Biogeographical studies have traditionally focused on readily visible organisms, but recent technological advances are enabling analyses of the large-scale distribution microscopic whose biogeographical patterns long been debated. Here we assessed global structure plankton geography and its relation to biological, chemical, physical context ocean (the ‘seascape’) by analyzing metagenomes communities sampled across oceans during Tara Oceans expedition, in light environmental data current...
Eukaryotic plankton are a core component of marine ecosystems with exceptional taxonomic and ecological diversity, yet how their ecology interacts the environment to drive global distribution patterns is poorly understood. In this work, we use Tara Oceans metabarcoding data, which cover all major ocean basins, combined probabilistic model taxon co-occurrence compare biogeography 70 groups eukaryotic plankton. We uncover two main axes biogeographic variation. First, more-diverse display...

Anchovies represent the largest world's marine fish catches and current threats on their populations impose a sustainable exploitment based sound scientific information. In European anchovy (Engraulis encrasicolus), existence of several has been proposed but global view is missing. Using multidisciplinary approach, here we assessed divergence among different ecotypes its possible causes. SNPs have revealed two functionally distinct overlapping in Central Mediterranean, with one ecotype...
Machine learning based surrogate models offer researchers powerful tools for accelerating simulation-based workflows. However, as standard datasets in this space often cover small classes of physical behavior, it can be difficult to evaluate the efficacy new approaches. To address gap, we introduce Well: a large-scale collection containing numerical simulations wide variety spatiotemporal systems. The Well draws from domain experts and software developers provide 15TB data across 16 covering...
Abstract High levels of genetic diversity and connectivity are crucial for the persistence local populations, especially at edge species’ distribution ranges. Here, we assessed potential realized populations Mediterranean seagrass Posidonia oceanica its easternmost using physical modelling analyses. Genetic assessments gene flow among were carried out with 18 microsatellite loci, while oceanographic was via Lagrangian dispersal simulations. Levels clonal diversities prevalent shallow deep...
In recent years, there has been a renewed interest in the impact of turbulence on aquatic organisms. response to this interest, novel instrument constructed, TURBOGEN, that generates water volumes up 13 l. TURBOGEN is fully computer controlled, thus, allowing for high level reproducibility and variations intensity characteristics during experiment. The calibration tests, carried out by particle image velocimetry, showed be successful generating isotropic at typical relatively low levels...
We present a study of Lagrangian intermittency and its characteristic time scales. Using the concepts flying diving residence times above below given threshold in magnitude turbulence quantities, we infer spectra temporal fluctuations dissipation, acceleration enstrophy by means direct numerical simulation homogeneous isotropic turbulence. then relate these scales, first, to presence extreme events and, second, local flow characteristics. Analyses confirm existence turbulent quantities holes...
The distribution functions of field fluctuations the turbulent mixing layer produced by a Rayleigh-Taylor instability (RTI) have long been hypothesized to involve bimodal effects. present work reviews existing quantitative and qualitative evidence in support this conjecture, provides an associated theoretical framework, measures corresponding relevant statistical quantities on simulation RTI at low Atwood number. behaviour fluctuations, readily observable close edges zone, is less obvious...
Flow induced vibration of tube bundles remains an important problem in the nuclear industry. A number theories modeling fluidelastic instability have been developed. In those theories, understanding influence a on its neighbors is primary importance. Since it very difficult and time consuming to measure complete set cross-coupling effects, numerical simulations could provide valuable alternative. The main purpose this paper propose Sensitivity Equation Method (SEM) as new approach finding...
