title: Fruit weight of coffee beans from an pollinator/vertebrate-exclosure experiment conducted in three different land use types at Mount Kilimanjaro

description: Wild animals substantially support crop production by providing ecosystem services, such as pollination and natural pest control. However, the strengths of synergies between ecosystem services and their dependencies on land-use management are largely unknown. Here, we took an experimental approach to test the impact of land-use intensification on both individual and combined pollination and pest control services in coffee production systems at Mount Kilimanjaro. We established a full-factorial pollinator and vertebrate exclosure experiment along a land-use gradient from traditional homegardens (agroforestry systems), shaded coffee plantations to sun coffee plantations (total sample size = 180 coffee bushes). The exclusion of vertebrates led to a reduction in fruit set of ca 9%. Pollinators did not affect fruit set, but significantly increased fruit weight of coffee by an average of 7.4%. We found no significant decline of these ecosystem services along the land-use gradient. Pest control and pollination service were thus complementary, contributing to coffee production by affecting the quantity and quality of a major tropical cash crop across different coffee production systems at Mount Kilimanjaro.
description: Treatment description: Poll (Pollinator): 2 randomly selected twigs of the tree where covered with gauze during coffee blossom to exclude pollinators - two randomly selected twigs were marked as control twigs, Vert (Vertebrate Exclosure): The whole coffee tree was covered with a net to exclude vertebrates (birds and bats) - two twigs were selected, Poll/Vert: combination of Poll and Vert on one tree, Control: open control with two selected twigs. On all selected twigs we counted fruitsets and harvested the fruits for quality assessment.....

title: Grid files from two AUV missions in the DISCOL area during the SONNE cruise SO242/1

description: The zip file contains grid files in UTM 16S resulted from AUV mutlibeam data processing and a table with descriptions of these grid files. AUV bathymetry data resulted from interpolation of multibeam depth measurements using the IDW algorithm in SAGA GIS. The AUV bathymetric derivatives (Bathymetric Position Index, Concavity, LS factor, and Terrain Ruggedness Index were calculated in SAGA GIS. The slope derivative was calculated in ArcMap. The AUV backscatter statistics (10th quantile, 90th quantile, mean and mode) were calculated in FMGT Geocoder. The Bayesian classification map was created in SAGA GIS using data from Bayesian classification in Matlab. The ISODATA classification map was created in SAGA GIS using the the AUV backscatter statistics and the Random Forest predictive map was created using the MGET toolbox in ArcMap and the AUV bathymetry, bathymetric derivatives and backscatter statistics data.

title: M143 raw data of EM122 multibeam echosounder (bathymetry, beam time series & water column data)

description: Multibeam echosounder (MBES) data recorded during RV METEOR cruise M143 between 12.12.2017 and 22.12.2017 in the Black Sea. The expedition aimed to investigate possible areas of seafloor depressions and slope failure along the shallow part of the Black Sea margin in the Danube Delta by bathymetry mapping and water column observation. A second emphasis is on collecting 38 kHz echosounder data in combination with multibeam water column images for quantification of gas emissions. CI Citation: Paul Wintersteller (seafloor-imaging@marum.de) as responsible party for bathymetry raw data ingest and approval. Description of data source: During the RV METEOR cruise M143 the hull-mounted Kongsberg EM122 multibeam echosounder with a nominal sounding frequency of 12 kHz was utilized. 288 beams with an acoustical footprint of 1°(Tx)/2°(Rx) are formed for each ping. For further information consult https://www.km.kongsberg.com/. During this cruise the swath angle was set to 130° and the use the of the high-density equidistant and the dual-swath mode of the EM122 resulted in up to 864 soundings per ping. The survey speed was varying between 3 and 12 knots with around 8 knots during multibeam bathymetric mapping surveys. The EM122 was recording constantly within the Romanian border with the aim to map slumping and sliding zones. The data quality was generally good, though affected by unstable weather conditions. Soft underground and shallow water depth resulted also in a strong nadir artefact, the so called 'Eric's Horn' type artefacts, which were later removed manually during the post processing phase.

