Sustainable forest management is essential to confront the detrimental impacts of diseases on forest eco-systems.This review highlights the potential of vegetation spectroscopy in improving the feasibility of assessing forest disturbances induced by disea
Species composition,structure,regeneration,and management status of Jorgo-Wato Forest (JWF) was studied.Number of individuals,diameter at breast height (dbh) and height of woody species (dbh ≥ 2.5 cm) were counted and measured in each plot.Group discussio
Understanding how soil fertility changes due to environmental conditions and stand-age-dependent for-est attributes is important for local-scale forest restoration.We evaluated the effects of stand-age-dependent forest attributes (plant community composit
The distribution of many plant species has been shaped by climate changes,and their current phenotypic and genetic variability reflect microclimatically suitable habi-tats.This study relates contemporary climate to variability patterns of phenotypic trait
Airborne laser scanning (ALS) has been widely applied to estimate tree and forest attributes,but it can also drive the segmentation of forest areas.Clustering algorithms are the dominant technique in segmentation but spatial opti-mization using exact meth
蜂胶是意大利蜜蜂或无刺蜂的工蜂在采集树木表面的树脂或分泌物的同时将其与自身上颚腺和蜡腺分泌物充分混合加工,而形成的一种不规则不透明且具有芳香味的纯天然褐色胶状固体物质.其有效成分具备抗菌、抗氧化等的生物学活性,应用领域为广泛.系统综述了蜂胶在医药保健品、疾病防御、食品保鲜、日用化工产品、植物保护、畜禽水产的饲料、农业和畜牧业相关疾病控制等方面的应用,还总结了蜂胶的利用形式,如蜂胶浸膏、蜂胶合片和蜂胶软胶囊等,为广大蜂农和蜂业工作者对蜂胶产品的利用与开发提供参考.
Both climate and land-use changes,including the introduction and spread of allochthonous species,are forecast to affect forest ecosystems.Accordingly,forests will be affected in terms of species composition as well as their soil chemical and biological ch

The biodiversity of natural or semi-natural native,old oak woodlands have high conservation impor-tance,especially in landscapes of monocultural forest plan-tations and arable fields.With a wider variety of microhabi-tats and foraging sources,such old oak
Investment in silvicultural techniques is notice-ably lacking,especially in breeding programs for non-con-ventional wood species.Studying genotype × environment interaction (G × E) is essential to the development of breed-ing programs.Thus,this study aime
