Species Composition And Distribution

The species composition and distribution patterns of Nereididae (Annelida: Polychaeta) from the north coast of Gulf of Oman were investigated. Specimens were collected from ten intertidal sites along the Iranian coast, including mangrove, muddy, boulder and rocky, coral and sandy-rocky shore habitats. Eight species of Nereididae were identified: Leonnates decipiens Fauvel, Nereis coutieri Gravier, Neanthes deplanata Mohammad, Perinereis nuntia (Savigny), Perinereis heterodonta Gravier, Perinereis cultrifera (Grube), Perinereis horsti Gravier and Pseudonereis trimaculata Horst. The eight species are redescribed and two Perinereis species, P. heterodonta and P. horsti, currently junior synonyms of P. nuntia and P. vancaurica (Ehlers) respectively, are raised from synonymy. All reported species are new records for the Gulf of Oman, bringing the known total number of species in the family to twelve; P. trimaculata is also a new record for the Arabian Sea–Arabian Gulf region. Nereidid diversity within the region is comparable to other Indo-Pacific coastal regions, and higher than other parts of the world.

Calathiscus tantillus new genus & new species (Scleractinia, Poritidae) is described from several specimens collected along the north coast of the Sultanate of Oman and Masirah Island. The zooxanthellate genus has a massive growth form, although colonies remain very small (< 40 mm). The skeletal characteristics are intermediate between Porites and Goniopora, with calices averaging 1.7 mm in diameter. The polyps, fully extended during the day in most specimens, have a long tubular column topped by a wide conical oral disc surrounded by 15 22 tentacles. The characteristics of this new species and genus are discussed in relation to other genera in the family: Porites, Goniopora, Stylarea, Alveopora and Poritipora.

The infauna of Chabahar Bay (Iranian Coast of the Gulf of Oman) was investigated using shallow water (less than 10 m) grab-samples between June 2013 and March 2014. The magelonid fauna of these samples was studied and prioritized, with four species being present:M. fauchaldisp. nov.,M. symmetrica, M.cf.cinctaandM. crenulifrons. The new species differs from all known magelonid species within the Persian Gulf region in possessing polydentate abdominal hooks. A fifth species, currently undescribed, was also found. The validity ofM. pulchellaoriginally described from Kuwait is discussed in light of its closeness toM. crenulifrons. The main distinguishing feature between the two species is the presence or absence of crenulation of the anterior prostomial margin, a character shown to be variable inM. crenulifrons. Although differences between the type specimens of both species suggestsM. pulchellato be a valid species, examination of further material and DNA analysis is needed.

The Impact

Power and desalination plants are very important in the Arabian Gulf region to provide water and electricity. Abu Dhabi, United Arab Emirates has a number of power and desalination plants. One of these plants is Umm Al Nar plant. It is located inside a lagoon north of Abu Dhabi Island, which is the North Lagoon. Hydrodynamic study was carried out to investigate the impact of constructing a temporary closure dam in the tidal water near the plant intake on the flow pattern and the recirculation of effluent discharges from the outfall to the intake of the plant. The effect of the proposed dam on the mangroves in the vicinity of the plant was investigated. Two dimension hydrodynamic numerical flow model simulates the study area was used in the study. The hydrodynamic and environmental impact of the proposed dam was evaluated by comparing the results of the model computations with and without the dam simulation.

<em>Abstract.—</em>The Mid-Atlantic Ridge of the North Atlantic is inhabited by at least 16 macrourid species in 9 genera. The species composition and distribution patterns are analysed based on bottom trawl catches in the depth range 985 to 3461m conducted on the 2004 MAR-ECO expedition between the Azores and the southern Reykjanes Ridge. Some of the species, e.g. roundnose grenadier <em>Coryphaenoides rupestris</em>, <em>C. brevibarbis </em>and abyssal grenadier <em>C. armatus, </em>rank among the most abundant demersal fishes on the ridge or in the deep axial valleys or fracture zones, while others are uncommon or rare. While a few species have apparently restricted northerly or southerly distributions, most are widespread. Among common species that occur along the entire ridge section investigated, there are indications of structuring by depth of occurrence.

First Time

The family Macrophthalmidae Dana, 1851, is one of the best represented brachyuran groups in intertidal habitats in the Persian Gulf. Nine species from two subfamilies are reported from the gulf and the adjacent Gulf of Oman, mainly inhabiting intertidal soft substrates. The subfamily Ilyograpsinae Števcic, 2005, is represented by Ilyograpsus rhizophorae Barnard, 1950, erroneously recorded as I. paludicola (Rathbun, 1909). Eight species of the subfamily Macrophthalminae Dana, 1851, have been recorded from the area, all belonging to Macrophthalmus Desmarest, 1823. Of these, M. sinuspersici Naderloo & Türkay, 2010, has recently been described and is the only species of the genus occurring on rocky shores. Macrophthalmus graeffei A. Milne-Edwards, 1873, occurs in subtidal water and is hereby recorded for the first time from the northern Indian Ocean. The remaining six species, M. dentipes Lucas, 1836, M. depressus Rüppell, 1830, M. grandidieri A. Milne-Edwards, 1867, M. laevis A. Milne-Edwards, 1867, M. serenei Takeda & Komai, 1991, and M. sulcatus H. Milne-Edwards, 1852, are important elements of the intertidal soft bottom communities. An identification key for the genus Macrophthalmus in the area is provided, and the geographical distribution of the family is briefly discussed.

