Abstract Large old trees are important ecological entities in human settlements, providing cultural values and ecological services that are threatened by current and future changes in global climate, land use and disturbance regimes. Some studies suggest incorporating social and cultural significance into the conservation of large old trees.

Read the free Plain Language Summary for this article on the Journal blog. Abstract The biotic resistance hypothesis (BRH) of Elton posits that diverse communities are more resistant to biological invasions. While the effects of climatic stresses and human disturbances on community invasibility have been extensively studied individually, their combined

Mechanisms on Mangrove Ecosystem Degradation from Waves by Boats [PDF]
通过分析波浪在林内和光滩上传播途径,阐述了船舶引起的频繁巨浪造成红树植物死亡、林内动物种群和数量减少、滩涂断层及红树植物难以自然扩展等生态系统退化机理;在此基础上提出消除和减少船舶兴波对红树林生态系统危害的有效对策。In this paper,different paths of wave spreading in the bare mudflat and vegetated areas were analyzed,and damages from boat-generated waves to ...

Read the free Plain Language Summary for this article on the Journal blog. Abstract In the Southwest Australian Biodiversity Hotspot, the greatest plant species diversity tends to occur on the most phosphorus (P)‐impoverished soils. Many plant species in this P‐impoverished environment release root carboxylates that mobilise soil P which is a more ...

Assessing limits of sustainable seed harvest in wild plant populations
Abstract Seed harvesting from wild plant populations is key for ecological restoration, but it may threaten the persistence of the source populations. Consequently, several countries have set guidelines limiting the proportions of harvestable seeds. However, these guidelines are inconsistent and lack a solid empirical basis.

Summary Environmental changes and their effects are among the most pressing topics of today's ecological research. Shrublands, although widespread across the globe, remain understudied in this respect. We conducted a global meta‐analysis of 81 shrubland sites subjected to experimental warming, shifts in precipitation (e.g.

Preliminary studies on effects of restored mangroves on coastal soils [PDF]
初步研究了不同林龄的再植红树林对海岸湿地土壤理化性质的影响。结果表明,红树林恢复对深层土壤(20~25cm)的影响强于表层(0~5cm);与光滩相比,红树林恢复对表层土壤的氧化还原性无显著影响,但导致20~25 cm土层氧化性增强;再植红树林对土壤营养盐有明显吸收作用,其中NH4+-N含量显著高于NO2--N 和NO3--N,为主要吸收营养盐,PO43--P含量虽与IN相当,但红树林对P的吸收并不明显;随着红树林恢复时间的延长(林龄增加),20-25 cm土层的pH值显著下降,红树林酸化作用增强 ...
