First of all I wish to thank my adviser, Dr. N. W. Britt, for his help and encouragement. My gratitude is extended to associates at the Franz Theodore Stone Laboratory, especially to the Director, Dr. L. S, Putman, and Dr. J. Hubschman. Others there assisted me in obtaining animals used in the study. To them I am grateful. X should like to express my appreciation to the staff of the Water Resources Center who provided facilities and equipment used in this project as well as technical advice. The assistance of Professor W. D. Sheets, Dr. K. S. Shumate, and Mr. John McConnell is particularly appreciated. To Dr. W. Collins, Dr. R. Skavaril, Dr. S. S. Y. Young, Dr. P. R. Dunlap and Mr. A.

The species was found at three subtidal stations in the Schelde estuary in Belgium, where it was probably introduced from the Americas. We provide an overview of the species’ nomenclature, diagnostics, distribution, and ecology. Bratislavia dadayi is one of 11 non-indigenous annelids currently known to occur in the Schelde estuary. Key words: alien species; Annelida; Clitellata; Oligochaeta; Polychaeta; Belgium Introduction Annelids, and oligochaetes in particular, are a less-studied group, often overlooked when Over the last 150 years, the number of non- considering alien species. Yet the best studied native species turning up in areas far from their Annelid species, Lumbricus terrestris (L., 1758), original range has increased significantly (Bax et is now considered a widespread invasive species al.

Email: [email protected] Abstract Thirty-eight species of oligochaetes (Annelida, Clitellata) belonging to five families were recorded from profundal bottoms of 50 freshwater lakes on Japanese islands. They were mostly widely distributed species, and the composition of fauna is basically explained by the scheme of Timm (2012), with parallel replacement of European species. Oxygen, temperature and surrounding fauna could be main factors determining the profundal fauna in the lakes. The lumbriculids (Styloscolex japonicus, Yamaguchia toyensis and Lumbriculus variegatus), haplotaxids (Haplotaxis gordioides) and enchytraeids (Marionina klaskisharum) were restricted to several deep and oligotrophic lakes located in Hokkaido and northern Honshu, where Rhyacodrilus komarovi often accompanied them. Limnodrilus hoffmeisteri was the commonest species, occurring irrespective of the trophic status and bottom temperature of the lake. Tubifex tubifex also occurred in wide trophic scale, but it has never been found in shallow eutrophic lakes where the bottom temperature exceeds 15°C, where L. hoffmeisteri,

  • Life Forms in Oligochaeta: a Literature Review
    Life forms in Oligochaeta: a literature review Tarmo Timm Abstract. The main life forms among the Oligochaeta s.l. (= Clitellata) and the related poly- chaetes are: aquatic (freshwater and marine) sediment-dwellers, inhabitants of the macrovegeta- tion, large and small soil-dwellers, and carnivores. The vegetation-dwellers (Naididae, Pristinidae and Opistocystidae) reproduce mostly in an asexual way; some of them have an ability to swim and posses eyes. A convergent group to the naidid oligochaetes is the aphanoneuran genus Aeolo- soma. The smaller Enchytraeidae, and the larger “earthworms” (= Megadrili) Crassiclitellata and Moniligastridae, live in the terrestrial soil. Some Enchytraeidae and Crassiclitellata are secondari- ly aquatic while some (generally aquatic) tubificids can facultatively live in the soil. Carnivory (as parasitism, commensalism or predation) has been developed in separate genera of several fami- lies. A large clade, including the Hirudinea, the Acanthobdellidae and the Branchiobdellidae, is highly adapted for carnivory (suckers, jaws, loss of chaetae, etc.). Two evolutionary trends are evident in different clades: reduction in chaetal number from indefinite to two per bundle, or to complete loss of chaetae, and reduction of the upper tooth in the originally bifid sigmoid chaetae. External gills have appeared at least in four independent cases. There exist many convergencies in the mode of life and morphology of separate Oligochaeta and related “oligochaetoid” polychaetes. Key words. Oligochaeta, Clitellata, Polychaeta, life forms, characters, convergency. Introduction The presented brief review deals with survey of the phenotypes and convergencies among the Oligochaeta and some of their phylogenetic relatives. The subclass Oligochaeta is a paraphyletic taxon constituting the bulk of species included in the class Clitellata; in the phylogenetical sense, it is identical with the Clitellata.

  • A New Record of Three Tubificid Species (Annelida: Oligochaeta) from Al-Hawiezah Marsh, Iraq
    Mesopot. J. Mar. Sci., 2011, 26 (2): 114 - 121 A new record of three tubificid species (Annelida: Oligochaeta) from Al-Hawiezah marsh, Iraq H.J. Jaweir College of Science for Women, University of Baghdad e-mail: [email protected] (Received: 8 March 2011 - Accepted: 29 October 2011) Abstract - This paper reports the first record of three species of aquatic oligochaete worms from Al-Hawiezah marsh, south of Iraq. It was evident that the specimens belonged to the family: Naididae, subfamily: Tubificinae, Species: Aulodrilus pigeuti; Embolocephalus velutinus and Limnodrilus profundicola. A. pigueti is a new record for Iraqi fauna. The study includes the identification and description of these species together with photographic illustrations of chaetal types of each species. Introduction Tubificid worms are the most common aquatic Oligochaeta in freshwater habitats. The Family Naididae, subfamily Tubificinae, with more than 1000 described species; include 582 species are considered as freshwater inhabitants (Martin et al., 2008). They are most commonly found in soft, organic matter rich, sediments. Several species characteristically live at sites that receive organic pollution, as they are known to tolerate anoxic condition. Some species are deposit feeders utilizing organic detritus and its associated microflora. These Oligochaetes are hermaphrodite and reproduce by cross-fertilization, while a few species of them may reproduce asexually by architomy (Timm, 2009). All Tubificid worms can be easily identified depending on external features. They possess no eyes and the prostomium contains no proboscis. Chaetae are the most important features for identification. These are widely varied between different species. In general the chaetae are of two types, hair chaetae and sigmoid chaetae.
