In the taiga-tundra ecotone (TTE), site-dependent forest structure characteristics can influence the subtle and heterogeneous structural changes that occur across the broad circumpolar extent. Such changes may be related to ecotone form, described by the horizontal and vertical patterns of forest structure (e.g., tree cover, density and height) within TTE 10 forest patches, driven by local site...

Avian species persistence in a forest patch is strongly related to the degree of isolation and size of a forest patch and the vegetation structure within a patch and its matrix are important predictors of bird habitat suitability. A combination of space-borne optical (Landsat), ALOS-PALSAR (radar), and airborne Light Detection and Ranging (LiDAR) data was used for assessing variation in forest ...

Forest edges can strongly affect avian nest success by altering nest predation rates, but this relationship is inconsistent and context dependent. There is a need for researchers to improve the predictability of edge effects on nest predation rates by examining the mechanisms driving their occurrence and variability. In this study, we examined how the capture rates of ship rats, an invasive nes...

Interactions among endophytic fungi, woody plants and herbivores are usually studied emphasizing fungal mediated plant-herbivore interactions. Seeking evidence for indication of causal relationships between fungi and herbivores sharing the host plant has been self-feeding reasoning in endophyte literature since the findings that some endophytes, particularly seed-borne grass-endophytes in agron...

Estimation and mapping of forest resources are preconditions for management, planning and research. In this study, we applied kriging interpolation of geostatistics for estimation and mapping of forest stock at-tributes in a natural, uneven-aged, unmanaged forest in the Caspian region of northern Iran. The site of the study has an area of 516 ha and an elevation that ranges from 1100 to 1450 m ...

In this paper, we formally define a useful data structure for content-based routing and event delivery. The poset (partially ordered set)-derived forest data structure is induced by the partial order created by the covering relation between event filters. Two extensions of the basic data structure are discussed: colored forests and the weakly merging forest. We give performance figures for the ...

—The ability to assess the influence of site-scale forest structure on avian habitat suitability at an ecoregional scale remains a major methodological constraint to effective biological planning for forest land birds in North America. We evaluated the feasibility of using forest inventory and analysis (FIA) data to define vegetation structure within forest patches, which were delineated from i...

in large regions of the world, biomass is a very important source of energy. the global bioenergy market based on forest biomass is growing rapidly. about 92 % of the bioenergy in sweden comes from forests. biomass from forests is not homogenous. the locations, transport distances, and transport methods, can differ very much and the industries that need biomass as input prefer raw materials wit...

The structure of and growth forms and habits exhibited by the New Zealand rain forest are described and compared with those of lowland tropical rain forest. Theories relating to the frequent regeneration failure of the forest dominants are outlined. The floristic affinities of the forest type are discussed and it is suggested that two main elements can be recognized-lowland tropical and montane...

Because forest stand structure, age, and productivity can mediate the impacts of climate on quaking aspen (Populus tremuloides) mortality, ignoring stand-scale factors limits inference on the drivers of recent sudden aspen decline. Using the proportion of aspen trees that were dead as an index of recent mortality at 841 forest inventory plots, we examined the relationship of this mortality inde...
