August of to July of and August of to May of Combining culture methods and baiting techniques, it was possible to verify the presence of terrestrial fungi on the decomposition of submerged leaves and the importance of zoosporic fungi in the fungal succession. Part I-Tropical American Species. The usually diversified and competitive mycota present in the leaf tissues, before submergence, may include “autochthonous” fungi, that resist to drastic environmental changes and participate on further decomposition processes, until some of the native aquatic fungi are able to colonize and dominate the substrate Park According to Newtonas soon as the leaves are submerged in the water, many alcgornea of aquatic Hyphomycetes are “attracted” to the substrate, taking their place as initial decomposers.

The most common genera were Fusarium 11 registersTrichoderma 6Penicillium 5Cladosporium 4 and Mucor 4.

This is the first paper about the fungal succession on the decomposition of leaves submerged in a lotic ecosystem in Brazil. Although the aquatic Hyphomycetes, as well as some zoosporic fungi may be considered initial decomposers, with high capacity to degrade cellulose and lignin compounds Willoughbytheir presence in the leaves of A.

The number of fungal species and alcohrnea total number of registers increased in function of the time of decomposition of the leaves.

Once again, the dominance of terrestrial fungi on the submerged substrate may justify these results. Euphorbiaceae is a tree which occurs in a broad range of habitats in Brazil. Illuminating the systematics of the Spiranthes sinensis species complex Orchidaceae: A quantitative approach was used to examine the role of light and soil water regime on the variations found in anatomical traits of the palisade and spongy parenchyma, outer epidermal cell wall of the abaxial and adaxial surfaces, the percentage of sclerenchymatous area in relation to the total midrib area and the ratio of palisade to spongy parenchyma for five distinct ecological populations: Color The sapwood is not differentiated.

Tukey tests were carried out for multiple comparisons, while one-way factor variance analysis was used to test for differences among ecological populations.

This species is dioecious, meaning that it has male and female individuals. Key words – Fungal succession, leaf decomposition, Atlantic Rainforest, aquatic system. In The fungal community: Zoosporic fungi and aquatic Hyphomycetes showed a tendency to occur in an intermediate phases of the succession.

Trichoderma viride 23Fusarium oxysporum 23 and Penicillium hirsutum It is a dominant tree, it attains heights from 15 to 30 m. Machining This species is easy to machine.

Resistance To Impregnation B. Natural Habitat Alchornea triplinervia is found in rain forests from the sea level alhcornea until 1, m of altitude, it is also found in the Atlantic rain forest.

Tropicos | Name – Alchornea triplinervia (Spreng.) Müll. Arg.

The first papers about fungal succession on submerged leaves in Brazil were concerned with the decomposition of Ficus microcarpa L. Close mobile search navigation Article navigation.

Occurrence of filamentous fungi on decaying leaves in lake waters Albano and Nemi, central Italy. From the eighth and ninth months on, Catenophlyctis variabilisFusarium lateritium, Mucor hiemalis f.

Fibers with distinctly bordered pits. Pollination of an endangered Caladenia species Orchidaceae by nectar-foraging behaviour of a widespread species of colletid bee. Fungi were isolated by the leaf disks washing technique followed by plating on culture media and also by using baiting alchodnea using substrates with chitin, keratin and cellulosewhat resulted on fungal aochornea corresponding to 81 taxa.

Forty litter bags were submerged at each of five collection points along the stream. Soil fungi and fertility.

The failure of many species to grow on culture media and the necessity to use baiting techniques to detect their presence on the substrates, make the study of the activity of zoosporic fungi very difficult, justifying their absence in the studies mentioned above. Regulation of leaf breakdown by fungi in streams: Aquatic Hyphomycetes on oak leaves: Considering the high diversity of the terrestrial fungi usually found in submerged substrates, the role of “geofungi” and of the zoosporic fungi that do not produce ergosterol in the decomposition of submerged substrates have to be stressed out in further studies.

The colonies of Deuteromycotina, Zygomycotina and Ascomycotina that grew around the leaf disks were isolated after seven days of incubation o Cwhile the zoosporic fungi were observed after five days of incubation.

Fungi were isolated by the leaf disk washing technique Pugh et al. In July of and recently fallen leaves of A.
