“…The displacement rate of Pseudoscorpiones on V. divergens tree trunks was very low in comparison to the results obtained in the flooded forests of the Amazon, where the migration rate from the soil towards the canopy, as well as from the canopy toward the soil is quite high (Adis, 1981;1992;De Morais et al, 1997). One of the causes of this lower migration rate of Pseudoscorpiones may be associated with lower amplitude and duration of floods in the Pantanal as compared to the Amazon.…”

“…Both the density and the richness of Pseudoscorpiones species in the edaphic stratum in "cambarazal" were reduced when compared with the results obtained in similar studies in the Central Amazon 1990, a, b;1993;De Morais et al, 1997). Adis and Mahnert (1990, a) affirm that in non-flooded forests, the majority of the pseudoscorpion species are terricolous, while in seasonally flooded forests there is a strong synchronization between the species phenology and flood periods, with the majority of the species in these areas being arboreal, considering the lower impact caused by the flooding of the forest.…”

“…In Brazil, most of the ecological studies on Pseudoscorpiones were carried out in the Central Amazon (Adis, 1981;1990, a, b;1993;De Morais, Adis, Mahnert, & Berti-Filho, 1997;Aguiar & Bührnheim, 1998, a, b;2003;Aguiar, Gualberto, & Franklin, 2006). Some populations of Pseudoscorpiones may have undergone extensive evolution within inundation forests in this region, due to forest isolation caused by climatic shifts and micro-geographic changes (Adis & Schubart, 1984).…”

Pseudoscorpions embrace a diverse group of arachnids with approximately 3 500 species that occur in various habitats, such as soil, leaf litter, caves and canopies. This study aimed at evaluating the relationship between the pseudoscorpion assemblages in soil, termite nests, tree trunks and canopies, as well as the temporal distribution as to the abundance and richness of species in these habitats. For this purpose different sampling techniques were applied in an integrated manner in distinct habitats of a seasonally flooded monodominant forest in the Northern Pantanal of Mato Grosso, Brazil. Data regarding the abundance and richness of assemblage species were organized by means of the Non-Metric Multidimensional Scaling (NMDS). A total of 2 068 Pseudoscorpiones distributed in seven families and 18 species were captured. Chernetidae (8 spp.) and Withiidae (5 spp.) predominated, while Atemnidae, Cheiridiidae, Geogarypidae, Lechytiidae and Olpiidae were present with only one species each. Terrestrial fauna was more abundant (1 035 ind.; 50.0 % of the total catch) with three families and 10 species. In the arboreal fauna (712 ind.; 34.4 %), four families and 13 species were found. Termite mounds (321 ind.; 15.6 %) corresponded to the habitat with the least number of individuals, however, five families and nine species were identified, including Parachernes sp. 2, Geogarypus sp. and Olpiolum sp., not found in other analyzed habitats in this forest. The analyses did not show any temporal variation as to abundance or richness of Pseudoscorpiones in each evaluated habitat; however, the analysis showed that the edaphic environment (soil + termite nests), tree trunks and tree canopies are distinct habitats in relation to the composition of the assemblage. The occurrence of typical terricolous (e.g. Parawithius sp., Withiidae gen. sp. and Parachernes sp.) and other arboricolous (e.g. Cheiridium sp., Americhernes sp. and Lustrochernes sp.) species highlights the vertical stratification of the assemblage present in this floodplain forest in the Pantanal of Mato Grosso.

“…A maior densidade de Pseudoscorpiones foi observada em fl oresta secundária, seguida de fl oresta primária, provavelmente devido à maior abundância de Acari e Collembola, dos quais eles se alimentam. Mais de 60 espécies já foram identifi cadas em outros tipos de fl oresta da Amazônia (Adis & Mahnert 1990, Morais et al 1997a, provavelmente devido ao método mais efi ciente de captura (Kempson et al 1963) utilizado por esses autores (Morais et al 1997).…”

-The mesofauna has an important function in the soil and it is represented mainly by Acari Oribatida and Collembola. We report the fi rst data on the density and diversity of the soil mesofauna in Benjamin Constant, Amazonas State, Brazil. The following systems were evaluated: primary forest, secondary forest, agroforestry system, cultivated areas and pastures. A total of 101 samples were collected 100 m apart from each other and specimens were collected by using Berlese-Tullgren method. The highest density was registered in secondary forest (29,776 specimens.m -2 ). Acari Oribatida was the dominant group (7.072 specimens.m -2 ) in the pasture, suggesting that mites show higher capacity of adaptation to disturbed environments and/or due to the presence of gregarious species. The density of Collembola (5,632 specimens.m -2 ) was higher in secondary forest. Formicidae was the dominant group (27,824 specimens.m -2 ) and its highest density occurred in the secondary forest (12,336 specimens.m -2 ). Seven species and ten morphospecies of Isoptera and three species of Symphyla were identifi ed. The highest density and diversity were found in secondary forest. One supposes that the low density of mesofauna found in all of the studied systems is being infl uenced by soil structure and composition as well as litter volume. For SUT, the composition of taxonomic groups in the cultivated areas is similar to the one found in primary forest, while the groups found in the agroforestry system are similar to those in the pasture, which may help to decide on land use strategies.

“…Algunos autores como Weygoldt (1969), Gabbutt (1970), de Morais et al (1997, o Aguiar et al (2006) sugieren una estrecha relación de la abundancia de los pseudoescorpiones con la estructura vegetal de la zona; asimismo, estos arácnidos se encuentran ocupando uno o varios microhábitats (Murienne et al, 2008;Battirola et al, 2017). Por tanto, con mayor esfuerzo de muestreo explorando otros hábitats y empleando otras técnicas de muestreo, se podrán obtener mayores valores de riqueza de la fauna de pseudoescorpiones (Bedoya-Roqueme et al, 2017b).…”
