摘要

This study provides an overview of the scientific literature and zoo distribution data for three threatened canid species in Brazil: the short-eared dog (Atelocynus microtis), the hoary fox (Lycalopex vetulus), and the bush dog (Speothos venaticus), for which the extent of knowledge on biology, ecology, and ex-situ management remains unclear, highlighting the need for systematic evaluation. A scientometric analysis of articles published between 1975 and 2023 was combined with an assessment of Zoological Information Management System (ZIMS) data on ex-situ populations. A total of 433 articles were identified, of which 168 were selected. Because some studies included more than one species, species-specific counts were not mutually exclusive and comprised 16 articles on the short-eared dog (Atelocynus microtis), 47 on the hoary fox (Lycalopex vetulus), and 105 on the bush dog (Speothos venaticus). Scientific production began in 1981 and increased steadily over time, with the bush dog being the most studied species and the short-eared dog the least. The short-eared dog was not represented in the ZIMS database. Most studies were conducted in-situ (116; 61.38%), followed by ex-situ (60; 31.74%), with only two combining both approaches (1.06%). Research spanned 13 areas, with parasitology (31; 18.45%) and conservation (28; 16.67%) being the most represented. Despite advances, including reproductive and behavioural studies in captivity, knowledge remains uneven across aspects of biology, ecology, and behaviour, particularly in integrating ex-situ and in-situ information. These limitations may hinder the refinement of management and conservation strategies. This study highlights the need for targeted research that combines field-based studies and strategically designed ex-situ investigations to strengthen conservation planning.
