“…Moreover, we found that the protein band patterns by SDS-PAGE were clearly different between species, thus this may have been useful as a protein ngerprint for the taxonomic delimitation of these closely related species [32,33]. The littoral zones have rich species diversity of both macro-and microorganisms [34,35]. They comprise a front of human pressure in marine ecology and one of the most important zones for conservation [36,37].…”

Pontodrilus litoralis is a cosmopolitan littoral earthworm known to exhibit bioluminescence. Recently, a congeneric species Pontodrilus longissimus from Thailand was described. These species are sympatric but their burrowing depths on Thai beaches are different. In this study, we examined the in vivo and in vitro bioluminescence properties of P. longissimus and P. litoralis. Mechanical stimulation induced in vivo luminescence in P. litoralis, as reported previously, but not in P. longissimus. In vitro cross-reaction tests between these species revealed the absence of luciferin and luciferase activities in P. longissimus. P. litoralis had strong fluorescence in a coelomic fluid that matches to the spectral maximum of its bioluminescence, but P. longissimus did not. These results suggest that P. longissimus does not have luminescence ability due to the lack of all bioluminescent components, luciferin, luciferase, and light emitter, despite its close relationship to the luminous P. litoralis. The presence of both luminous and non-luminous species in a single genus is uncommon, and our present findings will shed insight on the possible functions of bioluminescence in the earthworm, such as avoiding predation by littoral earwigs.

Pontodrilus litoralis is a cosmopolitan littoral earthworm known to exhibit bioluminescence. Recently, a congeneric species, Pontodrilus longissimus, from Thailand was described. These species are sympatric, but their burrowing depths on Thai beaches are different. In this study, we examined the in vivo and in vitro bioluminescent properties of P. longissimus and P. litoralis. Mechanical stimulation induced in vivo luminescence in P. litoralis, as reported previously, but not in P. longissimus. In vitro cross-reaction tests between these species revealed the absence of luciferin and luciferase activities in P. longissimus. The coelomic fluid of P. litoralis had strong fluorescence that matched the spectral maximum of its bioluminescence, but the same result was not observed for P. longissimus. These results suggest that P. litoralis has luminescence abilities due to the creation of bioluminescent components (i.e., luciferin, luciferase, and light emitters). The presence of both luminous and nonluminous species in a single genus is likely widespread, but only a few examples have been confirmed. Our findings provide insight into the possible functions of bioluminescence in earthworms, such as avoiding predation by littoral earwigs.

“…Kelimpahan makroalga di alam salah satunya dipengaruhi oleh kondisi lingkungan perairan (Hurrey et al 2013;Han & Liu 2014). Umumnya, makroalga hidup di kawasan intertidal yang memiliki variasi faktor lingkungan yang cukup tinggi dibandingkan dengan bagian ekosistem laut yang lain (Satyam & Thiruchitrambalam 2018.). Beberapa faktor lingkungan yang bervariasi tersebut di antaranya seperti suhu, salinitas, substrat, dan sebagainya.…”

ABSTRAKMakroalga merupakan salah satu sumber daya hayati laut yang memiliki potensi untuk dimanfaatkan lebih lanjut oleh manusia. Penelitian ini bertujuan untuk mengkaji keanekaragaman beserta mengidentifikasi potensi pemanfaatan makroalga di area pesisir Pulau Tunda. Penelitian dilakukan pada empat stasiun dengan menggunakan metode belt transect. Hasil penelitian ini menunjukkan bahwa terdapat 15 jenis spesies makroalga yang ditemukan yang berasal dari 3 kelas makroalga yang meliputi chlorophyceae, phaeophyceae, dan rhodophyceae. Spesies makroalga yang banyak dijumpai ialah Padina minor, Halimeda macroloba, dan Gracilaria salicornia. Berdasarkan hasil perhitungan indeks keanekaragaman Shannon-Wiener, keanekaragaman makroalga tertinggi ditemukan pada stasiun 3, yakni sebesar 2,44. Berdasarkan jenis makroalga yang ditemukan di lapangan, terdapat beberapa spesies makroalga yang dapat dimanfaatkan. Kurangnya informasi terkait kandungan makroalga yang terdapat di pesisir Pulau Tunda menyebabkan belum adanya pemanfaatan makroalga oleh masyarakat setempat.
