K Tubby et al.
European forests are threatened by increasing numbers of invasive pests and pathogens. Over the past century, Lecanosticta acicola, a foliar pathogen predominantly of Pinus spp., has expanded its range globally, and is increasing in impact....
The complexity of biological disturbance agents, fuels heterogeneity, and fire in coniferous forests of the western United States [0.03%]

David C Shaw et al.
Forest biological disturbance agents (BDAs) are insects, pathogens, and parasitic plants that affect tree decline, mortality, and forest ecosystems processes. BDAs are commonly thought to increase the likelihood and severity of fire by conv...
Development of a universal height response model for transfer of Norway spruce (Picea abies L. Karst) in Fennoscandia [0.03%]
泛北极地区挪威云杉(Picea abies L. Karst)树高的通用生长模型的建立与发展

Mateusz Liziniewicz et al.
Norway spruce is a major industrial tree species in Fennoscandia and future productivity of the species must be secured by matching the variation in adaptation of the species with suitable sites for optimized performance. An appropriate tra...
Reducing rotation age to address increasing disturbances in Central Europe: Potential and limitations [0.03%]

Forest disturbance regimes are intensifying in many parts of the globe. In order to mitigate disturbance impacts a number of management responses have been proposed, yet their effectiveness in addressing changing disturbance regimes remains...
What drives the future supply of regulating ecosystem services in a mountain forest landscape? [0.03%]
驱动山区森林景观调节生态系统服务未来供给的因素有哪些？
Rupert Seidl,Katharina Albrich,Karlheinz Erb et al.
Rupert Seidl et al.
Forest ecosystems provide a wide variety of ecosystem services to society. In harsh mountain environments, the regulating services of forests are of particular importance. Managing mountain forests for regulating services is a cost- and lab...
Looking beyond the mean: Drivers of variability in postfire stand development of conifers in Greater Yellowstone [0.03%]
均值以外山火后杨松林分的发展及其驱动因素分析——以美国大黄石地区为例

Kristin H Braziunas et al.
High-severity, infrequent fires in forests shape landscape mosaics of stand age and structure for decades to centuries, and forest structure can vary substantially even among same-aged stands. This variability among stand structures can aff...
Overwintering behavior reduces mortality for a terrestrial turtle in forests managed with prescribed fire [0.03%]
越冬行为可降低受控火烧森林中陆龟的死亡率
John H Roe,Zachery Bayles
John H Roe
Prescribed fire is an essential management practice in pyrogenic ecosystems, but fire can also be a significant disturbance and source of mortality for both target and non-target species. Seasonal periods of animal inactivity may provide op...

Forests and their ecosystem services are subjected to uncertain factors, causing drastic changes in forest production and/or market conditions, the impacts of which cannot be precisely estimated beforehand. We introduce a theoretical framew...
The impact of tree canopy structure on understory variation in a boreal forest [0.03%]
冠结构对北方森林林下层变化的影响

Titta Majasalmi
Information on understory composition and its relationships with the overstory tree canopy, especially leaf area index (LAI), is crucially needed in, e.g., modeling land-atmosphere interactions and productivity of forests. There are also se...
Basal area growth, carbon isotope discrimination, and intrinsic water use efficiency after fertilization of Douglas-fir in the Oregon Coast Range [0.03%]
施用化肥后 douglas 松基础面积生长、碳同位素分馏和固有水分利用率的研究——以美国俄勒冈海岸山脉为例

Eladio H Cornejo-Oviedo et al.
Many hectares of intensively managed Douglas-fir (Pseudotsuga menziesii Mirb. Franco) stands in western North America are fertilized with nitrogen (N) to increase growth rates, but only about ⅔ of all stands respond. Understanding the mech...
