“…Gaertn., in the states of Amapá, Pará, Pernambuco and Sergipe. Trierveiler-Pereira et al (2008) Studies initiated in 2007 in the Rio Formoso municipality on the southern coast of Pernambuco resulted in the registration of 23 species and 14 genera associated with trees and shrubs typical of mangrove, including some not previously recorded in the Neotropics or in the mangrove environment (Damasceno et al 2011(Damasceno et al , 2009. Continuing these studies, we present new records of myxomycetes on Avicennia nitida Jacq., L. racemosa and R. mangle microhabitats, thereby contributing to the increase in knowledge of myxomycetes present in ecosystems associated with the Atlantic Forest, particularly corticolous species and those found in aerial litter.…”

Background: Mangroves are distributed among tropical and subtropical coastlines of all oceans, and associated macroflora and macrofauna are generally well studied. However, information on mangrove-associated microbiota is still scarce. To help fill this gap in knowledge, we conducted research on the occurrence of Myxomycetes in the southern coast of Pernambuco state, northeastern Brazil. In the Rio Formoso estuary, we examined adult Rhizophora mangle (Rm), Laguncularia racemosa (Lr) and Avicennia nitida (An), collecting samples of live trunk bark (Bk), twigs from aerial litter (Tg), and aerial leaf litter (Lf) for moist chamber culture (n = 600). Results: The following species were identified: Arcyria cinerea (Rm/Tg); A. pomiformis (Rm;Lr/Bk); Collaria arcyrionema (Rm/B); Clastoderma debaryanum (Lr/Bk; Rm/Tg); Cribraria violacea (Rm/Bk;Tg); Physarum auriscalpium (Rm/Tg); P. tenerum (Rm/Bk); Stemonitis fusca (Lr/Tg); S. herbatica (Rm/Lf); S. virginiensis (Rm/Tg) and Stemonaria irregularis (An/Lf). The percentage of positive cultures was very low (24 %), with Rm as the predominant substrate with eight species and Tg as the predominant microhabitat. The majority of species are rare (60 %) and Physarum auriscalpium was the only species frequently registered. The taxonomic diversity indices ranged from 1.00 (Lf;Bk) to 1.20 (Tg). Conclusions: There was no similarity in the composition of myxobiota found on the substrates and microhabitats analyzed. Only S. irregularis was found in mangroves that inhabit areas of higher salinity. Physarum tenerum is reported here for the first time in the mangrove environment.

Myxomycetes from mangroves: species occurring in the state of Maranhão, northeastern Brazil

2015

Mangrove swamps and forests cover over 137,000 km 2 distributed latitudinally among subtropical zones, 7% of which are in Brazil, with a greater density in the country's northernmost region. Considering that the community of Myxomycetes recorded for this environment is hardly known, three areas located in the state of Maranhão were investigated. Two field trips were conducted, one at the beginning of the rainy season and another during the dry season. In each area, two plots (125 m 2 ) equidistant 100 m apart from each other were surveyed. In these areas, standing dead tree trunks and dead branches still attached to the mother plant that were above the tideline, were examined. On these same occasions, samples of the aerial litter and from the cortex of living trees (Rhizophora) were collected for the preparation of moist chambers cultures. Twenty-one specimens were obtained from field and moist chambers, belonging to 11 species, distributed in nine genera and five families. Seven species are new records from Maranhão. There was a predominance of r-strategist (73%) over K-strategist (27%) species. Cribraria violacea, Comatricha tenerrima, Echinostelium minutum, and Fuligo septica are new worldwide records from mangrove environments, and Oligonema flavidum is reported for the first time from Brazil.Keywords: Myxobiota, mangrove swamps, Oligonema, Rhizophora, microhabitat. Myxomycetes em manguezais: espécies ocorrentes no estado do Maranhão, nordeste do Brasil ResumoOs manguezais ocupam mais de 137.000 km 2 , distribuídos latitudinalmente entre as zonas subtropicais e 7% encontra-se no Brasil, com maior densidade entre os estados do Pará e Maranhão, na região norte do país. Considerando que a comunidade de mixomicetos registrada para este ambiente é pouco conhecida, três áreas localizadas no estado do Maranhão foram investigadas. Duas excursões foram realizadas, uma no início da estação chuvosa e outra na estiagem. Em cada área, foram georeferenciadas e exploradas duas parcelas (125 m 2 ) equidistantes 100 m uma da outra foram avaliadas. Nestas, foram explorados troncos mortos em pé e galhos mortos ainda presos à planta-mãe, acima da linha da maré. Nas mesmas ocasiões foram coletadas amostras de folhedo aéreo e córtex de árvores vivas (Rhizophora) para montagem de câmaras-úmidas. Foram obtidos 21 espécimes de campo e câmara-úmida, pertencentes a 11 espécies, distribuídas em nove gêneros e cinco famílias. Sete espécies são novos registros para o Maranhão. Predominaram espécies r-estrategistas (73%), e 27% K-estrategistas. Cribraria violacea, Comatricha tenerrima, Echinostelium minutum e Fuligo septica são novos registros para o ambiente de manguezal, e Oligonema flavidum é registrada pela primeira vez no Brasil.
