New records of lichens in Sierra Nevada de Santa Marta

Latest version published by Check List on Oct 27, 2020 Check List

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.

Geographic Coverage

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.

Bounding Coordinates South West [10.282, -74.273], North East [11.356, -73.026]

Taxonomic Coverage

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.

Project Data

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.

Title New records of lichenized fungi in Sierra Nevada de Santa Marta, Colombia
Funding Ministerio de Ciencia, Tecnología e Innovación (Minciencias) Vice-Rectory for Research at the Universidad del Magdalena
Study Area Description The northwestern slope of the SNSM, located in Magdalena department, is characterized by a diversity of ecosystems: tropical dry deciduous forest and thorny and succulent thickets (8–180 m a.s.l.), tropical semi-deciduous forest (180–600 m a.s.l.), sub-desert ombrophilous forest (600–1800 m a.s.l.), and Andean forest (1800–2800 m a.s.l.). The area is also characterized by a great variety of climates: arid warm, warm dry, warm humid, very humid temperate, and very humid cold, and a unimodal-biseasonal rainfall pattern, with a longer period of precipitation between May and November, and lower precipitation from December to April.
Design Description Here we provide the results of the first explorations carried out on the northwestern slopes of the SNSM; we present data for 19 newly recorded species on this massif and the Magdalena. 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. 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. 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).

Sampling Methods

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.

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

Method step description:

  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).
