“…The species was only recently recognized from Puerto Rico (Ballantine et al, 2015); however, it is typically found in shallow water (Taylor, 1960 Leichter et al (2008). Taylor (1960) indicated a maximum depth of 72 m for the species.…”

“…Specimens: DLB7314, DLB7381, 50 m; DLB7056, 52 m; DLB7509, 61 m; DLB8071, 70 m. Taylor (1960) indicated that the species was primarily restricted to shallow water; however, he also reported that dredged material had been collected to 37 m. Gilmartin (1960) reported C. parvula from 63 m in Eniwetok, and Joly and Yoneshigue Braga (1966) Botryocladia pyriformis was reported to 60 m in Florida by Leichter et al (2008) and to 70 m by . The deepest depth report for the species is 73 m by Frederick (1963) Ballantine (1985) to a maximum depth of 49 m as well as by Bucher et al (1990) The type locality for the species is a 17-m-deep algal plain in Puerto Rico (Ballantine, 1985).…”

“…Frederick (1963) reported the species to 64 m from Bermuda, and Hanisak and Blair (1988a) recorded the species from 34 to 93 m off the east coast of Florida. Halymenia pseudofloresii was reported to 60 m (as Halyme nia floresii (Clemente) Agardh) by Leichter et al (2008) from Florida and to the same depth from Bermuda by Frederick (1963). Dawes and Van Breedveld (1969) also reported the species (as H. floresii) from Florida at 73 m.…”

“…Dredging collections to 90 m in the Flower Garden Banks National Marine Sanctuary (Gulf of Mexico) by Fredericq's research group (reported in Fredericq, 2003, 2005; further resulted in the characterization of new algal species and new species records. More recently, Leichter et al (2008) reported on distribution and spatial extent of algal communities off the Florida coast based on broad systematic groupings, using ROVs and scuba.…”

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.

“…These communities have moderate percent areal cover (10-50%) of hard and soft corals, benthic algae, and sponges (Leichter et al 2008). Reef crests lie at 3 to 10 m depth, with forereefs sloping to 30 to 35 m depth, becoming gradually discontinuous until they are semi-isolated patches on sand.…”

Shallow water zooxanthellate coral reefs grade into ecologically distinct mesophotic coral ecosystems (MCEs) deeper in the euphotic zone. MCEs are widely considered to start at an absolute depth limit of 30m deep, possibly failing to recognise that these are distinct ecological communities that may shift shallower or deeper depending on local environmental conditions. This study aimed to explore whether MCEs represent distinct biological communities, the upper boundary of which can be defined and whether the depth at which they occur may vary above or below 30m. Mixed-gas diving and closed-circuit rebreathers were used to quantitatively survey benthic communities across shallow to mesophotic reef gradients around the island of Utila, Honduras. Depths of up to 85m were sampled, covering the vertical range of the zooxanthellate corals around Utila. We investigate vertical reef zonation using a variety of ecological metrics to identify community shifts with depth, and the appro-priateness of different metrics to define the upper MCE boundary. Patterns observed in scleractinian community composition varied between ordination analyses and approaches utilising biodiversity indices. Indices and richness approaches revealed vertical community transition was a gradation. Ordination approaches suggest the possibility of recognising two scleractinian assemblages. We could detect a mesophotic and shallow community while illustrating that belief in a static depth limit is biologically unjustified. The switch between these two communities occurred across bathymetric gradients as small as 10m and as large as 50m in depth. The difference between communities appears to be a loss of shallow specialists and increase in depth-generalist taxa. Therefore, it may be possible to define MCEs by a loss of shallow specialist species. To support a biological definition of mesophotic reefs, we advocate this analytical framework should be applied around the Caribbean and extended into other ocean basins where MCEs are present.
