CHAPTERS These include species-rich taxa such as Nematoda and Platyhelminthes, and as taxa with few or even only one species, such as Micrognathozoa (Limnognathia maerski) and Cycliophora (Symbion pandora). All Acanthocephala and subgroups of Platyhelminthes and Nematoda, are parasites that often exhibit complex life cycles. Most of the taxa described are marine, but some have also invaded freshwater or the terrestrial environment. “Aschelminthes” are not a natural group, instead, two taxa have been recognized that were earlier summarized under this name. Gnathifera include taxa with a conspicuous jaw apparatus such as Gnathostomulida, Micrognathozoa, and Rotifera. Although they do not possess a jaw apparatus, Acanthocephala also belong to Gnathifera due to their epidermal structure. ©Encyclopedia of Life Support Systems (EOLSS) BIOLOGICAL SCIENCE FUNDAMENTALS AND SYSTEMATICS – Vol.

  • I FLATWORM PREDATION on JUVENILE FRESHWATER
    FLATWORM PREDATION ON JUVENILE FRESHWATER MUSSELS A Thesis Presented to the Graduate College of Southwest Missouri State University In Partial Fulfillment of the Requirements for the Master of Science Degree By Angela Marie Delp July 2002 i FLATWORM PREDATION OF JUVENILE FRESHWATER MUSSELS Biology Department Southwest Missouri State University, July 27, 2002 Master of Science in Biology Angela Marie Delp ABSTRACT Free-living flatworms (Phylum Platyhelminthes, Class Turbellaria) are important predators on small aquatic invertebrates. Macrostomum tuba, a predominantly benthic species, feeds on juvenile freshwater mussels in fish hatcheries and mussel culture facilities. Laboratory experiments were performed to assess the predation rate of M. tuba on newly transformed juveniles of plain pocketbook mussel, Lampsilis cardium. Predation rate at 20 oC in dishes without substrate was 0.26 mussels·worm-1·h-1. Predation rate increased to 0.43 mussels·worm-1·h-1 when a substrate, polyurethane foam, was present. Substrate may have altered behavior of the predator and brought the flatworms in contact with the mussels more often. An alternative prey, the cladoceran Ceriodaphnia reticulata, was eaten at a higher rate than mussels when only one prey type was present, but at a similar rate when both were present. Finally, the effect of flatworm size (0.7- 2.2 mm long) on predation rate on mussels (0.2 mm) was tested. Predation rate increased with predator size. The slope of this relationship decreased with increasing predator size. Predation rate was near zero in 0.7 mm worms. Juvenile mussels grow rapidly and can escape flatworm predation by exceeding the size of these tiny predators.

This knowledge has challenged the ‘Everything is Everywhere’ hypothesis and also Meiofauna partly explains the meiofauna paradox of widespread nominal species with limited dispersal abilities. Here, we Species delimitation investigated species diversity within the marine microturbellarian Astrotorhynchus bifidus sensu lato in the turbellaria Northeast Pacific Ocean.

This included the development of rhabdocoel-specific COI barcode primers, which also have the potential to aid in species identification and delimitation in other rhabdocoels. Secondary Species Hypotheses (SSHs) corresponding to morphospecies and pseudo-cryptic species were then proposed based on the minimum consensus of different PSHs. Our results showed that (a) there are at least five species in the A. bifidus complex in the Northeast Pacific Ocean, four of which can be diagnosed based on stylet morphology, (b) the A.

Vladychenskaya Belozersky Institute of Physicochemical Biology, Moscow State University, Moscow, 119992 Russia e-mail: [email protected] Received December 29, 2004 Abstract—Phylogenetic relationships within the group of molting protostomes were reconstructed by compar- ing the sets of 18S and 28S rRNA gene sequences considered either separately or in combination. The reliability of reconstructions was estimated from the bootstrap indices for major phylogenetic tree nodes and from the degree of congruence of phylogenetic trees obtained by different methods. By either criterion, the phylogenetic trees reconstructed on the basis of both 18 and 28S rRNA gene sequences were better than those based on the 18S or 28S sequences alone. The results of reconstruction are consistent with the phylogenetic hypothesis clas- sifying protostomes into two major clades: molting Ecdysozoa (Priapulida + Kinorhyncha, Nematoda + Nema- tomorpha, Onychophora + Tardigrada, Myriapoda + Chelicerata, and Crustacea + Hexapoda) and nonmolting Lophotrochozoa (Plathelminthes, Nemertini, Annelida, Mollusca, Echiura, and Sipuncula). Nematomorphs (Nematomorpha) do not belong to the clade Cephalorhyncha (Priapulida + Kinorhyncha). It is concluded that combined data on the 18S and 28S rRNA gene sequences provide a more reliable basis for phylogenetic infer- ences. Key words: 18S rRNA, 28S rRNA, molecular phylogeny, Protostomia, Ecdysozoa, Arthropoda, Cephalorhyn- cha, Nematoda, Nematomorpha INTRODUCTION accepted in zoology and became basic in textbooks Since its origin at the turn of the 20th century, [12, 13].

