MITRA* * Parasitology Laboratory, Department of Zoology, University of Kalyani, Kalyani-74I 235, West Bengal, India INTRODUCTION Soil animals may play a range of roles in vineyards. Decomposers (some of which are opportunistic herbivores) are important in nutrient dynamics, because by reducing organic matter to its constituents, they liberate nutrients usable by grapevines. Earthworms are only part of the complex of organisms termed "decomposers" in agroecology. As noted by Charles Darwin in his 1882 classic, The Fonnation of Vegetable Mould Through the Action of Earthworms with Observations on Their Habits (Werner, 1990), earthworms process huge quantities of plant litter and help to convert it into rich topsoil, liberating nutrients for renewed plant growth. More recent studies show that earthworms can help to reduce soil compaction, improving permeability and aeration. Earthworms do this through burrowing activities, ingestion of soil along with plant debris, and subsequent excretion of casts. Upon drying, these casts form water-stable soil aggregates. These aggregates are clumps of soil particles bound together by organic compounds, and their presence helps to improve soil structure, retain nutrients that might otherwise be leached, and reduce the threat of erosion (Lee, 1985). Earthworms are increasingly recognized as indicators of agro-ecosystem health and as important tools for ensuring soil improvement and efficient nutrient cycling. In India, due to continuous biodiversity surveys of earthworms number of new species IS increasing day by day, although in comparison to more than 3000 global species (Stephenson, 1923), the number of Indian species is far less (only 390). -

Annelida: Oligochaeta: Naididae) Geographical Distribution from Southern Caspian Sea Basin, Mazandaran Province - Iran
Iranian Journal of Fisheries Sciences 20(1) 109-128 2021 DOI: 10.22092/ijfs.2021.351016.0 Research Article New report for Pristinella jenkinae Stephenson, 1931 (Annelida: Oligochaeta: Naididae) geographical distribution from Southern Caspian Sea basin, Mazandaran province - Iran Erfani M.1* Received: May 2020 Accepted: November 2020 Abstract Pristinella jenkinae (Stephenson, 1931) is a freshwater cosmopolitan oligochaete. This species was found during limnological investigation in two rivers alongside Iranian coasts and has not been previously reported from Iran‟s freshwater fauna and Southern Caspian Sea basin. The specimens of P. jenkinae were collected bimonthly from Cheshmehkileh and Sardabrood rivers and estuaries (river mouth) using a Van Veen grab (0.03 m2) and Surber (0.1 m2, 0.2 mm-mesh size) samplers at three stations in each estuary (S1: riverine, S2: estuary and S3: marine ecosystem) with three replicates from November 2014 through September 2015. Results of temporal distribution showed that the highest and lowest density and biomass of this species were in January (102.3±68.3 ind m-2 and 0.075±0.034g m-2) and in September (24.4±12.3 ind m-2 and 0.020±0.005g m-2), respectively which were significantly different (N=57, t=0.99, p<0.05). Spatial distribution of P. jenkinae among sampling stations (S1, S2 and S3) showed significant differences (N=57, t=0.99, p<0.05). Freshwater stations (S1) within the river showed Downloaded from jifro.ir at 17:51 +0330 on Friday September 24th 2021 higher density and biomass (112.1±64.8 ind m-2 and 0.082±0.035g m-2) than semi- brackish stations (S2) within the estuary (18.8±10.3 ind m-2 and 0.013±0.005g m-2). -

