Characterizing woodland caribou habitat in sub-boreal and boreal forests
Woodland caribou (Rangifer tarandus caribou) are sensitive to changes in understory vegetation resulting from forest harvesting and are, therefore, of special concern for foresters and habitat biologists. Effective management of this species requires reliable habitat inventories which, because of the large heterogeneous areas over which caribou range, can be costly. We used Landsat Thematic Map...
متن کاملPhotosynthetic traits of Sphagnum and feather moss species in undrained, drained and rewetted boreal spruce swamp forests
In restored peatlands, recovery of carbon assimilation by peat-forming plants is a prerequisite for the recovery of ecosystem functioning. Restoration by rewetting may affect moss photosynthesis and respiration directly and/or through species successional turnover. To quantify the importance of the direct effects and the effects mediated by species change in boreal spruce swamp forests, we used...
متن کاملSpatially-explicit Modeling of Siberian Boreal Forests
Circumpolar boreal forests contain one half of the terrestrial carbon stores, and have been shown to be susceptible to climate change. As climate regimes shift, the total biomass and species composition may change in ways that may promote further warming on the regional level through atmosphere-vegetation feedbacks. The purpose of this project is to develop a spatially explicit model for simula...
متن کاملMethane measurements in Tropical and Boreal forests
Methane is a climatologically important greenhouse gas, which plays a key role in regulating water vapour in the stratosphere and hydroxyl radicals in the troposphere. Recent findings that vegetation emits methane have stimulated efforts to ascertain the impact of this source on the global budget. In this work, we present the re-5 sults of high frequency (ca. 1 min −1) methane measurements cond...
متن کاملRecycling of phenolic compounds in Borneo’s tropical peat swamp forests
BACKGROUND Tropical peat swamp forests (TPSF) are globally significant carbon stores, sequestering carbon mainly as phenolic polymers and phenolic compounds (particularly as lignin and its derivatives) in peat layers, in plants, and in the acidic blackwaters. Previous studies show that TPSF plants have particularly high levels of phenolic compounds which inhibit the decomposition of organic mat...
