ALVAREZ-LEON, Ricardo; AVENDANO-REMOLINA, Darío  and  SANJUAN-MUNOZ, Adolfo M. THE RELATIONSHIP BETWEEN PELTIGERA SP. AND RHIZOPHORA MANGLE IN ARROYO DE PLATA (BOLIVAR), COLOMBIAN CARIBBEAN REGION. Luna Azul [online]. 2014, n.38, pp.105-121. ISSN 1909-2474.

Objective: To determine the distribution and status of mangrove stands in Arroyo de Plata (Department of Bolívar). Methodology: Field work was conducted through woodland, using biological sampling of the flora and the physical and chemical parameters of water and soil along transects within the forest. Results: The composition of the stand includes five species, Rhizophoramangle (red, colorao or colorado mangrove), Avicenniagerminans (salty, dark color, black or iguanero mangle) Laguncularia racemosa (white, yellow or bobo mangrove), Conocarpus erecta (zaragoza mangle) and Pelliciera rhizophorae (tea mangrove). The lichen (Peltigera sp), was found associated with the pioneer species (R. mangrove) whose relationship is carried out only when the mangrove is in a state of degradation and the physical-chemical parameters of water and soil, are extreme. Conclusion: Mangroves showed mature coastal basin type mixed characteristics, where the invasive species P. rhizophorae has the highest IVI due to its high density. Registration of Peltigera sp lichens and its presence of the Colombian Caribbean mangrove is not only the first for this region, its distribution may be restricted to the coastal zone, it is incidental and demonstrates its ability to adapt to environmental changes, and can be considered between the bio-indicators of environmental characteristics, especially of the the current alterations of soil and water.
