|Reproduction & dispersal|
|The topic of reproduction & dispersal is divided into a section on dispersal, considered here, and sections on LIFE CYCLE, MATE SELECTION COPULATION & FERTILISATION, and BROOD CHAMBER, considered in other sections.|
Research study 1
Dispersal in benthic amphipods is mostly limited to swimming and crawling and, for small individuals, floating, with “rafting” on drifting algal mats also occurring. Counts of invertebrates in drift-algae samples originating from mudflats in San Juan Island, Washington in summer show that amphipods comprise more than 50% of the total number. The author speculates that the geographic distribution of brooding species of invertebrates may generally be correlated with rafting opportunities.
NOTE of 1287 invertebrates present in 24 floating algal mats (consisting mainly of the green algae Ulva and Monostroma), amphipods represent 656. Other invertebrates present are taneids, shrimps, polychaetes, gastropods, and other small species
