Competition, predation, and facilitation mechanisms are the major drivers of
biodiversity and community structure in marine benthic ecosystems. Habitat
complexity is a determining factor of faunal richness and biodiversity in these
communities. The structure of marine animal forests is originated by living threedimensional
aggregations of modular animals. The persistence of these systems
through time relies on the growth of existing individuals and the recruitment of
new ones. Therefore, the present and future health of these valuable ecosystems
may depend on the reproductive success of a few vulnerable species which might
often be accomplished only under strict or very narrow conditions. Reproductive
patterns of ecosystem engineers play a crucial role in determining the structure,
function, and distribution of all kinds of marine animal forests at different scales.
The reproductive strategies of these habitat-forming species may vary considerably.
Though most ecosystem-engineering species are, to some extent, able to
reproduce asexually, their sexual reproductive strategies are diverse. Dispersal
ability strategies are selected as an adaptation to spatial heterogeneity and habitat
stability and are important factors for the resilience of the ecosystems. Dispersal
traits are essential for both small-scale population structuring and connectivity
among distant populations. Disturbed habitats may be promptly recolonized by
species with long-distance dispersal capability, but recolonization by species with
low dispersal capacity might limit the full restoration of a disturbed ecosystem,
especially in fragmented habitats with reduced connectivity between patches.
Due to the lack of knowledge on the reproductive cycles of many marine
invertebrates, the response of animal forest ecosystems to global change is, in
general, unpredictable.
