I lift the lid on the oceans & census the life hidden beneath by combining Darwin’s toolbox–of natural history field guides, thermometer, microscope, and dissection kit–with big-data approaches @earth2ocean.bsky.social

We know a lot of people are choosing to boycott AI overall, and we support that. AI is terrible on the environment! At the same time, we understand many people still use AI tools. If you’re going use AI please delete the ChatGPT app, and switch to Claude by Anthropic instead.

‘I love midges because I know what their hearts look like’: is the passion for taxonomy in danger of dying out?

This is an important step forward in species distribution modelling, enabling researchers and policymakers to better understand marine biodiversity patterns and develop more effective conservation strategies.

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."

Interesting pre-print "A Framework for Questionable Research Practices in Ecological Modelling". I tend to agree with the statement in the screenshot re data-driven modelling decisions. 🌎🌐🧪 ecoevorxiv.org/repository/v...

Healthy and sustainable fisheries have lower carbon emissions and fuel use, because fish are more abundant and easier to catch with less effort. Rebuilding fisheries and ensuring that fleet sizes are appropriate for catch level, are keys for CO2 reduction
