GLOBAL DISTRIBUTION AND FIRST RECORD OF THE INVASIVE SPECIES Kellicottia bostoniensis (ROTIFERA: BRACHIONIDAE) IN TWO BRAZILIAN RESERVOIRS A

Resumo

Aquatic ecosystems are subject to biological invasions causing imbalance mainly in the native populations. In most freshwater environments rotifers are abundant and highly adapted. The North American rotifer Kellicottia bostoniensis (Rousselet 1908) is widely distributed in Asia, Europe, Central and South America inhabiting reservoirs, lakes and rivers of these continents. Here, the occurrence of K. bostoniensis is recorded for the first time in Atibainha and Cachoeira reservoirs (Brazil). Dispersal devices are provided and this note extends the limit distribution of K. bostoniensis in São Paulo state.
