Diversity patterns, ecological associations and future of research on Costa Rican myxomycetes

Abstract

The most active research period on myxomycetes in Costa Rica has taken place in the last three decades. During this time, most of the collections have been carried out and most of the scientific articles have been produced. However, the lack of standard protocols and systematic planning across the country generated a need to conduct an analysis of myxomycete records to define future lines of work. A compilation, cleaning, standardisation and analysis of information associated with a database of more than 7800 records that comprised 242 species of myxomycetes reported in Costa Rica during the last 110 years, was carried out. An interpretation of data with a conservation approach that integrated elements of data-mining and geographical information systems was conducted. Results showed that myxomycetes has been comparatively well studied in Costa Rica in relation to other regional or tropical countries. However, survey effort has been unequal within the territory, leaving some interesting areas or substrates understudied. The absence of long-term goals to study this country and Mesoamerica has limited the potential that the analysed data can have within the context of conservation. This could be the next logical step in the study of this group of microorganisms in that country.
