Introduction
Covering 200,000 km2, the Brazilian Pantanal wetland is a major stronghold for the Near Threatened jaguar Panthera onca (Caso et al., Reference Caso, Lopez-Gonzalez, Payan, Eizirik, de Oliveira and Leite-Pitman2008) in the Americas (Zimmermann et al., Reference Zimmermann, Walpole and Leader-Williams2005) and, currently, the species is heterogeneously distributed in 63% of this biome (Cavalcanti et al., Reference Cavalcanti, de Azevedo, Tomás, Boulhosa and Crawshaw2012). However, in the Pantanal most of the jaguar population lives outside protected areas as 95% of this biome consists of private lands (Crawshaw & Quigley, Reference Crawshaw and Quigley1991; Seidl et al., Reference Seidl, Silva and Moraes2001) where the main economic activity is extensive cattle ranching (Seidl et al., Reference Seidl, Silva and Moraes2001; Cavalcanti & Gese, Reference Cavalcanti and Gese2010). Jaguars have coexisted with humans and their livestock for nearly 200 years in the Pantanal (Crawshaw & Quigley, Reference Crawshaw and Quigley1991; Cavalcanti & Gese, Reference Cavalcanti and Gese2010) and livestock predation is considered one of the main causes of people's intolerance towards this species (Zimmermann et al., Reference Zimmermann, Walpole and Leader-Williams2005; Cavalcanti et al., Reference Cavalcanti, de Azevedo, Tomás, Boulhosa and Crawshaw2012).
Although the jaguar has been well studied in the Pantanal (Schaller & Crawshaw, Reference Schaller and Crawshaw1980; Crawshaw & Quigley, Reference Crawshaw and Quigley1991, Reference Crawshaw, Quigley, Medellin, Chetkiewicz, Rabinowitz, Redford, Robinson, Sanderson and Taber2002; Dalponte, Reference Dalponte, Medellin, Chetkiewicz, Rabinowitz, Redford, Robinson, Sanderson and Taber2002; Soisalo & Cavalcanti, Reference Soisalo and Cavalcanti2006; de Azevedo & Murray, Reference de Azevedo and Murray2007; Cavalcanti & Gese, Reference Cavalcanti and Gese2010; Cavalcanti et al., Reference Cavalcanti, de Azevedo, Tomás, Boulhosa and Crawshaw2012), little is known about people's perceptions and attitudes towards this felid. The information available mostly concerns the conflict between ranchers and jaguars as a result of livestock depredation (Zimmermann et al., Reference Zimmermann, Walpole and Leader-Williams2005; Santos et al., Reference Santos, Jácomo and Silveira2008; Marchini & Macdonald, Reference Marchini and Macdonald2012). No information exists on the relationship between the jaguar and the traditional communities that live along the main rivers of the Pantanal (the Paraguai, Taquari and Cuiabá) where people subsist mainly on fishing.
Large predators are perceived negatively because people fear being attacked or having livestock predated (Campbell & Alvarado, Reference Campbell and Alvarado2011; Soto-Shoender & Main, Reference Soto-Shoender and Main2013), and this may be an important component in the socio-economic and environmental contexts of the conservation of the jaguar. In this study we evaluate perceptions of the jaguar among adults in riverside communities along the Paraguai River, from Corumbá to Pantanal Matogrossense National Park. As better informed people tend to fear the jaguar less (Cavalcanti et al., Reference Cavalcanti, Marchini, Zimmermann, Gese, Macdonald, Macdonald and Loveridge2010), we sought to answer the following questions: (1) is the perception of the jaguar related to people's level of education and age, and (2) are the perceptions of local riverside people different from those of rural-dwellers whose main activity is cattle ranching, and inhabitants of other Brazilian biomes?
Study area
The study was carried out during April–June 2011 along c. 400 km of the Paraguai River from Corumbá to Pantanal Matogrossense National Park. This area encompasses the only federally-protected area within the Pantanal and is close to the Amolar mountain ridge (a poorly-known area considered important for biodiversity conservation; MMA, 2007).
The Paraguai River is the main drainage channel of the Pantanal (Calheiros & Ferreira, Reference Calheiros and Ferreira1997), flowing 2,621 km north to south, with 1,693 km lying in Brazil (Innocencio, Reference Innocencio1977). The predominant vegetation along the river is gallery forest, which in the most elevated areas is not influenced by the seasonal floods that occur in the Pantanal (Pott, Reference Pott1982), and flooded fields comprising native grasses (da Silva et al., Reference Da Silva, Mauro, Mourão and Coutinho2000). The climate is warm, with a dry winter season (Köppen's Aw seasonal regime: tropical wet and dry or savannah climate; Cadavid-Garcia, Reference Cadavid Garcia1984). Annual rainfall is 800–1,400 mm, of which almost 80% falls during November–March (da Silva et al., Reference Da Silva, Mauro, Mourão and Coutinho2000).
