Distribution and abundance of Donax serra Röding

1986-11-28  Donax serra Röding is unusual among intertidal dwelling Donax species in that it does not undergo tidal migrations. We examined the distribution and abundance of the D. serra population along a 200-m section of exposed sandy beach throughout a 96-day period.D. serra was shown to exhibit a semilunar pattern of movement corresponding to the spring-neap tidal cycle.

Outbreak densities of the coral predator Drupella in ...

2018-11-2  Outbreaks of coral predators are defined as increases (often rapid) in their abundance above threshold densities that can be sustained by local coral assemblages, which in turn depends on the abundance and turnover of coral prey. To investigate the outbreak densities of the corallivorous gastropod Drupella Gypsumus, we conducted both in situ feeding and coral growth experiments at Mandu
