来自雅库特永冻土生态系统的研究人员针对常绿灌木北极熊果 (Arctostaphylos uva-ursi)开展光系统II (PSII)冷适应机制研究。通过OJIP叶绿素a荧光动力学曲线分析，发现低温驯化过程中QB-和QA-非还原中心比例增加，电子传递活性 (ETО/ABS)受限，PSII供体侧失活程度 (FK/FJ)持续升高。在+5°C至-10°C温度范围内 ...

推荐：研究人员通过调查加州圣巴巴拉县Point Sal和Burton Mesa混合种群中熊果属 (Arctostaphylos)的杂交潜力，发现原归为A. rudis的Nipomo Mesa种群在遗传和形态上独立。结合ddRADseq和形态学分析，证实其为新种A. nipumu，并因栖息地破碎化被列为保护优先物种。
