Adding up: ask yourself what happens when hypothetically we all adopt genAI, which is opaque by default, and someone pays whoever controls the algorithm to e.g cite trans people less. Because that's possible and I guarantee that it will happen. Then, what?

I think that a lot of talks in academia refuse to shy away from the classic "intro, methods, results, ..." format, and I think it's very limiting Talks aren't papers, and don't have to be structured like one! I've been trying out different presentation formats recently and it has been going well🧵

Thoughts on Pipistrelle Type D social calls -meaning and relevance.
An audiomoth passive audio detector was set to record most nights from 12th March to 12th November 2025 in a damp mixed deciduous woodland in North East England (Woodland Trust’s Hedley Hall Wood, NZ218559). A paper has been sent to the Editors of British Island Bats for consideration of publication in Volume 6. During the year both Pipistrelle species recorded also emitted type D social calls -antagonism/ resource protection/ advertisement (Middleton et al., 2022).
