A model-based analysis of climate change vulnerability of Pinus pinea stands under multiobjective management in the Northern Plateau of Spain
By Erwin Dreyer On 27 September 2015 In Research paper
Climate change is likely to heavily affect the provision of goods and services of Mediterranean forests. Our results strongly point out the need to develop adaptive strategies to mitigate the impact of climate change in order to

50 years Annals of Forest Science: The response of tropical rainforests to drought—lessons from recent research and future prospects
By Erwin Dreyer On 27 September 2015 In Review paper
We review the recent findings on the influence of drought on tree mortality, growth or ecosystem functioning in tropical rainforests. Drought plays a major role in shaping tropical rainforests and the response mechanisms are highly diverse and

Tree rings reflect growth adjustments and enhanced synchrony among sites in Iberian stone pine (Pinus pinea L.) under climate change
By Erwin Dreyer On 27 September 2015 In Research paper
We used tree ring analysis to assess the response of Pinus pinea to climate change in South Iberia. Climate–growth relationships changed over time, with greater sensitivity in recent years due to increasing aridity. A common dendroclimatic signal

Integrating risk preferences in forest harvest scheduling
By Erwin Dreyer On 21 September 2015 In Non classé
Through a stochastic programming framework, risk preferences can be included in forest planning. The value of utilizing stochastic programming is always positive; however, the value depends on the information quality and risk preferences of the decision maker.

Transpiration of four common understorey plant species according to drought intensity in temperate forests
By Erwin Dreyer On 17 September 2015 In Research paper
Key message Water use patterns of understorey vegetation are species-dependent. Calluna vulgaris showed little or no regulation of transpiration in response to soil water depletion or air vapour pressure deficit, unlike Pteridium aquilinum, Rubus sp. and Molinia

Continuous planting under a high density enhances the competition for nutrients among young Cunninghamia lanceolata saplings
By Erwin Dreyer On 17 September 2015 In Research paper
A high-density plantation inhibited growth and biomass accumulation of Cunninghamia lanceolata (Lamb.) Hook. saplings, as well as their photosynthesis. This inhibition was enhanced in a soil that had been previously planted with the same species. The main

The pine shoot beetle Tomicus piniperda as a plausible vector of Fusarium circinatum
By Erwin Dreyer On 12 September 2015 In Research paper
The pine shoot beetle, Tomicus piniperda, is a potential vector of the pitch canker disease pathogen. The insect could transmit the pathogenic fungus during its maturation or regeneration feeding on the shoots of healthy pine crowns. Abstract

Irreversible diameter change of wood segments correlates with other methods for estimating frost tolerance of living cells in freeze-thaw experiments
By Erwin Dreyer On 12 September 2015 In Research paper
We assessed tree frost tolerance using electrolyte leakage and a method based on irreversible diameter change of branches. It was shown that irreversible diameter change correlates with electrolyte leakage and USDA hardiness rating and is a good

Phytochemical screening of the heartwood extractives of ten Congo Basin tree species
By Erwin Dreyer On 12 September 2015 In Research paper
Content and type of extractives vary considerably among woody species in the Congo Basin tropical forest. They influence the natural durability of wood with respect to fungal and insect degradation. Species containing higher amounts of extractives and
