“…This has raised the concern over the ecological implication of coral biological resources (Ferse et al, 2012). Morphotypes Isis hippuris is an ecological divergence and acts as the anthropogenic indicator that thrives on the mechanism of biodiversity and coral health in the Coral Triangle (Rowley, 2018).…”

Today, the forest is a key element of natural resources, the most complex natural (ecological) system in the continent. Because of its environmental impact, it is also a vital condition for healthy human life. In addition to its dominant role in regulating the quantity and quality of waters, the forest defines the nature of the landscape, preserves the richness of wildlife species and, being a renewable natural resource, continuously improves the state of the environment, while producing raw materials, energy sources and food. The present area and condition of forests have evolved over centuries of human activity. Due to their territorial fragmentation and the environmental damage forests are exposed to, we can only count on the indispensable survival, protective effect and products (yields) of forest communities if we treat them professionally and protect them from damaging effects, excessive use and stress, ensuring the diversity and appropriate harmony of their flora and fauna. The forest area of Hungary has grown dynamically over the last decades, however, in the European Union, we are one of the countries with less favourable indicators in this field. This study deals with the current issues of forest management in Hungary (forest area, forest land proportion, foresttree supply, afforestation, forest health, logging) focusing on the direction and extent of positive and negative changes in this field.

“…Bambu laut merupakan salah satu organisme penyusun terumbu karang yang masuk dalam kelas Octocorallia (Alcyonaria). Bambu laut merupakan suku Gorgonacea yang merupakan kelompok karang lunak yang banyak ditemukan di perairan tropis (Rowley, 2018). Gorgonian Isis hippuris dilaporkan berpotensi untuk dieksplorasi karena mengandung sejumlah besar bioaktif yang diklasifikasikan menjadi polioksigenasi steroid, hidrokarbon, fenol dan asam lemak.…”

Bambu laut (Isis hippuris) merupakan salah satu organisme laut penyusun ekosistem terumbu karang yang dilaporkan berpotensi sebagai sumber bahan bioaktif. Bambu laut mengandung bioaktif polioksigenasi steroid, hidrokarbon, fenol dan asam lemak. Penelitian ini bertujuan mengonfirmasi komponen bioaktif dari ekstrak bambu laut. Sampel bambu laut dikoleksi dari perairan Kabupaten Donggala, Sulawesi Tengah, dengan kondisi cuaca cerah. Pada sampel bambu laut dilakukan proses ekstraksi (maserasi MeOH : DCM), skrining komponen bioaktif (metode Harborne), dan determinsi kandungan total alkaloid (ekuivalen kafein - CE), fenol (ekuivalen asam galat - GAE), flavonoid (ekuivalen kuersetin - QE), dan steroid (ekuivalen kolesterol - ChE). Hasil skrining komponen bioaktif menunjukkan ekstrak bambu laut (I. hippuris) mengandung sejumlah komponen alkaloid, fenol, steroid dan flavonoid. Ekstrak bambu laut mengandung alkaloid 11,61 ± 0,24 mg CE.g-1 ekstrak kering; fenol sebesar 18,92 ± 0,24 mg GAE.g-1 ekstrak kering; flavonoid sebesar 21,24 ± 0,28 mg QE.g-1 ekstrak kering; dan steroid sebesar 36.94 ± 1.39 mg ChE.g-1 ekstrak kering. Penelitian ini mengonfirmasi keberadaan komponen bioaktif ekstrak bambu laut (I. hippuris) yang dikoleksi dari perairan Sulawesi Tengah. Hasil skrining komponen bioaktif menunjukkan kehadiran komponen alkaloid, fenol, steroid dan flavonoid. Oleh karena itu, perlu diidentifikasi lebih lanjut senyawa bioaktif (diduga turunan steroid, alkaloid dan fenolik) yang terkandung dari ekstrak bambu laut.

“…Variation in sclerite morphology may be altered in response to depth, water motion, light levels, and environmental factors such as predation pressure (West, 1997). Morphological differences may be a response to environmental factors (Rowley, 2018), but can also be attributed to accumulated genetic differences, due to the disruption of gene flow among populations (Prada et al, 2008).…”

Peer Review #3 of "Ocean warming is the key filter for successful colonization of the migrant octocoral Melithaea erythraea (Ehrenberg, 1834) in the Eastern Mediterranean Sea (v0.1)"

Climate, which sets broad limits for migrating species, is considered a key filter to species migration between contrasting marine environments. The Southeast Mediterranean Sea (SEMS) is one of the regions where ocean temperatures are rising the fastest under recent climate change. Also, it is the most vulnerable marine region to species introductions. Here, we explore the factors which enabled the colonization of the endemic Red Sea octocoral Melithaea erythraea Ehrenberg, 1834 along the SEMS coast, using sclerite oxygen and carbon stable isotope composition (δ 18 O SC and δ 13 C SC), morphology, and crystallography. The unique conditions presented by the SEMS include a greater temperature range (~15 °C) and ultra-oligotrophy, and these are reflected by the lower δ 13 C SC values. This is indicative of a larger metabolic carbon intake during calcification, as well as an increase in crystal size, a decrease of octocoral wart density and thickness of the migrating octocoral sclerites compared to the Red Sea samples. This suggests increased stress conditions, affecting sclerite deposition of the SEMS migrating octocoral. The δ 18 Osc range of the migrating M. erythraea indicates a preference for warm water sclerite deposition, similar to the native depositional temperature range of 21-28 °C. These findings are associated with the observed increase of minimum temperatures in winter for this region, at a rate of 0.35±0.27 °C decade-1 over the last 30 years, and thus the region is becoming more hospitable to the Indo-Pacific M. erythraea. This study shows a clear case study of "tropicalization" of the Mediterranean Sea due to recent warming.
