In marine organisms, pelagic larval dispersal often results in genetic panmixis among widely separated populations; however, local conditions may produce populations of organisms that differ key life history traits. Here, we assess spatial differences growth, body condition, survivorship and movement over a decade for lemon damselfish Pomacentrus moluccensis. Newly recruited fish were tagged on...

Dampak dari cemaran mikroplastik ini sangat berbahaya, terlebih lagi jika masuk kedalam jaringan tubuh hewan bahkan manusia. Keberadaan semakin meningkat seiring meningkatnya ketergantungan aktifitas manusia terhadap plastik. Kandungan dalam pencernaan ikan perlu diketahui mengingat tingginya konsumsi laut lokal di perairan Teluk Palu. Tujuan penelitian adalah menghitung konsentrasi pada sistem...

Many cultivated and natural fruits play an important role both in food security and in meeting nutritional requirements in households throughout PNG. Fruit fly species of the family Tephritidae account for significant preharvest and postharvest food losses, and a reduction of these losses will improve food availability at household levels. The Papua New Guinea Fruit Fly Project (PNGFFP) has con...

Ultraviolet radiation (UVR) reaching the surface of earth has been recognized as a major environmental stressor for marine organisms due to the potential of UVB (280 315 nm) to induce DNA damage such as cyclobutane pyrimidine dimers (CPDs) that can lead to cell death. Despite inhabiting a UV-rich environment, the levels of DNA damage in reef fish and factors influencing these levels are unknown...

Although phototaxis has an important influence on the vertical distribution and settlement of marine invertebrate larvae, few studies have explored the mechanisms of taxis in larvae at the organismal level. We examined how phototaxis changes over ontogeny in larvae of the ascidian Aplidium constellatum and experimentally tested hypotheses about the kinematics of oriented swimming. By video reco...

The disjunct zonation pattern of Avicennia marina (Forsk.) Vierh., frequently observed along the Kenyan coast as a landward and a seaward zone, has been studied on a morphological level and complemented with preliminary genetic data. The objective was to describe the two zones in-depth in order to provide a background ecological setting that may be used in explanations on the emergence of such ...
