Abstract

The study aims to report the occurrence and to present photo-identification of killer whales (Orcinus orca) in the Gulf of Tomini. This article is an attempt to provide basic data for further research on cetacean in Indonesia. The study was conducted from February 2017 to February 2019 in waters along the coast of Gorontalo Province in the Gulf of Tomini. Recorded videos and photos were collected, and interviews were conducted with fishers and tour guides. Observations were made at coastal waters near the villages where the occurrence of killer whales has been reported. Focus group discussions were held in a number of places in the study area by utilizing local traditional ecological knowledge. Data were analyzed in a descriptive-qualitative approach. The date of occurrence is sorted chronologically at each location. Photographs or videos were captured for photo-identification. The results showed that the occurrence of killer whales are almost evenly distributed throughout the year regardless of the monsoons. Killer whales usually appear in pods of up to five individuals, with a few exceptions of solo appearances. The resulting photo-identification displays four individuals from four different pods.

Abstract

Sel darah putih merupakan sel yang sensitif terhadap infeksi dan perubahan lingkungan. Penelitian ini menyelidiki efek paparan jangka panjang terhadap medan Extremely Low-Frequency (ELF-MF) pada 50 Hz dan 100 μT terhadap komposisi leukosit mencit BALB/C, dengan fokus pada neutrofil, monosit, dan limfosit. Dua puluh empat tikus BALB/C jantan dibagi menjadi kelompok kontrol, 15 hari, dan 30 hari paparan, dengan paparan intermiten setiap hari selama 2 jam. Jumlah leukosit dianalisis menggunakan ANOVA satu arah.Hasilnya menunjukkan perubahan signifikan pada populasi leukosit. Jumlah neutrofil meningkat secara progresif setelah 30 hari, yang menunjukkan adanya potensi respons inflamasi. Tingkat monosit menunjukkan dua tahap, awalnya menurun pada hari ke-15 lalu melonjak 82,3% pada hari ke-30, yang menunjukkan aktivasi kekebalan adaptif. Sebaliknya, jumlah limfosit tetap stabil hingga hari ke-15 tetapi menurun secara signifikan sebesar 2,14% pada hari ke-30, yang berpotensi mencerminkan modulasi kekebalan yang diinduksi oleh stres.Temuan ini menyoroti radiasi ELF-MF dapat mengubah dinamika leukosit, kemungkinan dimediasi melalui jalur stres oksidatif dan respons inflamasi yang berkepanjangan. Perubahan ini menggarisbawahi pentingnya penelitian lebih lanjut tentang implikasi kesehatan jangka panjang dari paparan ELF-MF, mengingat meningkatnya prevalensi radiasi elektromagnetik di lingkungan modern.

Abstract

The Apocynaceae family, including Tapak Dara (Catharanthus roseus), is one of the most popular medicinal plants due to its secondary metabolites. Secondary metabolites are naturally produced in small amounts, but have very high economic value. Therefore, exploration of plant species within the same family is an interesting issue to be conducted. The purpose of this study is to discover members of the Apocynaceae family that have close relatives with Catharanthus roseus so that expected to have the similar active compounds. The method used was phylogenetic analysis using DNA sequences of maturase K (matK) and riboluse 1,5-biphosphate carboxylase/oxygenase large subunit (rbcL) regions. A total of 22 plants of the Apocynaceae family were used, and the sequences of both genes from these plants were retrieved in the NCBI database. Phylogenetic tree was constructed using MEGA 11 and two Rubiaceae species as outgroups. The study results showed that 10 plant groups were formed based on the suprageneric in both trees generated. It is consistently obtained that Rauvolfia serpentina is in one group with Catharanthus roseus in the Vinceae tribes of Rauvolfioideae subfamily. Morphologically, this group of plants has similar flower and leaf characters. It can be conclude that phylogenetic analysis with DNA sequences supports the grouping of morphological data, and indicates that R. serpentine has a biochemical profile similar to Tapak Dara.
