Abstract:RESUMO -(Briófitas do Município de Poconé, Pantanal de Mato Grosso, MT, Brasil). Sofrendo influências de outros ecossistemas, tais como o Cerrado e a Floresta Amazônica, o Pantanal de Mato Grosso constitui um ecossistema único. Embora sua flora fanerogâmica seja relativamente bem conhecida, a brioflora ainda necessita ser estudada mais profundamente. Fazendo parte da bacia do bio Paraguai e localizado a 94,8km de Cuiabá nas coordenadas 16º15'24"S e 56º36'24"W,

“…(Pottiaceae) is described in the literature as occurring from Mexico to Brazil (Sharp et al, 1994), but in Brazil it is recorded only to the Northeast and Southeast (Forzza et al, 2010). This new record is an important fill of the gap in the Mid-West, and encourages the development of new researches in this region, as commented by Câmara and Vital (2004).…”
The Cerrado is a savanna formation predominantly located in the central Brazilian plateau; this vegetation is rich in bryophytes. This study analyzes bryophyte diversity, composition and distribution among various Cerrado vegetation types (Gallery Forest, Deciduous Forest, Rupestrian Cerrado and Rupestrian Fields) and substrates in the Área de Proteção Ambiental Morro do Macaco, from municipality of Iporá, Goiás state, in Central-West Brazil. The collection was performed in four plots of 20m x 20m, in each vegetation types, from August to December 2010, the data were analyzed with the Shannon-Wiener (H') and Simpson diversity index and the floristic similarity with UPGMA. We found 37 species, with 28 to Bryophyta and nine to Marchantiophyta. Trichostomum brachydontium Bruch is a new record to the Brazilian Midwest and an endemic species (Archidium oblongifolium Peralta et al.) occurs in the study area. The forested areas were the richest in species number and the substrate most colonized was soil. The results extend the information about the Cerrado bryophytes, increasing the knowledge of their taxonomic diversity and ecology.

“…La flora briofítica en el campus de la UPTC-Tunja representa el 13.6% de las especies reportadas para el departamento de Boyacá (Churchill, 2016;Gradstein, 2021;Aponte et al 2022). Al comparar estos resultados con otras investigaciones realizadas en ambientes urbanos se obtienen similitudes, en la mayor cantidad de especies de musgos sobre hepáticas y antocerotes (Yano & Câmara, 2004, Stevenson & Hill, 2008Sabovljević & Grdović, 2009;Machado & Luizi-Ponzo, 2011;Quiñones et al 2021); en el mayor número de musgos acrocárpicos sobre pleurocárpicos (Durwael & Lock, 2000;Ardiles & Peñaloza, 2013;Zepeda-Gómez et al, 2014); en las familias más diversas, Pottiaceae, Bryaceae, Brachytheciaceae (Lara et al, 1991;Giudice et al, 1997;Kirmaci & Ağcagil, 2009) y Lejeuneaceae (Bastos & Bôas-Bastos, 2000;Câmara & Vital, 2004;Paiva et al, 2015) y en los géneros más representativos, como el caso de Frullania, Lejeunea (Yano, 2012), Bryum y Didymodon (Ron et al, 2008).…”
Los ambientes urbanos albergan una riqueza significativa de briófitos. Estas plantas no vasculares pueden colonizar cualquier tipo de sustrato presente en las ciudades como suelo, roca, cortezas de árboles y arbustos, hojas vivas, materiales rocosos presentes en el ladrillo, estructuras de edificaciones y concreto. Durante esta investigación se estudiaron los musgos, hepáticas y antocerotes que habitan el campus de la Universidad Pedagógica y Tecnológica de Colombia, sede Tunja (Boyacá). Para ello, se realizaron muestreos sobre los sustratos artificiales, propios de la infraestructura y sustratos naturales presentes en áreas verdes y bosques plantados en el área de estudio. Con los datos obtenidos se analizó la riqueza y composición de las briofitas, la especificidad de sustrato y la interacción de forófitos vs. briófitos. El estudio permitió reconocer un total de 80 especies y demostró que el sustrato que concentró la mayor cantidad de briófitos fue el suelo, seguido por las cortezas de los árboles y la materia orgánica en descomposición, siendo el sustrato suelo exclusivo para los antocerotes. Los forófitos con más riqueza de especies de musgos y hepáticas correspondieron a Tecoma stans (L.) Juss. ex Kunth y Pittosporum undulatum Vent. Se reportan las especies Bryum coronatum Schwägr., Fabronia jamesonii Taylor, Frullania sphaerocephala Spruce y Streptopogon cavifolius Mitt. como registros nuevos para el departamento de Boyacá.
