Steady-state dynamics and effective temperatures of quantum criticality in an open system

We study the thermal and non-thermal steady state scaling functions and the steady-state dynamics of a model of local quantum criticality. The model we consider, i.e. the pseudogap Kondo model, allows us to study the concept of effective temperatures near fully interacting as well as weak-coupling fixed points. In the vicinity of each fixed point we establish the existence of an effective temperature --different at each fixed point-- such that the equilibrium fluctuation-dissipation theorem is recovered. Most notably, steady-state scaling functions in terms of the effective temperatures coincide with the equilibrium scaling functions. This result extends to higher correlation functions as is explicitly demonstrated for the Kondo singlet strength. The non-linear charge transport is also studied and analyzed in terms of the effective temperature.Comment: 5 pages, 4 figures; Supplementary Material (7 pages, 1 figure

PERKEMBANGAN LARVA DALAM EMBRIOGENESIS KARANG Acropora HASIL PEMIJAHAN EX-SITU

Fertilization and larval development determine the coral population survivalof species, which has adifference characteristic of embryogenesis. This research wasaimed to compare the embryo and larvaldevelopment spawned in November 2011 in Grear Barrier Reef, Australia.Embryonic cellsdevelopment wereobserved in interval timesfrom one cell of egg tomulticellular stage (prawnchip), and larval developmentobserved from the prawnchip stageto the planulae.The results showed the development of embryos and larvaesignificantly differed between two species, i.e. embryos and larvae of Acropora millepora grew faster thanA.tenuis. The maximum size of planulae larvae of A. millepora (800-1000 μm) is biggerthan A. tenuis (650-900μm). Embryo and larvae development were different due to species variability, hence this reseach can beadapted for laboratory proccess of coral larvae nursery.

Microhabitat Preference of Seastar in Hari Island Waters, Southeast Sulawesi

The objective of this study was to explore the information on the microhabitat preference of asteroidea in Hari Island Waters, Southeast Sulawesi. The specimens were collected in August 2012 and December 2012. The methods used in this study were road sampling technique, freehandpicking, and observation. The geographical coordinate position of the asteroidea and microhabitat were recorded by using GPS and then mapped by using the ArcGIS 10.1. Asteroidea map was overlayed with microhabitat map to determine the microhabitat preference. The study found 9 species of asteroidea belonging to 7 generas, 4 families, and 2 orders. All the asteroidea were relatively common species in the tropical shallow waters. The species were distributed along sides of the island with majority found in the northern side. The dominant species, Linckia laevigata, was found in all microhabitat which had beed adapted to various microhabitat conditions and water fluctuation. Based on area of distribution and population density, seastar tended to use reef coral as its microhabitat preference since reef coral could serve as a food source and habitat protection

Variasi Temporal Kelompok Ikan Terumbu Karang di Pulau Tidung Kecil Menggunakan eDNA Metabarkoding dan Sensus Visual

Coral reef fish are play key role in coral reef ecosystem. The presence of reef fish affected by antrophogenic and natural factors, such seasonal changes. This study aimed to asess the temporal variation of coral reef fish group in Tidung Kecil Island using eDNA metabarcoding and Undewater Visual Census. This research was conducted at December 2019 (West season) and August 2020 (East season). Target group are dominated in west season (64.1%) and east season (59.25%) using eDNA metabarcoding. While, major group fish are the highest relative abundance in both season by using Underwater Visual Census. Family Carangidae are the highest species richness (15 species) in wet season and Serranidae (3 species) in east season, respectively.  Futhermore, famili Pomacentridae are the most richness species in west and east seasons 10 and 11 species respectively. Thus, it can be concluded these two methods are effective for monitoring structure or abundance of coral reef fish based on seasonal variation. Ikan karang menjadi indikator dalam menilai keanekaragaman hayati di ekosistem tersebut. Keberadaan ikan di ekosistem terumbu karang dapat dipengaruhi oleh faktor antropogenik dan faktor alam salah satunya perubahan musim. Penelitian ini bertujuan untuk menganalisis kelimpahan kelompok ikan terumbu karang di Pulau Tidung Kecil menggunakan eDNA metabarkoding dan Sensus Visual. Pengambilan data dilakukan pada bulan Desember 2019 (musim barat) dan Agustus 2020 (musim timur). Ikan target mendominasi pada musim barat dan timur dengan persentase sebesar 64.11% dan 59.25%. Sensus visual berhasil mendeteksi ikan mayor dengan persentase tertinggi 62.5% di musim barat dan 82.8% di musim timur. Famili Carangidae merupakan famili dengan jumlah spesies tertinggi di musim barat (15 species) dan Siganidae di musim timur menggunakan eDNA metabarkoding (3 species). Hasil UVC menunjukkan famili Pomcentridae memilki jumlah spesies tertinggi di kedua musim (11 dan 10 spesies) menggundakan sensus visual. Dapat disimpulkan bahwa kedua metode tersebut dapat menjadi pendekatan dalam monitoring struktur atau kelimpahan ikan terumbu karang berdasarkan musim.

