It would be closer to an irregular Voronoi pattern. "A certain distance" is imprecise, it would have to be "regular" intervals to give a lattice/matrix. For trees that grow at the same rate, a square grid arrangement would give square canopy shapes. A triangle lattice would give triangles and honeycomb would give honeycomb canopy units. For trees that ...


For most trees and plants, distribution is spatially highly variable. Thinking about the lifecycle of plants—their seeds are non-randomly dispersed, the seedlings and saplings grow in different biotic (neighboring trees, distance to herbivores) and abiotic (different soils, shading, etc.) environments, all the plants are at different life/size stages, and ...


It's to do with the chemistry taking place in the system, and then in turn the balance of energy resources. Leaves contain chlorophyll, a molecule that traps light energy. It is large molecule containing a long carbon chain and a magnesium atom surrounded by 4 nitrogen atoms. In terms of a plants energy resources it is an 'expensive' molecule, but it is ...


It looks like a white crab apple or an obscure cultivar of apples, of which there are many. The best identifier will be the fruit. Because there are not millions of flowers, It looks like there may be less fruit and bigger than a crab apple, although it varies by year. The fruit of crab apples are small apples which can be used to make jelly. Crab apple ...


The tree grew its first fruits this spring, so that I could definitely identify it: it is a goat willow! This is consistent with its spontaneous sprouting in my yard, as it is a common tree in my region.


This phenomena has elements of what, in the UK, are termed Phoenix Trees, however this term, and the term Phoenix Regeneration, is more often used when describing characteristics of ancient and veteran trees. The principles that underlie what the photo shows is that new growth on trees will always grow strongest where there is the most light available, and ...


Speaking specifically about blueberry bushes as a perhaps extreme example, they thrive in acidic soil and nitrogen-laden soil. However, dog urine is bad for blueberries, as the high nitrogen content overwhelms the plant and damages fruit production. Dog urine is only slightly acidic (pH 6-6.5) and can often be alkaline, which also changes the soil acidity in ...
