Like Pavel @kratina.bsky.social, I greatly enjoyed the friendly atmosphere at the GRC conference on predator-prey interactions. Main highlights: lots of inspiring talks and posters, meeting new colleagues and old friends, and night-spotting endemic salamanders. Hoping to come back in two years!

It was great to catch up with some old friends and colleagues at the Gordon Research Conference on predator-prey interactions in Italy last week, including a night chase of salamanders and a brief stroll through Florence. @davidboukal.bsky.social

#SEBconference is underway! Many talks focus on the effects of #climate #warming and other stressors on aquatic animals. My colleague Claire Duchet presented our #mesocosm study linking individual responses to warming and #pharmaceuticals to changes in communities and ecosystem services.

Fresh blood for freshwaters goes virtual in 2025! Great networking and learning opportunity for ECRs working on all freshwater related things.💧

A critical read for anyone who has used or is thinking of using
#TRY plant trait data -- "Currently, ecological analyses using TRY data appear, at best, not as powerful as they can be and, at worst, wrong." -- We likely need to start anew and rebuild how we share, access, and cite #PlantTrait data

1/ Important read for anyone using, contributing, or building large databases by aggregating data sources. Discusses issues with data quality, duplication, credit attribution, etc, and includes recommendations for improvement

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.
