Vegetation changes in urban grasslands over 25 years in the city of Zurich, Switzerland

Julia Kummli, Stefan Widmer, Markus Wilhelm, Jürgen Dengler & Regula Billeter
Many studies have demonstrated significant alterations in the species composition of grasslands in Central Europe over the past decades due to multiple drivers of anthropogenic environmental change. Most such studies deal with dry, acidic, wet or alpine grassland types, while little is known about changes in mesic grasslands, particularly in urban areas. To investigate the effects of anthropogenic environmental change on such grasslands, we resurveyed a selection of plots in the city of Zurich (Switzerland)...

Universität Bayreuth, Germany (1); Universität Bayreuth, Germany (2); Centrul de Ecologie Montană, România (3)

The CTC-Trail (“Coast-to-Carpathians”) is a conceptual educational geo-trail that is being created to guide visitors through a transect from the southern parts of the western Black Sea area grasslands through the steppe regions of Dobrogea and eastern Walachia to the young volcanoes of the Carpathian Mountains, highlighting aspects of natural and cultural importance along this route. The journey also spans...

Functional biogeography of Neotropical moist forests: trait-climate relationships and assembly patterns of tree communities

Bruno Pinho, Marcelo Tabarelli, Cajo Ter Braak, S. J. Wright, Victor Arroyo-Rodriguez, Maíra Benchimol, Bettina Engelbrecht, Simon Pierce, Peter Hietz, Bráulio Santos, Carlos Peres, Sandra Müller, Ian Wright, Frans Bongers, Madelon Lohbeck, Ülo Niinemets, Martijn Slot, Steven Jansen, Davi Jamelli, Renato Augusto Ferreira De Lima, Nathan Swenson, Richard Condit, Jos Barlow, Ferry Slik, Manuel Hernández-Ruedas … & Felipe Melo
Aim: Here we examine the functional profile of regional tree species pools across the latitudinal distribution of Neotropical moist forests, and test trait-climate relationships among local communities. We expected opportunistic strategies (acquisitive traits, small seeds) to be overrepresented in species pools further from the equator due to long-term instability, but also in terms of abundance in local communities in currently wetter, warmer and more seasonal climates. Location: Neotropics. Time period: Recent. Major taxa studied: Trees....

Allochthonous resources are less important for faunal communities on highly productive, small tropical islands

Sebastian Steibl, Robert Sigl, Sanja Blaha, Sophia Drescher, Gerhard Gebauer, Elif Gürkal, Frederic Hüftlein, Anna Satzger, Michael Schwarzer, Dimitri Seidenath, Jana Welfenbach, Raphael Zinser & Christian Laforsch
Ecosystems are interconnected by energy fluxes that provide resources for the inhabiting organisms along the transition zone. Especially where in-situ production is low, ecosystems can become highly dependent on external resources. The dependency on external input becomes less pronounced in systems with elevated in-situ production, where only consumer species close to the site of external input remain subsidized, whereas species distant to the input site rely on the in-situ production of the ecosystem. It is...

Data from: Middle Bronze Age land use practices in the north-western Alpine foreland – A multi-proxy study of colluvial deposits, archaeological features and peat bogs

Sascha Scherer, Benjamin Höpfer, Katleen Deckers, Elske Fischer, Markus Fuchs, Ellen Kandeler, Eva Lehndorff, Johanna Lomax, Sven Marhan, Elena Marinova, Julia Meister, Christian Poll, Humay Rahimova, Manfred Rösch, Kristen Wroth, Julia Zastrow, Thomas Knopf, Thomas Scholten & Peter Kühn
This paper aims to reconstruct Middle Bronze Age (MBA) land use practices in the north-western Alpine foreland (SW Germany, Hegau). We used a multi-proxy approach including the biogeochemical proxies from colluvial deposits in the surrounding of the well-documented settlement site of Anselfingen and offsite pollen data from two peat bogs. This approach allowed in-depth insights into the MBA subsistence economy and shows that the MBA in the north-western Alpine foreland was a period of establishing...

Data for: Spontaneous choices for insect-pollinated flower shapes by wild non-eusocial halictid bees

Scarlett Howard, Kit Prendergast, Matthew Symonds, Mani Shrestha & Adrian Dyer
The majority of angiosperms require animal pollination for reproduction and insects are the dominant group of animal pollinators. Bees are considered one of the most important and abundant insect pollinators. Research into bee behaviour and foraging decisions has typically centred on managed eusocial bee species, Apis mellifera and Bombus terrestris. Non-eusocial bees are understudied with respect to foraging strategies and decision-making, such as flower preferences. Understanding whether there are fundamental foraging strategies and preferences which...

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...

Primary data used to calculate predator-induced morphological changes in two Daphnia species-associated clones

Patricia Diel, Max Rabus & Christian Laforsch
The expression of inducible defences in reaction to an inconsistent predation pressure is especially well investigated in the freshwater keystone filter-feeder Daphnia. Out of their many inducible defences, which increase their fitness, the highest diversity of induced traits is found within their morphology. In recent time the focus of studies on these has switched, from the previously thoroughly covered large-scale defences, e.g., elongated/enlarged tail-spines, helmets and crests, to rather small-scale predator-induced changes. Inconspicuous spinules that...

