BUSCADOR RECOLECTA

Monitoring of an experimental plantation of Mediterranean woody species during four years after planting. Information includes plant location, experimental plot, density, species mixture, annual survival, annual growth, and categories of plant vigor. Plant growth is derived from linear measurements: height, crown diameter, and basal diameter., The dataset was used for analyzing the effect of plant density and species composition in the neighborhood on survival and relative growth rates of planted focal individuals, Data collection was funded by the Andalusian Department of Environment and the Andalusian Department of Innovation, Science and Enterprise (P06-RNM-01903) and the European Regional Development Fund. Data processing was funded by the Spanish National Research Agency (AEI; CGL2016-75205-R) and the European Regional Development Fund., Peer reviewed

© 2021 by the authors., Detecting rapid changes in mammal composition at large spatial scales requires efficient detection methods. Many studies estimate species composition with a single survey method without asking whether that particular method optimises detection for all occurring species and yields reliable community-level indices. We explore the implications of between-method differences in efficiency, consistency, and sampling effort for the basic characterisation of assemblages of medium to large mammals in a region with three contrasted Mediterranean landscapes. We assessed differences between camera traps, scent stations, scat surveys, and track surveys. Using track surveys, we detected all species present in the regional pool (13) and obtained the most accurate description of local species richness and composition with the lowest sampling effort (16 sampling units and 2 survey sessions at most). Had we chosen camera traps, scent stations, or scat surveys as the only survey method, we would have underestimated species richness (9, 11, and 12 species, respectively) and misrepresented species composition in varying degrees. Preliminary studies of method performance inform whether single or multiple survey methods are needed and eventually which single method might be most appropriate. Without such a formal assessment current practices may produce unreliable and incomplete species inventories, ultimately leading to incorrect conclusions about the impact of human activity on mammal communities., This research was funded by the Spanish National Research Agency (AEI; grant CGL2016-

Monitoring of 13 species at six-month intervals during two years in order to describe spatial variation in the composition of the mammal assemblage. The dataset includes species occurrence in 400-ha sampling plots, measurements of vegetation cover at the microhabitat scale, proxies of human disturbance, and aggregate indices of land use composition in the landscape within and around sampling plots., Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)., The dataset was used for analyzing the relative effect of spatial, environmental, and biotic factors on community assembly, Field data:
