Cosmarium bromelicola sp. nov. (Desmidiaceae, Zygnematophyceae), a new desmid species from Northeast Brazil

Abstract

Cosmarium bromelicola sp. nov. is a new desmid species described from samplings carried out in bromeliad tanks (phytotelmata) from an area of rocky outcrops at Serra da Jiboia, Bahia State, Northeast Brazil. Presence of subtrapeziform cells with a deep depression at the apical region and twisted X-shaped cell in side view are the diagnostic features for the species. Relationships with the morphologically closest taxa are discussed.

Bromeliad phytotelmata: the first scientometric study

“…Another important point that may have influenced the increase in the number of publications was the creation and expansion of ecological research centers in South America. In Brazil, the expansion of these research centers began precisely in 2003, with the expansion of university campuses to the interior of the states (Buosi et al, 2015;Ramos et al, 2019;Trombini et al, 2020), in a period when the Brazilian economy was growing rapidly (2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011). This financial contribution provided researchers with better working conditions and diversification of research systems, such as bromeliad phytotelmata.…”

“…One of the reasons for the increase in knowledge about biodiversity in this period may be the greater number of publications at an ecosystem level, with predictive analyses and experimental studies of complex food webs, with the inclusion of organisms from primary producers like bacteria and algae (Salinas et al, 2018;Cereghino et al, 2019;Cereghino et al, 2020). Another important factor was that there was an increase in the diversity of the studied organisms, such as a description of new species of desmids of the genus Cosmarium (Ramos et al, 2018;Ramos et al, 2019) and new records of little-studied groups in phytotelmata, such as viruses, cyanobacteria, tecameba and fungi, expanding the knowledge of their spatial distribution (Trzcinski et al, 2016;Kratina et al, 2017;Mendes et al, 2019).…”

Periphytic algal flora of the lower Doce river basin after ore tailings flow, Espírito Santo State, Brazil: Sampling design and methods

“…Menezes et al (2015) recorded 4,747 species of algae and cyanobacteria for Brazil. This number is increasing even more with several study efforts, such as the algae flora of streams in the Parnaíba River basin (Auricchio et al 2019), checklist of the Cosmarium in Brazil (Biolo & Bicudo 2018), floristic survey of urban parks (D'alessandro & Nogueira 2017), and descriptions of new species (Ramos et al 2017, Lehmkuhl et al 2019, Ramos et al 2019, Zorzal-Almeida et al 2020. One of the most relevant studies about Brazilian microalgae flora is the survey of the 'Algal Flora of the Parque Estadual das Fontes do Ipiranga (PEFI)', which started in 1962 and registered 869 taxa in 42 fascicles (Bicudo 2020).…”
