Morphological Variations of the Shell of the Bivalve Lucina Pectinata
I S S N 2 3 47-6 8 9 3 Volume 10 Number2 Journal of Advances in Biology Morphological variations of the shell of the bivalve Lucina pectinata (Gmelin, 1791) Emma MODESTIN PhD of Biogeography, zoology and Ecology University of the French Antilles, UMR AREA DEV ABSTRACT In Martinique, the species Lucina pectinata (Gmelin, 1791) is called "mud clam, white clam or mangrove clam" by bivalve fishermen depending on the harvesting environment. Indeed, the individuals collected have differences as regards the shape and colour of the shell. The hypothesis is that the shape of the shell of L. pectinata (P. pectinatus) shows significant variations from one population to another. This paper intends to verify this hypothesis by means of a simple morphometric study. The comparison of the shape of the shell of individuals from different populations was done based on samples taken at four different sites. The standard measurements (length (L), width or thickness (E - épaisseur) and height (H)) were taken and the morphometric indices (L/H; L/E; E/H) were established. These indices of shape differ significantly among the various populations. This intraspecific polymorphism of the shape of the shell of P. pectinatus could be related to the nature of the sediment (granulometry, density, hardness) and/or the predation. The shells are significantly more elongated in a loose muddy sediment than in a hard muddy sediment or one rich in clay. They are significantly more convex in brackish environments and this is probably due to the presence of more specialised predators or of more muddy sediments. Keywords Lucina pectinata, bivalve, polymorphism of shape of shell, ecology, mangrove swamp, French Antilles. -

Ise-Shima National Park Lies on the Shima Peninsula, Located in the Center of Mie Prefecture in Western Japan
A scared landscape featuring the historical site of Ise Jingu Grand Shrine, as well as a picturesque coastal route and bountiful seascape 12 Ise-Shima Ise-Shima National Park lies on the Shima Peninsula, located in the center of Mie prefecture in Western Japan. Ise-Shima National Park includes the municipalities of Ise, Toba, Shima, and Minami-Ise, occupying a vast area of National Park nearly 60,000 hectares. The park is broadly divided into two areas: the inland area which is home to Ise Jingu and its surrounding forests; and the coastal area which is characterized by an archipelagic landscape with intricate ria coasts. The interaction between people and nature is very profound in the region, and the essence of this relationship can be observed in the ancient tradition of ama, female diver, fishing, among other traditional cultural practices that have developed around Ise Jingu over the millennia. The wisdom to enjoy the bounties of nature in a sustainable manner is figured prominently in Ise Jinguʼs Shikinen Sengu, a ritual held once every 20 years whereby the shrine is rebuilt in its entirety. The region has a long history of providing seafood to the Imperial Court and Ise Jingu, and the Manyoshu (Japanʼs oldest poetry compilation) refers to the region as Miketsu Kuni or the "land of divine off erings". Thus, the region boasts a rich marine environment home to diverse aquatic life, including Japanese spiny lobster, abalones, turban shells, oysters, tunas, red sea breams, and various types of seaweed. The Kuroshio sea current has blessed the region with a warm climate, which has led to the development of Ise Jinguʼs lush forest and dense evergreen forests that cling to the foothills of the mountainous regions. -

As reported in Gem-A News and Views (page Spring 40), we have a lease renewal on our Greville Street premises which will lead to a thorough refurbishment — something which those of you who know the building will agree is much needed. This will provide an excellent opportunity to reinvigorate both our onsite teaching facilities and the services we can offer members. How can we afford this you may ask, when only a very few years 12 ago the Association was in poor health financially? The fact is that over the last few years we have run a very tight ship knowing we had these costs looming. We have focused on what we are good Contents at and the things which are the core aspects of our business. This has led to the ceasing of loss- making operations, such as the laboratory, and an increase in students and thus revenue from our education, though it must be qualified that this increase is from overseas rather than the UK. -

E-mail: [email protected] Abstract: The pearl oyster Pinctada radiata (Leach, 1814) is an alien species introduced to the Mediterranean Sea and recorded in Tunisia many years ago. However, since its record in Tunisian inshore areas, no studies have been carried out about the spread of this invasive mollusc. Thus, the status of this species is still poorly known and there is a knowledge- gap about its distribution and ecology. -

1965 Around the World Random Scientific Notes from a World Tour
1965 AROUND THE WORLD RANDOM SCIENTIFIC NOTES FROM A WORLD TOUR Dad had died in November 1964 and Mother wanted to go to Japan and visit friends the following year. Not wanting to go alone, she invited me. I didn’t keep a diary on this trip but wrote my husband every night. From these letters I have compiled the following. October 8, 1965. Royal Hawaiian Hotel, Waikiki. Well it just wasn’t my day. Starting with the carpool in Baby (my Sunbeam Alpine sport car) the omens were all against it.1 Lunch from Cincinnati to Chicago was served in 45 minutes and was merely a shrimp cocktail, steak, potatoes, vegetable, salad, coffee, desert and champagne. We got to Chicago at 1:53, which meant that if the San Francisco plane had been on time, I would have missed it, but it didn’t leave until 1:54. By breaking the one-minute mile record, I was out of breath as I hurried aboard. I found Mother had not gotten our message and was sick as a dog with intestinal flu. Lunch from Chicago to San Francisco was more leisurely with cocktails, a three-course meal, three wines etc. All I saw of San Francisco was the Aloha Lounge and every cafeteria in the place trying to find Mother some dry toast. It was too foggy to see the Golden Gate Bridge even if I had known where to look. The flight to Hawaii was four and a half hours and we had a leisurely dinner that was served on tablecloths by Muumuu-clad stewardesses.
