“…The maximum length measured at Salas y Gómez was 35 cm, which is 40% greater than the maximum length reported for the species before this expedition (25 cm; Holthuis, ). This species has been exploited intensely and consumed at restaurants on Easter Island (Boyko, ) but was not observed around Easter Island during the present surveys. In contrast, at Salas y Gómez several individuals were observed during daylight, in a cave, and in the open, at between 16 and 35 m depth.…”

An expedition to Salas y Gómez and Easter islands was conducted to develop a comprehensive baseline of the nearshore marine ecosystem, to survey seamounts of the recently created Motu Motiro Hiva Marine Park (MMHMP) – a no‐take marine reserve of 150 000 km2 – and to compare these results with Easter Island where the marine ecosystem is similar but has no marine protection.Live coral cover was surprisingly high at both Easter Island (53%) and Salas y Gómez (44%), especially considering their sub‐tropical location, high wave energy environments, and geographic isolation.Endemic and regionally‐endemic species comprised 77% of the fish abundance at Easter Island and 73% at Salas y Gómez. Fish biomass at Salas y Gómez was relatively high (1.2 t ha‐1) and included a large proportion of apex predators (43%), whereas at Easter Island it was almost three times lower (0.45 t ha‐1) with large predators accounting for less than 2% of the biomass, despite good habitat quality.The large cohort of small sharks and the absence of larger sharks at Salas y Gómez suggest mesopredator release consistent with recent shark fishing. The fish fauna at the seamounts between Easter Island and Salas y Gómez, outside of MMHMP, harboured 46% endemic species, including a new species of damselfish (Chromis sp. nov.) and probably a new species of Chimaera (Hydrolagus). Numerous seamounts adjacent to Salas y Gómez are currently not included in the MMHMP.This expedition highlights the high biodiversity value of this remote part of the Pacific owing to the uniqueness (endemicity) of the fauna, large apex predator biomass, and geographic isolation.Copyright © 2013 John Wiley & Sons, Ltd.

“…The ecosystems of Hawai'i and Rapa Nui contain some of the highest rates of endemism and have fostered and sustained similarly unique cultural histories (Boyko, ; Friedlander, DeMartini, Wedding, & Clark, ; Glynn et al, ; Hurles, Matisoo‐Smith, Gray, & Penny, ; Kane, Kosaki, & Wagner, ; Kay & Palumbi, ; Kirch, ; Kosaki et al, ; Maragos et al, ; Randall, ; Randall & Cea, ). In the Northwestern Hawaiian Islands, a number of stone images (ki'i) found on Nihoa and Mokumanamana are described in early historical accounts of Hawaiian culture (Emory, ; Kikiloi, , ).…”

The world's oceans are often perceived as barriers that separate countries. To counter these divisions and improve protection of ocean resources, marine protected area (MPA) managers have formed alliances that bridge jurisdictional boundaries to share strategies and resources with other protected areas. The National Oceanic and Atmospheric Administration's Office of National Marine Sanctuaries has embraced this sister site approach to connect MPA management based on ecological and cultural links. Designed to strengthen the management of ecologically and culturally connected areas, these relationships between protected areas serve as catalysts for effective stewardship of the ocean's biological resources and show the important benefits of transnational cooperation. This paper summarizes the lessons from over a decade of sister site partnerships, including case studies from Stellwagen Bank National Marine Sanctuary and four sites in the Caribbean working together to protect a shared population of humpback whales; the Gulf of Mexico Sister Site Network being developed by the USA, Mexico, and Cuba; Papahānaumokuākea Marine National Monument and Rapa Nui in Chile; and broader collaboration among MPAs in the USA and Chile on the Pacific coast.

“…With this new record, the number of benthic polychaete species reported for the littoral zone of Easter Island increases to approximately 71 (Kohn & Lloyd, 1973b;Cañete, 1989Cañete, , 1997, and the number of Syllidae family representatives registered to date at the island increases to 13. Finally, it is important to stress the urgent need to know the current status of the benthic biodiversity at Easter Island, particularly as the government is discussing if the island should be part of a large park for protecting marine biodiversity (Boyko 2003, Cañete, 2016. Chilean oceanic islands have received little attention, both scientifically and in terms of conservation.…”

ABSTRACT. This study is the first to report the presence of the polychaete Parasphaerosyllis indica Monro, 1937 (Syllidae) near the coastal areas of Easter Island (27°10'S, 109°20'W). This species has a circumtropical geographic distribution and low abundance and frequency rates in relation to other Syllidae species (12) collected from Easter Island. With P. indica, the benthic polychaetes biodiversity of Easter Island is now 71 species.
