Werner Härdtle, Erwin Bergmeier, Andreas Fichtner, Thilo Heinken, Norbert Hölzel, Dominique Remy, Simone Schneider, Angelika Schwabe, Sabine Tischew & Hartmut Dierschke
Hardwood floodplain forests (Ficario-Ulmetum, Syn.: Querco-Ulmetum), being amongst the most endangered plant communities in Germany, have been selected as ‘Plant community of the year 2021’ by the Floristisch-soziologische Arbeitsgemeinschaft. Hardwood floodplain forests are temperate low-land broad-leaved forest ecosystems typical of extensive river valleys. In Central Europe, stands represent biodiversity hotspots for woody species (as habitats for rare tree species such as Ulmus laevis and Populus nigra), but also host numerous fungi and animal species typical...

Female Assamese macaques bias their affiliation to paternal and maternal kin

Delphine De Moor, Christian Roos, Julia Ostner & Oliver Schülke
Forming strong social bonds can lead to higher reproductive success, increased longevity and/or increased infant survival in several mammal species. Given these adaptive benefits, understanding what determines partner preferences in social bonding is important. Maternal relatedness strongly predicts partner preference across many mammalian taxa. The role of paternal relatedness, however, has received relatively little attention, even though paternal and maternal kin share the same number of genes, and theoretically similar preferences would therefore be expected...

Fragmentation in trader preferences among multiple markets: Market coexistence versus single market dominance

Aleksandra Alorić, Robin Nicole & Peter Sollich
Technological advancement has lead to an increase in number and type of trading venues and diversification of goods traded. These changes have re-emphasized the importance of understanding the effects of market competition: does proliferation of trading venues and increased competition lead to dominance of a single market or coexistence of multiple markets? In this paper, we address these questions in a stylized model of Zero Intelligence traders who make repeated decisions at which of three...

Social contagion of affiliation in female macaques

Julia Ostner, Jana Wilken & Oliver Schülke
Social contagion of non-interactive behavior is widespread among animals including humans. It is thought to facilitate behavioral synchronization and consequently group cohesion, coordination, and opportunities for social learning. Contagion of interactive behavior - particularly affiliation - has received much less attention. Here, we investigated in female rhesus macaques (Macaca mulatta) the effect of observing group members groom on a subject’s subsequent grooming behavior and the potential modulation of contagion by relationship quality and social status....

Earthworm invasion causes declines across soil fauna size classes and biodiversity facets in northern North American forests

Malte Jochum, Olga Ferlian, Madhav Thakur, Marcel Ciobanu, Bernhard Klarner, Jörg-Alfred Salamon, Lee Frelich, Ed Johnson & Nico Eisenhauer
Anthropogenic pressures alter the biodiversity, structure, and organization of biological communities with severe consequences for ecosystem processes. Species invasion is such a human-induced ecosystem change with pronounced impacts on recipient ecosystems. Around the globe, earthworms invade habitats and impact abiotic soil conditions and a wide range of above- and belowground organisms. In northern North America, where earthworms have been largely absent since the last glaciation period and most earthworm species present today have only been...

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...

Microarthropod abundance data of a drought experiment comparing organic and conventional farming

Svenja Meyer
In Central Europe summer droughts are increasing in frequency which threatens production and biodiversity in agroecosystems. The potential of different farming systems to mitigate detrimental drought effects on soil animals is largely unknown. We investigated the effects of simulated drought on the abundance and community composition of soil microarthropods (Collembola, Oribatida, Meso­‑, Pro‑ and Astigmata) in winter wheat fields under long-term conventional and organic farming in the DOK trial, Switzerland. We simulated drought by excluding...

Mitificación de Pancho Villa: Un recorrido cultural y literario

Doris Wieser & Martha Grizel Delgado Rodríguez
pp. 109-126. In this essay we analyze the process of mythification of the hero of the Mexican Revolution, Pancho Villa, based on Jan Assmann’s (1992) theoretical approach to myth. First, we summarize the "official myth" created by the political discourse, answering the following questions: who transformed Pancho Villa into a myth, how did they do it and for what purposes? We will apply the concepts of Assmann, who distinguishes between "cold" and "hot" memories. We...

