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.

Zattara, [email protected] Abstract Animals vary widely in their ability to regenerate, suggesting that regenerative abilities have a rich evolutionary history. However, our understanding of this history remains limited because regeneration ability has only been evaluated in a tiny fraction of species. Available comparative regeneration studies have identified losses of regenerative ability, yet clear documentation of gains is lacking. We surveyed regenerative ability in 34 species spanning the phylum Nemertea, assessing the ability to regenerate heads and tails either through our own experiments or from literature reports. Our sampling included representatives of the 10 most diverse families and all three orders comprising this phylum.

  • About the Book the Format Acknowledgments
    About the Book For more than ten years I have been working on a book on bryophyte ecology and was joined by Heinjo During, who has been very helpful in critiquing multiple versions of the chapters. But as the book progressed, the field of bryophyte ecology progressed faster. No chapter ever seemed to stay finished, hence the decision to publish online. Furthermore, rather than being a textbook, it is evolving into an encyclopedia that would be at least three volumes. Having reached the age when I could retire whenever I wanted to, I no longer needed be so concerned with the publish or perish paradigm. In keeping with the sharing nature of bryologists, and the need to educate the non-bryologists about the nature and role of bryophytes in the ecosystem, it seemed my personal goals could best be accomplished by publishing online. This has several advantages for me. I can choose the format I want, I can include lots of color images, and I can post chapters or parts of chapters as I complete them and update later if I find it important. Throughout the book I have posed questions. I have even attempt to offer hypotheses for many of these. It is my hope that these questions and hypotheses will inspire students of all ages to attempt to answer these. Some are simple and could even be done by elementary school children. Others are suitable for undergraduate projects. And some will take lifelong work or a large team of researchers around the world. Have fun with them! The Format The decision to publish Bryophyte Ecology as an ebook occurred after I had a publisher, and I am sure I have not thought of all the complexities of publishing as I complete things, rather than in the order of the planned organization.

Turbellarian research was largely ignored in Australia, apart from some early interest at the turn of the 19th century. The modern study of this mostly free-living branch of the phylum Platyhelminthes was led by Lester R.G. Cannon of the Queensland Museum. A background to the study of turbellarians is given particularly as it relates to the efforts of Cannon on symbiotic fauna, and his encouragement of visiting specialists and students.

The Nemerteans are named for Nemertes, one of the Nereids, sea-nymph of Greek mythology. They are commonly looked upon related to the Turbellaria and were formerly included in them, but the fact that they possess a complete digestive system with anus and also a blood vascular system makes them higher in organization than the Turbellaria. However, presence of a protrusible proboscis with a separate proboscis pore, other than mouth, is the most characteristic feature of the phylum. Almost all nemerteans are free living, bottom-dwelling, marine animals. Few commensal and parasitic species have been described. Nemertopsis actinophila is a slender form living beneath the pedal disc of sea anemones. Carcinonmertes may be found on gills and egg masses of crabs. Some species of Tetrastemma live in the branchial cavity of tunicates. Only few exibit commensal mode of life eg. Gonomertes parasitica is a commensal species found on crustaceans,.

  • Species Composition of the Free Living Multicellular Invertebrate Animals
    Historia naturalis bulgarica, 21: 49-168, 2015 Species composition of the free living multicellular invertebrate animals (Metazoa: Invertebrata) from the Bulgarian sector of the Black Sea and the coastal brackish basins Zdravko Hubenov Abstract: A total of 19 types, 39 classes, 123 orders, 470 families and 1537 species are known from the Bulgarian Black Sea. They include 1054 species (68.6%) of marine and marine-brackish forms and 508 species (33.0%) of freshwater-brackish, freshwater and terrestrial forms, connected with water. Five types (Nematoda, Rotifera, Annelida, Arthropoda and Mollusca) have a high species richness (over 100 species). Of these, the richest in species are Arthropoda (802 species – 52.2%), Annelida (173 species – 11.2%) and Mollusca (152 species – 9.9%). The remaining 14 types include from 1 to 38 species. There are some well-studied regions (over 200 species recorded): first, the vicinity of Varna (601 spe- cies), where investigations continue for more than 100 years. The aquatory of the towns Nesebar, Pomorie, Burgas and Sozopol (220 to 274 species) and the region of Cape Kaliakra (230 species) are well-studied. Of the coastal basins most studied are the lakes Durankulak, Ezerets-Shabla, Beloslav, Varna, Pomorie, Atanasovsko, Burgas, Mandra and the firth of Ropotamo River (up to 100 species known). The vertical distribution has been analyzed for 800 species (75.9%) – marine and marine-brackish forms. The great number of species is found from 0 to 25 m on sand (396 species) and rocky (257 species) bottom. The groups of stenohypo- (52 species – 6.5%), stenoepi- (465 species – 58.1%), meso- (115 species – 14.4%) and eurybathic forms (168 species – 21.0%) are represented.

EvoDevo 2014, 5:37 http://www.evodevojournal.com/content/5/1/37 RESEARCH Open Access Cellular dynamics during regeneration of the flatworm Monocelis sp. (Proseriata, Platyhelminthes) Johannes Girstmair1,2, Raimund Schnegg1,3, Maximilian J Telford2 and Bernhard Egger1,2* Abstract Background: Proseriates (Proseriata, Platyhelminthes) are free-living, mostly marine, flatworms measuring at most a few millimetres. In common with many flatworms, they are known to be capable of regeneration; however, few studies have been done on the details of regeneration in proseriates, and none cover cellular dynamics. We have tested the regeneration capacity of the proseriate Monocelis sp. by pre-pharyngeal amputation and provide the first comprehensive picture of the F-actin musculature, serotonergic nervous system and proliferating cells (S-phase in pulse and pulse-chase experiments and mitoses) in control animals and in regenerates. Results: F-actin staining revealed a strong body wall, pharynx and dorsoventral musculature, while labelling of the serotonergic nervous system showed an orthogonal pattern and a well developed subepidermal plexus. Proliferating cells were distributed in two broad lateral bands along the anteroposterior axis and their anterior extension was delimited by the brain. No proliferating cells were detected in the pharynx or epidermis. Monocelis sp. was able to regenerate the pharynx and adhesive organs at the tip of the tail plate within 2 or 3 days of amputation, and genital organs within 8 to 10 days.

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.
