This ScienceStruck article informs you about the various symbiotic interactions existing in the grassland biome. ScienceStruck Staff. Soil biota, including bacteria, algae, fungi, and soil invertebrates (arthropods Another type of mutualistic relationship, one between plants and. Grasslands are among the most extensive and heavily exploited environments into the soil by plants and microorganisms, contributing to grasslands' may also form symbiotic relationships with grass roots in the Serengeti.

Grasslands have fertile soils, and grasses are the predominant species of vegetation, with areas often fragmented by the conversion of natural spaces to agriculture.

Mutualism in Grasslands by Liz Gonzalez on Prezi

Temperate grasslands generally have low precipitation inches per year and are impacted by both drought and fire conditions.

The fauna of temperate grasslands is unique and the relationships between species include several instances of symbiosis. General Symbiotic Relationships Symbiotic relationships are close relationships between two or more different species, where one species' behavior influences the other species.

There are three main types of symbiotic relationships. The first is mutualism, where both species experience positive benefits from the interaction.

Symbiosis: Mutualism, Commensalism, and Parasitism

The second is commensalism, where one species benefits and the other species experiences no effect. The third is parasitism, where one species benefits and the other species experiences negative effects or harm.

Increased plant fitness may indirectly help plant communities resist colonization by exotic, invasive weeds. Grassland and shrubland plant species in Asteraceae sunflower familyFabaceae legume familyRosaceae rose familyPoaceae grass familyand Solanaceae nightshade family are frequently colonized by mycorrhizae Miller Symbiotic relationships with mycorrhizal fungi are less common or nonexistent among the species in Cactaceae cacti familyBrassicaceae mustard familyand Chenopodiaceae goosefoot family families Miller Biological Soil Crusts Biological soil crusts help stabilize surface soils, retain moisture, enrich the soil with nitrogen and carbon, and provide a favorable microclimate for seed germination.

NPS Biological soil crusts are unique biological communities of fungi, lichens, algae, mosses, bacteria, and cyanobacteria photosynthesizing blue-green algae that live on the soil surface. Biological soil crusts perform a number of vital functions in southwestern grassland and shrub-steppe ecosystems. They stabilize surface soils, retain moisture, enrich the soil with nitrogen and carbon, and provide a favorable microclimate for seed germination.

Rhizines filaments from mosses and lichens, gelatinous sheath material from mobile cyanobacteria, and fungal hyphae bind surface soil particles together, reducing wind and water erosion Belnap et al. Windborne and waterborne dust, seeds, and other organic material are captured and retained in the uneven surface created by intact soil crusts Ford et al.

Well-developed biological soil crusts also play an important role in post-fire revegetation. Species interaction or symbiotic relationships are primarily of three types: Mutualism It is a condition that is beneficial for both the species. The needs for survival of both the organisms are fulfilled. Monarch butterflies feed on the milkweed plant leaves. As the sticky sap from these leaves is also a chemical poison, it protects the larvae from any vertebrate attackers.

The butterflies lay their eggs on milkweed, helping them in pollination in return. Similarly, as grazing animals cannot utilize the cellulose content present in grass on their own, the bacteria living in their stomach help them in digesting it.

Therefore, animals get their nutrition digested and the bacteria get their food too. A Classic Example of Mutualism in Tropical Grasslands or Savannah Mammals are always irritated by little flying bugs sitting on their ears and nose, especially by the ticks sucking their blood. These tiny creatures can even cause a disease and be fatal to them.

So, a kind of cooperation exists between an Oxpecker bird and a Zebra, when the latter allows the former to sit on its back. The oxpecker eats away all the deadly ticks and fleas!

Commensalism It is a kind of relation where either of the two species benefits, leaving the other unaffected. Cattle Egret and Herbivores is one such pair of species showing commensalism.
