The influence of substrate type on sexual reproduction of the bryozoan Cribrilina annulata (Gymnolaemata, Cheilostomata): A case study from Arctic seas
Abstract This study compared the fecundity of the colonies of the cheilostome bryozoan Cribrilina annulata (Fabricius, 1870) collected from two differing substrates Á shingles and the algae Odonthalia dentata (Linnaeus) Lyngbye, 1819 Á in the White and the Barents Seas. Almost all colonies growing o...