  • The Shoulder Girdle and Anterior Limb of Drepanosaurus Unguicaudatus

With 12 figures The shoulder girdle and anterior limb of Drepanosaurus unguicaudatus (Reptilia, Neodiapsida) from the upper Triassic (Norian) Downloaded from https://academic.oup.com/zoolinnean/article/111/3/247/2691415 by guest on 27 September 2021 of Northern Italy SILVIO RENESTO Dipartimento di Scienze della Terra, Universita degli Studi, Via Mangiagalli 34, I-20133 Milano, Italy Received January 1993, accepted for publication February 1994 A reinvestigation of the osteology of the holotype of Drepanosaurus unguicaudatus Pinna, 1980 suggests that in earlier descriptions some osteological features were misinterpreted, owing to the crushing of the bones and because taphonomic aspects were not considered. The pattern of the shoulder girdle and fore-limb was misunderstood: the supposed interclavicle is in fact the right scapula, and the bones previously identified as coracoid and scapula belong to the anterior limb. The new reconstruction of the shoulder girdle, along with the morphology of the phalanges and caudal vertebrae, leads to a new hypothesis about the mode oflife of this reptile. Drepanosaurus was probably an arboreal reptile which used its enormous claws to scrape the bark from trees, perhaps in search of insects, just as the modern pigmy anteater (Cyclopes) does. Available diagnostic characters place Drepanosaurus within the Neodiapsida Benton, but it is impossible to ascribe this genus to one or other of the two major neodiapsid lineages, the Archosauromorpha and the Lepidosauromorpha.

We have incorporated, where possible, original observations of numerous taxa spread throughout the major tetrapod clades. A stem-based (total-group) definition of Tetrapoda is preferred over apomorphy- and node-based (crown-group) definitions. This definition is operational, since it is based on a formal character analysis. A PAUP* search using a recently implemented version of the parsimony ratchet method yields 64 shortest trees.

    Graellsia, 53: 111-175 (1997) DESCRIPCIÓN DE NUEVAS ESPECIES ANIMALES DE LA PENÍNSULA IBÉRICA E ISLAS BALEARES (1978-1994): TENDENCIAS TAXONÓMICAS Y LISTADO SISTEMÁTICO M. Esteban (*) y B. Sanchiz (*) RESUMEN Durante el periodo 1978-1994 se han descrito cerca de 2.000 especies animales nue- vas para la ciencia en territorio ibérico-balear. Se presenta como apéndice un listado completo de las especies (1978-1993), ordenadas taxonómicamente, así como de sus referencias bibliográficas. Como tendencias generales en este proceso de inventario de la biodiversidad se aprecia un incremento moderado y sostenido en el número de taxones descritos, junto a una cada vez mayor contribución de los autores españoles. Es cada vez mayor el número de especies publicadas en revistas que aparecen en el Science Citation Index, así como el uso del idioma inglés. La mayoría de los phyla, clases u órdenes mues- tran gran variación en la cantidad de especies descritas cada año, dado el pequeño núme- ro absoluto de publicaciones. Los insectos son claramente el colectivo más estudiado, pero se aprecia una disminución en su importancia relativa, asociada al incremento de estudios en grupos poco conocidos como los nematodos. Palabras clave: Biodiversidad; Taxonomía; Península Ibérica; España; Portugal; Baleares. ABSTRACT Description of new animal species from the Iberian Peninsula and Balearic Islands (1978-1994): Taxonomic trends and systematic list During the period 1978-1994 about 2.000 new animal species have been described in the Iberian Peninsula and the Balearic Islands.

  • Radial Symmetry Or Bilateral Symmetry Or "Spherical Symmetry"
    Symmetry in biology is the balanced distribution of duplicate body parts or shapes. The body plans of most multicellular organisms exhibit some form of symmetry, either radial symmetry or bilateral symmetry or "spherical symmetry". A small minority exhibit no symmetry (are asymmetric). In nature and biology, symmetry is approximate. For example, plant leaves, while considered symmetric, will rarely match up exactly when folded in half. Radial symmetry These organisms resemble a pie where several cutting planes produce roughly identical pieces. An organism with radial symmetry exhibits no left or right sides. They have a top and a bottom (dorsal and ventral surface) only. Animals Symmetry is important in the taxonomy of animals; animals with bilateral symmetry are classified in the taxon Bilateria, which is generally accepted to be a clade of the kingdom Animalia. Bilateral symmetry means capable of being split into two equal parts so that one part is a mirror image of the other. The line of symmetry lies dorso-ventrally and anterior-posteriorly. Most radially symmetric animals are symmetrical about an axis extending from the center of the oral surface, which contains the mouth, to the center of the opposite, or aboral, end. This type of symmetry is especially suitable for sessile animals such as the sea anemone, floating animals such as jellyfish, and slow moving organisms such as sea stars (see special forms of radial symmetry). Animals in the phyla cnidaria and echinodermata exhibit radial symmetry (although many sea anemones and some corals exhibit bilateral symmetry defined by a single structure, the siphonoglyph) (see Willmer, 1990).
