November issue of BioInvasions Records is now online

Articles from 17 countries of Europe, North and South America, Asia and Africa are presented in the final 2018 release.


In this issue:

Terrestrial bioinvasions are getting our attention: agricultural invasive pests on wings (the moth Tuta absoluta) are threatening tomato crops in Benin, the maritime earwig Anisolabis maritima was recorded for the first time in South Africa, and sparrows even take trains to increase their continent-wide range of expansion!

Bad news for seas and rivers, where weeds are causing increasing concerns: everywhere you look there's Gracilaria vermiculophylla invading estuaries, there is also the new record of the highly invasive Hygtophila corymbosa for Mexico, the Brazilian elodea is reaching South-east Europe, and weeds are also invading protected areas in Italy.

Poleward to south, details on the distribution range of exotic ascidians, benthic foraminifera, gastropods are provided in this issue. Sea snails, stone crabs, the South American sun star, and the bullseye snakehead were also found outside their natural ranges. 

Warning and alerts from first records of alien molluscs (gastropods and bivalves) and fishes (the white-spotted puffer, the redlip blenny, and the variable-lined fusilier) in the Mediterranean Sea.

Aquaculture is raising concerns, as it has been indicated as the possible vector of the parasite Posthodiplostomum centrarchi.

Unfortunately, sacred rivers are also not immune to aliens, as demonstrated in our article on Ganges Delta were the non-native croaking gourami was spotted.

And when we are talking about alien species, some unexpected events may happen: such as the bloom of the upside-down jellyfish Cassiopea andromeda in Malta nine years after its first appearance.
