Ester vs ether links: Why are archaeal cell membranes more resistant to high temperatures and acidity than bacterial and eukaryotic membranes?

The phospholipids composing the cell membranes of eukaryotes and bacteria contain ester links between the glicerol and the fatty acids. Archaeal membranes, instead, are composed of phospholipids containing ether links between a glicerol and an isoprene chain:

My microbiology teacher explained that these differences, mainly the ester vs ether links, were determinant to maintain the archeal membranes stable in environments with high temperatures and acidity, but she didn't go into much detail on why. I would like to know the specific chemical reasons why.


(Disclaimer: Considering I'm interested only in the organic chemistry involving this situation, and not in specific archeal phisiology or biology in general, I found it adequate to post this question here in the "Chemistry" cathegory.)