The main economic activities along the Paraguai River are recreational and professional fishing (Franco et al., Reference Franco, Drummond, Gentile and Azevedo2013). Cattle-ranching is limited because of seasonal flooding and the small size of riverside properties. Although low in density, several communities occupy the river margins, of which Castelo, Paraguai Mirim, Amolar and Barra do São Lourenço are the most populated. Together, these communities comprise c. 70 extended families, distributed along c. 400 km of the Paraguai River (Instituto Homem Pantaneiro, unpubl. data).
Methods
We interviewed riverside communities, using a semi-structured questionnaire accompanied by a picture of a jaguar (Conforti & de Azevedo, Reference Conforti and de Azevedo2003; Marker et al., Reference Marker, Mills and Macdonald2003; Santos et al., Reference Santos, Jácomo and Silveira2008). We travelled by boat, stopping at residences located along the riverbank and, randomly, at residences located in Castelo, Paraguai Mirim, Amolar and Barra do São Lourenço (Fig. 1). On some occasions we interviewed more than one person from the same family but these interviews were at the same time and the interviewees were separated from each other to avoid bias. The questionnaire comprised open and closed questions to gather information about the interviewee and their perceptions of jaguars, following Santos et al. (Reference Santos, Jácomo and Silveira2008).

To profile the interviewees we asked for their age, gender, birthplace, time living in the region, profession and level of education. To determine perceptions of the jaguar, we asked three questions: (1) have you ever seen a jaguar? (2) where did you see a jaguar? and (3) what do you think of the jaguar? The first question allowed us to evaluate whether the species is recognizable. Responses to the third question established perceptions of the jaguar, with respondents given the possibility of answering dangerous (i.e. a threat to human life), beautiful or both beautiful and dangerous, which was interpreted as a neutral response (Santos et al., Reference Santos, Jácomo and Silveira2008).
A further two questions concerned the values that people attribute to the jaguar: (4) do you think the jaguar should be eliminated from nature? and (5) why? Interviewees could justify either elimination or protection of jaguars (Santos et al., Reference Santos, Jácomo and Silveira2008). Responses to these two questions revealed the values associated with jaguars, which were categorized (as in Santos et al., Reference Santos, Jácomo and Silveira2008) as: (1) anthropocentric, demonstrating a desire to conserve the jaguar for future generations or believing that the species should be allowed to persist if it does not pose risks to humans; (2) religious, viewing the jaguar as a religious icon; (3) economic, related to economic losses from livestock predation; (4) moral, as jaguars are protected by Brazilian law; or (5) ecological, recognizing the ecological role of the species. Additionally, during interviews, we collected information about the occurrence of jaguar attacks on people in the region.
Analyses were conducted using R v. 2.15.3 (R Development Core Team, 2009). To test the effect of educational level and age of interviewees we used a General Linear Mixed Model (GLMM). Perceptions were inferred to be positive when the respondent answered ‘no’ to question (4) (=1), and negative when the answer was yes (=0). Educational level was converted to a numeric variable on the scale 1–6: 1, illiterate; 2, incomplete fundamental school (i.e. elementary school); 3, complete fundamental school; 4, complete medium school (i.e. high school); 5, incomplete undergraduate (tertiary education); 6, complete undergraduate. The Akaike information criterion (AIC; Akaike, Reference Akaike1974) was used to evaluate the best model. A χ2 test was used to compare the perceptions (beautiful, dangerous, beautiful and dangerous) and values attributed to the jaguar. These data were also compared to those of inhabitants of rural properties and other Brazilian biomes (Amazon forest, Cerrado, Caatinga and Atlantic Forest), using data from Santos et al. (Reference Santos, Jácomo and Silveira2008).
Results
We carried out 50 interviews with local people along the Paraguai River, of which 78% were men (n = 39) and 22% were women (n = 11). Fifty-eight per cent of the interviewees were 20–59 years old, 32% ≥ 60 years old, and 10% 15–19 years. Most of the riverside inhabitants were born in towns in the Pantanal (84% in Corumbá, Poconé, Miranda or Barão do Melgaço), and 14% were born along the Paraguai River. Only one foreigner (from Germany), who had been living in the region for > 20 years, was interviewed.
Illiteracy was the most frequent level of education (40%), followed by incomplete Fundamental School (36%). Only 10% of the interviewees had completed Fundamental School and fewer had completed Medium School (8%). One interviewee had completed tertiary education and another was still studying at the tertiary level.
