Diverging importance of drought stress for maize and winter wheat in Europe: Simulation Dataset10.4228/ZALF.DK.88EuropeShowOnMapView Sample DataCreative Commons BY 4.0
Webber, Heidi; Leibniz-Centre for Agricultural Landscape Research (ZALF), ORCID: http://www.orcid.org/0000000183015424
et al.
Methods:
This dataset contains output data from 9 different crop models for winter wheat and maize using projected climate data for 2040-2069 under different forcing scenarios (RCP2.6, RCP4.5 and RCP8.5). Five crop models in the dataset simulated both maize and winter wheat (4M; FASSET, FA, HERMES, HE, MONICA, MO and SIMPLACE-Lintul5, L5), while three models simulated only winter wheat (SIRIUS 2015, S2; SiriusQuality v3, SQ) and IXIM, IX simulated only grain maize. All models included a heat stress response that reduces the final yield under high temperatures, mechanisms to reduce growth and leaf area under water limitation, and account for the effects of CO2 on either RUE or photosynthesis. Five of the models include algorithms to estimate crop canopy temperature (FA, L5, HE, SS, S2). Other key details and a more extensive description of each model's treatment of heat and drought stress are listed in the supplementary materials of Webber et. al. 2018.

We analyzed bees and their food reserves after hibernation before they leave their nests. We did this for bees from three groups with different social organizations and hibernation strategies.

Dispersing species pools reveal how mobile links shape metacommunities of nectar yeasts10.4228/ZALF.DK.97QuillowShowOnMapView sample dataDownload complete datasetCreative Commons Attribution 4.0

Dispersal between local communities is a hallmark of metacommunity theory. Evidence for the effects of dispersal rates and pathways on metacommunity dynamics under field conditions is often lacking. However, studying metacommunities of yeasts in floral nectar and yeasts transported by a mobile linker community offers the opportunity to understand how species pools of passively dispersing organisms affect the community assembly. We sampled flowers and pollinators of three common tree species, identified attached yeast species and observed flower visits of different pollinator groups. We found a high overlap in yeast communities between flower and pollinator for social insects and low overlap for solitary insects. Bumblebees and honeybees transported the most nectar-specialist species, wild bees and wasps the most insect-associated yeast species, and sawflies the most transient yeast species. We found strong environmental filtering for insect-associated yeast species. Our results show that the dispersal frequency of the mobile linker community plays an important role in determining the species richness and the overall species abundance of the metacommunity, whereas local processes like environmental filtering effects mainly shape species composition. This approach offers new insights into the role of ecological filters during dispersal and colonization processes and a better understanding of resulting metacommunities.

Abstract:
The data set reveals consumers’ attitudes towards ethical issues in chicken production. The focus is on the killing practice and dual purpose chickens. It provides information on consumer purchase pattern of eggs and chicken meat, perception of animal welfare and protection issues, knowledge and perception of killing day-old chicks, attitudes towards dual purpose chickens, and socio-demographic characteristics. The raw data contains standardized responds of 1000 telephone interviews with German consumers (Berlin and Brandenburg) from 2016. A cluster analysis was performed to categorize consumers according to purchasing criteria for dual chicken products. Clusters were described by means of socio-economic variables.

Field trial data set of a six-field crop rotation for the validation of agro-ecosystem models from the Experimental Station Hohenfinow, Germany10.4228/ZALF.DK.99HohenfinowShowOnMapView sample dataDownload complete datasetCreative Commons Attribution 4.0

For the experimental site Hohenfinow (52.8115 N, 13.9266 E, altitude: 55 m), Germany, a data set of a six-field crop rotation (silage maize, winter rye, winter oilseed rape, winter barley, winter wheat, potatoes) with a field size of about 0.9 ha each is described in detail for the years 1992-1997. The Leibniz-Centre for Agricultural Landscape Research Müncheberg was responsible for carrying out the experiment and collecting all the data. The aim of the experiment was to investigate the dynamics and balances of the water and matter cycles on a deluvial site (soil type: Sandtieflehmfahlerde-Braunerde according KA5 (Albic Luvisol according WRB); site type: D3a; dry bulk density (g cm-3): 1. 48 (0-30 cm), 1.50 (30-60 cm), 1.51 (60-90 cm); field capacity (Vol%): 39.5 (0-30 cm), 39.3 (30-60 cm), 39.2 (60-90 cm); soil quality index: 36) in North-East Germany as a basis for the validation of agro-ecosystem models. Due to the location of the experimental station in the moraine landscape and the glacier history of its formation, the deposition with large stones is relatively high.

Solving the puzzle of yeast survival in ephemeral nectar systems: exponential growth is not enough10.4228/ZALF.DK.93QuillowShowOnMapView sample dataDownload complete datasetCreative Commons Attribution 4.0

​Hausmann, Sebastian Lars; Rillig, Mathias

We here examine how sufficiently high cell densities of nectar yeast can develop in a flower. In laboratory experiments, we determined the remaining fraction of nectar yeast cells after nectar removal, and used honeybees to determine the number of transmitted yeast cells from one flower to the next. The results of these experiments directly fed into a simulation model providing an insight into movement and colonization ecology of nectar yeasts.
