JOURNAL ARTICLE
Jrg Freyhof, Baran Yourtuolu
The Aegean Luciobarbus graecus, L. lydianus, and L. kottelati were described based on morphological characters. However, re-examination of fresh material from the three species revealed greater intraspecific variability in morphological character states, and wider overlaps in all postulated diagnostic traits than initially documented. Consequently, it is not possible to identify and distinguish these three species based solely on morphological characteristics. As they also share identical COI barcode sequences, these species are now considered conspecifics, and L...

REVIEW
Navdeep Kaur, Pratap Kumar Pati
Retron library recombineering (RLR) is a powerful tool in the field of genome editing that exceeds the scope and specificity of the CRISPR/Cas technique. In RLR, single-stranded DNA produced in vivo by harnessing the in-built potential of bacterial retrons is used for replication-dependent genome editing. RLR introduces several genomic variations at once, resulting in pooled and barcoded variant libraries, thus permitting multiplexed applications. Retron-generated RT-DNA has already shown promise for use in genome editing...

In Earth's history warm and cold periods have alternated. Especially, during the Pleistocene, the alternation between these different climatic conditions has led to frequent range expansions and retractions of many species: while thermophilic species dispersed during warm periods, cold adapted species retracted to cold refugia and vice versa. After the last Pleistocene cycle many cold adapted taxa found refuges in relict habitats in mountain ranges. One example for such a cold adapted relict is the flightless snow fly Chionea araneoides (Dalman, 1816)...

The occurrence of a small specimen of Brosme brosme (Gadiformes: Lotidae) from the Porcupine Bank is reported. A single specimen with a total length of 73.2 mm was caught with bottom trawl at a depth of 322 m depth in 2017. The specimen was identified morphologically and confirmed by molecular taxonomy using DNA barcoding. Based on the size and ontogenetic characters found, the specimen was identified as a post-larval individual, and a pelagic habitat of the specimen seems more likely.

Understanding the genetic structure of populations and the processes responsible for its spatial and temporal dynamics is vital for assessing species' adaptability and survival in changing environments. We investigate the genetic fingerprinting of blooming populations of the marine diatom Pseudo-nitzschia multistriata in the Gulf of Naples (Mediterranean Sea) from 2008 to 2020. Strains were genotyped using microsatellite fingerprinting and natural samples were also analysed with Microsatellite Pool-seq Barcoding based on Illumina sequencing of microsatellite loci...

BACKGROUND: The era of high throughput sequencing offers new paths to identifying species boundaries that are complementary to traditional morphology-based delimitations. De novo species delimitation using traditional or DNA super-barcodes serve as efficient approaches to recognizing putative species (molecular operational taxonomic units, MOTUs). Tea plants (Camellia sect. Thea) form a group of morphologically similar species with significant economic value, providing the raw material for tea, which is the most popular nonalcoholic caffeine-containing beverage in the world...

Metabolite biosensors, through which the intracellular metabolite concentrations could be converted to changes in gene expression, are widely used in a variety of applications according to the different output signals. However, it remains challenging to fine-tune the dose-response relationships of biosensors to meet the needs of various scenarios. On the other hand, the short read length of next-generation sequencing (NGS) has greatly limited the design capability of sequence libraries. To address these issues, we describe a DNA trackable assembly method, coupled with fluorescence-activated cell sorting and NGS (Sort-Seq), to achieve the characterization of dose-response curves in a massively parallel manner...

Palearctic water frogs (genus Pelophylax) are an outstanding model in ecology and evolution, being widespread, speciose, either threatened or threatening to other species through biological invasions, and capable of siring hybrid offspring that escape the rules of sexual reproduction. Despite half a century of genetic research and hundreds of publications, the diversity, systematics and biogeography of Pelophylax still remain highly confusing, in no small part due to a lack of correspondence between studies...

In this study, we focus on training recurrent spiking neural networks to generate spatiotemporal patterns in the form of closed two-dimensional trajectories. Spike trains in the trained networks are examined in terms of their dissimilarity using the Victor-Purpura distance. We apply algebraic topology methods to the matrices obtained by rank-ordering the entries of the distance matrices, specifically calculating the persistence barcodes and Betti curves. By comparing the features of different types of output patterns, we uncover the complex relations between low-dimensional target signals and the underlying multidimensional spike trains...
