Sentences with phrase «forest density with»

This can be reconciled with the effects at other levels by taking into account increases in leaf number and reductions in forest density with age.

Not exact matches

One confounding factor, cautions geographer Margaret Skutsch of the National Autonomous University of Mexico, Morelia, is that many remaining indigenous territories are in remote, humid tropical forests with low population densities, meaning that lack of development pressure, rather than effective management, may explain why such forests have remained standing.

Polish scientists worked to protect the least spoiled area of forest with the greatest density of big trees, first as a nature reserve and then as a national park in 1932.

Using advanced three - dimensional forest mapping data provided by the Carnegie Airborne Observatory (CAO), integrated with satellite imaging data, the team was able to create a map of carbon density throughout the 128 million hectare (320 million acre) country of Peru, at a resolution of one hectare (2.5 acres).

Whereas chips with horizontal racetracks alone could out - compete flash memory, creating «forests» of vertical racetracks on a silicon substrate would yield three - dimensional memory chips with data - storage densities surpassing those of hard drives, Parkin says.

For example, forest elephants in Central Africa occur in densities seven times higher in sites with ecoguards than without them.

A forest is an area with a high density of trees (or, historically, a wooded area set aside for hunting).

Results show clearly that forest elephants were increasingly uncommon in places with high human density, high infrastructure density such as roads, high hunting intensity, and poor governance as indicated by levels of corruption and absence of law enforcement.

In this case, shifts in song could either evolve and become fixed or simply be adjusted accordingly by individuals, with functional significance such that signal transmission is optimized in a new environment (e.g. differences in plant density in different forests).

Maximum density values are strongly correlated with April to August mean temperatures in trees across the boreal forest from Alaska to Labrador, Schweingruber et al., (1993)...

Kelp forests are underwater areas with a high density of kelp.

The second is a pure landscape except for a lone figure traversing the forest, in a strongly expressionist work rendered in a fall palette, with a density not unlike that of a tropical rain forest.

While the forests are «fire adapted», these areas could be managed to co-exist with human development if lower tree densities were maintained and housing and landscaping were designed for greater fire resistance.

Figure 1: Twenty - year smoothed plots of tree - ring width (dashed line) and tree - ring density (thick solid line), averaged across a network of mid-northern latitude boreal forest sites and compared with equivalent - area averages of mean April to September temperature anomalies (thin solid line).

Gains result from forest growth; losses result from deforestation and from reductions in carbon density within standing forests (degradation / disturbance), with the latter accounting for 68.9 % of overall losses.

With respect to why there was a significant increase in tree density over the past several decades, Dolanc offers that the changes in the density and composition of lower - elevation forests are consistent with fire suppression; but that the density increases in high - elevation vegetation types (subalpine forests generally don't burn) are «more likely to be caused by changing climate.&raWith respect to why there was a significant increase in tree density over the past several decades, Dolanc offers that the changes in the density and composition of lower - elevation forests are consistent with fire suppression; but that the density increases in high - elevation vegetation types (subalpine forests generally don't burn) are «more likely to be caused by changing climate.&rawith fire suppression; but that the density increases in high - elevation vegetation types (subalpine forests generally don't burn) are «more likely to be caused by changing climate.»

Furthermore, forests with the greatest density of carbon might not be the most essential locations for biodiversity conservation.

Maximum density values are strongly correlated with April to August mean temperatures in trees across the boreal forest from Alaska to Labrador, Schweingruber et al., (1993)...

The study, based on overlaying maps of proposed oil palm development with maps showing carbon - density and wildlife distribution in Kalimantan (Indonesian Borneo), estimates that REDD is financially competitive, and potentially able to fund forest conservation, with oil palm at carbon prices of $ 10 - $ 33 per ton of carbon dioxide equivalent (tCO2e).

For example, Schweingruber et al. (1993) showed that maximum density values were strongly correlated with April - August mean temperature in trees across the entire boreal forest, from Alaska to Labrador, whereas minimum and mean density values and ring widths had a much less consistent relationship with summer temperature at the sites sampled (D'Arrigo et al., 1992).
