In honour of "Postdoc Appreciation Week", a plug for a paper I was involved in 5 years ago (w/ @bjmjarrett.bsky.social, @muriellealund.bsky.social and others) in which we highlighted how academia could better support postdocs. There is much here that remains relevant! www.nature.com/articles/s41...

The postdoctoral experience is in need of reform. Here the authors outline concrete steps that institutions, postdocs and mentors can take to improve the landscape.

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.

Large wild fauna are a natural part of, and crucial to, most ecosystems, performing all sorts of key roles. Early humans killed off most planetary megafauna, and that artificial absence has many enduring negative effects. Follow @jcsvenning.bsky.social for more on this. (3) bsky.app/profile/jcsv...

Hi both, yes we had a theory that bramble was acting as a winter survival resource, as it has persisted despite the long term heavy deer browsing in these woods. Could be an energy saving strategy to stay put and use this resource instead of foraging more widely in winter?

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.

With increasing disturbance from extreme weather and tree diseases leading to a more open canopy structure, bramble cover is set to increase in European forests, which could support further expansion of deer populations.

... whilst widespread taxa (e.g. Rosa sp., Prunus sp. and Quercus sp.) were consumed more often than expected, given their availability in the landscape. In contrast to broadleaved trees and shrubs, conifer trees were found in very few samples.

Amy Gresham (she/her) @amygresham48.bsky.social · 10/02/2025
Broadleaf trees became more prevalent in the diet in the spring and summer, with oak being most prevalent in autumn, probably due to acorn consumption. Spatially clustered taxa (e.g. Betula sp., Corylus sp. and Fraxinus sp.) were consumed less often than expected ....

Amy Gresham (she/her) @amygresham48.bsky.social · 10/02/2025
In fact, we found that the deer were consuming bramble (Rubus fruticosus agg.) more than any other taxa. Rather than diversifying their diet in winter as expected, the diet diversity was actually lowest in winter, with bramble forming 80% of the diet.

Amy Gresham (she/her) @amygresham48.bsky.social · 10/02/2025
We studied the diet of fallow deer in North Wales to understand how they may be impacting local woodlands. We expected the diet would be dominated by grasses supplemented by woody browse in the winter, as this species is typically characterised as an opportunist bulk grazer.
