Population Genetic Structure of Marine Leech, in Indo-West Pacific Region.

Grouper aquaculture is rapidly expanding in both tropical and subtropical regions. The presence of marine leeches (; previously named ) infesting cultured groupers, however, can have a fatal effect on grouper aquaculture production and cause significant economic loss. Understanding the marine leech's population structure is therefore important to determine its possible distributional origin and distributional mechanisms, which will help monitor and mitigate the infestation.

Vegetative Propagation of and by Stem Cutting and Micropropagation.

Contrasting patterns of genetic population structure in tropical freshwater eels of genus in the Indo-Pacific.

Freshwater eels, genus , have a distinctive catadromous life history, which could be associated with certain oceanic current systems and offshore spawning sites. Thus, migration and dispersion patterns are believed to be important factors influencing the population structure of each species. Temperate eel species are well studied, while little research has been conducted on the tropical counterparts that comprise two-thirds of all eel species.

Uptake of nicotine from discarded cigarette butts - A so far unconsidered path of contamination of plant-derived commodities.

This study aimed to elucidate the origin of the widespread nicotine contamination of plant-derived commodities, by conducting field experiments with various herbs and spice plants. By scattering tobacco and cigarette butts on the field and subsequent nicotine analyses of the acceptor plants, we verified that the alkaloid is leached out into the soil and is taken up by the crop plants. This path of contamination pertains even when there is only one cigarette butt per square meter.