Diversity patterns and community structure of the macrofauna along the beach-inland transition zone of small tropical islands: supporting raw data and code

Sebastian Steibl, Robert Sigl, Paul Eric Bräumer, Victoria Clauß, Simon Goddemeier, Stephan Hamisch, Darleen Lücker, Lisa Reiprich, Lucas Stegmann, Nora Voigt & Christian Laforsch
Biodiversity follows distinct and observable patterns. Where to systems meet, biodiversity is often increased, due to overlapping occurrence ranges and the presence of specialized species that can tolerate the dynamic conditions of the transition zones. One of the most pronounced transition zones occurs at shores, where oceans and terrestrial habitat collide, forming the shore-inland transition zone. The relevance of this transition zone in shaping a system’s community structure is particularly pronounced on small islands due...

Data from: Evolution of dispersal, habit, and pollination in Africa pushed Apocynaceae diversification after the Eocene-Oligocene climate transition

Nicolai M. Nürk, Cássia Bitencourt, Alessandro Rapini, Mark Fishbein, André O. Simões, David J. Middleton, Ulrich Meve, Mary E. Endress & Sigrid Liede-Schumann
Apocynaceae (the dogbane and milkweed family) is one of the ten largest flowering plant families, with approximately 5,350 species and diverse morphology and ecology, ranging from large trees and lianas that are emblematic of tropical rainforests, to herbs in temperate grasslands, to succulents in dry, open landscapes, and to vines in a wide variety of habitats. Despite a specialized and conservative basic floral architecture, Apocynaceae are hyperdiverse in flower size, corolla shape, and especially derived...

Opposing community assembly patterns for dominant and non-dominant plant species in herbaceous ecosystems globally

Carlos Alberto Arnillas, Elizabeth Borer, Eric Seabloom, Juan Alberti, Selene Baez, Jonathon Bakker, Elizabeth Boughton, Yvonne Buckley, Miguel Bugalho, Ian Donohue, John Dwyer, Jennifer Firn, Riley Gridzak, Nicole Hagenah, Yann Hautier, Aveliina Helm, Anke Jentsch, , Kimberly Komatsu, Lauri Laanisto, Ramesh Laungani, Rebecca McCulley, Joslin Moore, John Morgan, Pablo Peri … & Marc Cadotte
Biotic and abiotic factors interact with dominant plants —the locally most frequent or with the largest coverage— and non-dominant plants differently, partially because dominant plants modify the environment where non-dominant plants grow. For instance, if dominant plants compete strongly, they will deplete most resources, forcing non-dominant plants into a narrower niche space. Conversely, if dominant plants are constrained by the environment, they might not exhaust available resources but instead may ameliorate environmental stressors that usually...

Effects of different restoration treatments on long-term development of plant diversity and functional trait composition in calcareous grasslands

Stefan Hofmann, Timo Conradi, Kathrin Kiehl & Harald Albrecht
Establishment of calcareous grassland on ex-arable fields by introducing target species is one of the most frequently used methods to restore the species assemblages of this highly endangered habitat type. The present study evaluates the long-term success of calcareous grassland restoration on former arable land in the vicinity of one of the oldest nature reserves in Bavaria, the “Garchinger Heide”. The restoration experiment combined different measures like topsoil removal, transfer of freshly cut seed-containing hay...

Vegetation change in meso-xeric grasslands of the Swiss Jura Mts. over 40 years

Kévin Charmillot, Christian Hedinger, Manuel Babbi, Stefan Widmer & Jürgen Dengler
Meso-xeric grasslands have declined sharply in Central Europe during the last century. These species-rich habitats are threatened by intensification or abandonment of agricultural use, eutrophica-tion, climate change and landscape fragmentation. However, different studies in various regions of Central Europe are inconsistent in their findings about degree and direction of changes. We thus resurveyed the historical vegetation plots of the alliance Mesobromion in the Swiss Jura Mts. In 2020, we re-sampled 28 quasi-permanent vegetation plots originally...

Tourism and urban development as drivers for invertebrate diversity loss on tropical islands

Sebastian Steibl, Jonas Franke & Christian Laforsch
Oceanic islands harbour a disproportionately high number of endemic and threatened species. Rapidly growing human populations and tourism are posing an increasing threat to island biota, yet the ecological consequences of these human land uses on small oceanic island systems have not been quantified. Here, we investigated and compared the impact of tourism and urban island development on ground-associated invertebrate biodiversity and habitat composition on oceanic islands. To disentangle tourism and urban land uses, we...

Disentangling effects of climate and land use on biodiversity and ecosystem services – a multi-scale experimental design

Sarah Redlich, Jie Zhang, Caryl Benjamin, Maninder Singh Dhillon, Jana Englmeier, Jörg Ewald, Ute Fricke, Cristina Ganuza, Maria Hänsel, Thomas Hovestadt, Johannes Kollmann, Thomas Koellner, Carina Kübert-Flock, Harald Kunstmann, Annette Menzel, Christoph Moning, Wibke Peters, Rebekka Riebl, Thomas Rummler, Sandra Rojas Botero, Cynthia Tobisch, Johannes Uhler, Lars Uphus, Jörg Müller & Ingolf Steffan-Dewenter
1. Climate and land-use change are key drivers of environmental degradation in the Anthropocene, but too little is known about their interactive effects on biodiversity and ecosystem services. Long-term data on biodiversity trends are currently lacking. Furthermore, previous ecological studies have rarely considered climate and land use in a joint design, did not achieve variable independence or lost statistical power by not covering the full range of environmental gradients. 2. Here, we introduce a multi-scale...

