Data from: Genetic barcoding of dark-spored myxomycetes (Amoebozoa)—Identification, evaluation and application of a sequence similarity threshold for species differentiation in NGS studiesMathilde Borg Dahl, Asker D. Brjenrod, Martin Unterseher, Thomas Hoppe, Yun Feng, Yuri Novozhilov, Søren J. Sørensen, Martin Schnittler & Asker D. Brejnrod
Unicellular, eukaryotic organisms (protists) play a key role in soil food webs as major predators of microorganisms. However, due to the polyphyletic nature of protists, no single universal barcode can be established for this group, and the structure of many protistean communities remains unresolved. Plasmodial slime moulds (Myxogastria or Myxomycetes) stand out among protists by their formation of fruit bodies, which allow for a morphological species concept. By Sanger sequencing of a large collection of...
Data from: Male spiders reduce pre- and postmating sexual investment in response to sperm competition riskCristina Tuni, Sabrina Weber, Trine Bilde & Gabriele Uhl
The interplay between pre- and post-mating responses to intra-sexual competition remains enigmatic. Sperm competition models often assume a trade-off between pre- and post-mating traits that enhance mate acquisition and fertilization success, respectively. However, when males court females through food donations (i.e. nuptial gifts), pre- and post-mating responses may be aligned, as nuptial gifts have the dual function of facilitating both mate acquisition and sperm transfer. In the spider Pisaura mirabilis nuptial gifts consist of silk-wrapped...
Data from: Trait variation in response to varying winter temperatures, diversity patterns and signatures of selection along the latitudinal distribution of the widespread grassland plant Arrhenatherum elatiusStefan G. Michalski, Andrey V. Malyshev & Juergen Kreyling
Across Europe, genetic diversity can be expected to decline toward the North because of stochastic and selective effects which may imply diminished phenotypic variation and less potential for future genetic adaptations to environmental change. Understanding such latitudinal patterns can aid provenance selection for breeding or assisted migration approaches. In an experiment simulating different winter temperatures, we assessed quantitative trait variation, genetic diversity, and differentiation for natural populations of the grass Arrhenatherum elatius originating from a...
Data from: Indirect genetic effects and sexual conflicts: Partner genotype influences multiple morphological and behavioural reproductive traits in a flatwormLucas Marie-Orleach, Nadja Vogt-Burri, Pierick Mouginot, Aline Schlatter, Dita B. Vizoso, Nathan W. Bailey & Lukas Schärer
The expression of an individual's phenotypic traits can be influenced by genes expressed in its social partners. Theoretical models predict that such indirect genetic effects (IGEs) on reproductive traits should play an important role in determining the evolutionary outcome of sexual conflict. However, empirical tests of (i) whether reproductive IGEs exist, (ii) how they vary among genotypes, and (iii) whether they are uniform for different types of reproductive traits are largely lacking. We addressed this...
Increasing heat stress caused by anthropogenic climate change may pose a substantial challenge to biodiversity due to associated detrimental effects on survival and reproduction. Therefore, heat tolerance has recently received substantial attention, but its variation throughout ontogeny and effects carried over from one developmental stage to another remained largely neglected. To explore to what extent stress experienced early in life affects later life stages, we here investigate effects of heat stress experienced in the egg...
The recently discovered insect order Mantophasmatodea currently comprises 19 Southern African species. These mainly occur in allopatry, have high levels of colour polymorphism and communicate via species- and gender-specific vibratory signals. High levels of interspecific morphological conservatism mean that cryptic species are likely to be uncovered. These aspects of Mantophasmatodean biology make them an ideal group in which to investigate population divergence due to habitat-specific adaptation, sexual selection and potentially sensory speciation. Lack of appropriate...
Data from: Effects of temperature and drought on early life stages in three species of butterflies: mortality of early life stages as a key determinant of vulnerability to climate change?Michael Klockmann & Klaus Fischer
Anthropogenic climate change poses substantial challenges to biodiversity conservation. Well-documented responses include phenological and range shifts, and declines in cold but increases in warm-adapted species. Thus, some species will suffer while others will benefit from ongoing change, although the biological features determining the prospects of a given species under climate change are largely unknown. By comparing three related butterfly species of different vulnerability to climate change, we show that stress tolerance during early development may...
