Autonomous reef monitoring structures (ARMS) have been proposed as a standardized, passive, nondestructive sampling tool. This study assessed the ability of ARMS to capture the cryptic species diversity of two coral reefs by recording species richness and taxonomic representativeness using conventional taxonomy. The capacity of ARMS, as artificial substrates, to favor the establishment of nonindigenous species over native species was also evaluated. The use of ARMS allowed the detection of 370 species morphotypes from nine phyla, yielding 13 new records of geographic distribution expansion, one exotic species for the Gulf of México and the Caribbean Sea, and six newly described species. It was also possible to make spatial comparisons of species richness between both reefs. ARMS captured cryptic diversity exceptionally well, with the exception of echinoderms. Furthermore, these artificial structures did not hinder the colonization ability of native species; in fact, the colonization patterns on the structures themselves represented the spatial differences in the structure of benthic assemblages. This study represents the first effort to make a conventional taxonomic description of the cryptic fauna of the Yucatan Peninsula using ARMS. It is recommended to assess coral reef species diversity, but more taxonomists specialized in marine invertebrates are needed.

Acantholaimus (Nematoda: Chromadoridae) is considered to be one of the most abundant and species-rich genera of deep-sea free-living nematodes and has a world-wide distribution. To date, 50 Acantholaimus species are known globally, although in all the oceans many more undescribed species have been recorded. Local species diversity of the genus is often very high and may amount to several dozen species in one deep-sea locality. The present review summarises data on morphology (with illustrations), taxonomy, ecology, and biology of this genus. An emended genus diagnosis, a list of species with their known locations, and a tabular key to species are provided. Acantholaimus ewensis Platt & Zhang, 1982 n. syn. is proposed as a junior synonym of A. polydentatus Gerlach, 1951.

This study reveals the effect of elevatedpCO2onPorites cylindricaandGalaxea fascicularis. The corals responded differently under elevatedpCO2. Zooxanthellae cell density, cell mitotic index, and photosynthesis rate ofP. cylindricadecreased drastically under the elevatedpCO2. At the end of the experiment,P. cylindricasuffered from a declining calcium carbonate precipitation rate.G. fascicularisincreased its respiration rate and expelled 71% of its symbiotic zooxanthellae algae under elevatedpCO2. Photosynthetic pigments in the remaining zooxanthellae algae increased from 1.85 to 11.5 times to sustain its photosynthetic outputs. At the end of the experiment,G. fascicularismanaged to increase the rate of its calcium carbonate precipitation. IncreasepCO2in the atmosphere may affect species diversity of coral reefs.
