We suggest three ways forward: • Monitor biodiversity outcomes alongside spatial targets like 30×30. • Require reporting of take status to the WDPA. • Incorporate biodiversity explicitly when designing MPAs. @sfugradstudies.bsky.social

Another major finding: Much of the reported MPA coverage comes from sites where take regulations aren't reported to the World Database on Protected Areas. Only about 34% of countries report take status for any of their MPAs, making it difficult to evaluate how much effective protection exists.

Marine Protected Areas (MPAs) are one of the main ways we protect the ocean, but an important question often goes unasked: How does global MPA coverage actually relate to species range coverage? We quantified MPA coverage across the national-water ranges of 1,158 species. @sfuscience.bsky.social

A screenshot of the 1st page of article entitled "A Framework for Questionable Research Practices in Ecological Modelling" and available at https://ecoevorxiv.org/repository/view/11855/. The text reads "Questionable research practices (QRPs) bias the published literature towards apparently strong and conclusiveresults, resulting in low rates of replicability. Recent metaresearch reveals that ecology is not immune tothe ‘reproducibility crisis’ seen in other disciplines, due to similar rates of QRPs and a lack of transparencyin published research. However, metaresearch to date focuses on hypothesis-testing research and treatsdata-dependent analytic decisions as inherently questionable. This is not a good fit for ecology and relatedfields that conduct exploratory or predictive research using complex models, where data-dependent decisionsare often necessary and legitimate aspects of the modelling process."
