Lovely link-up between @josephtobias.bsky.social's #Avonet and the #PredictsProject, with @nhm.org's @patrickawalkden.bsky.social among the authors

Although the title misses the point by a long way. It's not the "safety net for birds" that is at stake here, but the "safety net provided by birds" - the resilience of ecological functions supporting the whole ecosystem.

A useful News & Views accompanying the article - www.nature.com/articles/d41...
Land-use changes threaten the safety net for birds
Alterations in land use are found to leave bird communities with fewer backup species for key ecological roles, making ecosystems vulnerable to further species loss.

Land-use change undermines the stability of avian functional diversity - new #OA @nature.com paper with @patrickawalkden.bsky.social @josephtobias.bsky.social, combining #PredictsProject with #Avonet doi.org/10.1038/s415...
Land-use change undermines the stability of avian functional diversity - Nature
Large-scale analyses of bird species traits reveal that land-use change reduces resilience of key ecological functions more than previously thought.

Online now: Forecasting extinction risk for future-proof conservation decisions.

www.sciencedirect.com/science/arti...

Should conservation focus on threatened species? Or should we be proactive and protect species before they become threatened? This paper explores how to get the balance right.
Conceptual framework for extinction risk forecasting that outlines key elements and tradeoffs associated with forecasting on different time horizons.

This was an amazing workshop bringing together a wide range of perspectives. Thanks to the funders and everyone involved. Looking forward to next steps! 🌿🪶🌐

Our @sgn.one workshop organized together with @josephtobias.bsky.social and Susanne Fritz was enlightening, fun and will surely lead to many future interactions and outputs on how plant/animal traits translate into functions. Thanks to all for your excellent ideas and very respectful discussions! 🌐

PhD up for grabs in applied ecology focusing on species traits and ecological processes, supervised by @jmbecologist.bsky.social @orlyrazgour.bsky.social, Ben Woodcock, and me.
Worth a look!

PhD opportunity!

Focusing on ecological processes offers an adaptive approach to conservation at a time of rapid environmental change

But how do we measure & conserve these processes?

This PhD will explore the use of species traits to assess ecosystem condition

Wutt!? New ecosystem service just dropped.

Birds are fungi dispersers! And, even better, tapaculos are truffle dispersers!

One of the highlights of a short trip to Yunnan last week – the Spot-breasted Parrotbill: an icon for functional morphologists, an insectivore with the 'wrong' beak (stubby like a seed-eater) which nonetheless makes ecophysical sense because it uses bite-force to snip through grass/bamboo stems

New study from Ty Loft’s PhD thesis. We used an energetic approach to quantify, acr sub-Saharan Africa, how mammal- and bird-mediated ecosystem functions have changed. We found that overall trophic energy flows have decreased by more than one-third, but this change varies across biomes and land uses

A long and busy week ended on a high yesterday. So proud of Dr @jyang19.bsky.social for sailing through her PhD viva, the final step of a long journey in my lab from a Silwood masters degree to a doctorate. 💪

Big thanks to Profs Cris Banks-Leite and Gavin Thomas for examining.

A heads-up for anyone interested in research quality, repeatability & transparency: I'm leading a 2-hour session at 10 am UK-time tomorrow, in conjunction with others.
Hopefully this can form the basis of a guidelines paper, so we're hoping you can join online to guide us in the right direction. 🌐🌎

We have a new paper developing methods for looking at bird-fire macroecology. What’s most fascinating to me is that the magnitude *and* direction of fire effects can vary enormously across a species range. Stationarity is dead!! Long live non-stationarity!!

Confused writing is usually a symptom of confused thinking. As we struggle to clarify writing, we clarify our thoughts. AI writing aids rob us of that struggle, leaving clean-looking text and thoughts still confused for lack of inspection. Writing is not just a product; it is a diagnostic tool.
