Previous issue date: 2013-03-14 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / This study aimed at surveying the coccoid green algae flora of two areas of the Pantanal
dos Marimbus (Baiano and Remanso), EPA Marimbus Iraquara, located in the Chapada
Diamantina, Bahia, Brazil. Material was obtained from 120 samples collected during the dry (April, June and August 2011) and in the rainy season (October and December 2011, and February 2012). During this study 121 taxa of coccoid green algae were identified, described, illustrated and commented, which are distributed in two classes, four orders and 46 genera, 109 species, three varieties typical and seven other does not typical of their respective species, and two taxonomic formae. 17 (14%) of the total of taxa identified are pioneer citations for Brazil, 51 taxa (42%) for the Northeast Region of Brazil, and 19 taxa (15,7%) for the Bahia State. Most taxa recorded were classified in the Sphaeropleales (76%), followed by Chlorellales (17%), Trebouxiales (3%) and Chlorococcales ?sensu stricto? (2%), while the taxa considered ?incertaesedis? were represented by 3% of the total taxa identified. Among the taxa studied in both areas, 14 were exclusive of the rainy period and only seven of the dry one, while 100 taxa were common to both climatic periods. The species richness was clearly higher in the Marimbus do Baiano with 115 taxa (95%), while the Marimbus do Remanso showed 99 taxa (82.5%). Of the 121 taxa studied, 22 were unique to the Marimbus do Baiano and six to the Marimbus do Remanso. According to the S?rensen similarity index (86.9%), the similarity between the Marimbus do Baiano and do Remanso was considered high. Most taxa inventoried (48%) was classified as rare on Pantanal Marimbus, followed by infrequent (42%), frequent (7%) and very frequent (3%). Considering that about 90% of the taxa found are listed first for the Bahia State, we strongly suggest continuing studies of biodiversity of inland water algae to increase knowledge of phycoflora in Bahia State and Brazil. / O presente estudo ? o levantamento flor?stico das algas verdes coc?ides ocorrentes em
duas ?reas do Pantanal dos Marimbus (Baiano e Remanso), APA Marimbus Iraquara, localizada
na Chapada Diamantina, Bahia, Brasil. Os materiais estudados provieram de 120 amostras
coletadas no per?odo seco (abril, junho e agosto de 2011) e no chuvoso (outubro e dezembro de
2011 e fevereiro de 2012). Foram identificados, descritos, ilustrados e comentados 121 t?xons
de algas verdes coc?ides, distribu?dos em duas classes, quatro ordens e 46 g?neros, 109
esp?cies, tr?s variedades t?picas e sete n?o t?picas de suas respectivas esp?cies e duas formas
taxon?micas. Do total de t?xons inventariados, 17 t?xons (14%) s?o cita??es pioneiras para o
Brasil, 51 t?xons (42%) para a Regi?o Nordeste do Brasil e 19 t?xons (15,7%) para o Estado da
Bahia. A maior riqueza de t?xons foi registrada para a ordem Sphaeropleales (76%), seguida de
Chlorellales (17%), Trebouxiales (3%) e Chlorococcales ?sensu strictu? (2%), enquanto que os
t?xons considerados ?incertae sedis? foram representados por 3% do total. Dentre os t?xons
estudados nas duas ?reas, 14 foram exclusivos do per?odo de chuva e apenas sete do per?odo de
seca, enquanto que 100 t?xons foram comuns a ambos os per?odos clim?ticos. A riqueza
espec?fica foi claramente maior no Marimbus do Baiano, com 115 t?xons (95%), enquanto que
o Marimbus do Remanso apresentou 99 t?xons (82,5%). Dos 121 t?xons inventariados, 22
t?xons foram exclusivos do Marimbus do Baiano e seis do Marimbus do Remanso. De acordo
com o ?ndice de Similaridade de S?rensen (86,9%), a similaridade entre os Marimbus do Baiano
e do Remanso foi elevada. A maior parte dos t?xons inventariados (48%) foi classificada como
de ocorr?ncia rara no Pantanal dos Marimbus, seguido de pouco frequente (42%), frequente
(7%) e muito frequente (3%). Considerando que cerca de 90% dos t?xons encontrados s?o
referidos pela primeira vez para o Estado da Bahia, sugere-se a continuidade dos estudos de
biodiversidade de algas de ?guas continentais para ampliar o conhecimento da ficofl?rula na
Bahia e no Brasil.
