Phylogenetic Analysis of Anostracans (Branchiopoda: Anostraca) Inferred from Nuclear 18S Ribosomal DNA (18S Rdna) Sequences
MOLECULAR PHYLOGENETICS AND EVOLUTION Molecular Phylogenetics and Evolution 25 (2002) 535–544 www.academicpress.com Phylogenetic analysis of anostracans (Branchiopoda: Anostraca) inferred from nuclear 18S ribosomal DNA (18S rDNA) sequences Peter H.H. Weekers,a,* Gopal Murugan,a,1 Jacques R. Vanfleteren,a Denton Belk,b and Henri J. Dumonta a Department of Biology, Ghent University, Ledeganckstraat 35, B-9000 Ghent, Belgium b Biology Department, Our Lady of the Lake University of San Antonio, San Antonio, TX 78207, USA Received 20 February 2001; received in revised form 18 June 2002 Abstract The nuclear small subunit ribosomal DNA (18S rDNA) of 27 anostracans (Branchiopoda: Anostraca) belonging to 14 genera and eight out of nine traditionally recognized families has been sequenced and used for phylogenetic analysis. The 18S rDNA phylogeny shows that the anostracans are monophyletic. The taxa under examination form two clades of subordinal level and eight clades of family level. Two families the Polyartemiidae and Linderiellidae are suppressed and merged with the Chirocephalidae, of which together they form a subfamily. In contrast, the Parartemiinae are removed from the Branchipodidae, raised to family level (Parartemiidae) and cluster as a sister group to the Artemiidae in a clade defined here as the Artemiina (new suborder). A number of morphological traits support this new suborder. The Branchipodidae are separated into two families, the Branchipodidae and Ta- nymastigidae (new family). The relationship between Dendrocephalus and Thamnocephalus requires further study and needs the addition of Branchinella sequences to decide whether the Thamnocephalidae are monophyletic. Surprisingly, Polyartemiella hazeni and Polyartemia forcipata (‘‘Family’’ Polyartemiidae), with 17 and 19 thoracic segments and pairs of trunk limb as opposed to all other anostracans with only 11 pairs, do not cluster but are separated by Linderiella santarosae (‘‘Family’’ Linderiellidae), which has 11 pairs of trunk limbs. -
Betta Splendens: a Territorial Note
Bulletin of the Psychonomic Society 1980,16 (6),484-485 Betta splendens: A territorial note PAUL M. BRONSTEIN Trenton State College, Trenton, New Jersey 08625 Two communities of Siamese fighting fish were observed, each for about 4 months. Males occasionally built nests, and these structures were always located in corners. Consistent with Goldstein's (1975) report, male Bettas chose isolated areas for nest building and spawning. This paper is a brief report appended to a set of twice daily (1000 and 1600 h). During feedings, the existence studies concerned with the style and function of aggres and location of nests, along with subjects' positions with regard sion in male Siamese fighting fish (Betta sp/endens) to any nests, were recorded. (Bronstein, in press). In that longer article, I showed, first, that bettas build nests against vertical surfaces, Results On May 7, 1980, the male was found with a bubble with crevices and corners more preferred than flat nest in an external corner of the tank. The male, now walls. Second, it was demonstrated that nests were observed for 10 min/feeding, located himself beneath constructed far from male competitors. Third, exposure the nest almost exclusively, and this nest flxation to a male challenger led nest builders to fixate on and persisted through May 9. He left the nest only briefly enlarge their nests. and then only when in immediate pursuit of females. These individual behaviors suggest a strategy whereby During these 72 h, the male spawned with two of the animals disperse and segregate themselves as a preface to females, one at a time, near his nest. -

Milne Edwards, 1840) (now Phallocryptus spinosa), Streptocephalus simplex, 1906, S. dichotomus Baird, 1860, S. maliricus Qadri and Baqai, 1956, S. lahorensis Ghauri and Mahoon, 1980, Branchipus schaefferi Fischer, 1834, Chirocephalus priscus Daday, 1910 and Artemia sp. In the present report these Pakistani species are reviewed. Streptocephalus dichotomus collected from Pasni (Mekran), housed in the Smithsonian National Museum of Natural History, USA (cat no. 213712) is inserted herein and another specimen of Streptocephalus sp., from a new locality, collected from Kalat not yet reported, is illustrated and described in this report, thus extending genus range further Northward. The need for further surveys directed towards getting the knowledge necessary in order to correctly understand and manage temporary pools- the elective habitat of large branchiopods is stressed.

Vernal Pool Fairy Shrimp (Branchinecta Lynchi)
Invertebrates Vernal Pool Fairy Shrimp (Branchinecta lynchi) Vernal Pool Fairy Shrimp (Brachinecta lynchi) Status State: Meets the requirements as a “rare, threatened, or endangered species” under CEQA Federal: Threatened Critical Habitat: Designated 2006 (USFWS 2006) Population Trend Global: Declining due to habitat loss and fragmentation (Eriksen and Belk 1999) State: As above Within Inventory Area: Unknown Data Characterization The location database for the vernal pool fairy shrimp (Brachinecta lynchi) within the inventory area includes 6 records from 1993, 1997, and 1999. The majority of locations are vernal pools within non-native grassland. Other natural and artificial habitats have a high probability of being occupied by additional populations of the vernal pool fairy shrimp throughout the grassland habitats within the ECCC HCP/NCCP inventory area. Beyond the original description (Eng et al. 1990), a scanning electron micrograph of the cyst (resting egg) (Hill and Shepard 1997), and some generalized natural history data (Helm 1997), no peer-reviewed technical literature has been published concerning the vernal pool fairy shrimp. Eriksen and Belk (1999) presented a brief discussion of the vernal pool fairy shrimp and provided a distribution map. Range The vernal pool fairy shrimp is found from Jackson County near Medford, Oregon, throughout the Central Valley, and west to the central Coast Ranges. Isolated southern populations occur on the Santa Rosa Plateau and near Rancho California in Riverside County (Eng et al.1990, Eriksen -

Phyllopods of the genera Triops, Lepidums, and Branchinecta are common inhabitants of many ephemeral lakes in the American West. Tadpole shrimp (Triops spp. and Lepidums spp.) are known to have been a food source in Mexico, and fairy shrimp fBranchinecta spp.) were eaten by the aborigi nal occupants of the Great Basin. Where found, these crustaceans generally occur in numbers large enough to supply abundant calories and nutrients to humans. Several ephemeral lakes studied in the Mojave Desert arul northern Great Basin currently sustain large seasonal populations of these crusta ceans and also are surrounded by numerous small prehistoric camp sites that typically contain small artifactual assemblages consisting largely of milling implements. -

A Commented Check-List of the Balearic Branchiopoda (Crustacea)
A COMMENTED CHECK-LIST OF THE BALEARIC BRANCHIOPODA (CRUSTACEA) J. LI. Pretus Departament d'Ecologia, Facultat de Biologia, Universitat de Barcelona. Diagonal 645, 08028 Barcelona. Spain. Keywords: Branchiopoda, Baleanc Isles, Spain. ABSTRACT 43 species of branchiopoda have so far been recorded from the Balearic islands, including species mentioned here for the first time. Chorologic grouping hows an important stock of species associated with semiarid regions of continental inland basins, both from fresh and atalassohaline waters. Their biogeographic significance and age is discussed in relation to the neotectonics of the islands and the possible existence of barren conditions in part of the insular landscape in the past.
