Abstract The presence of catfish of the Ariidae family in the list of endangered species of Rio Grande do Sul (RS), as from 2014, led to forbidding fishing two species of this family. Thus, artisanal fisherfolk lost a significant part of their income, causing conflicts between them and the fishing authorities in RS. This work aims mainly to understand the Local Ecological Knowledge (LEK) of the artisanal fisherfolk of the North Coast of RS regarding the ecology and taxonomy of catfish of the Ariidae family, seeking to relate it to the establishment of the fishing regulations in force in the State. 33 semi-structured interviews were made with artisanal fisherfolk. The interviewees perceive differences among the region ethnospecies; hardly ever are they consulted during the fishing regulations establishment process. Considering the aforementioned aspects, the artisanal fisherfolk LEK on catfish can be an important tool in the participatory management of catfish fishing.

The Impact

From the first cases of Covid-19 in Rio Grande do Sul, in March 2020, we started monitoring the pandemic using an online Geographic Information System (GIS). Within the SIG Litoral Project, from the Federal University of Rio Grande do Sul, we developed the platform as a strategy to provide society with spatial analysis and organized data on the disease, bringing together researchers, scholarship holders and volunteers. The portal, focused on health communication, allows the visualization of data on the global, national and regional scales, in addition to monitoring the indigenous populations of the Amazon and mapping the solidarity networks in the North Coast of Rio Grande do Sul. In the article in question, we mainly focus on monitoring Covid-19 in Rio Grande do Sul, addressing the tools used, the challenges to obtaining data and some spatial analysis performed. We show divergences between data sources, indicating the problem of underreporting and the different methodologies employed by health surveillance systems. Finally, we address the impact of the monitoring of Covid-19, having a positive impact on society by providing transparency to official data, contributing to the plurality of the debate, the interaction of multidisciplinary teams and the academic training of students.

Abstract Background The capture of ornamental fish is one of the main economic activities of riverine families in the Amazon. However, studies regarding the local ecological knowledge of workers in this activity are still incipient. In view of this, we have studied and explored the local ecological knowledge of artisanal fishers who specialize in the capture of fish for the aquarium trade in the middle part of the Negro River basin and investigated issues related to the ecological aspects of the fish species that are targeted by this trade in the region. Methods Therefore, we conducted semi-structured interviews and applied questionnaires to artisanal fishers of ornamental fish (N = 89), from the municipality of Barcelos, from January to April 2016. Results In total, 41 popular names were cited, which correspond to four ethnocategories and 10 families. The main species were Paracheirodon axelrodi (12.5%), Hemigrammus bleheri (8.3%), Ancistrus dolichopterus (6.4%), Symphysodon discus (5.3%), and Potamotrygon motoro (3.8%). According to the fishers, the species of fish known in the region as “piabas” have a preference for living in clusters (28.9%) and carry out migratory movements (26.1%). The diet of local fish species reported by fisheries is diverse, though mainly based on periphyton (42.2%), and the reproductive cycle directly influenced by the period of flooding of rivers in the region (37.6%) Conclusion Our study revealed that the fishers possess information on the ecological aspects of local ornamental fish species, many of which are consistent with scientific literature. The information presented may assist in the decision-making process for the management of local fishery resources and contribute to the resumption of growth and sustainability in the capture of ornamental fish.

ABSTRACT Ryegrass is a weed of annual cycle that is present in winter crops, in orchards and vineyards of the South region of Brazil. The species is normally controlled by the glyphosate herbicide, but the continuous use of this product caused the selection of resistant biotypes. The use of ACCase inhibitor herbicides is the main alternative for the control of this species, but it has not been satisfactory in some places, thus causing suspicion of resistance to this action mechanism. Thus, the objective of this paper was to evaluate the occurrence and geographic distribution of ryegrass biotypes that are resistant to the clethodim herbicide in the state of Rio Grande do Sul. For that, seeds of ryegrass plants that survived the application of clethodim were collected in crops from the north region of RS, summing up to a total of 152 samples from 72 cities. The biotypes were submitted to the application of 120 g i.a. ha-1 (maximum registered dose) and 60 g i.a. ha-1 de clethodim (half the maximum registered dose). According to the results, among the samples of ryegrass seeds collected, there were no biotypes resistant to the clethodim herbicide when the maximum registered dose was applied and in the stage of three to four leaves. However, there were biotypes with lower susceptibility that survived half the maximum registered dose.

