Freshwater Fish Invasions: A Comprehensive Review

Annual Review of Ecology Evolution and Systematics, Год журнала: 2022, Номер 53(1), С. 427 - 456

Опубликована: Сен. 3, 2022

Freshwater fish have been widely introduced worldwide, and freshwater ecosystems are among those most affected by biological invasions. Consequently, invasions one of the documented animal taxa, with much information available about invasive species, their characteristics, invaded regions, invasion pathways, impacts, management. While existing reviews address specific aspects invasions, there is still a gaping lack comprehensive assessments that simultaneously pivotal connected elements process. Here, we provide holistic review, together quantitative assessments, divided into four major parts: ( a) introduction b) characteristics nonnative species andinvaded explain successful processes, c) impacts mechanisms, d) We highlight data gaps biases in current databases basic understanding several In addition, recommendations for future studies.

Preventing and controlling nonnative species invasions to bend the curve of global freshwater biodiversity loss

Environmental Reviews, Год журнала: 2023, Номер 31(2), С. 310 - 326

Опубликована: Янв. 11, 2023

The Emergency Recovery Plan for freshwater biodiversity recognizes that addressing nonnative species is one of six principal actions needed to bend the curve in loss. This because introduction rates continue accelerate globally and where these develop invasive populations, they can have severe impacts on biodiversity. most effective management measure protect prevent introductions species. Should a be introduced, however, then its early detection implementation rapid reaction measures avoid it establishing dispersing. If are unsuccessful becomes invasive, control containment minimize further spread impact. Minimizing impact includes methods reduce invader abundance such as screening invaded sites strict biosecurity dispersing neighbouring basins. These benefitted from developments invasion risk assessment prioritize according their and, already ensure commensurate with assessed risk. successful still requires overcoming some challenges, including often being symptom degraded habitats rather than main driver ecological change, eradication nonspecies specific. Given multiple anthropogenic stressors freshwaters, must work other restoration strategies if deliver

Environmental DNA Methods for Ecological Monitoring and Biodiversity Assessment in Estuaries

Estuaries and Coasts, Год журнала: 2022, Номер 45(7), С. 2254 - 2273

Abstract Environmental DNA (eDNA) detection methods can complement traditional biomonitoring to yield new ecological insights in aquatic systems. However, the conceptual and methodological frameworks for eDNA interpretation were developed primarily freshwater environments have not been well established estuaries marine that are by nature dynamic, turbid, hydrologically complex. context species life history critical successful application of methods, challenges associated with subject a symposium held at University California Davis on January 29, 2020 ( https://marinescience.ucdavis.edu/engagement/past-events/edna ). Here, we elaborate upon topics addressed evaluate monitoring biodiversity studies estuaries. We first provide concise overview science then examine San Francisco Estuary (SFE) as case study illustrate how programs regional guidance future potential applications. Additionally, offer recommendations enhancing communication between scientists natural resource managers, which is essential integrating into existing programs. Our intent create accessible those outside field eDNA, especially without oversimplifying or advantages these methods.

Vector control reduces the rate of species invasion in the world's largest freshwater ecosystem

Conservation Letters, Год журнала: 2022, Номер 15(2)

Abstract The Great Lakes‐St Lawrence River basin is the world's most invaded freshwater system. Ballast water release from transoceanic shipping deemed responsible for 65% of invasions in since modern St. Seaway opened 1959. Regulations requiring mid‐ocean exchange ballast applied 1993 failed to stem ship‐mediated because procedure was not mandated all ships. In 2006 and 2008, Canada United States, respectively, that ships should conduct open ocean flushing ensure partially filled tanks intended discharge into Lakes contained salinity ≥30 ppt before entering Seaway. These regulations have been strictly enforced through record inspections tests tank salinities inbound Before‐and‐after comparisons total organismal abundance species richness revealed a substantial reduction invasion risk conducted saltwater flushing. Since 2006, rate discovery newly established non‐native declined by 85% its lowest level two centuries. While multiple factors could plausibly contribute this decline, empirical evidence supports 2006/2008 regulation as primary cause, highlighting benefit internationally coordinated vector control.

Dramatic changes in the structure of shallow-water marine benthic communities following the invasion by Rugulopteryx okamurae (Dictyotales, Ochrophyta) in Azores (NE Atlantic)

Marine Pollution Bulletin, Год журнала: 2022, Номер 175, С. 113358 - 113358

Опубликована: Янв. 25, 2022

Biological invasions are considered one of the most important drivers biodiversity loss. Here we use a before-after-control-impact (BACI) design to investigate impact Rugulopteryx okamurae on structure shallow-water marine benthic communities in São Miguel island, Azores. After its first appearance 2019, R. has rapidly invaded much southern coast where it became dominant algae. This was followed by significant changes communities, with substantial losses natural variability and species richness. Compared before, there been dramatic reductions abundances articulated coralline algae, corticated algae foliose locations. These results highlight highly invasive character, not seen other, more well-known, species. It remains be investigated if impacts persist throughout time quantify functional consequences such changes.

Citizen science is a vital partnership for invasive alien species management and research

iScience, Год журнала: 2023, Номер 27(1), С. 108623 - 108623

Опубликована: Дек. 3, 2023

Invasive alien species (IAS) adversely impact biodiversity, ecosystem functions, and socio-economics. Citizen science can be an effective tool for IAS surveillance, management, research, providing large datasets over wide spatial extents long time periods, with public participants generating knowledge that supports action. We demonstrate how citizen has contributed across the biological invasion process, especially early detection distribution mapping. However, we recommend could used more assessing impacts evaluating success of management. does have limitations, explore solutions to two key challenges: ensuring data accuracy dealing uneven coverage potential recorders (which limits dataset's "fit purpose"). Greater co-development stakeholders will help us better realize its process ecosystems globally while meeting needs participants, local communities, scientists, decision-makers.

The rapid growth in genomic techniques provides the potential to transform how we protect, manage, and conserve marine life. Further, solutions boost resilience of species climate change other disturbances that characterize Anthropocene require transformative approaches, made more effective if guided by data. Although genetic have been employed conservation for decades availability data is rapidly expanding, widespread application still lags behind types.

Biological invasions and invasive species in freshwaters: perception of the general public

Human Dimensions of Wildlife, Год журнала: 2023, Номер 29(1), С. 48 - 63

Опубликована: Фев. 13, 2023

For management strategies aimed at biological invasions, a detailed survey of the general public's knowledge is crucial. this purpose, our present study to (i) investigate level comprehension regarding (ii) assess ability responders discriminate between invasive and native species, (iii) evaluate conservation support. Increased awareness invasions on part respondents positively influences willingness protect fish crayfish species not their counterparts. Higher identification scores by participants significantly decreased support species. Female were more willing including ones. Respondents could better extent than crayfish. Without public citizen-aimed education, we will be unable conduct sustainable prevent further species' introductions translocations.
