In light of this scenario, it becomes essential to understand whether the population is truly interested in and engaged with the issue, that is, whether there is awareness and concern about the consequences of climate change. This interest is considered one of the main triggers for promoting behavioral change, both at the individual and collective levels. In this study, we investigate the degree of public interest in climate change among Brazilians and the factors that influence this interest. To do so, we use Relative Search Volumes (RSVs) for climate-related topics, extracted from the Google Trends tool, provided by the world’s largest search engine platform. This tool allows us to identify temporal trends and spatial variations in interest, including among different Brazilian states. Based on this data, we analyze whether interest in climate change varies according to sociodemographic factors (such as the Human Development Index — HDI, the Gini index, and the political leaning of the states) or in response to relevant historical events (such as the occurrence of extreme weather events, the release of IPCC reports, and the holding of the Conferences of the Parties — COPs). Our results indicate that states with lower HDI and higher Gini inequality values show greater interest in the topic, suggesting that populations more socioeconomically vulnerable, and therefore more exposed to the impacts of climate change, are more engaged in seeking information on the subject. The results regarding interest based on political leaning suggest that, in Brazil, the climate crisis is not a highly politically polarized issue. Furthermore, we found that interest increases significantly after the release of the IPCC reports, suggesting that Brazilians, in general, are interested in scientific information about climate. In contrast, no increase in interest was detected in connection with the COPs or media coverage of extreme climate events, which may indicate the limited effectiveness of these instances in promoting lasting awareness among the Brazilian public.

Although the different subjects of communication are widely recognized, presented, and discussed within social and discourse theories, little is known about the role of narrative presentations in establishing the social modus operandi. In this way, the scenario of disinformation and denialism emerges as an important threat to the establishment of a discourse based on science and to how populations perceive and respond to different risks, such as climate change. An innovative approach to addressing this dilemma must incorporate broad data on the risk perception of Brazilians as well as socioeconomic information, a gap that this work aims to address. For this purpose, we evaluated secondary data on the concern of Brazilians about climate change during the years 2020 to 2022. Working with a solid database, we sought to understand how political stance and exposure to disinformation affect climate concern under a quantitative parameter by creating indices that serve as variables of interest for analyses through cumulative link models. Our results revealed that the consumption of climate information is crucial for increasing concern about the topic and also showed that political stance is a key factor to consider when analyzing climate perception variables. Therefore, it is extremely important to develop communication strategies that consider the different nuances of Brazilians' climate concern to combat the effects of disinformation and climate denialism because the dissemination of misleading content can be extremely harmful and directly influence public decision-making based on false information, aggravating the situation of communities already suffering from the consequences of climate change.

With that in mind, we aimed to access the LEK on the behavioral ecology of mammals, verifying its convergences and divergences with scientific knowledge. Considering that some factors can influence the LEK, we expected that contact with nature will influence the LEK about the behavioral ecology, as well as we expect that people will know more about conspicuous behavior. The study was carried out in the district of Ribeira (Cabaceira-PB). Data collection was divided into two stages: (1) free list (92 respondents) and (2) interview on the behavioral ecology of mammals mentioned in the free list (150 respondents). To assess the convergences between the LEK and the scientific knowledge, we compared literature information with the LEK. The forms of contact with nature were: (1) time of residence, (2) occupation, (3) age and (4) frequency of encounters with the species. Behavioral characteristics were classified into: (1) conspicuous behaviors; (2) cryptic behaviors. We verified that people who carry out rural activities, live longer in the region and encounter animals more frequently have a higher LEK. We also saw that people are better aware of the conspicuous behaviors of species when compared to cryptic behaviors. Regarding conspicuous behaviors, the data show, for the most part, convergence between the two types of knowledge. In this sense, our findings provide strong arguments for the use of Local Ecological Knowledge as a tool for behavioral ecology. Thus, this study can help behavioral ecology researchers to consider LEK as an efficient method of accessing information about species. We also highlight the importance of keeping both knowledge systems as a separate source of information, considering LEK as a complement to scientific knowledge that allows a better understanding of the behavioral ecology of species.

There is a need to integrate traditional peoples' knowledge into management practices, to understand how they perceive environmental risks and their adaptive coping strategies. Some socioeconomic factors can influence the way in which individuals perceive risks and elaborate adaptative strategies with the active participation of the local population. Thus, our research aimed to understand: i). What is the relationship between socioeconomic factors and risk perception in a population of artisanal fishers and ii). If they perceive adaptative coping strategies carried out in a participatory manner. We will deal here with risks to the environmental quality of the Rio Formoso estuary, state of Pernambuco. Individual interviews were carried out with 102 fishers, 54 men and 48 women, who freely listed and described the risks to the conservation of estuarine ecosystems. Our analysis is divided into three parts: i) Cognitive Salience Index (CSI); ii) Hypothesis test of the number of perceived risks; and iii) Perception network between risks and strategies. We identified 22 risks and categorized them into five major groups: i) Fishing; ii) Boat’s flow; iii) Continental pollution; iv) Urban development; and v) Others. In general, the perception of environmental risks by fishers was mainly related to continental pollution and fishing activity, while the increase in formal education (the most relevant factor) and the presence of complementary income positively affected the number of perceived risks. Another factor is the influence of sex on this perception: men identified more risks than women. We identified 13 adaptative strategies. We categorized seven of them as “governmental” (exclusive responsibility of the municipal, state and / or federal public management) and the other six as “participatory” (performed with some or total participation of residents). We found that the more salient the risk, the greater the number of strategies mentioned by fishers. In our analysis of the perception network, we found three risk modules more related with participatory strategies, involving residents, public management, and universities. This fact exposes a favorable scenario for increasing the active involvement of scientists through their research, extension projects and participation in collectives movements and NGOs in searching for joint solutions with the populations for these environmental problems. We emphasize the importance of understanding context-specific socioeconomic factors and identifying participatory strategies for promoting biocultural conservation in socio-ecological systems of artisanal fishing populations in tropical areas. We suggest deepening future research on questions about how formal and non-formal education, sex, and supplementary income qualitatively affect the perception of risk.
