  • NEW RECORDS OF INDOMYSIS NYBINI (BIJU & PANANPUNNAYIL, 2010) FROM THE SOUTH OF IRAQ

    MURTADA D. NASER, TALIB A. KHALAF, AMAAL GH. YASSER, HAIDER SH. DARWEESH

    Crustaceana. 01/2012; 85(3):379-383.

    In the present paper, we report new records of a recently described species, Indomysis nybini Biju & Pananpunnayil, 2010, from the south of Iraq. Our findings support suggestions that mysids identified as I. annandalei from Saudia Arabia (Murano, 1998) and Bahrain (Grabe et al., 2004) may be ref...

Our findings support suggestions that mysids identified as I. annandalei from Saudia Arabia (Murano, 1998) and Bahrain (Grabe et al., 2004) may be referred to I. nybini.
  • Invasive records of Eriocheir hepuensis Dai, 1991 (Crustacea: Brachyura: Grapsoidea: Varunidae): Implications and taxonomic considerations

    A non-ovigerous female mitten crab captured in Iraq on the 20th June 2005 was initially identified as Eriocheir sinensis H. Milne Edwards, 1853. More material has now been made available from Iraq and Kuwait and these specimens were compared with the extant type series of E. sinensis and E. hepuensi... [more] A non-ovigerous female mitten crab captured in Iraq on the 20th June 2005 was initially identified as Eriocheir sinensis H. Milne Edwards, 1853. More material has now been made available from Iraq and Kuwait and these specimens were compared with the extant type series of E. sinensis and E. hepuensis Dai, 1991. From this morphological study the Persian Gulf material was identified as the Hepu mitten crab, E. hepuensis. This is the first report of this mitten crab species outside its native range of southern China. However, because mitten crab taxonomy and systematics requires further clarification especially with respect to species of Eriocheir De Haan, 1835, the DNA of the Persian Gulf material was compared with a suite of GenBank COI sequences from various mitten crab taxa. The results of this extensive examination indicate that the Iraqi and Kuwaiti specimens are E. hepuensis and the DNA analysis indicates that mitten crabs can be assigned to three genera and six species; although the present study does discuss reports of hybridisation between three Eriocheir species associated with aquaculture. Also reported, and of concern, is that E. hepuensis may have been first collected about thirty years ago in Iraq and has now become well established within that country. As a consequence the Hepu mitten crab could, given its catadromy, disperse widely throughout the extensive riverine systems of the region.

[more] The Shatt Al-Arab is an important invasion gateway in West Asia. Protocols of the ALARM project were used for estimation of risk assessment of aquatic invasions. There are five global alien species with high invasiveness which are widespread among the region (Eriocheir sinensis, Macrobrachium nipponense, Palaemon elegans, Balanus amphitrite, and Potamorpyrgus antipodarum). Identification and analysis of invasion pathways within the region show a predominantly secondary natural spread of alien species and also the importance of navigation and canals for recent expansion of alien species. Five assessment units (Hareer region, Abu Al-Khaseeb, Al-Sindibad, Qurna, and Garmat Ali) have extremely high and one (Shatt Al-Basrah) has high biological contamination and risk of biological pollution. Alien species increase similarity of macrozoonbenthic communities (biotic homogenization). Among key drivers of biological invasions in this region, a special place is occupied by geopolitical conflict and competition for natural resources which form a unique man-made hydrological regime in the Mesopotamian rivers.

    Environmental monitoring and assessment. 12/2010; 181(1-4):175-82.

    In this study, a total of 120 fish specimens of common carp (Cyprinus carpio), were caught at four different stations in Shatt Al-Arab (Hareer, Garmat Ali, Al-Maqal and Abual-Khasib).

