Empty forest is a term coined by Kent H. Redford's article "The Empty Forest" (1992), which was published in BioScience. An "empty forest" refers to an ecosystem that is void of large mammals . Empty forests are characterized by an otherwise excellent habitat , and often have large, fully grown trees, although they lack large mammals as a ...
The question of if a tree falls in a forest has been used as a phrasal template, for example in Ken Robinson's TED talk in 2006: I saw a great T-shirt recently which said, “If a man speaks his mind in a forest, and no woman hears him, is he still wrong?”. [16]
The exact definition of what makes a place "uninhabited" is not simple. Nomadic hunter-gather and pastoral societies live in extremely low population densities and range across large territories where they camp, rather than staying in any one place year-round.
A vacant niche or empty niche is an ecological niche in a particular ecosystem that is not occupied by a particular species. The issue of what exactly defines a vacant niche and whether they exist in ecosystems is controversial. The subject is intimately tied into a much broader debate on whether ecosystems can reach equilibrium, where they ...
Often trees have a fixed (more properly, bounded) branching factor , particularly always having two child nodes (possibly empty, hence at most two non-empty child nodes), hence a "binary tree". Allowing empty trees makes some definitions simpler, some more complicated: a rooted tree must be non-empty, hence if empty trees are allowed the above ...
A forest is an undirected graph in which any two vertices are connected by at most one path, or equivalently an acyclic undirected graph, or equivalently a disjoint union of trees. [ 2 ] A directed tree, [ 3 ] oriented tree, [ 4 ] [ 5 ] polytree , [ 6 ] or singly connected network [ 7 ] is a directed acyclic graph (DAG) whose underlying ...
Secondary succession is the secondary ecological succession of a plant's life. As opposed to the first, primary succession, secondary succession is a process started by an event (e.g. forest fire, harvesting, hurricane, etc.) that reduces an already established ecosystem (e.g. a forest or a wheat field) to a smaller population of species, and as such secondary succession occurs on preexisting ...
