Preliminary record of annual atmospheric deposit of fern spores from the Yungas over an environmental gradient in the middle basin of rio Perico (Jujuy, Argentina)

The aim of this work was to record the fern spores biological richness, to analyze their relative representation as well as their annual atmospheric deposit rate present in aerobiological traps, on a gradient transition in the Montane Forest of Yungas from Northwest Argentina (1900 m-2600 m a.s.l.)....

The study contributes with preliminary deposit rates of fern spores, achieving advances in the knowledge of their aerobiological characteristics. This expands the knowledge of the current environment and serves as reference information for paleoenvironmental studies of the region. The study provides preliminary data on the rate of deposition of fern spores of the Yungas, making progress in the knowledge of the plant group, scarcely known from the aerobiological point of view. 2014 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_0373580X_v49_n4_p503_Torres http://hdl.handle.net/20.500.12110/paper_0373580X_v49_n4_p503_Torres
