What are the ecological effects of releasing and managing mallard ducks for hunting?
Our new OA paper with @ecoevoenviro.bsky.social authors.elsevier.com/sd/article/S...
What did we find? A short π§΅
Mallard release in the UK has been increasing over recent years and now ~1.3-2.6 million are released annually
Problems are likely to be especially acute (and benefits less) on large "driven duck only" days
We call for markedly more research into Mallard release and management
Evidence is currently limited and often weak (especially considering wider ecosystem effects)
Releases and associated management have both positive (e.g. habitat creation, feeding) and negative (e.g. interbreeding, disease, eutrophication) ecological impacts
Millions of Mallard are artificially reared and released annually across the world in UK, Europe and North America
We conducted a literature review (37 papers, 41 effects) of their genetic, direct & associated effects on wild conspecifics, other waterbirds and aquatic ecosystems

New paper out!
Early-life social instability increases aggression in chickens, but does not affect response inhibition π€
We discuss what this means for developmental links between social environments, cognition, and social behaviour, highlighting strong context dependence

Almost pheasants! A new review that we've contributed to looking at causes and consequences of ranging behaviour in reared chickens, led by @birgitszabo.bsky.social
Many chickens don't seem to want to use the additional space that they are offered. Can we change this?
Less than a week left to apply!
Rather feels like reading my obituary! π¬
But thanks Jen and Sophia for putting that togetherπ I really enjoyed working with the ASAB team and recommend any AB folk consider joining and contributing. Looking forward to Edinburgh for the winter meeting. See you there.

How robust is current hunting bag data, and can we rely on it to manage sustainable harvest of UK waterbirds?
For most species, it's pretty good, but released mallardπ¦π¦can confuse the picture

What are we talking about when we're talking about "cognition"?
Terminology in this field has become confused and confusing. While writing our recent review, we tried to structure terms for our own sanity, and provide a template in a Glossary

Why is the apparent link between cognition and fitness so weak?
Could it be that our proposed causal link between cognition, behaviour and fitness/selection is too simplistic and linear? We discuss possible alternative models
Studies that measured fitness as "survival" (survival to next season, mass gain, foraging success etc) were more likely to report sig relationships than those measuring "reproductive" fitness (attractiveness, provisioning levels, offspring production etc)
Studies that measured "broad" forms of cognition (innovation, problem solving) were more likely to report sig relationships than those measuring more "specific", defined forms (reversal learning, spatial memory etc)
