Novelties for the bryophyte flora of Chaco Province, North of Argentina

Background and aim: Bryophytes are an important group of plants in forest ecosystems that act as primary colonizers, moisture regulators and nutrient fixers. Due to their sensitivity to disturbance, they are used as bioindicators in impact studies. Nevertheless, there are extensive areas poorly stud...

description Background and aim: Bryophytes are an important group of plants in forest ecosystems that act as primary colonizers, moisture regulators and nutrient fixers. Due to their sensitivity to disturbance, they are used as bioindicators in impact studies. Nevertheless, there are extensive areas poorly studied that currently are undergoing significant changes due to agricultural and livestock practices, as is the case in Chaco. As part of a major project which aims to determine the impact on land-use change on the bryophyte diversity in Chaco, samples collected in the region have been analyzed with the aim of updating knowledge of the bryophyte flora in the province. M&M: Samples from preserved and non-preserved areas from Chaco were studied according to the traditional techniques for bryophytes and mounted in water-glycerin-phenol or Hoyer´s solution. Results: As a result, 26 species distributed in 19 genera and 13 families, are newly recorded to Chaco province. Conclusions: The results improved our understanding of a poorly explored flora in a region with unique characteristics. These findings reinforce the value of floristic studies to collect data about poorly known species and their distribution, and to provide a basis for applied studies. In Argentina, despite efforts made in recent decades, there is still a lack of understanding regarding bryophyte diversity. This, combined with rapid changes in land use, may lead to the alteration or disappearance of bryophyte communities before they are even studied.

Introducción y objetivo: Los briófitos son un grupo importante de plantas en ecosistemas boscosos, que actúan como colonizadores primarios, reguladores de humedad y fijadores de nutrientes. Debido a su sensibilidad ante disturbios, son utilizados como bioindicadores en estudios de impacto. Sin embargo, existen extensas áreas escasamente estudiadas que están sufriendo cambios debido a las prácticas agrícolas y ganaderas, como ocurre en Chaco. En el marco de un proyecto mayor cuyo objetivo es determinar el impacto del cambio en el uso del suelo sobre la diversidad briofítica del Chaco, se analizaron las especies recolectadas en la región con el fin de actualizar el conocimiento de esta flora en la provincia. M&M: Ejemplares provenientes de áreas protegidas y no protegidas de Chaco fueron estudiados de acuerdo a técnicas tradicionales para briófitos, y montados en agua-glicerina-fenol o solución de Hoyer. Resultados: Como resultado, 26 especies, distribuidas en 19 géneros y 13 familias, son registrados como nuevos para la provincia del Chaco. Conclusiones: Los resultados mejoran nuestra comprensión de una flora poco explorada en una región de características singulares. Estos hallazgos refuerzan el valor de los estudios florísticos para recopilar datos de especies poco conocidas y su distribución, y proporcionar una base para estudios aplicados. En Argentina, pese a los esfuerzos realizados en las últimas décadas, aún existen vacíos en el conocimiento sobre la diversidad de briófitos. Esto, combinado con los rápidos cambios en el uso del suelo, puede llevar a la alteración o desaparición de comunidades de briófitos antes de que sean estudiadas.
