A pesar de los avances en registros primarios de especies, sesgos de calidad y accesibilidad en información dificultan el estudio de patrones espaciales de biodiversidad. Se presenta el primer análisis sistemático sobre los sesgos en la distribución temporal y espacial de registros de mamíferos silvestres terrestres continentales de Colombia. Mediante el uso de bases de datos, identificamos áreas administrativas y ecorregiones con los mayores vacíos de información a nivel de orden para el número de especies registradas respecto al número de especies esperadas. Además, realizamos análisis de complementariedad para establecer áreas prioritarias de muestreo que ayuden a disminuir sesgos en patrones de registro de especies de mamíferos en Colombia. La mayoría de los órdenes (70 %) presentan una representatividad menor al 50 % en al menos 40 % de los departamentos y 60 % de las ecorregiones estudiadas. Además, encontramos que la cobertura temporal en celdas de 50 * 50 km es baja, con promedio inferior a los cuatro años desde 1950 hasta 2019. El análisis de complementariedad muestra que el registro de especies a nivel nacional se maximizaría en los bosques tropicales de la Amazonía en los límites entre el departamento del Caquetá y Amazonas, el escudo Guayanés en la región de la Orinoquia, además de los ecosistemas de sabanas del Vichada, Casanare y Arauca. Proponemos la definición de esquemas depriorización y muestreo sistemático tanto para áreas aisladas y poco conocidas, como para zonas de mayor presión antrópica que pueden sufrir pérdidas locales de especies a corto plazo.

Despite recent advances in the compilation of primary biodiversity data, biases in the quality and the accessibility of the information difficult the inference of biodiversity spatial patterns. We present the first systematic analysis on the spatial distribution of terrestrial wild mammal records for continental Colombia. By using multiple databases, we identified the geopolitical areas and ecoregions from the country with the biggest information gaps at the order level regarding the number of species recorded vs the number of expected species. In addition, we carried out a complementarity analysis to establish priority sampling areas that maximize the recording of mammal species in the country. Most orders (70 %) show representativeness lower than 50 % in at least 40 % of the departments y 60 % of the studied ecoregions. Also, we found that the temporal coverage in grids of 50 * 50 km tends to below, with an average lower than four sampled years from 1950 to 2019. The complementary analysis shows several areas where sampling would maximize the record of new species at the national level. These areas include tropical forests of the Amazonian region in the limits between Caquetá and Amazonas, the Guyana region, as well as savanna ecosystems from Vichada, Casanare, and Arauca. We advocate for the definition of sampling prioritization schemes for both isolated and relatively unknown areas, as well as areas under high human pressure that could suffer from species losses in the short term.
