News Items from April 2020

I have started a new topic for shared News Items.

This morning, having risen earlier than usual, I listened to The Extinction Tapes on BBC radio.
As usual I heard info previously unknown to me.

Today was the story of the demise of the Steller’s Sea cow - and it emphasised once again that, in biology, simplicity is not often the rule. Interference in the ecosystem has knock-on effects. Gottlieb Fichte said it in 1800 “you could not remove a single grain of sand from its place without thereby … changing something throughout all parts of the immeasurable whole”; he wasn’t the last to notice.

Thank you JoC - too early for me - but now I can follow the link.

Tree Kangaroos are rare; this short video seems to describe a win-win situation, which is also rare.

Thanks for your continuing new items here JoC

A new way to tweet?

Possibly one reason they are changing their tune is that their old tune can be very annoying, having spend many months doing fieldwork surrounded by them I can tell you that the tune can drive you to distraction at times!

Sounds like they finally got sick of it themselves.

À la recherche du temps perdu…I don’t suppose I am the only one here who spent Saturday mornings at the NHM children’s club (were we called the jackdaws - something ornithological I seem to remember).

When I went there the elphants stood in the entrance Hall. Years later I made a visit - and they were gone. Devastated.

Algae turns Italian Alps pink, prompting concerns over melting http://www.theguardian.com/world/2020/jul/06/algae-turns-italian-alps-pink-prompting-concerns-over-melting

When I was a student we were told that red snow was caused by Chlamydomonas nivalis. When I see red snow, which is fairly often, like today in fact, I used to say That’s Chlamydomonas nivalis. Having read this article I see that is not the whole truth.

As I have a picture taken of red snow today, I am posting it with some more info that I have read.

That is interesting, am sure I have seen pinkish snow but never thought to photograph it.

Hi MikeD,
if you have time to look at the Red Snow post I have made, I’d be grateful for a response to my question there as to why I cannot choose an id which appears in the Texanomy Browser, but not in the dropdown id box availalbe in Add Observation. I’ve edited the post link into my forum post above.
Thanks

Today’s google (at least in France) is
