Study Locations
Our final set of 28 studies were located across the tropics (n = 22) and sub-tropics (n = 6), although studies from South America (n=10) and Australasia (n = 7) dominated (Fig 1). Five studies were in the Tropical and Subtropical Moist Broadleaf Forests (TSMBF), six in the TSDBF (Tropical and Subtropical Dry Broadleaf Forests), one in TSCF (Tropical and Subtropical Coniferous Forests), 13 in the TSGSS (Tropical and Subtropical Grasslands, Shrublands and Savannas), and three in the FGS (Flooded Grasslands and Savannas) biomes (Fig 1).
