Changes in salt marsh detritivore identity influences on ecosystem multifunctionality

Jes Hines
Ecosystems world-wide experience changes in species composition in response to natural and anthropogenic changes in environmental conditions. Research to date has greatly improved our understanding of how species affect focal ecosystem functions. However, because measurements of multiple ecosystem functions have not been consistently justified for any given trophic group, it is unclear whether interpretations of research syntheses adequately reflect the contributions of consumers to ecosystems. Using model communities assembled in experimental microcosms, we examined the...

Data from: Tree species rather than type of mycorrhizal association drives inorganic and organic nitrogen acquisition in tree-tree interactions

Judy Simon, Robert Reuter, Olga Ferlian, Mika Tarkka, Nico Eisenhauer & Karin Pritsch
A field study was conducted to evaluate the effects of associated mycorrhization type on tree-tree interactions using the framework of the MyDiv tree diversity experiment established at the Bad Lauchstädt Experimental Research Station of the Helmholtz Centre for Environmental Research (UFZ) (Saxony-Anhalt, Germany). Inorganic and organic net N uptake capacity was quantified in fine roots of AM (i.e. Acer pseudoplatanus L., Fraxinus excelsior L., and Prunus avium L.) as well as EM associated tree species...

Vulnerability of grassland seed banks to resource-enhancing global changes

Anu Eskelinen, Elise Elwood, Susan Harrison, Eva Beyen & Jennifer Gremer
Soil seed banks represent reservoirs of diversity in the soil that may increase resilience of communities to global changes. Two global change factors that can dramatically alter the composition and diversity of aboveground communities are nutrient enrichment and increased rainfall. In a full-factorial nutrient and rainfall addition experiment in an annual Californian grassland, we asked whether shifts in aboveground composition and diversity were reflected in belowground seed banks. Nutrient and rainfall additions increased exotic and...

Effects of large herbivores on fire regimes and wildfire mitigation

Julia Rouet-Leduc, Guy Pe'er, Francisco Moreira, Aletta Bonn, Wouter Helmer, S. Alain Aidan Shahsavan Zadeh, Alexander Zizka & Fons Van Der Plas
1. Abandonment of agricultural land is widespread in many parts of the world, leading to shrub and tree encroachment. The increase of flammable plant biomass, i.e. fuel load, increases the risk and intensity of wildfires. Fuel reduction by herbivores is a promising management strategy to avoid fuel build-up and mitigate wildfires. However, their effectiveness in mitigating wildfire damage may depend on a range of factors, including herbivore type, population density and feeding patterns. 2. Here...

Data for: Environmental and anthropogenic constraints on animal space use drive extinction risk worldwide

Myriam R. Hirt, Andrew D. Barnes, Alessandro Gentile, Laura J. Pollock, Benjamin Rosenbaum, Wilfried Thuiller, Marlee A. Tucker & Ulrich Brose
Animals require a certain amount of habitat to persist and thrive, and habitat loss is one of the most critical drivers of global biodiversity decline. While habitat requirements have been predicted by relationships between species traits and home range size, little is known about constraints imposed by environmental conditions and human impacts on a global scale. Our meta-analysis of 395 vertebrate species shows that global climate gradients in temperature and precipitation exert indirect effects via...

In the eye of the beholder: Is color classification consistent amongst human observers?

Kim Valenta, Sally Bornbusch, Yan-Daniel Jacques & Omer Nevo
Colorful displays have evolved in multiple plant and animal species as signals to mutualists, antagonists, competitors, mates, and other potential receivers. Studies of color have long relied on subjective classifications of color by human observers. However, humans have a limited ability to perceive color compared to other animals, and human biological, cultural, and environmental variables can influence color perception. Here, we test the consistency of human color classification using fruit color as a model system....

Agriculture causes homogenization of plant-feeding nematode communities at the regional scale

Antonio Archidona-Yuste, Thorsten Wiegand, Nico Eisenhauer, Carolina Cantalapiedra-Navarrete, Juan E. Palomares-Rius & Pablo Castillo
1. An emerging research line in conservation ecology addresses how environmental change drivers may cause the biotic homogenization of ecological communities by shifts in species diversity and community composition. While the drivers have been explored in unmanaged ecosystems and managed agricultural systems, this issue has received limited attention in regards to a key soil bioindicator organisms, soil nematodes. 2. In this study, we evaluated the effect of land-use change and intensification on the diversity of...

Plant history and soil history jointly influence the selection environment for plant species in a long-term grassland biodiversity experiment

Peter Dietrich, Nico Eisenhauer, Peter Otto & Christiane Roscher
Long-term biodiversity experiments have shown increasing strengths of biodiversity effects on plant productivity over time. However, little is known about rapid evolutionary processes in response to plant community diversity, which could contribute to explaining the strengthening positive relationship. To address this issue, we performed a transplant experiment with offspring of seeds collected from four grass species in a 14-year old biodiversity experiment (Jena Experiment). We used two- and six-species communities and removed the vegetation of...

