Chaimowiczia: a new Iuiuniscinae genus from Brazil (Oniscidea, Synocheta, Styloniscidae) with the description of two new troglobitic species
(2021-06-08) Cardoso, Giovanna Monticelli; Bastos-Pereira, Rafaela; Souza, Leila Aparecida; Ferreira, Rodrigo L.
A new genus of Styloniscidae, Chaimowiczia gen. nov., is described with two new species: Chaimowiczia tatus sp. nov. from Gruta do Padre cave (Santana, Bahia) and Chaimowiczia uai sp. nov. from Lapa d’água do Zezé cave (Itacarambi, Minas Gerais). The new genus and species were allocated into the subfamily Iuiuniscinae, hitherto monotypic, by the pronounced rectangular-shaped lateral pereonites epimera, dorsal surface smooth, body outline continuous without a gap between pereon and pleon, and pleonites 3 to 5 developed forming tips. The two species of Chaimowiczia gen. nov. differ in the shape of cephalon antennal lobes, pereonite 1 epimera, pleonite 5 posterior margin and uropod exopod and endopod proportion.

A new species of Chaimowiczia from the karstic Serra do Ramalho plateau, Brazil (Oniscidea, Synocheta, Styloniscidae)
(2022-03-29) Cardoso, Giovanna Monticelli; Bastos-Pereira, Rafaela; Ferreira, Rodrigo Lopes
Chaimowiczia belongs to the subfamily Iuiuniscinae, family Styloniscidae, and is currently composed of two troglobitic species: C. tatus and C. uai, both occurring in Brazil. A new species of Styloniscidae found in Brazil (Bahia state, Serra do Ramalho, Serra Verde cave) was allocated into this genus by the antenna flagellum with three articles; rectangular-shaped lateral pereonites epimera not apically acute and apex of pleopod 2 endopod with an acute tip and an acute or rounded lobe directed outwards. The new species, C. obybytyra sp. nov., is here described and rises to 25 the number of troglobitic styloniscidean species known for Brazilian caves.

Quantification of Geodiversity Services in the São Francisco River Basin, Brazil (Minas Gerais portion), and Their Importance for the Management of Water Resources
(2023) Santos, M.D.; de Azevedo Ruchkys, Ú; Pereira, E.O
The São Francisco River basin (SFRB) is the largest hydrographic basin located exclusively in Brazil. It covers an area of 636,920 km2, encompassing seven states. From its source, in the Serra da Canastra National Park in the state of Minas Gerais, the river flows for about 2700 km to its mouth, on the border of the states of Sergipe and Alagoas. It passes through regions rich in natural and cultural resources that are considered strategic for its development. Its management has been a challenge for the different agencies involved in the environmental sector. Thus, the objective of this study is to quantitatively map the geodiversity services, in addition to showing areas of density of these services, in the São Francisco River basin in Minas Gerais using planning units denominated Hydrographic Circumscriptions (CHs), proposed by the Instituto Mineiro de Gestão das Águas (Minas Gerais Institute for Water Management) (IGAM) as reference. The methods employed were quantification and spatialization of geodiversity services by CHs and comparison between them. The results indicate that the integrated assessment of geodiversity services proved to be satisfactory, enabling the identification of the most prominent services in each CH, in addition to making it possible to innovatively support the management of water resources in Brazil.
