On the Role of Theory in Biology
Biology is often seen as an experimental science, with theory serving to generalize patterns from empirical data. But history reveals that theory plays a more generative role in discovery itself.

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.

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

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
