The benthic hydroid fauna of the Chafarinas Islands (Western Mediterranean), collected during a sur- vey in the summer of 1991, has been studied. A total of 86 species, 20 athecate hydroids and 66 thecate hydroids, has been recorded. For every species, the synonymy, a survey of the material studied and data concerning ecology and distribution are included. The majority of the species has been figured and the most important have been (re)described.

Therefore, the animal is having prime importance in basic biological, aging, and biomedical researches. However, till date, the genome of this organism has not been sequenced and even there is no molecular phylogenetic study to reveal its close relatives. Here, using phylogenetic analysis based on available 16s rRNA gene and protein sequences of Cytochrome oxidase subunit-I (COI or COX1) of T. nutricula, we have predicted the closest relatives of the organism. While we found Nemopsis bachei could be closest organism based on COX1 gene sequence; T. dohrnii may be designated as the closest taxon to T.

    Biological Journal o f the Linne&n Society (1993), 48: 239—266. With 3 figures Zoogeography and life cycle patterns of Mediterranean hydromedusae (Cnidaria) F. BOERO Dipartimento di Biología, Stazione de Biología Marina, Université di Lecce, 73100 Lecce, Italy AND J. BOUILLON Laboratoire de Apologie, Université Libre de Bruxelles, Ave F.D. Roosevelt 50, 1050 Bruxelles, Belgique Recáved July 1990, accepted fo r publication December 1991 The distribution of the 346 hydromedusan species hitherto recorded from the Mediterranean is considered, dividing the species into zoogeographical groups. The consequences for dispersal due to possession or lack of a medusa stage in the life cycle are discussed, and related to actual known distributions. There is contradictory evidence for an influence of life cycle patterns on species distribution. The Mediterranean hydromedusan fauna is composed of 19.5% endemic species. Their origin is debatable. The majority of the remaining Mediterranean species is present in the Atlantic, with various world distributions, and eould have entered the Mediterranean from Gibraltar after the Messinian crisis. Only 8.0% of the fauna is classified as Indo-Pacific, the species being mainly restricted to the eastern basin, some of which have presumably migrated from the Red Sea via the Suez Canai, being then classifiable as Lessepsian migrants. The importance of historical and elimatic factors in determining the composition of the Mediterranean fauna of hydromedusae is discussed. ADDITIONAL KEY WORDS: -Hydrozoa - hydroid -

Rua do Matão, Travessa 14, 101, Cidade Universitária, 05508-900 São Paulo, SP, Brazil. E-mail: [email protected] 2 Instituto de Biologia, Universidade Federal de Uberlândia. Rua Ceará, Campus Umuarama, 38402-400 Uberlândia, MG, Brazil. E-mail: [email protected] ABSTRACT. Hydroids are broadly reported in epiphytic associations from different localities showing marked seasonal cycles. Studies have shown that the factors behind these seasonal differences in hydroid richness and abundance may vary significantly according to the area of study. Seasonal differences in epiphytic hydroid cover and richness were evaluated in a Sargassum cymosum C. Agardh bed from Lázaro beach, at Ubatuba, Brazil. Significant seasonal differences were found in total hydroid cover, but not in species richness. Hydroid cover increased from March (early fall) to February (summer). Most of this pattern was caused by two of the most abundant species: Aglaophenia latecarinata Allman, 1877 and Orthopyxis sargassicola (Nutting, 1915). Hydroid richness seems to be related to S. cymosum size but not directly to its biomass. The seasonal differences in hydroid richness and algal cover are shown to be similar to other works in the study region and in the Mediterranean. Seasonal recruitment of hydroid species larvae may be responsible for their seasonal differences in algal cover, although other factors such as grazing activity of gammarid amphipods on S.
