Summary Marine invertebrates vary in their reproductive strategies, from brooding until settlement to broadcast spawning of gametes and from direct developing (non-feeding) forms to long-lived larval stages. Regardless of strategy, recruitment rates into existing or new habitat can determine survival of a species and adaptation to new conditions. Recruitment can be measured as successful settling or juvenile stages into appropriate habitat for the juvenile and/or adult form. General Information Sustainability Goal Goal 5. Protect and enhance environmental conditions by improving watershed, floodplain, and aquatic condition and processes. Domain Ecosystem Health = The condition of natural system, including terrestrial systems interacting with aquatic systems through runoff pathways.
