Taxonomic Groups

Habitats defined by various biological and environmental variables are increasingly assumed to be surrogates for biodiversity. This study tested this assumption for temperate subtidal rocky reefs off south-eastern Australia by investigating the consistency of floral and faunal macrobenthic assemblages within habitats defined by dominant vegetation, substratum lithology, depth, wave exposure and region. Taxonomic groups included seagrasses, rhodophytes, chlorophytes, phaeophytes, hydroids, bryozoans, molluscs, polychaetes, pycnogonids and echinoderms. The results from multivariate statistical analyses indicated that, although variation between replicate samples is high, habitats as defined by dominant vegetation and, to a lesser extent, region supported consistent floral and faunal assemblages. The patterns did not emphasize a broad-scale biogeographic gradient, but rather the environmental heterogeneity of the coastline at scales of 10–100 km.

AbstractThe early life history traits of the labrisomid blenny Auchenionchus crinitus (Jenyns, 1842) from subtidal rocky reefs were studied, based on microstructure analysis of sagittae of their pelagic larvae (4.01 mm NL −12.50 mm SL). Ichthyoplankton was collected in shallow (<20 m) nearshore waters off Isla Santa María, Antofagasta, northern Chile every 15 days during austral autumn–winter 2014 (five sampling days). During late May and early June, larval abundance was low (median ± MAD, 39.06 ± 5.08 ind. 100 m−3), increasing significantly during mid-June to early August (110.98 ± 47.66 ind. 100 m−3). Using 354 sagittae, the back-calculated hatch dates indicated the occurrence of three hatching events, two in autumn and one in winter. Hatching occurred mainly during the illuminated phases of the lunar cycle. All three batches had similar estimated larval sizes at hatch (3.2–3.7 mm SL), as well as similar growth rates (0.19–0.22 mm day−1) during the first 30 days of life. During the study period, shallow waters were well mixed, with seawater temperature of 14.73 ± 0.58°C and salinity of 34.84 ± 0.04. This is the first estimation of early life history traits of this cryptobenthic species from rocky reefs of Chile.
