ROCABADO, Diana  and  MAILLARD, Oswaldo. Abundance of gasteroid Fungi in the northern Bolivian Amazon. Ecología en Bolivia [online]. 2019, vol.54, n.2, pp.72-82. ISSN 1605-2528.

This study was carried out in four sites of the Amazonian forests in the north of the country, in the Departments of Pando (Las Ruinas, Candelaria) and Beni (Las Palmeras, 7 de Julio), with the main objective of evaluating the abundance of the gasteroid fungi and their relation with precipitation, maximum temperature, canopy light inlet and understory cover. The method of sampling used consisted of collections carried out in four plots of 50 x 50 m, divided in turn in 50 circular subplots of 5 m in diameter. Samplings were developed in the humid (November-January) and dry season (July-September). A total of 83 samples of gasteriod fungi were collected from the genera Geastrum and Lycoperdon. The abundances of fungi per locality showed a significant variation (F = 8.78; P = 0.0002), where the locality of Las Ruinas presented the largest number of individuals. On the other hand, the abundance of fungi was significantly different between sampling times (F = 33.14, P = 0.0001), presenting greater abundance in the rainy season. As for the entrance of canopy light, vegetation cover, precipitation and maximum temperature, it was not found that there is a relationship with the abundance of gasteroid fungi.
