Three sampling stations were chosen along the lower reach section of AlSanawbarriver (Lattakia-Syria). In these stations, the freshwater molluscs were studied, environmentally and taxonomically, during the period 4/3/2012 – 4/8/2013. In this research, I present the results of the environmental study on the Gastropod Valvatasaulcyiwhich was more abundant in the 3rd station; 5km of the estuary. Ten mollusc species were identified; 8 belonging to Gastropoda (4 of Prosobranchia & 4 of Pulmonata) and 2 belonging to Bivalvia. The chemical and physical properties of the water in the 3rd station were studied and the work was concentrated on Valvatasaulcyipopulation and structure, where samples were collected bimonthly during Spring, summer & autumn and monthly during winter. It was shown that reproduction of such species is continuous along the year, with 2 reproduction beaks: the more important one is spring beak and the less important one is autumn beak. The population structure of the species was studied: shell dimensions were measured and the relationships were studied between height growth and breadth growth of the shell, and between the breadth growth and dry weight of the individual ….

Research summary
تتناول هذه الدراسة البيئية الرخويات بطنيات القدم Valvatasaulcyi في إحدى محطات المجرى السفلي لنهر الصنوير في محافظة اللاذقية بسوريا. تم اختيار ثلاث محطات على طول المجرى السفلي للنهر، وأجريت الدراسات البيئية والتصنيفية على الرخويات المائية العذبة التي تقطنها خلال الفترة من 4 مارس 2012 حتى 4 أغسطس 2013. تم تحديد عشرة أنواع من الرخويات، ثمانية منها تنتمي إلى صف بطنيات القدم وأربعة أنواع من تحت صف أماميات الغلاصم وأربعة أنواع من تحت صف الرئويات، ونوعان ينتميان إلى صف ثنائيات المصراع. ركزت الدراسة على جماعة الرخوي Valvatasaulcyi وبنيتها، حيث جمعت العينات بمعدل مرة كل 15 يوماً خلال فصول الربيع والصيف والخريف، ومرة واحدة شهرياً خلال فصل الشتاء. أظهرت النتائج أن التكاثر مستمر عند أفراد هذا النوع على مدار العام، مع وجود ذروتين للتكاثر: الأولى ربيعية مهمة، والثانية خريفية أقل أهمية. كما تم دراسة بنية الجماعة، حيث حددت أبعاد القواقع، والعلاقة بين النمو في الارتفاع والنمو العرضي للقوقعة، والعلاقة بين النمو في الارتفاع والوزن الجاف للحيوان بالكامل.
Critical review
دراسة نقدية: تعتبر هذه الدراسة ذات أهمية كبيرة في مجال البيئة والتصنيف الحيوي للرخويات المائية العذبة، حيث تقدم معلومات جديدة ومهمة عن توزيع وتكاثر الرخويات بطنيات القدم في نهر الصنوير. ومع ذلك، يمكن الإشارة إلى بعض النقاط التي قد تحتاج إلى تحسين. أولاً، كان من الممكن توسيع نطاق الدراسة ليشمل محطات إضافية على طول النهر للحصول على صورة أكثر شمولية. ثانياً، يمكن أن تكون هناك حاجة إلى مزيد من التحليل الكيميائي والفيزيائي للمياه لفهم تأثير العوامل البيئية على تكاثر ونمو الرخويات بشكل أفضل. وأخيراً، قد يكون من المفيد إجراء دراسات مماثلة على أنواع أخرى من الرخويات في نفس المنطقة لمقارنة النتائج وتقديم توصيات أكثر شمولية.

    غطت الدراسة الفترة من 4 مارس 2012 حتى 4 أغسطس 2013.

  2. كم عدد أنواع الرخويات التي تم تحديدها في الدراسة؟

    تم تحديد عشرة أنواع من الرخويات في الدراسة.

  3. ما هي ذروتا التكاثر عند الرخوي Valvatasaulcyi؟

    الذروة الأولى للتكاثر هي في الربيع وتعتبر مهمة، والذروة الثانية في الخريف وتعتبر أقل أهمية.

  4. ما هي العلاقة بين النمو في الارتفاع والنمو العرضي للقوقعة؟

    هناك علاقة خطية طردية بين النمو في الارتفاع والنمو العرضي للقوقعة، حيث كان النمو في الارتفاع أبطأ من النمو العرضي.

Six water stations were chosen along the lower reach section of AlKebir ALShimaly river and some of it's tributaries, differing in their biotic and abiotic features. Water and animal samples were collected bimonthly during spring, summer & autumn a nd monthly during winter during the period 25/8/2013 – 26/8/2014. Seventeen species of freshwater molluscs were identified in all stations, fifteen belonging to Gastropoda (6 of Prosobranchia & 9 of Pulmonata) and 2 belonging to Bivalvia, one of it (Corbicula fluminea) was recorded for the first time in Syrian Arab Republic. We focused on in this study on the station ( Mafraq Quesmeen) that we studied it's chemical and physical properties of the water and we identified 11 mollusc species and the most frequency of it was Melanopsis praemorsa and it's frequency rate was 46.48% and it was the most constant in all continuous samples and it was 100%
This research is a study of distribution of Patella caerulea in four locations of the Latakia shore different from each other by Substrate nature and their exposure to pollution sources. They are as follow : Afamia (A),Ibn Hani (B) ,harbor fishing of Tower Islam (C), and the sandy beach of Tower Islam (D). This study was achieved between January 2012 and January 2013 ,The samples were collected manually from the Supralittoral , Littoral and Sublittoral region(depth of two meters).The results of this study showed the following: 1 – The area A is the most suitable for the growth and reproduction of the Patella caerulea, which recorded the highest value of biomass reaching ( 3990.2 gr / m²), and the number of individuals (2128 ind /m²) . 2 - The area C recorded the lowest value of biomass (2872.47 gr/ m²) and the number of individuals (1632 ind / m²). 3 - Patella caerulea is consederied a Eurybiont as it was found in all the study areas . 4 - Patella caerulea is comercially important species .
Soccer game is one of the more games that players are exposed to sports injuries and the reason for this is due to the large increase of the practitioners of this game as well as the characteristics of this game that are frequently the friction betwe en the players.

Rural centers in Lattakia Governorate can receive groups of tourists in villages and provide them with residence. As a result of development and progress started in the 1980s, the Syrian rural areas have undergone principal structural changes. In thi s Governorate, the rural centers are characterized by a good level of service in addition to natural and economic features as well as a rural person with a strong sense of self trust and developed intellectually, socially and medically. This is to be reflected in the reduction of unemployment as well as in the decline of migration from villages to cities. Therefore, it is useful to affiliate the social and economic development of the rural communities with the rural tourist industry in order to create economic and demographic stability and provide an additional source of income.
