What is diffuse competition?
Diffuse competition implies that native species in the community also compete among themselves. Diffuse competition has been documented in the context of native species competing among themselves in diverse communities (Keddy 2001).
What are diffuse interactions?
A diffuse relationship means that a third species alters the interaction between the other two. In this sense, diffuse evolutionary interactions are not simply synonymous with multi-species interactions.
What is meant by competition between plant species?
Competition is generally understood to refer to the negative effects on plant growth or fitness caused by the presence of neighbors, usually by reducing the availability of resources. Competition can be an important factor controlling plant communities, along with resources, disturbance, herbivory, and mutualisms.
What are the competition in natural communities?
Competition is a relationship between organisms that strive for the same limited resources. The resources might be food, nesting sites, or territory. Two different types of competition are intraspecific and interspecific competition. Intraspecific competition occurs between members of the same species.
What is temporal niche partitioning?
Conditional differentiation (sometimes called temporal niche partitioning) occurs when species differ in their competitive abilities based on varying environmental conditions. As a result, each species will have an advantage in some years, but not others.
What is fundamental realized niche?
Fundamental niche is the entire set of conditions under which an animal (population, species) can survive and reproduce itself. Realized niche is the set of conditions actually used by given animal (pop, species), after interactions with other species (predation and especially competition) have been taken into account.
Why do plants compete for competition?
Plants that are close to each other may compete for nutrients, water, sunlight, and territory necessary for survival. Some plants go mainly on the offense, trying to get as much as they can. Other plants use defensive methods to stifle their opponents from getting needed nutrients.
Why is competition important in plants?
Competition occurs above- and belowground. Competitiveness describes a key ability important for plants to grow and survive abiotic and biotic stresses. Under optimal, but particularly under non-optimal conditions, plants compete for resources including nutrients, light, water, space, pollinators and other.
What is the role of competition in a community?
Competition is an interaction between organisms or species in which both the organisms are harmed. Limited supply of at least one resource (such as food, water, and territory) used by both can be a factor. Competition both within and between species is an important topic in ecology, especially community ecology.
What are some causes of competition among plants?
What is temporal niche?
The “temporal niche” of a species is defined as the conjunction of these 24-h rhythms, whose timing is characterized by two basic parameters, the period and the phase. Furthermore, in most animals, locomotor activity rhythms may represent a reliable phase-marker of that animal’s master circadian clock.
What is spatial and temporal heterogeneity?
Temporal heterogeneity is the diversity of kind or arrangement of constituents across the time. Spatial heterogeneity refers to the diversity of kind or arrangement of constituents across space.
