Arthropod (per year, 2008-2017) and environmental data (climate, land use, land cover) from grasslands used in \"Unravelling insect declines: can space replace time?\", Biology Letters

Michael Staab & Nico Blüthgen
To compare trends in arthropod species numbers between space and time, arthropod data from the sweep net samples (2008-2017) in grasslands were used. We tested whether trends over time are also found within single years (i.e. in space). The dataset contains, pooled per sampling year, arthropod individual numbers (Araneae, Coleoptera, Hemiptera, Orthoptera) and associated environmental data (climate, land use, land cover). This data is only to complement the publication "Unravelling insect declines: can space replace...

Hydrothermal conditions determine soil potential net N mineralization rates in arid and semi-arid grasslands

Shuya Hu, Changhui Wang, Anita Risch, Yuan Liu, Yang Li, Lei Li, Xiaohui Xu, Nianpeng He, Xingguo Han & Jianhui Huang
Soil net nitrogen (N) mineralization is a key biogeochemical process influencing plant available N and net primary productivity (NPP) in terrestrial ecosystems. However, the spatial variations and controlling factors of soil net N mineralization (RPNM) in arid and semi-arid grasslands are less studied and unclear. In this study, we investigated the soil RPNM by performing a laboratory incubation experiment. Soil samples were collected from 30 sites in three east-west transects on the Inner Mongolia Plateau...

Lucas P. Martins, Daniel B. Stouffer, Pedro G. Blendinger, Katrin Böhning-Gaese, Galo Buitrón-Jurado, Marta Correia, José Miguel Costa, D. Matthias Dehling, Camila I. Donatti, Carine Emer, Mauro Galetti, Ruben Heleno, Pedro Jordano, Ícaro Menezes, José Carlos Morante-Filho, Marcia C. Muñoz, Eike Lena Neuschulz, Marco Aurélio Pizo, Marta Quitián, Roman A. Ruggera, Francisco Saavedra, Vinicio Santillán, Virginia Sanz D’Angelo, Matthias Schleuning, Luís Pascoal Da Silva … & Jason M. Tylianakis
Species interactions can propagate disturbances across space via direct and indirect effects, potentially connecting species at a global scale. However, ecological and biogeographic boundaries may mitigate this spread by demarcating the limits of ecological networks. We tested whether large-scale ecological boundaries (ecoregions and biomes) and human disturbance gradients increase dissimilarity among plant-frugivore networks, while accounting for background spatial and elevational gradients and differences in network sampling. We assessed network dissimilarity patterns over a broad spatial...

Impact of warmer and drier conditions on tree photosynthetic properties and the role of species interactions

Margaux Didion-Gency
Increased temperature and prolonged soil moisture reduction have distinct impacts on tree photosynthetic properties. Yet, our knowledge of their combined effect is limited. Moreover, how species interactions alter photosynthetic responses to warming and moisture reduction remains unclear. Using mesocosms, we studied how photosynthetic properties of European beech and downy oak were impacted by multi-year warming and moisture reduction alone or combined, and how species interactions (intra- vs. interspecific interactions) modulated these effects. Warming of +5°C...

Plant community impact on productivity: trait diversity or key(stone) species effects?

Philipp Brun, Cyrille Violle, David Mouillot, Nicolas Mouquet, Brian Enquist, François Munoz, Tamara Munkemuller, Annette Ostling, Niklaus Zimmermann & Wilfried Thuiller
Outside controlled experimental plots, the impact of community attributes on primary productivity has rarely been compared to that of individual species. Here, we identified plant species of high importance for productivity (key species) in >29,000 diverse grassland communities in the European Alps, and compared their effects with those of community-level measures of functional composition (weighted means, variances, skewness, and kurtosis). After accounting for the environment, the five most important key species jointly explained more deviance...

Global invasion history of the emerging plant pathogen Phytophthora multivora

Tetyana Tsykun, Simone Prospero, Corine N. Schoebel, Alexander Rea & Treena I. Burgess
Abstract Background: global trade in living plants and plant material has significantly increased the geographic distribution of many plant pathogens. As a consequence, several pathogens have been first found and described in their introduced range where they may cause severe damage on naïve host species. Knowing the center of origin and the pathways of spread of a pathogen is of importance for several reasons, including identifying natural enemies and reducing further spread. Several Phytophthora species...

Rebuilding green infrastructure in boreal production forest given future global wood demand

Helen Moor, Jeannette Eggers, Henna Fabritius & Tord Snäll
Global policy for future biodiversity conservation is ultimately implemented at landscape and local scales. In parallel, green infrastructure (GI) planning needs to account for socio-economic dynamics at national and global scales. Progress towards policy goals must, in turn, be evaluated at the landscape scale. Evaluation tools are often environmental quality objectives (EQO) indicators. We present three management scenarios for a 100,000 hectare boreal forest landscape in Sweden in the coming 100 years. The scenarios optimize...

