Knowledge on biodiversity is fundamental for conservation strategies. The Brazilian Pampa region, located in subtropical southern Brazil, neglected terms of conservation, and knowledge its fragmented. We aim to answer the question: how many, which, species occur Pampa? In a collaborative effort, we built lists plants, animals, bacteria, fungi that Pampa. included information distribution patterns, main habitat types, status. Our study resulted referenced totaling 12,503 (12,854 taxa, when...
Background and aims – The corticolous microlichens are the greatest group of lichens in world also least known. For this reason intensive studies on seriously needed. Based necessity, main objective paper is to present new records microlichen species for South America, Brazil, Southern region Brazil state Rio Grande do Sul. Methods were collected three different forest types: native Araucaria forest, Atlantic rainforest riparian forests from Pampa Biome. Key results A total 43 here...
Os liquens são reconhecidos por serem muito sensíveis à poluição atmosférica, sendo assim sua utilização como indicadores biológicos da qualidade ambiental, tem sido um procedimento cada vez mais amplo. Este trabalho apresenta os resultados do monitoramento passivo realizado na área de abrangência uma usina termoelétrica, região sul Brasil. foram avaliados em cinco pontos onde foi amostrado total 50 forófitos. Foram registrados 45 táxons, destes citados literatura bioindicadores ar. As áreas...
Lichenized fungi are epiphytic components of forest areas where anthropogenic activities may cause changes in species composition and spatial distribution. The aim this work is to evaluate how the lichen community distributed on native planted vegetation, also investigate possible preferences for specific host trees related bark pH values. A total 120 host-trees 12 remnants vegetation were analyzed: Araucaria Araucaria, pine eucalyptus plantations. Additional samples lichenized collected all...
Environmental Protection Areas (EPA) are of extreme importance for species conservation and establishment.We investigated different areas riparian forests in the Area Ibirapuitã, southern Brazil.We analyzed environmental quality these by studying lichen community using index atmospheric purity (IAP) with classification factor (ECF) as correction factor.The was 12 forest stands located region EPA.Lichens were registered on 60 tree barks, from 50 cm to 150 above ground, both north south...
Based on the need to monitor air pollution and importance of doing it with biological organisms, present work had as main objective assess quality in urban areas through lichen transplants. Besides, we also tested whether there were differences among studied sites, aiming point out characteristics areas. The monitoring was carried seven cities, which varied from mainly rural industrial, Rio Grande do Sul, southern Brazil. foliose Parmotrema tinctorum used biomonitor species. Physiological...
Abstract A world key to the 21 species of Stirtonia is presented. Three new are described from Neotropics: ibirapuitensis Aptroot, Käffer & S. M. Martins, with whitish cream amoeboid ascigerous areas lichexanthone on a greenish thallus without and ascospores 27–32×9·5–12·5 µm; punctiformis Aptroot Sipman, structures colour, consisting one or more brown asci walls surrounding tissue, in groups irregular lines 61–73×27–35 viridis L. I. Ferraro, Sipman Cáceres, mostly linear, branched...
São apresentadas 26 novas espécies de liquens crostosos para o Brasil e Estado do Rio Grande Sul, sendo três destas ocorrências também 23 novos registros Estado. Os foram analisados em 300 forófitos distribuídos 32 bairros da cidade Porto Alegre na área Parque Estadual Itapuã, Viamão, RS.
Liquens são organismos em simbiose que habitam os mais diversos ambientes, entretanto regiões urbanizadas a comunidade liquênica pode ser modificada devido à influência de fatores antrópicos. O objetivo deste trabalho é analisar composição da corticícola na cidade Porto Alegre e áreas adjacentes, assim como verificar freqüência, cobertura valor importância dos táxons, apresentando uma chave identificação para as espécies urbanas. Foram analisadas 300 forófitas distribuídas 30 estações...
São apresentados resultados de levantamento baseado em dados coletas fungos liquenizados algumas localidades Mata Atlântica na região sul do Brasil. Foram identificados 88 táxons distribuídos 18 famílias e 36 gêneros; destes, dois são citações novas para o Brasil um é nova ocorrência Rio Grande Sul.
The hairs of Leptogium species are complex structures which determine taxonomic groups within the section Mallotium. composed cylindrical cells can be short and, when present on surface, give origin to glass-or velvet-like hairs. involutum, collected in Southern Brazil, a new with is described herewith.
Background and objectives – Changes in forest landscapes management practices strongly influence biodiversity. The main objective of this study is to evaluate the lichen community structure considering species diversity parameters, such as: richness, cover, average thallus size, at different stands Environmental Protection Area (EPA) Ibirapuitã, Brazil.Methods lichens were analyzed relation their position on tree trunks possible correlation with some environmental factors was studied. data...
São apresentados os resultados do levantamento dos fungos liquenizados em algumas localidades situadas na área das sub-bacia Sinos e Taquari-Antas, realizado no ano de 1997. Foram identificados 76 táxons distribuídos 21 famílias 40 gêneros.
Riparian forests are among the most threatened ecosystems and their conservation essential for preservation of biological communities. The main objective this study was to analyze environmental quality riparian forest sites inserted in three matrices (rural, urban, industrial) by using structural parameters functional traits lichen community. Lichens were sampled seven areas, along Hydrographic Basin Sinos River (HBSR), acetate method. Structural analyzed all as well secondary metabolites...
The new lichen species Graphis obtectostriata is described from Rio Grande do Sul in southern Brazil. It characterized by lirellae that are almost totally covered thallus, but striate underneath, and long, transversely septate ascospores. All so far known with similar ascomata, the so-called consanguinea-morph, have muriform
RESUMO Os liquens fazem parte de um grupo extremamente diverso e são componentes importantes em áreas florestais. O objetivo deste trabalho foi analisar a composição da comunidade liquênica verificar os padrões fitossociológicos táxons ocorrentes florestais ribeirinhas, na APA do Ibirapuitã, RS, Brasil. mapeamento dos realizado através método acetato, 60 forófitos (palavra masculina que designa árvores servem suporte para epífitas) distribuídos 12 Foram registrados 254 liquênicos, destes 199...
Abstract The riparian forest sustains an expressive richness and diversity of species anthropogenic impacts in certain sites have caused changes the structure communities. This study aimed to analyze composition structural parameters lichen community forests. was carried out seven surrounded by different matrices: rural, urban industrial. lichens were mapped using acetate method phytosociological analyzed. A total 208 identified. rural matrix differed from others dominance morphological...
