Ethnoichthyology has been highlighting in several regions of the world, due to the collaboration of studies that seek to understand the traditional or local ecological knowledge about different uses and meanings of fish among different human groups. Therefore, we present a systematic review of the literature concerning the current situation of ethnoichthyological studies in Brazil. We examine the temporal and spatial citation trends in Brazil, as well as who are the research actors and the thematic areas covered in the articles. In all, 177 published articles related to the topic were found in Brazil. The number of published articles increased significantly in time, with most studies concentrated in the Northeast Region of the country (44.4%), especially in the state of Bahia (16.8%). The types of aquatic environments include both marine and freshwater, such as sea (46.3%) and rivers (70.2%). The articles mainly rely on the collaboration of artisanal fisherman (74.3%). The topic most frequently addressed in the studies was bio-ecological aspects of fish (33.8%). On the other hand, studies on morphological aspects (2.7%) represented the less frequently among the thematic areas. We concluded that ethnoichthyology is increasing significantly in Brazil. However, some issues needed to be better understand, especially the knowledge of the recreational fishermen, the morphological aspects of the fish species by local fishermen and there are few studies in South and Midwest in Brazil, which will indicate the future efforts to improve the species conservation and the resource management.

Urban ecosystems differ from non-urban ones in the strong and rapid biocultural dynamics generated by the interactions between people from different cultures, at large spatial and temporal scales and very fast rates. This opinion piece explores the concept of urban ethnobiology as a critical field of research that investigates the complex and dynamic biocultural systems that exist in urban environments. We argue that interactions between humans and other life forms in urban ecosystems are influenced by a characteristic set of social, cultural, and political factors that are linked to urban environments, such as infrastructure development, population density, and governance structures. We emphasize the need for an interdisciplinary approach that brings together experts from different fields to study the inherent complexity of these systems. By examining the sociocultural dynamics that shape the way urban biodiversity is perceived, used, and managed, we can gain deeper insights into the different dimensions of socio-cultural biodiversity in urban areas.

Different perceptions of wildlife are usually involved in decision-making processes on the use of environmental commons and in human choices; therefore, knowing how people value nature can enhance our understanding about human-wildlife relationships. We propose to broaden the concept of cultural value by considering the trade-offs between positive and negative nature's contributions to people (NCP), including trade-offs influenced by near-past contexts. Field work was conducted with inhabitants of a rural community of the Dry Chaco of Argentina, aiming at knowing the importance of fauna in people 's lives. We conducted free listings and semi-structured interviews and calculated the cognitive salience index and five cultural value indexes (differing in the number and types of NCP categories considered). Local inhabitants were found to assess wild species by considering the satisfaction of material needs, immaterial aspects, and/or the damages that certain species may cause. The ethnospecies most widely and frequently used with material purposes in the near past and at present, and those considered the most harmful showed the highest salience values. The cultural value index that integrates both positive and negative assessments was positively correlated with cognitive salience; this relationship supports the results, showing that cognitive salience not only is conditioned by positive assessments but also captures multiple fauna assessments, including the negative ones.

Research performed in recent years indicates that efforts are still needed to understand the advances in the Caatinga, an important dry seasonal forest, and identify its potential for bioprospecting. These efforts are also important for pinpointing the challenges that should be addressed in future research focused on identifying new candidates for pharmacological studies in this complex region. Thus, in this review, we present the main advances of studies on plants and medicinal animals in the Caatinga region and their implications for ethnopharmacology, and we then discuss future challenges to promote the search for candidates with pharmacological potential. Based on an exploration of the available literature, we performed a critical reading of the available evidence to provide a good scenario on the studies in the region. We find that despite the large number of studies available, it is necessary to organize efforts to fill gaps in different areas of knowledge and optimize the search for new natural products.

Reptiles are one of the most frequently encountered animal species in the trade for traditional medicine. The use of reptiles for medicinal purposes has been documented throughout the world, impacting dozens of species. Despite the broad occurrence of reptiles in medicinal trade, there is a general lack of information concerning the scale or impact of this trade and the species involved. Here we report the sale of Common Sun Skinks Eutropis multifasciata on the island of Java in Indonesia. We surveyed 13 wildlife markets and three reptile pet stores in eight cities across Java, documenting 110 Common Sun Skinks in trade in six markets in five cities. This skink is sold for traditional medicinal purposes with several vendors stating its use to treat skin problems like "itchiness". This particular use has not been well documented in Indonesia. Further, the Common Sun Skinks were primarily sold by vendors selling Tokay Geckos for a similar purpose. This is of potential conservation concern as Tokay Geckos are harvested en masse for medicinal purposes which has resulted in significant population declines, and this could lead to potential overexploitation of the Common Sun Skink in response to this decline.

The importance of bushmeat as source of food and medicine for forest peoples calls for an appropriate benefit/risk analysis in terms of human health. In this systematic review, we compiled information on the linkages between bushmeat and health, with a particular focus on the nutritional content, the zoo-therapeutic uses and the zoonotic pool of bushmeat species in tropical and sub-tropical forest regions. Despite the scarcity of data on the nutritional content of most common bushmeat species, the available studies demonstrate that bushmeat is an important source of fats, micro and macro-nutrients and has a diversity of medicinal uses. However, bushmeat may have detrimental health impacts where hunting, transportation, handling and cooking practices do not follow food safety practices. There is evidence that some bushmeat carcasses may be contaminated by toxic metals or by polycyclic aromatic hydrocarbons. Moreover, several pathogens carried by bushmeat are found to be zoonotic and potentially transmissible to humans through consumption or through exposure to body fluids and feces. We stress the need for more in-depth studies on the complex links between bushmeat and human health. The development of innovative handling, conservation and cooking practices, adapted to each socio-cultural context, should help reduce the negative impacts of bushmeat consumption on human health.

Wild meat is a major protein supply for numerous traditional communities worldwide, but impacts ecological processes and consequently challenges the relevance and suitability of adequate monitoring of the sustainability of harvests. In this study we discuss the classic models of theoretical "maximum sustainable offtake" and propose new considerations on sustainable harvest thresholds. The study focuses on French Guiana, northern Amazonia, on four sites harvested by three communities (Amerindian, Creole, and Hmong), mainly for subsistence purposes. We explored how factors related to the number of hunters, the harvested areas, and the surface area hunted, and measured how fauna abundance generates uncertainties on models and increases the errors on sustainable thresholds. Biased or incomplete ethnologic surveys, as well as local and temporal variations in game species density could lead to considerable underestimation of harvests. We proposed a set of corrections that, once applied to the input variables of the offtake model, could limit the risk of erroneous assessment of sustainability thresholds. [ABSTRACT FROM AUTHOR]
