To evaluate zirconium implant artifact production in cone beam computed tomography images obtained with different protocols.
Average parturition date of squirrels is highly variable from year to year (range of annual means: April 2 to June 6) and inversely correlated with cone production in the previous autumn (higher production-earlier breeding; Boutin et al. 2006).
Spatial and temporal variability in cone production may influence post-disturbance succession, yet it is not well understood.
The earliest onset of cone production was 1997, and early onset was associated with lower elevations (<2300 m).
Cone production in the young post-fire lodgepole pine stands that regenerated after the 1988 Yellowstone fires is both abundant and spatially variable, and lodgepole pine in this system might produce serotinous cones earlier than reported previously.
across a range of environmental conditions in subalpine forests of the Lake Tahoe Basin, California and Nevada, to determine how WPBR is influencing host fecundity (i.e., female cone production and recruitment), survival, and current population trends.
Identification of the mechanistic drivers contributing to spatial heterogeneity in Δ13C provides an opportunity to select seed sources better suited to optimize long-term survival, vigor and cone production.
latifolia) stands (n = 16) that regenerated naturally after the 1988 Yellowstone fires and varied in stand density (566 545,200 stems ha−1) and elevation to quantify and explain variation in cone production.
Finally, the results show that, on average, 7% of the estimated total income would be captured by the current System of National Accounts for forestry if applied to our case study (including only the net value added from timber and pine cone production and from plantation investment) and that 14% of this income would be dislocated into the government institutional accounts.
Cone production varies a great deal from year to year, but, as a result of its low flowering rate, is generally very low.
