Using species-level phylogenies, the speciation mode of Gyrodactylus species infecting a single host genus was evaluated. Eighteen Gyrodactylus species were collected from gobies of the genus Pomatoschistus and sympatric fish species across the distribution range of the hosts. The V4 region of the ssrRNA and the internal transcribed spacers encompassing the 5.8S rRNA gene were sequenced; by inc...

An autonomous lander equipped with a video camera (dropcam) was used for in situ observations of the bento-demersal macrofauna on upper continental slope off Punta Pichalo northern Chile, an area permanent coastal upwelling processes, located ~70 km north Iquique. The deployed at nine stations and between 227 798 m depth. According to morphological characteristics, 34 operational taxonomic unit...
