Ants & Mistletoe - A Lesson To Be Learned - PEO Industry Publication
A symbiotic relationship in which both species benefit. Mistletoe grows on oak trees, obtaining support and food Ants will 'farm' aphids, keeping them safe. Symbiotic relationship where both species benefit Ants and Aphids Mistletoe is a parasitic plant that grows on trees, particularly hardwood trees like oak and. Let's take a closer look at these different types of symbiotic relationships. on wasps and aphids to determine the type of symbiotic relationship they have. . Which type of symbiosis exists between the ants and the caterpillars? MISTLETOE: symbiotic relationship between mistletoe and the tree to which it is attached.
Mealybugs are scale insects, considered as pests since they feed on plant juices and can induce leaf drop when they occur in large numbers. They become very serious pests in the presence of some ants, as these ants protect them from predators - again, a display of mutualism. Ant tending to a Mealybug Ants and a Mealybug Treehoppers belong to the family Membracidae, a group of insects related to Cicadas and the Leafhoppers.
Some treehoppers have also developed mutualistic relationships with Wasps. Mistletoe, strangler figs, leeches, fleas fall into this category. Insects like fleas are external parasites, they are wingless and have mouthparts adapted for piercing skin of mammals and birds to suck blood.
Leeches are also blood suckers, they feed on blood from vertebrate and invertebrate animals. Some members of the Mistletoe family are partial parasites.
When birds like Flowerpeckers feed on the fruit of this plant, a sticky substance present in the fruits ensures that the seeds get stuck to their body. To get rid of these seeds, the birds rub their body against a tree, thus enabling seed dispersion - the roots penetrate the branch of the tree and the plant is born.
The plant has green leaves and can photosynthesize, but absorbs nutrients from the host tree instead. Although the Mistletoe is a partial parasite, it is beneficial to the ecosystem, with a wide variety of species depending on the fruits. The plant is also a larval host for the very pretty butterfly, Common Jezebel. Mostly found in dense, tropical forests, these plants begin life as epiphytes. Birds and other arboreal animals act as seed dispersers for these Ficus plants and they grow on top of other trees, by germinating in crevices on branches.
The seedlings then begin their journey downwards, looking for necessary nutrients and simultaneously grow upwards into the sky, in the quest for sunlight.
Symbiosis -- Defensive Examples
In the process, the original host tree is enveloped and often dies. As they grow, the fractals these roots and branches assume look eerily beautiful. Strangler Fig from Bhadra A Symbiotic relationship, on the other hand, takes place between two species where they completely depend on each other for survival.
Symbiotic relationships can be broadly classified into Ectosymbiosis - where one organism lives on another mistletoe, lice, cleaner fish and Endosymbiosis - where one partner lives inside the other zooxanthelles in corals, lactobacilli in humans Lichen, for example, is a composite organism which is formed as a result of a symbiotic relationship between fungi mycobiont and a photosynthetic partner, usually green algae phycobiont.
Algae can photosynthesize by virtue of being a plant. Carbohydrates are produced during photosynthesis, which in turn serve as food for the fungi.
Lichen Lichens rock flower are some of the oldest living organisms on Earth and can survive in varied climates and altitudes. They grow on any undisturbed surface that receives ample light - leaves, branches, bare rocks, walls and exposed soil surfaces. Many lichens are vulnerable to environmental disturbances and their growth is inhibited in such cases. So, they can be observed to assess air pollution.
They are used to prepare dyes, masalas and some medicines too.
Cattle Egrets following a herd of grazing cattle is a common sight in most suburban parks and villages. In forests, we see these Egrets around herds of Elephants, Deer and Gaur.
My Pensieve: Quid pro quo
This type of a relationship is called Commensalism. The word originates from the term 'Commensal' which means 'sharing of food'. Here, one organism benefits but the other doesn't - and it is caused no harm either.
This residue is called honeydew and many other insects, including ants, lap it up. To Ants, Aphids Are Livestock When an aphid-hunting ant comes upon a herd of his quarry, he returns to the nest, leaving a trail of "recruitment" pheromones for worker ants to follow to the source. From then on, the aphids are effectively enslaved by the ants. First, they're drugged with a tranquilizing chemical excreted from the ants' feet, slowing down their speed of movement by about a third.
To make doubly sure the aphids don't get any ideas about taking off, ants may also bite off their wings or secrete chemicals that impair wing development. To "milk" the aphids, ants massage their abdomens with their antennae, stimulating the release of honeydew.
And, if the ants want more dietary protein, they eat the aphids. Aphid Husbandry Ants control the reproductive capacities of aphids to boost numbers of the most useful while phasing out the least productive, mainly by eating them. As a study involving yellow meadow ants in northern Europe showed, they do this by exploiting the female aphid's ability to clone herself.
The ant colonies studied were inside a 4. Even in mounds where more than one species of aphid was being farmed, 95 percent of all chambers contained aphids produced from a single clone.
Ants & Mistletoe – A Lesson To Be Learned
Though we can't know how aphids feel about their arrangement with ants, experts think that the bugs willingly trade their freedom for the protection ants offer from parasites and predators such as ladybugs.
When ants dine on baby aphids and adults who have outlived their usefulness, it's a form of population control, Ivens suggests. The Encyclopedia of Entomology notes that aphids not only don't flee from ants but actually compete for their attention.
