Soil food web

Bdthetfo:

The ''[[soil]] food web'' is a complex interaction between fauna and flora within the soil. These groups include bacteria, fungi, [[protozoa]], [[nematodes]], micro-[[arthropods]], [[insects]], small vertebrates, earthworms, and plants. Larger [[organisms]] are also a part of the system. Each specific element within the food web works together with chemical, biological, and physical forces within the environment to maintain healthy soils and how it interacts with other flora and fauna. [1] It was first described in the academic literature of Dr. Elaine Ingham, a soil biology researcher, and microbiologist. [5]

[[Food webs]] are all the [[food chains]] within a single ecosystem with each food chain being a possible path of nutrients and energy as it is moved throughout the environment. [2]

==Organisms and their Interactions==
Each organism interacts with other species within the soil food web. Within a food web, there are [[trophic levels]] between each interaction ranging from the first tropic level to the fifth trophic level which dictates the roles occupied by that organism in the ecosystem. The first trophic level is primary producers, followed by primary consumers, secondary consumers, tertiary consumers, and apex predators. [7] Below are the different trophic level organisms and interactions present within the soil food web;

*Plants - The first trophic level, a primary producer. Nematodes and fungi feed into the shoots and roots of plants while [[Organic Matter|organic matter]], waste from plants, is created due to the [[decomposition]] of plants.

*Bacteria - The second trophic level, a primary consumer. A part of decomposers and feeds off of organic matter produced by the primary producers, plants.

*Fungi - The second trophic level, a primary consumer. Feeds off of plants and organic matter.

*Nematodes - Three types of nematodes dependent on size. The first nematode is a primary consumer that feeds on the roots of plants. The second nematode is also a primary consumer but feeds on fungi and bacteria. The final nematode and the largest in size is the predator, which consists of the third trophic level, secondary consumers. These nematodes feed on other smaller nematodes and protozoa found within the soil.

*Arthropods - Two types of arthropods are found within the soil; shredders and predators. The shredders are a part of the third trophic level and feed on root-feeding nematodes, fungi, and bacteria. The predator arthropods are a part of the fourth trophic level, tertiary consumers. They feed on predator nematodes, and shredder arthropods.

*Fauna - This category of organisms consists of birds and [[animals]]. They are both at the fifth trophic level, the apex predators of the soil. They both eat predator arthropods. [4]

==Soil Food Web Functions==
[[File:soil organisms.jpg|thumb|800px|right| [https://www.nrcs.usda.gov/Internet/FSE_MEDIA/stelprdb1237707.jpg] Functions of Soil Organisms [4]]]
The organisms within the ecosystem existing in the soil depend on the interactions with each other to maintain survival and growth. In turn, these organisms support nutrient growth as they enhance soil structure, control populations of [[soil organisms]], and decompose organic matter. [4] Below are some examples of soil food web functions present within the soil structure;

*[[Nutrient Cycling]] - The fecal excretion from predators such as protozoa and nematodes from the consumption of bacteria and fungi release nutrients. The plants in the soil then absorb these nutrients, causing the plant to flourish and enhance plant growth. [1]

*[[Bioturbation]] - This is a process in which plant residues mix into soils by biotic activity such as earthworms, [[Pot Worms|pot worms]], [[collembola]], [[mites]], and [[isopods]]. It regulates the flow of water and gas as well as dissolves nutrients within the soil. This process advances decomposition and creates habitats for another microfauna within the ecosystem. [6]

*Decomposition of organic matter - Decomposition within the soil is abundant among soil animals such as earthworms and termites. This decomposition process occurs by dispersing microbes throughout the soil by mincing organic material. These decomposers play a crucial role within the soil food web as it allows for waste management and pollution control within the ecosystem. [1]

*Capture of energy - Photosynthesizers within the soil such as plants, algae, and bacteria capture the energy and use solar energy to fix CO2. [4]

*Control of populations - Above-ground animals such as mice, shrews, birds, and larger nematodes control the population of lower trophic level predators. These larger organisms also improve soil structure by carrying smaller organisms large distances and burrowing. [4]

==Soil Organisms Habitat==
Organisms within the soil are not distributed evenly unlike other ecosystems present in our world. Rather, they live in 'hotspots' where much of the nutrients, and moisture are found regardless of the space available. They most often occur where the organic matter is found and are within a range of a few inches of soil from the surface. Specifically, many organisms are found around roots. This is called the [[rhizosphere]] and consists of narrow areas of soil surrounding the roots and [[root hairs]] of plants found above the surface. These roots are abundant with bacteria that feed on proteins released by the roots and allow the plant to maintain a healthy root system due to nutrient cycling and disease suppression. Another hotspot of soil organism activity is within the litter of soils. Fungi are commonly found here as it is an area abundant with hard-to-decompose carbon. More hotspots consist of [[humus]], on the surface of soil aggregates, and in the spaces between soil aggregates. [4]

Pioneer species

2022-05-03T02:41:38Z

Bdthetfo:

==Definition==

'''Pioneer Species''' are a group of species that are the first to colonize a new habitat created by a previous disturbance. These disturbances could be a fire, flood, or volcanic activity that causes very fine or non-existent [[soil]], high heat, or lack of water.

