This paper summarizes the results of a study, which was conducted during the period of 1996-2005. It assesses the impact of river diversion (Third River), marsh drainage, and marsh restoration on Kuwait's marine environment. The results indicated lower salinity, higher nitrate concentration, higher chlorophyll-a, and higher sedimentation in the northern waters of Kuwait influenced by the discharge of the man-made Third River and marsh drainage. Five estuarine copepod species, which occur only in the northern waters of Kuwait due to their proximity to the mouth of the river, are reported here for the first time. Lower turbidity levels were observed in the northern waters of Kuwait during 2004 and 2005 possibly influenced by the marsh restoration process. The above results indicate the close interrelationship between the upstream river environment and the northern Arabian Gulf. River-related activities in the Tigris-Euphrates Basin have transboundary impacts downstream. Assumptions on the potential effects of the upstream damming of the Tigris and Euphrates Rivers on Kuwait's marine environment are included. It is expected that recent and planned river basin modifications in Turkey, Iran and Iraq will significantly reduce river discharge, permanently remove seasonal flooding, and impact the northern Gulf's marine environment, with serious implications for fisheries.
An attempt was made to analyze and classify water quality at the Bukit Merah Reservoir (BMR) in Malaysia to determine the degree of pollution and ascertain the required treatment level before usage. Parameters determined included; pH, dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), ammoniacal nitrogen (NH3-N), suspended solids (SS), total nitrogen (TN) and total phosphorus (TP) using both in-situ and standard laboratory procedures. Heavy metal contents such as nickel (Ni), cadmium (Cd), copper (Cu), zinc (Zn), lead (Pb), calcium (Ca), iron (Fe) and magnesium (Mg) were also determined using an Inductively Coupled Plasma Mass Spectrometer (ICP MS). Using the water quality index (WQI) tool, all the parameters indicated considerable degrees of pollution with an average classification number of 75.63 in Class III which indicated that the BMR water was slightly polluted. DO ranged between 2.06 and 12.5 mg/L with a mean value of 5.96 mg/L while BOD ranged between 3.08 and 6.32 mg/L with a mean value of 4.6 mg/L, among many other parameters analyzed. Also, the presence of heavy metals was recorded, but did not appear to be much of a threat with the exception of Fe. Most of the pollutants identified were mainly from infrastructural development and agricultural activities. For domestic uses, cleaner water would be required and this would need substantial investment in treatment, while for recreational, livestock and crop irrigation purposes, the water quality would be acceptable at the present level.
Abstract-This study is to determine the concentrations of sixteen poly aromatic hydrocarbons in eighteen pooled samples of fish, shrimp, crab and bivalve from markets of Hormozgan province, Iran. The poly aromatic hydrocarbon levels varied from 16 ± 8.4 to 28.18 ± 3.74 ng/g wet weight. The investigated samples were classified as minimally contaminated. Distribution patterns showed that PAHs with 4, 5 and 6 rings dominated, confirming the pyrogenic source of detected PAHs. Fish contributed more than other biota groups in transforming of PAHs to Hormozgan Province people. The average of B (a) P eq) values for the studied biota was 2.71 ± 2.28 ng/g that was greater than calculated local screen value. This finding was implemented in poor quality of studied biota and necessity for risk management.Index Terms-Hormozgan Province, PAH, risk assessment, seafood.
The Bukit Merah Orang Utan Island (OUI) Foundation has been conducting behavioral and veterinary research on orangutans as an attempt at ex situ conservation. Since 2010, the Primate Research Institute, Kyoto University has been collaborating with OUI to promote environmental enrichment and infant rearing by biological mothers in addition to the continuous efforts of refining the veterinary management of the endangered species. In 2011, three Bornean orangutans (Pongo pyg-maeus pygmaeus) were released on an island, called BJ Island, adjacent to OUI. This island is approximately 5.6 ha in size, and 635 trees belonging to 102 plant species were identified prior to their release. Behavioral monitoring of the released individuals has been conducted to evaluate their behavioral adaptation to the new environment. Two of the three released orangutans were born in the wild, whereas the youngest individual was born on OUI and expected to learn forest survival strategies from the two older individuals. One of the orangutans was pregnant at the time of release and subsequently gave birth to two male infants on BJ Island. The behavioral monitoring indicated that these orangutans traveled more and spent more time on trees following their release onto BJ Island. However, resting was longer for two females both on OUI and BJ Island when compared to other populations. The orangutans consumed some natural food resources on BJ Island. The release into a more naturalistic environment may help the orangutans to develop more naturalistic behavioral patterns that resemble their wild counterparts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
