What defines insularity for plants in edaphic islands?

Francisco Emmanuel Méndez Castro, Luisa Conti, Milan Chytrý, Borja Jimenez-Alfaro, Michal Hajek, Michal Horsák, David Zeleny, Marco Malavasi & Gianluigi Ottaviani
The Theory of Island Biogeography postulates that size and isolation are key drivers of biodiversity on islands. This theory has been applied not only to true (e.g. oceanic) islands but also to terrestrial island-like systems (e.g. edaphic islands). Recently, a debate has opened as to whether terrestrial island-like systems function like true islands. However, identifying the effect of insularity in terrestrial systems is conceptually and methodologically challenging because recognizing species source(s) and measuring isolation is...

Eiders, nutrients and eagles: Bottom-up and top-down population dynamics in a marine bird_dataset

Federico Morelli, Karsten Laursen, Marek Svitok, Yanina Benedetti & Anders Pape Møller
The main objective of this long-term study (1978-2016) was to find the underlying factors behind the declining trends of eider Somateria mollissima in the Baltic/Wadden Sea. Specifically, we aimed at quantifying the bottom-up effect of nutrients, through mussel stocks, on reproduction and abundance of eider, and the top-down effects caused by white-tailed eagle Haliaeetus albicilla predation. Bottom-up effects increase marine primary productivity with subsequent effects on food availability for a major mussel predator. Top-down effects...

Interplay of above- and belowground resource limitations: a competition-facilitation shift maintains species coexistence

Jan Douda
Forest ecosystems are commonly characterised by a hierarchy of resources. During a disturbance of a forest community, increased light availability in the understorey can support competitive interactions at the expense of facilitation. This may overwhelm the role of belowground resource heterogeneity in maintaining species coexistence and so result in biotic homogenisation of a site. We re-surveyed species composition while estimating interspecific interactions along a microtopographic (moisture) gradient of a temperate swamp forest after increasing the...

Pettit, Krešimir Begović, Stjepan Mikac, Abdulla Dikku, Elvin Toromani, Momchil Panayotov, Tzvetan Zlatanov, Ovidiu Haruta, Sorin Dorog, Oleh Chaskovskyy, Martin Mikoláš, Pavel Janda, Michal Frankovič, Ruffy Rodrigo, Ondřej Vostarek, Michal Synek, Martin Dušátko, Tomáš Kníř, Daniel Kozák, Ondrej Kameniar, Radek Bače, Vojtěch Čada … & Miroslav Svoboda
AIMS We examined differences in lifespan among the dominant tree species (spruce (Picea abies (L.) H. Karst.), fir (Abies alba Mill.), beech (Fagus sylvatica L.), and maple (Acer pseudoplatanus L.)) across primary mountain forests of Europe. We ask how disturbance history, lifetime growth patterns, and environmental factors influence lifespan. LOCATIONS Balkan mountains, Carpathian mountains, Dinaric mountains. METHODS Annual ring widths from 20,600 cores from primary forests were used to estimate tree life spans, growth trends,...

Neil Coughlan, Eoghan Cunningham, Ross Cuthbert, Patrick Joyce, Pedro Anastacio, Filipe Banha, Nicolás Bonel, Stephanie Bradbeer, Elizabeta Briski, Vincent Butitta, Zuzana Čadková, Jaimie Dick, Karel Douda, Lawrence Eagling, Noé Ferreira-Rodríguez, Leandro Hünicken, Mattias Johansson, Louise Kregting, Anna Labecka, Deliang Li, Florencia Liquin, Jonathan Marescaux, Todd Morris, Patrycja Nowakowska, Małgorzata Ożgo … & Francisco Sylvester
1. Invasive bivalves continue to spread and negatively impact freshwater ecosystems worldwide. As different metrics for body size and biomass are frequently used within the literature to standardise bivalve related ecological impacts (e.g. respiration and filtration rates), the lack of broadly applicable conversion equations currently hinders reliable comparison across bivalve populations. To facilitate improved comparative assessment amongst studies originating from disparate geographic locations, we report body size and biomass conversion equations for six invasive freshwater...

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,...

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...

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....

Natural disturbance impacts on trade-offs and co-benefits of forest biodiversity and carbon

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...

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...

Data from: Direct and indirect effects of landscape and field management intensity on carabids through trophic resources and weeds

Benjamin Carbonne, David A. Bohan, Hana Foffovà, Eirini Daouti, Britta Frei, Veronika Neidel, Pavel Saska, Jiří Skuhrovec & Sandrine Petit
Carabids are important biological control agents of weeds and other pests in agricultural fields. The carabid community is built upon direct and indirect ecological effects of landscape complexity, field management intensity and biotic components that in interaction make any prediction of community size and composition challenging. We analyse a large-scale sample of 60 European cereal fields using Structural Equation Modelling to quantify the direct effects of field management intensity and the surrounding landscape, and their...
