Overview



With regards to population dynamics, information on species such as L. medusa that inhabit both estuarine and marine soft-sediment communities is not readily available. This is compounded for infaunal species that are large, less abundant and subsequently difficult to sample (Schaffner 1990). However the presence of such species is important for community dynamics as they are capable of contributing substantial levels of biomass, heavily impact sediment structure and biogeochemistry, with flow on affects that can influence the distribution and abundance of smaller organisms.
