“…The findings indicate that both species respond rapidly to protection, with RR values >1 being recorded in the first few years after MR designation, consistent with estimates of species-specific growth rates and also density-dependent responses (e.g. Cole et al 2000, Davidson 2001a, Freeman 2008 and references therein). When analysed as a function of time, the best-fit response in all cases was linear.…”

We quantified the biological response of 2 exploited species to marine reserve (MR) protection by comparing meta-analysis results based on response ratio (RR) and Hedges' g statistics. To determine the effect of MR area and age on biological responses, a RR analysis was performed on density and size data for both species from sites inside versus outside 13 MRs. Most MRs supported a greater density of larger individuals than unprotected areas. Linear and non-linear plots of MR age and area with respect to species-specific density and size were used to quantify the trajectories of the responses. In the RR meta-analysis but not in the Hedges' g meta-analysis, MR age explained significant variation in the density and size of both species, while no effect of MR area was detected in either analysis. Comparison of the performance of RR with that of Hedges' g revealed no overall evidence of a relationship between them, probably because the RR does not include an estimate of variance, whereas the Hedges' g analysis does. While RR analysis is an appropriate alternative to Hedges' g statistic meta-analysis assessments of MR effectiveness because of its ease of use and interpretation, we recommend that future RR analyses include both an estimate of variance and a test for 'effect size'. Finally, we recommend that research be aimed at determining why different MRs produce different biological responses-that is, address why significant 'effect size' exists.

Some authors reported emigration from reserves to adjacent fished areas (Attwood and Bennett, 1994;Zeller et al, 1998;Johnson et al, 1999;Cole et al, 2000;Martell et al, 2000), while others described bidirectional movements with contrasting results (Davis and Dodrill, 1989;Rowe, 2001;Zeller et al, 2003;Kelly and MacDiarmid, 2003;Tremain et al, 2004) depending on the species and their lifestage, and on the size of the MPAs (Goñi et al, 2006). Recently, Goñi et al (2006) used a combination of tag recapture methods, fishing surveys and commercial fishery data to demonstrate the existence of a negative gradient of lobster density up to 4.5 km from the Columbretes Islands Marine Reserve.…”

SUMMARY: This study describes the results obtained by applying the Arnason Schwartz multistate mark-recapture model to eight years of data collected in and around a small no-fishing marine protected area (MPA; 4 km 2 ) in the central western Mediterranean. From 1997 to 2004, a total of 4044 specimens of Palinurus elephas (Fabr., 1787) were tagged and 317 recaptured. The most parsimonious model which best explained the data variability was that of a temporally constant rate of apparent survival and movement in each of the two strata. The absence of any temporal influence in the apparent survival rate inside the no-take area suggested that spillover and mortality are constant for each period of the study. The lower apparent survival rate in surrounding zones than inside the MPA (0.26 ± 0.04 (SE) vs 0.94 ± 0.03 (SE)) is presumed to be a function of fishing effort. A continuous movement of P. elephas across the boundary of the small MPA was also tested. This information on retention of lobsters in the MPA contributes to our understanding of the effect of introducing MPAs into a managed commercial fishery system.
