The effects of refinery effluent on the invertebrate intertidal fauna and flora of Little Wick Bay, Milford Haven

The effects of continuous low level oil pollution from a refinery effluent, on intertidal fauna and flora in Little Wick Bay are investigated. A shore survey of the intertidal species on six transects at varying distances from the effluent discharge point, is carried out and the results compared with past surveys of the same transects. Any differences or similarities in the findings are related to the environmental agencies in operation since the first survey. A detailed investigation of the size classes and abundance of the Limpet Patella vulgata at each of the six transects and a quantitative analysis of Petroleum Oil Pollutants in P. vulgata by Infra red Spectrophotometry is carried out in an attempt to relate findings to the effluent discharge

Pengaruh penambahan ekstrak minyak tenggiri pada umpan bubu terhadap hasil tangkapan ranjungan di perairan Malalayang, Kota Manado

ABSTRACT Swimming crab (Portunus pelagicus) is one of the economically important marine product commodities resulting from coastal waters Indonesia. Swimming crab in coastal waters of North Sulawesi usually caught accidentally with bottom gillnet. There has been a special fishing gear for crab traps, but not known by local fishermen. Addition of mackerel oil extract on baits could increase the fishing power of swimming crab traps but this kind of scientific information, particularly on swimming crab, not widely available yet. This research aims to study the effect of mackerel oil extract on traps bait to catch swimming crab; and to identify the types of biota captured. This research was conducted in coastal waters of Malalayang Satu, Malalayang District, Manado City; in December 2014 to January 2015; which is based on experimental methods. Six units of trap were operated seven nights; where tree units of them used scad mackerel bait that injected by mackerel oil extract, and tree other units just used scad mackerel bait without mackerel oil extract; and the capture data were analyzed by t test. The catch was 58 swimming crab in total; 42 fish was caught by scad mackerel bait with mackerel oil extract, and 16 swimming crab was caught by bait without mackerel oil extract. Analysis of t test showed that the use of mackerel oil extracts in bait traps, giving different swimming crab catches compared with bait without mackerel oil extracts. Keywords: swimming crab, trap, mackerel oil, Malalayang Manado   ABSTRAK Ranjungan (Portunus pelagicus) merupakan salah satu komoditi hasil laut ekonomis penting yang dihasilkan dari perairan pantai Indonesia. Rajungan di perairan pantai Sulawesi Utara biasanya tertangkap tanpa sengaja dengan jaring insang dasar. Sebenarnya telah ada alat tangkap bubu khusus untuk rajungan, tetapi belum dikenal oleh nelayan lokal. Pemberian ekstrak berupa minyak tenggiri pada umpan diduga dapat meningkatkan kemampuan tangkap dari bubu ranjungan; namun informasi ilmiah seperti ini, khususnya pada ranjungan, belum banyak tersedia. Penelitian ini bertujuan untuk mempelajari pengaruh ekstrak minyak tenggiri pada umpan bubu terhadap hasil tangkapan ranjungan; dan mengidentifikasi jenis-jenis biota yang tertangkap. Penelitian ini dilakukan di perairan pantai Kelurahan Malalayang Satu, Kecamatan Malalayang, Kota Manado; pada bulan Desember 2014 sampai bulan Januari 2015; yang didasarkan pada metode experimental fishing. Enam unit bubu dioperasikan tujuh malam; di mana tiga unit menggunakan umpan ikan layang yang disuntikkan ekstrak minyak tenggiri, dan tiga unit lainnya hanya menggunakan umpan ikan layang tanpa ekstrak; dan data dinalisis dengan uji t. Tangkapan total berjumlah 58 ekor; 42 ekor tertangkap dengan umpan layang yang diberi ekstrak minyak tenggiri, dan 16 ekor tertangkap dengan umpan tanpa ekstrak minyak tenggiri. Hasil analisis uji t menunjukkan bahwa penggunaan ekstrak minyak tenggiri pada umpan bubu memberikan hasil tangkapan ranjungan yang lebih banyak dibandingkan dengan umpan tanpa ekstrak minyak tenggiri. Kata-kata kunci: rajungan, bubu, minyak tenggiri, Malalayang Manado. [1] Penulis untuk penyuratan; email: [email protected]

ImmPort, toward repurposing of open access immunological assay data for translational and clinical research

Immunology researchers are beginning to explore the possibilities of reproducibility, reuse and secondary analyses of immunology data. Open-access datasets are being applied in the validation of the methods used in the original studies, leveraging studies for meta-analysis, or generating new hypotheses. To promote these goals, the ImmPort data repository was created for the broader research community to explore the wide spectrum of clinical and basic research data and associated findings. The ImmPort ecosystem consists of four components–Private Data, Shared Data, Data Analysis, and Resources—for data archiving, dissemination, analyses, and reuse. To date, more than 300 studies have been made freely available through the ImmPort Shared Data portal , which allows research data to be repurposed to accelerate the translation of new insights into discoveries

Women’s representation in national science academies: An unsettling narrative

Science academies are well placed to contribute towards strengthening of national systems of innovation through advocating for an increased participation of girls and women in science. To successfully do so, academies would need to overcome challenges faced with regard to women’s representation in their own ranks and women’s resultant full participation in the activities of national science academies. We collected baseline data on the representation of women scientists in the membership and governance structures of national science academies that are affiliated with IAP: the Global Network of Science Academies. Women academy members remained far below parity with men, given that women’s membership was typically about 12%. Women members were better represented in the social sciences, humanities and arts but the corresponding shares rarely exceeded 20%. In the natural sciences and engineering, women’s membership remained well below 10%. On average, the largest share of women members (17%) was associated with academies in Latin America and the Caribbean. The average share of women serving on governing bodies was 20%. To change this unsettling narrative, the importance of academies of science annually collecting, analysing and reporting gender-disaggregated data on membership and activities is highlighted as a key recommendation. Several aspects of women’s representation and participation in national science academies are highlighted for further investigation