The Town

In 1993 some among the Sikkanese population of the town of Maumere on the north coast of Flores in eastern Indonesia attended a ritual to reconcile the members of two branches of the family of the rajas of Sikka, a dynasty that had once ruled the district. The two branches had fallen out over differences in opinion about the last succession to the office of raja a few years before the end of the rajadom in the late 1950s. A description of the ritual, which was conducted in an urban rather than a village setting, and an analysis of the performance demonstrate much about the persistence of elements of the old Sikkanese religion in modern Sikkanese society. The contemporary Sikkanese are Christians and the regency of Sikka is part of the modern Indonesian nation-state.

Primitive Member

Trypanosoma balbianii , Certes, is a primitive member of the family of the Trypanosomidæ, and occurs in great numbers as a parasite in the gut of the oyster, where it may be present, either swimming freely in the fluid contents or enclosed within the crystalline style, when this structure is present. The species has been worked at by Certes and Lustrae, the latter of whom describes the presence of an undulating membrane and the external features of the process of division. The nucleus is, however, described by neither author. The material used in prosecuting this research was obtained from oysters fished from the Adriatic Sea, off the coast of Rovigno, but the parasite also occurs in the oysters of Schleswig-Holstein and the north coast of France. This distribution is thus a wide one. The research has been carried out under the guidance of Dr. von Prowazek, my great indebtedness to whom I here take the opportunity of expressing.

A New Species

The marine intertidal zone constitutes one of the most interesting ecosystems on the earth. Oribatid mites of the family Fortuyniidae inhabit marine intertidal habitats in the tropical and subtropical coasts of the world. This family has not been known from Iran until now. The present work deals with a new oribatid species of this family found at the coast of the Gulf of Oman, southeastern Iran, from algae in the intertidal zone of a rocky shore. Fortuynia iranica sp. nov., is described from littoral environments of Chabahar Beach, Sistan and Baluchistan province based on adult and juvenile (deutonymph) stages. The new species is characterized by the presence of both prodorsal external and internal channels; fourteen smooth, thin and long notogastral setae, with a light-colored porose spot in the insertions, c3 completely absent; sensilli with a very slightly oriented head; glove-like lenticulus; epimeral setation 3-1-3-2 and presence of one pair of aggenital setae. An updated diagnostic key to the adults of known species of Fortuynia van der Hammen, 1960 is given.

Jepara has many handicrafts. One of them is monel craft which requires special skills, family business management and from generation to generation. The traditional management seems to have survived in 2010-2015. This is due to the skill in pursuing monel craft, studied non-formally, through learning the way of apprenticeship. In production activities, monel craft is also followed by students who are also active participants who directly learn and practice at the location of the craft. The development of monel handicrafts in Jepara experienced periods that could be said to be increasing. Starting from the family business, it is not a barrier to the development of monel crafts that grow from one family to another. The business network carried out more utilizes social gatherings that exist in the village community, including the tradition of mutual friendship between residents, neighborhood association social meetings and recitation. This container is used as a means to exchange information about the development of craft models that are in demand by the market and its marketing information. The marketing method has not yet developed, because it relies more on the local market while benefiting from the existence of Jepara as a tourist city.

Abundance And Diversity

The knowledge on the hard bottom polychaete assemblages in the Northern Adriatic Sea, a Mediterranean region strongly affected by environmental pressures, is scarce and outdated. The objective of this paper was to update the information on polychaete diversity and depict their patterns of natural spatial variation, in relation to changes in algal coverage at increasing depth. Hard bottom benthos was quantitatively sampled by scraping off the substrate from three stations at Sveti Ivan Island (North Adriatic) at three depths (1.5 m, 5 m and 25 m). Polychaete fauna comprised 107 taxa (the majority of them identified at species level) belonging to 22 families, with the family Syllidae ranking first in terms of number of species, followed by Sabellidae, Nereididae, Eunicidae and Serpulidae. Considering the number of polychaete species and their identity, the present data differed considerably from previous studies carried out in the area. Two alien species, Lepidonotus tenuisetosus, which represented a new record for the Adriatic Sea, and Nereis persica, were recorded. The highest mean abundance, species diversity and internal structural similarity of polychaete assemblages were found at 5 m depth, characterised by complex and heterogeneous algal habitat. The DISTLM forward analysis revealed that the distribution of several algal taxa as well as some algal functional-morphological groups significantly explained the observed distribution patterns of abundance and diversity of polychaete assemblages. The diversity of the North Adriatic hard bottom polychaete fauna is largely underestimated and needs regular updating in order to detect and monitor changes of benthic communities in the area.
