fine. Abstract: Marine protected areas (MPAs) have become critical
components of fisheries management programs worldwide. Here, we aim to
standardize conclusions regarding MPA performance throughout the
Philippines using a ‘reef-wide’ meta-analysis. This analysis uses pooled
visual census data from 39 matched pairs of MPAs and fished reefs surveyed
twice over a mean period of 3 yr, allowing for the comparison of abundance
and demographic structure of fishes across both protected and fished areas
over time. The meta-analysis revealed that (1) although fish density was
higher inside MPAs within individual sampling periods, reef-wide fish
density generally either increased or remained stable over time, and (2)
reef-wide increases in large-bodied fish were evident between survey
periods, indicating positive demographic shifts within both MPAs and
adjacent areas. These results suggest that, over relatively few years of
protection, MPAs in the Philippines are able to promote beneficial shifts
in fish population structure throughout entire reef systems rather than
simply maintaining stable populations within their borders. The reef-wide
framework of MPA assessment demonstrated in this study presents the
advantages of including adjacent fisheries as integrated components when
quantifying MPA performance, revealing trends that are indistinguishable
when using spatial comparisons between MPAs and fished reefs. About the
Speaker: Dr. Robert Fidler is a fisheries biologist, with a focus on
coral-reef ecosystems. His research examines the use of marine reserves or
marine protected areas (MPAs) in fisheries management and coral-reef
conservation. Specifically, his work examines the ability of MPAs to
promote phenotypic recovery from fisheries-induced evolution in exploited
populations using both large-scale meta-analysis and empirical
investigations. Dr. Fidler received a B.S. from the University of Virginia,
an M.S. and Ph.D. from the Florida Institute of Technology, and was a
2014-2015 U.S. Student Fulbright Scholar in the Philippines. Subscribe to
