Ramsar site designation is an acknowledgment of a wetland’s importance. In this study, we conducted biodiversity survey around Natuna to examine its eligibility as the next in Indonesia. This was through sampling for biological resources, using either transect, trapping, or visual observation. We surveyed 32 stations endangered and vulnerable fish, water birds, wetland-dependent species. Sample...

Thellungiella halophila (T. halophila) (salt cress) is a close relative of Arabidopsis and a model plant for salt tolerance research. However, the nature of its later flowering causes some difficulties in genetic analysis. The FRIGIDA (FRI) gene plays a key role in the Arabidopsis vernalization flowering pathway, whose homolog in T. halophila may also be a key factor in controlling flowering ti...

Peningkatan emisi Gas Rumah Kaca (GRK) terutama karbondioksida (CO2) menyebabkan pemanasan global. Oleh karena itu diperlukan mitigasi CO2 dengan memanfaatkan potensi lamun sebagai penyimpan karbon dalam bentuk biomassa. Tujuan penelitian ini untuk mengetahui kemampuan jaringan atas dan bawah menyimpan di perairan Pantai Pokemon pada Agustus 2020. Metode yang digunakan yaitu metode survei deskr...

Extreme climate events are predicted to alter estuarine salinity gradients exposing habitat-forming species more frequent variations. The intensity and duration of these variations, rather than the mean values ecosystems exposed to, may be important in influencing resilience but requires further investigation. Precipitation, including frequency, timing occurrence, is shifting due change. A glob...

As white spot syndrome virus (WSSV) can be highly pathogenic in penaeid shrimp, various feed supplements have been tested to help to protect farmed shrimp against WSSV disease. Here a polysaccharide extract from Halophila ovalis (HO) seagrass was added to feeds at concentrations of 0.25, 0.5, and 1.0 g[a1] /kg to assess its ability to protect Black Tiger shrimp (Penaeus monodon) against WSSV ch...

Accurate and up-to-date maps of seagrass biodiversity are important for marine resource management but it is very challenging to test the accuracy of remote sensing techniques for mapping seagrass in coastal waters with variable water turbidity. In this study, Worldview-2 (WV-2) imagery was combined with field sampling to demonstrate the capability of mapping species type, percentage cover, and...
