Soil life supports the functioning and biodiversity of terrestrial ecosystems. Springtails (Collembola) are among most abundant soil arthropods regulating fertility flow energy through above- belowground food webs. However, global distribution springtail diversity density, how these relate to fluxes remains unknown. Here, using a dataset representing 2470 sites, we estimate total biomass at 27.5 megatons carbon, which is threefold higher than wild vertebrates, record peak densities up 2...
Springtails (Collembola) inhabit soils from the Arctic to Antarctic and comprise an estimated ~32% of all terrestrial arthropods on Earth. Here, we present a global, spatially-explicit database springtail communities that includes 249,912 occurrences 44,999 samples 2,990 sites. These data are mainly raw sample-level records at species level collected predominantly private archives authors were quality-controlled taxonomically-standardised. Despite covering continents, most come European...
Although partial harvesting has been proposed as a measure for maintaining compositional and structural characteristics of natural old-growth stands, it not rigorously evaluated. The first objective this study was to compare forest composition after killing portion canopy trees cuts in boreal mixedwoods eastern Canada by disturbances. second evaluate the effectiveness harvest treatments meeting silvicultural objectives increased growth residual stems advances regeneration. Higher densities...
Atmospheric acid deposition is of major concern in the Athabasca Oil Sands Region (AOSR) northern Alberta, Canada, which home to third largest oil reserve world. After decades sands production AOSR, potential impact on forest health, including tree growth and understory biodiversity, still not clear. We evaluated relationship modelled/interpolate atmospheric nitrogen (N), sulphur (S), base cations (BC), derived input (PAI) from surface mining with: (1) radial (i.e. basal area increment; BAI)...
The previous studies have reported maximum light levels at different positions within gaps but many of these are based on size. objective this study is to evaluate the influence gap size and position distribution in under canopy north a mixedwood temperate forest. For three sizes, with widths ranging between 0.5 1.5 times height surrounding stand, was measured along north-south axis each using two techniques (hemispherical photographs instantaneous measurements). In small gaps, most close...
Understanding processes driving mortality in forests is important for comprehension of natural stand dynamics and informing disturbance-based ecosystem management. There has been considerable study during the self-thinning phase but we know much less about stands at later successional stages. We addressed this through five 1-ha spatially explicit permanent plots mature (111-186 yr old 2012) Pinus contorta Canadian Rocky Mountains using data from repeated measurements over a 45-yr period,...

Here, using a dataset collected from 2,470 sites, we estimate total biomass at 29 Mt carbon (threefold higher than wild vertebrates 6 ) record peak densities up million...
Even though understory plant communities play important roles in northern forest ecosystems, our understanding of their long‐term successional dynamics and the associated driving processes is still limited. This study used spatially explicit data from five, long‐term, permanent plots mature lodgepole pine ( Pinus contorta ) stands Canadian Rocky Mountains to: (1) assess whether showed homogenization over time either within or between if compositional changes observed were supportive initial...
Abstract Question What are the processes driving regeneration and successional pathways in Pinus contorta subsp. latifolia Douglas ex Loudon forests? Location Canadian Rockies, Alberta, Canada. Methods We used five 1‐ha long‐term permanent plots, dendrochronological stand reconstruction detailed spatial analysis of stem‐mapped data. Results Establishment shade‐intolerant species mainly occurred within 20 years post‐fire but important later recruitment these was observed drier primarily gaps...
For thousands of years Ɂedacho Kué (Artillery Lake, Northwest Territories) has been a key water crossing site for barren-ground caribou (Rangifer tarandus groenlandicus). Human disturbance habitat in northern Canada emerged as an important focus study the last decade; particularly Bathurst range Territories where populations have declined by more than 95% since 1980s. Guided local Indigenous leaders and Elders, collaborative research project was developed with Dënesǫ́łıné people Łutsël K’e...
