Recent climate and land-use changes are having substantial impacts on biodiversity, including population declines, range shifts, and changes in community composition. However, few studies have compared these impacts among multiple taxa, particularly because of a lack of standardized time series data over long periods. Existing datasets are typically of low resolution or poor coverage, both spatially and temporally, thereby limiting the inferences that can be drawn from such studies. Here, we compare climate and land-use...

Long-term (1901-2017) phenology data of 20 forest understory herbs in Europe, collected from herbaria and GBIF, used in: \"Forest wildflowers bloom earlier as Europe warms: Lessons from herbaria and spatial modeling\", New Phytologist

Franziska Merle Willems
Today plants often flower earlier due to climate warming, and the collection dates of herbarium specimens can provide proof of this.
To test for such fingerprints of climate change in Europe, we compiled a long-term (1901-2017) dataset from 6131 herbarium specimens of 20 early-flowering European forest understory herbs. The data were collected in the herbaria of Jena (JE), Stuttgart (STU) and Tübingen (TUB), and were complemented with herbarium data from the database GBIF.
The final data file...

Amazonian epiphytic bryophytes: community matrix and tools to assess diversity across scales

Monica Bibiana Berdugo Moreno, S. Robbert Gradstein, Louise Guérot, Susana León-Yánez, Jörg Bendix & Maaike Bader
Aim: Tropical forests are highly diverse at many spatial scales. In these forests, epiphytic bryophyte communities can be species-rich already within a few cm2, and their species numbers increase when expanding the sampling along the tree and the forest. Understanding how this diversity increase depends on scale and position within the tree is critical to evaluate the processes that maintain biodiversity. We, therefore, studied vertical zonation and alpha and beta diversity of epiphytic bryophytes across...

Dataset: Cool birds: First evidence of energy-saving nocturnal torpor in free-living common swifts Apus apus resting in their nests

Arndt H. J. Wellbrock, Luca R. H. Eckhardt, Natalie A. Kelsey, Gerhard Heldmaier, Jan Rozman & Klaudia Witte
Daily torpor is a means of saving energy by controlled lowering of the metabolic rate (MR) during resting, usually coupled with a decrease in body temperature. We studied nocturnal daily torpor under natural conditions in free-living common swifts Apus apus resting in their nests as a family using two non-invasive approaches. First, we monitored nest temperature (Tnest) in up to 50 occupied nests per breeding season in 2010-2015. Drops in Tnest were the first indication...

Fungal fruit body assemblages are tougher in harsh microclimates

Franz-Sebastian Krah, Jonas Hagge, Jasper Schreiber, Roland Brandl, Jörg Müller & Claus Bässler
Forest species are affected by macroclimate, however, the microclimatic variability can be more extreme and change through climate change. Fungal fruiting community composition was affected by microclimatic differences. Here we ask whether differences in the fruiting community can be explained by morphological traits of the fruit body, which may help endure harsh conditions. We used a dead wood experiment and macrofungal fruit body size, color, and toughness. We exposed logs of two host tree species...

Data from: Forest degradation limits the complementarity and quality of animal seed dispersal

Finn Rehling, Jan Schlautmann, Bogdan Jaroszewicz, Dana G. Schabo & Nina Farwig
Forest degradation changes the structural heterogeneity of forests and species communities, with potential consequences for ecosystem functions including seed dispersal by frugivorous animals. While the quantity of seed dispersal may be robust towards forest degradation, changes in the effectiveness of seed dispersal through qualitative changes are poorly understood. Here, we carried out extensive field sampling on the structure of forest microhabitats, seed deposition sites, and plant recruitment along three characteristics of forest microhabitats (canopy cover,...

Catering to the Patient

Miriam Urff, Antonio Krüger, Steffen Ruchholtz & Eva C. Stibane
Introduction: It has been shown that communication skills acquired during undergraduate medical education are of great importance. Hence, many countries require teaching communication as part of their medical curricula. To assess students’ learning progress, “Catering to the Patient”, as an aspect of showing empathy, should be evaluated. Since there was no description of a validated instrument fitting for this purpose, one had to be developed. To describe its process of development and its psychometric properties...

Climate warming changes synchrony of plants and pollinators

Jonas Freimuth, Oliver Bossdorf, J.F. Scheepens & Franziska Willems
Climate warming changes the phenology of many species. When interacting organisms respond differently, climate change may disrupt their interactions and affect the stability of ecosystems. Here, we used GBIF occurrence records to examine phenology trends in plants and their associated insect pollinators in Germany since the 1980s. We found strong phenological advances in plants, but differences in the extent of shifts among pollinator groups. The temporal trends in plant and insect phenologies were generally associated...

Trait functional diversity explains mixture effects on litter decomposition at the arid end of a climate gradient

Rafaella Canessa, Liesbeth Van Den Brink, Monica Berdugo, Stephan Hattenschwiler, Rodrigo Rios, Alfredo Saldana, Katja Tielboerger & Maaike Bader
Litter decomposition is controlled by climate, litter quality and decomposer communities. Because the decomposition of specific litter types is also influenced by the properties of adjacent types, mixing litter types may result in non-additive effects on overall decomposition rates. The strength of these effects seems to depend on the litter functional diversity. However, it is unclear which functional traits or combination of traits explain litter mixture effects and if these depend on the range of...
