Knowledge about mammals of the Atlantic Forest is still lacking, especially because some places remain poorly studied or inventoried, which makes conservation initiatives difficult. We aimed to determine the species richness and composition of medium and large sized mammals in a semideciduous forest remnant, Morro do Coco, thus contributing information about the occurrence of mammalian fauna in the metropolitan region of Porto Alegre, southern Brazil. The methods consisted of interviews with local inhabitants, visual records and sand plot analysis. The study took place from July 2008 to April 2009, with monthly expeditions of three days. Sixteen species of mammals were recorded, seven of which are threatened with extinction in Rio Grande do Sul and one nationally. The predominant trophic group was the frugivorous/herbivorous. The study area is situated in a prioritized zone for the conservation of mammals in Greater Porto Alegre, since it consists of one of the last remnants where the phytophysionomies that originally occupied the edge of Guaiba Lake and granite hills of the region are represented and preserved.

Mutation Spectra

Almost a year after the COVID-19 pandemic had begun, The United Kingdom, South Africa, and Brazil became the epicenter of new lineages, the Variant of Concern (VOCs), B.1.1.7, B.1.351, and P.1, respectively. These VOCs are increasingly associated with enhanced transmissibility, immunity evasion, and mortality. The previous most prevalent lineages in the state of Rio Grande do South (Brazil), B.1.1.28 and B.1.1.33 were rapidly replaced by P.1 and P.2, two B.1.1.28-derived lineages harboring the E484K mutation. To perform a genomic characterization of SARS-CoV-2 samples from COVID-19 patients from the metropolitan region of Porto Alegre (Rio Grande do Sul, Southern Brazil), in this second pandemic wave, we sequenced viral samples from patients of this region to: (i) identify the prevalence of SARS-CoV-2 lineages in the region, the state and bordering countries/states, (ii) characterize the mutation spectra, and (iii) hypothesize possible viral dispersal routes by using phylogenetic and phylogeographic approaches. As results, we not only confirmed that 96.4% of the samples belonged to the P.1 lineage but also that approximately 20% of which could be assigned as the newer P.1.2 (a P.1 derived new sublineage harboring new signature substitutions recently described and present in other Brazilian states and foreign countries). Moreover, P.1 sequences from this study were allocated in several distinct branches (four clades and five clusters) of the P.1 phylogeny, suggesting multiple introductions of P.1 in Rio Grande do Sul still in 2020 and placing this state as a potential core of diffusion and emergence of P.1-derived clades. It is still uncertain if the emergence of P.1.2 and other P.1 clades are related to further virological, clinical, or epidemiological consequences. However, the clear signs of viral molecular diversification from recently introduced P.1 warrant further genomic surveillance.

Ditaxodon taeniatus is a striped, racer-like colubrid snake inhabiting grassland savannas in southern Brazil. This species was described as Philodryas taeniatus by the then curator of the Museum für Naturkunde der Humboldt-Universität zu Berlin (formerly Zoologisches Museum Berlin, ZMB), Wilhelm Peters, from a single specimen collected by Reinhold Hensel in Porto Alegre, Rio Grande do Sul. Peters’ description was published in a paper by Hensel (1868: 331) and, according to the International Code of Zoological Nomenclature (ICZN, 1999: Article 50.1, Recommendation 51E), the correct citation is Ditaxodon taeniatus (Peters in Hensel, 1868). Later, George A. Boulenger (1896: 124) transferred Philodryas taeniatus to the genus Conophis, and Alphonse R. Hoge (1958: 54) created for it the new genus Ditaxodon, which remains monotypic today.

Specific and efficient methods for capturing tinamous are scarce in the scientific literature. Here we tested the effectivity of two methods for capturing the Yellow-legged Tinamou Crypturellus noctivagus (Tinamidae): a bell-trap adapted with a nylon cast net and a type of fall-trap. In a forest remnant in Rio Grande do Sul state, Brazil, we applied 120 hours of sampling effort using the traps, resulting in the capture of six individuals (two females and four males). These capture methods are an efficient tools and useful for forest tinamous studies, although it can be also used for capturing other forest bird which use the forest floor.