[[File:moss.jpg|400px|left|thumb| [1] ]]

==Ecological Succession==
Ecological succession is the process that allows pioneer species to become apparent in disturbed habitats. This is a change in structure that occurs within a community or ecosystem and has multiple phases dependent on different patterns of regrowth within an ecosystem. Ecosystems advance until they reach a [[climax community]], where all of the resources are efficiently used and the total mass of vegetation reaches a peak. The concept of ecological succession has two types: [[primary succession]] and [[secondary succession]]. Primary succession is when soils are not yet formed in an area, preventing new vegetative establishment. Over time, small [[organisms]] and erosion break down these rocks into soils allowing for the introduction of pioneer species into the area. More often, pioneer species are brought about through secondary succession, a process that, as long as the soil is not destroyed within a natural disaster-affected ecosystem, can flourish with pioneer species. [2]

[[File:secondary.jpg|right|thumb| https://cdn-acgla.nitrocdn.com/bvIhcJyiWKFqlMsfAAXRLitDZjWdRlLX/assets/static/optimized/rev-5131b73/wp-content/uploads/2017/01/Secondary-Succession-300x117.jpg [2]]]

==Pioneer Flora==
Flora are the first to become pioneer species across all types of natural disaster sites. Due to a lack of nutrients in the soil, most pioneer species have to be hardy plants with adaptations such as long roots and the ability to live in harsh conditions with a lack of water and sunlight. The seeds also have to be able to [[germinate]] easily, allowing species to propagate even after years of dormancy and be able to disperse via wind. This is due to the lack of other forms of dispersal like fauna distribution. The propagule size of the seeds must also be small due to the realization of succession goals and the ability to disperse seeds within small crevices surrounding the habitat. Their lifecycles must also be short as pioneer species cannot stay in one place with little to no nutrients for long. [3]

These species are needed in order to develop and reform ecosystems, allowing for development in a nutrient-poor environment.

Examples of Pioneering plant species:
*'''[[Lichen]]''': A fungus and an alga typically found on rocks and shady places
*'''[[Moss]]''': Non-vascular plants that form dense green clumps in damp and shady areas
*'''Grass''': Small-seeded blades of plant that grow in crevices

==Pioneer Fauna==
While pioneer fauna is harder to find and typically does not appear until the pioneer flora has first established an area, there are still some species that are more so present in the early stages of disaster-struck areas. Some examples of pioneer fauna are soil [[invertebrates]] like worms, ants, snails, and possibly even some toads. These species are important to the soil of the area, as they both help the pioneer flora to flourish but also bring nutrients back into the soil that it was once lacking. Once the introduction of pioneer fauna is present, the area will continue to advance at a rapid pace and more species will start to migrate towards the ecosystem [3].

Plant establishment

2022-03-21T17:52:29Z

Bdthetfo:

== Definitions ==
To define a plant establishment, it must first be known what it is to establish something. Establish can be defined as "to start something that will last for a long time, or to create or set something in a particular way". [1]
Based on that, a plant establishment can be defined as, "the act of a plant taking root within a [[soil]] where it can flourish".

== Plant Establishment ==
When plants first colonize an area, they are limited by a number of factors including competition for resources, environmental conditions, seed availability or a lack of facilitating species. This phase is arguably the most critical part of ecosystem development. A seed has to be dispersed to an area and land on a suitable microsite while also being at a time with favorable conditions for germination and early growth. This is remedied as time goes on because succession will continue, making the abiotic factors and species interactions, like competition, more favorable for colonizing plants. The more plants that become established in an area, the higher the quality of the soil becomes. This leads to an overall higher success rate of plant establishment. When the soil quality raises to a certain point, smaller seeds are able to establish themselves, adding competition to the area, which makes the site even more suitable for other types of plants. The [[diversity]] will create many more [[microsites]] in which plants with contrasting resource requirements can establish themselves and coexist. [2] This increase in biodiversity is beneficial to the overall health of the ecosystem, and the area in general.

Physically harsh environments such as outwash plains, pumice deposits and other fresh volcanic surfaces, can be extremely limiting for plant establishment, but not impossible. In these types of areas, the soils are typically extremely infertile with very poor water holding capacity, the surface is potentially unstable, and is often exposed to wind or lacking in shelter. Any little advantage that a seed can get to survive will give it the chance to establish itself. These advantages include depressions and other concave surfaces, larger stones, rocks and already established plants. The depressions and concave surfaces may increase soil moisture, provide shelter from temperature extremes and winds, or trap seeds. The larger stones, rocks, and established plants can also create favorable conditions by reducing wind and direct solar exposure, thus lowering evaporation rates and moisture loss. [4] These species can be considered [[pioneer species]] within their environment.

== Moss ==
[[File:moss.jpg|frame|Moss hanging over a rock, creating a shady area [7]]]
[[Moss]] is a type of vegetation that is usually one of the first [[organisms]] to colonize an area, although it is typically restricted to moist environments. Mosses are considered bryophytes which are more complex than algae, yet less complex than vascular plants. [8] They have been found to be both a facilitator and a deterrent for plant establishment. Moss could potentially create shade, which can deter plants from growing due to a lack of sunlight getting to the new plants. However, the shading can also help newly establishing plants, as stated above, by limiting direct sunlight which would reduce evaporation rates. The potential increase in moisture would most likely be used by the moss itself, but most mosses are capable of surviving prolonged periods of desiccation, so plants do have a chance to receive that extra moisture, which can be seen as facilitation by the moss. [5&8] In colder environments such as an outwash plain, moss has been seen to create enough cover to protect seeds from heavy frosts, facilitating plant establishment. Mosses have also been found to secrete allelopathic substances which can prove to be a deterrent for plant germination, however, the substances mainly affect herbivores, causing them to stay away from newly established plants. [5&6] Overall, moss can be helpful in the creation of plant establishments by buffering environmental extremes, but are not beneficial to plants once they have taken root. [6]
