ANOMURA OF THE ISKENDERUN BAY REGION (SOUTHEASTERN TURKEY) BY CENGIZ KOÇAK1), TUNCER KATAGAN and TAHIR OZCAN Department of Hydrobiology, Faculty of Fisheries, Ege University, TR-35100 Bornova-Izmir,˙ Turkey INTRODUCTION The present study was conducted to investigate the Anomura of the coasts of Iskenderun Bay. The study area is located in the northeast of the Levantine Basin, and is 65 km in length and 35 km in width, covering an area of approximately 2275 km2. The bay has an average depth of 70 m (Iyiduvar, 1986). There is a euphotic water column and the amount of nutritional substances is 2-4 times higher than in truly offshore areas nearby. There is neither thermal stratification nor significant eutrophication, because of the dynamic structure of the bay (Yılmaz et al., 1992). Since it has a large area of contact with the open sea, it is not affected by either the wind or by deep currents. The bay has a rocky bottom at the southeast and northeast, and there is much seaweed in the northeastern area, while the rest comprises sandy-muddy bottoms. Studies on the anomuran fauna of Iskenderun Bay are few. The first record is by Monod (1931), who reported one species (Galathea nexa Embleton, 1834). Next, Katagan & Cevik (2003), likewise reported one species of Anomura, i.e., Albunea carabus (L., 1758). Until now, only these two Anomura were known from Iskenderun Bay. MATERIALS AND METHODS Specimens of Anomura were collected at six sampling stations: Sta. 1, Karatas; Sta. 2, Yumurtalık; Sta. 3, Dortyol; Sta. 4, Iskenderun; Sta. 5, Arsuz; Sta. 6, Samandagı (fig. 1) from July 2002 to June 2003. A total of 72 surveys were conducted. Samplings were made by trawling and nets on board the R/V “Mustafa 1) Author for correspondence; e-mail: kocak@sufak.ege.edu.tr © Koninklijke Brill NV, Leiden, 2005 Crustaceana 78 (2): 247-252 Also available online: www.brill.nl 248 NOTES AND NEWS Fig. 1. Sampling stations in and around Iskenderun Bay, Turkey. Kemal-I”, at depths ranging from 4 to 50 m. The trawl was equipped with an 18 mm mesh size net at the cod-end. A haul lasted about one hour, at a towing speed of 1.5 knots (c. 2.7 km.h−1). Specimens were fixed immediately with formaldehyde 5% and later rinsed with fresh water and preserved in 70% ethyl alcohol. The nomenclature of the species follows ERMS (2004). RESULTS Anomura were captured at two stations of different depths (22-50 m) out of the six stations sampled. In all, 29 specimens belonging to 3 families and 4 species were identified. The family Diogenidae was represented by 2 species, the Paguridae by 1 species, and the Albuneidae by 1 species (see below). Three of these species (Dardanus calidus (Risso, 1827), Paguristes eremita (Linnaeus,.

Taxonomic Study of the Pagurus Forbesii "Complex" (Crustacea
Taxonomic study of the Pagurus forbesii "complex" (Crustacea: Decapoda: Paguridae). Description of Pagurus pseudosculptimanus sp. nov. from Alborán Sea (Southern Spain, Western Mediterranean Sea). GARCÍA MUÑOZ J.E.1, CUESTA J.A.2 & GARCÍA RASO J.E.1* 1 Dept. Biología Animal, Fac. Ciencias, Univ. Málaga, Campus de Teatinos s/n, 29071 Málaga, Spain. 2 Inst. Ciencias Marinas de Andalucía (CSIC), Av. República Saharaui, 2, 11519 Puerto Real, Cádiz, Spain. * Corresponding author - e-mail address: garciaraso@uma.es ABSTRACT The study of hermit crabs from Alboran Sea has allowed recognition of two different morphological forms under what had been understood as Pagurus forbesii. Based on morphological observations with various species of Pagurus, and molecular studies, a new species is defined and described as P. pseudosculptimanus. An overview on species of Pagurus from the eastern Atlantic and Mediterranean Sea is provided. Key words: Pagurus, new species, Mediterranean, eastern Atlantic. 1 Introduction More than 170 species from around the world are currently assigned to the genus Pagurus Fabricius, 1775 (Lemaitre and Cruz Castaño 2004; Mantelatto et al. 2009; McLaughlin 2003, McLaughlin et al. 2010). This genus is complex because of there is high morphological variability and similarity among some species, and has been divided in groups (e.g. Lemaitre and Cruz Castaño 2004 for eastern Pacific species; Ingle, 1985, for European species) with difficulty (Ayón-Parente and Hendrickx 2012). This difficulty has lead to taxonomic problems, although molecular techniques have been recently used to elucidate some species (Mantelatto et al. 2009; Da Silva et al. 2011). Thirteen species are present in eastern Atlantic (European and the adjacent African waters) (Ingle 1993; Udekem d'Acoz 1999; Froglia, 2010, MarBEL Data System - Türkay 2012, García Raso et al., in press) but only nine of these (the first ones mentioned below) have been cited in the Mediterranean Sea, all of them are present in the study area (Alboran Sea, southern Spain).

