  Insights and achievements from the Tara Pacific expedition

  The Tara Pacific program and expedition focused on coral reefs across the Pacific Ocean and used a coordinated sampling effort to address questions at multiple scales using a common suite of samples. Here, we highlight some of the Tara Pacific achievements, discussing the benefits of long-duration sea expeditions for investigating a wide array of research questions within a selected ecosystem.

  Endogenous viral elements reveal associations between a non-retroviral RNA virus and symbiotic dinoflagellate genomes

  A study part of the Tara Pacific Expedition that surveyed newly sequenced and publicly available metagenomes and genomes revealed pervasive non-retroviral dinoflagellate-infecting endogenous +ssRNA viral elements within coral symbionts.

  Diversity of the Pacific Ocean coral reef microbiome

  Using data from the Tara Pacific expedition, this study reports the biogeography and the diversity of microbiomes collected from corals, fish and plankton in 99 reefs across the Pacific Ocean. The large richness of Pacific Ocean reef microorganisms, when extrapolated to all fish and corals of the Pacific, represents the current estimated total prokaryotic diversity for the entire Earth.

  Ecology of Endozoicomonadaceae in three coral genera across the Pacific Ocean

  Bacterial symbionts of the Endozoicomonadaceae family are frequently found in marine animals but are poorly understood. Using data from the Tara Pacific expedition, this study of Endozoicomonadaceae ecology at an ocean basin-scale reveals that corals across the Pacific Ocean have different host-symbiont association strategies that are determined at the bacterial lineage level.

  Telomere DNA length regulation is influenced by seasonal temperature differences in short-lived but not in long-lived reef-building corals

  Using data from the Tara Pacific expedition, this study shows that a key driver of variation in coral telomere DNA length across the Pacific Ocean is the history of water temperature. The telomere lengths of short-lived, stress-sensitive Pocillopora colonies are more sensitive to seasonal temperature variations than those of long-lived and stress-resistant Porites colonies.

  Host transcriptomic plasticity and photosymbiotic fidelity underpin Pocillopora acclimatization across thermal regimes in the Pacific Ocean

  Using data from the Tara Pacific expedition to investigate symbiont fidelity and patterns of gene expression across a thermal gradient, this study shows that Pocillopora corals have a three-tiered strategy of thermal acclimatization that is underpinned by host–photosymbiont specificity, host transcriptomic plasticity, and differential photosymbiotic associations under extreme warming.

  Different environmental response strategies in sympatric corals from Pacific Islands

  Pocillopora species, sampled on the TARA Pacific Expedition, have greater phenotypic plasticity in response to environmental variables than Porites species, whose phenotypes were dictated by coral host genetics and past climate, according to extensive multi-biomarker analysis.

  Multi-omics determination of metabolome diversity in natural coral populations in the Pacific Ocean

  The metabolome of natural populations of Pocillopora spp., Porites spp. and Millepora cf. platyphylla coral are distinct at genus level but not within genotypes and environmental drivers influence metabolomic plasticity, suggest multi-omic analyses conducted during the Tara Pacific expedition.
