The javan green peafowl (Pavo muticus muticus) is a endangered bird species. They have big pressure to the population and the habitat. The fact that the birds are still exist on their local distribution. Behavior ecology of javan green peafowl is dealing with activities, mechanism and strategies of the birds in relation to their environment. The aimed of the study is to obtain data and information of ecological adaptation strategies through the behavior activities, mechanism and strategies of javan green peafowl in-relation to their habitat types. Ad libitum sampling method was used on continuous recording every peafowl activities in relation with duration, frequencies mechanism and strategy were influenced by habitat type’s condition. Chi-squre test was used for statistical analysis to know different behavior has influenced by habitat types. The result shown that the javan green peafowl habitat typse has significant influenced on duration of the activities but not at the activities pattern. The walking during the feeding, select shading places or luxuriant trees close to feeding site, choosing tall trees or emergent trees close to open area as roost site, open area also road as display or dancing area, open area which grow shrubs as nesting site are javan green peafowl ecological behavior strategies. The mechanism and strategies of javan green peafowl behavior ecology are related to avoid from disturbance and to adapt their habitat type’s conditions.

Cinchona alkaloids are in extensive uses, not only for drugs but also for soft drink industries. They are harvested from the bark of trees Cinchona spp. after certain ages and therefore are available over a limited time. Cell culture is an alternative way to continuously produce such secondary metabolites in a much shorter time. Various substances were added in the normal growth media to promote quinoline alkaloids production by cell cultures of Cinchona ledgeriana. At the sixth week of culture, quinine and cinchonine contents were suppressed by paclobutrazol (PBZ), abscisic acid (ABA), or even by precursor tryptophan, while cinchonidine content was enhanced by 0.2 mg/l tryptophan to 43 fold of that produced by untreated cells (2.8% dry weight). At the seventh week of culture, the production of quinine and quinidine started to grow whereas the production of cinchonine and cinchonidine tended to decrease. An addition of 5 mg/l PBZ to culture media yielded the highest level of total quinine/quinidine after seven weeks, e.g. quinine 11 times more abundant and quinidine 23 fold higher compared to the untreated cells. Particularly the level of quinine which is the most demanded for medical and industrial purposes still need to be improved to approach to or even higher than that of extracted from the conventional source.