[more] In this study, a total of 120 fish specimens of common carp (Cyprinus carpio), were caught at four different stations in Shatt Al-Arab (Hareer, Garmat Ali, Al-Maqal and Abual-Khasib). The histological changes in the gills of fish were detected microscopically. Results show that the Shatt Al-Arab is polluted by some different sources of pollutants including power stations, paper industry, oil refineries, petrochemical industry, chemical fertilizer companies and the sewage system and overfishing and the application of pesticides. As a result of these analyses, histopathological changes in the gills of fish specimens, such as hyperplasia, loss of regular shape of secondary lamellae, separation of lamellar epithelium, clavate structure, atrophy of secondary gills lamellae, necrosis, dilation of lamellar capillaries, loss of secondary lamellae, fusion of secondary lamellae, edema, proliferation of cartilage in primary lamellae and curving of primary lamellae, were observed. The histopathological changes in fish gill samples from the Hareer region were much more prevalent than samples caught from other stations.

[more] Specimens of the fiddler crab Uca (Paraleptuca) sindensis were collected from the intertidal zones of Khor Al-Zubair, Basrah, Iraq in 2009. A literature review on the distribution of this species revealed that this is the first report of U. (P) sindensis from the Iraqi coast and only the third country in which this species has been recorded. A note on the morphological features of this species and a photograph is provided to confirm the identification of the crab.
  • First record of the New Zealand mud snail Potamopyrgus antipodarum (Gray 1843) from Iraq: the start of expansion to Western Asia?

  • The Camptandriidae of Iraq, with description of a new genus and notes on Leptochryseus Al-Khayat & Jones, 1996 (Crustacea: Decapoda: Brachyura)

    PETER K. L. NG, DWI LISTYO RAHAYU, MURTADA D. NASER

    Zootaxa. 01/2009;

    Three species of camptandriid crabs (Crustacea: Brachyura: Ocypodoidea) are reported from Iraq: Tylodiplax indica Alcock, 1900, Manningis arabicum (Jones & Clayton, 1983) and Nasima dotilliformis (Alcock, 1900), all new records for the country.

[more] Three species of camptandriid crabs (Crustacea: Brachyura: Ocypodoidea) are reported from Iraq: Tylodiplax indica Alcock, 1900, Manningis arabicum (Jones & Clayton, 1983) and Nasima dotilliformis (Alcock, 1900), all new records for the country. The taxonomy of the three species is treated in detail. Tylodiplax indica Alcock, 1900, is here referred to Opusia new genus, differing from Tylodiplax De Man, 1895, by numerous carapace and male gonopod characters. Manningis arabicum (Jones & Clayton, 1983) and Nasima dotilliformis (Alcock, 1900) are redescribed from the types or topotypic material, and more differences with allied genera recorded and discussed. An allied genus from Kuwait, Leptochryseus Al-Khayat & Jones, 1996, is shown to be a valid taxon. Nasima is shown to be very close to Leptochryseus, sharing important thoracic sternal, male abdominal and male first gonopod characters, differing only in carapace features and adults of Leptochryseus being sexually dimorphic in their chelipeds.

  • Assiminea mesopotamica n. sp. – a new species from Mesopotamia, Iraq (Mollusca: Gastropoda: Assimineidae)

    PETER GLÖER, MURTADA D. NASER, AMA‘AL G. YASSER

    Mollusca. 01/2007; 25(1).

    During malacological investigations of the fauna of Mesopotamia we found an unknown Assiminea species which we describe here as Assiminea mesopotamica n. sp. To fi nd out if this is a new species in fact, we studied especially the outstanding papers of ABBOTT (1958) and BRANDT (1974). Both authors m... [more] During malacological investigations of the fauna of Mesopotamia we found an unknown Assiminea species which we describe here as Assiminea mesopotamica n. sp. To fi nd out if this is a new species in fact, we studied especially the outstanding papers of ABBOTT (1958) and BRANDT (1974). Both authors mentioned the anatomy and depicted the species by photographs which allowed us to compare our Assiminea species with the already known species. Most of the Assiminea species are restricted in their distribution to small regions. Though they live in coastal regions they should have a chance of passive dispersal, so most Assiminea species seem to be stenoecious.

[more] Forty-two specimens of Macrobrachium nipponense (de Haan, 1849) were collected from Abu-Zirig Marsh in the south of Iraq, in July 2005. DNA sequences confirmed the morphological identification by 99 % similarity to published 16S sequences. The introduction vector for this non-native species into the wild is considered to be unintentional escapes from Iranian aquaculture. Yes Yes
