TL;DR: It is suggested that the tidepool assemblage was stable and resilient in time on short (annual) scales and the constancy in time and space could have been a consequence of eurytopic features of the organisms and the lack of drastic seasonal changes in the tropics.
Abstract: The composition, abundance. species richness and diversity of a rocky intertidal fish assemblage in the central zone of the Pacific coast of Colombia were determined. From July to December 2002. 10 tidepools with volumes ranging from 0.087 to 1.350 m 3 were surveyed. A total of 893 fishes belonging to 14 species and 12 families were found. The most abundant species were Bulhygobius ramosus and Abudefduf concolor, representing 71% of all fishes collected. Bathy gobius ramosus. Malacoctenus zonijer and Gobiesox udustus were residents, Ahudefduf concolor. Abudefduf troschelii, Microsphatodon bairdii, Chaenomugil proboscideus, Halichoeres aesluaricola and Echidna nocturana were transients, and Apogon dovii, Sargocentron suhorbilalis, Cerdule sp, Rypticus nigripinnis and Ctenochaetus marginaliis were considered as accidental visitors. The temporal and spatial variation of assemblage structure was tested. The fish assemblage structure did not differ between months and there was not a clear relationship between tidepool surface area and depth, and community variables. Diversity and species richness were negatively correlated with tidepool height. It is suggested that the tidepool assemblage was stable and resilient in time on short (annual) scales. The constancy in time and space could have been a consequence of eurytopic features of the organisms and the lack of drastic seasonal changes in the tropics.

TL;DR: The molecular phylogenies differ with regard to previous hypotheses of relationships within the Myriprisitinae, resolving a clade of cryptic reef associated and deep water non-reef dwelling lineages (Corniger+Plectrypops+Ostichthys) that is the sister lineage to a monophyletic MyRIpristis.

TL;DR: The squirrelfish genus, Sargocentron, is reported for the first time from Maltese coastal waters within the Central Mediterranean, based on two individuals caught at two different coastal locations in the Maltese Islands within the space of a few days of each other, through the same fishing technique (trammel nets).
Abstract: The squirrelfish genus, Sargocentron, is reported for the first time from Maltese coastal waters within the Central Mediterranean. The record is based on two individuals caught at two different coastal locations in the Maltese Islands within the space of a few days of each other, through the same fishing technique (trammel nets). In view of the impossibility to collect meristic, morphometric and molecular data from the recorded individuals, and due to the close similarity between a number of Sargocentron congeners, the exact taxonomic identity of the captured individuals could not be conclusively confirmed, although the livery on the two caught individuals resulted to be consistent with that of S. rubrum and S. hastatum.

TL;DR: DNA barcoding based on COI gene was demonstrated as a powerful and useful molecular marker in the identification and differentiation of S. spinosissimum and S. tiereoides fish species.
Abstract: Holocentrinae and Myripristinae (Holocentridae) are among the most apparent species in the nocturnal reef fish community. However, there is no clear assent regarding their phylogenetic relations, which is reported in their complicated taxonomic history. In this study, Sargocentron spinosissimum (Temminck et Schlegel, 1843) and Sargocentron tiereoides (Bleeker, 1853) were reported from the Mediterranean coast of Egypt (Damietta coast). This is the first record of these species which is greatly distributed across Indo-Pacific regions and eastern Africa showed the success of these species to migrate to the Mediterranean water with a good adaptation to the new habitats. In the presently reported study, 26 morphometric measurements were recorded and cytochrome c oxidase subunit I (COI) barcodes were recovered for a total of 20 specimens (8 from S. spinosissimum and 12 from S. tiereoides). The specimens from the Damietta coast, Egypt show character states diagnostic of S. spinosissimum: Head is curved. Spinous dorsal fin base straight. Soft dorsal fin base slightly raised. Spinous dorsal fin membranes red. Anterior margin of pelvic and anal fins white. Other fin rays are red. While character states diagnostic of S. tiereoides: Head is straight and pointed. Spinous dorsal fin base almost straight. Soft dorsal fin base not raised and spinous dorsal fin membranes vaguely red. Sequences of both species were submitted to the GenBank and Barcode of Life Database (BOLD) publication database which displayed 99%–100% similarity value S. tiereoides from GenBank and BOLD databases but, S. spinosissimum has not any deposited sequences from GenBank or BOLD. DNA barcoding based on COI gene was demonstrated as a powerful and useful molecular marker in the identification and differentiation of S. spinosissimum and S. tiereoides fish species.
