Rotifera: Monogononta) from Minorcan Inland Waters (Balearic Isles: Spain
CONTRIBUTION TO THE KNOWLEDGE OF THE ROTIFER FAUNA (ROTIFERA: MONOGONONTA) FROM MINORCAN INLAND WATERS (BALEARIC ISLES: SPAIN) J. De Manuel Departament d'Ecologia, Facultat de Biologia, Universitat de Barcelona. Avda. Diagonal 645, 08028 Barcelona. Spain. Keywords: Rotifera, new records, Baleanc, archipelago, biogeography, Spain. ABSTRACT Forty-four species of rotifers have been identified in Minorca inland waters. Permanent ponds, temporary pools, flowing waters, and artificial pools were sampled. Most of the species are new records for the island and twenty- nine are new to the Balearic Isles. The families Brachionidae and Lecanidae provide half of the taxa. Keratella procurva (Thorpe, 1912), which is considered a subtropical species, occurred with a widespread distnbution in the island. Different taxa and «Formenkreis» found are mentioned. Original drawings and scanning photomicrographs of some species are presented. Typical assemblages of populations from every environment are also described. INTRODUCTION ficult if we are focusing on the rotifer commu- nities.

The Rotifers of Spanish Reservoirs: Ecological, Systematical and Zoogeographical Remarks
91 THE ROTIFERS OF SPANISH RESERVOIRS: ECOLOGICAL, SYSTEMATICAL AND ZOOGEOGRAPHICAL REMARKS Jordi de Manuel Barrabin Departament d'Ecologia, Universitat de Barcelona. Avd. Diagonal 645,08028 Barcelona. Spain,[email protected] ABSTRACT This article covers the rotifer data from a 1987/1988 survey of one hundred Spanish reservoirs. From each species brief infor- mation is given, focused mainly on ecology, morphology, zoogeography and distribution both in Spain and within reservoirs. New autoecological information on each species is also established giving conductivity ranges, alkalinity, pH and temperature for each. Original drawings and photographs obtained on both optical and electronic microscopy are shown of the majority of the species found. In total one hundred and ten taxa were identified, belonging to 101 species, representing 20 families: Epiphanidae (1): Brachionidae (23); Euchlanidae (1); Mytilinidae (1 ): Trichotriidae (3): Colurellidae (8); Lecanidae (1 5); Proalidae (2); Lindiidae (1); Notommatidae (5); Trichocercidae (7); Gastropodidae (5); Synchaetidae (1 1); Asplanchnidae (3); Testudinellidae (3); Conochiliidae (5):Hexarthridae (2); Filiniidae (3); Collothecidae (2); Philodinidae (Bdelloidea) (I). Thirteen species were new records for the Iberian rotifer fauna: Kerutella ticinensis (Ehrenberg); Lepadella (X.) ustucico- la Hauer; Lecane (M.) copeis Harring & Myers; Lecane tenuiseta Harring: Lecane (M.) tethis Harring & Myers; Proales fal- laciosa Wulfert; Lindia annecta Harring & Myers; Notommatu cerberus Hudson & Gosse; Notommata copeus Ehrenberg: Resticula nyssu Harring & Myers; Trichocerca vernalis Hauer; Gustropus hyptopus Ehrenberg: Collothecu mutabilis Hudson.

Nandini 1 1 Laboratory of Aquatic Zoology, FES Iztacala, National Autonomous University of Mexico, Av. de Los Barrios No. 1, Tlalnepantla 54090, Mexico; [email protected] 2 Posgrado en Ciencias del Mar y Limnología, Universidad Nacional Autónoma de México, Ciudad Universitaria, Mexico City 04510, Mexico; [email protected] * Correspondence: [email protected]; Tel.: +52-55-56231256 Abstract: A review of the Mexican rotifer species diversity is presented here. To date, 402 species of rotifers have been recorded from Mexico, besides a few infraspecific taxa such as subspecies and varieties. The rotifers from Mexico represent 27 families and 75 genera. Molecular analysis showed about 20 cryptic taxa from species complexes. The genera Lecane, Trichocerca, Brachionus, Lepadella, Cephalodella, Keratella, Ptygura, and Notommata accounted for more than 50% of all species recorded from the Mexican territory. The diversity of rotifers from the different states of Mexico was highly heterogeneous. Only five federal entities (the State of Mexico, Michoacán, Veracruz, Mexico City, Aguascalientes, and Quintana Roo) had more than 100 species. Extrapolation of rotifer species recorded from Mexico indicated the possible occurrence of more than 600 species in Mexican water bodies, hence more sampling effort is needed. In the current review, we also comment on the importance of seasonal sampling in enhancing the species richness and detecting exotic rotifer taxa in Mexico.