Nigrohydnum nigrum Ryvarden is a rare polypore previously known only from two records in Brazil. During a herbarium revision at SP we have identified an old voucher specimen, extending the previously known geographic distribution to the Atlantic rain forest of Porto Alegre, Rio Grande do Sul State, Southern Brazil.

And Training

On September 20, 1835, borderland chieftains and their followers in Rio Grande do Sul, known as Farrapos or Ragamuffins, toppled the provincial government in Pôrto Alegre. By November 1836 the Farrapos had established a republican government in the small town of Piratini in the southwest hills of the province; for close to ten years they would withstand the power of the Brazilian Empire in their bid for independence. At the outset, when the rebels had captured the initiative, they were reluctant to use slaves in the Ragamuffin army. Aware of internal security problems and the sanctity of private propetry, the leadership expressed fear of arming and training Afro-Brazilians. But as the maddening horse-war dragged on, the newly created Republic of Rio Grande do Sul became eager for men who might be counted as white. By the end of the Ragamuffin War, slaves were the backbone of the rebel army.

Este artigo se propõe a refletir sobre o significado do aprendizado da informática para um grupo de idosos participantes de um programa social de uma universidade, situada na região metropolitana de Porto Alegre, Rio Grande do Sul. Por meio de entrevistas, análise de conteúdo e com o auxilio de um referencial teórico de abordagem biopsicossocial, observamos que o curso representa principalmente a necessidade de exercitar a autonomia pessoal, com o uso do computador. Refletimos ainda que o fato de o idoso estar em grupo, nesse processo de aprendizagem, contribui, segundo eles, para a compreensão e aceitação do processo de envelhecimento humano.palavras-chave Envelhecimento Humano.

The African spider Cithaeron reimoseri Platnick, 1991 is registered for the first time in the New World, based in two females collected at Porto Alegre, Rio Grande do Sul, Brazil. Until now C. reimoseri was known only by the holotype from Eritrea. The species C. praedonius O. P.-Cambridge, 1872 was, until now, the only known species of the family with worldwide distribution and is considered prone to introduction in anthropic environments. Cithaeronidae are considered lower gnaphosoids being identifiable by the depressed posterior median eyes and the pseudosegmented tarsi.

The parasitic copepod Gauchergasilus euripedesi (Montú, 1980) Montú & Boxshall, 2002 was described from plankton samples and specimens found in four fish species from the estuarine area of Patos Lagoon, state of Rio Grande do Sul (RS), Brazil. Later, one different fish species was reported parasitized with G. euripedesi in the same locality. Species of Astyanax Baird & Girard, 1854 (Astyanax henseli Melo & Buckup, 2006 and Astyanax lacustris (Lütken, 1875)) and Psalidodon Eigenmann, 1911 (Psalidodon eigenmanniorum (Cope, 1894) and Psalidodon aff. fasciatus (Cuvier, 1819)) were collected in two environments (Pintada Island, municipality of Porto Alegre and Itapeva Lagoon, municipality of Terra de Areia, RS) to investigate their parasites. The copepods found in the gill arches were counted, processed, mounted in permanent slides, and photographed using light microscopy, or processed for observation in scanning electron microscopy. Specimens of P. eigenmanniorum from Pintada Island, A. lacustris and P. aff. fasciatus from Itapeva Lagoon, were parasitized by G. euripedesi, with prevalences of 29.03% (A. lacustris), 10.34% (P. eigenmanniorum), and 9.68% (P. aff. fasciatus). Measurements obtained for specimens of G. euripedesi were similar to those found in the literature, except for egg sacs which were larger in the specimens examined in the present study. In addition to being the first report of G. euripedesi parasitizing species of fish (A. lacustris, P. eigenmanniorum, and P. aff. fasciatus), the results presented here also extend the known geographic distribution of the copepod species.
