Determination of heavy metals is enormously important to determine the condition aquatic environment in terms chemical pollution. In this study, a preliminary determination metal concentrations sediment, water, and some macroinvertebrates several sampling sites along Tawi-Tawi Bay, Philippines, was undertaken have an initial status pollution area. Results revealed that average concentration fol...

To describe patterns of gene flow for the fished holothurian species Holothuria scabra 17 to 141 individuals were collected from 8 populations from north-east Australia, the Torres Strait, and the Solomon Islands. Samples were investigated by allozyme electrophoresis of 7 polymorphic loci. Cluster analyses using Rogers’ genetic distance identified 3 distinct groups of populations from the north...

The cytotoxic effects of thirteen triterpene glycosides from Holothuria scabra Jaeger and Cucumaria frondosa Gunnerus (Holothuroidea) against four human cell lines were detected and their cytotoxicity-structure relationships were established. The apoptosis-inducing activity of a more potent glycoside echinoside A (1) in HepG2 cells was further investigated by determining its effect on the morph...

This study was designed to investigate whether thermotolerant roots exhibit respiratory acclimation to elevated temperatures. Root respiratory acclimation traits in response to increasing temperatures were compared between two Agrostis species contrasting in heat tolerance: thermal A. scabra and heat-sensitive A. stolonifera. Roots of both species were exposed to 17, 27, or 37 degrees C. Root R...

In this study, commercial sea cucumber identification and some biological characteristics were investigated between Ayvalık and Çeşme. Ayvalık, Aliağa, Foça, Şakran and İzmir were selected as main stations. In the investigation where 70 stations were studied between 0 and 50 m depth 6 sea cucumber species were found. These were Holothuria tubulosa, Holothuria polii, Holothuria mammata, Holothur...
