summary - Volume 18, Issue 3 (2023)
The new issue of Aquatic Invasions
includes seven research articles that report the presence and distribution of new invasive species.
A study reported the presence of the introduced bryozoan Watersipora subatra
in the French Mediterranean Sea. The study also reveals pervasive misidentifications of Watersipora
species in genetic reference databases, leading to errors in recent studies.
The introduction of the Harris mud crab (Rhithropanopeus harrisii
), a novel predator, has contributed to the decline of the bladder wrack (Fucus vesiculosus
) in the Archipelago Sea, a key species for littoral communities.
Smooth cordgrass (Spartina alterniflora
Loisel.) colonised tidal flats on the west coast of Korea and occupied a wider absolute intertidal range at the megatidal vs mesotidal region, but its lower limit did not extend below Mean Sea Level under megatidal conditions.
A study examines the distribution patterns of three pseudo-cryptic Ammonia species
, A. aberdoveyensis
, A. confertitesta
, and A. veneta
, along the French coasts of the English Channel.
Lower average population density of Rangia cuneata
in the Szczecin Lagoon was found, with the highest density found in sites with more silt and less sand. The species' invasive potential and rapid colonization make monitoring its migration patterns crucial.
A study using 455 global records and five biological variables predicted the distribution of red drum (Sciaenops ocellatus
) in Chinese waters and future distribution under two climate change scenarios. The model showed that average temperature was the most influential environmental variable.
The new assessment of invasive suckermouth armored catfish Pterygoplichthys spp
. in the Da Rang River estuary showed that armoured catfish can move in brackish waters but avoid high salinity water, supporting the hypothesis of invasion through estuaries and coastlines.
