Geographical distribution of exotic dinoflagellate of freshwater Ceratium furcoides (Levander) Langhans 1925 in Brazil

Abstract

Biological invasions are becoming serious environmental problems. In several records, they cause irreparable damage to biodiversity. This job is about a short review on the current state of expansion of the species Ceratium furcoides (Levander) Langhans 1925 in Brazil, based on what has already been published. The species has now been recorded in several rivers and reservoirs from at least six of the 26 states. The occurrence of high densities in Brazil is always linked to high temperatures, which is an aggravating factor for our country. Effective limnological monitoring is needed to identify and seek measures to address such problems as soon as possible, as well as correlations studies of cellular densities of C. furcoides with abitotic parameters such as temperature, pH, salinity, levels of nitrogen compounds and phosphates.
