siltation or low salinity?

[Hoeksema, B.W.]

In reply to the message of Dr.R. Jayabaskaran:

In Indonesia, relatively dense populations of Pseudosiderastrea tayami Yabe
and Sugiyama, 1935
may co-occur with abundant Oulastrea crispata (Lamarck, 1816) corals.
This this is likely the case on reefs near river outlets with much siltation
(e.g. in Jakarta Bay, off Jakarta, and in the Makassar Strait off Makassar).
However, there are also reefs with freshwater inflow (e.g. at Tulamben,
Bali) where both species can be found in very clear water. Siltation may not
be the key-factor determining the occurrence of these species, but low
salinity.
