Many resources assemble species-level trait data, but the data and metadata underlying those trait measurements are often not reported. Here, we introduce FuTRES (Functional Trait Resource for Environmental Studies; pronounced few-tress), an online datastore and community resource for individual-level trait reporting that utilizes a semantic framework. FuTRES already stores millions of trait measurements for paleobiological, zooarchaeological, and modern specimens, with a current focus on mammals. We compare dynamically derived extant mammal species' body size measurements in FuTRES with summary values from other compilations, highlighting potential issues with iScienceA solution to the challenges of interdisciplinary aggregation and use of specimen-level trait data.PMC9535407175980817598981759821Walls RLGuralnick RPDavalos LMKohli BKing JNCruz JABalk MAHopkins SLaFrance RSewnath NBoileau AEmery KFBrenskelle LBarrett PVillasenor AMorgan MEDavis EBMcCrane SMReuter DBlois JMcLean BHantak MMKoo MSUpham NSYohe LDeck JPilaar Birch SReitz EJMachado HCannarozzi NRGyawali PReed Dde la Sancha NULawing AMArroyo-Cabrales JfalseA solution to the challenges of interdisciplinary aggregation and use of specimen-level trait data.Understanding variation of traits within and among species through time and across space is central to many questions in biology.
