جمعت عينات القشريات لينات الدرقة من عدة أوساط مائية عذبة في حوض العاصي (نهر العاصي ، بحيرة قطينة، السدود التجميعية لمياه الأمطار كالزعفران و السنديانة ، نبع التين ) في الفترة الواقعة ما بين آب 2010 و آب 2011 م . حفظت العينات في الكحول 70%. و بعد الفحص الدقيق لأفراد القشريات تم تصنيف أربعة أنواع : نوعان يتبعان لسرطانات المياه العذبة. و قد تم التمييز بينهما تبعاً للأرجل التناسلية للذكر و هما : Potamon potamios وPotamon setiger من فصيلة Potamidae و تحت نوع واحد من الجمبريات Atyaephyrra dessmarestii orintalis من فصيلة Atyidae و من رتبة طرفيات الأرجل النوع Gammarus lacustris من فصيلة Gammaridae. تم وصف مورفولوجي دقيق لكل نوع ، مع توضيح أهم الصفات التصنيفية المميزة مرفقة بالرسوم التوضيحية و الصور.
The samples of Crustaceans (Malacostraca) were collected in the fresh water, from different regions of Al-Assi valley (the river, Katenah lake, the reservoirs such as Al- Zaafaranh, Al-Sindianh and from Al-teen spring), between August 2010 and August 2011. The samples were preserved in alcohol (70 %). After accurate inspection of the collected samples, there were 4 species classified, two species of freshwater belonging to true crabs were recognized by depending on the masculine organs as following: Potamon potamois and Potamon setiger from the Potamidae family, one species of shrimps Atyaephyrra dessmarestii-orintalis from Atyidae family, and only one species of amphipods which was Grammars lacustris of Gammaridae family. All examined species were described morphologically, explaining the most important classified features that distinguish these species presented with clarifying paintings and with the pictures for these features.

Vulnerability assessment of freshwater resources in the Orontes
basin was estimated in the provinces of Homs, Hama and Idlib to
better understand the current situation of water under the prevailing
conditions and to identify the most prominent fac
tors that influence
water susceptibility to environmental changes. This study helps
decision-makers in evaluating and modify existing policies and
implementing suitable measures to improve water resource
management.
This study aims to define bird species that use artificial lakes in Syrian coast, and
evaluate their population size for management and protection of wildlife. Four different
sites were chosen in Syrian coast, which considered the most important ar
tificial lakes.
Point counts method was used in bird survey in November, December, January, February,
March in 2011. 15 waterbird species were recorded belonging to 9 family and 6 order.
Wading birds were the main component of waterbird (60% of all species) in Syrian
coast. Populations size was 1 to 300 individuals. Diversity of birds and their Populations
were greatest in sites which are rich in food ( especially fish). The results showed a
difference in composition of bird communities in studied sites.
This study was carried out for three years (٣-٥ months every year) during
maximum of aquatic hyphomycetes distribution ( in - Autumn and Winter),
which related with the period of leaves-fall. We studied ٩٠ water samples taken
from Banias River. We
identified ٧٠ species of aquatic hyphomycetes by
investigtion ٨٢٨ spore - isolates taken from water samples. The factors
responsible for the occurrence of different patterns of their distribution have
been determined. Therefore, this work is done for the first time in Syria and
given an important side of ecological and botanical diversity in the waters of
our country.
studied the elimination of lead using natural zeolite by studding the the best
conditions to removal lead in a system with two phase: liquid (contaminated water with
lead)-solid (natural zeolite), correlation of the following factors: time of mixin
g phase,
granular size of solid phase, change of pH values, concentration of the calcium element as
a competitor element for the available sites for occupation on the solid phase, the ratio V/m
represents the size of the aqueous phase to the mass of the solid phase and concentration of
lead element.
On the other hand, the possibility of using natural zeolite as a template for storaging
dangerous materials such as lead, has been studied by changing water quality, pH and
temperature.
The results of this research show that and under the following experimental
conditions: time of mixing=4hour, mix of granular size of solid phase, pH< 8,
concentration of calcium = 20 ppm,V/m=100 and concentration of lead = 1000 ppm , the
rate of lead removal range from 60% to 99%.
On the other hand, the results of this research show that changing water quality has
no impact on the ability of natural zeolite for storaging lead as a hazardous waste, while
pH changes have minor effects on this ability of retention and an effect for the high
temperatures on the template was also observed.
Since the beginning of the twentieth century, researchers have isolated and
dentified spreaded and adapted yeasts to variow environmental conditions and
the types of the mediums in which they graw. The industrial features of the
isolated genera, e
specially those used in the food processing and the stability of
their genetic characteristics were studied. Yeasts in medical and industrial
fields were also improved.
