Fascinating paper on something I never thought of: When we remove big old animals from wild populations (like fish) we might be losing important cultural transmission in species that learn from elders - Essentially culling transmission of collective knowledge onlinelibrary.wiley.com/doi/10.1111/...

Overfishing Social Fish

Social learning is common among vertebrates, including fish. Learning from others reduces the risk and costs of adaptation. In some longer-lived species, social learning can lead to the formation of ...

Heard of "Darwin's paradox"? It refers to Charles Darwin's observation that coral reefs are wildly productive despite occurring in nutrient-poor tropical oceans. Reefs are, so the story goes, oases in marine deserts 🏝️... Turns out that 2/3 of these assertions are very wrong... 🌐 🦑🧪 🧵⬇️

🚀 New paper led by Dr Becks Spake! We make the case for precision ecology—using big data & predictive tools to tailor conservation actions to local contexts. Can ecology learn from medicine & marketing to boost impact? We think so. Read it here: rdcu.be/eoaR4 #Conservation #Ecology #BigData

Precision ecology for targeted conservation action

Nature Ecology & Evolution - The fields of medicine and marketing use large data volumes and computational power to target individuals. This Perspective argues that applied ecologists should...

Was just asked to review a non-political research grant proposal to a call funded by 2 countries whose politics I don’t support. Tricky to decide whether to accept the task or not. Thoughts?

One of the most important things you can do today is your science. Knowing calculus/physics/genetics/chemistry etc. makes you rare and the world will need you to rebuild tomorrow. Practice your skills and pass them on. Keep the flame alive. 💚🌱🧪

Our new Nature paper on the multi-dimensional contributions of small scale fisheries just dropped www.nature.com/articles/s41.... We find that SSF supply ~40% of global fish catch worth >$77billion, with knock on benefits that support numerous sustainable development goals. A truly monumental effort

Illuminating the multidimensional contributions of small-scale fisheries - Nature

A study aimed at revealing the role of small-scale fisheries in sustainable development shows they provide at least 40% of the global fishing catch and affect the livelihoods of 1 in 12 people in the ...

Atlantic herring is one of the most abundant fishes in the world. In two new studies, we show that some herring in the Baltic Sea have become fish eaters. These piscivorous herring are genetically unique, grow fast, and play an important role in regulating stickleback populations.

Piscivorous herring – a unique fish in the Baltic Sea ecosystem | slu.se

In the coastal areas of the Baltic Sea, unusually large herring are sometimes caught, which has long raised questions. Are these large herring a separate population, or are they individuals that ha...
