Mira Lesmana, produser terkemuka Indonesia, membuat gebrakan dengan meliris dan menulis sendiri cerita film Ada Apa dengan Cinta 2. Kekuatan film ini tidak semata-mata bersandar dari sekuel sebelumnya, namun juga dikemas dengan aliran cerita yang menarik. Alur menggantung pada sekuel sebelumnya merupakan peluang besar untuk mengembangkan kreatifitas. Bentuk kreativitas Mira Lesmana dalam menulis cerita film ini adalah untuk mengubah karakter utama, Rangga. Karakter Rangga sengaja dibuat berbeda didasari tokoh Cinta. Perubahan karakter Rangga terjadi pada awal dan akhir cerita. Perubahan karakter Rangga dapat dilihat dari ekspresi, dialog dan tanggapan dari orang lain mengetahui sehingga dapat diketahui perubahan karakter dasar (karakter tokoh 3D) adalah fisiologis, sosiologis, dan psikologis. Perubahan karakter Rangga dapat diketahui melalui pendekatan psikologi yang didalamnya memuat karakterisasi tokoh, kostelasi tokoh, dan konsepsi tokoh. Melalui pendekatan tersebut akan nampak struktur, dinamika, dan perkembangan tokoh Rangga sehingga dapat diketahui perubahan karakter Rangga yang berdampak pada kehidupannya dalam film ini. Mira Lesmana, Indonesia's leading producer, made a breakthrough by writing  story itself and released the film “What’s Up with Love? 2”. The strength of the film is not simply leaning on the previous sequel, but also packed with interesting stories flow. Flow hang on previous sequel is a great opportunity to develop creativity. Mira Lesmana form of creativity in the writing of this movie is to change the main character, Rangga. Characters of  Rangga deliberately made different based on the character of Cinta. Rangga character changes occur at the beginning and end of the story. Character of Rangga change can be seen from the expression, dialogue and feedback from others to know that it can be seen changes in the basic character (characters 3D) is a physiological, sociological, and psychological. Rangga character change can be known through the psychological approach which includes the characterization of the figures, kostelasi character, and character conception. Through this approach would seem the structure, dynamics and character development that can be known Rangga character changes that have an impact on life in this film.

ABSTRACTTwo mixed-species bird flocks were studied in a high-altitude humid secondary forest in the Andes of Ecuador. Birds were mist-netted and colour-ringed for individual identification. The flocks (A and B) were followed to record structure, dynamics, home range and activity pattern. All observations of the two flocks studied included members from all vertical levels, which is different from flocks of Amazonia. In two nucleus species, some individuals alternated between the flocks, a feature not previously reported. Various tanagers were loosely associated, joining and leaving flocks. Minimum home-range sizes of flocks A and B were 4.2 ha and 7.8 ha, respectively. Some individuals of two species used an area encompassing the home ranges of both flocks. Mean flock sizes in A and B were 21.7 and 44.7 individuals, whereas the mean numbers of species were 13.7 and 21.7, respectively. Number of species and individuals were high compared to even most lowland flocks. Altogether, mixed-species flocks in different habitats and at various latitudinal and altitudinal sites appear to have some features in common, but others are highly distinct. Compared to the great stability of Amazonian flocks, some high-altitude flocks of secondary forest in the Andes appear to be more dynamic and unstable.

Mixed-species assemblages are often unintentionally introduced into new ecosystems. Analysing how assemblage structure varies during transport may provide insights into how introduction risk changes before propagules are released. Characterization of introduction risk is typically based on assessments of colonization pressure (CP, the number of species transported) and total propagule pressure (total PP, the total abundance of propagules released) associated with an invasion vector. Generally, invasion potential following introduction increases with greater CP or total PP. Here, we extend these assessments using rank-abundance distributions to examine how CP : total PP relationships change temporally in ballast water of ocean-going ships. Rank-abundance distributions and CP : total PP patterns varied widely between trans-Atlantic and trans-Pacific voyages, with the latter appearing to pose a much lower risk than the former. Responses also differed by taxonomic group, with invertebrates experiencing losses mainly in total PP, while diatoms and dinoflagellates sustained losses mainly in CP. In certain cases, open-ocean ballast water exchange appeared to increase introduction risk by uptake of new species or supplementation of existing ones. Our study demonstrates that rank-abundance distributions provide new insights into the utility of CP and PP in characterizing introduction risk.

The leading cause of morbidity and mortality in cystic fibrosis (CF) continues to be lung infections with Pseudomonas aeruginosa biofilms. Co-colonization of the lungs with P. aeruginosa and Burkholderia cepacia can result in more severe pulmonary disease than P. aeruginosa alone. The interactions between P. aeruginosa biofilms and B. cepacia are not yet understood; one possible association being that mixed species biofilm formation may be part of the interspecies relationship. Using the Calgary Biofilm Device (CBD), members of all genomovars of the B. cepacia complex were shown to form biofilms, including those isolated from CF lungs. Mixed species biofilm formation between CF isolates of P. aeruginosa and B. cepacia was readily achieved using the CBD. Oxidation–fermentation lactose agar was adapted as a differential agar to monitor mixed biofilm composition. Scanning electron micrographs of the biofilms demonstrated that both species readily integrated in close association in the biofilm structure. Pseudomonas aeruginosa laboratory strain PAO1, however, inhibited mixed biofilm formation of both CF isolates and environmental strains of the B. cepacia complex. Characterization of the soluble inhibitor suggested pyocyanin as the active compound.Key words: Burkholderia cepacia, Pseudomonas aeruginosa, mixed biofilms, cystic fibrosis, pyocyanin.
