Title Dung beetle preference
Downloaded 59 times
Description The first excel sheet ("Callibration beetle_weight") contains a table with numbers of dung beetles and their corresponding weights. The second excel sheet ("Dung beetle preference study") contains a table describing the number of dung beetles caught after 12, 24 or 36 hours with dung of different herbivore species. In the third excel sheet ("Dung watercontent") we calculated the water content of dung from different herbivore species: "el" is elephant, "wl" is wildebeest, "zb" is zebra and "bf" is buffalo.

Title Dung decomposition experiment
Downloaded 52 times
Description The first excel sheet ("all data") is an overview of the dung decomposition experiment containing the relative weight and nutrient (C, N and P) loss together with C, N and P release rates of dung from different herbviore species ("bf" is buffalo, "gf" is giraffe, "rb" is reedbuck, "wb" is waterbuck, "wh" is warthog and "wl" is wildebeest) collected after 41 or 167 days. Dung was placed in dung bags with a fine (mesh.size =1) or coarse (mesh.size = 2) mesh, whereby the latter allowed acces of macrofauna to the dung. Signs of termite and/or dung beetle attack were recorded in the "termites" and "dungbeetles" columns, which were combined to form the "soil.fauna" column. The second excel sheet ("t=0") contains a table with weight and nutrient contents of the dung at the start of the experiment.

Title Dung beetle experiment
Downloaded 48 times
Description First excel sheet ("dungbeetle cages") is an overview table of relative biomass loss and C, N and P release rates from dung undergoing different dung beetle and crushing treatments: "nodb.nomash" is no dung beeltes + not crushed, "nodb.mash" is no dung beetles + crushed, "db.nomash" is dung beetles + not crushed and "db.mash" is dung beetles + crushed. Weight and nutrients of the dung at the start of the experiment are indicated by "t0" and these are calculated from data in the second excel sheet ("t0_all species"). Weight and nutrients of the dung when collected (either at day 15, 29 or 47) are indicated by "tx".

Title Dung deposition per collection time
Downloaded 43 times
Description This excel file consists of several sheets representing different dung collection times (time0-time13). The sheets describe at which site (MAC = Mkwaja area and SAC = Saadani area) dung was collected (in biomass) and which herbivore species deposited that dung. Time0, time6 and time10 were collection times at the start of a field season in which the dungplot was cleared; these data were not taken into account for the dung deposition analyses.

Title Dung deposition per guild
Downloaded 52 times
Description In this excel file the dung deposition data of "Dung deposition per collection time.xls" are combined into dung biomass deposited per herbivore feeding strategy and digestive physiology group (noted as column "guild" in the file): "rum.br" is ruminant browser, "nonrum.gr" is non-ruminant grazer and "rum.gr" is ruminant grazer. The dung biomass deposition is combined with the N and P contents of dung in dry and wet periods to estimate annual N and P inputs through dung.

Title Dung nutrient overview
Downloaded 63 times
Description An overview of dung nutrient concentrations (C, N and P) and ratios of the most common herbivore species of Saadani National Park collected on several occasions during two years. Dung was collected for several experiments (under column "data": see excel file for abbreviations of experiments) and in two areas (under column "location": "SA" is Saadani area, "MK" is Mkwaja area).
