Reptiles used in traditional folk medicine: conservation implications

The present work provides an overview of the global use of reptiles in traditional folk medicine and the implications for conservation. The results demonstrate that at least 165 reptile species belonging to 104 genera and 30 families are used in traditional folk medicine around the world. Some species are used as sources of drugs for modern medical science. Of the reptiles recorded, 53% are included on lists of endangered species, demonstrating the importance of understanding such medicinal uses in the context of reptile conservation as well as the need for considering socio-cultural factors when establishing management plans directed towards the sustainable use of these reptiles.

Caatinga revisited: ecology and conservation of an important seasonal dry forest.

Besides its extreme climate conditions, the Caatinga (a type of tropical seasonal forest) hosts an impressive faunal and floristic biodiversity. In the last 50 years there has been a considerable increase in the number of studies in the area. Here we aimed to present a review of these studies, focusing on four main fields: vertebrate ecology, plant ecology, human ecology, and ethnobiology. Furthermore, we identify directions for future research. We hope that the present paper will help defining actions and strategies for the conservation of the biological diversity of the Caatinga.

Commercialization and use of snakes in North and Northeastern Brazil: implications for conservation and management

Snakes are sold in many markets and religious article stores in Brazil. Besides their use as food, snakes are exploited in a variety of ways, such as pets, or for use in traditional medicine and magic/religious rituals (especially in Afro-Brazilian religions). Despite widespread commercialization, there is a general lack of information about this snake trade, which makes it difficult to evaluate its magnitude and its impact on reptile populations. This work documents the commercialization and use of snakes in five cities in Northeastern (São Luís, Teresina, João Pessoa and Campina Grande) and Northern (Belém) Brazil, through interviews with 119 merchants of biological products in outdoor markets and religious articles stores. The data was gathered through the use of semi-structured questionnaires, complemented by semi-directed interviews. The products derived from 11 snake species were being commercialized for medicinal or magical/religious purposes. Boa constrictor, Crotalus durissus and Eunectes murinus were the species most commonly sold. The economic importance of snakes as sources of medicines and religious products demonstrates the need for the development of sustainable use programs for these species.

Commercialization of animal-derived remedies as complementary medicine in the semi-arid region of Northeastern Brazil

AIM OF THE STUDY In this study, we aim to document the use of animal species in traditional medicine and healing practices in the semi-arid region of Northeastern Brazil. While widespread and of great importance to large population that has limited access to contemporary medicine, such practices are poorly understood and the potential value of medicinal animal species largely unknown. MATERIALS AND METHODS Based on interviews with the merchants of medicinal animals, we calculated the informant consensus factor (ICF) to determine the consensus over which species are effective for particular ailments, as well as the species relative importance to determine the extent of potential utilization of each species. RESULTS We describe the therapeutic effects of 36 animal species used medicinally. The zootherapeutical products sold commercially are used to treat 40 health problems that were classified into 10 broad categories. We also highlight those species valued for their effectiveness against a range of ailments. The highest ICF value (0.91) was cited for diseases of the skin and subcutaneous tissue, which include relief of symptoms such as acne and furuncles. DISCUSSION AND CONCLUSION This study demonstrates that many animal species play an important role in healing practices. Animals provide the raw materials for remedies prescribed clinically and are also used in the form of amulets and charms in magic-religious rituals and ceremonies. The medicinal value of animal species depends on the local knowledge that exists within user communities, and therefore, the conservation of animal species is imperative to the preservation of local medicinal knowledge and culture.

Methods and Techniques in Ethnobiology and Ethnoecology

In this chapter the reader will have the opportunity of a brief explanation of the terms most commonly used by ethnobiologist and ethnoecologist as well as access to information about procedures for contact with the informant, theoretical and practical to check the validity and reliability of information obtained, and which the main measures to be adopted in resolving the problem of sampling.

Hunting, use and conservation of birds in Northeast Brazil

Brazil has one of the highest avifauna diversities in the world, and many species are used by human populations in many different ways. Capturing wild birds for food, or to raise as pets, or for commercial purposes, together with the loss of habitat, have been the principal causes of population reductions among many species. The present work provides new information about the diversity of wild bird species used in Ceará State (Northeast Brazil) and the techniques used for capturing them, as well as the forces motivating this hunting, the commercial relationships involved, the maintenance of captive species, and the legal and conservation implications of the use of the regional avifauna. A total of 92 wild bird species belonging to 26 families were found to be used as food (39 spp.), for medicinal (3 spp.) and magic-religious (1 spp.) purposes, for commercial ends (46 spp.), or raised as pets (44 spp.), or killed to control their predation on domestic animals (5 spp.). Raising or selling birds is motivated by their singing and/or their natural beauty, with Thraupidae, Icteridae and Emberizidae being the principal families sought after for those purposes. The Family Columbidae has the greatest importance as a food source. Eleven traditional capture techniques (both active and passive) were identified. The commercial value of the birds varied depending on both intra- and inter-specific factors, and the trade in these animals involved both dealers who sold large numbers of individuals at low prices and specialists (“passarinheiros”) who sold just a few domesticated individuals of greater value. Our evaluations of transactions taking place in public markets indicated the probable over-exploitation of a number of species, and these were often imported from other states and countries. In addition to being illegal, the capture of wild birds can cause serious environmental problems that can only be addressed through public policies directed towards education, monitoring and control, alternative sources of income, wildlife management, and ecosystem conservation.