Ecuadorian Plant-Hummingbird interactions over an elevation gradient in the Andes, sampled with camera traps in 11 localities

François Duchenne
Community ecologists have made great advances in understanding how natural communities can be both diverse and stable by studying communities as interaction networks. However, focus has been on interaction networks aggregated over time, neglecting the consequences of the seasonal organization of interactions, henceforth seasonal structure, for community stability. Here, we extended previous theoretical findings on the topic in two ways: (i) by integrating empirical seasonal structure of 11 plant-hummingbird communities into dynamic models, and (ii)...

Heintzman, Owen Wangensteen, Willy Tinner, Fabian Rey, Martina Lia Heer, Astrid Rutzer, Kevin Walsh, Youri Lammers, Antony G. Brown, Tomasz Goslar, Dilli P. Rijal, Dirk N. Karger, Loïc Pellissier, Group PhyloAlps Consortium, Oliver Heiri & Inger Greve Alsos
The European Alps are highly rich in species, but their future may be threatened by ongoing changes in human land use and climate. Here, we reconstructed vegetation, temperature, human impact and livestock over the past ~12,000 years from Lake Sulsseewli, based on sedimentary ancient plant and mammal DNA, pollen, spores, chironomids, and microcharcoal. We assembled a highly-complete local DNA reference library (PhyloAlps, 3,923 plant taxa), and used this to obtain an exceptionally rich sedaDNA record...

Avian seed dispersal may be insufficient for plants to track future temperature change on tropical mountains

Larissa Nowak, Matthias Schleuning, Irene M. A. Bender, Katrin Böhning-Gaese, D. Matthias Dehling, Susanne A. Fritz, W. Daniel Kissling, Thomas Mueller, Eike Lena Neuschulz, Alex L. Pigot, Marjorie C. Sorensen & Isabel Donoso
Abstract Aim: Climate change causes species’ range shifts globally. Terrestrial plant species often lag behind temperature shifts, and it is unclear to what extent animal-dispersed plants can track climate change. Here, we estimate the ability of bird-dispersed plant species to track future temperature change on a tropical mountain. Location: Tropical elevational gradient (500–3500 m a.s.l.) in the Manú biosphere reserve, Peru Time period: 1960–1990 to 2061–2080 Taxa: Fleshy-fruited plants, avian frugivores Methods: Using simulations based...

Number of growth days and not length of the growth period determines radial stem growth of temperate trees

Sophia Etzold, Frank Sterck, Arun Bose, Sabine Braun, Nina Buchmann, Werner Eugster, Arthur Gessler, Ansgar Kahmen, Richard Peters, Lorenz Walthert, Yann Vitasse, Kasia Zieminska, Haeni Matthias, Micah Wilhelm, Volodymyr Trotsiuk & Zweifel Roman
Radial stem growth dynamics at seasonal resolution are essential to understand how forests respond to climate change. We studied daily radial growth of 160 individuals of seven temperate tree species at 47 sites across Switzerland over eight years. Growth of all species peaked in the early part of the growth season and commenced shortly before the summer solstice, but with species-specific seasonal patterns. Day length set a window of opportunity for radial growth. Within this...

Warming may extend tree growing seasons and compensate for reduced carbon uptake during dry periods

Charlotte Grossiord, Christoph Bachofen, Jonas Gisler, Eugenie Mas, Yann Vitasse & Margaux Didion-Gency
1. Warming and drought alter plant phenology, photosynthesis and growth with important consequences for the global carbon cycle and the earth’s climate. Yet, few studies have attempted to tease apart their effects on tree phenology, particularly leaf senescence, and on source and sink activity. 2. We experimentally assessed the single and combined effects of warming and reduced soil moisture on the phenology (leaf-out and senescence date, growing season length) and aboveground sink (height and diameter...

Describing woody plant traits - Woody Plant Ontology

Inês Chaves, Célia Michotey, Christel Anger,, Véronique Jorge, François Ehrenmann, Frédéric Jean, Lars Opgenoorth & Célia Miguel
Woody plants lateral meristems lead to extensive production of secondary growth tissues (wood/secondary xylem and cork/phellem). As a result, a set of characteristic traits related to secondary tissues can be described in these plants. Woody Plant Ontology describes variables applied during woody plant observations. This ontology covers several domains of knowledge in woody plant biology, from the agronomic down to the biochemical level, with the goal of standardizing and organizing trait information. This will facilitate...

