The problem is that there seems to be no logical reason to draw the line at dogs, or sparrows or mice or insects, or, for that matter, trees or rocks.
Not that it mattered: "Tree of Life" won the Palme d'Or award at Cannes, and later picked up a Best Picture nomination at the 84th annual Academy Awards.
The study was a full factorial experiment with 3 levels of organic matter removal (tree boles only; tree boles + logging slash; tree boles + logging slash + forest floors) and 3 levels of soil compaction (0, 2, 4 cm impression), with a tree species split-plot of lodgepole pine (Pinus contorta) and hybrid white spruce (Picea glauca × engelmannii).
"We do that for free, no matter whose tree it is," Mr. Stern said.
The C pools in the soil organic matter and tree biomass together comprised more than 95% of ecosystem C stocks.
Understanding the impact of a variety of known and biologically plausible environmental irritants and triggers among children in New Jersey – ozone, fine particulate matter (PM2.5), tree pollen, weed pollen, grass pollen and ragweed – would allow for informed public health interventions.
Whereas my research focused on the fate of allochthonous organic matter (principally tree leaves) in streams, my tangential interests wandered into the isotope lab next door where I learned to use bomb fallout tritium as a groundwater tracer and 18O/16O isotope ratios to trace seasonal snowmelt water and the organic carbon it carries through shallow groundwater discharging into streams.
The gray matter of tree rats adds a certain sweetness generally absent from an otherwise bland backwoods diet.
A few species also eat plant matter; The tree frog Xenohyla truncata is partly herbivorous, its diet including a large proportion of fruit, Leptodactylus mystaceus has been found to eat plants, and folivory occurs in Euphlyctis hexadactylus, with plants constituting 79.5% of its diet by volume.
But they'll dine on vegetable matter from trees.
