Das denkende Insekt - Hummeln lösen Probleme wie Primaten
Eine Hummel sitzt in einem Versuchsaufbau aus Plexiglas. An der Decke hängt eine blaue Kunstblume mit Zuckerlösung — zu weit oben, um sie direkt zu erreichen. Auf dem Boden liegt ein Ball. Die Hummel ...

City-Maut in NewYork: Autofahrer müssen 9 Dollar bezahlen, wenn sie nach Manhattan einfahren. Die Stadt nahm damit 500 Millionen Dollar ein. Der Pkw-Verkehr sank um 11 %, während die Besucherzahl in Manhattan und die Umsätze in den Läden stiegen. 👍 #Verkehrswende www.sueddeutsche.de/meinung/stre...
Den Städten bleibt keine andere Wahl: weniger Autos, mehr Busse und Bahnen
Wer den ÖPNV nicht mit ausreichend Geld ausstattet, sabotiert die Funktionsfähigkeit der Ballungszentren.

Een vreedzame machtswisseling in de grootste chimpanseepopulatie ter wereld eindigt in een gewelddadige breuk. Jaren van conflicten volgen, met tientallen doden. De studie laat zien hoe snel sociale spanningen kunnen ontsporen. Lees meer: bionieuws.nl/grootste-chi...

New paper alert: >80k nacelle-height recordings and stereo-thermal 3D tracks show that bats sing in the rotor-swept zone and circle turbine nacelles. We need smarter, species-sensitive curtailment that aligns both climate and biodiversity goals. #Bats #Conservation 🔗 doi.org/10.1038/s420...

New preprint: an undergrad in my lab Stella DiPippo tested out vivio-morpholinos as a means for transient targeted knockdown of gene expression in adult threespine #stickleback. It worked, but a bit inconsistently. A useful start testing a new method for this species www.biorxiv.org/content/10.6...

One last little fun fact: Emily Williamson (née Bateson), founder of the RSPB was Melissa’s great, great aunt! It looks like a love of birds may run in families… 😉 🐦 6/6
The last 2 years, Melissa has been working with the other trustees to increase the professionalisation of ASAB operations, as well as advocating for open science practices, such as pre-registration in animal behaviour. It’s not easy being president & she has done a wonderful job so far 🤗 5/6
As president, Melissa also needs to make decisions (but not about foraging). She chairs ASAB council and is also a trustee financially responsible for the charity, the law of which is quite complex. She also gets the far more fun job of handing out awards!... 4/6
There are also some ecological parallels between humans & starlings: both are invasive, omnivorous and opportunistic. Looking at foraging decisions & food unpredictability in starlings, including physiological, developmental & cognitive effects, can give us insight into human food insecurity... 3/6
This #MeetASAB features Madam President herself: Melissa Bateson (@melissabateson.bsky.social) Melissa was elected as ASAB president in 2024. In the past, she has also been on council as grants secretary and as an ordinary member. She has been an ASAB member since she was a PhD in the 90s… 1/6

Does selection favor the most limnetic source lake genotypes in limnetic recipient lakes? And favor the most benthic source lake genotypes in benthic recipient lakes? um... No. Instead, certain source lakes seem to *always* win at selection regardless of the habitat they are introduced into
New preprint from our big collaborative evolution experiment in 9 whole lakes in Alaska, written by McGill grad student @lucaseckert.bsky.social www.biorxiv.org/content/10.6... What happens if you put a mixture of multiple source populations together to complete & evolve in multiple new lakes?
Monet avoided outlines, believing they betrayed light. For him, form existed only where light revealed it.
