Integrating scientometric analysis and zoo population data to identify knowledge and conservation gaps in three Neotropical canids
Year: 2026
Type: article
Abstract: 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.
