experiment replicated seven times in the Coast and Cascade ranges of western Oregon, USA. This paper focuses on patterns observed 6 years following thinning. Early-seral cover was related to interactions among broad-scale variation in climate, intermediate-scale variation in insolation, and fi ne-scale neighborhood interactions. Late-seral species cover was related primarily to fi ne-scale neighborhood interactions. Furthermore, cross-scale interactions partially explained patterns of spatial correlation among neighboring subplots for early-seral species but not late-seral species. The authors hypothesize that residual patterns of spatial autocorrelation were related to unmeasured environmental variables for early-seral species and historical conditions (i.e., pre-treatment stand composition and structure) for late-seral species. Results suggest responses of understory plants to overstory density management depend on cross-scale interactions among environmental drivers, neighborhood-scale interactions, and species traits. Future demand for ecosystem services from terrestrial ecosystems from global power production scenarios to 2100: the role of forest biomass. Callesen, I.
The strategic importance of forest resources, both at the national and global level, as well as the scarcity of reliable qualitative and quantitative information about Brazilian forests are among the motivations that led to the implementation of a new national forest inventory in Brazil (IFN-BR). Beyond traditional field survey through clustered sampling, the IFN-BR incorporates Landscape Sample Units (LSU) as a geospatial component of the inventory. Landscape indicators and indices are generated through the analysis of land use/land cover in the LSUs, which provide information about composition, morphology, mosaic patterns, adjacent habitat similarity, connectivity, fragmentation, and state of riparian zones. In the current study, we describe the indicators selected to assess landscape using pilot LSUs established in Paraná State, as well as the calculation and composition of indices and scores.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