Subsistence agriculture combined with small-scale cattle ranching were the main professions of the interviewees (24%), followed by professional fishing, cattle ranching only, housekeeping, property management, cowboy, subsistence agriculture only, live bait collection or boat captain. All of the interviewees confirmed using fish resources from the river as a complementary food source.
All interviewees recognized the jaguar, and 92% stated that they had seen one in its natural environment. The remainder recognized jaguars from photos, skins or tracks. ‘Dangerous’ accounted for 48% of the responses to the question on perceptions, followed by ‘dangerous and beautiful' (28%). ‘Beautiful’ was the least cited perception of the jaguar. Perceptions differed significantly between riverside people, local people that live on cattle ranches in the Pantanal and inhabitants of other Brazilian biomes (χ2 = 102.349, df = 10, P < 0.001), with a higher proportion of riverside people perceiving the jaguar as dangerous (Table 1).
Perceptions of the jaguar Panthera onca (as % of respondents in each study) by riverside inhabitants (n = 50) interviewed in 2011 along the Paraguai River in the Brazilian Pantanal (this study; Fig. 1), by local inhabitants on rural properties in the Miranda subregion of the Pantanal (n = 200), and by inhabitants of four other Brazilian biomes (n = 200; data from Santos et al., Reference Santos, Jácomo and Silveira2008, for both latter groups).
Age and educational level appeared to influence perceptions of the jaguar along the Paraguai River. Based on the GLMM analysis, the best explanatory model was age + school (Table 2). Older people tended to have negative perceptions about the jaguar (P < 0.01), whereas those with a higher level of education tended to have more positive perceptions of the species (P < 0.05).
General Linear Mixed Model examining factors influencing perceptions of the the jaguar, with the respective β coefficients (Age and School), by people living along the Paraguai River (Fig. 1). Models are ordered by rank according to their ΔAIC and weighting (wAIC).
Although responses indicated that the jaguar is perceived as a dangerous animal that can kill a person or cause damage to livestock, 66% of interviewees felt that the jaguar should not be eliminated from nature. The values associated with the jaguar by riverside inhabitants differed significantly from those of local people from ranches and from other Brazilian biomes (χ2 = 201.145, df = 20, P < 0.001; Table 3). The predominant reasoning for this was anthropocentric (i.e. protection for future generations), followed by economic and ecological considerations. Three cases of non-fatal jaguar attacks on people were reported by the interviewees in the last 10 years in the region of the Paraguai River.
Values attributed to the jaguar (as % of respondents in each study) by riverside inhabitants (n = 50; this study) interviewed along the Paraguai River (Fig. 1), by inhabitants of rural properties in the Miranda subregion of the Pantanal (n = 200), and by inhabitants of four other Brazilian biomes (n = 200; data from Santos et al., Reference Santos, Jácomo and Silveira2008 for both latter groups).
Discussion
The conflict between ranchers and jaguars in the Pantanal is well documented and is typically associated with livestock depredation (Zimmermann et al., Reference Zimmermann, Walpole and Leader-Williams2005; Silveira et al., Reference Silveira, Boulhosa, Astete and Jácomo2008; Cavalcanti & Gese, Reference Cavalcanti and Gese2010; Marchini & Macdonald, Reference Marchini and Macdonald2012), as occurs elsewhere where domestic livestock coexist with carnivores (Mizutami, Reference Mizutami1999; Butler, Reference Butler2000; Patterson et al., Reference Patterson, Kasiki, Selempo and Kays2004; Rigg et al., Reference Rigg, Findo, Wechselberger, Gorman, Sillero-Zubiri and Macdonald2011). However, this association is not relevant to riverside communities, where cattle ranching is not the main activity. Because of their dependency on river and forest resources such as fish, bait, water, firewood and natural medicines, riverside people are in direct contact with jaguars, which prefer forest habitats proximal to water (Crawshaw & Quigley, Reference Crawshaw and Quigley1991). Thus, it is not surprising that 92% of the people interviewed had seen a jaguar in its natural habitat. Of the 200 people in the Pantanal interviewed by Santos et al. (Reference Santos, Jácomo and Silveira2008), in Miranda and Aquidauana, 78% stated that they had seen a jaguar in its natural environment.
