This article compares the local ecological knowledge (LEK) of quilombolas in the Atlantic Forest (Brazil) to scientific knowledge about the diet of four ungulate taxa (Tapirus terrestris L., Mazama spp., Pecari tajacu L., Tayassu pecari Link). LEK was gathered through interviews conducted with the freelisting method and through closed questionnaires. Ecological studies were compiled via a systematic review of the specialized academic literature. The research detected points of convergence and divergence between these knowledge systems. Local knowledge of the food classes in the ungulate diet indicated a wider range of items than that observed in 65 scientific studies of the foraging habits of these species. Certain characteristics of the LEK, such as its principal focus on environments that are not commonly investigated by ecological studies, form the basis of these divergences and reveal the complementary potential of LEK relative to scientific data in this field.

Indigenous Reserves have played an indispensable role in maintaining forest areas in the Neotropics. In the Amazon there is a clear correlation between these reserves and the presence of forest cover; however, the simple presence of uninterrupted vegetation is no guarantee for the conservation of biodiversity, especially where hunting is practiced. This study describes hunting practices among the Awá-Guajá people from 1993 through 1994, also identifying sociocultural, technological, and demographic changes that have influenced their resource acquisition strategies over the last two decades. The data was obtained through ethnographic fieldwork, recording 78 days of foraging returns, with follow-up visits through 2010. This work provides useful information for an effective diachronic analysis of hunting in this community, by revealing foraging patterns of the early to mid-1990s, and describing community transformations over the last two decades in this locale.

BackgroundLocal ecological knowledge (LEK) has been discussed in terms of its similarities to and its potential to complement normative scientific knowledge. In this study, we compared the knowledge of a Brazilian quilombola population regarding the habitat use and life habits of large mammals with in situ recordings of the species. We also tested the hypothesis that quilombola LEK has a special focus on the anthropogenic portion of the landscape.MethodsThe habitats investigated were anthropogenic secondary forests and mature forests in the southeastern Atlantic coast of Brazil. We conducted the faunal survey using the camera-trap method. The sampling effort consisted of deploying 1,217 cameras/day in the mature forests and 1,189 cameras/day in the secondary forests. Statistical comparisons regarding the habitat use of the species were based on the randomization procedure. We interviewed 36 men who were more than 40 years old in the three communities studied. Informal, semi-structured and structured interviews were used. Two variables were considered in the LEK analyses: level of internal agreement and level of convergence with the scientific data.ResultsThe camera trap sampling resulted in a total of 981 records. Animals such as opossums, tayras, armadillos and deer showed a non-selective pattern in the use of habitats. In contrast, the coati was more common in mature forests. We found that nearly 40% of the interviewees’ responses converged with the scientific data on the use of habitats. However, the LEK on the species’ life habits was highly convergent with the scientific data. The hypothesis that secondary forests would have a greater relevance for local knowledge was validated for four of the five analyzed species.ConclusionsWe suggest two principal considerations of ecological and ethnoecological interest: (1) In the Atlantic Forest of the Ribeira Valley, the secondary forests resulting from shifting cultivation were as attractive to the species as the mature forests; (2) The LEK has a special focus on the more anthropogenic portion of the landscape studied. Finally, we argue that this environmental focus in LEK is part of what makes it different from scientific knowledge and unique in its approach toward local environments.

In this article, we investigate the loss of local ecological knowledge (LEK) of wild mammals among quilombolas in southeastern Brazil. Using an Event Ecology approach, free listing exercises, questionnaires, and semi-structured interviews, we recorded local knowledge relevant to wild mammals as well as key events in the life histories of residents. Next, we built a causal model connecting age; formal education; years outside the community; years in the pre-village context; and individuals’ degree of LEK. Statistical analysis showed that the formation of sedentary communities and the abandonment of swidden cultivation among young people are the main sources of the erosion of LEK observed. This is the first study connecting a decrease in swidden cultivation with loss of local knowledge about fauna. The importance of swidden cultivation for non-agricultural domains of knowledge was somewhat surprising and particularly relevant in the current scenario of a worldwide collapse of this horticultural system.

The wildlife of the Brazilian Cerrado is threatened by large-scale habitat loss, in particular due to conversion to agricultural land. It is essential to study how the mammal fauna copes with the highly fragmented, human-influenced, non-protected landscape. The paper presents the results of a survey of the large to mediumsized mammals of a typical cattle ranch with a mixture of human-created and natural vegetation types. We recorded 18 species. Surprisingly, several species were found to still thrive in the area, however, many species are rare or have become extinct. We conclude the paper with comments relevant for the conservation of mammals in the Cerrado as a whole.

In addition to shedding light on underlying ecological processes, studies about animal diets are useful for guiding the design of species conservation projects. This study presents general characterizations of the diets of five neotropical ungulates, the lowland tapir (Tapirus terrestris), the red brocket deer (Mazama americana), the grey brocket deer (Mazama gouazoubira), the collared peccary (Pecari tajacu) and the white-lipped peccary (Tayassu pecari). In addition, a critical review of methodological procedures used in this field of ecology is presented. A number of methodological limitations were identified in this review, which may help guide future research in this field. The predominant types of studies reviewed focused on analyses of fecal matter and stomach contents. Direct observation of foraging, while difficult to implement, has revealed interactions among ungulates and other mammals that are otherwise difficult to observe. The general foraging patterns of various species and the main ecological roles of the species in the various environments where they occur were also observed. A list of plant species and families is also presented here to aid researchers and conservation practitioners in accessing resources about the main items in the ungulate diets discussed in this study.

RESUMOAlém de revelar processos ecológicos subjacentes, estudos sobre a dieta de espécies da fauna também geram informações úteis para o delineamento de projetos visando a conservação das mesmas. Esta revisão apresenta uma caracterização geral da dieta de cinco ungulados neotropicais, a anta (Tapirus terrestris), o veado mateiro (Mazama americana), o veado catingueiro (Mazama gouazoubira), o cateto (Pecari tajacu), e o queixada (Tayassu pecari), juntamente com uma avaliação crítica dos procedimentos metodológicos que têm sido adotados nesse campo do conhecimento ecológico. Algumas limitações metodológicas foram identificadas, o que pode servir de base de reflexão para pesquisas futuras nessa área. As análises do conteúdo fecal e estomacal predominaram entre os estudos. Já o método de observação direta do forrageio, apesar da sua difícil aplicação, foi ímpar ao revelar interações entre ungulados e outros mamíferos ainda pouco conhecidas da Ciência. Padrões gerais no forrageio das espécies também foram evidenciados, assim como os principais papéis ecológicos que as mesmas podem desempenhar nos diferentes contextos ambientais em que ocorrem. Uma lista de espécies e famílias botânicas também é apresentada, e visa facilitar o acesso de pesquisadores e de ambientalistas aos recursos que até o momento são tidos como os principais itens da dieta desses animais.
