Deep reefs are not refugium for shallow-water fish communities in the southwestern Atlantic
<p>1. The deep reef refugia hypothesis (DRRH) predicts that deep reef ecosystems may act as refugium for the biota of disturbed shallow waters. Because deep reefs are amongst the most understudied habitats on Earth, formal tests of the DRRH remain scarce. If the DRRH is valid at the community level, the diversity of species, functions and lineages of fish communities of shallow reefs should be encapsulated in deep reefs.</p> <p>2. We tested the DRRH by assessing the taxonomic, functional and phylogenetic diversity of 22 Brazilian fish communities between 2 and 62m depth. We partitioned the gamma diversity of shallow (<30m) and deep reefs (>30m) into independent alpha and beta components, accounted for species' abundance, and assessed if beta patterns were mostly driven by spatial turnover or nestedness.</p> <p>3. We recorded 3821 fishes belonging to 85 species and 36 families. Contrary to DRRH expectations, only 48% of the species occurred in both shallow and deep reefs. Alpha diversity of rare species was higher in deep reefs as expected, but alpha diversity of typical and dominant species did not vary with depth. Alpha functional diversity was higher in deep reefs only for rare and typical species, but not for dominant species. Alpha phylogenetic diversity was consistently higher in deep reefs, supporting DRRH expectations.</p> <p>4. Profiles of taxonomic, functional, and phylogenetic beta diversity indicated that deep reefs were not more heterogeneous than shallow reefs, contradicting expectations of biotic homogenization near sea surface. Furthermore, pairwise beta diversity analyses revealed that the patterns were mostly driven by spatial turnover rather than nestedness at any depth.</p> <p>5<i>. </i>Conclusions: Although some results support the DRRH, most indicate that the shallow-water reef fish diversity are not fully encapsulated in deep reefs. Every reef contributes significantly to the regional diversity and must be managed and protected accordingly.</p>

FIG. 1 in A New Non-Invasive Technique for Temporarily Tagging Coral Reef Fishes
FIG. 1. (A) Graphic scheme of the tagging procedure: i) Dry the scales of the fish, scraping gently with a clean cotton tip (moving the top of the cotton tip in the same direction as the fish scales); ii) Apply on the dried area a very small drop of topical tissue adhesive; iii) Place the tag on the spot of adhesive using tweezers; iv) Using a wet cotton tip, press on the tag for few seconds (ensuring that there are no bubbles of air between the tag and the fish scales); v) Finally, apply a small amount of adhesive on the right and left extremities of the tag. This procedure requires less than a minute for each tag. (B) Graphic scheme and photo examples of the six possible combinations of the tags. Positions of the tags along the fish body (horizontal— posterior in orange, middle in yellow, and anterior in purple; and vertical—dorsal in red, central in blue, and ventral in green).
