Abstract

Snares are one of the most used types of non-selective traps for hunting worldwide, though their use is prohibited in many countries, including Brazil. Indiscriminate and unmonitored use of snares can induce serious conservation problems, particularly in megadiverse countries where higher species richness and diversity mean that the probability of injuries and deaths to non-target species increases. In Brazil, there is evidence of injuries and deaths of species of conservation concern after being trapped in snares set to capture feral pigs. Here, we used data from the general media, YouTube (TM) and an animal rehabilitation centre database to: (1) provide an overview of the use of snares in Brazil; (2) identify the target species of snares and the Brazilian medium- and large-sized mammals most frequently registered as captured by this type of trap; and (3) describe the detected impacts on trapped animals. We found that the use of snares in Brazil is underreported, widespread and has harmful consequences for medium and large-sized mammals. Furthermore, we show how social media is a catalyst for the dissemination of tutorials on how to manufacture and use snares. We discuss our results in terms of: (1) lessons for the reduction of the impact of snares on non-target species, awareness-raising of specific stakeholders and rights-holders of the impacts of indiscriminate use of snares and of alternatives to their use, and the effective implementation and monitoring of existing regulation of feral pig hunting and population control in Brazil; and (2) how social media contributes to the propagation of illegal hunting practices and how it can be used as a tool to study the prevalence and impacts of such practices.Read the free for this article on the Journal blog. La & ccedil;os s & atilde;o um dos tipos mais usados de armadilhas n & atilde;o seletivas para ca & ccedil;a em todo o mundo, embora seu uso seja proibido em muitos pa & iacute;ses, incluindo o Brasil. O uso indiscriminado e sem monitoramento de la & ccedil;os pode causar s & eacute;rios problemas de conserva & ccedil;& atilde;o, especialmente em pa & iacute;ses megadiversos, onde a maior variedade de esp & eacute;cies aumenta a probabilidade de ferimentos e mortes de animais que n & atilde;o eram o alvo da armadilha. No Brasil, h & aacute; evid & ecirc;ncias de ferimentos e mortes de esp & eacute;cies de interesse para conserva & ccedil;& atilde;o ap & oacute;s serem presas em la & ccedil;os armados para capturar javalis. Neste estudo, utilizamos dados da m & iacute;dia em geral, do YouTube (TM) e de um banco de dados de um centro de reabilita & ccedil;& atilde;o de animais para: (1) fornecer uma vis & atilde;o geral do uso de la & ccedil;os no Brasil; (2) identificar as esp & eacute;cies-alvo dos la & ccedil;os e os mam & iacute;feros de m & eacute;dio e grande porte mais frequentemente registrados como capturados por esse tipo de armadilha; e (3) descrever os impactos detectados nos animais capturados. Constatamos que o uso de la & ccedil;os no Brasil & eacute; subnotificado, amplamente disseminado e traz consequ & ecirc;ncias prejudiciais para mam & iacute;feros de m & eacute;dio e grande porte. Al & eacute;m disso, mostramos como as redes sociais funcionam como catalisadoras na dissemina & ccedil;& atilde;o de tutoriais sobre como fabricar e usar la & ccedil;os. Discutimos nossos resultados em termos de: (1) li & ccedil;& otilde;es para reduzir o impacto dos la & ccedil;os sobre esp & eacute;cies n & atilde;o-alvo, aumentar a conscientiza & ccedil;& atilde;o de grupos espec & iacute;ficos sobre os impactos do uso indiscriminado de la & ccedil;os e sobre alternativas ao seu uso, al & eacute;m da implementa & ccedil;& atilde;o efetiva e do monitoramento da regulamenta & ccedil;& atilde;o existente para a ca & ccedil;a e o controle populacional de javalis no Brasil; e (2) como as redes sociais contribuem para a propaga & ccedil;& atilde;o de pr & aacute;ticas ilegais de ca & ccedil;a e como podem ser usadas como ferramenta para estudar a preval & ecirc;ncia e os impactos dessas pr & aacute;ticas.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2026-04-04:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 8.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 6 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 1.
  • The number of mentions on the social network X (formerly Twitter): 1 (Altmetric).

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

  • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
