“…One interesting aspect of this ecological association is that it seems not to be influenced as much by landscape-level features than by site-level forest characteristics (Rojas et al 2017). In this sense, even though for the general analysis, the sampling of this type of substrate was proportionally lower than other ones such as wood and bark, results showed a high potential for hypothesis testing studies and conservation approaches.…”

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.

Two experiments employing a modified version of the standard "Cavender Method" were used to evaluate the incidence patterns of myxomycete and dictyostelids associated with different soils collected across north and central America. The soils were subjected to variable culturing conditions and parameters including plant material quality, agar type and bacterial food source. Ecological variables such as geographic location and land use quality were also evaluated to determine potential differences affecting the soils. The study also aimed to document the potential for mycetozoans to serve as indicators of ecosystem quality. The results indicated that plant materials with middle hardness and moderate cellulose to lignin ratio, in conjunction with an intermediate rich culturing media favoured the growth of mycetozoans. Also, Bacillus subtilis represented a suitable alternative to Escherichia coli. Dictyostelids were more commonly recovered from tropical soils than temperate soils, while the opposite pattern was observed for myxomycetes. No differences in mycetozoan incidence were detected when landscape-scale and soil quality parameters were examined. Overall, data related to the utility of using mycetozoans as bioindicators are still limited, but the results of this study suggest that more targeted, scaledependent studies are warranted. The modified protocol used herein appears to represent a reliable method to generate consistent data for ecological studies of mycetozoans, particularly when tropical soils are used.
