“…The importance of such constraints upon life-cycle continuity is also central to the memberhagrant hypothesis of Sinclair (1988) and Sinclair & Iles (1989). The present study thus expresses in mathematical terms parts of the memberhagrant hypothesis.…”

Many marine organisms release into the ocean planktonic larvae which must reach specific sites in order to be recruited to the next stage of their life-cycle. Solutions of the 2-dimensional advection-diffusion-mortality equation are presented which enable larval losses between release and recruitment sites to be quantified. The model assumes constant mean advection, eddy diffusivity and larval mortality. Solutions confirm that dspersal can make a significant contribution to pelagic losses and that survival is highly sensitive to the level of mean advection. The solutions have been used to examine the minimum fecundity required to overcome pelagic larval losses from a population.

“…Connectivity can be physical, for example when larvae are transported by water movements, or biological, for example, migration to exploit seasonally varying food supply. Life cycle closure theory (Sinclair 1987, Sinclair & Iles 1989 suggests that species' populations adapt their migratory and reproductive behaviour to prevailing circulation patterns (Peterson 1998).…”

Although the terms 'health' and 'healthy' are often applied to marine ecosystems and communicate information about holistic condition (e.g. as required by the Ecosystem Approach), their meaning is unclear. Ecosystems have been understood in various ways, from non-interacting populations of species to complex integrated systems. Health has been seen as a metaphor, an indicator that aggregates over system components, or a non-localized emergent system property. After a review, we define good ecosystem health as: 'the condition of a system that is self-maintaining, vigorous, resilient to externally imposed pressures, and able to sustain services to humans. It contains healthy organisms and populations, and adequate functional diversity and functional response diversity. All expected trophic levels are present and well interconnected, and there is good spatial connectivity amongst subsystems.' We equate this condition with good ecological or environmental status, e.g. as referred to by recent EU Directives. Resilience is central to health, but difficult to measure directly. Ecosystems under anthropogenic pressure are at risk of losing resilience, and thus of suffering regime shifts and loss of services. For monitoring whole ecosystems, we propose an approach based on 'trajectories in ecosystem state space', illustrated with time-series from the northwestern North Sea. Change is visualized as Euclidian distance from an arbitrary reference state. Variability about a trend in distance is used as a proxy for inverse resilience. We identify the need for institutional support for long time-series to underpin this approach, and for research to establish state space co-ordinates for systems in good health.

“…According to Sinclair & Iles (1989) in complex life histories, eggs, larvae and juveniles exhibit geographic or spatial distributions that are usually different from those characteristics of the adult phase. Many pelagic fish swim in schools which generally are size-specific, exhibiting a strong preference for similar sized individuals.…”
