New records of lichens in Sierra Nevada de Santa Marta
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.

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.

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.

|研究區域描述||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.|
|研究設計描述||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).|
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.
