BACKGROUND Ascidians play a key role in the ecology and biodiversity of marine ecosystem. Ascidians can be transported in ship ballast water and while attached to ship and boat hulls. Heavy traffic by domestic and international ships as well as cargo vessels between the major and minor ports warrants continuous monitoring for new introductions of ascidians. The Mandapam coast is situated in the...

Symplocarpus koreanus (Araceae; Orontioideae) from Korea is described as new. has long been considered to be conspecific with S. renifolius in Japan, but phylogenetic, morphological, and cytological data indicate its taxonomic distinction. Compared renifolius, a much smaller spathe more spherical spadix fewer, flowers. Previous phylogenetic studies also suggested that closely related nonthermog...

A circadian rhythm in CO2 production was observed in three cultivars of Anthurium andraeanum Andre (‘Jaya’, ‘Fla-range’, ‘Leonette’) flowers. The rhythmicity was not affected by light, darkness, and detachment. However, the amplitude was dampened in darkness and after detachment. Spadix respiration accounted for 90% of the total flower respiration. Rhythmicity in CO2 production continued after ...

Skunk cabbage (Symplocarpus renifolius) blooms in early spring and its inflorescence, referred to as the spadix, can produce enough heat to melt snow. Here, we investigated glycolytic carbon flow at the PEP branch-point in thermogenic spadices. Our analyses revealed that petals and pistils in thermogenic florets exhibited higher expression of SrPEPC and SrAOX transcripts than those of SrPK, SrP...

Abstract In an attempt to increase the biodiversity of natural fibers, new sources fibers should be discovered. Long textile-grade date palm (DP) were used in manufacturing 50:50 polypropylene nonwoven composite. DP are considered newcomers fiber library. The main aim this work was benchmark different types composites comparison other commercial leaf composites, namely, sisal, abaca, and banana...

The "bunga bangkai" is a compound interest with spadix and solitary inflorescences. Amorphophallus gigas one of several species which endemic to Sumatra. One the original habitats for A. found in North Padang Lawas bloom almost all year round. This study aimed observe phenology Regency, precisely Bargottopong Village was on rubber agroforestry land communities. Observations were made every 3 da...
