied area of the High Arctic, the Zackenberg Valley in Northeast Greenland. To demonstrate its utility, we apply the library to identify nearly 20 000 arthropod individuals from two Malaise traps, each operated...

Data from: A new perspective on Melanophloea, Thelocarpella and Trimmatothelopsis: species previously placed in multiple families are united within a single genus in the Acarosporaceae

Kerry Knudsen & James C. Lendemer
Recent molecular phylogenetic studies of the lichen family Acarosporaceae have shown that genera in this group, as traditionally defined, are not monophyletic and that changes are required to accommodate the discovery that taxa with disparate thallus morphologies are often closely related. Here we use phylogenetic inferences of mtSSU sequence data to show that seven species (Acarospora dispersa, A. rhizobola, A. terricola, Melanophloea americana, M. coreana, M. montana and Thelocarpella gordensis), currently placed in four genera...

Data from: Traditional forest management practices stop forest succession and bring back rare plant species

Jan Douda, Karel Boublík, Jana Doudová & Michal Kyncl
Past management practices may continue to influence ecosystem functions and processes for decades, centuries or even longer after they have been abandoned. Until now, few researchers have attempted experiments which test the effects of restoring some of these past management practices on long-term community developmental trajectories. Strong evidence indicates that the diversity of various taxonomic groups declined in European lowland forests in the second half of the 20th century, following the abandonment of some traditional...

Colony-age-dependent variation in cuticular hydrocarbon profiles in subterranean termite colonies

Johnalyn Gordon, Jan Šobotník & Thomas Chouvenc
Cuticular hydrocarbons (CHCs) have, in insects, important physiological and ecological functions, such as protection against desiccation and as semiochemicals in eusocial taxa, including termites. CHCs are, in termites, known to vary qualitatively and/or quantitatively among species, populations, or seasons. Changes to hydrocarbon profile composition have been linked to varying degrees of aggression between termite colonies, although the variability of results among studies suggests that additional factors might have been involved. One source of variability may...

Juggling options: manipulation ease determines primate optimal fruit size choice

Renann H. P. Dias-Silva, Matheus J. Castro Sa, Fabricio B. Baccaro, Pavel Tománek & Adrian A. Barnett
Optimal foraging theory predicts that animals will seek simultaneously to minimize food processing time and maximize energetic gain. To test this hypothesis, we evaluated whether a specialist seed-predator primate forages optimally when choosing among variable-sized thick-husked fruits. Our objects of study were the golden-backed-uacari (Cacajao ouakary, Pitheciidae) and single seeded pods of the macucu tree (Aldina latifolia, Fabaceae). We predicted that golden-backed-uacari will consume fruits of the size class that requires the least time to...

Data from: Along with intraspecific functional trait variation, individual performance is key to resolving community assembly processes

Jana Doudová & Jan Douda
Species contributing high proportions to community biomass strongly influence ecosystem processes within the community. Studies have shown that dominant species may serve as nurse plants, helping to ensure biomass stability of the subordinate species under stress conditions. The question is widely debated as to whether either niche differentiation or neutral processes drive the net outcome of plant interactions within a subordinate plant community. To answer this question, requires precise estimates of individual variation in functional...
