Marine protected areas (MPAs) are a cornerstone of marine conservation. Globally, the number and coverage of MPAs are increasing, but MPA implementation lags in many human-dominated regions. In areas with intense competition for space and resources, evaluation of the effects of MPAs is crucial to inform decisions. In the human-dominated Mediterranean Sea, fully protected areas occupy only 0.04% of its surface. We evaluated the impacts of full and partial protection on biomass and density of fish assemblages, some commercially important fishes, and sea urchins in 24 Mediterranean MPAs. We explored the relationships between the level of protection and MPA size, age, and enforcement. Results revealed significant positive effects of protection for fisheries target species and negative effects for urchins as their predators benefited from protection. Full protection provided stronger effects than partial protection. Benefits of full protection for fish biomass were only correlated with the level of MPA enforcement; fish density was higher in older, better enforced, and —interestingly— smaller MPAs. Our finding that even small, well-enforced, fully protected areas can have significant ecological effects is encouraging for “crowded” marine environments. However, more data are needed to evaluate sufficient MPA sizes for protecting populations of species with varying mobility levels.

“…Local impacts, such as urbanization (Scherner et al, 2013;Portugal et al, 2016;Cruz et al, 2018), fisheries (Floros et al, 2013;Giglio et al, 2017), contamination (Cruz et al, 2018;Porter et al, 2018), and dredging (Fisher et al, 2019) degrade coastal turbid-zone and high-latitude marginal reefs. The vulnerability of marginal reefs to local and regional impacts is partly explained by their unique ecological dynamics (Fig.…”

“…Additionally, rises in temperature lead to a higher frequency of tropical storms and alterations of marine nutrient cycling with large potential consequences for natural species assemblies (Behrenfeld, 2011; Doney et al, 2012). In face of these multiple threats, frequent and accurate monitoring of fish communities and general aquatic biodiversity is urgently required to implement adaptive management approaches and respond to early warning systems before the onset of catastrophic break‐downs (Clements et al, 2017; Floros et al, 2013).…”

The coastline of Sub‐Saharan Africa hosts highly diverse fish communities of great conservation value, which are also key resources for local livelihoods. However, many costal ecosystems are threatened by overexploitation and their conservation state is frequently unknown due to their vast spatial extent and limited monitoring budgets. Here, we evaluated the potential of citizen science‐based eDNA surveys to alleviate such chronic data deficiencies and assessed fish communities in Mozambique using two 12S metabarcoding primer sets. Samples were either collected by scientific personnel or trained community members and results from the two metabarcoding primers were combined using a new data merging approach. Irrespective of the background of sampling personnel, a high average fish species richness was recorded (38 ± 20 OTUs per sample). Individual sections of the coastline largely differed in the occurrence of threatened and commercially important species, highlighting the need for regionally differentiated management strategies. A detailed comparison of the two applied primer sets revealed an important trade‐off in primer choice with MiFish primers amplifying a higher number of species but Riaz primers performing better in the detection of threatened fish species. This trade‐off could be partly resolved by applying our new data‐merging approach, which was especially designed to increase the robustness of multiprimer assessments in regions with poor reference libraries. Overall, our study provides encouraging results but also highlights that eDNA‐based monitoring will require further improvements of, for example, reference databases and local analytical infrastructure to facilitate routine applications in Sub‐Saharan Africa.
