Title Animal tissue carbon and nitrogen content
Downloaded 2 times
Description Carbon and nitrogen content as % of dry mass for 391 macro-invertebrate individuals (four feeding types: detritivore, herbivore, omnivore, predator) sampled on the core sites of the EFForTS project (http://www.uni-goettingen.de/en/310995.html) in the Jambi Province on Sumatra, Indonesia in 2012. Sites are coded as landscape-transformation system-replicate (two landscapes: Bukit Duabelas and Harapan; four transformation systems: Forest, Jungle rubber, Rubber, Oil palm). Sample.code is an object identifier.

Title Leaf-litter tissue carbon and nitrogen content
Downloaded 3 times
Description Carbon and nitrogen content as % of dry mass for 169 leaf-litter specimen sampled on the core sites of the EFForTS project (http://www.uni-goettingen.de/en/310995.html) in the Jambi Province on Sumatra, Indonesia in 2012. Sites are coded as landscape-transformation system-replicate (two landscapes: Bukit Duabelas and Harapan; four transformation systems: Forest, Jungle rubber, Rubber, Oil palm). Leaf.sample.code is an object identifier. Rubber.leaf and oilpalm.leaf identify specimens as being rubber or oil palm leaves (1) or not (0).

Title Macro-invertebrate community data per site and feeding type
Downloaded 2 times
Description Animal community data for litter macro-invertebrates of four different feeding types (detritivore, herbivore, omnivore, predator) sampled on the core sites of the EFForTS project (http://www.uni-goettingen.de/en/310995.html) in the Jambi Province on Sumatra, Indonesia in 2012. Sites are coded as landscape-transformation system-replicate (two landscapes: Bukit Duabelas and Harapan; four transformation systems: Forest, Jungle rubber, Rubber, Oil palm). Dens gives the density as number of individuals m-2, div is the number of morphospecies per core site, bmass is the fresh biomass in mg m-2 and metabolic.demand is the sum of the individual metabolic rates of all individuals found per area in W m-2. For further details on the animal sampling and calculation of metabolic rates see Barnes & Jochum et al., NatCommun, 2014 (doi:10.1038/ncomms6351).

Title Data for main analyses and Figure 3
Downloaded 1 time
Description Processed data on leaf litter, detritivore (Det) and predator (Pre) communities sampled on the core sites of the EFForTS project (http://www.uni-goettingen.de/en/310995.html) in the Jambi Province on Sumatra, Indonesia in 2012, used to perform the main analyses and plot Figure 3. Sites are coded as landscape-transformation system-replicate (two landscapes: Bukit Duabelas and Harapan; four transformation systems: Forest, Jungle rubber, Rubber, Oil palm). CN is the unitless ratio of dry-mass carbon to dry-mass nitrogen for leaf litter (single measurements weighted after relative importance of specimens in the local leaf litter) and animal tissue (averaged over measured individuals) per core site. Litter.mass gives the dry litter mass per ground area in g cm-2. Dens gives the density as number of individuals m-2, div is the number of morphospecies per core site, biomass is the fresh biomass in mg m-2 and per-unit-biomass consumer feeding rates were calculated as W mg-1. Note that data are non-logged and non-normalized.