Goliath Grouper

The goliath grouper Epinephelus itajara is a large sized (> 400 kg) and critically endangered marine fish, which is protected in many countries, including Brazil. Through the application of semi-structured interviews, we investigated the local ecological knowledge of seven fishermen specialist on catching E. itajara from the Babitonga bay, Santa Catarina, Brazil. Local long-line fisheries for E. itajara seemed to be a disappearing tradition in the studied site, with a detailed inherent local ecological knowledge system, which is also being lost. Our study also showed that fishermen engaged in recent fisheries, such as spear-fishing, can also possess a detailed local ecological knowledge system. Through the analysis of fishermen local ecological knowledge, several aspects of E. itajara life history were registered. This species is found in the inner and outer Babitonga bay, from saline waters to areas with a large input of freshwater, and inhabits submerged wooden substrates and artificial reefs such as shipwrecks, mooring pillars and cargo containers. It is known to spawn in December and subsequent summer months in the studied area. Spawning aggregations are usually seen in December (during full moon), being also eventually observed in January and February by our informants. While lobsters, spadefishes and octopuses seem to constitute the most important food items of inner bay E. itajara, outer bay individuals may feed on catfishes, crustaceans and other fish species. The goliath grouper is regarded as pacific and curious fish, but frequently display agonistic behavior in the presence of divers. Based on the perception of well experienced spear fishermen, we hypothesize that E. itajara undertakes seasonal migrations from the inner to the outer bay during summer, and that the studied population is suffering from growth over-fishing. Our data provides a practical evidence of how joining scientific and local ecological knowledge will likely benefit E. itajara local conservation and management practices by adding important new biological data into the decision-making process.

Introduction The city of Passo Fundo, in the north of the Rio Grande do Sul state, has been standing out in the health care field for many years. The state has become a reference in endovascular interventional neuroradiology. We will cover 10 years of experience in this area and divide our observations in 3 parts: cerebral angiograms (part I), carotid angioplasties (part II) and intracranial aneurysms (part III). The goal of part I is to statistically assess the cerebral angiograms, their indications, risks and complications, as well as to do a technical review. Materials and Methods A retrospective study from 2005 to 2015 with a total of 5,567 interventional neuroradiology procedures performed. A total of 4,114 angiograms, 639 embolizations of intracranial aneurysms, 414 carotid angioplasties, 143 embolizations of cerebral arteriovenous malformations, 32 embolizations of dural arteriovenous fistulas, 102 cerebral vasospasm treatments, 21 treatments of epistaxis, 36 embolizations of craniocervical tumor, 25 thrombolysis of ischemic stroke, 18 vertebroplasties and 13 embolizations of arteriovenous malformations of the face. Results A total of 4,084 procedures performed, 21,811 vessels studied, average vase 7.62/2.82 vessel and patient/procedure. Of these, 2,536 were diagnostic procedures and 1,548 angiographic controls. Of the total, 1,188 patients received only an angiogram, 27.14% of which were therapeutic procedures. We obtained a total of 3.89% complications: 2.33% reflection vasovagal, 0.56% allergic skin reaction, anaphylactic shock 0.07%, 0.27% femoral hematoma, 0.26% transient neurological deficit, 0.12% permanent neurological deficit and no case of death. Conclusion Cerebral angiography in adults, children and infants is a safe procedure with low risk of permanent neurological complications.

The purpose of this study is to explore how teenagers view the relationships and interactions in the process of healthily becoming an adolescent. This qualitative exploratory research was conducted with ten teenagers in a state college in a town in southern Rio Grande do Sul, Brazil, from August to October, 2007. We used semi-structured interviews to collect the data. Later, we decided to use a thematic analysis, in which two themes emerged: (1) the process of building relationships and interactions in adolescence and (2) the risk in social life. As a result, we realized the importance of interpersonal relationships formed in adolescence, which deserve the nurse’s attention. Nurses can help in the guiding of this population in basic health units, hospitals or schools, to a healthy adolescence. Thus, teenagers may enjoy the relationships built in this process in order to grow and to enter into adulthood.
