(Uploaded by Plazi for the Bat Literature Project) The last 50 years have witnessed rapid changes in the ways that natural history specimens are collected, preserved, analyzed, and documented. Those changes have produced unprecedented access to specimens, images, and data as well as impressive research results in organismal biology. The stage is now set for a new generation of collecting, preserving, analyzing, and integrating biological samples—a generation devoted to interdisciplinary research into complex biological interactions and processes. Next-generation collections may be essential for breakthrough research on the spread of infectious diseases, feeding Earth's growing population, adapting to climate change, and other grand research challenges. A decade-long investment in research collection infrastructure will be needed.
