Abstract
Abstract: The Brazilian Pantanal biome is one of the largest and most important floodplains in the world by virtue of its biodiversity and indispensable ecological services on local, regional, and global scales. Despite this importance, many gaps remain concerning its biodiversity as well as its generation and maintenance mechanisms. In view of expanding the information about its biological diversity, we compiled a list of Myriapoda (Arthropoda) species occurring in the Pantanal of Poconé, Mato Grosso, Brazil, based on the records from literature and on the specimens available in the zoological collections of Federal University of Mato Grosso -UFMT. A total of 33 Myriapoda species were recorded in the region. The Diplopoda species (20 spp.; 60.6%) are distributed 'between four orders: Polydesmida, represented by five families (Chelodesmidae, notably, with three species; Paradoxosomatidae and Pyrgodesmidae, with two species each; and Cyrtodesmidae and Fuhrmannodesmidae, with one species each, recently recorded in the region); Spirostreptida, represented by Spirostreptidae, with eight species; Spirobolida, with two species (one Rhinocricidae and one not identified); and Polyxenida. The Chilopoda (10 spp.; 30.3%) belong to three orders: Scolopendromorpha, with four species of the family Scolopendridae, two Scolopocryptopidae species, and one Cryptopidae species; Geophilomorpha, with the families Aphilodontidae and Schendylidae, with one species each; and Lithobiomorpha, with one Henicopidae species. Symphyla was represented by only two species (6.1%) of the family Scutigerellidae; and Pauropoda (3.0%) by a single species of Pauropodidae. The Myriapoda species richness, as well as the high number of new records in recent studies reinforce the importance of the northern region of the Pantanal biome as a diversity center with potential priority for measures aimed at the conservation of its many habitats.
Highlights
Wetlands are defined as ecosystems inserted at the interface between terrestrial and aquatic, continental and coastal, natural or artificial environments which may permanently or periodically be flooded by shallow, fresh, briny, or salt water (Junk et al 2015)
The present study presents a compilation of information available in the literature and in different zoological collections of the Federal University of Mato Grosso on the occurrence of these taxa in the Pantanal of Poconé - MT, to expand the knowledge of the biodiversity of the Pantanal of Mato Grosso State
We used Myriapoda (Diplopoda, Chilopoda, Symphyla, and Pauropoda) occurrence metadata available in the scientific literature referring to the Pantanal of Poconé region (Figure 1) as well as the results obtained in studies led by the teams of the Laboratory of Ecology and Taxonomy of Terrestrial and Aquatic Arthropods (LETA) of the Bioscience Institute at the Federal University of Mato Grosso, in Cuiabá, Mato Grosso; of the Biological Collection of Southern Amazon (ABAM) at the Federal University of Mato Grosso, in Sinop, Mato Grosso; and of the Zoological Collection of the Federal University of Mato Grosso, in Cuiabá, Mato Grosso
Summary
Wetlands are defined as ecosystems inserted at the interface between terrestrial and aquatic, continental and coastal, natural or artificial environments which may permanently or periodically be flooded by shallow, fresh, briny, or salt water (Junk et al 2015) These areas provide important ecological services on both local and global scales, with functional values related mainly to the renewal of groundwater stores, storage and maintenance of increased atmospheric humidity, protection against soil erosion, water purification, organic carbon storage, and their consequent impact on climatic conditions (Denny 1994). The region floods due to the lateral overflow of great rivers or lakes, precipitation, or underground water, and the flood is classified according to its amplitude, frequency, predictability and strength (Signor et al 2010, Junk et al 2015)
