The study and implementation of no-take marine reserves have increased rapidly over the past decade, providing ample data on the biological effects of reserve protection for a wide range of geographic locations and organisms. The plethora of new studies affords the opportunity to re- evaluate previous findings and address formerly unanswered questions with extensive data synthe- ses. Our results show, on average, positive effects of reserve protection on the biomass, numerical density, species… Expand

Studies of no-take marine reserves: Methods for differentiating reserve and habitat effects
TLDR
Robust studies, utilising methods within BACI designs, are needed to accurately differentiate NTMR from habitat effects and permit managers to more accurately assess the benefits of NTMRs. Expand
The Role of Pre-Existing Disturbances in the Effect of Marine Reserves on Coastal Ecosystems: A Modelling Approach
TLDR
An end-to-end ecosystem model is used to explore responses over 30 years to coastal no-take reserves covering up to 6% of the continental shelf and slope off the coast of New South Wales to illustrate the need to carefully align the design and implementation of marine reserves with policy and management objectives. Expand
Ecological effects of marine reserves in Latin America and the Caribbean
TLDR
On average, the total biomass, density and body size of species increased inside marine reserves but species richness did not, and a stronger focus on both target species and the suite of other interacting species will allow better estimates of the community-wide effects of protection. Expand
Temperate marine reserves: global ecological effects and guidelines for future networks
TLDR
Higher density, biomass, and species richness in temperate marine reserves compared to adjacent exploited areas, however, there was considerable heterogeneity in magnitude of effect among reserves, variability which was largely unexplained by species or reserve characteristics. Expand
Variation in Responses of Fishes across Multiple Reserves within a Network of Marine Protected Areas in Temperate Waters
TLDR
Surveys of fishes for seven years in and near newly created marine protected areas (MPAs) in central California showed that initially most MPAs contained more and larger fishes than associated reference sites, likely due to differences in habitat quality. Expand
Can marine reserves restore lost ecosystem functioning? A global synthesis.
TLDR
Meta-analyses suggest that modern levels of predation in the coastal oceans may currently only be a fraction of the baseline prior to human exploitation, and highlights the capacity of MPAs to restore a critical ecosystem function such as predation, which mediates energy flows and community assembly within natural systems. Expand
Increased Disease Calls for a Cost-Benefits Review of Marine Reserves
TLDR
The health of lobster populations in the UK’s Marine Conservation Zone (MCZ) at Lundy Island is investigated and ostensibly positive effects such as increased lobster abundance and size are shown within the No-Take Zone; however, apparent negative effects are also demonstrated. Expand
Massive differential site-specific and species-specific responses of temperate reef fishes to marine reserve protection
TLDR
This study highlights both the importance of site-specific effects and the method of analysis when quantifying MR effects to correctly attribute observed differences among sites to MR effects or to site- specific habitat quality effects. Expand
Effects of ecosystem protection on scallop populations within a community-led temperate marine reserve
TLDR
Results suggest that structurally complex habitats growing within the reserve have substantially increased spat settlement and/or survival, consistent with the hypothesis that marine reserves can encourage the recovery of seafloor habitats, which, in turn, can benefit populations of commercially exploited species. Expand
Conservation benefits of a network of marine reserves and partially protected areas
TLDR
Examination of changes within a network of “no take” marine reserves relative to partially protected “take” areas after 5 years of operation shows that some targeted species including red morwong and abalone were more abundant in marine reserves than elsewhere. Expand

Biological responses in marine no-take reserves versus partially protected areas
Marine Protected Areas (MPAs) are a common tool for conserving and managing marine and coastal ecosystems. MPAs encompass a range of protection levels, from fully protected no-take reserves toExpand

Marine reserves are a spatial approach to marine management and conservation aimed at protecting and restoring multispecies assemblages and the structure and function of marine ecosystems. We usedExpand
Community-wide effects of marine reserves in the Mediterranean Sea
TLDR
Non-linearities in the community-wide effect of reserves suggest that caution is needed in simplistically treating reserves and unprotected areas as 2 experimental treatments in ecological studies, and that the assemblage-wide response to protection at the species level may be spatially idiosyncratic. Expand
THE IMPACT OF MARINE RESERVES: DO RESERVES WORK AND DOES RESERVE SIZE MATTER?
TLDR
The empirical work and the theoretical literature are reviewed to assess the impacts of marine reserves on several biological measures (density, biomass, size of organisms, and diversity), paying particular attention to the role reserve size has in determining those impacts. Expand
MARINE RESERVES EXPLOIT POPULATION STRUCTURE AND LIFE HISTORY IN POTENTIALLY IMPROVING FISHERIES YIELDS
TLDR
Model results suggest that reserve networks may have the potential to enhance fishery yields under a surprisingly large number of circumstances and are predicted to be greatest, and at times substantial, in species exhibiting postdispersal density depen- dence. Expand
Marine reserves have rapid and lasting effects
Marine reserves are becoming a popular tool for marine conservation and resource management worldwide. In the past, reserves have been created with little understanding of how they actually affectExpand
Changes in community structure in temperate marine reserves
TLDR
Changes in community structure, which have persisted since at least 1994, demonstrate not only higher trophic complexity than anticipated in Australasian ecosystems but also increased primary and secondary productivity in marine reserves as a consequence of protection. Expand
Continuing trophic cascade effects after 25 years of no-take marine reserve protection
TLDR
Long-term changes in benthic communities in the Leigh reserve and the stability of differences between reserve and non-reserve sites over time are consistent with gradual declines in urchin densities due to increased pre- dation on urchins, thus providing further evidence for a trophic cascade in this system. Expand
Marine reserves: size and age do matter.
TLDR
Using 58 datasets from 19 European marine reserves, it is shown that reserve size and age do matter: Increasing the size of the no-take zone increases the density of commercial fishes within the reserve compared with outside; whereas thesize of the buffer zone has the opposite effect. Expand
Conservation benefits of marine reserves for fish populations
TLDR
It is confirmed that marine reserves benefit fish populations and the need for monitoring prior to reserve establishment is highlighted to provide more accurate, habitat-controlled studies of the effects of marine reserves on fish populations. Expand
