Myriapod (Arthropoda, Myriapoda) diversity and distribution in a floodplain forest of the Brazilian Pantanal
This study presents the diversity and distribution of myriapod species associated with different habitats in a seasonally flooded forest composed predominantly of Vochysia divergens Pohl. (Vochysiaceae) in the Brazilian Pantanal. We evaluated species richness distribution across habitats and over different seasonal periods, and also identified possible survival strategies employed during periodic flooding that occur within this forest. A total of 1505myriapods were sampled, representing four classes and 15 species. Diplopoda and Chilopoda were the most abundant and rich taxa. Pauropoda and Symphyla were represented by only one species each. Species richness was distinctly distributed across habitats evaluated in this forest, as well as over the different seasonal periods. Survival strategies observed in Diplopoda and Chilopoda were primarily associated with vertical migration ranging from the edaphic environment to tree trunks and canopies, and horizontal migration associated with water level before and during the flood period. Species richness was considered low; however, the survival strategies, especially vertical and horizontal migration, demonstrate the adaptation of these species to the seasonal floods of this ecosystem.
