Fungal succession on plant debris in three humid forests enclaves in the Caatinga biome of Brazil

Background and aims – A study of richness and diversity of conidial fungi associated with plant debris was conducted in three Atlantic Forest enclaves in the Caatinga biome: Serra da Jibóia-BA (SJ), Serra da Ibiapaba-CE (SI) and Brejo Paraibano-PB (BP). Methods – The plant debris samples included leaves, twigs and barks and were washed in running water, incubated in moist chambers and analyzed for 40 days under a stereomicroscope. These reproductive structures were transferred to slides containing PVL resin and identified with specialized literature. Key results – The richness and diversity were similar in the three enclaves of interest. Cluster analysis using the Morisita similarity index indicated a group formed by fungal communities of SI and BP and another with SJ. Of these substrates, the leaves had the greatest richness and the bark samples had the greatest diversity, but these differences were not significant. Multivariate analysis via NMDS revealed differences in the fungal community composition with respect to the substrate and area, but the similarity analysis (ANOSIM) indicated that the differences were significant only with respect to the substrate.Conclusions – The survey data shows the great richness and diversity of conidial fungi in the studied areas. Substrate was the most determinant factor for the distribution of fungi when compared with area.

First Time

Abstract Species of the Beltrania group are constantly identified in association with a variety of plant debris in Brazil and different localities of the world. Leaf litter samples of Myrcia splendens and Pera glabrata were collected in the Reserva Biológica de Una, municipality of Una, Bahia state, Brazil, in August 2012, and incubated in moist chambers. Two specimens related to Beltrania group were isolated and identified by morphological criteria. This study aimed to describe and illustrate Beltraniopsis rhombispora for the first time in Brazil. Hemibeltrania decorosa previously reported from Caatinga Biome, Bahia state, has been cited for the first time for Atlantic Forest.

AbstractThe Lower Carboniferous, probably Tournaisian, Kweekvlei Formation is part of the Witteberg Group (Cape Supergroup) of South Africa. Together with the overlying Floriskraal Formation, it forms an upward-coarsening succession within the Lake Mentz Subgroup. Sedimentary features of the Kweekvlei Formation suggest deposition in a storm-wave dominated marine setting, within the storm-influenced, distal part of an offshore transition zone environment. This predominantly argillaceous formation preserves a low diversity trace fossil assemblage. Reworked vascular plant debris (including the problematic genus Praeramunculus sp.) and a shark spine have been reported for the Kweekvlei Formation. There are no known stratigraphic equivalents in South Africa.

Abstract Sediment from a wetland receiving runoff from a coal mine waste dump in the Elk River Valley of southeast British Columbia was assessed for potential selenium uptake. Selenite [SeO32-, Se(IV)] was found to adsorb to the washed sediment at pH 7 to 8, whereas no selenate [SeO42-, Se(VI)] was adsorbed, in the concentration range of 8 to 225 μg L-1 Se as selenite or selenate. Sulfate- and selenate-reducing bacterial activity was detected in the sediment. In the presence of sulfate-reducing bacteria growth medium, Se as selenate was reduced from 619(±53) μg L-1 to 15(±0.7) μg L-1, and in the presence of selenate-reducing bacteria growth medium, Se as selenate was reduced from 364(±66) mg L-1 to 22(±10) mg L-1. Semi-continuous microcosms containing sediment overlaid with selenate (500 μg L-1 Se) and sulfate (0.9 g L-1) containing water were amended with plant debris from the site or nutrients (lactate and fertilizer). Potential selenate reduction rate (0.76 h-1) was highest in the unamended microcosms. Amendment with plant debris from the site had a negative effect on selenate reduction rate in the short term (after one hour) and a positive effect on Se removal in the long term (after one week). This study suggests that wetland sediments at the mine site may be important sinks for Se.
