Plant intraspecific functional trait variation is related to within-habitat heterogeneity and genetic diversity in Trifolium montanum L.

Kevin Karbstein, Kathleen Prinz, Frank Hellwig & Christine Römermann
Intraspecific trait variation (ITV), based on available genetic diversity, is one of the major means plant populations can respond to environmental variability. The study of functional trait variation and diversity has become popular in ecological research, e.g. as a proxy for plant performance influencing fitness. Up to now, it is unclear which aspects of intraspecific functional trait variation (iFDCV) can be attributed to the environment or genetics under natural conditions. Here, we examined 260 individuals...

Data from: Trophic level and basal resource use of soil animals are hardly affected by local plant associations in abandoned arable land

Jörg-Alfred Salamon, Janet Wissuwa, Stefan Scheu, Anton Potapov & Thomas Frank
Stable isotope composition of plants and soil animals in abandoned arable land Dataset provides raw data on stable isotope composition of C and N of plants and soil meso- and macrofauna. Dominating animal groups were collected in arable fallow systems 3 and 14-16 years after abandonment. Animals were sampled from the rhizosphere of three plant species of different functional groups: a legume (Medicaco sativa), a non-legume herb (Taraxacum officinale) and a grass (Bromus sterilis). More...

Data from: Studded leather collars are very effective in protecting cattle from leopard (Panthera pardus) attacks

Igor Khorozyan, Siavash Ghoddousi, Mobin Soufi, Mahmood Soofi & Matthias Waltert
Human-wildlife conflicts are widespread, particularly with big cats which can kill domestic livestock and create a counteraction between conservation and local livelihoods, especially near protected areas. Minimization of livestock losses caused by big cats and other predators is essential to mitigate conflicts and promote socially acceptable conservation. As big cats usually kill by throat bites, protective collars represent a potentially effective non-lethal intervention to prevent livestock depredation, yet the application and effectiveness estimation of these...

Eumelanin and pheomelanin pigmentation in mollusc shells may be less common than expected: insights from mass spectrometry

Susanne Affenzeller, Klaus Wolkenstein, Holm Frauendorf & Daniel Jackson
Background: The geometric patterns that adorn the shells of many phylogenetically disparate molluscan species are comprised of pigments that span the visible spectrum. Although early chemical studies implicated melanin as a commonly employed pigment, surprisingly little evidence generated with more recent and sensitive techniques exists to support these observations. Results: Here we present the first mass spectrometric investigations for the presence of eumelanin and pheomelanin in 13 different molluscan species from three conchiferan classes: Bivalvia,...

Data from: Biocultural approaches to sustainability: a systematic review of the scientific literature

Jan Hanspach, L. Jamila Haider, Elisa Oteris-Rozas, Anton Stahl Olafsson, Natalie Gulsrud, Chris Raymond, Mario Torralba, Berta Martín-López, Claudia Bieling, María García Martín, Christian Albert, Thomas Beery, Nora Fagerholm, Isabel Díaz-Reviriego, Annika Drews-Shambroom & Tobias Plieninger
Current sustainability challenges demand approaches that acknowledge a plurality of human-nature interactions and worldviews, for which biocultural approaches are considered appropriate and timely. This systematic review analyses the application of biocultural approaches to sustainability in scientific journal articles published between 1990 and 2018 through a mixed methods approach combining qualitative content analysis and quantitative multivariate methods. The study identifies seven distinct biocultural lenses, i.e. different ways of understanding and applying biocultural approaches, which to different...

Data from: Soils from cold and snowy temperate deciduous forests release more nitrogen and phosphorus after soil freeze–thaw cycles than soils from warmer, snow-poor conditions

Juergen Kreyling, Rhena Schumann & Robert Weigel
Effects of global warming are most pronounced in winter. A reduction in snow cover due to warmer atmospheric temperature in formerly cold ecosystems, however, could counteract an increase in soil temperature by reduction of insulation. Thus, soil freeze-thaw cycles (FTC) might increase in frequency and magnitude with warming, potentially leading to a disturbance of the soil biota and release of nutrients. Here, we assessed how soil freeze-thaw magnitude and frequency affect short-term release of nutrients...

