This was the first study in Yemen, and Gulf of Aden aims to investigate the marine organisms in ballast water and sediments, and gives baseline information defines the zooplankton, phytoplankton and invertebrates, associated fuel tankers. Samples from Ballast water were taken from three ships that arrived at Mukalla Port, the Hadhramout coast from ports of Hamriyah port, U.A.E; ports of Taheri, Iran; and Bosaso Somalia (MT: Gulf Petroleum III, MT: Prime Royal, and M T: Breu) respectively. The marine organisms in samples were presented by three taxonomic groups, phytoplankton, zooplankton and benthos. Fifty-eight taxa were identified within this study; which consisted of 17 phytoplankton, 18 zooplanktons and 23 Benthos. The highest density of phytoplankton was 21 Ind/L, with the occurrence of 17 species found in ballast water, while 22 Ind/50cc of 2 species in sediment samples of the tanker Beru, and fewer densities were in Gulf Petroleum and Prim Royal. The most common phytoplankton observed were Coscinodiscus granii, Coscinodiscus jonesianus and Thalassiosira eccentric. The low Zooplankton density was 13 Ind/L with an occurrence of 18 species found in Prim Royal tanker. Copepods were the most dominant zooplankton among the three tankers. Paracalanus parvus had the highest value of dominance followed by Calanopia parathompsoni, Acrocalanus gracilis and Paracalanus denudatus had the lowest occurrence over three tankers. Seven taxa of Dinoflagellates were identified; two of them Ceratium fusus and polykrikos sp. are known to be harmful species.

Abstract: Studies on biological diversity are essential to generate baseline information in natural protected areas. In the present study, we developed a multi-taxonomic inventory in the Sierra del Abra Tanchipa Biosphere Reserve, located northeast of San Luis Potosí, Mexico. Systematic samplings were performed between January 2017 to May 2018, for the taxonomic groups of flora, amphibians, reptiles, birds, and mammals. A total of 3 730 records of 683 species were obtained, corresponding to 427 species of flora, 10 of amphibians, 20 of reptiles, 192 of birds, and 34 of mammals, from which 47 species are threatened. The results obtained represent the critical biodiversity that can be found in this natural protected area. The information will be useful for decision-making on the management and conservation of biodiversity in the Sierra Madre Oriental’s ecological corridor.

This study investigated the occurrence of polycyclic aromatic hydrocarbons (PAHs) in water and sediment samples collected along the harbour line, Mumbai, India. The ∑PAHs quantified in water and sediment samples were ranged from 8.66 ng/L to 46.74 ng/L and from 2608 ng/g to 134134 ng/g dry wt., respectively. Significantly high concentration of ∑PAHs was found in water samples of Sewri and sediment samples of Mahul (P<0.05). PAH concentrations detected in the present study were several folds higher than the existing sediment quality criteria suggested by various statutory agencies. The PAH composition patterns in water and sediments suggest the dominance of high molecular weight compounds and indicate important pyrolytic and petrogenic sources. The occurrence of PAHs in the marine environment has attracted the attention of the scientific community as these compounds are frequently detected in seawater and sediments at increasing levels and can have adverse health effects on marine organisms and humans. PAH concentrations detected at Sewri-Mahul site were sufficiently high to pose a risk to marine organisms if they are exposed continuously to this concentration. Hence, continuous monitoring of the ecosystem is highly warranted.

The determination of lead (Pb) and cadmium (Cd) levels in sediment samples in Spermonde waters has been determined. Sampling was carried out in river and sea estuary waters. The method used in the analysis of Pb and Cd is the one specified by SNI 06-6992.3-2004 and SNI 06-6992.4-2004. Based on the Decree of the Minister of Environment No. 51 of 2004, the general condition of Spermonde waters still supports the activities of marine organisms. The results showed that Spermonde waters received more Pb metal input than Cd metal. Pb metal content in river estuary and sea waters averaged 17.38 ppm. The highest Pb metal content is found in Lanjukang Island and Bone Tambung Island, each ranging from 20.88 ppm and 20.19 ppm. Meanwhile, the lowest Pb metal content on Barang Lompo island was 9.86 ppm. The detected metal content of Cd is only found in the Barrang Lompo and Kondong islands of Bali, each ranging from 1.04 ppm and 0.19 ppm, while the other locations Cd metal are undetectable. Based on the SQG value, the content of Pb and Cd in sediments in Spermonde waters is still in the standard range for sediment that has not been contaminated.

Ballast water is one of the main vectors of transport of nuisance species among marine ports. Neither treatment nor interchange completely reduces the risk of ballast water containing DNA from harmful species, being a signal of potential threat. However, although there are some efficient treatments, they are not available on all ships and there might be some technological/economical constrains for their active and routine usage. Understanding what routes lead to a higher risk of contamination is important for designing targeted surveillance. We analysed ballast water from seven ships arriving in Gijon port (south Bay of Biscay, Spain). DNA metabarcoding was employed for identification of exotic species and harmful algae. One ship carried DNA of 20 risk species in the ballast water. Three ships contained DNA of only one risk species, and three ships had none. Seventy two algae species were found, 22.2% are exotic to the Bay of Biscay and 11.1% are catalogued as harmful. The results demonstrated the importance of continuous surveillance of ballast water.
