We are excited to be recruiting a number of new postdoctoral researchers working across a range of topics from biodiversity modelling and creative future visioning to cultural understandings of biodiversity and game design.

PDRA positions at Leverhulme Centre for Anthropocene Biodiversity (York, UK)
These include four that I am involved with:
beta diversity change
ecosystem metrics
ecological monitoring & Indigenous and local knowledge
food system dynamics & biodiversity

Clarity of targets and definitions is vital in the maximisation of positive synergies and minimsation of negative trade-offs. This includes acknowledgement of the political and human aspects in order to move forward.
In this piece we argue that resilience need to be defined explicitly and should focus on processes rather than species identity and composition. In a rapidly changing world a return to or retention of past stages is no guarantee of resilience in socio-ecological systems.
What is resilience for a landscape? Check out our (with Charles Cunningham, @hannalp.bsky.social, Lauren Barnes, Chris Thomas and @janehillyork.bsky.social ) new paper now out in @peopleandnature.bsky.social Early View @anthropocenebio.bsky.social

🧩Human modification does not always lead to a biotic homogenisation.
Using a scenario-based approach, we found that beta diversity increased despite reductions in local alpha diversity, thereby maintaining gamma diversity, when relatively natural landscapes were modified into mixed landscapes.
This study used five very different case studies but there is still much more to be explored.
This challenges the view that widespread species are the main drivers of biotic homogenisation. Our work also suggests that conservation interventions to increase localised species occurrence are likely to have the most impact on limiting homogenisation.
Our results were also influenced by the level of nestedness found within the set of assemblages.
By comparing the trends in individual species occurrence to their beta-diversity contributions we found that the most widespread species directly contributed very little to beta-diversity change. The main influence was found to be the balance of declining versus increasing rare species.
New paper with @jonathan-gdon.bsky.social @cmbeale.bsky.social and Chris Thomas looking at species contributions to biotic homogenisation and differentiation.

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

The Greatest Extinction Event in 66 Million Years? Contextualising Anthropogenic Extinctions

@jackhhatfield.bsky.social @anthropocenebio.bsky.social
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
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

Seven for a secret never to be told….
Great to see my first Beefly of the year today! #BeeFlyWatch
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

We are still recruiting Brazilian experts in species ID at Pivotal. It's remote flexible work so a really handy side gig.
If you can identify Brazilian plants or mammals from photos, of frogs, bats or birds from audio, please apply! 🧪

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?
