Tujuan penelitian untuk mengetahui aktivitas toksisitas minyak atsiri kulit kayu sintok (C. sintoc Blume) kondisi segar dan kering terhadap larva A. salina Leach. Menggunakan metode destilasi mendapatkan atsirinya, kemudian diuji toksisitasnya dengan menggunakan Brine Shrimp Lethality Test (BSLT), analisis senyawa GC-MS. Kematian dianalisis Regresi Probit. Hasil menunjukkan, bersifat toksik. Mi...

Fast-starts are brief accelerations commonly observed in fish within the context of predator-prey interactions. In typical C-start escape responses, fish react to a threatening stimulus by bending their body into a C-shape during the first muscle contraction (i.e. stage 1) which provides a sudden acceleration away from the stimulus. Recently, similar C-starts have been recorded in fish aiming a...

BACKGROUND Despite extensive research in the last decades, microalgae are still only economically feasible for high valued markets. Strain improvement is a strategy to increase productivities, hence reducing costs. In this work, we focus on microalgae selection: taking advantage of the natural biological variability of species to select variations based on desired characteristics. We focused on...

A sex pheromone, protoplast-release-inducing protein (PR-IP) inducer, of the Closterium peracerosum-strigosum-littorale complex is known to induce the release of PR-IP, from mating-type plus (mt+) cells during sexual reproduction. The purified PR-IP inducer was treated with trypsin to obtain internal peptides for determination of partial amino acid sequences. Using these sequences, oligonucleot...

The information content of prices is a central problem in the general equilibrium analysis of competitive markets. Rational expectations equilibrium identifies conditioning simultaneously on contemporaneous prices and private information as the mechanism by which information enters prices. Here we look to the ecology of markets for an explanation of the information content of prices. Markets co...
