New records of lichens in Sierra Nevada de Santa Marta

Description

The lichen diversity of the Caribbean region of Colombia is one of the least known in the county. In the Sierra Nevada de Santa Marta (SNSM), whose forests are at risk of disappearing due to deforestation, 114 species of lichens have been recorded. We collected lichens at elevations from 500 to 2500 m on the northwestern slopes of the SNSM, and we report six genera and 19 species from this region for the first time. Our results highlight the importance of exploring new areas to enhance our knowledge of the lichens of SNSM and Colombia.

Sampling Description

Study Extent

We provide the results of the first explorations carried out on the northwestern slopes of the SNSM.

Sampling

Samples were collected from the forests and coffee crops of the study area, in an elevation gradient from 500 to 2500 m a.s.l., applying the opportunistic sampling method. The collection was manual, using a razor to separate the sample from the substrate. Samples were stored in paper bags, where field data were also recorded. The material was stored in a freezer at −20 °C for two days to remove invertebrates; later it was dehydrated at room temperature and stored in acid-free paper envelopes with their respective label.

Method steps

  1. Taxonomic keys were used to identify the material. For identification of genera, keys such as Sipman (2005) and Cáceres (2007) were used. In addition to illustrations, descriptions, and expert collaboration from the Grupo Colombiano de Liquenología (GCOL), specialized keys and monographs were used for species identification: Stereocaulon Hoffm. (Boekhout 1982; Sipman 2002; Rincón-Espitia and Mateus 2013); Heterodermia Trevis. and related taxa (Moberg 2011; Mongkolsuk et al. 2015; Díaz-Escandón 2017); Ramalina Ach. (Gumboski 2016); Coenogonium Ehrenb. (Rivas-Plata et al. 2006); Bulbothrix Hale (Benatti 2012, 2014). Chemical tests with 10% aqueous potassium hydroxide (K) and 6% sodium hypochlorite (C) were performed. The specimens were deposited in the Centro de Colecciones Biológicas de la Universidad del Magdalena (CBUMAG).

Taxonomic Coverages

Six genera were recorded for the first time for SNSM: Bulbothrix (Parmeliaceae), Chrysothrix Mont. (Chrysothricaceae), Coenogonium (Coenogoniaceae), Dibaeis (Icmadophilaceae), Heterodermia, and Polyblastidium (Physciaceae). Additionally, 19 species were recorded for the first time.

Geographic Coverages

The Sierra Nevada de Santa Marta (SNSM) is located on the Caribbean coast of northern Colombia and has an area of approximately 17,000 km2 covering the departments of Magdalena, Cesar, and La Guajira. It is the highest coastal mountain range in the world, with a maximum elevation of 5,775 m a.s.l.
