The southernmost distribution range of Isoetes panamensis Maxon & C.V. Morton (Lycopodiopsida, Isoetaceae) in the relicts of the Cerrado in southern Brazil

Abstract

Establishing the geographical distribution limits of species may provide not only data to understand their range of adaptation to conservation proposals but also records of the dynamics in the vegetation across the time. Here we report the southernmost limit of the occurrence of Isoetes panamensis Maxon & C.V. Morton within a relict of the Cerrado in Paraná, Brazil. This find highlights the importance of fieldwork in relicts of the Cerrado to enhance the knowledge about the flora of Paraná and the vegetational dynamic of the Cerrado in the past.

New records of four tree species in the state of Paraná, southern Brazil: Canellaceae, Lauraceae, Melastomataceae, and Myristicaceae

“…estimated about 6,430 species of native vascular plants in Paraná, including 5,990 angiosperms, 436 ferns and lycophytes, and four gymnosperms. However, this number has gradually been increased as new records are made Goldenberg 2014, 2016;Lozano et al 2016Lozano et al , 2018Brotto et al 2019;Souza et al 2019;Pereira et al 2021).…”