A total of 44 taxa belonging to 21 genera and 14 families were identified, in addition to a group of unidentifiable bdelloids. Of the fully identified species, 17 are the first thalassic records for the U.S., including Encentrum melonei sp. nov. and Synchaeta grossa sp. nov., which are new to science, and Colurella unicauda Eriksen, 1968, which is new to the Nearctic region. Moreover, a refined description of Encentrum rousseleti (Lie-Pettersen, 1905) is presented. During the survey, we characterized samples by different salinity values and ecosystems and compared species composition across communities to test for possible ecological correlations. Results indicate that both salinities and ecosystems are a significant predictor of rotifer diversity, supporting that biodiversity estimates of small species provide fundamental information for biomonitoring. Finally, we provide a comprehensive review of the diversity and distribution of thalassic rotifers in the United States. -
A Modern Approach to Rotiferan Phylogeny: Combining Morphological and Molecular Data
Molecular Phylogenetics and Evolution 40 (2006) 585–608 www.elsevier.com/locate/ympev A modern approach to rotiferan phylogeny: Combining morphological and molecular data Martin V. Sørensen ¤, Gonzalo Giribet Department of Organismic and Evolutionary Biology, Museum of Comparative Zoology, Harvard University, 16 Divinity Avenue, Cambridge, MA 02138, USA Received 30 November 2005; revised 6 March 2006; accepted 3 April 2006 Available online 6 April 2006 Abstract The phylogeny of selected members of the phylum Rotifera is examined based on analyses under parsimony direct optimization and Bayesian inference of phylogeny. Species of the higher metazoan lineages Acanthocephala, Micrognathozoa, Cycliophora, and potential outgroups are included to test rotiferan monophyly. The data include 74 morphological characters combined with DNA sequence data from four molecular loci, including the nuclear 18S rRNA, 28S rRNA, histone H3, and the mitochondrial cytochrome c oxidase subunit I. The combined molecular and total evidence analyses support the inclusion of Acanthocephala as a rotiferan ingroup, but do not sup- port the inclusion of Micrognathozoa and Cycliophora. Within Rotifera, the monophyletic Monogononta is sister group to a clade con- sisting of Acanthocephala, Seisonidea, and Bdelloidea—for which we propose the name Hemirotifera. We also formally propose the inclusion of Acanthocephala within Rotifera, but maintaining the name Rotifera for the new expanded phylum. Within Monogononta, Gnesiotrocha and Ploima are also supported by the data. The relationships within Ploima remain unstable to parameter variation or to the method of phylogeny reconstruction and poorly supported, and the analyses showed that monophyly was questionable for the fami- lies Dicranophoridae, Notommatidae, and Brachionidae, and for the genus Proales. -

In addition to this review we describe a new species encountered during examination of freshwater habitats of Inner Mongolia, P.R.China. This new species, Mytilina wangi n. sp., appears to belong to the Mytilina mucronata - ventralis complex but differs from the known taxa in the group by its domed lorica and relatively short toes. We provide an annotated checklist of the Chinese representatives of the genus and discuss the species of the M. mucronata-ventralis group. We suggest treating M. brevispina (Ehrenberg, 1830) and M. ventralis (Ehrenberg, 1830)(synonym: M. macracantha (Gosse, 1886)) as separate species-level taxa rather than as two infrasubspecific variants of the same species, and argue that Mytilina trigona var. bispinosa Wang, 1961 is a misidentified M. -

Approximately 398 species of rotifers are recorded. The rotifer fauna of Thailand has been investigated quite comprehensively and these studies focus on four main parts of the country: the northern, north-eastern, central and southern. The number of rotifers on record is the highest in the north-eastern part (275), followed by the southern part (261), the central part (182) and the northern part (115). The majority of Thai Rotifera belongs to family Lecanidae (24.4%), Lepadellidae (11.3%), Brachionidae (11.1%), Trichocercidae (9.0%) and Floscu- lariidae (9.0%). The most diverse genus is Lecane followed by Trichocerca, Lepadella and Brachionus.only Although most Thai rotifers are cosmopolitan, there are a number of Oriental endemics, including some strict Thai or regional endemics. Illoricate rotifers and bdelloids are understudied, while experimental and molecular approaches promise to add most to our knowledge and understanding of the role of rotifers in ecosystem functioning. use Key words: Rotifer, biodiversity, biogeography, endemicity, Thailand.
