Journal ArticleDOI

Increased atmospheric vapor pressure deficit reduces global vegetation growth

Wenping Yuan, +25 more
- 01 Aug 2019 - 
TL;DR: The results highlight that the impacts of VPD on vegetation growth should be adequately considered to assess ecosystem responses to future climate conditions.
Journal ArticleDOI

Estimating near-infrared leaf reflectance from leaf structural characteristics

Michèle R. Slaton, +2 more
- 01 Feb 2001 - 
TL;DR: The relationship between near-infrared reflectance at 800 nm from leaves and characteristics of leaf structure known to affect photosynthesis was investigated in 48 species of alpine angiosperms and showed that measured NIRR was highly correlated with A(mes)/A, leaf bicoloration, and the presence of a thick leaf cuticle.
Journal ArticleDOI

Leaf Form and Photosynthesis

William K. Smith, +4 more
- 01 Dec 1997 - 
TL;DR: The structural features of leaves have been associated with metabolic type (e.g., Kranz anatomy of C4 species), amount of sun exposure, or water stress as mentioned in this paper, but only recently has any functional relationship between leaf form and photosynthetic performance been suggested.
Journal ArticleDOI

Conifer seedling distribution and survival in an alpine-treeline ecotone

Matthew J. Germino, +2 more
- 01 Oct 2002 - 
TL;DR: Both spatial and temporal patterns of seedlingsurvivalsuggest that exposure to high sunlight may exacerbate low-temperature andwater stress in young conifer seedlings, inhibiting their establishment in this alpine treeline.
Journal ArticleDOI

Another perspective on altitudinal limits of alpine timberlines

William K. Smith, +3 more
- 01 Nov 2003 - 
TL;DR: A conceptual model of timberline migration is described that invokes a strong dependence on ecological facilitation, beginning with seed germination and continuing through seedling establishment and sapling growth to the stage where trees with forest-like stature form new subalpine forest at a higher altitude.
