Description
The biological inventory assemblages, along with summary statistics such as their area, richness and trait values [mean(variance)]. All inventories were originally based on Meese (2005). For both birds and mammals we use five similar trait categories: diet, body size, activity time and two measures of foraging niche. Assemblage mean mass is based on log transformed data. Diet include estimates of the proportional use of each of seven dietary categories for mammals (seeds, fleshy fruits, nectar and pollen, other plant material, invertebrates, fish, vertebrates) and eight dietary categories for birds (seeds, fleshy fruits, nectar and pollen, other plant material, invertebrates, fish, carrion, other vertebrates. For birds the first foraging niche trait reflects proportional use of each of seven foraging categories (in water below surface of water, in water on surface, terrestrial ground-level, understory, mid-canopy, upper canopy, aerial). The second foraging niche trait separates species according to their broad habitat affinity to freshwater or terrestrial. Values for diet and, for birds, the first foraging trait are based on proportional use x 10. For mammals, the first foraging niche trait include foraging height categories on an ordinal scale (1 – fully arboreal, 2- scansorial, 3 - terrestrial). The second mammalins forgaing niche trait is the degree to which a species is fossorial on an ordinal scale (1 – not fossorial, 2- semi fossorial, 3 - fully fossorial). ). Activity time included five ordinal variables (1 - nocturnal, 2- nocturnal and crepuscular, 3- crepuscular or cathemeral, 4- diurnal and crepuscular, 5- diurnal). Note that not all assemblages were used for both taxa.
