Even though the Indo-Malay Archipelago hosts world's greatest diversity of marine species, studies on genetic population structure and gene flow organisms within this area are rather rare. Consequently, not much is known about connectivity populations in Archipelago, despite fact that such information important to understand evolutionary ecological processes centre biodiversity. This study aims investigate boring giant clam, Tridacna crocea. The analysis based a 456-bp fragment cytochrome...

Information on the genetic population structure of endangered giant clams is important for conservation programmes and understanding ecological evolutionary processes. In this study, structures three codistributed ecologically similar clam species (Tridacna crocea, T. maxima squamosa) are compared. A fragment cytochrome c oxidase I gene was sequenced as a marker in sampled throughout Indo-West Pacific, from Western Indian Ocean (WIO) Red Sea (RS) to Eastern (EIO), across centre marine...

The long-term behavior of atmospheric tides in the mesosphere and lower thermosphere has been observed with meteor wind radar (MWR) Jakarta, Indonesia (6°S, 107°E) from November 1992 to August 1997. amplitudes phases diurnal show systematic seasonal variations, particularly distinct meridional component. In addition, substantial interannual variability is evident, characterized by a biennial periodicity tidal parameters, considerably small exclusively seen 1996. MWR results are compared...

Abstract Aim The aim of this study was to test historical and contemporary influences on population structure in the giant clams, Tridacna maxima (Röding, 1798) T. crocea (Lamarck, 1819). To refine location clade boundaries within a newly resurrected species, noae 1798).

Abstract Mitochondrial DNA (mt ) is a single, usually non‐recombining locus, and often uniparentally inherited. Therefore, its ability to reveal recent gene flow among populations questioned. In this study, the genetic population structure of 16 Tridacna crocea (n = 366) from Indo‐Malay Archipelago ( IMA was examined with 10 microsatellite markers compared previous studies using mt , in order test if revealed congruent between two marker systems. The results showed that by systems mostly...

We studied the behavior of intraseasonal oscillations (ISO) zonal wind velocity in equatorial mesosphere and lower thermosphere (MLT) using simultaneous observations during 500 days from 1 January 1996 with a meteor radar at Jakarta (6°S, 107°E) two medium‐frequency radars Pontianak (0°N, 109°E) Christmas Island (2°N, 157°W). Cross‐correlation analysis ISO 88 km indicated that phase difference between is, on average, small spite longitudinal ∼90°. Therefore MLT region seems to be variation...