The spermatophores show similarities with those described for other members of the family Diogenidae (especially the genus Cliba narius), and are composed of three major regions: a sperm-filled, circular flat ampulla; a columnar stalk; and a pedestal. The morphology and size of the spermatophore of L. loxochelis, along with a distinguishable constriction or neck that penetrates almost halfway into the base of the ampulla, are characteristic of this species. The size of the spermatophore is related to hermit crab size. Direct relationships were found between the spermatophore ampulla width, total length, and peduncle length with carapace length of the hermit crab. These morphological characteristics and size of the spermatophore ofL.

A. Pastore Istituto Sperimentale Talassografico Taranto, via Roma 3, 74100 Taranto, Italy Two sources give information about Jonian Decapoda. One, by Costa1 is a catalogue of 51 Decapoda found in the Taranto area. Also in Costa2, two other species are mentioned which make a total number of 53. The other source, by Forest', is a list of 67 Decapoda found in the Porto Cesareo area. The list of the species is enlarged by a new find in the Gulf of Taranto and the Gulf of Catania. Dromidiopsis spinirostris (Miers, 1881) is also a new Record for the Mediterranean Sea. At the moment, 119 species of Decapoda in the Jonian Sea are re corded, 25 of which are not recorded above. In this work we have examined 74 species: 6 Peneidaea, 8 Caridea, 7 Macrura reptantia, 11 Anomura and 42 Brachiura. INTRODUCTION The materials studied in this work were collected under various circum stances and at different times and places from 1969 until today. All of them are from the Jonian sea. Most of these species are common or very common in the western Medi terranean. But there are some species which are mentioned here for the first time. There is very little literature for the Jonian sea. We have found only five works which deal with the area. From the past century Rizza4 describes material from the Gulf of Catania and Costa1 describes material from the Gulf of Taranto.

Standardization in air acoustics began as an initiative of the American Standards Association (now ANSI) in the 1930s, and the International Organization for Standardization (ISO) established its technical committee Acoustics (TC 43) in 1947. Seventy years later we can buy a standardized sound level meter knowing that it applies an appropriate auditory filter, tuned to the perception of human hearing. In underwater acoustics the process of international standardization is in its infancy. For example, as of 2019 there exists no standard hearing filter for a single species of aquatic animal, no international standard for measuring sound pressure or particle motion, or hearing thresholds, source levels or scattering strengths of aquatic biota. ISO TC 43’s first step towards standardization in underwater acoustics was made in 2011 when it established the sub-committee Underwater Acoustics (TC 43/SC 3).

M.] The examination of certain decapod crustacean collections from the Aegean Sea and the review of the relevant literature showed that the number of the species known from this area is 231. Seven of these species are reported for the first time from the eastern Mediterranean and three from the Aegean Sea. For the 19 more interesting species found, information on their distribution and their habitat is given. The numbers of decapods known from the entire Mediterranean, the Adriatic Sea, the coast of Israel and the Black Sea, according to the existing literature, are estimated. The affinities among the decapod faunas of the above areas are estimated by the coefficient of CHEKANOWSKI together with the number of species common to each pair of areas. The most strongly related fauna to that of the Aegean Sea is the fauna of the Adriatic. The fauna of the coast of Israel is more related to that of the coast of Cyprus although their degree of affinity is lower than that between Adriatic and Aegean. The two pairs of areas have an affinity with each other of about 60 %.
