CaPTrends: A database of large carnivoran population trends from around the world

Motivation Population trend information is an ‘essential biodiversity variable’ for monitoring change in over time. Here, we present a database of 1,122 population trends from around the world, describing changes abundance time large mammal species (n = 50) four families order Carnivora. For this subset taxa, provide approximately 21 times more than BioTIME and three Living Planet database. Main types variables included Key data fields each trend: species, coordinates, time-frame, methods collection analysis, series or summarized value. values are reported using quantitative metrics 75% records that collectively represent 6,500 estimates. The remaining qualitatively describe (e.g., increase). Spatial location grain Trends 621 unique locations across globe (latitude: −51.0 to 80.0; longitude: −166.0 166.0). Most (86%) found within Northern Hemisphere. Time period On average (mean), derived 6.5 observations, span 1726 2017, with 92% starting after 1950. Major taxa level measurement We conducted semi-systematic search 87 Carnivora: Canidae, Felidae, Hyaenidae Ursidae. compiled 50 species. Software format .csv.
