Bioindication is defined as the indication of ecological quality based on composition of organisms of a habitat. The basis forms the knowledge of the relationship between organisms and habitat conditions. The history of bioindication using Charophytes is described. Charophytes have mainly been used for the indication of trophic status.

Allometrische Untersuchungen zur Bioindikation
Flora, 1982Summary The dates of on experimental study on bioindication in a spruce forest are used to estimate the metric relations of net primary production and shoot length of higher plants. It is pointed out, that the functions correspond to allometric regularity (y = a · x b ). The functions are changed by strong environmental disturbances.

Löwenzahn Taraxacum officinale Web. als (städtischer) Bioindikator
Umweltwissenschaften und Schadstoff-Forschung, 2000Untersuchungen von Lowenzahn Taraxacum officinale Web. in Polen, Rumanien und Deutschland haben gezeigt, dass diese Art in immionsbelasteten Gebieten verschiedene Elemente in Abhangigkeit von der Immissionsintensitat anreichern kann. In dieser Arbeit wird nun der Frage nachgegangen, ob Taraxacum officinale die Elemente uber die Blatter aus der ...

Med kao bioindikator kontaminacije okoliša cezijem
2005Sakupljajući nektar i polen, pčele pokrivaju područje površine dvadesetak km2. Med u košnici predstavlja kompozitni uzorak sakupljen sa nekoliko stotina milijuna točaka i vjerojatno je jedan od najreprezentativnijih slučajnih uzoraka koje je uopće u okolišu moguće prikupiti.

Borove iglice - bioindikator onečišćenja zraka
2005Ispitane su i uspoređene razine šest indikatorskih kongenera PCB-a i sedam organoklorovih pesticida u zraku sakupljenom od 1999. do 2001. godine i u borovim iglicama sakupljenim u 14 urbanih mjesta u Hrvatskoj. Iz prikazanih rezultata vidljivo je da se onečišćenje zraka odražava na onečišćenje borovih iglica na taj način da su isti spojevi prisutni u ...
