Artificial reefs (ARs) have been used on coral for ecological research, conservation, and socio-cultural purposes since the 1980s. We examined spatio-temporal patterns in AR deployment tropical subtropical (up to 35° latitude) evaluated their efficacy meeting conservation objectives, using a systematic review of scientific literature.

eDNA-Based Early Detection Illustrates Rapid Spread of the Non-Native Golden Mussel Introduced into Beijing via Water Diversion

The world’s largest water diversion, the South-to-North Water Transfer Project (SNWTP) in China, has created an “invasion highway” to introduce invasive golden mussels (Limnoperna fortunei) from Yangtze River basin Beijing. To examine spread and colonization patterns of this newly introduced species, we conducted comprehensive environmental DNA (eDNA)-based early detection conventional field surveys across all bodies five river basins Beijing 2020 2023. Our results indicated a rapid over past four years. Among 130 tested sites, number sites with positive signals eDNA analysis exhibited annual increase: Commencing infested identified through 2019, detected additional 13, 11, 10 2020, 2021, 2022, respectively, substantial rise comprising 28 Conventional 1–3 years later than eDNA-based at 16 sites.

Identifying marine invasion threats and management priorities through introduction pathway analysis in a remote sub‐Antarctic ecosystem

Ecology and Evolution, Год журнала: 2024, Номер 14(4)

Abstract The threat from novel marine species introductions is a global issue. When non‐native are introduced to environments and become invasive, they can affect biodiversity, industry, ecosystem function, both human wildlife health. Isolated areas with sensitive or highly specialised endemic be particularly impacted. increase in the scope of tourism other activities, together rapidly changing climate, now put these remote ecosystems under threat. In this context, we analyse invasion pathways into South Georgia Sandwich Islands (SGSSI) for via vessel biofouling. SGSSI archipelago has high biodiversity endemism, historically been isolated American mainland. islands sit just below Polar Front temperature boundary, affording some protection against introductions. However, region warming increasingly acts as gateway port traffic wider Antarctic, amplifying likelihood. We use Automatic Identification System vessel‐tracking data over 2‐year period map movement behaviour around Georgia, across ‘Scotia Sea’, ‘Magellanic’ northern ‘Continental High Antarctic’ ecoregions. find multiple types locations globe frequently enter shallow inshore waters stop prolonged periods (weeks/months) at anchor.

In the aftermath of Hurricane Irma: Colonization of a 4-year-old shipwreck by native and non-native corals, including a new cryptogenic species for the Caribbean

Marine Pollution Bulletin, Год журнала: 2023, Номер 188, С. 114649 - 114649

Little is known about early coral settlement on shipwrecks with regard to their species and size compositions. Hurricanes in the Caribbean have a long history of sinking ships but link new understudied. In 2017, Hurricane Irma caused over 300 vessels coastal waters Saint Martin, eastern Caribbean. 2021, was studied one them, which included two native, non-native, cryptogenic species. The corals were smaller than 8 cm diameter. invasive Tubastraea coccinea most abundant scleractinian predominantly represented by juveniles. A species, Stragulum bicolor, for Caribbean, common octocoral. Because they can be harmful environment, should monitored frequently occurrence non-native especially when are only few years old.

One step ahead of sea anemone invasions with ecological niche modeling: potential distributions and niche dynamics of three successful invasive species

Marine Ecology Progress Series, Год журнала: 2022, Номер 690, С. 83 - 95

Опубликована: Март 28, 2022

Established non-native sea anemone populations can affect the native community through multiple mechanisms, including predation and competition. The conservation of invaded communities is therefore great concern, spatially explicit information essential for prevention or early detection introductions. Here, we used ecological niche modeling to (1) predict areas with invasion risk 3 successful widespread invasive species ( Diadumene lineata , Exaiptasia diaphana Nematostella vectensis ); (2) determine stage current occurrences; (3) test climatic match hypothesis success by assessing their environmental dynamics. Our results bring new insights process anemones, which relevant considering scarcity monitoring efforts, issues associated detection, potential effects they generate on communities. First, provide distributions that could help detect on. Second, confirm a strong pattern establishment. Finally, demonstrate these has mainly occurred in conditions similar those from respective ranges (i.e. match, conservatism).
