Ulva californica Wille

3.2 Ulva californica Wille

We report the presence of Ulva californica Wille ( Figure 4 View Figure 4 ) in the most internal sites of the Lagoon of Venice, ST01 and

ST02. This species was first reported in 2012 in the historic centre of Venice by Wolf et al. (2012).

U. californica was first described in 1899 from La Jolla, California ( Collins et al. 1899). Opinions about the original range of the species are very different ( Wei et al. 2022), from a distribution limited to North America ( Scagel 1989; Wolf et al. 2012) or wider, including European temperate coasts ( Loughnane et al. 2008). New and numerous reports of this species have been made in different biogeographical areas through molecular data, including Japan ( Kawai et al. 2007), New Zealand ( Heesch et al. 2009), Italy ( Wolf et al. 2012) and Australia ( Kirkendale et al. 2013).
