Trait-based analyses explaining the different responses of species and communities to environmental changes are increasing in frequency. European butterflies are an indicator group that responds rapidly to environmental changes with extensive citizen science contributions to documenting changes of abundance and distribution. Species traits have been used to explain long- and short-term responses to climate, land-use and vegetation changes. Studies are often characterised by limited traits sets being used, with risks that the relative roles of...
Assigning occurrence data to cryptic taxa improves climatic niche assessments: biodecrypt, a new tool tested on European butterfliesLeonardo Dapporto, Platania Leonardo, Mattia Menchetti, Cecília Corbella, Isaac Kay-Lavelle, Roger Vila, Martin Wiemers & Oliver Schweiger
Aim Occurrence data are fundamental to macroecology, but accuracy is often compromised when multiple units are lumped together (e.g. in recently separated cryptic species or citizen science records). Using amalgamated data leads to inaccuracy in species mapping, to biased beta-diversity assessments and to potentially erroneously predicted responses to climate change. We provide a set of R functions (biodecrypt) to objectively attribute undetermined occurrences to the most probable taxon based on a subset of identified records....
The dataset includes abundance data from xylobiont beetles, captured in the Leipzig floodplain forest between March and October 2016. We sampled three strata and three tree species. The strata were the understory with 2 traps, the lower canopy with 12 traps and the upper canopy with 12 traps. The 24 traps in the lower and upper canopy can further be assigned to the tree species Quercus robur, Tilia cordata and Fraxinus excelsior. Each tree was...
Data from: Life-history dimensions indicate non-random assembly processes in tropical island tree communitiesJulian Schrader, Dylan Craven, Cornelia Sattler, Rodrigo Cámara-Leret, Soetjipto Moeljono & Holger Kreft
Community assembly processes on islands are often non-random. The mechanisms behind non-random assembly, however, are generally difficult to disentangle. Functional diversity in combination with a null model approach that accounts for differences in species richness among islands can be used to test for non-random assembly processes, but has been applied rarely to island communities. By linking functional diversity of trees on islands with a null model approach, we bridge this gap and test for the...
Data from: Abundance, origin and phylogeny of plants do not predict community-level patterns of pathogen diversity and infectionRobin Schmidt, Harald Auge, Holger Deising, Isabell Hensen, Scott Mangan, Martin Schädler, Claudia Stein & Tiffany Knight
Pathogens have the potential to shape plant community structure, and thus it is important to understand the factors that determine pathogen diversity and infection in communities. The abundance, origin and evolutionary relationships of plant hosts are all known to influence pathogen patterns, and are typically studied separately. We present an observational study that examined the influence of all three factors and their interactions on the diversity of and infection of several broad taxonomic groups of...
Seasonal succession of functional traits in phytoplankton communities and their interaction with trophic stateValerie Wentzky, Jörg Tittel, Christoph Jäger, Jorn Bruggeman & Karsten Rinke
1. Understanding and explaining the structure of communities in response to environmental gradients is a central goal in ecology. Trait-based approaches are promising but yet rarely applied to understand community dynamics in response to changing environmental conditions. 2. Here we investigate seasonal succession patterns of functional traits in phytoplankton communities and how nutrient reductions (oligotrophication) alter these patterns. We used phytoplankton data from 40 years of observation from the Rappbode Reservoir (Germany), which underwent a...
Data from: Movement and seasonal energetics mediate vulnerability to disturbance in marine mammal populationsCara Gallagher, Volker Grimm, Line Kyhn, Carl Kinze & Jacob Nabe-Nielsen
In marine environments noise from human activities is increasing dramatically, causing animals to alter their behavior and forage less efficiently. These alterations incur energetic costs that can result in reproductive failure, death, and may ultimately influence population viability; yet the link between population dynamics and individual energetics is poorly understood. We present an energy budget model for simulating effects of acoustic disturbance on populations. It accounts for environmental variability and individual state, while incorporating realistic...
Dominant native and non-native graminoids differ in key leaf traits irrespective of nutrient availabilityArthur Broadbent, Jennifer Firn, James McGree, Elizabeth Borer, Yvonne Buckley, W. Stanley Harpole, Kimberly Komatsu, Andrew MacDougall, Kate Orwin, Nicholas Ostle, Eric Seabloom, Jonathan Bakker, Lori Biedermann, Maria Caldeira, Nico Eisenhauer, Nicole Hagenah, Yann Hautier, Joslin Moore, Carla Nogueira, Pablo Peri, Anita Risch, Christiane Roscher, Martin Schuetz & Carly Stevens
Aim Nutrient enrichment is associated with plant invasions and biodiversity loss. Functional trait advantages may predict the ascendancy of invasive plants following nutrient enrichment but this is rarely tested. Here, we investigate 1) whether dominant native and non-native plants differ in important morphological and physiological leaf traits, 2) how their traits respond to nutrient addition, and 3) whether responses are consistent across functional groups. Location Australia, Europe, North America and South Africa Time period 2007...
Trade-off between vegetation type, soil erosion control and surface water in global semi-arid regions: A meta-analysisGao-Lin Wu, Yi-Fan Liu, Zeng Cui, Yu Liu, Zhi-Hua Shi, Rui Yin & Paul Kardol
Soil erosion control and water resource protection can closely interact during restoration of terrestrial ecosystems. In semi‐arid ecosystems, an urgent issue is how vegetation restoration can achieve the goal of soil erosion mitigation and water conservation, which in turn, feeds back to ecosystem functioning. We reviewed 78 articles from 22 countries in semi‐arid areas to evaluate the effects of vegetation type (i.e. forest, grassland and scrubland) on runoff and sediment yields across different environmental conditions...
Data from: Microclimate limits thermal behaviour favourable to disease control in a nocturnal amphibianWouter Beukema, Frank Pasmans, Sarah Van Praet, Francisco Ferri-Yáñez, Moira Kelly, Alexandra Laking, Jesse Erens, Jeroen Speybroeck, Kris Verheyen, Luc Lens & An Martel
While epizootics increasingly affect wildlife, it remains poorly understood how the environment shapes most host-pathogen systems. Here, we employ a three-step framework to study microclimate influence on ectotherm host thermal behaviour, focusing on amphibian chytridiomycosis in fire salamanders (Salamandra salamandra) infected with the fungal pathogen Batrachochytrium salamandrivorans (Bsal). Laboratory trials reveal that innate variation in thermal preference, rather than behavioural fever, can inhibit infection and facilitate salamander recovery under humidity-saturated conditions. Yet, a three-year field...
