Attractiveness of black rhinoceros (Diceros bicornis) to tsetse flies (Glossina spp.) (Diptera: Glossinidae) and other biting flies por Mihok, S., Moloo, S.K., Oden'y, J.O., Brett, R.A., Rakwar, J.G., Munyoki, E., Kiilu, J., Kyorku, C.A.

“…Any minor attractive properties of rhinoceros odours were probably due to the presence of known attractants such as 4-cresol and 3-n-propylphenol, which were confirmed to be present through gas chromatography-mass spectroscopy. In feeding trials with laboratory-reared tsetse, Glossina brevipalpis Newstead and Glossina morsitans centralis Machado fed well on immobilized animals, whereas G. longipennis fed reluctantly. …”

Algal characterization and bioaccumulation of trace elements from polluted water por Sahu, Y.K., Patel, K.S., Martín Ramos, P., Rudzińska, M., Górnaś, P., Towett, Erick K., Martín Gil, J., Tarkowska-Kukuryk, M.

“…The potentiality towards the bioaccumulation of 22 trace elements from the surface reservoir was assessed and discussed in relation to carbonate inlay of the algae wall and to the ions ability to bind to pectin, polypeptides, carotenoids, polyphenols, and flavonoids, on the basis of infrared spectroscopy data. In view of the extremely high enrichment factors found for certain elements, such as P, Co, Cu, Pb, and Fe, some of these algae hold promise as bioindicators for the detection of these elements in aquatic environments. …”
