Thanks for the tag brother.
That place looks magical the weed must be too…

Cool bro! Glad you found a copy. Within pages, you’ll be asking yourself what I’ve gotten you into! 
Hope you enjoy your ‘Walk’!

Yes i found a french version new and unused, popular book that’s cool. I already think I know more or less what to expect but i look forward Eric Newby’s experience with all mystic and animist vibes there and from Indus old times protohistoric move too. So for ten years that I’ve been interested in it and since my reproductions of Yarkhun landrace imported by my french friend Mriko i adapted to the encounter with the Yeti lol! Cheers bro!

Haa, haa, haa! Well, Newby has a ‘unique’ writing style and does a great job telling the story with English self-depreciating humor. I’ve never seen an “Illustrated” copy before. I did find some interesting old documents and maps of their trip when searching.
Hey, did any of the Thai beans arrive? No sign of JLB yet. And check w/Michael too!

Indeed not illustrated french version i think, will see when it will land in my hands the next few days in fact.
No postal sign here too, pretty long! Patience bro!

Hi Roms, @argylia here. Copied from the icmag thread…very interesting topic!
"I was reading about trait changes across altitudinal/elevation gradients in Southern Andes, very similar to North Pakistan. At least in Phacelia secunda they talk about dwarfism, bigger size (radial?), longer leaf pubescence’s, and more circular leaves (less foliar area… less water and heat loss).
In the second study they compare P. secunda with Dandelion. Different ways to cope with altitude.
I would love to see what happens if a dwarf phenotype and a “equatorial like” phenotype gets cultivated at high altitudes (over 3500 m asl.). Do both becomes dwarf? dwarf phenotype has more advantage than the equatorial type?
Cheers,
argylia"

Hey nice first post @argylia hola amigo and thanks for the move here, glad to see these studies thank you again!
Well i think that the dwarfism also exists in tropical or equatorial sativa. It’s like less pronounced i would say but the original altitude situ must be related.
For example here’s pheno/geno variation i found in Swazi Red :
The indica transformation combines high North hemisphere latitude and not only altitude in fact so i think that if a pure indica from 37°N move to South hemisphere highlands in Colombia, Peru or Chile the leaves and resin should become more sativa. So better to talk about indica instead of dwarf i think.
All is always relative so it’s not obvious to describe differences but i think that the size, shape, density and chemistry of trichomes is the key to study the latitude/altitude transformation in cannabis.
Not surprising and easier to make hasch with pure indica because its bigger tritri fall on their own ^^
Kenavo Argylia!

Yeah… mine bad, I didn’t take into account the climate.
Highlands of Colombia, Peru and Chile vary a lot. High humidity, massive winter rainfall, very dry and hot-cold (day-nights).
Ah, when I mean dwarf/dwarfism, I mean really small and chunky, like creeper or prostrate plants (no more than at least 1 m tall.)
There are some authors like Christian Körner, among others, who, of course, talk about it being multifactorial, but that more than anything it is the temperature that determines dwarfism in an altitudinal gradient (since the plants are closer to the ground, which is warmer [or has less thermal variation than the air]), according to him (and others) the low height would be given by that and by the low temperatures at higher altitudes, growing slower in a growing season (before the rains/snows). What they do not consider in depth is the effect of UV on height, or of other wavelengths. Bruce Bugbee has some studies on how certain lengths (which in the field vary with altitude) shape plant morphology.
And this is where I get lost… What I posted above is supposed to be about Phacelia secunda, there is also an example about dandelion, but we don’t know what’s really going on with Cannabis, whether its coping strategies with altitude are more morphological (changing leaf area, increasing leaf thickness, more trichomes) or physiological (anthocyanins and other secondary metabolites, antifreeze…) or maybe both. Perhaps in countries where it is still illegal, an alternative would be to use closely related species such as hops, or phenotypically plastic species such as Phacelia secunda (wide altitudinal range from approx. 300 m asl (close to 60 cm tall) to 3900 m asl (5 cm tall and very radially extended).
I feel that these are more bits of data and open questions than answers, but I hope to provide feedback to the discussion. I love this topic!
Cheers

Yea temp, UV and less atmospheric pressure too 
Life and biology is full of paradoxes so not easy to balance the understanding, step by step, trichome by trichome. cheers bro!

Hi again, hope you are doing well!
I had this somewhere in my files. Very interesting, only lab data, but, there are other studies (Italy) under sunlight.
This is a study of UV (elevation like) and Cannabis morphology:
…It is worth remembering that they are only looking at the effect of light and UV radiation. With elevation other variables come into play that could affect the morphology and production of secondary metabolites.
Cheers!
