Identify of a tilapia pheromone released by dominant males that primes females ...
Keller-Costa, T.; Hubbard, Peter; Paetz, Christian; Nakamura, Yoko; Silva, José P. da; Rato, Ana; Barata, E. N.; Schneider, BerndKnowledge of the chemical identity and role of urinary pheromones in fish is scarce, yet necessary to understand the integration of multiple senses in adaptive responses and the evolution of chemical communication. In nature, Mozambique tilapia (Oreochromis mossambicus) males form hierarchies and females mate preferentially with dominant territorial males which they visit in aggregations or leks.
Solution and surface photochemistry of fenarimol: A comparative study
Silva, José P. da; Mateus, M. Conceição D. A.; Silva, Abílio M. da; Ferreira, Luís F. Vieira; Burrows, Hugh D.The photochemistry of the pesticide fenarimol was studied in methanol and on a cellulose surface. The ground state absorption and fluorescence spectra are similar in solution and at the solid/gas interface. Room temperature phosphorescence emission was observed in cellulose. Transient absorption of fenarimol and of its chromophoric units, chlorobenzene and pyrimidine, showed a common absorption band centered at...
