“…Nevertheless, we found that C. agnotus was associated with S. bondari (Hymentopera: Formicidae), whereas C. similis was associated with T. cornetzi. Mucrosomia (Iso tomidae: Anurophorinae) was recorded for the first time in ant nests; until now this genus has been found in Brazil only by Mendonça and Queiroz (2013) in mountains of the southeast of the country, whereas the other 3 known species occur in Europe (Potapov 2001). The species Proisotoma minima (Collembola: Isotomidae) has been recorded once previously associated with Ponerinae (Hymenoptera: Formicidae) ant nests found in cacao pods (Castaño-Meneses et al 2014).…”

Four species of Collembola were found in nests of the ant genera Myrmicocrypta, Trachymyrmex and Sericomyrmex of the tribe Attini (Formicidae: Myrmicinae). The panmyrmecophilic collembolan Cyphoderus (Lepidocyrtidae: Cyphoderinae) was the most abundant and was associated with all the ants. The collembolan genus Mucrosomia (Isotomidae: Anurophorinae) was found for the first time in ant nests. This is the first list of springtails found in nests of fungus-growing ants other than those belonging to the genera Atta and Acromyrmex (Formicidae: Myrmicinae).

“…To determine the reproduction rate of the P. minuta species, the method used was dry extraction in Berlese-Tüllgren funnels for a period of 24 hours with subsequent addition of water and red dye. This adaptation was necessary due to the smaller size and color of the species' exoskeleton (Hopkin, 1997;Mendonça;Queiroz;Silveira, 2015). Afterwards, the samples containing the organisms were carefully shaken and the number of individuals determined using ImageJ 1.54d software (NHI, 2023).…”

Copper is a trace element in plants and animals whose importance can be understood due to its role in different essential metabolic processes. Anthropogenic activities such as agriculture and mining are potential sources of pollution due to the emission of copper into the environment. Brazilian legislation ties soil quality to guideline values, among which the Prevention Value indicates the critical environmental limit for trace elements. The aim of this study was to obtain PVs for copper for two subtropical soils (Cambisol and Nitisol), given that the pedological richness was not considered when deriving the PVs contained in the federal normative. Reproduction assays followed ISO guidelines with the earthworm species Eisenia andrei and Perionyx excavatus, the enchytraeids Enchytraeus crypticus and E. bigeminus and the springtails Folsomia candida and Proisotoma minuta. Results showed that the sensitivity of the organisms was greater in Cambisol. The most sensitive species were the earthworms, especially P. excavatus (EC50 = 67.83 in Cambisol; EC50 = 264.96 in Nitisol). The springtails, on the other hand, were the least sensitive to contamination. These findings reinforce the need to include organisms from different ecological groups in ecotoxicological assessments. It was also observed that the PV adopted in federal legislation (= 60 mg kg-1) is in fact protective for the species and soils we evaluated, since the PVs we obtained based on the EC50 were 346.74 mg kg-1 in Nitisol and 134.05 mg kg-1 in Cambisol. It is important to note that our results do not exclude the need for evaluations with other subtropical soils, given the influence of their properties on the toxicity and bioavailability of copper to soil organisms.

“…With the increasing number of descriptions of new taxa and faunistic surveys, in the last few years, that number has increased to 315 species in 98 genera of 21 families. The new supraspecific records are as follows: Mucrosomia Bagnall, 1949 (Mendonça & Queiroz 2013); Varelasminthurus Silva, Palacios-Vargas & Bellini, 2015(Silva et al 2015; Isotogastrura Thibaud & Najt, 1992 (new record for Isotogastruridae) (Palacios-Vargas et al 2013;Silveira et al 2014); and Collophora Richards in Delamare Deboutteville & Massoud, 1964 (new record for Collophoridae) (Zeppelini & Brito 2013).…”