title: Data on vegetation structure on the study plots of the Kilimanjaro Research Unit

description: We established eight subplots per plot. These subplots consisted of circles with a 20-m radius in densely vegetated habitats (savanna and all forest habitats) and 35.5 m × 35.5 m squares at Helichrysum plots, covering the same sampling area in all habitat types. We quantified vertical vegetation heterogeneity, canopy height and canopy closure on every subplot in the warm dry season (December to March) and in the cold dry season (July to October). To obtain vertical vegetation heterogeneity, we first estimated the vegetation cover in layers at 0, 1, 2, 4, 8, 16, 32 and 64 m above ground and then calculated the Shannon–Wiener diversity index across these eight strata. Canopy height was measured with a laser rangefinder as maximum canopy height above ground. Canopy closure was measured as the mean percentage of closed cells from four spherical canopy densitometer readings taken at the centre of each subplot in the four cardinal directions.
description: SP6 recorded several variables related to habitat structure on 8 subplots per plot. However, only 4 of these subplots (at two plots only 3) are located within the actual 50mx50m plot, while the remaining 4 subplots (at two plots 5) are located in the same habitat type and as close to the plot as possible. This dataset contains only information derived from subplots which are located within the actual plot, i.e. from 3-4 subplots per plot.Methods on:Closure of canopy area = measured with a canopy densiometer at X subplots with 4 measurements each (north, east, south, west)Vegetation heterogeneity, vertical = vegetation cover is estimated at 0, 1, 2, 4, 8, 16 and 32 m at X subplots per plot within a radius of 20 m; the Shannon-Diversity-Index is calculated over these estimates for each subplot; the minimum Shannon-Diversity-Index of all subplots is givenCanopy height = canopy height is measured with a laser range finder or estimated (if canopy height was smaller than minimum measuring distance for the LRF)

title: Data on bird communities on the study plots of the Kilimanjaro Research Unit including all bird individuals observed during point counts

description: We used audiovisual point counts on eight subplots per plot to record birds in the warm dry season (December to March) and in the cold dry season (July to October). We established circles with a 20-m radius in densely vegetated habitats (savanna and all forest habitats) and 35.5 m × 35.5 m squares at Helichrysum plots, covering the same sampling area in all habitat types. All birds heard or seen in one subplot were counted for 10 min and identified to species level. Point counts started 15 min before sunrise and were completed before 09:00. All 480 point counts (30 plots × 8 subplots × 2 seasons) were conducted by the same observer (Ferger S. W.) to reduce inter-observer variability. This dataset contains also bird individuals that were recorded higher than maximum canopy height at the respective subplots in the respective season (see publication for details).

title: Number of bite marks by animals on artificial fruits and insects after an exposure time of 96h on all focal plots of the Kilimanjaro Research Unit

description: We quantified frugivory and insectivory rates with artificial fruit and insect experiments on the focal plots of all 13 habitat types in the warm dry season (December to March) and in the cold dry season (July to October). We used non-toxic, odorless modeling clay (1) to mold spherical fruits of 14 mm diameter in three colors that have been associated with the avian seed dispersal syndrome: black, red and violet (Flörchinger et al. 2010) and (2) to mold green artificial caterpillars. We exposed the artificial fruits and caterpillars in ten clusters per focal plot with a minimum distance of 10 m between clusters. In each cluster, we placed 20 fruits per color or 20 caterpillars, respectively, resulting in a total number of 15,600 artificial fruits (13 habitat types x 10 clusters x 3 colors x 20 fruits per color and cluster x 2 seasons) and 5,200 artificial caterpillars (13 habitat types x 10 clusters x 20 caterpillars per cluster x 2 seasons). We used florist's wire to attach the fruits and caterpillars to small twigs of bushes or trees in a height of about 12 m above ground with a minimum distance of 1 m between colors and 10 cm between fruits of one color. Artificial fruits and caterpillars were exposed for 96 h hours and then checked for peck or bite marks of birds, mammals and reptiles, which indicated that a potential disperser attempted to eat the artificial fruits or caterpillars, respectively.
