Ecological ImpactCompetition
Bugula neritina was one of several invasive fouling species which showed increased growth (zooid number) at temperatures 3.5 and 4.5⁰C above the ambient temperature in Bodega Harbor (13.5⁰C), while the native colonial tunicate Distaplia occidentalis showed reduced survival (Sorte et al. 2010). Bugula neritina was one of a group of seven non-native species in Bodega Harbor, most of which were rare or absent in 1970-1971, but were among the eight most abundant species in 2006. Spawning periods and abundance of species in this group appeared to be favored by a 1⁰C increase in average temperatures at this site over a 30-year period (Sorte and Stachowicz 2011).