Intestinal DNA concentration and protein synthesis in response to low quality diets in two strains of Leghorn layers

Performance, protein synthesis and mucosal DNA in small intestine of Leghorn hens may be affected by low quality feedstuff. An experiment was conducted in completely randomized design (CRD) in 2 × 2 factorial arrangement. Main factors included diets containing 20 and 40 % barley and black and blue strains of leghorn. Layer performance was recorded weekly up to eight weeks. Egg production (%), egg mass and egg number were significantly higher in black strain leghorn on 20% barley diet than blue strain with 40% barley diet (P<0.05). Treatments blue × 40% barley and black × 20% barley showed lowest and highest egg production percentage, egg mass and egg number, respectively (P<0.05). The lowest protein synthesis in small intestine was shown in blue × 40% barley treatment group. Small intestine mucosal DNA quantity in blue strain was significantly higher than that in black strain (P<0.05). In contrast, protein synthesis in blue strain was lower than that in black strain (P<0.05). It was concluded that lower performance in blue × 40% treatment group could be related to lower protein synthesis in small intestine in blue strain, and this may be due to the high barley (40%) contained in diet.Key words: Performance, protein synthesis, mucosal DNA, small intestine

GROWTH RATE, SPATIAL-TEMPORAL VARIATION AND PREVALENCE OF THE ENCRUSTING CYANOSPONGE (Terpios hoshinota) IN SERIBU ISLANDS, JAKARTA

Terpios hoshinota is a cyanosponge encrusted on the substrate in coral reefs that may cause mass mortality on the infested corals. This research was conducted to investigate the magnitude of damage level of corals due to the T. hoshinota outbreaks by assessing its growth rate, spatiotemporal variation, and prevalence between two sites in Seribu Islands. Four-time observation (T0-T3) in over 18 months (2016-2017) was conducted to see the growth level of sponge using a permanently quadratic photo transect method of 5x5 m (250.000cm2). The total coverage area of sponge on study site in the T0 was 65.252cm2 and becomes 81.066cm2 in T3. The highest level occurred on T2 of 2.051cm2/months in Dapur Island (the closest to Jakarta) and 483cm2/months in the Belanda Island (the further site). The highest sponge growth rate occurred on T1-T2 during transitional season from rainy to dry. The lowest growth rate was observed on T3 during transitional season from dry to rainy. In general, prevalence percentage was higher in Belanda Island than in Dapur Island. This study showed a persistence invasion of encrusting T. hoshinota on coral reef ecosystem that may overcome the function and role of associated organisms.Terpios hoshinota adalah cyanosponge bertatahkan pada substrat di terumbu karang yang dapat menyebabkan kematian massal pada karang yang terpapar. Penelitian ini dilakukan untuk menyelidiki besarnya tingkat kerusakan karang akibat wabah T. hoshinota dengan menilai tingkat pertumbuhan, variasi spasial, dan prevalensi antara dua lokasi di Kepulauan Seribu.
