Recent reports have shown an increase in potentially harmful phytoplankton in Santos bay (Southeastern Brazilian Coast), located in a highly urbanised estuarine complex. Prediction of blooms is, thus, essential but the phytoplankton community structure in very dynamic regions is difficult to determine. In the present work, we discriminate bloom forming microphytoplankton dominance and their relationship to physical and meteorological variables to look for patterns observed in different tides and seasons. Comparing 8 distinct situations, we found five scenarios of dominance that could be related to winds, tides and rainfall: i) Surfers, diatoms occurring during high surf zone energies; ii) Sinkers, represented by larger celled diatoms during spring tide, after periods of high precipitation rates; iii) Opportunistic mixers, composed of chain forming diatoms with small or elongate cells occurring during neap tides; iv) Local mixers, microplanktonic diatoms and dinoflagellates which occurred throughout the 298 sampling stations; and v) Mixotrophic dinoflagellates, after intense estuarine discharges. Results suggest alterations in the temporal patterns for some bloom-forming species, while others appeared in abundances above safe limits for public health. This approach can also illustrate possible impacts of changes in freshwater discharge in highly urbanised estuaries.

Achados de 26 casos da literatura, somados aos 3 casos aqui descritos, sugerem que cerca de um terco dos pacientes com ataxia telangiectasia tem glicemia de jejum normal com hiperglicemias apos a ingestao oral de glicose. Estes achados enquadram-se nos criterios para tolerancia a glicose diminuida do assim chamado diabetes quimico. O diabetes do tipo II estava presente em apenas um dos 29 pacientes e nenhum deles tinha a deficiencia total de insulina que se encontra no diabetes tipo I. Entao, as hiperglicemias da ataxia telangiectasia representam apenas tolerancia diminuida a glicose e sao claramente distintas do diabetes, seja tipo I ou II. A frequente hiperinsulinemia basal ou apos sobrecarga de glicose de ataxia telangiectasia, com ou sem hiperglicemias, e compativel com a hipotese de bloqueio ou diminuicao de numero de receptores para insulina
