This study was conducted during the period from 10/9/2016 to 9/9/2017 in Demsarkho
orchards area (Lattakia) on the west coast of Syrian Arab Republic. The study aimed to
identificate "Syrphidae" in this area. Samples were collected by yellow dishes
in weekly
rate. A total of 341 Syrphid flies were collected and they belong to 15 species form 10
genera. The most abundant species was Sphaerophoria scripta (relative abundance
33.43%), followed by Episyrphus balteatus (20.53%), then Melanostoma mellinum
(14.66%).

Vertical sampling process took place to Copepoda during the summer and winter of
2009 and 2010 from Alzzouzo castle which is located in the coastal region of Jableh city.
This region has special environmental properties. Sampling was accompanied wi
th
measuring water temperature, salinity, and dissolved oxygen in the water.
The total number of samples studied in all areas of study is 106 samples. 100 species
were identified during the summer, while 89 species were identified during the winter;
most species belongs to the order of Calanoida. It was noted by the study that most species
appeared in two seasons together, while some species appeared in the season without the
other. It was also noted that the abundance of Copepoda was higher in summer with an
average of (5314 individual / m
3), while the average in winter was (4353, 40 individual / m
3).
It was clear from the study that the station near the beach was less diverse and more
prolific than the offshore station during the summer and winter together.
Zooplankton samples were collected seasonally from three stations in the south of
Al-Hammar Marshes southern Iraq during the period from January to December 2011, by
Plankton net of a mouth aperture of 40 cm and a mesh-size 0.90 mm mounted with a f
low
meter in the mouth. The results showed that the population density of Cladocera ranged
between 79 ind/m3 during winter at station 1 (Al-Mas-hab) and 41971 ind/m3 during spring
at station 2 (Hareer). Density of Cladocera was positively correlated with water
temperature and to a lesser extent with salinity. About 13 species of Cladocera belonging
to 11 genera were recorded at three stations. The high values of diversity were recorded in
winter at all stations (1.68, 1.16, and 1.68 respectively) while the lowest values were
recorded during spring at all stations (0.06, 0.03, and 0.01 respectively).
