Directed cell migration and target recognition are critical for the development of both the nervous and muscular systems. Molecular mechanisms that control these processes in the nervous system have been intensively studied, whereas those that act during muscle development are still largely uncharacterized. Here we identify a transmembrane protein, Kon-tiki (Kon), that mediates myotube target...

Single nucleotide polymorphisms (SNPs) are useful markers for genetic mapping experiments in model organisms. Here we report the establishment of a high-density SNP map and high-throughput genotyping assays for Drosophila melanogaster. Our map comprises 27,367 SNPs in common laboratory Drosophila stocks. These SNPs were clustered within 2,238 amplifiable markers at an average density of 1 marker...

Germ cells, the cells that give rise to sperm and egg, maintain the potential to recreate all cell types in a new individual. This wide developmental potential, or totipotency, is manifested in unusual tumors called teratomas, in which germ cells undergo somatic differentiation. Although recent studies have implicated RNA regulation, the mechanism that normally prevents the loss of germ cell...

Although the decision between stem cell self‐renewal and differentiation has been linked to cell‐cycle modifications, our understanding of cell‐cycle regulation in stem cells is very limited. Here, we report that FBF/Pumilio, a conserved RNA‐binding protein, promotes self‐renewal of germline stem cells by repressing CKI‐2Cip/Kip, a Cyclin E/Cdk2 inhibitor. We...

A number of Ponto-Caspian gobiid species are currently invading European coasts and freshwaters. They do not only present a nuisance to fishermen, but evidence suggests that they compete with native benthic fishes and may contribute to changes in ecosystem function. This paper reports the presence of round goby Neogobius melanostomus individuals and an established population of bighead goby...

The number of non-native fish species in our water bodies isincreasing in the course of globalisation. They navigate artificial canals, travel in ballast water of ships or are displaced as eggs attached to ships and other materials. Many of these species remain unnoticed but some may establish a reproductive population and even cause harm. Invasive gobies from the Black Sea – especially the...

Limited information is available on artisanal and subsistence shark fisheries across the Pacific. The aim of this study was to investigate Fiji’s inshore fisheries which catch sharks. In January and February 2013, 253 semi-directive interviews were conducted in 117 villages and at local harbours on Viti Levu, Vanua Levu, Taveuni, Ovalau and a number of islands of the Mamanuca and Yasawa...

Ponto-Caspian gobies are a flock of five invasive fish species that have colonized freshwaters and brackish waters in Europe and North America. One of them, the round goby Neogobius melanostomus, figures among the 100 worst invaders in Europe. Current methods to detect the presence of Ponto-Caspian gobies involve catching or sighting the fish . These approaches are labor intense and not very...

Colonization events, range expansions and species invasions leave genetic signatures in the genomes of invasive organisms and produce intricate special patterns. Predictions have been made as to how those patterns arise, but only very rarely, genetic processes can be monitored in real time during range expansions. In an attempt to change that, we track a very recently established invasive...

Managing invasive species is a major challenge for society. In the case of newly established invaders, rapid action is key for a successful management. Here, we develop, describe and recommend a three-step transdisciplinary process (the “butterfly model”) to rapidly initiate action for invasion management. In the framing of a case study, we present results from the first of these...

We report the first complete mitochondrial genome (mitogenome) of an invasive Ponto-Caspian goby, Ponticola kessleri (bighead goby, Gu¨ nther 1891). Ion Torrent PGM sequencing oftotal DNA from two individuals yielded a contig of 16,971 bp, with overlapping ends located inthe repetitive control region, which was validated using Sanger sequencing. The finalmitogenome of Ponticola kessleri has a...

Invasive species are one of the greatest threats to biodiversity worldwide, and to successfully manage their introductions is a major challenge for society. Knowledge on the impacts of an invasive species is essential for motivating decision makers and optimally allocating management resources. We use a prominent invasive fish species, the round goby (Neogobius melanostomus) to objectively...

Non-native invasive species are a major threat to biodiversity, especially in freshwater ecosystems. Freshwater ecosystems are naturally rather isolated from one another. Nonetheless, invasive species often spread rapidly across water sheds. This spread is to a large extent realized by human activities that provide vectors. For example, recreational boats can carry invasive species propagules as...

Background: Vertebrate mitochondrial genomes are optimized for fast replication and low cost of RNA expression. Accordingly, they are devoid of introns, are transcribed as polycistrons and contain very little intergenic sequences. Usually, vertebrate mitochondrial genomes measure between 16.5 and 17 kilobases (kb). Results: During genome sequencing projects for two novel vertebrate models, the...

Sharks are an important component of coastal fisheries. Accordingly, the impacts of small-scale shark fisheries are likely significant, but data, including socio-economic drivers, are often scarce. Fiji features active but largely unregulated and unmonitored artisanal fisheries. Data suggest that the country's small-scale shark fisheries have the potential to become more targeted. This study...

It has been proposed that non-genetic inheritance could promote species fitness. Non-genetic inheritance could allow offspring to benefit from the experience of their parents, and could advocate pre-adaptation to prevailing and potentially selective conditions. Indeed, adaptive parental effects have been modeled and observed, but the molecular mechanisms behind them are far from understood. In the...

The vast majority of global freshwater ecosystems are small lakes with less than 100 m 2 surface area. These lakes are often unconnected to other water bodies but frequently host fish populations. Existing explanations for how fish colonize such remote habitats often involve birds as vectors transporting fish eggs as propagules. In this study, we aim to quantify the prevalence of these...

1. When prevention of invasive species' introductions fails, society faces the challenge to manage invasive species in an effective and efficient way. The success of this depends on biological aspects and on cooperation between decision makers and scientists. Using the case of the round goby Neogobius melanostomus, one of Europe's "worst invasive species", we propose an approach guiding scientists...

Genetic innovation may be linked to evolutionary success, and indeed, the invasive round goby mitochondrial genome sequence carries two novel features not previously described in Benthophilinae. First, the round goby mitochondrial genome carries a rearrangement of the tRNA cluster Ile-Glu-Met. Second, the round goby mitochondrial genome features a 1250 bp non-coding sequence insertion downstream...
