“…Many studies on species diversity of macrofaunal communities in mangrove ecosystems have been conducted globally (Morrisey et al, 2003;Pravinkumar et al, 2013;Al-Khayat et al, 2019;Vahidi et al, 2019). There have also been many studies on macrofauna diversity of mangrove forests in the Persian Gulf (Soleimanirad et al, 2011;Keshavarz et al, 2012;Safahieh et al, 2012;Vahidi et al, 2019), as well as on the diversity of Mollusca (Ghasemi et al, 2011;Kabir et al, 2014), and Polychaeta (Soleimanirad et al, 2014). Studies on functional traits of macrofauna in mangrove habitats are, however, scarce (Leung, 2015;Chen et al, 2018), and to date, such studies have not been conducted in the Persian Gulf.…”
