Scale dependency of joint species distribution models challenges interpretation of biotic interactions

Christian König, Rafael O. Wüest, Catherine H. Graham, Dirk Nikolaus Karger, Thomas Sattler, Niklaus E. Zimmermann & Damaris Zurell
Aim: Separating the biotic and abiotic factors controlling species distributions has been a long-standing challenge in ecology and biogeography. Joint species distribution models (JSDMs) have emerged as a promising statistical framework towards this objective by simultaneously modeling the environmental responses of multiple species and approximating species associations based on patterns in their (co-)occurrences. However, the signature of biotic interactions should be most evident at fine spatial resolutions. Here, we test how the resolution of input...

Phenotypic plasticity versus ecotypic differentiation under recurrent summer drought in two drought-tolerant pine species

Christoph Bachofen, Anouchka Perret-Gentil, Tom Wohlgemuth, Pierre Vollenweider & Barbara Moser
1. Despite worldwide reports of high tree mortality, growing evidence indicates that many tree species are well adapted to survive repeated dry spells. The drought resilience of trees is related to their phenotypic plasticity and ecotypic differentiation. Whether these two mechanisms act at the same organisational level of a tree and involve similar plant traits is still unknown. 2. We assessed phenotypic plasticity and ecotypic differentiation across four populations of Pinus sylvestris and Pinus nigra...

Seasonal and annual dynamics of litterfall

Cunguo Wang, Xingbo Zheng, Anzhi Wang, Guanhua Dai, Baokun Zhu, Yueming Zhao, Shijie Dong, Weizhong Zu, Wei Wang, Yiguo Zheng & Mai-He Li
Long-term data of litterfall can indicate overall forest functions in forest ecosystems. We collected monthly (May – October) and annual (1981 – 2018) litterfall including leaves, twigs, bark, reproductive and miscellaneous fractions in a mixed mature Pinus koraiensis forest on Changbai Mountain in Northeast, China, across 30 years. Based on these long-term litterfall data, we analyzed the seasonal and annual variations in different litterfall fractions and their relationships with climatic factors. Climate data were obtained...

ANDEAN frugivory: data on plant–bird interactions and functional traits of plant and bird species from montane forests along the Andes

D. Matthias Dehling, Irene M. A. Bender, Pedro G. Blendinger, Marcia C. Muñoz, Marta Quitián, Francisco Saavedra, Vinicio Santillán, Katrin Böhning-Gaese, Eike-Lena Neuschulz & Matthias Schleuning
Species differ in their resource use and their interactions with other species and, consequently, they fulfil different functional roles in ecological processes. Species with specialized functional roles (specialists) are considered important for communities because they often interact with species with which few other species interact, thereby contributing complementary functional roles to ecological processes. However, the contribution of specialists could be low if they only interact with a small range of interaction partners. In contrast, species...

Data from: Declines in occurrence of plants characteristic for a nutrient-poor meadow habitat are partly explained by their responses to nutrient addition and competition

Stefanie Höckendorff, Markus Peintinger, Felicitas Fiedler, Marc Stift & Mark Van Kleunen
Species losses and local extinctions are alarmingly common, frequently as a consequence of habitat destruction. Nevertheless, many intact habitats also face species losses, most likely due to environmental changes. However, the exact drivers, and why they affect some species more than others in apparently intact habitats, are still poorly understood. Addressing these questions requires data on changes in occurrence frequency of many species, and comparisons of the responses of those species to experimental manipulations of...

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,...

Data from: Fine-scale spatial genetic structure across the species range reflects recent colonization of high elevation habitats in silver fir (Abies alba Mill.)

Enikő I. Major, Mária Höhn, Camilla Avanzi, Bruno Fady, Katrin Heer, Lars Opgenoorth, Andrea Piotti, Flaviu Popescu, Dragos Postolache, Giovanni G. Vendramin & Katalin Csilléry
Variation in genetic diversity across species ranges has long been recognized as highly informative for assessing populations’ resilience and adaptive potential. The spatial distribution of genetic diversity within populations, referred to as fine-scale spatial genetic structure (FSGS), also carries information about recent demographic changes, yet it has rarely been connected to range scale processes. We studied eight silver fir (Abies alba Mill.) population pairs (sites), growing at high and low elevations, representative of the main...

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...

