Total energy expenditure (TEE) of zoo-housed Matschie’s tree kangaroos (Dendrolagus matschiei).

Phylogram of marsupial species used in the comparative TEE dataset.
The phylogenetic structure was pruned from the TimeTree supertree (Kumar et al., 2017). Solid circles indicate nodes that map directly to the National Center for Biotechnology Information (NCBI) Taxonomy and the open circles indicate nodes that were created during the polytomy resolution process.
Fig 2.
Comparison of TEE (kcal day-1) versus body mass (kg) for marsupials (A: n = 32 species organized by nine families) and Macropodidae (B: n = 9 species organized by six genera). Shaded regions indicate 95% confidence intervals for the linear regressions. Arrows indicate Matschie’s tree kangaroo (Dendrolagus matschiei) mean TEE value from this study. Published TEE values for 31 marsupial taxa taken from Hume [11], Munn et al. [26–28], and Sale et al. [29].

Macronutrient intake, fecal output, and apparent digestibility in zoo-housed Matschie’s tree kangaroos (Dendrolagus matschiei).
Fig 3.
Daily ME intake (kcal day-1) and body mass (kg; secondary y-axis) by month for the female (A) and male (B) Matschie’s tree kangaroo (Dendrolagus matschiei). Solid horizontal line indicates TEE (kcal day-1) in the month it was quantified. Dotted horizontal line represents the mean ME intake over the course of the 14-month study. Black dots represent mean body mass value per month.
Fig 4.
Daily ME intake (kcal day-1) attributed to browse and non-browse food items consumed by the female and male Matschie’s tree kangaroo, respectively, over the course of the 14-month study.
Error bars indicate the standard error of mean values.
