Titelbild der taz vom 22. Oktober. Sie zeigt zwei Frauen vor einem Olivenbaum. Dazu die Zeile: Ölkrise in Marokko. Der Klimawandel erschwert die Olivenernte. Wie marokkanische Bäuerinnen damit umgehen und was im neuen UN-Bericht zur Anpassung an die Erderwärmung steht

People should absolutely be writing about how ICE's occupation of their cities is transforming life in these places, and they should be publishing it in print on paper - not just social media posts. There needs to be a record of this. Things are changing in measurable ways for the worse every day.

Anyone thinking that having a car or two is ''quality of life'', should pay a visit to Paris to experience a city where a car is not only 'not necessary' but even a burden.
Paris was transformed by improving public transport, extending bike lanes, and by converting streets to green spaces. Amazing.

Strips of land planted with flowers are much loved: they are beautiful and attract bees and insects. Is that enough for #Biodiversity? Researchers call for more diversity and collaboration across the landscape: www.uni-goettingen.de/en/3240.html...

Photograph shows villages and rolling fields and blue sky far away in the distance. Most of the photograph is taken up by a wide, green, lush field in the foreground. In the middle is a broad strip of large, white daisy-like flowers (ox-eye daisies or Leucanthemum vulgare). Thanks to Bea Maas for the photograph.

While the prevalence of toxic agrochemicals in our food, water and urine tests is increasing,with known health impacts, and while the biodiversity crisis is accelerating, some agri ministers think that the best thing to do at the moment is to ease the route for approving agrochemicals.

Happy to share new work from the lab and a wonderful group of co-authors:

We argue that conservation biology needs to move beyond the current focus on species richness metrics.

While this has been argued before, we highlight the unappreciated impacts of using richness for a variety of problems:
Beyond Species Richness for Biological Conservation
Recent global policy developments have highlighted the need for straightforward, robust, and meaningful biodiversity metrics. However, much of conservation science is dominated by the use of a single....

a black/white checkerboard of insects from the Hymenopteran order which includes bees, wasps and ants, from top left to bottom right: - a blood red and black bee with orangey wings (on black) - a dark brown orange red and black hornet, looks kind of fuzzy (on white) - a tawny mining bee, really fuzzy with an orange thorax and yellow abdomen (on black) - a spider parasitoid wasp, tiny black with curly antennae and spikes on the legs (on white) - a light orange fire and with a tiny stinger protruding in the back (on black) - a bee with jewel like green eyes, light yellow and black stripes (on white) - extremely fuzzy bee, chubby leg warmers, wings folded on the back hiding the abdomen partially (on black) - a red velvet ant, which is actually a wingless parasitoid wasp, black legs, two black bands ont he abdomen and the rest is bright fuzzy red (on white) - a bright green head/thorax and grey/black abdomen sweat bee, covered in pollen particles (on black)

Wenn wir in den letzten Jahren eines gelernt haben, dann: Es gibt kein intellektuelles Niveau, das nicht unterschritten werden kann.
Auch Lanz stellt fest, dass in den USA „nach der Wokeness von links jetzt eine ganz harte Wokeness von rechts“ komme. Und die, ergänzt Precht, „werden all die Mittel nutzen, die die Wokeness von links zur Verfügung gestellt hat. Und das ist in erster Linie, andere möglichst öffentlich zu beschämen und Leute zu canceln.“ Sobald es Teil des gesellschaftlichen Umgangs miteinander sei, „dass immer irgendjemand angeprangert oder moralisch angefeindet wird, dann können die Rechten das alle übernehmen. Das ist das, was in den USA passiert ist. Und deshalb sage ich: Wehret den Anfängen!“

What are the consequences of pollinator decline for wild plants? Here we try to find out in @valor-project.eu. Interesting observations. I never see Centaurea jacea flowers with pollen. But keep the pollinators away and the flowers are dusted white. Very popular species.
