Pyricularia costina and three undescribed Pyricularia species were found as endophytes on wild ginger Amomum siamense and Alpinia malaccensis in Doi Suthep-Pui National Park, Chiang Mai, Thailand. Three new species, Pyricularia kookicola, P. longispora, and P. variabilis are described, illustrated and compared to similar Pyricularia species.

Three strains of cyanobacteria (Anabaena PCC7120, A. variabilis and Nostoc commune), all belonging to the family Nostocaceae, were found to be capable of modulating the production and chemical composition of extracellular polysaccharides (EPS) in response to carbon and nitrogen availability as well as pH. While the carbohydrate compositions of the glycans produced by the different organisms wer...

For sessile marine invertebrates, processes contributing to larval release, dispersal, and settlement in favourable habitats are central to patterns of distribution and community structure. We quantified larval release patterns, phototactic behaviour, and settlement in response to environmental cues for the coral reef sponge Luffariella variabilis. Individual sponges released up to 830 larvae d...
