Premise of the Study The growth limitation hypothesis (GLH) and carbon limitation
hypothesis (CLH) are two dominant explanations for treeline formation. The GLH proposes …

Although the growth limitation hypothesis (GLH) is the most accepted physiological
explanation for alpine treeline formation, the debate about its formation mechanisms still …

Key message A ratio of storage to growth of at least 8.4 and a balanced storage-growth
relationship might be essential for subalpine larch trees to persist at the treeline. Abstract …

Environmental factors that drive carbon storage are often used as an explanation for alpine
treeline formation. However, different tree species respond differently to environmental …

Low temperatures are associated high‐altitude treelines, but the functional mechanism of
treeline formation remains controversial. The relative contributions of carbon limitation …

Key message The treeline on Changbai Mountain controlled by low temperature and water
stress, has not reached the position most commonly expected. Abstract Treeline pattern is …

Many studies have tried to explain the physiological mechanisms of the alpine treeline
phenomenon, but the debate on the alpine treeline formation remains controversial due to …

As trees and shrubs approach the high elevation tree limit, it is often assumed that they fall
short in photosynthate (source limitation). Alternatively, low temperature may restrict carbon …

Abstract Background and Aims The most plausible explanation for treeline formation so far is
provided by the growth limitation hypothesis (GLH), which proposes that carbon sinks are …

Carbon allocation in tree stems critically affects how trees respond to climate variability and
extreme weather. However, it is difficult to directly measure nonstructural carbohydrates in …
