There is much need to develop strategies to secure ecosystem services via primary productivity and to prevent the continued loss of biodiversity.
This Research Topic wills to provide an up-to-date account of knowledge on plant competition with a focus on identifying the mechanisms underpinning competitive ability. The Research Topic aims to showcase knowledge that links ecological relevance with physiological processes to better understanding plant and ecosystem function. We welcome articles featuring original research as well as reviews, opinions, and new methods. Important Note : All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements.
Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review. With their unique mixes of varied contributions from Original Research to Review Articles, Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area! Find out more on how to host your own Frontiers Research Topic or contribute to one as an author.
Competitive interactions over time manifest themselves in physical and behavioral adaptations that shape the evolution of a species. Human activity, invasive species, climate change, and environmental pressure are constant stressors on ecosystems, making resources less available and of less quality. These stressors affect the way that organisms compete with each other and their ability to survive and co-exist. These Nutches have troubles, the biggest of which is The fact there are many more Nutches than Niches.
If an animal in a given habitat has a similar ecological niche to another species, how would direct competition influence their interactions? What possible outcomes could there be if an exotic species is accidentally introduced to a stable, mixed-bird community?

Types of Competition A fundamental concept in ecology is the competitive exclusion principle. Forces of Competition Defensive Behavior When an animal has found a space that contains all the resources it needs to survive, it wants to hold on to it. Aggressive Behavior Animals exhibit aggressive behavior when one of their resources is compromised.
How to Avoid Competition- Isolate Yourself Nature is am amazing beast; it has mechanisms in place to allow species to exist in the same place at the same time using the similar resources. Geographic Isolation One method of isolation is geographic isolation- not being in the same place at the same time. Behavioral Isolation This occurs when animals have contradictory behaviors that prevent them from competing with each other.
Mechanical Isolation The lip morphology of rhinos is an evolutionary expression of a behavioral trait that separated rhinos long ago.
The Trade Off These rewards are not without consequence. Mixed seabird colony- great crested terns and brown boobies Kia Island, Fiji Competition as a Regulator When two organisms or populations compete with each other, whether it be directly or indirectly, one of several outcomes can be expected.
Foreign Contenders Sometimes competition can have a serious impact on an ecosystem, especially when invasive or exotic species are involved. Human Competition As the human population continues to increase, humans are in competition with nature. The Big Picture Understanding competition is a huge component of ecology.

But it is also possible that neither plant will grow much in such a competition. Another area of competition is in gathering available sunlight. Plants that grow rapidly and have big leaves may be able to gather sunlight at the expense of nearby, less aggressive plants. Some plants use other defensive tactics to prevent opponents from competing. Some put toxins in the ground nearby, so competitors cannot get too close.
There are plants that seek nutrients owned by another. Parasitic plants will compete with host plants for the host's nutrients. The parasite is on the offense, trying to take nutrients directly from the victim of the attack. The victim plant is on the defense, trying to fend off the attack and succeed in surviving. Although this seems like a one-sided competition, if the plant is able to prevent the parasitic plant from getting its nutrients, the parasite may wither and even die.
But if the host plant dies, the parasite may be in trouble and even die itself. Plants with sufficient nutrients, water, sunlight, and territory compete by their for reproductive ability. If the plants are in proximity and there is a limited amount of essential ingredients, a head-to-head competition for as much of a share as possible results.
