Corticolous cyanobacteria from tropical forest remnants in northwestern São Paulo State, Brazil

Abstract

-(Corticolous cyanobacteria from tropical forest remnants in northwestern São Paulo State, Brazil). Cyanobacteria are common in aquatic environments but are also well-adapted to terrestrial habitats where they are represented by a diversified flora. The present study aimed to contribute to our taxonomic knowledge of terrestrial cyanobacteria by way of a floristic survey of the main components of corticolous communities found in seasonal semideciduous forest fragments. Samples of visible growths of Cyanobacteria, algae, and bryophytes found on tree bark were randomly collected and their taxonomies examined. Eighteen species of Cyanobacteria were found belonging to the genera Aphanothece, Chroococcus, Lyngbya, Phormidium, Porphyrosiphon, Hapalosiphon, Hassalia, Nostoc, Scytonema, and Stigonema. Many genera and species observed in the present work have been reported in previous surveys of the aerophytic flora in several regions of the world, although six species were described only on the basis of populations found in the forest fragments studied, which highlights the importance of taxonomic studies of cyanobacteria in these habitats.

Thainema gen. nov. (Leptolyngbyaceae, Synechococcales): A new genus of simple trichal cyanobacteria isolated from a solar saltern environment in Thailand

“…Cyanobacteria are ubiquitous microorganisms abundantly found in a wide range of terrestrial and aquatic habitats [1]. These microorganisms played a crucial role in the evolution of life on Earth by producing and releasing oxygen into the atmosphere, starting approximately 2.5 billion years ago [2].…”

Community structure of corticolous microalgae within a single forest stand: evaluating the effects of bark surface pH and tree species

“…Still, such studies are relatively labourious, as they typically involve microscopic inspection of numerous Petri dishes, typically with hundreds of algal microcolonies. Alternatively, community structure of corticolous algae may also be studied by direct microscopy of biofilms (hedeNås et al 2007;Lemes-da-siLva et al 2012;Neustupa & Štifterová 2013). This method allows relatively large numbers of samples to be surveyed, but it lacks taxonomic resolution among many species and genera, especially the coccoid green algae.…”

Polyhydroxybutyrate-producing cyanobacteria from lampenflora: The case study of the “Stiffe” caves in Italy

“…In this study, we have focused our attention on the cyanobacteria of lampenflora. Cyanobacteria are an ancient lineage of slow-growing ubiquitous photosynthetic prokaryotes found in a wide range of terrestrial and aquatic lightened environments ( Abed and Garcia-Pichel, 2001 ; Abed et al, 2009 ; Lemes-da-Silva et al, 2011 ; Panou and Gkelis, 2022 ). Cyanobacteria are the most important primary producers on Earth, including extreme environments ( Gan and Bryant, 2015 ).…”
