Negative effects of forest edges and canopy opening on moth communities

Forest Ecology and Management
Forest loss and fragmentation are major threats to biodiversity and associated ecosystem services worldwide.Forest fragmentation leads to the creation of forest edges, which experience contrasting environmental conditionscompared to forest interiors ...

Open forest ecosystems: An excluded state

Forest Ecology and Management, 2020
Abstract Once dominant but now largely excluded from eastern North America, open forests of savannas to woodlands occupy the ecosystem gradient between grasslands and closed forests. These fire-maintained systems differ in structure, processes, and species from closed canopy, succession-driven forests that currently dominate this region.

Patch size of forest openings and arthropod populations

Oecologia, 1991
Five sizes of canopy openings (0.016 ha to 10 ha) were established in the Southern Appalachian Mountains in early 1982 to examine the initial patterns of plant and arthropod establishment across a size range of forest disturbances. Vegetation standing crop after the first growing season was considerably higher in large than small openings in apparent ...

Forested and Open Wetland Complexes

1992
In northern Sweden 3.8 million ha of the land surface is covered by mires, while another 1.7 million ha consists of moist or wet forest (i.e. forests with a high water table) (Svensson et al., 1989). The area occupied by wet forest, particularly the damp, shady type of late successional spruce, is steadily being reduced as a result of various forest ...

Soil heat flux measurements in an open forest

Physics and Chemistry of the Earth, 1996
The soil surface heat flux in an open oak forest was determined at four locations to account for the heterogeneity of the forest. Soil temperatures and soil water content were measured at several depths and an integration method with three layers was used. The thickness of the bottom layer was determined with a spectral method.

GPS moving performance on open sky and forested paths

2007 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2007
In this paper we present a systematic study of the performance of seven different configurations of GPS on a moving vehicle using three different GPS receivers. The seven different configurations are 1) single frequency code differential DGPS, 2) double frequency code differential DGPS, 3) RTK-GPS receiving RTCM correction from a mobile phone, 4) RTK ...

Forest opening issues in Croatia

1998
The paper deals with problems of Croatianforest opening and of attempts to increase the road density during the period 1991-1995. About 80 percent of Croatian forests and forest land are state forests. the public enterprise Hrvatske šume manages this national resource with its 16 Forest administrations.
