Understanding how natural selection shapes genetic variation in populations is of paramount importance evolutionary biology. Affordable high-throughput sequencing now allows the generation genome-wide data for non-model species, thereby stimulating research aimed at determining genomic basis adaptation to local environmental conditions. However, although these adaptive loci show characteristic signatures positive selection, several other processes can lead similar patterns, rendering search...
The field of molecular ecology is transitioning from the use small panels classical genetic markers such as microsatellites to much larger single nucleotide polymorphisms (SNPs) generated by approaches like RAD sequencing. However, few empirical studies have directly compared ability these methods resolve population structure. This could implications for understanding phenotypic plasticity, many previous natural populations may lacked power detect differences, especially over...
Arctic phytoplankton and their response to future conditions shape one of the most rapidly changing ecosystems on planet. We tested how much phenotypic responses strains from same diatom population diverge whether physiology intraspecific composition multistrain populations differs expectations based single strain traits. To this end, we conducted incubation experiments with Thalassiosira hyalina under present-day temperature pCO2 treatments. Six fresh isolates Svalbard were incubated as...
DNA barcoding utilizes short standardized sequences to identify species and is increasingly used in biodiversity assessments. The technique has unveiled an unforeseeably high number of morphologically cryptic species. However, if speciation occurred relatively recently rapidly, the use single gene markers, especially exclusive mitochondrial will presumably fail delimitating Therefore, true biological might be even higher. One mechanism that can result rapid hybridization different...
Abstract An increasing number of phylogenetic studies have reported discordances among nuclear and mitochondrial markers. These discrepancies are highly relevant to widely used biodiversity assessment approaches, such as DNA barcoding, that rely almost exclusively on Although the theoretical causes mito‐nuclear well understood, it is often extremely challenging determine principal underlying factor in a given study system. In this study, we uncovered significant pair sibling caddisfly...
Water flow in river networks is frequently regulated by man-made in-stream barriers. These obstacles can hinder dispersal of aquatic organisms and isolate populations leading to the loss genetic diversity. Although millions small barriers exist worldwide, their impact on macroinvertebrates remains unclear. Therefore, we, therefore, assessed effects such population structure effective five macroinvertebrate species with strictly life cycles: amphipod crustacean Gammarus fossarum (clade 11),...
Abstract Effective identification of species using short DNA fragments (DNA barcoding and metabarcoding) requires reliable sequence reference libraries known taxa. Both taxonomically comprehensive coverage content quality are important for sufficient accuracy. For aquatic ecosystems in Europe, barcode particularly if molecular tools to be implemented biomonitoring reports the context EU Water Framework Directive (WFD) Marine Strategy (MSFD). We analysed gaps two most databases, Barcode Life...
The larval stages of the central European sibling caddisfly species Sericostoma personatum (Spence in Kirby and Spence, 1826) S. flavicorne Schneider, 1845 are morphologically similar can only be distinguished by differences coloration late instars. Identification using mitochondrial barcoding gene, i.e., Cytochrome c Oxidase 1, is impossible, as both share same highly differentiated haplotypes due to introgression. Nuclear gene markers obtained through double digest restriction site...
Abstract Owing to the intensified domestication process with artificial trait selection, introgressive hybridisation between domestic and wild species poses a management problem. Traditional free-range livestock husbandry, as practiced in Corsica Sardinia, is known facilitate boars pigs ( Sus scrofa ). Here, we assessed genetic distinctness genome-wide pig ancestry levels of Corsican boar subspecies S. s. meridionalis , reference its Sardinian conspecifics, employing single nucleotide...
High-throughput sequencing (HTS) studies on invertebrates commonly use ethanol as the main sample fixative (upon collection) and preservative (for storage curation). However, alternative agents exists, which should not be automatically neglected when are newly designed. This review provides an overview of application propylene glycol (PG) in DNA-based invertebrates, thus to stimulate evidence-based discussion. The PG is still limited (n = 79), but a steady increase has been visible since...
High-throughput sequencing makes it possible to evaluate thousands of genetic markers across genomes and populations. Reduced-representation approaches, like double-digest restriction site-associated DNA (ddRADseq), are frequently applied screen for variation. In particular in nonmodel organisms where whole-genome is not yet feasible, ddRADseq has become popular as allows genomewide assessment variation patterns even the absence other genomic resources. However, while many tools available...
Abstract Genetic identification methods have become increasingly important for species that are difficult to identify in the field. A case point is Pelophylax water frogs. While their morphological determination highly complex, they include protected under EU law and some classified as invasive. Additionally, genetic data can provide insights into complex breeding systems, which may or not involve reproductive dependency of one on another. Here, we generate baseline frog monitoring...
This manuscript summarizes the outcomes of 6th EuroSpeleo Protection Symposium. Special emphasis was laid on presenting and discussing monitoring activities under umbrella Habitats Directive (EU Council 92/43/EEC) for habitat type 8310 "Caves not open to public" Emerald Network. The discussions revealed a high level variation in currently conducted underground activities: there is no uniform definition what kind environments "cave" should cover, how often specific cave has be monitored,...
The subterranean karst environment (terrestrial, semi-aquatic and aquatic components) is unique containing a high diversity of species with specific morphologic, physiologic, metabolic adaptations (Moldovan et al., 2018). fragile nature this poses significant challenges when dealing biodiversity safeguarding its habitats protection against increasing threats human activities (Mammola 2019).
Molecular species identification with DNA metabarcoding can potentially accelerate, streamline and standardise biomonitoring routines. Currently, it is tested how this new technique be implemented for the European Water Framework Directive (WFD) Marine Strategy (MSFD). To connect results from current monitoring routines, an extensive, high-quality barcode reference database required. Hence, a gap-analysis of Barcode Life Data Systems (BOLD) was performed as part EU-COST Action DNAqua-Net...
