"On many occasions when I have used ggpairs() I’ve found myself diving into the source code to try to work out precisely what kind of plot object it produces..." -- EXACTLY my gripe.

The Forest Health and Biotic Interactions Research Unit investigates the influence of biotic and abiotic interactions on ecological processes and develops scientific principles for the protection of biodiversity. Our project Spotlight funded by the SNF (Swiss National Science Foundation), will enable a two-year position n the Forest Entomology group, starting in December 2025 or upon agreement as a PostDoc on impacts of light pollution on arthropod herbivory and behavior 80-100% (f/m/d) Artificial light at night has been identified as a primary driver of environmental change in the 21st century with key consequences for the environment. You will assess the impact of different LED lighting treatments on arthropod herbivory and herbivore predation in field experiments (forest, agricultural land). You will also conduct several lab experiments and evaluate arthropod behavioral responses to different lighting treatments. You will be part of an interdisciplinary team and your scientific findings will make an important contribution to improving sustainable outdoor lighting. You have a PhD degree in, ecology, environmental / natural sciences or in a related field. You are a dedicated scientist and motivated to conduct research on ecological processes as a function of different light pollution aspects and LED luminaire treatments. You have experience in managing and conducting field work and laboratory experiments with arthropods. You have good knowledge on ecological patterns and processes as well as basic knowledge on insect taxonomy. You are highly motivated to analyze ecological data statistically and have experience with R. You are scientifically creative and interested in interdisciplinary research with project partners from different fields. You have a good publication record in peer-reviewed scientific journals. You are well organized and work efficiently. Fluency in English (oral and writing) are required as well as a Swiss or European driver’s license (Cat B).

Improper data practices erode the quality of global ecological databases and impede the progress of ecological research The scientific community has entered an era of big data. However, with big data comes big responsibilities, and best practices for how data are contributed to databases have not kept pace with the collection, aggregation, and analysis of big data. Here, we rigorously assess the quantity of data for specific leaf area (SLA) available within the largest and most frequently used global plant trait database, the TRY Plant Trait Database, exploring how much of the data were applicable (i.e., original, representative, logical, and comparable) and traceable (i.e., published, cited, and consistent). Over three-quarters of the SLA data in TRY either lacked applicability or traceability, leaving only 22.9% of the original data usable compared with the 64.9% typically deemed usable by standard data cleaning protocols. The remaining usable data differed markedly from the original for many species, which led to altered interpretation of ecological analyses. Though the data we consider here make up only 4.5% of SLA data within TRY, similar issues of applicability and traceability likely apply to SLA data for other species as well as other commonly measured, uploaded, and downloaded plant traits. We end with suggested steps forward for global ecological databases, including suggestions for both uploaders to and curators of databases with the hope that, through addressing the issues raised here, we can increase data quality and integrity within the ecological community.
