Data from: Skin swabbing of amphibian larvae yields sufficient DNA for efficient sequencing and reliable microsatellite genotyping
Skin swabbing, a minimally invasive DNA sampling method recently developed on adult amphibians, was tested on larvae of fire salamanders (Salamandra salamandra). The quality and quantity of the sampled DNA was evaluated by (i) measuring DNA concentration in DNA extracts, (ii) sequencing part of the mtDNA cytochrome b gene (692 bp) and (iii) genotyping eight polymorphic nuclear microsatellite loci. The multiple-tubes approach was used for calculating allelic dropout (ADO) and false allele (FA) rates to evaluate the reliability of the genotypes. DNA extracts from tissue samples of road-killed individuals were included in the study as positive controls. Our results showed that skin swabs of fire salamander larvae can provide DNA in sufficient quantity and quality, as sequencing was successful and no allelic dropouts or false alleles were detected. This method, tested for the first time on amphibian larvae, has proven to be an efficient and reliable alternative to the controversial tail fin clipping procedure.
Data from: Do aggressive signals evolve toward higher reliability or lower costs of assessment?
It has been suggested that the evolution of signals must be a wasteful process for the signaller, aimed at the maximization of signal honesty. However, the reliability of communication depends not only on the costs paid by signallers but also on the costs paid by receivers during assessment, and less attention has been given to the interaction between these two types of costs during the evolution of signalling systems. A signaller and receiver may accept some level of signal dishonesty by choosing signals that are cheaper in terms of assessment but that are stabilized with less reliable mechanisms. I studied the potential trade-off between signal reliability and the costs of signal assessment in the corncrake (Crex crex). I found that the birds prefer signals that are less costly regarding assessment rather than more reliable. Despite the fact that the fundamental frequency of calls was a strong predictor of male size, it was ignored by receivers unless they could directly compare signal variants. My data revealed a response advantage of costly signals when comparison between calls differing with fundamental frequencies is fast and straightforward, whereas cheap signalling is preferred in natural conditions. These data might improve our understanding of the influence of receivers on signal design because they support the hypothesis that fully honest signalling systems may be prone to dishonesty based on the effects of receiver costs and be replaced by signals that are cheaper in production and reception but more susceptible to cheating.
Data from: Scrutinizing key steps for reliable metabarcoding of environmental samples
1. Metabarcoding of environmental samples has many challenges and limitations that require carefully considered laboratory and analysis pipelines to ensure reliable results. We explore how decisions regarding study design, laboratory work and bioinformatic processing affect the final results, and provide guidelines for reliable study of environmental samples. 2. We evaluate the performance of four primer sets targeting COI and 16S regions characterising arthropod diversity in bat faecal samples, and investigate how metabarcoding results are affected by parameters including: i) number of PCR replicates per sample, ii) sequencing depth, iii) PCR replicate processing strategy (i.e. either additively, by combining the sequences obtained from the PCR replicates, or restrictively, by only retaining sequences that occur in multiple PCR replicates for each sample), iv) minimum copy number for sequences to be retained, v) chimera removal, and vi) similarity thresholds for OTU clustering. Lastly, we measure within- and between-taxa dissimilarities when using sequences from public databases to determine the most appropriate thresholds for OTU clustering and taxonomy assignment. 3. Our results show that the use of multiple primer sets reduces taxonomic biases and increases taxonomic coverage. Taxonomic profiles resulting from each primer set are principally affected by how many PCR replicates are carried out per sample and how sequences are filtered across them, the sequence copy number threshold and the OTU clustering threshold. We also report considerable diversity differences between PCR replicates from each sample. Sequencing depth increases the dissimilarity between PCR replicates unless the bioinformatic strategies to remove allegedly artefactual sequences are adjusted according to the number of analysed sequences. Finally, we show that the appropriate identity thresholds for OTU clustering and taxonomy assignment differ between target markers. 4. Metabarcoding of complex environmental samples ideally requires i) investigation of whether more than one primer sets targeting the same taxonomic group is needed to offset the effect of primer biases, ii) more than one PCR replicate per sample, iii) bioinformatic processing approaches of sequences that balance diversity detection with removal of artificial sequences, and iv) empirical selection of OTU clustering and taxonomy assignment thresholds tailored to each genetic marker and the obtained taxa.

Automated Pattern-Based Recommendation for Improving API Operation Performance and Reliability in Cloud-Based Architectures
<p>The extensive use of APIs as the entry point to many Cloud-based applications has created challenging problems, especially concerning API quality properties such as performance and reliability. API best practices and patterns, such as bundling requests, rate limiting, or load balancing, have been proposed to solve these challenges. Unfortunately, no study investigating the impact of existing API practices and patterns on such quality properties exists beyond informal recommendations. In this paper, we fill this gap by proposing a pattern-based, automated recommendation approach to improve the performance and reliability of API operations. We provide a benchmark suite based on a realistic open-source microservice application to enable the automatic generation of comprehensive decision tree models. These models are then processed to generate API design recommendation algorithms to improve API operations regarding performance and reliability stored in catalogs for reuse. We validate our algorithms using extensive data sets generated by running the benchmark on a private cloud and AWS. For both environments, based on the decision tree models automatically generated from the measured data, API design recommendation algorithms have been calculated using our approach.</p>

Data from: probing variation in reaction norms in wild populations: the importance of reliable environmental proxies
<p><span>Many traits are phenotypically plastic, i.e., the same genotype expresses different phenotypes depending on the environment. Genotypes and individuals can vary in their response to the environment and this genetic (G×E) and individual (I×E) variation in reaction-norm slopes can have important ecological or evolutionary consequences. Studies on I×E/G×E often fail to show slope variation, potentially due to the choice of the environmental covariate. Identifying the genuine environmental driver of phenotypic plasticity (the cue) is practically impossible and hence only proxies can be used. If the proxy is too weakly correlated with the cue, this may lead researchers to conclude there is little or no (variation in) plasticity, and hence lead to downwardly biased estimates of the potential for plastic responses (or evolutionary change in the slope) in response to environmental change. Alternatively, the Environment-Specific Mean phenotype (ESM) across individuals—which captures all environmental effects on the phenotype—as covariate should be less prone to such bias. We showed by simulation—after verifying the concept analytically—that using weakly correlated proxies indeed biased estimates of slope variation vis-à-vis the true cue downward but that ESM as a covariate held up well, even when multiple sources of I×E or an interaction between environments (I×E×E) existed in the data. Analysis of two real datasets revealed that estimated I×E and G×E, respectively, were more sizeable and precise when using ESM as opposed to reasonably informative environmental proxies. We argue that the ESM approach should be adopted by biologists as a yardstick in the study of (variation in) plasticity in the wild and that it may serve as a useful starting point for the search of better environmental proxies and unravelling complex I×E or G×E patterns.</span></p>