Data from: Genetic divergence along a climate gradient shapes chemical plasticity of a foundation tree species to both changing climate and herbivore damage

Michael Eisenring, Rebecca J. Best, Mark R. Zierden, Hillary F. Cooper, Madelyn Norstrem, Thomas G. Whitham, Kevin Grady, Gerard J. Allan & Richard L. Lindroth
Climate change is threatening the persistence of many tree species via independent and interactive effects on abiotic and biotic conditions. In addition, changes in temperature, precipitation, and insect attacks can alter the traits of these trees, disrupting communities and ecosystems. For foundation species such as Populus, phytochemical traits are key mechanisms linking trees with their environment and are likely jointly determined by interactive effects of genetic divergence and variable environments throughout their geographic range. Using...

Moths and butterflies on alien shores – global biogeography of non-native Lepidoptera

Richard Mally, Rebecca M. Turner, Rachael E. Blake, Gyda Fenn-Moltu, Cleo Bertelsmeier, Eckehard G. Brockerhoff, Robert J. B. Hoare, Helen F. Nahrung, Alain Roques, Deepa S. Pureswaran, Takehiko Yamanaka & Andrew M. Liebhold
Lepidoptera is a highly diverse, predominantly herbivorous insect order, with species transported to outside their native range largely facilitated by the global trade of plants and plant-based goods. Analogous to island disharmony, we examine invasion disharmony, where species filtering during invasions increases systematic compositional differences between native and non-native species assemblages, and test whether some families are more successful at establishing in non-native regions than others. We compared numbers of non-native, unintentionally introduced Lepidoptera species...

Population genetics and biogeography of the lungwort lichen in North America support distinct Eastern and Western gene pools

Jessica Allen, R. Troy McMullin, Yolanda F. Wiersma & Christoph Scheidegger
Populations of species with large spatial distributions are shaped by complex forces that differ throughout their ranges. To maintain the genetic diversity of species, genepool-based subsets of widespread species must be considered in conservation assessments. In this study, the population genetics of the lichenized fungus Lobaria pulmonaria and its algal partner, Symbiochloris reticulata , were investigated to determine population structure, genetic diversity, and degree of congruency in eastern and western North America. Data loggers measuring...

Tree mixtures increase bird taxonomic and functional diversity over pure stands of tree species planted outside their natural range—but not over pure native stands

Andreas Schuldt, Pelle Huke, Jonas Glatthorn, Jonas Hagge, Benjamin Wildermuth & Dragan Matevski
Recent biodiversity loss has emphasized the necessity to critically evaluate the consequences of human alterations of forest ecosystems. Stand diversification via tree species mixtures and the use of non-native tree species are two such alterations currently gaining importance as climate change adaptations. However, the effects of local versus regional tree mixing on associated biodiversity and notably the modifying role of tree species growing outside their natural range remain poorly understood. We assessed how monocultures and...

The role of diversity, body size and climate in dung removal: a correlative and experimental approach

Friederike Gebert, Ingolf Steffan-Dewenter, Patrick Kronbach & Marcell Peters
The mechanisms by which climatic changes influence ecosystem functions, i.e. by a direct climatic control of ecosystem processes or by modifying richness and trait compositions of species communities, remain unresolved. This study is a contribution to this discourse by elucidating the linkages between climate, land use, biodiversity, body size and ecosystem functions. We disentangled direct climatic from biodiversity-mediated effects by using dung removal by dung beetles as a model system and by combining correlative field...

Synthesis reveals that island species-area relationships emerge from processes beyond passive sampling

Leana Gooriah, Shane Blowes, Alban Sagouis, Julian Schrader, Dirk Karger, Holger Kreft & Jon Chase
Aim The Island Species-Area Relationship (ISAR) quantifies how the number of species increases as the area of an island or island-like habitat gets larger, and is one of ecology’s most general patterns. However, studies that measure the ISAR often confound variation in sampling methodology and analyses, precluding appropriate syntheses of its underlying mechanisms. While most ISAR studies only use presence-absence data at the whole-island scale, we aggregated data sets of species-level abundances allowing for individual-based...

No risk – no fun: Penalty and recovery from spring frost damages in deciduous temperate trees

Frederik Baumgarten, Arthur Gessler & Yann Vitasse
Phenological shifts in response to changing climatic conditions are a key acclimation process for the persistence of perennial plants in temperate and boreal climates. The optimal time to leaf-out is the result of evolutionary processes determined by the trade-off between minimizing the risk of freezing damages and herbivory pressure while maximizing resource uptake to increase competitiveness against the other plants. We quantified the penalty exerted by frost exposure at the time of leaf emergence on...
