چکیده
Old-growth forests are optimal habitats for many woodpeckers, which often themselves excellent indicators of deadwood-associated biodiversity. are, however, heterogeneous ecosystems in terms structure, composition, and deadwood characteristics, thus implying a varied use these by woodpeckers. In boreal landscapes, old-growth stands threatened forest harvesting; there is little information regard to the consequences biodiversity with loss specific types forests. This study aimed assess how black-backed woodpecker (Picoides arcticus), indicator species associated attributes, uses different its foraging needs. We identified marks 24 eastern Canada that were dominated black spruce (Picea mariana), located within home range eight various using typology based on structural attributes stands. classified sampled into four types, corresponding successional stages (recent or old, relative onset stage), composition (pure mixed spruce–balsam fir [Abies balsamea]), productivity (ongoing paludification not). The foraged all forests, but favored dense not paludified showed high temporal continuity (i.e., dynamics probably started more than century ago). state allows continuous supply large, slightly decayed snags, preferred substrates woodpecker. type most this is, also targeted first logging operations. Protecting recent managed areas requires maintaining sufficient area density dense, spruce-dominated areas.

Mycorrhizal fungi supply nitrogen to host plants in Arctic tundra and boreal forests: 15N is the key signal.
Symbiotic fungi's role in providing nitrogen to host plants is well-studied in tundra at Toolik Lake, Alaska, but little-studied in the adjoining boreal forest ecosystem. Along a 570 km north-south transect from the Yukon River to the North Slope of Alaska, the 15N content was strongly reduced in ectomycorrhizal and ericoid mycorrhizal plants including Betula, Salix, Picea mariana (P. Mill.) B....
متن کاملProtected Area as an Indicator of Ecological Sustainability? A Century of Development in Europe’s Boreal Forest
Protected area (PA) is an indicator linked to policies on ecological sustainability. We analyzed area, size, and categories of PAs in the European boreal forest biome in Norway, Sweden, Finland, and Russia from 1900 to 2010. The PA increased from 1.5 × 10(3) ha in 1909 to 2.3 × 10(7) ha in 2010. While the total PA in the boreal biome was 10.8 %, the figures ranged from 17.2 % in the northern, 7...

متن کاملEcological Uses of Vertebrate Indicator Species: A Critique
Plant and animal species have been used for decades as indicators of air and water quality and agricultural and range conditions. Increasingly, vertebrates are used to assess population trenak and habitat quality for other species. I n this paper we review the conceptual bases, assumptions, and published guidelines for selection and use of vertebrates as ecological indicators. We conclude that ...