Data from: Differences in sibling cooperation in presence and absence of parental care in a genus with interspecific variation in offspring dependence

Madlen Prang, Lena Zywucki, Maximilian Körner & Sandra Steiger
The widely spread evolutionary strategy of parental care is considered an important driver of social evolution. While offspring were long thought to primarily interact competitively, recent studies revealed the potential importance of sibling cooperation. Theories suggest that the degree of cooperation in offspring interactions depends on the degree of offspring dependence on parental care: offspring unable to forage on their own should compete more, whereas more independent juveniles may increase the degree of cooperation. In...

Changes in biodiversity and species composition of temperate beech forests in Switzerland over 26 years

Eline Staubli, Jürgen Dengler, Regula Billeter & Thomas Wohlgemuth
Ongoing climate warming affects vegetation in multiple ways, although it is difficult to distinguish its influence from other drivers of vegetation change. We studied how forest vegetation in the Albiskette (canton of Zurich, Switzerland), mainly dominated by European beech (Fagus sylvatica), changed from 1993 to 2019, while the mean temperature rose by 1.5 °C. To investigate how species richness and vegetation composition had changed during these 26 years, we resampled 46 permanently marked nested-plot series...

Human impact, climate and dispersal strategies determine plant invasion on islands

Severin D. H. Irl, Andreas H. Schweiger, Manuel J. Steinbauer, Claudine Ah-Peng, José R. Arévalo, Carl Beierkuhnlein, Alessandro Chiarucci, Curtis C. Daehler, José M. Fernández-Palacios, Olivier Flores, Christoph Kueffer, Petr Madera, Rüdiger Otto, Julienne M. I. Schweiger, Dominique Strasberg & Anke Jentsch
Aim: Biological invasions are likely determined by species dispersal strategies as well as environmental characteristics of a recipient region, especially climate and human impact. However, the contribution of climatic factors, human impact and dispersal strategies in driving invasion processes is still controversial and not well embedded in the existing theoretical considerations. Here, we study how climate, species dispersal strategies and human impact determine plant invasion processes on islands distributed in all major oceans in the...

Dataset for estimation of the biotic and climatic niche breadths and geographic range size of beech (Fagus) species worldwide

Qiong Cai, Erik Welk, Chengjun Ji, Wenjing Fang, Francesco Maria Sabatini, Jianxiao Zhu, Jiangling Zhu, Zhiyao Tang, Fabio Attorre, Juan Antonio Campos, Andraž Čarni, Milan Chytrý, Süleyman Çoban, Jürgen Dengler, Jiri Dolezal, Richard Field, József Pál Frink, Hamid Gholizadeh, Adrian Indreica, Ute Jandt, Dirk Nikolaus Karger, Jonathan Lenoir, Robert K. Peet, Remigiusz Pielech, Michele De Sanctis … & Helge Bruelheide
This dataset could be used to test whether the commonly observed positive range size–niche breadth relationship, as posited by the “niche breadth hypothesis”, exists for Fagus, one of the most dominant and widespread broad‐leaved deciduous tree genera in temperate forests of the Northern Hemisphere. There are many ways to estimate niche breadth. Here, we estimated biotic and climatic niche breadths per species using plot‐based co‐occurrence data and climate data, respectively. The range sizes of the...

Dispersal syndromes are poorly associated with climatic niche differences in the Azorean seed plants

María Leo, Manuel J. Steinbauer, Paulo A. V. Borges, Eduardo B. De Azevedo, Rosalina Gabriel, Hanno Schaefer & Ana M. C. Santos
Aim: Environmental niche tracking is linked to the species ability to disperse. While well investigated on large spatial scales, dispersal constraints also influence small-scale processes and may explain the difference between the potential and the realized niche of species at small-scales. Here we test whether niche size and niche fill differ systematically according to dispersal syndrome within isolated oceanic islands. We expect species with higher dispersal abilities (anemochorous or endozoochorous) will have a higher niche...

Variation of foliar silicon concentrations in temperate forbs: effects of soil silicon, phylogeny and habitat

Marius Klotz, Jörg Schaller, Susanne Kurze & Bettina MJ Engelbrecht
Silicon (Si) accumulation is known to alleviate various biotic and abiotic stressors in plants with potential ecological consequences. However, for dicotyledonous plants our understanding of Si variation remains limited. We conducted a comparative experimental study to investigate (1) interspecific variation of foliar Si concentrations across 37 dicotyledonous forbs of temperate grasslands, (2) intraspecific variation in foliar Si concentration in response to soil Si availability, the influence of (3) phylogenetic relatedness, and (4) habitat association to...
