Algae in phytotelmata from Caatinga: first record of the genus Rhopalosolen Fott (Chlorophyta) for Brazil

Abstract: The first record of the genus Rhopalosolen Fott (Chlorophyta) for Brazil is presented here. Taxonomic studies on phytotelm algae are, in general, scarce, but especially are so in semi-arid regions such as the Caatinga. Here, we sampled 60 bromeliads in the Itaberaba's municipality, Bahia state, and we identified Rhopalosolen cylindricus, a green algae species not previously recorded for Brazil. Additionally, our data provide an expansion on the known distribution of the species and their morphological and repr… Show more

“…In terms of the main Chlorophyta taxa, we highlight the genus Rhopalosolen, which was recently reported for the first time for Brazil (Ramos et al 2017c). In the bromeliads with a predominance of filamentous green algae (such as the genus Oedogonium), common predators such as rotifers, cladocerans, and copepods could be influencing the low observed algal richness.…”

“…In contrast to most live substrates (average pH = 4.35), dead phytotelmata are usually in canopy gaps, where rain falls directly into the pools. When reported, the pH of most phytotelmata is acidic (Kitching 2001, von May et al 2009, Poelman et al 2013, Ramos et al 2017); but see Lehtinen 2004, which shows that Pandus bromeliads were close to neutral pH). However, most studies on phytotelmata are biased towards living plants and trees, and assess chemical/biological variables of pools at a single time point.…”

“…No Brasil, a maioria dos trabalhos sobre comunidades fitotelmatas estão direcionados ao estudo da fauna, principalmente de invertebrados (Mestre et al 2001, Juncá & Borges 2002, Araújo et al 2007). Com relação à ficoflórula, destaca-se os trabalhos de ambiente fitotelmata bromelícola realizados por Lyra (1971Lyra ( , 1976) com diatomáceas nos estados do Rio de Janeiro e Pernambuco, respectivamente; Sophia (1999) e Sophia et al ( 2004) com desmídias no Rio de Janeiro; e os desenvolvidos na Bahia por Ramos e colaboradores com euglenofíceas (Ramos et al 2017a), desmídias (Ramos et al 2011(Ramos et al , 2017b(Ramos et al , 2017c(Ramos et al , 2018a, dinoflagelado (Ramos et al 2016) e clorofíceas (Ramos et al 2017d, Ramos et al 2018b.…”

“…O arranjo das folhas das bromélias em roseta, formando imbricamentos, permite que a água das chuvas, quando precipitada, fique retida nas folhas centrais e laterais formando pequenos tanques, ondem podem ocorrer algas, protistas, invertebrados e vertebrados (Picado 1913;Dias & Brescovit 2004;Maguire 1971).No Brasil, a maioria dos trabalhos sobre comunidades fitotelmatas estão direcionados ao estudo da fauna, principalmente de invertebrados (Mestre et al 2001, Juncá & Borges 2002, Araújo et al 2007). Com relação à ficoflórula, destaca-se os trabalhos de ambiente fitotelmata bromelícola realizados por Lyra (1971Lyra ( , 1976) com diatomáceas nos estados do Rio de Janeiro e Pernambuco, respectivamente; Sophia (1999) e Sophia et al ( 2004) com desmídias no Rio de Janeiro; e os desenvolvidos na Bahia por Ramos e colaboradores com euglenofíceas (Ramos et al 2017a), desmídias (Ramos et al 2011(Ramos et al , 2017b(Ramos et al , 2017c(Ramos et al , 2018a, dinoflagelado (Ramos et al 2016) e clorofíceas (Ramos et al 2017d, Ramos et al 2018b.Baseado nos trabalhos acima acredita-se que exista uma biodiversidade ficológica particularmente interessante a ser descoberta nesses ambientes. Assim, estudos de inventário taxonômico são necessários visando ampliar o conhecimento sobre a biodiversidade das clorofíceas de ambiente fitotelmata bromelícola na Bahia e, consequentemente, no Brasil.…”
