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.

Thus, recent study has shown that the response of species to environmental filters may differ in space, it depends on the observed scale and among the evaluated taxa. However, there is a gap in understanding the resources still contemplated to contemplate the different solutions observed. In this way, throughout the thesis we seek to contribute to the understanding of the groups involved in the assembly of communities on a global and local scale. For this, we carried out a macro-scale study evaluating how the contemporary climate and historical climate change determine the richness of tetrapod species. Through this study, we show that species characteristics are a strong mediator of the climate effect on species richness, but they are relevant in a different way for each of the metabolic and physiological singularities of these groups. Thus, we emphasize the importance of integrating the theory to understand the different bases developed. In the second chapter, we conducted a local experiment to understand how biological invasion and nutrient deposition affect communities, highlighting the role of trophic level in responding to the environment. Contrary to expectations, nutrient addition had no significant effect, while biological invasion emerged as a crucial factor, especially in the structure of predatory arthropod communities. We demonstrated that trophic interactions, including top-down and bottom-up control, are essential for understanding community responses to biological invasion. Therefore, in this thesis we highlight the mechanisms by which different environmental factors, on a global and local scale, determine community structure and highlight the role of species characteristics in determining the response of these communities.

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.

One is known as domestication of landscapes, which results in changes in the structure, composition and dynamics of terrestrial ecosystems. Several studies have documented how this process occurs in the tropical humid regions. However, little is known about how the process occurs in South American savannas, environments with specific dynamics and ecological patterns. In this study, we aim to elucidate temporal and spatial dimensions of the domestication process in typical tropical savanna landscapes. To achieve this goal we proposed a multifaceted strategy, using the following approaches: (1) a systematic review, which allowed us to know what are the management patterns of landscape units carried out by the people who inhabit the South American tropical savannas and how these strategies are related to different cultures and different landscapes; (2) an ethnoecological investigation in a Brazilian savanna region, Serra do Espinhaço (MG), using different participatory methods, which allowed us to understand how the apanhadores de sempre vivas manage the current landscapes and their perceptions of the consequences of the repression of their activities; and (3) temporal and spatial analyses to assess the changes in the landscapes in the traditional territory of the apanhadores de sempre vivas in the Serra do Espinhaço in the last two decades and their relationship with the presence and absence of traditional management, which allowed us to expose that after a period of strong repression of traditional management, driven by restrictive environmental policies, significant changes occurred in the landscapes and these brought ecological and social effects to the study region. With this, we discuss the importance of traditional management in structuring savannas landscapes and highlighted the need to recognize, resume and encourage traditional management for the conservation of South American savannas.
