تم دراسة التركيب البيوكيميائي عند بعض أنواع الجنس سيستوزيرا Cystoseira: (الطحالب البحرية السمراء Fucophycaea) Cystoseira elegans, Cystoseira barbata, Cystoseira compressa, Cystoseira caespitosa, Cystoseira barbatula و Cystoseira amentacea. جمعت العينات الطحلبية من موقع ابن هاني شمال اللاذقية, في فصل الربيع لعام 2014. تراوحت النسبة المئوية للسكريات المنحلة من (13- 56.78%) من الوزن الجاف. سجل النوع C.amentacea أعلى نسبة من البروتينات (21.76%), و النوع C.barbata أدنى نسبة (9.51%). ترواحت النسب المئوية لللبيدات من (1.25- 5.55%) من الوزن الجاف. سجلت القيمة العظمى لنسبة الرماد عند النوع C.caespitosa (31.18 %) و أدنى قيمة عند النوع C.amentacea (23.84 %). كانت النسبة المئوية لليود عند الأنواع المدروسة: C.compressa و C.caespitosa (0.68 %) , C.barbata (0.69 %) , C.barbatula (0.7%) , C.amentacea (0.71 %), C.elegans (0.8 %). و كانت النسب المئوية للمانيتول ضمن المجال: (2.91-4%). بينت نتائج تحليل التركيب البيوكيميائي للأنواع المدروسة الاختلاف في نسب القيم, و هذا يؤثر على الأهمية الاقتصادية للأنواع من جهة, بالإضافة إلى التأثير في توفر المادة الغذائية للعواشب الرئيسية و التي بدورها تؤثر على بيئتها و تركيب مجتمعاتها من جهة أخرى.
The biochemical composition of some species of Phaeophyceae (Cystoseira): Cystoseira compressa, Cystoseira barbata, Cystoseira elegans, Cystoseira amentacea, Cystoseira barbatula, Cystoseira caespitosa, have been studied. The algal specimens have been collected from Ibn Hani coast north of lattakia in spring 2014. The soluble sugar varies between (13- 56.78%) weight/dry weight [w/dw]. C.amentacea has the highest content of proteins (21.76%), and C.barbata has the lowest (9.51%). Lipid varied between (1.25- 5.55%) [w/dw]. The highest content of ash was in C.caespitosa (31.18%), and the lowest in C.amentacea (23.84%). Iodine was: C.compressa and C.caespitosa (0.68 %), C.barbata (0.69 %), C.barbatula (0.7%), C.amentacea (0.71%), C.elegans (0.8%). Mannitol was within the range (2.91-4%) [w/dw]. Results of biochemical composition of studied species showed the differences between the percentage of values, and this variety affects on the economical value for the species, also affects on the major herbivorous food, that affects on their environment and their community composition.

This research is a continuation of previous studies on the biodiversity of the algae fuchsias to know with the aim of observing the changes that occur in the marine flora such as the emergence of new species or the disappearance of some of them in addition to studying them in terms of quantitative and biochemical terms and the changes they show according to geographical location.
Due to the lack informations on Biochemical of jellyfish in the Syrian waters, the
aim of this paper is determining the nutritional value and organic content for each of the
species Rhopilemanomadica, Pelagianoctiluca and Aequorea forskalea, and co
mpared the
biochemical composition of the three types , so the comparison showed clear differences in
the content of organic material, the sugar were the most concentrated in the three species
and lipid comes in second class, and then followed by the protein content and organic
carbon.A.forskalea was the most containing sugar and R.nomadica the most lipids content,
and P.noctiluca were the most protein content.R.nomadic was the highest content in
organic carbon, R.nomadica and P.noctiluca were convergent contents of organic
phosphorus, while the least contain of organic nitrogenwas in A.forskalea.
This investigation was carried out at the Laboratory of Biotechnology at
General Commission for Scientific Agricultural Research (GCSAR), during the
season 2010-2011. The aim of this research was to study the genetic diversity
among twenty individ
ual plants of seven species and to determine the degree of
genetic similarity using the technique ISSR (Inter Simple Sequence Repeats)
and 10 primers were used for this purpose. All primers proved their
effectiveness in showing polymorphism between the studied species, primers
gave a total 195 allele with a polymorphic percentage 100%. The number of
bands for each primer varied from a minimum of 12 bands for the primer
(ISSR-4) to a maximum of 27 bands for the primer (ISSR-862) in an average of
19.5 bands for each primer, cluster analysis and Dendrogram showed the
highest degree of genetic similarity between accession A.leucoclada1 and
A.leucoclada2 (0.64), while it was low between species A.leucoclada3 and
A.glauca2 (0.10). Results showed vast genetic diversity among the studied
species.
The study focused in this research to determine the trace of some heavy metal
elements (Copper Cu, Cadmium Cd, Lead Pb) in some types of marine macroalgae
scattered on the shore of the city of Banias during 2014, using atomic absorption
spectrosco
py (technology flame Flame- AAS).
The results indicate that the concentrationsofeach of Copper, Cadmium and Lead
have a link with macroalgae types, sampling sites from direction, and Source of pollution
on the other hand; it was observed that the accumulation of heavy metals in both of
Sargassum vulgare (browen algae) and Enteromorpha linza (green algae) was more than
red algae.
Copper concentration ranged between 1.291 ppm and 11.716 ppm in the studied
species, Reaching the highest value in the Enteromorpha linzaalgae and the lowest in
Sargassum vulgarealgae, the highest value of Lead element was (59.354 ppm) in
Enteromorpha linzaand the lowest value of it was (6.46 ppm) in Ulva fasciata, While the
highest values of the element Cadmium recorded (10.457 ppm) in Enteromorpha linza and
the lowest (0.666 ppm) in Ulva fasciata.
This study dealt with the determination of hydrogen sulfide concentrations in the sediments and water of sewage points on the beach of Lattakia city - the southern Corniche region, which witnesses a clear flow of sewage water and the effect of bacter
ia on the emission of hydrogen sulfide (H2S) of high toxicity to the water medium and from it to the air and seasonal changes. These emissions and the role of hydrological factors such as salinity, acidity and temperature in this process.