We noted from our interviews that although people viewed the jaguar as a dangerous animal and highlighted the risks to humans, they did not think that the species should be eliminated. We link this to the high incidence of anthropocentric values attributed to the jaguar (riverside communities want future generations to know the species and enjoy its beauty, although they are afraid of the risks it poses to them). The negative perceptions of riverside communities are related to concern for people's safety, whereas for ranchers and local people from rural properties they are predominantly related to the economic damage that the species can cause (although both latter groups also expressed a desire to protect the jaguar; Zimmermann et al., Reference Zimmermann, Walpole and Leader-Williams2005; Santos et al., Reference Santos, Jácomo and Silveira2008).
Interviewees highlighted their increased vulnerability to attacks during the wet season, when residences are surrounded by water, forcing inhabitants to move to higher areas that are also favoured by jaguars. This has occurred almost every year since the extensive flood of 1974, which completely changed the environment and socio-economic context of the region as riverside inhabitants could no longer work in the flooded cattle ranches (Franco et al., Reference Franco, Drummond, Gentile and Azevedo2013). Extensive flooding is the major ecological driver in the Pantanal and for most terrestrial mammals, including the jaguar, flooding drastically reduces the area available for foraging (Crawshaw & Quigley, Reference Crawshaw and Quigley1991), making predatory attacks on livestock more frequent when wild prey are not available, as informally reported during the interviews. Therefore, although cattle ranching is not a crucial activity to the interviewees, losses caused by livestock predation still shape perceptions. Similarly, news of jaguar attacks on people spreads quickly, possibly increasing fear and negative perceptions of the jaguar. Three cases of non-fatal jaguar attacks were reported by the interviewees, two (one fatal) were cited by Campos Neto et al. (Reference Campos Neto, Garrone Neto and Haddad2011), and a further two were reported during 2013–2014 (G. Porfirio, pers. obs.).
Although jaguars are potentially dangerous to people (Marchini & Macdonald, Reference Marchini and Macdonald2012), according to Cavalcanti et al. (Reference Cavalcanti, Marchini, Zimmermann, Gese, Macdonald, Macdonald and Loveridge2010) fear of this species varies depending on people's knowledge. As highlighted by Santos et al. (Reference Santos, Jácomo and Silveira2008), several studies have proposed environmental education as a tool for mitigating conflict between people and wildlife. Some educational material on coexistence between predators and domestic animals is available (e.g. Marchini & Luciano, Reference Marchini and Luciano2008; Marchini et al., Reference Marchini, Cavalcanti and de Paula2011). The use of this kind of material, especially in schools located along the Paraguai River, should be promoted, especially as environmental awareness seems to translate more easily into behaviour amongst young students (Carvalho, Reference Carvalho2001; Lucherini & Merino, Reference Lucherini and Merino2008). The presence of parents at environmental education events in schools could also contribute to awareness in the medium- to long-term, thereby helping to foster a healthier coexistence with jaguars (Damerell et al., Reference Damerell, Howe and Milner-Gulland2013). As it has been suggested there is a link between knowledge and positive attitudes towards animals (Cavalcanti et al., Reference Cavalcanti, Marchini, Zimmermann, Gese, Macdonald, Macdonald and Loveridge2010; Torkar et al., Reference Torkar, Mohar, Gregorc, Nekrep and Adamič2010), changes in attitudes could be achieved and attenuated, independently of age or educational level. This could be the most efficient and cost-effective way to work with adults along the Paraguai River, as communities and houses are located far from each other, hindering access. Nevertheless, there are also other strategies, such as ecotourism and improvement of management to minimize livestock predation (Marchini et al., Reference Marchini, Cavalcanti and de Paula2011), to help protect the species (Loveridge et al., Reference Loveridge, Wang, Frank, Seindensticker, Macdonald and Loveridge2010) and to shape more positive perceptions of the jaguar.
We believe that the feeling of local people living along the Paraguai River that the jaguar needs to be protected is derived from changes in tourism. Even though the main tourism-related activity in the region is recreational fishing rather than ecotourism, there are several cases where people have spent > 1 hour observing a jaguar on the riverbank (e.g. at Porto Joffre; G. Porfirio, pers. obs.). Jaguar observation needs, however, to be regulated, to limit the risks to both people and jaguars. Currently, only Mato Grosso state in Brazil has a specific law to deal with jaguar observation by tourists, prohibiting jaguar baiting (Consema Resolution 85/2011).
As the Pantanal is currently facing potential changes, especially as a result of habitat conversion (Desbiez et al., Reference Desbiez, Bodmer and Tomas2010), and human activity is the main threat to jaguars (Cavalcanti et al., Reference Cavalcanti, de Azevedo, Tomás, Boulhosa and Crawshaw2012), understanding how people perceive this species and how they coexist and interact with it and the general environment are essential to ensure the persistence of jaguars along the Paraguai River and elsewhere in the Pantanal.
