Higher wind speeds are necessary to damage healthier trees. Fire, whether caused by humans or lightning, and related abiotic factors also affect the health of forest. The effects of man often alter a forest's predisposition to damage from both abiotic and biotic effects. For example, soil properties may be altered by heavy machinery.
Ecosystem diversity addresses the combined characteristics of biotic properties which are living organisms (biodiversity) and abiotic properties such as nonliving things like water or soil (geodiversity). It is a variation in the ecosystems found in a region or the variation in ecosystems over the whole planet.
A forest consists of many components that can be broadly divided into two categories: biotic (living) and abiotic (non-living). The living parts include trees , shrubs , vines , grasses and other herbaceous (non-woody) plants, mosses , algae , fungi , insects , mammals , birds , reptiles , amphibians , and microorganisms living on the plants ...
Competition is one of many interacting biotic and abiotic factors that affect community structure, species diversity, and population dynamics (shifts in a population over time). [3] There are three major mechanisms of competition: interference, exploitation, and apparent competition (in order from most direct to least direct).
The term "mixed forest" comes from the inclusion of coniferous trees as a canopy component of some of these forests. Typical coniferous trees include pines (Pinus spp.), firs (Abies spp.), and spruces (Picea spp.). In some areas of this biome, the conifers may be a more important canopy species than the broadleaf species.
Thus, tree trunks and branches can remain on the forest floor for long periods, affecting such things as wildlife habitat, fire behaviour, and tree regeneration processes. Some trees leave behind eerie skeletons after death. In reality these deaths are actually very few compared to the amount of tree deaths that go unnoticed.
Subadult male lion and female spotted hyena in the Masai Mara.The two species share the same ecological niche, and are thus in competition with each other. Interspecific competition, in ecology, is a form of competition in which individuals of different species compete for the same resources in an ecosystem (e.g. food or living space).
In the case of wide and/or overgrown borders, some species can become restricted to one side of the border despite having the ability to inhabit the other. Sometimes, the edge effects result in abiotic and biotic conditions which diminish natural variation and threaten the original ecosystem. Detrimental edge effects are also seen in physical ...
