Spatial distribution of fifty ornamental fish species on coral reefs in the Red Sea and Gulf of Aden
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...
Kanwar Lake is Asia's largest fresh water ox-bow lake. It lies in Manjhaul sub-division of Begusarai district North Bihar. the only Ramsar site Due to rich biodiversity and socio-economic value deserve its international importance. The situated at 250 55' N latitude 860 10' E longitude. A collection species ornamental fishes was made from Lake. present investigation work highlight tal's fish di...
Nutrient losses from residential lawns and landscapes can negatively impact water quality. Information about nutrient leaching from established residential landscapes containing a mixture of woody ornamental plants and turfgrass is limited. The objective of our study was to determine the effect of vegetation cover (turfgrass vs. woody ornamental) on nutrient leaching from established landscapes...
Brevipalpus mites colonize a great number of fruit and ornamental plants. Mite species belonging to this genus have been associated with many plant viruses. Citrus leprosis (CiLV) is the most economically important virus transmitted by B. phoenicis mites. It has recently been shown that ornamental plant species can be alternative hosts of this virus. The high volume of trade and frequent moveme...

In this experiment, 216 fry of Convict cichlid fish with average weight of 0.26±0.008g to martyr Nasser Fazli barabadi laboratories of Gorgan university of agricultural sciences & natural resources in six groups, include control grou...
The connectivity among marine populations is determined by the dispersal capabilities of adults as well as their eggs and larvae. Dispersal distances and directions have a profound effect on gene flow and genetic differentiation within species. Genetic homogeneity over large areas is a common feature of coral reef fishes and can reflect high dispersal capability resulting in high levels of gene...
