Remote sensing and spectroscopy of lichens
We analyzed and summarized which lichen species or genera, and in which habitats and geographical regions, have been remotely sensed, and which remote sensing or spectroscopic technologies have been used. We found that laboratory or in situ measured spectra of over 70 lichen species have been reported to date.

Percoll ミツド コウバイ ヲ モチイタ エンシンブンリ ニヨル イシクラゲ ノ サイボウガイタトウ (EPS) ジョキョ サイボウ ノ タンリホウ [PDF]
陸生ラン色細菌のイシクラゲ(Nostoc commune)は南極や日本にも生育する汎存種である.イシクラゲの細胞の周りに存在する細胞外多糖(EPS)は,水分保持や細胞の保護に役立つと共に遮光性物質を蓄積しており,これが苛酷な環境への適応に重要な役割を果たしていると考えられている.南極産の貴重なイシクラゲを材料にしてこの仮説を検証するためには,EPSを除去した細胞を高収率で回収する必要がある.そこで,これまでに報告のあるEPS除去方法を改良し,Percollを用いた遠心分離で細胞の回収率向上を図った ...
