Abstract Drosophila suzukii ovoposits and feeds on healthy fruits, unlike most other species. It has been traditionally reported from Asia, but in the last 2 years it recorded North America, where is causing a lot of agricultural damage. Herein we report first records of, D. Europe. found different localities expanding an altitudinal range 27 to 1550 m above sea level (ab.s.l). Furthermore by comparing collections drosophilids European populations distributed along latitudinal cline were...
The spatial distribution of neutral genetic diversity is mainly influenced by barriers to dispersal. nature such varies according the dispersal means and capabilities organisms concerned. Although these are often obvious on land, in ocean they can be more difficult identify. Determining relative influence physical biotic factors connectivity remains a major challenge for marine ecologists. Here, we compare gene flow patterns 7 littoral fish species from 6 families with range...
Abstract Drosophila subobscura is a Palearctic species that was first observed in South and North America the early 1980s, rapidly invaded broad latitudinal ranges on both continents. To trace source history of this invasion, we obtained genotypic data nine microsatellite loci from two American, American five European populations D. subobscura. We analysed these with traditional statistics as well an approximate Bayesian computation (ABC) framework. ABC methods yielded strongest support for...
Deciphering invasion routes from molecular data is crucial to understanding biological invasions, including identifying bottlenecks in population size and admixture among distinct populations. Here, we unravel the of invasive pest Drosophila suzukii using a multi-locus microsatellite dataset (25 loci on 23 worldwide sampling locations). To do this, use approximate Bayesian computation (ABC), which has improved reconstruction routes, but can be computationally expensive. We our study...
Genetic connectivity and geographic fragmentation are two opposing mechanisms determining the population structure of species. While first homogenizes genetic background across populations second one allows their differentiation. Therefore, knowledge processes affecting dispersal marine organisms is crucial to understand distribution patterns for effective management populations. In this study, we use analyses eleven microsatellites in combination with oceanographic satellite simulation data...
Genetic variation is the fuel of evolution, with standing genetic especially important for short-term evolution and local adaptation. To date, studies spatiotemporal patterns in natural populations have been challenging, as comprehensive sampling logistically difficult, sequencing entire costly. Here, we address these issues using a collaborative approach, 48 pooled population samples from 32 locations, perform first continent-wide genomic analysis European Drosophila melanogaster. Our...
Abstract Defining the scale of connectivity among marine populations and identifying barriers to gene flow are tasks fundamental importance for understanding genetic structure design reserves. Here, we investigated population at three spatial scales red gorgonian Paramuricea clavata (Cnidaria, Octocorallia), a key species dwelling in coralligenous assemblages Mediterranean Sea. Colonies P. were collected from 39 locations across Sea Morocco Turkey analysed using microsatellite loci. Within...
Sea urchins are emblematic models in developmental biology and display several characteristics that set them apart from other deuterostomes. To uncover the genomic cues may underlie these specificities, we generated a chromosome-scale genome assembly for sea urchin Paracentrotus lividus an extensive gene expression epigenetic profiles of its embryonic development. We found that, unlike vertebrates, retained ancestral chromosomal linkages but underwent very fast intrachromosomal order mixing....
The rates of mutation, recombination, and transposition are core parameters in models evolution. They impact genetic diversity, responses to ongoing selection, levels load. However, even for key evolutionary model species such as Drosophila melanogaster simulans, few estimates these available, we have little idea how vary between individuals, sexes, or populations. Knowledge this variation is fundamental parameterizing genome Here, provide direct their a West African European population D....
Abstract The Catalan Initiative for the Earth BioGenome Project (CBP) is an EBP-affiliated project network aimed at sequencing genome of >40 000 eukaryotic species estimated to live in Catalan-speaking territories (Catalan Linguistic Area, CLA). These represent a biodiversity hotspot. While covering less than 1% Europe, they are home about one fourth all known European species. include high proportion endemisms, many which threatened. This trend likely get worse as effects global...
Drosophila subobscura is geographically widespread in the Old World. Around late 1970s, it was accidentally introduced into both South and North America, where spread rapidly over broad latitudinal ranges. This invading species offers opportunities to study speed predictability of trait evolution on a geographic scale. One special interest body size, which shows strong positive cline many species, including World D. subobscura. Surveys made about decade after invasion found no evidence size...
Abstract Different categories of molecular markers have been used so far to study the population structure sponges. However, these often did not resolution power address precisely questions on structuring processes, especially at intrapopulational level. In this we show that microsatellites fulfil expectations, allowing a fine description different geographical scales in marine sponge Crambe crambe . Specimens were collected 11 locations, representing most Atlanto‐Mediterranean range...
Social dominance is important for the reproductive success of males in many species. In black-faced blenny (Tripterygion delaisi) during season, some change color and invest nest making defending a territory, whereas others do not 'sneak' reproductions when females lay their eggs. Using RNAseq, we profiled differential gene expression between brains territorial males, sneaker to study molecular signatures male dimorphism. We found that more genes were differentially expressed two phenotypes...
Juvenile loggerhead sea turtles (Caretta caretta) from Atlantic nesting populations migrate into the western Mediterranean, where they share feeding grounds with originating in Mediterranean. In this scenario, male-mediated gene flow may lead to homogenization of these distant populations. To test hypothesis, we genotyped 7 microsatellites 56 individuals sampled Mediterranean and then compared observed allele frequencies published data 112 beaches. were found be genetically differentiated...
Native to Asia, the soft-skinned fruit pest Drosophila suzukii has recently invaded United States and Europe. The eastern represents most recent expansion of their range, presents an opportunity test alternative models colonization history. Here, we investigate genetic population structure this invasive fly, with a focus on States. We sequenced six X-linked gene fragments from 246 individuals collected total 12 populations. examine patterns diversity within between populations explore...
The assessment of the genetic structuring biodiversity is crucial for management and conservation. For species with large effective population sizes a low number markers may fail to identify structure. A solution this shortcoming can be high-throughput sequencing that allows genotyping thousands on genome-wide approach while facilitating detection shaped by selection. We used Genotyping-by-Sequencing (GBS) 176 individuals endemic East Atlantic peacock wrasse (Symphodus tinca), from 6...
The colonisation of new suitable habitats is crucial for species survival at evolutionary scale under changing environmental conditions. However, potential may be limited by philopatry that facilitates exploiting successful across generations. We examine the mechanisms long distance dispersal philopatric loggerhead sea turtle (Caretta caretta) analysing 40 sporadic nesting events in western Mediterranean. analysis a fragment mitochondrial DNA and 7 microsatellites 121 samples from 18 these...
