“…This growth phase is typically seen in shallow-water environments in the Caribbean and is encountered only occasionally in deep water. The species was reported to 49 m in Bermuda by Frederick (1963), from 50 to 60 m in Brazil (Magalhães et al, 2015), and to 63 m in the Pacific by Gilmartin (1960).…”

“…For oceanic water off Brazil, there is a sharp decline in photosynthetically active radiation at 30 m, where less than 2% of surface irradiance reaches (Magalhães et al, 2015). In situ sea conditions are thought to be more stable in deeper water than in shallow water, with decreased disturbance and a lower fluctuation in water temperature; however, the presence of internal waves may periodically alter localized temperature regimes (Appeldoorn et al, 2016).…”

Aponte SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTIONEmphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: s m i t h s o n i a n c o n t r i b u t i o n s t o b o t a n y • n u m b e r 1 0 5The Cover images, from left to right: Edge of insular shelf, offshore from La Parguera; technical divers' descent to the mesophotic; bottom habit, edge of insular shelf, "Weinberg," offshore from La Parguera.

“…Physical characteristics of MCEs, in comparison to their shallower counterparts, include reduced photosynthetically active radiation, decreases in seawater temperature and greater protection from strong wave action and thermal stress (Lesser et al 2009;Pyle et al 2016 community composition and habitat complexity (Magalhães et al 2015;Heyns et al 2016), and in turn, they all affect the structure of reef fish assemblages (McGehee 1994;Friedlander and Parrish 1998). Water temperature has been suggested as a particularly important environmental factor that could restrict distributions of fish and other ectothermic organisms through effects on physiological processes (Pörtner 2002;Behrens and Lafferty 2007;Kahng et al 2012).…”

Changes in mesophotic reef fish assemblages along depth and geographical gradients in the Northwestern Hawaiian Islands

2017

Mesophotic coral ecosystems (MCEs) extend from 30 to 150 m in depth and support diverse communities of marine organisms. We investigated changes in the structure of mesophotic reef fish assemblages (27-100 m) in the Northwestern Hawaiian Islands (NWHI) along depth and geographical gradients using open-and closed-circuit trimix diving. There were clear changes in the assemblage structure from the southeastern to the northwestern end of the NWHI and from shallow to deep waters. Interactive effects of depth and location were also detected. MCEs in the NWHI can be treated as three regions: southeastern and mid regions primarily separated by the presence and absence, respectively, of the introduced species Lutjanus kasmira, and a northwestern region where fish assemblages are largely composed of endemic species. These spatial patterns may be explained, at least in part, by differences in temperature among the regions.

“…In Brazil, coralline and sandstone reefs occur in the Northern, Northeastern and Central coast from the Amazon River mouth south to the Doce River mouth, off Espírito Santo State (~19 o 50'S) (Moura et al 2013, 2016, Pinheiro et al 2015a, while rocky reefs predominate in the subtropical portion of the coast, southwards to Rio Grande do Sul State (~32 o 30'S), as well as in the three oceanic archipelagos , Krajewski & Floeter 2011, Magalhães et al 2015. The physical complexity of coralline and rocky reefs is associated to a remarkably high diversity of fish and several other groups, which overcomes that of any other aquatic habitat (Reaka-Kudla 1997, Spalding et al 2001).…”

This paper presents a checklist of the reef fish fauna of the Anchieta Island State Park, a no-take zone in which no extractive activities are allowed, in Ubatuba, Southeastern Brazil. Data was obtained between 2011 and 2013, mainly through underwater observations with snorkelling and SCUBA, and secondarily using scientific fishing (trawling). Published and unpublished data were also verified and compiled. A total of 103 reef fish species, distributed in 78 genus and 50 families was recorded. Haemulidae was the richest family (n=7 species), followed by Epinephelidae (n=6), Pomacentridae, Carangidae and Tetraodontidae (n= 4 each). Haemulon was also the most speciose genera (n=5), followed by Stegastes, Acanthurus and Mycteroperca (n=3 each). Sixty-nine species (67%) are included in global and regional Red Lists. Twenty-five species (24.2%) are within the categories Critically Endangered (CR), Endangered (EN), Vulnerable (VU) and Near-Threathened (NT). The network of Marine Protected Areas in Southeastern Brazil is still incipient, and the considerable number of threatened species in the Anchieta Island State Park clearly indicates the importance of the study area for the conservation of coastal and reef fishes.Key words: rocky reefs; species richness; scientific diving; ichthyology; conservation. Peixes recifais do Parque Estadual da Ilha Anchieta, Sudoeste do Atlântico, BrasilResumo: Este artigo apresenta uma lista de espécies de peixes recifais do Parque Estadual da Ilha Anchieta, uma área na qual nenhuma atividade extrativista é permitida, em Ubatuba, Sudeste do Brasil. Os dados foram coletados entre 2011 e 2013, principalmente por observações subaquáticas com o uso de mergulhos livres e autônomos e, secundariamente, através de pescaria científica (arrasto). Dados publicados e não publicados também foram verificados e compilados. Foram registradas 103 espécies de peixes recifais distribuídas em 78 gêneros e 50 famílias. Haemulidae foi a família com maior número de espécies (n=7 espécies), seguida por Epinephelidae (n=6), Pomacentridae, Carangidae e Tetraodontidae (n=4 cada). Os gêneros com maior número de espécies foram Haemulon (n=5) e Stegastes¸ Acanthurus e Mycteroperca (n=3 cada). Sessenta e nove espécies (67%) estão inclusas em listas vermelhas de espécies ameaçadas globais e regionais. Vinte e cinco espécies (24,2%) são classificadas nas categorias Criticamente em Perigo (CR), Em Perigo (EN), Vulnerável (VU) e Quase Ameaçadas (NT). A rede de Áreas Marinhas Protegidas no Sudeste do Brasil ainda é incipiente e o considerável número de espécies ameaçadas no Parque Estadual da Ilha Anchieta indica claramente a importância da área de estudo para a conservação de peixes recifais e costeiros.
