“…Chaenopsids, gobids, damselfishes such as S. acapulcoensis, carangids and apogonids are less abundant or considered as rare species in SBC (Arburto-Oropeza and Balart 2001). A similar situation holds for the Galapagos with a large number of species of Peruvian-Chilean origin, which were absent in our surveys (Edgar et al 2004), and with only 50% of the species shared with BH-GCH. Only 23% of the species that we found in the GCH are of Indo-Pacific or circumtropical origin, and many are shared with the other TEP regions mentioned, but these patterns vary among the mainland and offshore islands (Table 5,6).…”

“…7 Canonical correspondance analysis; mobility groups (categories) versus percentage of substrate coverage and environmental variables associated with the respective zones (zone numbers in bold, substrate codes in Table 1) of the pelagic stage of fish larvae, and substrate may play a role in shaping these differences. The species richness in the GCH is higher than in most other areas in the TEP but slightly lower than at the Galapagos and Clipperton Islands (Allen and Robertson 1997;Edgar et al 2004). The species composition (even if we exclude species that may be over-fished for human consumption) around near shore islands (e.g.…”

We compared the community structure of reef fish over different physical complexities in 12 study zones of Bahía Honda, Gulf of Chiriquí (BH-GCH), Tropical Eastern Pacific (TEP), Panama, aiming at an analysis of the importance of the physical structure provided by corals, rocks and benthic sessile organisms. This was the first region that emerged in the Isthmus of Panama; it exhibits the oldest benthic fauna and has constant conditions in terms of temperature and salinity. Two hundred and eighty-eight visual fish censuses were conducted on 48 benthic transects from February to July 2003. One hundred and twenty-six fish species of 44 families were found. Plankton feeding pomacentrids and labrids along with haemulids that feed on mobile invertebrates were the most abundant, particularly in shallow areas. Fourteen species showed size-segregations between zones, suggesting ontogenetic migrations (smaller fishes in shallow high-complexity zones, larger-sized fishes in deeper habitats). Highly mobile and site-attached genera were abundant in most shallow, wave-exposed zones particularly on exposed rocky substrates. Planktivores were the most abundant, followed by carnivores, feeders on mobile invertebrate and piscivores. Herbivores and feeders on sessile invertebrate were lower in abundance. Species richness exceeds that of any other studied region close to the mainland in the TEP and correlates with substrate diversity, increasing size-heterogeneity of holes and structural complexity. Species diversity increases with habitat complexity and benthic diversity. It seems that water current strength, tides and waves which select for swimming, play an important role in the community organization. The study region has been proposed as a refuge-centre in the TEP, where reef fishes that evolved on coral reefs have shifted their distribution onto rocky reef habitats.

“…Its zoning scheme has been recently reviewed and updated to include larger no-take zones. It consists of a mix of temperate, upwelling and tropical environments yielding a diverse assemblage of marine species with endemism ranging from 8 to 67% (Bustamante et al 2000;Hickman 2009) in five distinctive bioregions (Edgar et al 2004). Both introduced species and fishing activities pose threats to the overall health of the reserve and increased maritime traffic may lead to further introductions (Campbell et al 2015;Keith et al 2016).…”

Galápagos is one of the most pristine archipelagos in the world and its conservation relies upon research and sensible management. In recent decades both the interest in, and the needs of, the islands have increased, yet the funds and capacity for necessary research have remained limited. It has become, therefore, increasingly important to identify areas of priority research to assist decision-making in Galápagos conservation. This study identified 50 questions considered priorities for future research and management. The exercise involved the collaboration of policy makers, practitioners and researchers from more than 30 different organisations. Initially, 360 people were consulted to generate 781 questions. An established process of preworkshop voting and three rounds to reduce and reword the questions, followed by a two-day workshop, was used to produce the final 50 questions. The most common issues raised by this list of questions were human population growth, climate change and the impact of invasive alien species. These results have already been used by a range of organisations and politicians and are expected to provide the basis for future research on the islands so that its sustainability may be enhanced.

“…Echinoderms found in MFFS are considered widespread, distributed from the Gulf of California, Galapagos islands, Peru and Chile (Maluf 1988;1991;Hickman 1998;Edgar et al 2004;Solís-Marín et al 2005), being also related to the Panamanian and Galapagos region. Starfishes as Acanthaster planci, Eremicaster pacificus, E. crassus gracilis and the holothurians H. keffersteini, H. fuscocinerea, and I. horrens also occur in the Indo-Pacific region, indicating a possible connectivity between the eastern and western Pacific Oceans.…”

A systematic list of echinoderms from Malpelo Fauna and Flora Sanctuary (MFFS) was prepared, based on local sampling, literature review and identification of specimens from Museo de Historia Natural Marina de Colombia (MHNMC) and from National Museum of Natural History, Smithsonian Institution, Washington D. C. (USNM). Standard methodology for monitoring the Eastern Tropical Pacific Seascape was used in December 2006 and March 2007 to sample shallow water echinoderms (1-20 m deep). Malpelo is the richest locality of the Colombian Pacific with 84 species reported (56 % of them deep water organisms), belonging to 22 orders, 42 families and 68 genera, distributed between the surface and a depth of 5000 m. Thirty-six new records for MFFS and Colombian Pacific are reported. In Colombia the shallow water species are widely distributed in the Pacific, while deep forms only occur at Malpelo. The majority of species are mostly related to the Panamanian and Galapagos region showing a possible connectivity. This list increases knowledge on the echinoderm biodiversity from the Malpelo Island in 68 %.
