Empirical food webs of 12 tropical reservoirs in Singapore

We present 12 food webs from tropical reservoir communities in
Singapore, and summarise the topology of each with widely used network
indices (e.g., connectance, link density). Each reservoir was
surveyed over 4–6 sampling occasions, during
which, representative animal groups (i.e., fish species,
and taxonomic/functional groups of zooplankton and benthic
macroinvertebrates) and all likely sources of primary production (i.e.,
macrophytes, periphyton, phytoplankton, and riparian terrestrial plants)
were collected. We determined and measured gut content in fishes and bulk
isotope (d13C and d15N) profiles of the animals collected, which
contributed to estimating the relative strength of trophic relationships
using Bayesian mixing models. We document our protocol here, alongside a
script in the R programming language for executing data
management/analyses/visualisation procedures used in our
study. This data can be used to glean insights into
trends in inter- and intra-specific or guild interactions in analogous
freshwater lake habitats.
