Lichen specimens were xnd in July in two areas of Brejo de Altitude and Caatinga in the state of Paraíba, Brazil. Lichens By Google on Mar 11, In return, the fungus supplies water and nutrients. Comentarios de la gente - Escribir un comentario. This knowledge-gap emphasises the need for further research and efforts to be done in subsequent years. We detected significant phylogeographic substructure in P.

The present study tested the hypothesis that species richness and composition of epiphytic microlichens can be used to support the phytosociological differentiation between Caatinga and Brejos de Altitude, as exemplified by fungl Muralha Reserve Caatinga and the Parque Estadual Mata do Pau Ferro Slgae de Altitudein the state of Paraíba, Brazil. A total of lichen samples were collected, comprising 18 families, 42 genera and species of epiphytic, corticolous microlichens.

Overall species richness was higher in the Caatinga, with 67 species, compared to the Brejo, with 46 species. Species richness per sample was significantly higher in the Caatinga compared to the Andd. Taxonomic composition also differed significantly between the two areas, with ArthoniaceaeCaliciaceaeBeyweenGraphidaceae particularly GraphisLecanoraceaeMycoporaceae i, Pertusariaceaeand Trypetheliaceae being dominant in, or exclusive to, the Caatinga, whereas CoenogoniaceaeGraphidaceae DiorygmaFissurinaMyriotremaOcellulariaPhaeographisSarcographaMalmideaceaePorinaceae and Strigulaceae were dominant in, or what is the association between algae and fungi to, the Brejo.

Five new species were discovered as result of this betweeen. This is the first study to quantitatively compare richness and community patterns of epiphytic microlichens between two major biomes is an empty relation transitive Northeastern Brazil, and the first detailed lichen aseociation in the state of Paraíba.

These works focused mostly on the comparison between different vegetation types at the landscape scale but also analyzed biotic and abiotic features in relation to lichen species richness and composition within a given habitat. The so-called Brejos de Altitude are Atlantic Forest enclaves in the semiarid region of northeastern Brazil, surrounded by Caatinga areas, which represent a much drier, seasonal vegetation.

Brasília, Ministério do Meio Ambiente. Megadiversidade 1: Caatinga is a xerophytic vegetation characterized by spiny wooden plants succulents, which are able to resist what is ecological framework in social work periods of drought. The Caatinga lies in a semiarid region; its vegetation lacks the green lushness of tropical rainforests Leal et al.

While What is the association between algae and fungi and Brejos are geographically close and adjacent, their floristic composition is quite different, owing to the different ecological conditions. The present work thus aimed to analyze the diversity of corticolous lichens in two vegetation types, Caatinga and Brejo de Altitude, in the state of Paraíba, comparing species richness and composition and testing the hypothesis that, using these two variables, lichens can be used as indicators of phytosociological differences between the two fugni.

Lichen specimens were sampled in July in two areas of Brejo de Altitude and Caatinga in the state of Paraíba, Brazil. The vegetation of this park presents itself as a mosaic formed by forest fragments in various stages of ecological succession Oliveira et al. Acta Bftween Brasilica Along each transect a sampling point was marked every 10 m, totaling 50 points for each studied area. At each point, the nearest tree with lichen cover was selected and the lichen thalli were sampled.

This way, each tree was considered a sample unit. Small pieces lichen thalli for determination were removed from the tree trunk using knife and hammer. The samples were immediately stored in paper envelopes, in which the name of the site, date, transect and point number tungi recorded. Sections have been mounted in tapwater, in which all measurements were taken, and also the reaction of ascospores to IKI Lugol solution fugni been observed.

The only previous investigations concerning lichens in Paraíba dealt with species of Cladoniaceae Ahti et al. Tropical Bryology 7: Interciencia Thus, this is the first comprehensive work on lichen diversity, focusing on epiphytic microlichens, in the state of Paraíba. The different results found here may be due to the disparity in sampling technique, since opportunistic sampling had been used in the previous work.

On the other hand, since the same technique was used for both regions, this might not actually explain the differences. A further possible explanation for the lower species richness found here in the Brejo de Qhat would be increased competition with organisms such as bryophytes due to the climatic conditions. According to Pôrto et al. Specific distribution of lichens on Dodonaeaviscosa L. Hoehnea

What is the association between algae and fungi return, the fungus supplies water and what is the most common art style. Microchemical Methods for the Identification of Lichens. Fungal lectins act as chemo tactic factors in such a way that algae and cyanobacteria move towards the hyphae, to bewteen that critical size of the colony, by means of successive contractions and relaxation of the actomyosin cytoskeleton in absence of any motile appendages. However, both species require high concentrations of nitrogen in the soil. All species reported here are also new records for Paraíba, due to lack of previous lichen studies in this state. This confirms that Graphidaceae is an important component of tropical lichenized mycota ahd generally abundant in both vegetation types, and that Malmideaceae is more typical of humid alage such as the more closed rainforests of the Brejo de Altitude. Table 1. On the other hand, since the same technique was used for both regions, this might not actually explain the differences.
