The Brazilian scorpion Tityus serrulatus is recorded for the first time in the central region of Rio Grande do Sul, thus filling a gap of 567 km in its distribution. A specimen of the scorpion was collected in the urban area of the municipality of Santa Maria (29°43′51.31″ S, 053°48′5.74″ W) on 31 June 2014. A map was generated with the points of occurrence of the species in the state.

A Triassic taphoflora identified in the Central Region of the State of Rio Grande do Sul, southern Brazil, represents an important biostratigraphic stage in the paleofloristic succession of the Paraná Basin. This megafloristic association is composed of compressed leaves, fronds and seeds of a “Dicroidium Flora” and shows a predominance of the Dicroidium genus, with several species, and other important taxa like Neocalamites sp, Cladophlebis sp, Tetraptilon aff, heteromerum, Ginkgoites Antarctica, Sphenobaiera sp, Podozamites sp, Nilssonia sp, Pteruchus sp and Carpolithus sp. Taking into account the stratigraphical distribution of different species of the Dicroidium genus, a biostratigraphic framework was established. The biostratigraphical position of this Triassic flora was established by comparison with Triassic floras from Argentina, South Africa and Australasia. Considering that the recognition of this Dicroidium Flora was based on limited outcrops belonging to one lithostratiphic level (Santa Maria Formation – Passo das Tropas Facies), it was impossible to establish a formal biostratigraphic zonation. Instead, at present time, an informal floristic interval, named “Dicroidium odontopteroides Flora” is proposed (Late Anisian to Late Ladinian, Middle Triassic).

Rio Grande do Sul (RS) is the southernmost state in Brazil and includes areas within the Pampa and Atlantic Forest biomes. The semiaquatic bugs (Hemiptera, Heteroptera, Gerromorpha) from RS are poorly known, with only 14 previously recorded species. We carried out two expeditions in this state, in 2002 and 2019, across 19 municipalities. Here, we provide new records for 19 species, of which 13 are recorded for the first time from the state, five have their distributions expanded, and one is recorded again from a same locality previously reported in the literature. Furthermore, 13 species were collected for the first time in the Pampa biome and one in the Atlantic Forest.

The open pollination cultivars (VPA) of maize are an alternative of production for a small property, because it presents a good agronomic performance and low production cost, mainly due to the possibility of seed production with low cost. The objective of this research was to evaluate the agronomic performance and economic viability of open pollination cultivars of maize in a low-altitude site in the central region of the state of Rio Grande do Sul. The experiment was conducted during the 2018/2019 crop season, in the experimental area of the Federal University of Santa Maria-UFSM, in the municipality of Santa Maria-RS. The open pollination maize cultivars (SCS 154 Fortuna, SCS 155 Catarina, and SCS 156 Colorado) were used. The experiment consisted of three treatments and four replicates and the experimental design used was that of complete blocks at random. The open pollination cultivars presented an adequate agronomic performance in a low-altitude region in the state of Rio Grande do Sul, associated with the economic viability of the crop in the central region of the state.

Temnocephala lutzi Monticelli, 1913, ectosymbiont on brachyuran freshwater crabs of the genus Trichodactylus Latreille, 1828 is recorded for the first time in the State of Rio Grande do Sul, southern Brazil. Two hundred and seventy-nine crabs of two species were examined: 211 Trichodactylus panoplus (von Martens, 1869) and 68 Trichodactylus fluviatilis Latreille, 1828 of which 51 (24.17%) and 28 (41.17%) were positive for T. lutzi, respectively. Crabs of both species carried eggs fixed, exclusively, on the floor of the branchial chambers and/or on the lower side of the gills. Adult as well as young specimens were found inside and outside the branchial chambers. The temnocephalans were always devoid of body pigmentation, although they kept the red eye pigment undiluted in specimens fixed by formalin. The cirrus of T. lutzi showed the typical shape for the species, while the dorsolateral, post tentacular 'excretory' syncytial plates, demonstrated by two special techniques (silver nitrate staining and SEM), appeared with an elliptical shape and a central nephridiopore.

We also provide a new record for Miogryllus piracicabensis Piza, 1960 to the southern Brazil, improving calling song and karyotype information for this species. The type-material and vouchers are deposited in the Museu de Zoologia da Universidade de São Paulo (MZUSP).

Thirty-two specimens of Columbina picui (picui ground-dove) were examined, and a collection of arthropods was made by washing the external surface of the body and the nasal cavity. The species in the order Phthiraptera found and their respective prevalences, mean abundance and mean intensity were: Columbicola passerinae (84.4%; 10.3; 12.2), Hohorstiella passerinae (21.9%; 0.7; 3.1) and Physconelloides eurysema (3.1%; 0.1; 2). The gamasid mites found in the birds and their respective prevalences, mean abundance and mean intensity were: Pellonyssus marui (31.3%; 1.2; 3.9), Ornithonyssus bursa (15.6%; 0.2. ;1.2) and Mesonyssus sp. (6.3%; 0.1; 1). Columbicola passerinae, H. passerinae, P. eurysema, O. bursa, P. marui and Mesonyssus sp. were recorded for the first time infecting C. picui in Brazil. Except for O. bursa, the other species are reported for the first time in the state of Rio Grande do Sul, Brazil.

This research aims to verify the municipalities where it might be interesting to invest in a local beef production in the State of Rio Grande do Sul (RS), southern Brazil. The data analyzed combine the cattle units slaughtered and the estimated beef consumption in each municipality. These indicators were used to identify the capacity of each location to meet the local beef demand. This data were associated to the map of RS by the Quantum GIS 1.8 Lisboa software. The most prominent regions were located at the western frontier, at the southeast Campanha, and at the northeast mountain region of the State. The cattle units slaughtered produced at the municipalities of Aceguá, Pedras Altas, Machadinho, São Valentim, Quatro Irmãos and Sagrada Família is very high, surpassing the municipality’s capacity to absorb it. On the other hand, many municipalities have sufficient productions or little surplus to attend the local beef demand, such as Alegrete, in which a local beef production might benefit a higher number of small producers, but other municipalities also seem to have potential for assisting familiar farmers with this strategy such as Dom Pedrito, Bagé, Santa Maria and Pelotas.
