This paper explores to what extent recovery trajectories of trees after drought events are related to acclimatization conveyed by ecological stress memory and proposes strategies to disentangle post-drought acclimatization from impairment.

This paper presents the results of the first analysis of global patterns of variation in individual-tree R:S. It is hypothesized that individual R:S varies with environmental conditions, namely climate and management type, and is also determined by intrinsic factors, namely tree size and species....

This letter discusses two related concerns: (1) the integration of experimental data from the field of plant hydraulics into traditional, comparative wood anatomy; and (2) the reversibility of evolutionary transitions between perforation plate types that form a continuum. The paper concludes that...

The monotypic genus Psilamonocolpites Mathur (1966: 40) was established to classify a new species of gymnosperm's pollen fossil, within the informal taxon Ginkgo-group, from Western Kutch, in India. Psilamonocolpites longicolpatus Mathur (1966: 40), collected in Paleogene Suppratrappean sediments...

This paper explores the potential of woody tissue photosynthesis in trees to counter the effect of drought stress. As woody tissue photosynthesis can play a crucial role in the local production of carbohydrates, compensating for the reduced long-distance carbohydrate transport from the leaves to...

A new species of Casearia is described from Coastal Lowland Forest and Sub-montane Forest in the states of Paraíba and Pernambuco. The new species is morphologically most related to Casearia souzae R. Marquete & Mansano, being distinguished by its leaf, sepals and ovary without glands, leaf...

Chimonocalamus elegans, a tentatively endemic new species of temperate woody bamboos from Northern Thailand is described and illustrated. The new species differs from other members of Chimonocalamus by its glabrous nodes, culm leaf sheaths with narrow apex (3-4 mm) and 4-7 mm long ligules.

The dead foliage of scorched crowns is one of the most conspicuous signatures of wildland fires. Globally, crown scorch from fires in savannas, woodlands and forests causes tree stress and death across diverse taxa. The term crown scorch, however, is inconsistently and ambiguously defined in the...

This paper explores the misconception concerning xylem embolism and discusses the functional and ecological significance of the hydraulic safety margin. The paper suggests the necessity to quantify the variation of safety margin within species, as the populations growing at species' warm/dry range...

This paper presents a new framework that brings together the effects of pathogens and drought on the water and C economy of trees, and explores the implications for the process of drought-induced mortality. The presented framework sets the ground for predicting the role of pathogens on tree...