Data from: Thermal differences between juveniles and adults increased over time in European forest trees

Maria Mercedes Caron, Florian Zellweger, Kris Verheyen, Lander Baeten, Radim Hédl, Bernhardt-Römermann Markus, Imre Berki, Jörg Brunet, Guillaume Decocq, Sandra Díaz, Thomas Dirnböck, Tomasz Durak, Thilo Heinken, Bogdan Jaroszewicz, Martin Kopecký, Jonathan Lenoir, Martin Macek, Malicki Marek, František Máliš, Thomas Nagel, Michael Perring, Petr Petřík, Kamila Reczyńska, Remigiusz Pielech, Wolfgang Schmidt … & Pieter De Frenne
Woody species’ requirements and environmental sensitivity change from seedlings to adults, a process referred to as ontogenetic shift. Such shifts can be increased by climate change. To assess the changes in the difference of temperature experienced by seedlings and adults in the context of climate change, it is essential to have reliable climatic data over long periods that capture the thermal conditions experienced by the individuals throughout their life cycle. Here we used a unique...

Both diversity and functional composition affect productivity and water use efficiency in experimental temperate grasslands

Charlotte Grossiord, Manuel Walde, Eric Allan, Seraina L. Cappelli, Margaux Didion‐Gency, Arthur Gessler, Marco M. Lehmann & Noémie A. Pichon
Many experiments have shown that biodiversity promotes ecosystem functioning and stability and that this relationship varies with resource availability. However, we still have a poor understanding of the underlying physiological and ecological mechanisms driving diversity effects and how they may interact with soil nutrient availability. We collected data in a grassland experiment factorially manipulating fertilization, species richness, functional composition (slow-growing vs. fast-growing species), and functional diversity in resource economic traits. We measured aboveground productivity, nitrogen...

Data from: Postglacial determinants of regional species pools in alpine grasslands

Borja Jiménez-Alfaro, Wolfgang Willner, Eszter Ruprecht, Kiril Vassilev, Nevena Kuzmanovic, Renata Ćušterevska, Djordjije Milanovic, Josef Sibik, Sylvain Abdulhak, Angela Stanisci, Maria Luisa Carranza, Ariel Bergamini, Corrado Marcenó & Gianpietro Giusso Del Galdo
Aim: Alpine habitats support unique biodiversity confined to high-elevation areas in the current interglacial. Plant diversity in these habitats responds to area, environment, connectivity and isolation, yet these factors have been rarely evaluated in concert. Here we investigate major determinants of regional species pools in alpine grasslands, and the responses of their constituent species groups. Location: European mountains below 50ºN. Time Period: Between 1928 and 2019. Major Taxa Studied: Vascular plants. Methods: We compiled species...

Interactive effects of tree species mixture and climate on foliar and woody trait variation in a widely distributed deciduous tree

Margaux Didion-Gency
Despite increasing reports of severe drought and heat impacts on forest ecosystems, community-level processes, which could potentially modulate tree responses to climatic stress, are rarely accounted for. While numerous studies indicate a positive effect of species diversity on a wide range of ecosystem functions and services, little is known about how species interactions influence tree responses to climatic variability. We quantified the intraspecific variation in 16 leaf and wood physiological, morphological, and anatomical traits in...

Jakob Pavlin, Thomas A. Nagel, Marek Svitok, Joseph L. 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,...

Trait-habitat associations explain novel bird assemblages mixing native and alien species across New-Zealand landscapes

Jean-Yves Barnagaud, Eckehard Brockerhoff, Raphael Mossion, Paul Dufour, Sandrine Pavoine, Marc Deconchat & Luc Barbaro
Aim: Species introductions have reshaped island faunas for the last 200 years, often threatening native biodiversity. Approximately equal numbers of native and alien species currently co-occur in the New Zealand avifauna, but they show distinct habitat use. Antagonistic interactions, habitat affinities and legacies of introduction history may concur to explain their segregation along habitat gradients. To investigate these processes, we explored how habitat, ecological traits and introduction history relate with the current composition of bird...

Long term irrigation experiment

Arun Bose, Andreas Rigling, Arthur Gessler, Frank Hagedorn, Ivano Brunner, Linda Feichtinger, Christof Bigler, Simon Egli, Sophia Etzold, Martin Gossner, Claudia Guidi, Mathieu Lévesque, Katrin Meusburger, Martina Peter, Matthias Saurer, Daniel Scherrer, Patrick Schleppi, Leonie Schönbeck, Michael Vogel, Georg Von Arx, Beat Wermelinger, Thomas Wohlgemuth, Roman Zweifel & Marcus Schaub
Climate change exposes ecosystems to strong and rapid changes in their environmental boundary conditions mainly due to the altered temperature and precipitation patterns. It is still poorly understood how fast interlinked ecosystem processes respond to altered environmental conditions, if these responses occur gradually or suddenly when thresholds are exceeded, and if the patterns of the responses will reach a stable state. We conducted an irrigation experiment in the Pfynwald, Switzerland from 2003-2018. A naturally dry...

