The age information of commercially important species is crucial in fisheries management. Age various fish and molluscan has routinely been determined by counting annual growth bands deposited within the hard structures. In crustaceans such structures were previously believed to be lost replaced due molting. However, a technique was recently developed use structure retained through molting as an indicator. present study, applicability novel investigated for four crustacean collected from...
A collective understanding of economic impacts and in particular monetary costs biological invasions is lacking for the Nordic region. This paper synthesizes findings from literature on countries together with expert elicitation. The analysis cost data has been made possible through InvaCost database, a globally open repository that allows use temporal, spatial, taxonomic descriptors facilitating better how are distributed. total reported invasive species across were estimated at $8.35...
Non-indigenous species (NIS) represent a serious problem worldwide, where ascidians are one of the most important taxa.However, little has been done to document non-indigenous in Iceland, and over past decade only two had recorded prior present study, Ciona intestinalis 2007 Botryllus schlosseri 2011.To increase knowledge this taxon, extensive sampling was carried out shallow waters around during summer 2018, ports on ropes long-line mussel aquaculture.In total, eleven were identified, four...
Species breeding at high latitudes face a significant challenge of surviving the winter. Such conditions are particularly severe for diurnal marine endotherms such as seabirds. A critical question is therefore what behavioural strategies species adopt to maximise survival probability. We tested 3 hypotheses: (1) they migrate lower exploit longer day length (‘sun-chasing’), (2) forage night (‘night-feeding’), or (3) target high-quality food patches minimise foraging time (‘feasting’). studied...
A study on the origin of a newly colonized population Atlantic rock crab, Cancer irroratus Say, 1817, in Icelandic coastal waters based mtDNA variation revealed challenging problem. Variation mitochondrial cytochrome oxidase subunit I gene (COI), which has played pivotal role phylogeographic studies, was assessed. Most individuals were found to carry two or more different genetic fragments and several ambiguous sites, with segregating nucleotides, both within samples from North America...

Global shipping facilitates the introduction of fouling organisms to new geographic areas. The increase in maritime transport recent decades has led unprecedented development, where marine coastal waters have become one most invaded habitats around globe. Among successful invaders are ascidians. Despite and oceanographic isolation Iceland, it is far from being excluded as a recipient region. Ascidians successfully been able establish stable populations Iceland that slowly expanding SW Here...
The Atlantic rock crab Cancer irroratus was discovered in Icelandic waters August 2006 and spread rapidly along the coastline. species has reproduced successfully Iceland, there have been strong indications that C. become common on soft-bottom coastal habitats south-western Iceland. To be able to evaluate effect of such non-indigenous ecosystem, population density estimates are required. In years 2011 2014, a mark-recapture study carried out small inlet Kollafjörður fjord, total, 6475 were...
Abstract The Atlantic rock crab (Cancer irroratus) was first found in Icelandic waters 2006. Since then, the species has dispersed rapidly and is currently clockwise from southwest coast of Iceland to east, corresponding >70% coastline. Here, we present a monitoring study on this non-indigenous 2007 2019. shows that now most abundant brachyuran soft substrate bottoms Southwest Iceland, both as adults planktonic larvae, indicating it outcompeting its rival native species, European...
In recent years the number of non-indigenous marine species has been increasing in Icelandic waters.In May 2019, a razor shell (Ensis sp.) was found for first time Iceland.Since then, living and empty shells have discovered at several locations Southwest Iceland.Upon morphological examination, specimens were thought to belong either Ensis leei or terranovensis, both native east coast North America.Molecular analysis, using COI 16S rRNA markers, showed that latter species.Native populations...
Context Botryllus schlosseri and Diplosoma listerianum are spreading along the south-western coast of Iceland. Both species non-indigenous originated from temperate zone. In some geographic regions, these have been associated with negative ecological economic impacts. The proliferation colonial tunicates in newly colonised areas will benefit projected warming sea-surface temperatures. Aims Owing to influence temperature physiological processes marine invertebrates, determination temporal...
Abstract Egg masses from an unknown mollusc have been found in South-West Iceland since 2020, but it was not until September 2023 that the adult organism collected. Morphological analysis of both adults and egg pointed towards identification species as Melanochlamys diomedea . This further confirmed through DNA analyses using COI, H3, 16S rRNA markers, which established presence a new non-indigenous North Atlantic. Members genus predominantly Indo-Pacific basin Pacific Ocean, with only one...
Rhizoclonium riparium is a cryptogenic macroalga that freely inhabits fresh, sea and brackish waters able to compete in variety of habitats. In the summers 2018 2019, this alga was found form huge filamentous mats, covering all rocks, down depth 3 m harbour Reyðarfjörður, east Iceland. The species taxonomy confirmed by molecular data. Here, we report invasive behaviour which may represent pool source for R. dispersal, as hull fouling most likely vector spread species.
