Abstract

Marine protected areas are an important tool to recover and protect coral reef biodiversity. Connected networks of individual marine protected areas enhance system-wide resilience and persistence via the exchange of individuals, supporting greater population sizes and functional genetic diversity. Conservation area networks are typically designed with a systematic spatial planning process. New perspectives and emerging methods enable the long-standing goal to incorporate connectivity as a conservation feature with the aim of maximizing larval flow within the network. Additionally, there is growing recognition that protected area networks that support adaptive evolutionary change make the long-term survival of coral reefs more likely. Genetic data and evolutionary principles can feed into the planning process by providing measures of dispersal connectivity and adaptation potential. Here, we review genetic and genomic approaches to estimate dispersal connectivity and the geography of adaptation for corals. We outline key conservation objectives that can be informed by genetic data, propose surrogates for connectivity and adaptation features, and recommend future pathways to improve the uptake of genetic information for reef conservation such that management actions that prioritize connectivity and adaptation can be realized.
