BIORXIV 11/06/20 Speeding up the detection of invasive aquatic species using environmental DNA and nanopore sequencing.

Résumé traduit : La détection traditionnelle des espèces aquatiques envahissantes, via l'identification morphologique, prend souvent du temps et peut exiger un haut niveau d'expertise taxonomique, ce qui entraîne des réponses d'atténuation retardées. Des approches de détection de l'ADN environnemental (eDNA) de plusieurs espèces utilisant la technologie de séquençage basée sur Illumina ont été utilisées pour surmonter ces obstacles, mais le traitement des échantillons est souvent long. Plus récemment, la technologie de séquençage des nanopores portables est devenue disponible, qui a le potentiel de rendre la détection moléculaire d'espèces envahissantes plus largement accessible et de réduire considérablement les délais de traitement des échantillons. Cependant, les lectures séquencées par nanopores ont un taux d'erreur beaucoup plus élevé que celles produites par les plates-formes Illumina, ce qui a jusqu'à présent entravé l'adoption de cette technologie. Nous fournissons un protocole de laboratoire détaillé et des outils bioinformatiques pour augmenter la fiabilité du séquençage des nanopores pour détecter les espèces envahissantes, et nous testons son application à l'aide de bivalves invasifs. Nous avons échantillonné l'eau de sites contenant des données d'occurrence et d'abondance de bivalves préexistantes et de communautés de bivalves contrastées, en Italie et au Portugal. Nous avons extrait, amplifié et séquencé l'ADNe avec un délai de 3,5 jours. La majorité des lectures traitées étaient ≥ 99% identiques aux séquences de référence. Aucun taxon n'a été détecté autre que ceux connus. Le manque de détection de certaines espèces sur certains sites pourrait s'expliquer par leurs faibles abondances connues. Il s'agit de la première utilisation signalée de MinION pour détecter des espèces aquatiques envahissantes à partir d'échantillons d'ADN électronique. L'approche peut être facilement adaptée à d'autres applications de métabarcodage, telles que l'évaluation de la biodiversité, l'évaluation de la santé des écosystèmes et les études de régime. – guatemalt

PLOS - 2018 - Functional feeding traits as predictors of invasive success of alien freshwater fish species using a food-fish model

Since 2002, at least five Ponto-Caspian alien fish species have arrived in The Netherlands. Four species belong to the Gobiidae family (Neogobius fluviatilis, Neogobius melanostomus, Ponticola kessleri, and Proterorhinus semilunaris) and one to the Cyprinidae family (Romanogobio belingi). These species are expected to be potentially deleterious for the populations of four native benthic fish species: Gobio gobio (Cyprinidae), Barbatula barbatula (Nemacheilidae), Cottus perifretum, and C. rhenanus (Cottidae). Invasion success may be dependent on competitive trophic interactions with native species, which are enabled and/or constrained by feeding-related morphological traits.

MICHIGAN STATE UNVIERSITY 23/10/17 Aquatic invasive species: fighting an ongoing threat

Posted on October 23, 2017 by Beth Clawson, Michigan State University Extension In the early 2000s, there was a call from several scientific, environmental and economic sectors calling for controls, standards and management frameworks for reducing the risks and damage of aquatic invasive species in Michigan. Over 182 non-indigenous aquatic species were introduced and colonized within the Great Lakes region since the 1800s.

NEW SCIENTIST 09/09/16 Global treaty set to halt invasive species ravaging our oceans

A global convention to stop this happening was formally triggered on 8 September, more than two decades after it was proposed, and will officially come into force a year from then. The convention will compel many of the world’s 70,000 or so registered cargo ships to install equipment guaranteed to kill off any aquatic creatures in seawater taken on board to maintain stability. Advertisement The arrival of the comb jelly (pictured top) in the Black, Azov and Caspian seas from its home on the east coast of North America caused the catastrophic collapse of fisheries in the 1990s.

Crossing in the opposite direction as larvae, zebra mussels (pictured below) have caused an estimated $1 billion worth of damage between 1989 and 2000 in the US Great Lakes by blocking water intake pipes.

An ocean heavily populated by invasive species of algae, jellyfish, crabs and shellfish may be the future if ocean acidification continues.

RDMAG 11/10/15 Ocean Acidification May Help Invasive Species Rise

“A rapidly growing body of research indicates that ocean acidification will severely disrupt marine ecosystems, since it alters the balance of success between competing organisms. Ocean acidification can impact a wide range of processes across marine taxa, including photosynthesis, acid-base homeostasis, calcification and behavior,” Plymouth Univ. researchers write in Research and Reports in Biodiversity Studies. However, “the traits that help many invasive organisms succeed, such as wider physiological tolerance and reproductive advantage in the face of multiple stressors, are traits that look set to help them in an acidifying ocean.”

The study was prompted when Prof. Jason Hall-Spencer, the study’s lead author, witnessed the marine life thriving near volcanic sites in the Mediterranean.

In 1989, the oil tanker Exxon Valdez ran aground in Alaska, spilling millions of liters of crude oil and killing hundreds of thousands of marine mammals and birds.

HAKAI MAGAZINE 24/06/16 Ballast Water Exemptions Are Leaving Alaska Open to Invasion

It was one of the worst environmental disasters in history. Alaska’s coast has, fortunately, not seen a repeat event since. But every day, Alaska’s ecosystem is endangered by oil tankers—though in a far more subtle way. Before they travel the world’s oceans, oil tankers and other large ships that are not carrying cargo will suck up as much as tens of millions of liters of water into tanks to help maintain balance and stability.

When a tanker reaches port in Alaska and is preparing to take on oil, it will dump this water into the sea. The main problem with ballast water is that ships are often near the shore when they fill their tanks, and are near the shore again when they discharge the water at their destination, which might be thousands of kilometers away. But that will only happen if progress continues.

DOVEPRESS 13/01/16 Marine biosecurity: protecting indigenous marine species

If these species then threaten indigenous species and biodiversity, and/or cause economic damage, they are referred to as “invasive.” Biological invasions are not only one of the greatest threats to indigenous marine biodiversity, but they can also cause massive economic and ecological damage. Their presence could also lead to a water body failing to achieve good environmental status under the forthcoming EU Marine Strategy Framework Directive.

PLOS 15/04/15 Classification of Non-Indigenous Species Based on Their Impacts: Considerations for Application in Marine Management. Abstract Assessment of the ecological and economic/societal impacts of the introduction of non-indigenous species (NIS) is one of the primary focus areas of bioinvasion science in terrestrial and aquatic environments, and is considered essential to management.

PLOS 15/04/15 Classification of Non-Indigenous Species Based on Their Impacts: Considerations for Application in Marine Management

A classification system of NIS, based on the magnitude of their environmental impacts, was recently proposed to assist management. Here, we consider the potential application of this classification scheme to the marine environment, and offer a complementary framework focussing on value sets in order to explicitly address marine management concerns.
