This study was carried out in nine sites of various altitudes. The sites represent scattered zones of Cordia myxa Forsk. as an introduced species in the coastal region, Lattakia governorate during 2010-2011. The research showed that there is an effect of altitude on the investigated trees in the different sites, and that there were significant differences in relation to the characteristics of the average of the following: tree height, length of leaf stalk, catkin length, canopy, fresh and dry leaf weight, and fruit weight. However, there were no effects of altitude on the species. There were also no observed significant differences in relation to the characteristics of the average of the following: the tree diameter, trunk length, flower number in one catkin, leaf length, leaf width, leaf area, leaf humidity percentage, flowering start, and flowering period. It can be said that there were changes in the morphological characteristics of the studied trees in the different sites, which appeared to be a preliminary indication of the impact of altitude on the variations of some morphological characteristics of Cordia myxa Forsk.

Research summary
تتناول هذه الدراسة الصفات الشكلية لنوع الدبق (Cordia myxa Forsk.) في بعض مناطق محافظة اللاذقية وتأثير الارتفاع عن سطح البحر على هذه الصفات. أجريت الدراسة في عشر مواقع مختلفة الارتفاع خلال عامي 2010-2011. أظهرت النتائج وجود فروق معنوية في بعض الصفات مثل ارتفاع الأشجار، طول عنق الورقة، طول العنقود الزهري، التغطية الشجرية، الوزن الرطب والجاف للأوراق، ووزن الثمار. بينما لم يظهر أي تأثير للارتفاع على صفات أخرى مثل أقطار الأشجار، عدد الأغصان الرئيسية، طول الجذع الرئيسي، عدد الزهيرات في النورة، طول الورقة وعرضها، مساحة سطح الورقة، الرطوبة النسبية للأوراق، وأخيراً بداية الإزهار ومدة الإزهار. تشير النتائج إلى وجود تغيرات طفيفة في الصفات الشكلية للأشجار المدروسة في المواقع المختلفة، مما يعكس تأثير الارتفاع عن سطح البحر على بعض الصفات الشكلية لنوع الدبق.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة في فهم تأثير العوامل البيئية على الصفات الشكلية لنوع الدبق في محافظة اللاذقية. ومع ذلك، يمكن تحسين الدراسة من خلال توسيع نطاق العينة لتشمل مواقع أكثر تنوعاً من حيث الظروف البيئية. كما أن الدراسة ركزت بشكل كبير على الصفات الشكلية دون التطرق بشكل كافٍ إلى الصفات الفيزيولوجية والكيميائية التي قد تكون لها أهمية كبيرة في فهم تكيف هذا النوع مع بيئته الجديدة. بالإضافة إلى ذلك، يمكن أن تكون هناك حاجة لدراسات طويلة الأمد لمراقبة التغيرات الموسمية والسنوية في الصفات المدروسة.

This study was carried out during 2014-2015 in two different nurseries located in University nursery (Lattakia governorate) and Salhab nursery (countryside of Hama governorate). Seeds were taken from two sites of Lattakia governorate (Mashqita– Bsn ada) where Cordia myxa exists as exotic species in some coastal regions and three treatments in addition to control were examined .The results showed that there is an effect of scarification of seeds on investigated treatments and were significant differences in germination percentage in both sites which recorded 55% in university nursery and 35% in Al-Ghab nursery. While there were not contrast between the soaking in boiling and tap water treatments on the seed germination energy in Al-Ghab nursery. Scarification treatment gave higher value of germination energy 25% in Al-Ghab nursery and 21.66% in university nursery , while the same treatment decreased germination velocity compared to other treatments in university nursery which seed needed in average ( 8,01 day) whereas the same treatment increased germination velocity in Al-Ghab nursery which needed (1,54 day). Finally, regarding to cutting ,There is not observe to any positive influence to cuttings which treated in ABA hormone (1g/l) for (10,20,30 m). It could be deduced that there were changes in germination percentage, germination energy and germination velocity in two sites which appeared to be a Preliminary indication of impact of the some dormancy breaking treatments on investigated indications of Cordia myxa Forsk. species .
At this study, two species of genus Equisetum L. have been recorded, that they were: Equisetum telmateia L. and Equisetum ramosissimum Desf. E. ramosissimum Desf. was recorded for the first time in Lattakia. The morphological features were used to separate two species: ( number of the scaly leaves in the node area, shape of the sheath, and number of its teeth, number of the grooves at the stem, length of the strobilus and its color, length of the lateral branches). This study showed that: the spores had three coats, the exosporium rounded by the spore like bars with a wide terminal that called: elaters. Also showed obvious difference in measurements the strobilus and the shapes of sterile and fertile stem.

The aimsof this research were to morphologically characterize 27 local genotypes of tulip,to evaluate the genetic variability between them using 32 morphological traits, and to determine their chromosomal number. The results allowed the distinctio n between the studied genotypes based on the morphological characterization of all vegetative,floral andbulb traits. Results confirmed that the main limiting factor for distribution over the screened regionwas the high above sea level.All genotypes were divided into two main groups, the firstone included genotypes located at 400 - 850 m of altitude, and the second one located between 950 -1450 m. The microscopic analysis results showed that all the studied genotypes were diploid (2n=2x=24 chromosomes). Depending on the results of the morphological characterization and the chromosomal number of local genotypes studied, it can be considered the closest to the specie Tulipaagenensis D.C.
Family Vespidae considered as Widespread globally and belong to the order Hymenoptera called wasps, It contains about 5000 species belong to six subfamilies. Members of this family differ in terms of style of living and life cycle and the type of diet. Colors overlap between the black and yellow or red, yellow or three together. This study examined six species belong to the four genera (Vespa, Vespula, Poistes, Delta) and three sub-families are: Sub.Fam. Vespinae, Sub.Fam. Polistinae, Sub.Fam. Eumeninae, gathered from many different areas of the province of Latakia environment (15 area) from altitudes ranging from sea level to a height of 1000 meters, over a period of time it extends from April through October of 2015.