Bonds of bros and brothers: Kinship and social bonding in post-dispersal male macaques

Delphine De Moor, Christian Roos, Julia Ostner & Oliver Schülke
Group-living animals often maintain a few very close affiliative relationships – social bonds – that can buffer them against many of the inevitable costs of gregariousness. Kinship plays a central role in the development of such social bonds. The bulk of research on kin biases in sociality has focused on philopatric females, who typically live in deeply kin-structured systems, with matrilineal dominance rank inheritance and life-long familiarity between kin. Closely related males, in contrast, are...

Data from: Life-history dimensions indicate non-random assembly processes in tropical island tree communities

Julian 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...

Do infants and preschoolers quantify probabilities based on proportions?

Sarah Placì, Julia Fischer & Hannes Rakoczy
Most statistical problems encountered throughout life require the ability to quantify probabilities based on proportions. Recent findings on the early ontogeny of this ability have been mixed: For example, when presented with jars containing preferred and less preferred items, 12-month-olds, but not 3- and 4-years-olds, seem to rely on the proportions of objects in the jars to predict the content of samples randomly drawn out of them. Given these contrasting findings, it remains unclear what...

The smell of cooperation: rats increase helpful behaviour when receiving odour cues of a conspecific performing a cooperative task

Nina Gerber, Manon Schweinfurth & Michael Taborsky
Reciprocity can explain cooperative behaviour among non-kin, where individuals help others depending on their experience in previous interactions. Norway rats (Rattus norvegicus) cooperate reciprocally according to direct and generalized reciprocity. In a sequence of four consecutive experiments, we show that odour cues from a cooperating conspecific are sufficient to induce altruistic help of rats in a food-exchange task. When rats were enabled to help a non-cooperative partner while receiving olfactory information from a rat helping...

Data from: Crop pollination services: complementary resource use by social vs solitary bees facing crops with contrasting flower supply

Svenja Bänsch, Teja Tscharntke, Doreen Gabriel & Catrin Westphal
1. Many farmers are facing high economic risks if pollinator declines continue or temporal and spatial variation in wild bee communities cause reduced pollination services. Co-flowering crops might compete for pollinators, while they also might facilitate the delivery of pollination services. This rarely studied topic is of particular interest with respect to the foraging decisions of bees from different functional groups and when more sparsely and mass-flowering crops are in bloom at the same time....

Around the world in 10 million years: rapid dispersal of a kleptoparasitoid spider wasp (Pompilidae: Ceropales)

Juanita Rodriguez, Sarah Bank, Cecilia Waichert, Carol Von Dohlen & James Pitts
Aim: Our aim was to estimate the historical biogeography of the kleptoparasitoid genus Ceropales and to determine the processes leading to its current worldwide distribution. We tested hypotheses of dispersal and vicariance scenarios underlying its widespread distribution. Location: Worldwide. Methods: Data from two nuclear markers (the D2–D3 regions of the 28S ribosomal RNA and long-wavelength rhodopsin) and one mitochondrial marker (cytochrome c oxidase I) for 52 specimens of Ceropales were used to reconstruct a dated...

New insights into tree architecture from mobile laser scanning and geometry analysis

Dominik Seidel, Yonten Dorji, Bernhard Schuldt, Emilie Isasa & Klaus Körber
The structure and dynamics of a forest are defined by the architecture and growth patterns of its individual trees. In turn, tree architecture and growth result from the interplay between the genetic building plans and environmental factors. We set out to investigate whether (i) latitudinal adaptations of the crown shape occur due to characteristic solar elevation angles at a species’ origin, (ii) architectural differences in trees are related to seed dispersal strategies, and (iii) tree...