Conversion of Andean montane forests into plantations: effects on soil characteristics, microorganisms and microarthropods

Franca Marian, Pablo Ramirez Castillo, Carlos Iñiguez Armijos, Sven Günter, Mark Maraun & Stefan Scheu
Tropical montane forests in the Andes are subjected to deforestation and subsequent transformation into pastures. Abandoned pastures are frequently reforested by planting monoculture timber plantations, resulting in reduced aboveground diversity and changes in soil characteristics compared to primary forests. In this study, we evaluated differences in soil properties (litter layer thickness, pH, water content and C-to-N ratio) between degraded primary montane forest and monoculture pine (Pinus patula) and alder (Alnus acuminata) plantations and their effect...

Vascular epiphyte global distributions

Amanda Taylor, Gerhard Zotz, Patrick Weigelt, Lirong Cai, Dirk Karger, Christian König & Holger Kreft
Aim: Vascular epiphytes are ubiquitous components of wet tropical forests where they contribute substantially to local and regional plant diversity. While some basic epiphyte distribution patterns are relatively well studied, little effort has been made to understand the drivers responsible for constraining their global distribution. This study quantifies the substantial contribution of epiphytes to global gradients and centres of vascular plant diversity and explores whether epiphytes vary from terrestrial plants in relation to contemporary and...

Data from: Functional diversity and redundancy of tropical forests shift with elevation and forest-use intensity

María Leticia Monge González, Nathaly Guerrero Ramírez, Thorsten Krömer, Holger Kreft & Dylan Craven
1. Change and intensification of forest use alter tropical ecosystems, influencing biodiversity and, subsequently, ecosystem functioning. The implications of eroding biodiversity may go beyond decreases in species diversity, resulting in changes of functional diversity, i.e. the diversity of ecological strategies present in the community, and functional redundancy, i.e. how redundant these strategies are to biodiversity loss. However, how environmental conditions and anthropogenic influences shape functional diversity and redundancy in tropical forests remains poorly understood. 2....

Pacific Introduced Flora (PacIFLora)

Michael Wohlwend, Dylan Craven, Patrick Weigelt, Hanno Seebens, Marten Winter, Holger Kreft, Wayne Dawson, Franz Essl, Mark Van Kleunen, Jan Pergl, Petr Pyšek, James Space, Philip Thomas & Tiffany Knight
The Pacific region has the highest density of naturalized plant species worldwide, which makes it an important area for research on the ecology, evolution and biogeography of biological invasions. While different data sources on naturalized plant species exist for the Pacific, there is no taxonomically and spatially harmonized database available for different subsets of species and islands. A comprehensive, accessible database containing the distribution of naturalized vascular plant species in the Pacific will enable new...

Data from: Traits mediate niches and co-occurrences of forest beetles in ways that differ among bioclimatic regions

Ryan C. Burner, Jörg G. Stephan, Lukas Drag, Tone Birkemoe, Jörg Muller, Tord Snäll, Otso Ovaskainen, Mária Potterf, Juha Siitonen, Olav Skarpaas, Inken Doerfler, Martin M. Gossner, Peter Schall, Wolfgang W. Weisser & Anne Sverdrup-Thygeson
Aim To investigate the role of traits in beetle community assembly and test for consistency in these effects among several bioclimatic regions. We asked (1) whether traits predicted species’ responses to environmental gradients (i.e., their niches), (2) whether these same traits could predict co-occurrence patterns, and (3) how consistent were niches and the role of traits among study regions. Location Boreal forests in Norway and Finland, temperate forests in Germany. Methods We complied capture records...

Data from: Integrated SDM database: Enhancing the relevance and utility of species distribution models in conservation management

Veronica F. Frans, Amélie A. Augé, Jim Fyfe, Yuqian Zhang, Nathan McNally, Hendrik A. Edelhoff, Niko Balkenhol & Jan O. Engler
1. Species’ ranges are changing at accelerating rates. Species distribution models (SDMs) are powerful tools that help rangers and decision-makers prepare for reintroductions, range shifts, reductions, and/or expansions by predicting habitat suitability across landscapes. Yet, range-expanding or -shifting species in particular face other challenges that traditional SDM procedures cannot quantify, due to large differences between a species’ currently-occupied range and potential future range. The realism of SDMs is thus lost and not as useful for...

