First data on lichens of the Teteriv River Basin appeared in the second part of 19th century. First records of lichenicolous fungi in this area were published at the end of the 20th century. An annotated list of lichens ...

Hydrocarbon pollution from oil spills, traffic emissions, and industrial processes continues to be a significant global threat to biodiversity, soil quality, water quality, and human health. Lichens, mutualistic life for...

Abstract Mosses and lichens are effective bioindicators because they absorb nutrients and pollutants directly from the atmosphere, allowing them to accumulate metals and nutrients. This study evaluated mosses and lichens...

Lichens represent one of the most successful examples of symbiosis. They are constituted by the association between a dominant fungus (i.e., the mycobiont), one or more photosynthetic partners (algae or cyanobacteria), a...

This paper reports on the April-May 1983 Projeto Flora expedition to Serra do cachimbo in northcentral Brazil, a phytogeographically poorly known area near the transition between the Amazon forest and the central Brazili...

Antarctica presents one of the most severe environmental conditions for life. Under these circumstances, cryptogams are the dominant photosynthetic organisms, among which we find a great richness of lichens. In Antarctic...

ABSTRACT Thrombosis is a pathophysiological disorder caused by accumulation of fibrin in the blood. Fibrinolytic proteases with potent thrombolytic activity have been produced by diverse microbial sources. Considering th...

The results of the specific distribution of lichens sampled on 30 small Dodonaea viscosa L. trees located in a restinga area on the banks of Lagoa Negra in Itapuã State Park, Rio Grande do Sul, State are presented. The ...

ABSTRACT While lichens are vital for ecosystem processes and serve as useful bioindicators, lichen diversity remains understudied, particularly in southern Ecuador. Here, we report the first inventory of corticolous (on ...

Foi estimada a biomassa (viva + morta) acima do solo de um ecossistema de "campina" localizado em Roraima, norte da Amazônia brasileira. A biomassa foi determinada a partir de um inventário fitossociológico (1 ha amos...

Los líquenes representan una forma de vida compleja caracterizada por una asociación simbiótica entre al menos dos organismos: un hongo y un alga. En esta relación única, el hongo ofrece un hábitat protector para e...

ABSTRACT The study of lichens in Neotropical regions has uncovered a remarkable diversity, much of which remains largely unexplored. Within this context, several species of Sarcographa, including the common and widesprea...

El decaimiento forestal está frecuentemente asociado a la mortalidad parcial o total de las copas en un alto porcentaje de individuos de un rodal. Si bien el decaimiento ha sido documentado a escala global, las relacion...

A survey of the parmotremoid lichens occurring in the central area of Rio Grande do Sul State (Brazil) revealed 31 species of Parmotrema A. Massal., distributed in three groups corresponding to the former genera Canomacu...

IntroductionLichens are poikilohydric organisms whose biochemistry is strongly shaped by environmental conditions, yet their metabolome-wide adaptations across habitats remain unexplored.MethodsHere, we established a con...

The lichen diversity of the Similipal Biosphere Reserve in Odisha remains underexplored, particularly for fruticose lichens genus Cladonia P. Browne. The present study aims to document a specimen collected from the high-...

Over the past four decades, global actualistic taphonomy studies have grown significantly, driven by increased interest in present day patterns and processes of fossilization. South America has mirrored this trend, thoug...

Abstract Background Lichens produce several secondary metabolites with significant biological and pharmacological activities, among which usnic acid (UA) is particularly notable. This study aimed to investigate the cytot...

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 e verificar os padrões f...

RESUMOCanoparmelia amazonica, C. [Crespoa] crozalsiana, C. cryptochlorophaea, C. [Parmelinella] salacinifera e C. texana, são mencionadas para os Estados do Maranhão e/ou Tocantins, Brasil. Todas são novas ocorrência...