Fazlul Awal Mollah Department of Fisheries Biology and Genetics, Faculty of Fisheries, Bangladesh Agricultural University, Mymensingh-2202, Bangladesh *Corresponding author: Mariom, Department of Fisheries Biology and Genetics, Faculty of Fisheries, Bangladesh Agricultural University, Mymensingh-2202, Bangladesh. E-mail: [email protected] Received: 12 January 2016/Accepted: 17 January 2016/ Published: 31 March 2016 Abstract: Tubificids are aquatic oligochaete worms (F- Naididae, O- Haplotaxida, P- Annelida) distributed all over the world. The worms are very important as they are used as live food for fish and other aquatic invertebrates. A step was taken to identify the genera of tubicifid worms that exist in Mymensingh district, Bangladesh on the basis of some external features including the shape of their anterior (prostomium) and posterior end, number of body segment and arrangement of setae. The study result indicated the existence of three genera among the tubificid worms. These were Tubifex, Limnodrilus and Aulodrilus. All these three genera possessed a cylindrical body with a bilateral symmetry formed by a series of metameres. The number of body segments ranged from 34 to 120 in Tubifex, 50 to 87 in Limnodrilus, and 35 to 100 in Aulodrilus. In Tubifex, the first segment, with the prostomium, was round or triangular bearing appendages, whereas, in Limnodrilus and Aulodrilus, the prostomium without appendages was triangular and conical, respectively. -

Chapter XXV —Class Oligochaeta
Chapter XXV —Class Oligochaeta (Aquatic Worms)- Phylum Annelida Oligochaetes are common in most freshwater habitats, but they are often ignored by freshwater biologists because they are thought to be extraordinarily difficult to identify. The extensive taxo- nomic work done since 1960 by Brinkhurst and others, however, has enabled routine identifica- tion of most of our freshwater oligochaetes from simple whole mounts. Some aquatic worms closely resemble terrestrial earthworms while others can be much narrower or thread-like. Many aquatic worms can tolerate low dissolved oxygen and may be found in large numbers in organi- cally polluted habitats. Aquatic worms can be distinguished by: (Peckarsky et al., 1990) • Body colour may be red, tan, brown or black. • Cylindrical, thin (some are very thin), segmented body may be upto 5 inches. • May have short bristles or hairs (setae) that help with movement (usually not visible). • Moves by stretching and pulling its body along in a worm-like fashion. Four families in the orders Tubificida and Lumbriculida are common in freshwater in northeastern North America: the Tubificidae, Naididae, Lumbriculidae, and Enchytraeidae. In addition, fresh- water biologists sometimes encounter lumbricine oligochaetes (order Lumbricina; the familiar earthworms), haplotaxid oligochaetes (order Haplotaxida; rare inhabitants of groundwater), Aeolosoma (class Aphanoneura; small worms once classified with the oligochaetes), and Manayunkia speciosa (class Polychaeta) in waters of northeastern North America. (Peckarsky et al., 1990). The two families, Naididae and Tubificidae form 80 to 100% of the annelid communi- ties in the benthos of most streams and lakes at all trophic levels. They range in size from 0.1 cm in Naididae to 3 or 4 cm in relaxed length in Lumbricidae, the family that contains the earth- worms. -

Most species in the genus Dero have unique morphological characters including a branchial fossa and/or gills at the posterior end of the body. The genus Allonais has no eyes unlike its close relative the genus Nais. Of these genera, one species of Dero, D. obtusa, was recently reported in Korea. However, the genus Allonais has not been recorded in Korea. Here, we report Dero dorsalis Ferronière, 1899 and Allonais pectinata (Stephenson, 1910) with a diagnosis and illustrations.

Both series were founded by Dr. Bryant Walker, Mr. Bradshaw H. Swales, and Dr. W. W. Newcomb. Occasionally the Museum publishes contributions outside of these series. Beginning in 1990 these are titled Special Publications and Circulars and each is sequentially numbered. All submitted manuscripts to any of the Museum’s publications receive external peer review. The Occasional Papers, begun in 1913, serve as a medium for original studies based principally upon the collections in the Museum. They are issued separately. When a sufficient number of pages has been printed to make a volume, a title page, table of contents, and an index are supplied to libraries and individuals on the mailing list for the series. The Miscellaneous Publications, initiated in 1916, include monographic studies, papers on field and museum techniques, and other contributions not within the scope of the Occasional Papers, and are published separately. Each number has a title page and, when necessary, a table of contents. A complete list of publications on Mammals, Birds, Reptiles and Amphibians, Fishes, I nsects, Mollusks, and other topics is available.