Unexpected cryptic species among streptophyte algae most distant to land plants

Iker Irisarri, Tatyana Darienko, Thomas Pröschold, Janine M. R. Fürst-Jansen, Mahwash Jamy & Jan De Vries
Streptophytes are one of the major groups of the green lineage (Chloroplastida or Viridiplantae). During one-billion-years of evolution, streptophytes have radiated into an astounding diversity of uni- and multicellular green algae as well as land plants. Most divergent from land plants is a clade formed by Mesostigmatophyceae, Spirotaenia spp., and Chlorokybophyceae. All three lineages are species-poor and the Chlorokybophyceae consist of a single described species, Chlorokybus atmophyticus. In this study, we used phylogenomic analyses to...

Data from: The role of the introduced rusa deer Cervus timorensis for wildlife hunting in West Papua, Indonesia

Margaretha Pangau-Adam, Marlina Flassy, Jan-Niklas Trei, Matthias Waltert & Mahmood Soofi
The rusa deer has been introduced to Merauke region and later to Vogelkop Peninsula in Indonesian New Guinea (West Papua) in 1928. It has widely dispersed across much of the West Papuan lowlands, but little is known on population size and its role for the livelihoods of rural communities. Here, our aim was to assess the population status of rusa deer, and to investigate the extent of hunting practices on this mammal in West Papua....

Mineral nitrogen nutrition of Fagus sylvatica L roots colonized by ectomycorrhizal fungi in native forest soil

Carmen Alicia Rivera Pérez, Dennis Janz, Dominik Schneider, Rolf Daniel & Andrea Polle
The aim of this study was to examine the transcription-level response of a symbiotic system comformed by the host tree Fagus sylvatica L (European beech) and the root-associated mycobiota to fluctuations in ammonium and nitrate availability in the soil. The experiment was conducted with young trees grown at a natural regeneration forest. We used 15N stable isotopes in combination with DNA-based and RNA-based molecular methods and Illumina sequencing. We report data on the beech root-associated...

Semi-open landscapes of former military training areas are key habitats for threatened birds

Heike Culmsee, Boris Evers, Tobias Leikauf & Karsten Wesche
Military training areas (MTAs) show high numbers of rare and threatened species and diverse habitat patterns due to low nitrogen input and heterogeneous disturbance dynamics caused by mili-tary training activities that produce fine-scale landscape mosaics. Since the 1990s, major parts of MTAs in Europe have been decommissioned. In Germany, most of them were transferred to the national natural heritage now facing the challenge of developing comprehensive conservation man-agement strategies. In order to elucidate their current...

Dynamik und Konstanz zweier Orchideen-Arten in der Ackerbrachen-Sukzession und im Kalk-Buchenwald – Cephalanthera damasonium (Mill.) Druce undEpipactis helleborine (L.) Crantz

Wolfgang Schmidt
The evaluation of long-term vegetation data on the occurrence of Cephalanthera damasonium and Epipactis helleborine has two objectives: (i) To identify site conditions that allow orchids to colonize new habitats, and (ii) to identify long- or short-term changes in the abundance of orchids, which can be correlated with environmental factors. For the first objective the following methods and results were employed: In a succession experiment running since 1969 on a former arable field in the...

Die Vegetation Deutschlands – eine vergleichende Übersicht der Klassen, Ordnungen und Verbände auf Grundlage der EuroVegChecklist

Erwin Bergmeier
The EuroVegChecklist (MUCINA et al. 2016) is a reference catalogue of the European vegetation. It provides a synopsis of hierarchical vegetation classes, orders and alliances which can be used as a tool towards standardization of other syntaxonomic surveys and concepts. The present paper cross-references the EuroVegChecklist to six regional and national influential works on the vegetation of Germany with different syntaxonomic concepts. It provides an update of the vegetation diversity of the country and some...

Agent‐based modeling of the effects of forest dynamics, selective logging, and fragment size on epiphyte communities

Gunnar Petter, Gerhard Zotz, Holger Kreft & Juliano Sarmento Cabral
Forest canopies play a crucial role in structuring communities of vascular epiphytes by providing substrate for colonization, by locally varying microclimate, and by causing epiphyte mortality due to branch or tree fall. However, as field studies in the three-dimensional habitat of epiphytes are generally challenging, our understanding of how forest structure and dynamics influence the structure and dynamics of epiphyte communities is scarce. Mechanistic models can improve our understanding of epiphyte community dynamics. We present...
