[en] Background
The seagrass Posidonia oceanica L. Delile, commonly known as Neptune grass, is an endemic species of the Mediterranean Sea. It hosts a distinctive and diverse epiphytic community, dominated by various macroalgal and animal organisms. Mediterranean bryozoans have been extensively studied but quantitative data assessing temporal and spatial variability have rarely been documented. In Lepoint et al. (2014a, b) occurrence and abundance data of epiphytic bryozoan communities on leaves of P. oceanica inhabiting the Revellata Bay (Corsica, Mediterranean Sea) were reported and trophic ecology of Electra posidoniae Gautier assessed.
New information
Here, we provide metadata information on data set discussed in Lepoint et al. 2014a and published on the GBIF portal as a sampling-event data set: http://ipt.biodiversity.be/resource?r=ulg_bryozoa&v=1.0).
The data set, compared to Lepoint et al. 2014a, is enriched by data concerning species settled on Posidonia scales (dead petiole of Posidonia leaves, remaining after limb abscission).

General description of the dataset
The data set is a sample-based data set (n = 103 sampling events), recording occurrence (n = 1234) and abundance of cheilostome Bryozoa (n = 6488 counted colonies) settled as epiphytes on leaves and scales of the seagrass P. oceanica. Sampling encompasses an entire annual cycle (from November 2002 to December 2003) (n = 5 sampling seasons) and 6 sampling depths (7, 10, 15, 20, 25, 30 m). The data set package is composed of two data files: the former describing sampling events the latter reporting occurrence and abundance of bryozoan colonies.
