    PHYLOGENY AND HISTORICAL BIOGEOGRAPHY OF LIMPETS OF THE ORDER PATELLOGASTROPODA BASED ON MITOCHONDRIAL DNA SEQUENCES TOMOYUKI NAKANO AND TOMOWO OZAWA Department of Earth and Planetary Sciences, Nagoya University, Nagoya 464-8602,Japan (Received 29 March 2003; accepted 6June 2003) ABSTRACT Using new and previously published sequences of two mitochondrial genes (fragments of 12S and 16S ribosomal RNA; total 700 sites), we constructed a molecular phylogeny for 86 extant species, covering a major part of the order Patellogastropoda. There were 35 lottiid, one acmaeid, five nacellid and two patellid species from the western and northern Pacific; and 34 patellid, six nacellid and three lottiid species from the Atlantic, southern Africa, Antarctica and Australia. Emarginula foveolata fujitai (Fissurellidae) was used as the outgroup. In the resulting phylogenetic trees, the species fall into two major clades with high bootstrap support, designated here as (A) a clade of southern Tethyan origin consisting of superfamily Patelloidea and (B) a clade of tropical Tethyan origin consisting of the Acmaeoidea. Clades A and B were further divided into three and six subclades, respectively, which correspond with geographical distributions of species in the following genus or genera: (AÍ) north­ eastern Atlantic (Patella ); (A2) southern Africa and Australasia ( Scutellastra , Cymbula-and Helcion)', (A3) Antarctic, western Pacific, Australasia ( Nacella and Cellana); (BÍ) western to northwestern Pacific (.Patelloida); (B2) northern Pacific and northeastern Atlantic ( Lottia); (B3) northern Pacific (Lottia and Yayoiacmea); (B4) northwestern Pacific ( Nipponacmea); (B5) northern Pacific (Acmaea-’ânà Niveotectura) and (B6) northeastern Atlantic ( Tectura). Approximate divergence times were estimated using geo­ logical events and the fossil record to determine a reference date.

Most studies of territoriality have focused on vertebrates, which have large territories and even larger home ranges. While there are many models used to examine territories and territorial interactions, testing the models is limited by the logistics of working with the typical model organisms, vertebrates, and their large territories. An ideal organism for the experimental examination of territoriality would exhibit clear territorial behavior in the field and laboratory, would be easy to maintain in the laboratory, defend a small territory, and have movements and social interactions that were easily followed.
