5Trade-offs between wood production and forest grouse habitats in two regions with distinctive landscapes显示文摘Background:Forest management affects the viability of forest grouse populations,causing alterations to habitat quality.At the regional level,common targets for wood harvesting and safeguarding of specific habitats are negotiated between various stakeholders.Analysing potential trade-offs between forest grouse habitats and wood production in the region could support resource-smart decision making.Methods:In this paper,we compiled trade-off curves represented as production possibility frontiers demonstrating the relationship between forest grouse habitat area and wood removal,using a Finnish forestry dynamics model and the Finnish Multi-Source National Forest Inventory.For the modelling of forest grouse habitats,a landscape-level occurrence model based on nationwide wildlife triangle census data was used.Five alternative forest scenarios in terms of wood removal were compiled for two study areas in Finland representing two different landscape structures.Results and conclusions:Results showed that impacts on forest grouse habitats were case-specific.In the southern study area,increasing the roundwood harvesting rate affected grouse habitats more strongly as forests were already fragmented for other land uses and became more spruce-dominated over time.If the maximum sustainable removal rate was implemented,predicted grouse habitat area was 55%less than in a no-removal scenario.In the eastern study area,a more heavily forested region,the decrease was far lower at 22%.Scenario results were also compared to levels of recorded(business as usual)wood removal and that envisaged by valid regional forestry programmes,and their sustainability in terms of grouse habitat area was discussed.The production possibility frontiers calculated in this study support the evaluation of the loss of suitable habitat caused by different wood harvesting rates,or vice versa,the economic cost of increasing habitat areas.Helena Haakana Esa Huhta Hannu Hirvelä Tuula Packalen 2020Forest Ecosystems2020,7,2:1

13Survival of transplanted nests of the red wood ant Formica aquilonia (Hymenoptera: Formicidae): The effects of intraspecific competition and forest clear-cutting显示文摘蚂蚁殖民地的健康和幸存在他们的巢附近取决于资源。这些资源可以由于差的产地质量或由 intra- 和种间的比赛被限制,在极端,情况可以引起它蚂蚁殖民地死亡。我们由移植红木头蚂蚁的 26 个巢在殖民地幸存上测试了 intraspecific 竞争和产地降级(森林 clear-cutting ) 的效果(福米加 aquilonia 欧蓍草, 1955 ) 在包含了 0-11 的 26 个不同森林区域,同种的侨民每公顷嵌套。F。aquilonia 高度依赖于华盖住所蚜虫,因此,树的移动应该引起食物限制。在 4 年的实验的功课期间, 9 个森林部分是清晰的。当森林 clear-cutting 显著地减少了时,我们发现了那 colonies’幸存, intraspecific 竞争。作为一高度多花柱并且 polydomous 种类, F。aquilonia 似乎容忍到某个程度的相异的同种的殖民地的存在。Jouni Sorvari Esa Huhta Harri Hakkarainen 2014Insect Science2014,21,4:1
