And to capture even more light ...something amazing happens
As summer fades, reindeer eyes also change colour, to deep blue which further enhances the animals vision, helping it to see in dramatically different light levels
Look at this leaf visibly producing oxygen as bubbles in the water as it continues photosynthesis
Half of the world's oxygen is produced by phytoplankton, the other half is produced by trees, all the more reason to look after our forests and seas 1/
This is a nuclear reactor start up, you are seeing the core when the chain reaction becoming self sustaining.
The control rods are pulled up & as they are removed the number of fission reactions is increasing...1/
The water acts as a moderator in the reaction process as well as a coolant.
This fissioning of atoms creates heat that later generates steam to produce electricity. 2/
And this in the video is not a commercial reactor but a research and test one
Can you see that vibrant green defiant patch? That part is kept alive by the larvae of leaf mining insects, and even though its long fallen off the tree it’s still photosynthesising.
After hatching, the larvae tunnel through into the leaf protected from predation and the plants own defences and eat leaf tissue creating little visible tunnel patterns 2/
these insects pass from generation to generation a certain bacteria that manipulates the leafs own signalling chemicals – hormones called cytokinins. These usually do many tasks preventing a leaf dying 3/
The Golden Tortoise Beetle (Aspidimorpha sanctaecrucis) gets to stroll around looking beautiful in the rainy seasons of south east Asia but in its larval stage things were less glamorous... but extremely interesting read on .. 1/

2/ In its larval stage their defence mechanism is a faecal shield or faecal parasol, which it uses as a weapon if threatened.

Even more bizarre if there is multiple larvae they form a pyramid with shields facing outwards and of mum is still around she places herself on top Like this cutt.ly/ab4Sk4R
Reindeer Cyclones are a real thing... a swirling mass of threatened reindeer stampeding in a circle making it impossible to target an individual.. here the fawns are in the middle
This herd is on Russia’s Kola Peninsula, in the Arctic Circle
The video was originally posted on the Facebook page of the Museum of Anthropology and Ethnography Peter the Great, aka Kunstkámera, located in Saint Petersburg, Russia.
The video is worth watching to the end also here’s some reading cutt.ly/px5zQYq
