Studies based on the relationship between humans and the natural environment have been proven to be important tools for understanding the influence, knowledge, and perceptions associated with the web of interactions between humans, species and ecosystems. Here, we highlight the interactions between cetaceans and artisanal fishing. Thus, this study aimed to: a) compile studies that consider artisanal fishing and its interactions with small cetaceans in Brazil; b) understand research trends over the years; c) analyse the distribution of studies by country region; d) perform authorship and citation analyses; e) classify the interactions between cetaceans and artisanal fishing recorded by authors and f) identify dolphin species registered in the study. To achieve this, we reviewed the current status of national publications related to the interactions of cetaceans (suborder Odontoceti) with artisanal fishing in Brazil, focusing on ethnoecological studies. Seven databases were used to survey the studies. To classify the interactions, we adopted the categorization proposed by Freitas-Netto and adapted by Di Beneditto. Based on the data analysis, we registered 12 types of interactions, seven of which were grouped according to the descriptions proposed by Di Beneditto and five new categories were described based on the results of this study. The studies reported the interaction of 43.2% (n=16) of the 37 odontocete species reported to occur in Brazil, with emphasis on the species Sotalia guianensis, Tursiops truncatus, Pontoporia blainvillei, Inia geoffrensis and Sotalia fluviatilis. From our research it was possible to observe that ethnoecological studies allow us to answer important questions about the occurrence of species and aspects of fishing. Furthermore, we reinforce the importance of developing studies which focus on the knowledge of the existing relationships between cetaceans and traditional fishing methods, since studies on this topic can generate data that contribute to the establishment of mitigation strategies and the management of species and ecosystems.

Road infrastructure has caused severe impacts on the environment and wildlife. Understanding and mitigating these effects are essential conservation measures. This study aimed to evaluate wildlife mortality due to animal-vehicle collisions along an 80-km stretch of the Tapir Rocha Highway (RS–040). The field inventory was carried out between August 2015 and March 2019. Once a week, two observers drove along the highway at an average speed of 40 km/h and all the vertebrate roadkill spotted from the car were assessed to record the species, carcass condition, and the roadkill locations along the road. In total, 2,371 dead animals were recorded and categorized into 137 species. The most affected classes were mammals (n = 1,223), and birds (n = 704). The most affected wild species were white-eared opossums (Didelphis albiventris, n = 559), black-and-white tegus (Salvator merianae, n = 129), and coypus (Myocastor coypus, n = 102). Carcass exposure assessments indicated that many (n = 637) of the animal deaths occurred the night before our arrival, which may suggest that nocturnal species were among the most vulnerable to mortality. Roadkill sighting peaked in the spring (34%) and summer (25%), probably due to reproductive activity and juvenile dispersal. Evident seasonal variations included a 50% reduction in reptile roadkill rates in autumn-winter compared to spring-summer, and a 20-percentage-point increase in the number of mammal road deaths in the winter. The reduced activity that reptiles display at low temperatures, and seasonal changes in carnivore food habits may explain these respective findings. While most of the animal victims of roadkill were common and widely distributed species with abundant populations, decreasing abundance of these species is a growing conservation concern.

The current investigation aimed to identify the wild animals utilized as a food source in five locations within the Serra do Conduru State Park region, Bahia, Brazil. The field survey was conducted from June 2016 to July 2017, involving semi-structured interviews and informal conversations with 45 hunters. The composition of species used for sustenance in the five locations was characterized through permutation multivariate analyses of variance. Generalized linear models were constructed to evaluate whether socio-demographic variables among hunters influenced the number of captured species. A total of 67 species (34 families and 22 orders) of hunting significance were documented in the region, with 41 being hunted for consumption. The most represented taxa were mammals (32), birds (21), reptiles (13), and amphibians (1). Dicotyles tajacu, Dasypus novemcinctus, and Cuniculus paca emerged as the most targeted species for food. Hunters who still reside within the conservation unit capture a greater number of wild animals. Older hunters and those with smaller family sizes hunt a broader range of species. The rifle and domestic dogs are the predominant techniques employed in the region. The findings underscore the persistence of illegal hunting practices in the Serra do Conduru State Park region. This emphasizes the necessity for measures directed at the conservation of hunted species, particularly those identified as being under some degree of threat in nature.

This study aimed to investigate the relationship between the imaginary of Caipora and environmental conservation in Serra da Jiboia. Data obtained through the application of semi-structured interviews and Likert scale. All data were analyzed qualitatively and quantitatively. Through factor analysis, it was possible to identify four factors that explain the variations in responses given by residents of the region, suggesting a strong belief in the spiritual entities of the forest and its importance for nature conservation. 57 interviews were carried out and the socioeconomic characterization of the participants was carried out, were composed of men and women predominantly between 50 years or more and who carry out agricultural activities. Although Catholicism is the predominant religion in the region, belief in Caipora was high, being related to the appreciation and preservation of local nature. Through the chi-square test, it was possible to verify a statistically significant relationship between the belief in Caipora and the activities carried out in the forest by the interviewees. This study contributes to the understanding of the relationship between popular beliefs and environmental conservation, highlighting the importance of considering local knowledge for the development of public policies aimed at nature preservation.

We propose to investigate if the use and knowledge of medicinal plants and alternative medicine influence the adoption of biomedical strategies in dealing with COVID-19 - such as the use of masks, social isolation, and vaccination - in a context of a neo-rural population. We collected data through online questionnaires, using the Google Forms platform in the “Paravachasca Valley”, Córdoba, Argentine. The questionnaires, anonymous, contained multiple choice questions about attitudes and opinions concerning prophylactic strategies against COVID-19. To test whether the use or knowledge of medicinal plants is associated with trust in the efficiency and adoption of biomedical strategies, we used a chi-square test of independence. We saw that this neo-rural population does not differ from urban populations in terms of the proportion of people who deny biomedical strategies to prevent COVID-19. Furthermore, we verified that the knowledge about medicinal plants is related to distrust and reluctance to the adoption of the use of masks, social isolation, and vaccination. Also, our results suggest that alternative medicine users are afraid of the vaccine effects. In this plural medical context of a neo-rural population, belief in alternative medicines for the treatment of COVID-19 can be an obstacle to immunization programs.

In this study, we sought to examine firewood use patterns in artisanal ceramic production by a quilombola community in the context of forest scarcity in Northeastern Brazil. This article aimed to answer the following questions: (1) Is the firing of ceramic products related to the perceived quality, diversity, or plant part used as firewood? (2) Does the diversity of plants used as firewood vary according to the age and gender of artisan potters? (3) What are the physical and energetic properties of the species most commonly used as firewood? Our main findings were that resource availability and accessibility seem to be the determining factors of firewood use. Exotic species were widely used. Variables commonly described as predictors of firewood diversity, such as age and gender, were not relevant in the context of forest scarcity. The most used exotic species have good physicochemical properties and can be a viable alternative to meet the firewood demand of ceramic production. However, the results showed that these species are more readily available to potters who have access to private woodlands. Therefore, in the studied context, we suggest the need for conservation strategies that foster the creation of energy forests composed of exotic species and, in parallel, promote conservation and reforestation actions aimed at native species.
