able to survive and develop into adults but not reproduce inside the lagoon, and
individuals of colonizing species must compete with lagoon species for resources.
In summary, lagoon species assemblages are the result of the continuous or
seasonal interaction between native lagoon inhabitants (physiologically adapted to
stressed and changing environments, and with reproductive capability in such con-
ditions), and sporadic, accidental, or periodic colonization. Some species also adapt
to the lagoon environment but are incapable of reproduction, while others survive,
reproduce, and become established but only under favorable conditions. In both
cases such species are at a disadvantage in competition with native lagoon species
because they spend most of their energy budget in physiological adaptations. How-
ever, from the point of view of the species population stability, the resulting high
mortality rates and loss of reproduction could be compensated for by high recruit-
ment rates from larval stages or from adults from the open coastal sea.
