| |
| − | To follow the process of colonization and succession of life on wood and to study the process of wood degradation we deployed our custom-designed BiOlogical Recruitment Grids (BORGs) last summer. The three sites we chose were 1) the canal Lera of the Secovlje Salina Nature Park (http://www.kpss.si/en/intro ), 2) the shallow subtidal area of the Strunjan Landscape Park (https://www.naravniparkislovenije.si/…/strunjan-landscape-p…), and 3) in front of the Marine Biology Station in Piran (https://www.nib.si/mbp/en/).

| |

While shipworms live in symbiosis with wood degrading, nitrogen fixing bacteria, some isopods and amphipods can digest wood without the help of symbionts. After sampling the wooden cubes we took pictures of all surfaces. The surface of this wooden plate was covered by hydozoans and algae. Only from the inside the occurrence of many shipworms became apparent.</blockquote>