Data from: National assessments of species vulnerability to climate change strongly depend on selected data sources

Daniel Scherrer, Manuel Esperon-Rodriguez, Linda J. Beaumont, Victor L. Barradas & Antoine Guisan
Aim: Correlative species distribution models (SDMs) are among the most frequently used tools for conservation planning under climate and land-use changes. Conservation-focused climate change studies are often conducted on a national or local level and can use different sources of occurrence records (e.g., local databases, national biodiversity monitoring) collated at different geographic extents. However, little is known about how these restrictions in geographic space (i.e., Wallacean shortfall) can lead to restrictions in environmental space (i.e....

Size-selective exclusion of mammals and invertebrates differently affects grassland plant communities depending on vegetation type

Xiaowei Wang, Martin Schutz & Anita Risch
Human-caused loss of vertebrate and invertebrate animals, defaunation, is increasing, and potentially affects plant community structure of diverse grassland ecosystems worldwide. We experimentally simulated defaunation using size-selective fences to progressively exclude large-, medium- and small-sized mammals, and invertebrates from two subalpine vegetation types in the Swiss National Park (SNP): intensively grazed short-grass and moderately grazed tall-grass vegetation. We assessed plant community properties yearly from 2009 to 2013, and examined treatment effects on plant community structure...

Regeneration biomass (AGB & BGB), age, NSCs and light: F. sylvatica and Acer spp.

Petrovska Petrovska
Being able to persist in deep shade is an important characteristic of juvenile trees often leading to a strong dominance of shade-tolerant species in forests with low canopy turnover and disturbance rate. While leaf, growth and storage traits are known to be key components of shade tolerance, their interplay during regeneration development and influence on juveniles’ survival time remains unclear. We assessed the ontogenetic effects of these three traits on survival time of beech (Fagus...

Global maps of current (1979-2013) and future (2061-2080) habitat suitability probability for 1,485 European endemic plant species

Robin Pouteau, Idoia Biurrun, Caroline Brunel, Milan Chytrý, Wayne Dawson, Franz Essl, Trevor Fristoe, Rense Haveman, Carsten Hobohm, Florian Jansen, Holger Kreft, Jonathan Lenoir, Bernd Lenzner, Carsten Meyer, Jesper Erenskjold Moeslund, Jan Pergl, Petr Pyšek, Jens-Christian Svenning, Wilfried Thuiller, Patrick Weigelt, Thomas Wohlgemuth, Qiang Yang & Mark Van Kleunen
Aims: The rapid increase in the number of species that have naturalized beyond their native range is among the most apparent features of the Anthropocene. How alien species will respond to other processes of future global changes is an emerging concern and remains largely misunderstood. We therefore ask whether naturalized species will respond to climate and land-use change differently than those species not yet naturalized anywhere in the world. Location: Global Methods: We investigated future...

Environmental DNA metabarcoding to monitor tropical reef fishes in Providencia island

Camille Albouy, Polanco Andrea & Pellissier Loïc
Environmental DNA (eDNA) provides a revolutionary method to monitor species in marine ecosystems from animal DNA present in the water. Examining the capacity of eDNA to provide accurate biodiversity measures in species-rich ecosystems such as coral reefs is a prerequisite for their long-term monitoring. Here, we surveyed a Colombian tropical marine reefs, Providencia Island using eDNA method. We collected a large quantity of surface water (30 L per filter) above the reefs and applied a...

Ecological interactions shape the evolution of flower colour in communities across a temperate biodiversity hotspot

Alexander Skeels, Russell Dinnage, Iliana Medina & Marcel Cardillo
Processes driving the divergence of floral traits may be integral to the extraordinary richness of flowering plants and the assembly of diverse plant communities. Several models of pollinator-mediated floral evolution have been proposed; floral divergence may (i) be directly involved in driving speciation or may occur after speciation driven by (ii) drift or local adaptation in allopatry or (iii) negative interactions between species in sympatry. Here, we generate predictions for patterns of trait divergence and...
