Replication studies: a win-win for early-career training and behavioral ecology Replicating previous research builds confidence that results are real and meaningful. But close replications are rare due to limitations in resources and d

How do we know our research results are REAL? We replicate them! Most folks agree but lament on how hard it is to publish these replications.

My dearest gentle reader, lament no more! Delighted to unveil: Replication Studies, a new section of Behavioral Ecology 1/

A recent paper claims, opposed to what conservation science has known for decades, that there is no evidence that foxes and cats were a major driver of Australia's mammal extinctions. Turns out there are quite a few issues here. Strap in for a looong thread πŸ§ͺ

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.

Heatmap distribution of invasive red swamp crayfish in Malta after the eradication attempt with the ERDF-funded ecological restoration project. We found invasive crayfish in their highest abundance within the excavated area.

[4/6] The outcomes of the restoration project had never been documented elsewhere, and mechanical excavation was not documented within scientific literature. So, how many important lessons and case studies are we losing from all these ERDF projects?

One of the goals of the project was to eradicate invasive red swamp crayfish (procambarus clarkii) by mechanically excavating the stream bed during the summer months. In total, over 53,000m3 of silt and sediment had been removed.

Summary statistics concerning the information available online about our stratified random sample of conservation-related (a) LIFE (n = 109) and (b) ERDF (n = 345) projects. Overall, ERDF 95% of our sample of LIFE-funded projects were found online with 61% being mentioned in peer-reviewed publications. There is no mention of most of our sample of ERDF-funded projects (68%) on Google's search engine and only 1% (n = 4) were mentioned in any peer-reviewed publications found on Google Scholar.
