Although leptocephali are very conspicuous in plankton samples little is known about their occurrence and distribution along the Brazilian coast. Therefore, the present study aimed to identify the leptocephali and their distribution pattern along the eastern Brazilian coast, which is limited in the north by Real River (12°S) and in the south by São Tomé Cape (23°S). Samples were collected during three oceanographic cruises conducted on October–December 1998, May–July 1999 and March–May 2000. Samplings were done using a bongo net with mesh apertures of 330 and 500 µm. The net was towed obliquely and the maximum depth was 200 m. A total of 13 families, 12 genera and 29 species of leptocephali were identified in the study area. Most taxa identified had already been recorded as adult, but the larval phase of some of them had not been identified for this region yet. Among them, Derichthyidae, Avocettina paucipora and Tiluropsis had not been recorded for this region either as adult or as larvae. Most taxa occurred mainly along the Bahia coast but some species were collected strictly in the southern region of the study area.

Single Genus

Fistulariidae contains the single genus, Fistularia, with four species. Two of these species are recorded from Brazil: Fistularia petimba and F. tabacaria. This study describes larvae of these two species of Fistularia, recording their distribution along the southeastern Brazilian coast, which is limited in the north by Real River (12° S) and in the south by São Tomé Cape (22° S). Samples were collected using a bongo net with mesh apertures of 330 and 500 µm during three oceanographic cruises conducted on spring/98 (Central III), winter/99 (Bahia 1) and autumn/00 (Central IV). The net was towed obliquely and the maximum depth was 200 m. Larvae of F. petimba were the most abundant and most widely distributed within the study area, including the seamounts of the Vitória-Trindade Ridge. Larvae of F. tabacaria were recorded only between 14° S and 21° S.

AbstractThe Order Suberitida is defined as a group of marine sponges without an obvious cortex, a skeleton devoid of microscleres, and with a deletion of a small loop of 15 base pairs in the secondary structure of the 28S rDNA as a molecular synapomorphy. Suberitida comprises three families and 26 genera distributed worldwide, but mostly in temperate and polar waters. Twenty species were reported along the entire Brazilian coast, and although the north-eastern coast of Brazil seems to harbour a rich sponge fauna, our current knowledge is concentrated along the south-eastern Atlantic coast. A survey was implemented along the northern coast of Brazil, and the collection allowed the identification of six species belonging to the Order Suberitida. Two of them are considered new to science: Suberites purpura sp. nov., Hymeniacidon upaonassu sp. nov., and four, Halichondria (Halichondria) marianae Santos, Nascimento & Pinheiro, 2018, Halichondria (H.) melanadocia de Laubenfels, 1936, Suberites aurantiacus (Duchassaing & Michelotti, 1864), and Terpios fugax Duchassaing & Michelotti, 1864, are re-described. Taxonomic comparisons are made for Tropical Western Atlantic species and type species of the four genera. Finally, an identification key for the Western Atlantic Suberites species is provided.

P Element Regulation

Clines of P-induced hybrid dysgenesis provide a means for monitoring the evolution of transposition repression over space and time. We have studied the molecular and phenotypic profiles of flies taken from a 2900 km cline along the eastern coast of Australia, which had previously been characterized over 10 years ago as having P populations in the north, Q populations at central sites and M′ populations in the south. We have found that Q and M′ populations of flies have increased their range within the cline at the expense of P lines. Q populations were found to be in the north of the cline and M′ populations in the south. Some of the northern Q lines transmit repression through both sexes and type I deletion elements have been isolated from them. We suggest that these elements are responsible for Q type repression. The results support our model that populations made up of Q individuals with strong biparentally transmitted repression form an evolutionarily stable strategy for the repression of hybrid dysgenesis in Drosophila melanogaster.

This chapter deals with the Intifada, the great popular uprising against the regime that broke out in Iraq in March 1991 in the Shiite territories in the south and spread to Kurdistan in the north. The Sunni areas in the center of the country remained quiet throughout the period. It describes its causes and the rebels success in occupying a number of cities in the southern region and in Kurdistan, constituted a serious threat to the regime that responded immediately. It describes the regime cruel suppression of the rebels and the supporting civilian population by his loyal forces, the Republican Guard and the Special Republican Guard, involving much bloodshed, but succeeding in totally quelling the uprising.

In the article “Tides” in the Encyclopœdia Britannica, Professor George Darwin, quoting Sir George B. Airy, remarks that the tides of the North Sea present a very remarkable peculiarity. Along the eastern coast of England as far as the mouth of the Thames, the tide-wave, coming from the Atlantic round the Orkney Islands, flows towards the south. Thus, on a certain day, it is high water in the Moray Firth at 11 a.m., at Berwick at 2 p.m., at Flamborough Head at 5 p.m., and so on to the entrance to the Thames. Thus, on the day supposed, it will be high water off the Thames at 11 p.m., the tide having travelled in twelve hours from the Moray Firth.It is further stated that the North Sea is considerably deeper on the English side than on the German side; so much so, that the tide-wave coming from the north runs into a deep bay of deep water, bounded on the west side by the Scottish and English coasts as far as Newcastle, and on the east side by the great Dogger Bank. As far as the latitude of Hull, the English side is still the deep one; and though a species of channel through the shoal there allows an opening to the east, yet immediately on the south of it is the Wells Bank, which again contracts the deep channel to the English side.It is not stated here that the deeper water of the North Sea close to the Scottish and English coasts determines the course of the southward tidal flow to be close to these coasts; but for that course taken, no other cause is suggested.

AbstractA total of 299 fish belonging to ten teleost species were studied in Iranian waters at the north-eastern coast of the Persian Gulf for larval trypanorhynch cestode infection. The following trypanorhynch species were identified: Callitetrarhynchus gracilis Pintner, 1931, Pseudogilquinia thomasi (Palm, 2000), Pterobothrium lesteri Campbell and Beveridge, 1996 and Pseudolacistorhynchus shipleyi (Southwell, 1929). The most abundant parasite was C. gracilis which was isolated from seven teleost species. The highest prevalence (62.9%) and dominance (0.98) were demonstrated for P. thomasi with a maximum intensity of 22 in Indian halibut Psettodes erumei. Collections of P. lesteri and P. shipleyi from the Persian Gulf represent new locality records, thus extending the known range of distribution for both species. Four new host records are established. The recorded combination of trypanorhynch species and the established host range correspond to other regions, such as off the Brazilian coast. In terms of species distribution, the north-western part of the Indian Ocean, together with the Gulf of Bengal and the Indonesian archipelago, share the same species, resulting from connected water bodies. All trypanorhynch species were isolated from the body cavity, except for P. thomasi which was recorded from the musculature of P. erumei. Relatively high intensities of infection in P. erumei may be of public health concern in the region, necessitating the consumption of well-cooked fish products.
