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.

New Zealand's Genetic Diversity
1.13 NEW ZEALAND’S GENETIC DIVERSITY NEW ZEALAND’S GENETIC DIVERSITY Dennis P. Gordon National Institute of Water and Atmospheric Research, Private Bag 14901, Kilbirnie, Wellington 6022, New Zealand ABSTRACT: The known genetic diversity represented by the New Zealand biota is reviewed and summarised, largely based on a recently published New Zealand inventory of biodiversity. All kingdoms and eukaryote phyla are covered, updated to reﬂ ect the latest phylogenetic view of Eukaryota. The total known biota comprises a nominal 57 406 species (c. 48 640 described). Subtraction of the 4889 naturalised-alien species gives a biota of 52 517 native species. A minimum (the status of a number of the unnamed species is uncertain) of 27 380 (52%) of these species are endemic (cf. 26% for Fungi, 38% for all marine species, 46% for marine Animalia, 68% for all Animalia, 78% for vascular plants and 91% for terrestrial Animalia). In passing, examples are given both of the roles of the major taxa in providing ecosystem services and of the use of genetic resources in the New Zealand economy. Key words: Animalia, Chromista, freshwater, Fungi, genetic diversity, marine, New Zealand, Prokaryota, Protozoa, terrestrial. INTRODUCTION Article 10b of the CBD calls for signatories to ‘Adopt The original brief for this chapter was to review New Zealand’s measures relating to the use of biological resources [i.e. genetic genetic resources.

Abstract Symsagittifera roscoffensis is a small marine worm found in the intertidal zone of sandy beaches around the European shores of the Atlantic. S. roscoffensis is a member of the Acoelomorpha, a group of flatworms formerly classified with the Platyhelminthes, but now recognised as Xenacoelomorpha, a separate phylum of disputed affinity.

CAPÍTULO 7 Phylum Dicyemida Francisco Brusa Y Lisandro Negrete
CAPÍTULO 7 Phylum Dicyemida Francisco Brusa y Lisandro Negrete "Desde su descubrimiento han constituido un rompecabezas taxonómico". LIBBIE H. HYMAN, THE INVERTEBRATES (1940) El phylum Dicyemida tradicionalmente se asociaba a los ortonéctidos, que parasitan varios grupos de in- vertebrados marinos (“turbelarios”, nemertinos, poliquetos, moluscos gasterópodos y bivalvos, ofiuros y ascidias), y se los incluía en el phylum Mesozoa, por su grado de organización intermedio entre los proto- zoos y metazoos. Actualmente, debido a diferencias en su anatomía y en el ciclo de vida se los reconoce como pertenecientes a dos phyla, Dicyemida y Orthonectida. Los diciémidos son un grupo de pequeños animales vermiformes que parasitan los apéndices renales de moluscos cefalópodos. Presentan especificidad parasitaria y generalmente un individuo hospedador puede albergar más de una especie parásita. Se reconocen 112 especies válidas distribuidas en nueve géneros, cinco de los cuales son monoespecíficos (Catalano, 2012). Los diciémidos están mejor representados en el hemisferio norte, mientras que se conocen pocos registros en el hemisferio sur; este sesgo podría deberse a los escasos estudios en esta región. Son animales muy sencillos con el cuerpo constituido por pocas células (menos de 40), sin tejidos ni órganos. No obstante se ha reportado la presencia de uniones intercelulares entre distintas células en los individuos de los diferentes estadios del ciclo de vida. Se ha observado la pre- sencia de zónula adherens, mácula adherens y uniones gap. Si bien no se han encontrado componentes extracelulares formando una lámina basal o fibras de colágeno, sí se ha reportado la presencia de fibronec- tina y colágeno tipo IV con patrones de distribución similares a los de la lámina basal (Czaker y Janssen, 1998; Czaker, 2000).

Abstract Background: In order to increase the weak database concerning the organogenesis of Acoela – a clade regarded by many as the earliest extant offshoot of Bilateria and thus of particular interest for studies concerning the evolution of animal bodyplans – we analyzed the development of the musculature of Symsagittifera roscoffensis using F-actin labelling, confocal laserscanning microscopy, and 3D reconstruction software. Results: At 40% of development between egg deposition and hatching short subepidermal fibres form. Muscle fibre development in the anterior body half precedes myogenesis in the posterior half. At 42% of development a grid of outer circular and inner longitudinal muscles is present in the bodywall.

Lophotrochozoans represent a superphylum that is crucial to our understand- ing of bilaterian evolution. However, given the inconsistency of molecular and morphological data for these groups, their ori- gins have been unclear. Here, we present draft genomes of the nemertean Notospermus geniculatus and the phoronid Phoronis australis, together with transcriptomes along the adult bodies. Our genome-based phylogenetic analyses place Nemertea sis- ter to the group containing Phoronida and Brachiopoda. We show that lophotrochozoans share many gene families with deu- terostomes, suggesting that these two groups retain a core bilaterian gene repertoire that ecdysozoans (for example, flies and nematodes) and platyzoans (for example, flatworms and rotifers) do not.
