Impact Of Commensalism Of Egret And Buffalo - Plasma Membrane

Cape buffalo and cattle egret by Regina Hart, Flickr. That egret is on the cattle. This would be another example of a commensal relationship. Commensalism is a relationship between two species where one species derives a benefit from The Cattle Egret (Bubulcus ibis) forages in pastures and fields. Egrets remove parasitic ticks from the cows and those ticks feed on What makes the relationship between a buffalo and a cowbird symbiotic?.

Cattle egrets established themselves permanently in the Americas in the s, eventually expanding northward and establishing breeding populations in Florida in the s. Previously, these birds were native to Spain, Portugal, and subtropical Africa and Asia. However, they were able to cross the Atlantic Ocean via flight and establish themselves in the Americas.

As you might guess from their name, cattle egrets tend to associate with livestock. However, this behavior is not specialized and can be seen with many species of grazing mammals, both wild and domestic. As more areas of the world were farmed or cleared for livestock, cattle egrets found more places in which they could thrive. The nature of their relationship with grazing animals is reflected in the cattle egret diet. The majority of its heron and egret relatives rely on aquatic food sources usually small freshwater fish, but occasionally also in tidal areas like the snowy egret in my first story linked above.

However, cattle egrets instead tend to rely on a diet of terrestrial insects and other arthropods, like the centipede in the picture below. There is still some debate as to what type of symbiotic relationship exists between cattle and cattle egrets.

Flocking Together

The movements of grazing cattle can stir up insect prey. This makes foraging easier on the egret, with no effect on the cattle. This would be another example of a commensal relationship.

However, there is some evidence of mutualism as well. Leaves and branches falling from trees often damage smaller plants beneath them.

The trees drop their old structures regardless of whether or not they damage other plants. Predation and competition have particularly important influences on population dynamics. For that reason, we will illustrate several examples of these interactions later in this chapter.

Cattle Egrets with Cattles

All five types of interactions, combined with the effects of the physical environment, determine the range of environmental conditions under which a species can persist. If there were no competitors, predators, or pathogens in its environment, a species would be able to persist under a broader array of physical conditions than it can in the presence of other species that negatively affect it.

On the other hand, the presence of beneficial species may increase the range of physical conditions in which a species can persist. With this background information on population structure and dynamics and interactions among populations, we can now turn to the questions that we posed at the beginning of this chapter. We will begin with abundance and rarity.
