Data from: Comparative evaluation of potential indicators and temporal sampling protocols for monitoring genetic erosion

Sean Hoban, Jan A. Arntzen, Michael W. Bruford, José A. Godoy, A. Rus Hoelzel, Gernot Segelbacher, Carles Vilà & Giorgio Bertorelle
Genetic biodiversity contributes to individual fitness, species' evolutionary potential, and ecosystem stability. Temporal monitoring of the genetic status and trends of wild populations' genetic diversity can provide vital data to inform policy decisions and management actions. However, there is a lack of knowledge regarding which genetic metrics, temporal sampling protocols, and genetic markers are sufficiently sensitive and robust, on conservation-relevant timescales. Here, we tested six genetic metrics and various sampling protocols (number and arrangement of...

Data from: Genetic depletion at adaptive but not neutral loci in an endangered bird species

Stefanie A. Hartmann, H. Martin Schaefer & Gernot Segelbacher
Many endangered species suffer from the loss of genetic diversity, but some populations may be able to thrive even if genetically depleted. To investigate the underlying genetic processes of population bottlenecks, we apply an innovative approach for assessing genetic diversity in the last known population of the endangered Pale-headed Brushfinch (Atlapetes pallidiceps) in Ecuador. First, we measure genetic diversity at eleven neutral microsatellite loci and adaptive SNP variation in five Toll-like receptor (TLR) immune system...

Data from: Genome size variation affects song attractiveness in grasshoppers: evidence for sexual selection against large genomes

Holger Schielzeth, Corinna Streitner, Ulrike Lampe, Alexandra Franzke & Klaus Reinhold
Genome size is largely uncorrelated to organismal complexity and adaptive scenarios. Genetic drift as well as intragenomic conflict have been put forward to explain this observation. We here study the impact of genome size on sexual attractiveness in the bow-winged grasshopper Chorthippus biguttulus. Grasshoppers show particularly large variation in genome size due to the high prevalence of supernumerary chromosomes that are considered (mildly) selfish, as evidenced by non-Mendelian inheritance and fitness costs if present in...

Data from: Pollination mitigates cucumber yield gaps more than pesticide and fertilizer use in tropical smallholder gardens

Iris Motzke, Teja Tscharntke, Thomas C. Wanger & Alexandra-Maria Klein
1. Pollination can be an essential but often neglected ecosystem service to mitigate crop yield gaps. Pollination services are usually studied in isolation and their relative role and possible interactions with other factors, such as major management practices, is little understood. 2. We tested how pollination (insect versus wind- and self-pollination) interacts with weed control, fertilization, and insect herbivore control and how these factors as well as flower-visiting bees influence fruit set and yield of...

Data from: The smell of parents: breeding status influences cuticular hydrocarbon pattern in the burying beetle Nicrophorus vespilloides

Sandra Steiger, Klaus Peschke, Wittko Francke & Josef K. Müller
The waxy layer of the cuticle has been shown to play a fundamental role in recognition systems of insects. The biparental burying beetle Nicrophorus vespilloides is known to have the ability to discriminate between breeding and non-breeding conspecifics and also here cuticular substances could function as recognition cue. However, it has not yet been demonstrated that the pattern of cuticular lipids can reflect the breeding status of a beetle or of any other insect. With...

Data from: Rapid species-level identification of vaginal and oral lactobacilli using MALDI-TOF MS analysis and 16S rDNA sequencing

Background: Lactobacillus represents a large genus with different implications for the human host. Specific lactobacilli are considered to maintain vaginal health and to protect from urogenital infection. The presence of Lactobacillus species in carious lesions on the other hand is associated with progressive caries. Despite their clinical significance, species-level identification of lactobacilli still poses difficulties and mostly involves a combination of different phenotypic and genotypic methods. This study evaluated rapid MALDI-TOF MS analysis of vaginal...
