In other words, coldness makes more water vapour. Thus, transpiration in the plant does not occur that much since the humidity is high and temperature is low. Thus, highlander neps have adapted to the cold and humid surroundings by reducing the rate of transpiration.
For those who do not really know what transpiration is for, it is to help the plant in reducing excess water and assist in the pull of absorbed minerals and water at the roots to the whole plant. It generally cools down the plant during a hot weather.
A highlander would literally dry to death if exposed to sudden lowland conditions. This is because they have adapted to the cooling surroundings that keep them cool. Highlanders would transpire too much water so that they can cool themselves to match the lowland conditions. Plus, low humidity encourages more transpiration.
Btw, it's nice to be back
