Data from: Homogenisation of carnivorous mammal ensembles caused by global range reductions of large-bodied hypercarnivores during the late Quaternary
Carnivorous mammals play crucial roles in ecosystems by influencing prey densities and behaviour, and recycling carrion. Yet, the influence of carnivores on global ecosystems has been affected by extinctions and range contractions throughout the Late Pleistocene and Holocene (~130 000 years ago to the current). Large-bodied mammals were particularly affected, but how dietary strategies influenced species' susceptibility to geographic range reductions remains unknown. We investigated 1) the importance of dietary strategies in explaining range reductions of carnivorous mammals (≥5% vertebrate meat consumption), and 2) differences in functional diversity of continental carnivore ensembles by comparing current, known ranges to current, expected ranges under a present-natural counterfactual scenario. The present-natural counterfactual estimates current mammal ranges had modern humans not expanded out of Africa during the Late Pleistocene and were not a main driver of extinctions and range contractions, alongside changing climates. Ranges of large-bodied hypercarnivorous mammals are currently smaller than expected, compared to smaller-bodied carnivorous mammals that consume less vertebrate meat. This resulted in consistent differences in continental functional diversity, whereby current ensembles of carnivorous mammals have undergone homogenisation through structural shifts towards smaller-bodied insectivorous and herbivorous species. The magnitude of ensemble structural shift varied among continents, with Australia experiencing the greatest difference. Weighting functional diversity by species' geographic range sizes caused a three-fold greater shift in ensemble centroids than when using presence-absence alone. Conservation efforts should acknowledge current reductions in the potential geographic ranges of large-bodied hypercarnivores and aim to restore functional roles in carnivore ensembles, where possible, across continents.

A large ensemble of spatially and annually averaged CESM CAM 100-year data
This repository contains data from an ensemble of 100-year runs on the Cheyenne computer at NCAR. The purpose of this data set is to allow an investigation of how different variables are affected by software and hardware modifications at different time scales. The data was produced by a CESM 1.3 series tag using the CAM5 model version described in Kay et al. (2015). The simulations are CESM startup runs using a present-day F compset (active atmosphere and land, data ocean, and prescribed ice concentration), CAM5 physics at approximately 1 degree latitude/longitude resolution, and the spectral element dynamical core. The output contains CAM data from 147 simulations each with a 100-year time series (100 time points) of 134 variables. Of the 147 runs, 139 are control runs that differ only by an order double precision perturbation to the initial temperature, where 114 were from an Intel compilation and 25 from a GNU compilation. The remaining 8 runs are so-called test runs, each with a single modification (e.g., single parameter, compiler, minor code change) changed relative to the control runs. The simulations originally output monthly data. The modestly sized dataset released here is a result of annually averaging the monthly files, and then spatially averaging the annual averages over the grid. Each of the 147 NetCDF files corresponding to a single simulation contains the variable names and a matrix of 100 years of annual averages for each variable.
