Thanks! Yes, I can imagine the volume is a problem and many people don’t change from the default CC-BY-NC. I’ll try and go again soon and fill you in a recording form.

Do you use records from iNaturalist? I went there and added a few during York City Nature Challenge. Also looks to be quite a few other records

This paper was a huge collaborative effort built from a workshop series bringing together ecologists and paleobiologists. I would like to thank all those that made it possible and funding from
@anthropocenebio.bsky.social

We know that human influence is global and systems are changing rapidly. The placing of current extinctions in context does not negate the need to address known issues many of which clearly impact the longer term prospects of the biosphere

The current event is still smaller however than events labelled mass extinctions such as that at the end of the Cretaceous. Much uncertainty remains around any of these comparisons. We therefore also discuss the issues of comparing different data and the need for multiple lines of evidence

The Greatest Extinction Event in 66 Million Years? Contextualising Anthropogenic Extinctions Species and ecosystems are changing rapidly in response to human actions, but how does this compare with the deeper past? We review and compare the current extinction event to those over the last 66 ...

In our new article just out we examine the current extinction event in the context of the longer fossil record. We conclude it is likely the greatest event in the last 66 million years

I’m aiming to increase my species count on @inaturalist.bsky.social by 500 this year so was great to see this amazing caterpillar on a recent trip to Exeter

Cat sat on a broadband cabinet

I often see this cat sat here on my way to work. Seems an odd spot but I think I’ve figured it out. The cabinet kicks out a fair amount of heat. Is this an example of individuals adjusting their behaviour to microclimatic conditions?
