“…For example, the goal of maintaining maximum biological diversity is implicit in the entrenched debate on the design of nature reserves (e.g. Diamond, 1975;Simberloff & Abele, 1976Higgs & Usher, 1980;Diamond & May, 1981;Higgs, 1981;Margules et al, 1982). But that debate is concerned mainly with ecological processes within reserves, so even reliable reserve design principles will not preserve maximum diversity if maximum diversity has not been set aside in the first place.…”

“…Diamond [14] stated that a Single Large (SL) reserve was preferred over Several Small (SS) reserves (keeping total area equal) for multispecies conservation. Subsequent theoretical (Higgs and Usher [18]) and empirical (Gilpin and Diamond [16]) work, however, suggested that a large number of sites covers more species than a single large one, given that total reserve area is constant. According to our results, it appears that having multiple small MPAs may be preferable than a single large one: Our results show that the biomass of fish increases when the number of reserves increases and the level of catch at equilibrium in the SS scenario is larger than under SL scenario.…”

“…As symmetric movement rates for boats were assumed, β 3,1 = β 1,3 and, therefore, E 1 and E 3 must be equal at equilibrium and as a consequence, taking into account (13) and (14), we obtain for all i We substitute the fast equilibria (A.4) into the complete model (15,16,17,18), and add the (2L) fish stock and the L fishing effort equations. After some algebra, one obtains the following system of two equations governing the total fish stock and fishing effort variables at the slow time scale, which we call the aggregated model:…”
