Growth adaptability and foreign gene stability of TaLEA transgenic Populus simonii × nigra

Key message Late-embryogenesis-abundant proteins (LEA) typically accumulate to high levels during seed dehydration and have an important role in the plant response to abiotic stresses. Transgenic hybrid poplars of 9-year-old TaLEA lines showed adaptation to drought and

Multi-attribute decision making and geographic information systems: potential tools for evaluating forest ecosystem services

Key message Due to social and environmental changes over the last decade, managers use multi-attribute decision-making techniques and geographic information systems to support participatory planning. Several studies have indicated that the combined use improves forest planning by

Interaction of drought and frost in tree ecophysiology: rethinking the timing of risks

Key message The increase in climate variability is likely to generate an increased occurrence of both frost-induced and drought-induced damages on perennial plants. We examined how these stress factors can potentially interact and would subsequently affect the

Integration of field sampling and LiDAR data in forest inventories: comparison of area-based approach and (lognormal) universal kriging

Key message We compared (lognormal) universal kriging with the area-based approach for estimation of forest inventory variables using LiDAR data as auxiliary information and showed that universal kriging could be an accurate alternative when there is spatial

Changes in the non-growing season soil heterotrophic respiration rate are driven by environmental factors after fire in a cold temperate forest ecosystem

Key message During the non-growing season, environmental factors changed after fire, leading to significantly increased non-growing season soil heterotrophic respiration (Rh) and potentially decreasing the amount of net C stored in cold temperate forest ecosystems of China.

Low effective population size and high spatial genetic structure of black poplar populations from the Oder valley in Poland

Key message The genetic resources of black poplar in the Oder River valley are still substantial compared to those reported for rivers in Western Europe. On the other hand, clear signals of isolation by distance and genetic

Cold and heat tolerances of hybrids for restoration of the endangered Juglans cinerea L

Key message Hybrids had overall intermediate cold and heat tolerances compared to their progenitors, Juglans cinerea and Juglans ailantifolia. Differences in hybrids were small compared to J. cinerea though, indicating that when considering extreme temperature tolerances, hybrids

Genetic relationships between terminal shoot length, number of flushes and height in a 4-year-old progeny test of Pinus brutia Ten.

Key message In this study, genetic variation in polycyclic growth was investigated in a young Pinus brutia Ten. study in Turkey. The number of flushes was partially under additive genetic control and was moderately correlated with the

Leaf litter decomposition of deciduous Quercus acutissima Carruth. and evergreen Quercus glauca Thunb. in an inter-site experiment in three contrasting temperate forest stands in South Korea

Key message Local climate exerted a stronger effect on leaf litter decomposition of deciduous Quercus acutissima Carruth. and evergreen Quercus glauca Thunb. than initial leaf litter quality: the decomposition was much faster for leaves of the two

Assessing spatial and temporal dynamics of a spruce budworm outbreak across the complex forested landscape of Maine, USA

Key message Simulated spruce budworm (SBW; Choristoneura fumiferana (Clem.)) defoliation generally becomes ubiquitous in 3 years after its initiation in agreement with historical observations despite varying environmental and stand conditions over large ranges. Current-year defoliation has almost
