Stochastic modeling of sediment connectivity for reconstructing sand fluxes and origins in the unmonitored Se Kong, Se San, and Sre Pok tributaries of the Mekong River

Sediment supply to rivers, subsequent fluvial transport, and the resulting connectivity on network-scales are often sparsely monitored or subject to major uncertainty. Hence, we propose to adopt stochastic modeling approaches for studying network sediment connectivity. We demonstrate such a stochastic approach for modeling sand connectivity in the major, poorly monitored Se Kong, Se San, and Sre Pok (3S) tributaries of the Mekong River. Specifically, we run many random initializations of the CASCADE modeling framework for sediment connectivity in a Monte Carlo approach in order to quantify how unknown properties of sediment sources translate into uncertainty regarding network sediment connectivity. We identify a reduced ensemble of model realizations that reproduces downstream observations of sediment transport. This ensemble presents an inverse stochastic approximation of the spatial distribution, magnitude, and variability of transport capacity, sediment flux, and bed material grain size in the entire network (i.e., upscaling point observations to the entire network). The approximated magnitude of sediment flux in each tributary is controlled by reaches of low transport capacity (“bottlenecks”). These “bottlenecks” limit the ability of the inverse stochastic approximation to predict sediment transport in the upper parts of the catchment but they allow a clear partitioning of sand deliveries from the 3S to the Mekong, with the Se Kong delivering less (1.9 Mt/yr) and coarser (median grain size: 0.4 mm) sand than the Se San (5.3 Mt/yr, 0.22 mm) and Sre Pok (11 Mt/yr, 0.19 mm).

Abdominal colour patterns of the sand diving spider Ammoxenus amphalodes (Araneae: Gnaphosidae) from South Africa

The two types of abdominal patterns found in Ammoxenus species are discussed, with emphasis on A. amphalodes Dippenaar & Meyer, 1980. With images of live specimens, the two patterns are shown. Within the genus, there is large interspecific similarity, but intraspecific variability regarding the abdominal colour pattern. Due to these variations found species are sometimes wrongly identified.

Data for "Examining functional impact and trophic morphology of small, sand-sifting fishes on coral reefs"

This data is the product of the study published as "Examining functional impact and trophic morphology of small, sand-sifting fishes on coral reefs " It contains: Feeding depth count of the two fish species used Granulometry on the experimental sediment Gut content analysis of the 8 fish used in the experiment. Measurements of maximum and minimum size of each individual prey item noted. Feeding experiment count data. ID and count data of meiobenthos (benthic meiofauna) found during the feeding experiment. The benthic community was assessed in 3 replicates for each fish individual at each timepoint. See the methods in publications for details or contact the Ole Brodnicke or Camilla Hansen for details.