Primates in traditional folk medicine: a world overview

Almost 50% of primates are in danger of becoming extinct, according to the criteria of the IUCN Red List of Threatened Species, one of the reasons being their consumption by humans. The reasons for hunting vary by region. One of these pretexts is the medicinal or magical value of products derived from these animals. This chapter aims at providing an overview of the global use of primates in traditional folk medicines, as well as identifying the species used as remedies associated to folk beliefs. Some important questions relating to their conservation will be addressed. Our results revealed that at least 110 species of primates, belonging to 41 genera and 11 families, are used in traditional folk practices and in magic-religious rituals throughout the world. Of the 110 species of primates recorded in our review, 22 species are classified as Vulnerable, 23 as Endangered, 14 as critically endangered, 7 as Near Threatened, 43 as Least Concern, and 1 classified as data deficient in the most recent IUCN Red List. All species are included in the CITES Appendices I or II also, although the reasons for their inclusion are not necessarily related to medicinal use. The widespread utilization of primates in traditional medicine is evidence of the importance of understanding such uses in the context of primate conservation, as well as the need for considering socio-cultural factors when establishing management plans concerning the sustainable use of these mammals.

Animal-Based Remedies as Complementary Medicines in the Semi-Arid Region of Northeastern Brazil

Animals (and their derived products) are essential ingredients in the preparation of many traditional remedies. Despite its prevalence in traditional medical practices worldwide, research on medicinal animals has often been neglected in comparison to medicinal plant research. This work documents the medicinal animals used by a rural community in the semi-arid region, inserted in Caatinga Biome, where 66 respondents provided information on animal species used as medicine, body parts used to prepare the remedies and illnesses to which the remedies were prescribed. We calculated the informant consensus factor to determine the consensus over which species are effective for particular ailments, as well as the species use value to determine the extent of utilization of each species. We recorded the use of 51 animal species as medicines, whose products were recommended for the treatment of 68 illnesses. The informant consensus in the use of many specific remedies is fairly high, giving an additional validity to this folk medicine. Eight species not previously reported as having medicinal use were recorded. The local medicinal fauna is largely based on wild animals, including some endangered species. Given a high proportion of medicinal animals observed in the study area, it is logical to conclude that any conservation strategy should include access to modern health care.

Ethnozoology in Brazil: current status and perspectives

Ancient connections between animals and human are seen in cultures throughout the world in multiple forms of interaction with the local fauna that form the core of Ethnozoology. Historically, ethnozoological publications grew out of studies undertaken in academic areas such as zoology, human ecology, sociology and anthropology - reflecting the interdisciplinary character of this discipline. The rich fauna and cultural diversity found in Brazil, with many different species of animals being used for an extremely wide diversity of purposes by Amerindian societies (as well as the descendents of the original European colonists and African slaves), presents an excellent backdrop for examining the relationships that exist between humans and other animals. This work presents a historical view of ethnozoological research in Brazil and examines its evolution, tendencies, and future perspectives. In summary, literature researches indicated that ethnozoology experienced significant advances in recent years in Brazil, although from a qualitative point of view improvement is still needed in terms of methodological procedures, taxonomic precision, and the use of quantitative techniques. A wide range of methodologies and theories are available in different areas of learning that can be put to good use in ethnozoological approaches if the right questions are asked. The challenges to studying ethnozoology in Brazil are not insignificant, and the tendencies described in the present study may aid in defining research strategies that will maintain the quantitative growth observed in the recent years but likewise foster needed qualitative improvements.

The medicinal animal markets in the metropolitan region of Natal City, northeastern Brazil

AIM OF THE STUDY This study investigates the trade of animals for medicinal purposes in Natal metropolitan area, northeastern Brazil, to document which animal species are used, how and for what purposes. This study also discusses the implications of the use of zootherapeutics for wildlife conservation. MATERIALS AND METHODS Based on interviews with merchants of medicinal animals in all open fairs of the metropolitan region of Natal City, we calculated the informant consensus factor (ICF) to determine the consensus over which species are effective for particular ailments, as well as the species relative importance to determine the extent of potential utilization of each species. RESULTS We describe the therapeutic effects of 23 animal species used medicinally. The zootherapeutical products sold commercially are used to treat 34 health problems that were classified into 14 broad categories. We also highlight those species valued for their effectiveness against a range of ailments. The highest ICF value (1.0) was cited for diseases of the circulatory system, which include relief of symptoms such as stroke, hemorrhage, varicose veins and edema. DISCUSSION AND CONCLUSION Our study indicated that the local population holds a great deal of ethnomedical knowledge about their local animal resources, and highlights the need for clinical investigations of these traditional remedies to test the safety and efficacy. The animal species identified in this study not only hold high medicinal value for local populations, but could potentially be a source of healing compounds that could aid pharmaceutical research. While the impact of these practices on animal populations is unknown, the high extractive value of these animal populations and the associated medicinal traditional knowledge, needs to be considered in any conservation strategy aimed at the faunistic resources of this area.
