Coralline red algae are highly abunadant and well diversified in the well exposed carbonate deposits of the Lower Pliocene Shagra Formation at Wadi Wizer, Red Sea coast, Egypt. Lithostratigraphically, the Shagra Formation unconformably overlies the Late Miocene Marsa Alam Formation and underlies the Quaternary deposits. This carbonate facies is dominated by different assemblage of coralline red...

Detection of red tides (harmful algal blooms or HABs) from space has been problematic in optically complex waters, mainly due to interference from non-pigment constituents to the satellite signal. Using in situ and MERIS (Medium Resolution Imaging Spectrometer) measurements, the spectral characteristics of red tide and non-red tide waters were studied in the East China Sea coastal area. Two sur...

osteological features are important to study the taxonomy and phylogenetic relationship of fishes. since there is no information is available about osteological features of squalius orientalis , therefore this study was aimed to provide a detailed description of the osteological features of this species from the urmia lake basin of iran and comparing it with population of s. orientalis from the...

The ability to recognize individuals and track growth over time is crucial to population dynamics research as well as studies of animal behavior. Invertebrates are particularly difficult to track as they often molt, have regenerative capabilities, or lack hard parts to attach markers. We tested, in laboratory and field studies, a new way of marking sea anemones (order Actiniaria) by injection o...

Irradiated red ginseng powder (2.4 kg) in commercial bottles was transported from Korea to Iowa State University (USA) via air(10 days) and sea-cargos (50 days) to prove its qualities and identity. The microbial loads of transported samples by both methods after 5 kGy irradiation were reduced from 10 to 10CFU/g in total aerobic bacteria and from 20CFU/g (minimum detection level) to negative in ...

The spatial distribution of 50 ornamental fish species from shallow water habitats on coral reefs were investigated using visual census techniques, between latitudes 11-29°N in the Red Sea, in Jordan, Egypt, Saudi Arabia, and Yemen, and in the adjacent Gulf of Aden in Djibouti. One hundred eighteen transects (each 100×5 m) were examined in 29 sites (3-8 sites per country). A total of 522,523 fi...
