Very happy to share that our paper presenting a framework for optimal movement decisions in complex landscapes has just been published in TREE @stephharris.bsky.social @jacobnabe.bsky.social tinyurl.com/d45s36y5

💡 We are writing a systematic review article about physical properties of light and attractiveness to seabirds in the Norwegian Arctic and are in need for some benchmark literature to evaluate our systematic search! Can anyone help? Please share 💡

High deer densities are one of the main challenges in temperate forest restoration and management. But not all deer are the same! In this review we consider the evidence for their impacts on woody vegetation ->
The number of studies reporting the occurrence of each deer species, together with the different effects on woody vegetation that were studied. Note that the numbers in this matrix add up to more than the total number of studies (n = 455), as many studies reported more than one deer species present and more than one effect category.

How do different deer species affect woody vegetation? Understanding that not all deer are the same is essential to effective forest management and restoration. 🧪🌏 Summary thread below ->

Fallow deer diet in North Wales is dominated by bramble (Rubus fruticosus agg.) across seasons 🦌

Bramble is important not just for pollinators but also for deer! 🦌 Our new paper published this week used faecal DNA metabarcoding to study the diet of fallow deer in North Wales, and used preference analysis to compare whether plant taxa were used more or less than expected given their abundance.

What do deer eat in the winter? In the UK a common assumption is that they subsist on over-wintering crops or grazing land. In our new paper led by Amy Gresham we overturn that story. 1/7 besjournals.onlinelibrary.wiley.com/doi/full/10....
Graphical abstract for Gresham et al. (2025). Full abstract: A DNA metabarcoding study of the diet of fallow deer (Dama dama) in North Wales has revealed a dominance of bramble Rubus fruticosus agg.) in the diet across seasons. The diet was significantly less diverse in winter compared to other seasons. As we work to expand tree cover and enhance woodland resilience and biodiversity in the United Kingdom amid climate change and emerging diseases, we should seek to understand the dynamic interactions of increasing deer populations with rapidly changing treescapes.

New paper out today led by Amy Gresham exploring fallow deer diet using metabarcoding. Results were very different to what we expected!
