The diverse diaspora of CAM: a pole-to-pole sketch.
Holtum JAM. Holtum JAM. Ann Bot. 2023 Nov 25;132(4):597-625. doi: 10.1093/aob/mcad067. Ann Bot. 2023. PMID: 37303205 Free PMC article. Review.
BACKGROUND: Crassulacean acid metabolism (CAM) photosynthesis is a successful adaptation that has evolved often in angiosperms, gymnosperms, ferns and lycophytes. Present in ~5 % of vascular plants, the CAM diaspora includes all continents apart from Antarctica. ...In pere …

The Pressure Is On - Epiphyte Water-Relations Altered Under Elevated CO2.
Batke S, Holohan A, Hayden R, Fricke W, Porter AS, Evans-Fitz Gerald CM. Batke S, et al. Front Plant Sci. 2018 Nov 27;9:1758. doi: 10.3389/fpls.2018.01758. eCollection 2018. Front Plant Sci. 2018. PMID: 30538718 Free PMC article.
To improve our understanding of the whole-plant response of epiphytes to future climate change, we investigated for the first time both individual and combined effects of elevated CO(2) (560 ppm) and light on the physiology and growth of two epiphyte species [Tillandsia brachycau …

Differences in the photosynthetic plasticity of ferns and Ginkgo grown in experimentally controlled low [O2]:[CO2] atmospheres may explain their contrasting ecological fate across the Triassic-Jurassic mass extinction boundary.
Yiotis C, Evans-Fitz Gerald C, McElwain JC. Yiotis C, et al. Ann Bot. 2017 Jun 1;119(8):1385-1395. doi: 10.1093/aob/mcx018. Ann Bot. 2017. PMID: 28334286 Free PMC article.
Ginkgo was found to photorespire heavily under ambient conditions, while growth in low [O 2 ]:[CO 2 ] resulted in increased heat dissipation per reaction centre ( DI o / RC ), severe photodamage, as revealed by the species' decreased maximum efficiency of primary photochemistry ( …