Invasive spread in meta-food-webs depends on landscape structure, fertilization and species characteristics

Johanna Häussler, Remo Ryser & Ulrich Brose
Land use change and biological invasions collectively threaten biodiversity. Yet, few studies have addressed how altering the landscape structure and nutrient supply can promote biological invasions and particularly invasive spread (the spread of an invader from the place of introduction), or asked whether and how these factors interact with biotic interactions and invader properties. We here bridge this knowledge gap by providing a holistic network-based approach. Our approach combines a trophic network model with a...

Floristic changes of xerothermic grasslands in Central Germany: A resurvey study based on quasi-permanent plots

Tim Meier, Isabell Hensen & Monika Partzsch
Biodiversity has declined in the dry and semi-dry grasslands of Central Germany over the past three decades, mainly as a result of ‘Global Change’, including changes to traditional land use prac-tices. Such processes have promoted the spread of grass species such as Bromus erectus, which has become increasingly dominant within xerothermic grasslands. The aim of the study was to investi-gate changes in the vegetation of such grasslands over the last two decades by comparing previous...

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...

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)...

Determination of habitat requirements of the glacial relict Nuphar pumila as basis for successful (re-)introductions

Sabrina Keller, Manuel Babbi, Stefan Widmer, Jamyra Gehler, Sonja Hausmann, Christian Berg, Flavia Landucci, Patrick Schwager, Kateřina Šumberová & Jürgen Dengler
Nuphar pumilais a glacial relict, which is nowadays rare throughout Europe and red-listed in most European regions. In Switzerland only three autochthonous populations and one population of the hybrid with N. lutea (N. ×spenneriana) have survived to date, one of them in the canton of Zurich. To protect this species regionally, the canton of Zurich has commissioned the ex situ propagation of speci-mens, which then had been introduced to 37 water bodies in protected areas,...

Fitness and fur colouration - testing the camouflage and thermoregulation hypotheses in an Arctic mammal

Cecilia Di Bernardi, Anne-Mathilde Thierry, Nina E. Eide, Diana E. Bowler, Lars Rød-Eriksen, Stefan Blumentrath, Lukas Tietgen, Brett Sandercock, Øystein Flagstad & Arild Landa
1. Selection for crypsis has been recognised as an important ecological driver of animal coloration, whereas the relative importance of thermoregulation is more contentious with mixed empirical support. A potential thermal advantage of darker individuals has been observed in a wide range of animal species. Arctic animals that exhibit colour polymorphisms and undergo seasonal colour moults are interesting study subjects for testing the two alternative hypotheses: demographic performance of different colour morphs might be differentially...

Environmental controls on butterfly occurrence and species richness in Israel: The importance of temperature over rainfall

Orr Comay, Oz Ben Yehuda, Racheli Schwartz-Tzachor, Dubi Benyamini, Israel Pe'er, Inbar Ktalav & Guy Pe’er
Aim Butterflies are considered important indicators representing the state of biodiversity and key ecosystem functions, but their use as bioindicators requires better understanding of how their observed response link to environmental factors. Moreover, better understanding how butterfly faunas vary with climate and land cover may be useful to estimate the potential impacts of various drivers, including climate change, botanical succession, grazing, and afforestation. It is particularly important to establish which species of butterflies are sensitive...

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...

Fruit hardness, size, and weight for wild fruits in Uganda and Madagascar

Kim Valenta & Omer Nevo
Fleshy fruits have evolved to be attractive to frugivorous seed dispersers. As a result, many fruit traits like size, color, scent and nutritional content are assumed to be the result of selective pressures exerted by frugivores. At the same time, fruit traits are also subjected to a set of other selective pressures and constraints. One such trait is fruit hardness. On one hand, haptic cues have been suggested to play a role in frugivore behavior,...

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...

Expert-based assessment of rewilding indicates progress at site-level, yet challenges for upscaling

Josiane Segar, Henrique Pereira, Raquel Filgueiras, Alexandros Karamanlidis, Deli Saavedra & Néstor Fernández
Rewilding is gaining importance across Europe, as agricultural abandonment trajectories provide opportunities for large-scale ecosystem restoration. However, its effective implementation is hitherto limited, in part due to a lack of monitoring of rewilding interventions and their interactions. Here, we provide a first assessment of rewilding progress across seven European sites. Using an iterative and participatory Delphi technique to standardize and analyze expert-based knowledge of these sites, we 1) map rewilding interventions onto the three central...

Date From: The myriad of complex demographic responses of terrestrial mammals to climate change and gaps of knowledge: A global analysis

Maria Paniw, Tamora James, C. Ruth Archer, Gesa Römer, Sam Levin, Aldo Compagnoni, Judy Che-Castaldo, Joanne Bennett, Andrew Mooney, Dylan Childs, Arpat Ozgul, Owen Jones, Jean Burns, Andrew Beckerman, Abir Patwari, Nora Sanchez-Gassen, Tiffany Knight & Roberto Salguero-Gómez
Approximately 25% of mammals are currently threatened with extinction, a risk that is amplified under climate change. Species persistence under climate change is determined by the combined effects of climatic factors on multiple demographic rates (survival, development, reproduction), and hence, population dynamics. Thus, to quantify which species and regions on Earth are most vulnerable to climate-driven extinction, a global understanding of how different demographic rates respond to climate is urgently needed. Here, we perform a...

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...
