Ecosystem services delivered by Brazilian mammals: spatial and taxonomic patterns and comprehensive list of species

Le résumé fourni par la source

For the 701 mammals that occur in Brazil (ca. 13% of extant mammals worldwide), we attributed ES to each deliverer one based on their functional traits, known trophic interactions, expert knowledge, and by overlaying IUCN's distribution maps of the species. The ES term encompasses both ecosystem processes and services, offering a broader perspective that enables us to investigate the potential benefits of mammals to people. We assumed that species that are currently listed as threatened in the IUCN most likely lost their ES role. We found that 82% of Brazilian mammals (575 spp.) deliver at least one of the 11 ES identified. Cultural services were associated with the greatest number of deliverer species, while carrion control, ecosystem engineering, and rodent control were delivered by fewer species. Although only 24% of the species analyzed here are endemic to Brazil, 75% of them deliver at least one ES. The ES they delivered are also disproportionately at risk, as 57% of the species considered to have lost their ES role are endemic. Ecosystem service provision does not merely mirror the spatial patterns of mammal richness in general, as we identified hotspots for each service across Brazil, including its seascapes. Our comprehensive assessment provides a clear overview of the myriad of services delivered by Brazilian mammals, including taxonomic and spatial explicit information for each service. Identifying and mapping species and their services can contribute to more effective management and conservation programs focused on optimizing the supply of ES and conserving biodiversity.
