The population dynamics and bteeding biology of Idotea baltica, I. chelipes and I. granulosa wete studied in the littoral belts of two northern Baltic rocky shore habitats. Population sizes are largest in the aurumn, after occupation of the Fucus belt by a new Idotea generation from the belt of filamentous algae. Two periods of dectease in the population density, one in late autumn and another

Baltic Sea life-history strategies adaptation phylogeography ecological niche modelling climate change: Abstract: The three marine isopods of the genus Idotea: I. balthica, I. chelipes and I. granulosa have an important functional role as meso-grazers in the Baltic food web.

We embedded fluorescent microplastics in artificial agarose-based food and offered the food to marine isopods, Idotea emarginata.

Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts.

For example, Idotea pelagica is found in the lower intertidal and shallow subtidal on exposed rocky reefs and is replaced in less exposed areas by I. granulosa which in turn is replaced by I. chelipes on sheltered, estuarine shores (Naylor, 1955). Description Idotea granulosa has an elongated body that is oval in shape, sharply narrowing posteriorly and dorsoventrally flattened. The antennae are less than one-fifth of the overall body length. Males are 5-20 mm in length, where females are 6-13 mm in length.

Idotea densities were significantly higher and mean body size significantly smaller on Corallina than the other algal species. Isopods were significantly larger on Fucus . There was no significant difference in base colour frequencies between shores but there was a positive association between the brown base colour and Corallina and the green colour and Fucus .

Att vissa plantor är hårt betade och andra inte kan bero på att de innehåller mer kväve eller mindre florotanniner som gör dem mindre aptitliga för havsgråsuggorna. Anpassning till Östersjön - fallet med gråsuggesläktet Idotea Tre närbesläktade arter av det ursprungligen marina släktet Idotea har lyckats etablera sig i det unga brackvattenhavet Östersjön. många små djur bl.a. flera invertebrater. En av dessa invertebrater är Idotea baltica. I Östersjön förekommer F. radicans till största delen från Öregrund och norrut i Bottenhavet.

Species biology: The isopod Idotea baltica is an ecosystem engineer which increases productivity of seagrass beds (Zostera) by reducing epiphytes, and a documented controlling influence on the macroalgae Fucus vesiculosus. Idotea densities were significantly higher and mean body size significantly smaller on Corallina than the other algal species. Isopods were significantly larger on Fucus .

Plastic pollution is an emerging global threat for marine wildlife. Many species of birds, reptiles, and fishes are directly impaired by plastics as they can get entangled in ropes and drown or they can ingest plastic fragments which, in turn, may clog their stomachs and guts. Microplastics of less than 1 mm can be ingested by small invertebrates, but their fate in the digestive organs and

Antenna 1 extending beyond article 2, but not article 3 of the peduncle of antenna 2; the most distal aesthetascs as a pair. Antenna 2 flagellum not reaching the length of the peduncle (except possibly in large males which have tufts of setae on the flagellum ); usually less than 1/5 of the body Brusca (1984) regarded Idotea a cosmopolitan genus, but which is absent from the warm and tropic seas in both the Pacific and the Atlantic oceans. Most of the Idotea species are endemic and restricted to shorelines in Europe, North America or Asia. Only two species, Idotea balthica and Idotea metallica, have a Description. A dorso-ventrally flattened isopod crustacean with an elongated oblong, oval body. The body is uniformly green or brown in colour, often with white spots or longitudinal lines.
