Symbiotic relationship humans and domesticated animals

symbiotic relationship humans and domesticated animals

Jul 3, It is highly plausible that mice, like dogs, followed humans as fully domesticated animals. Dogs, as sanitation agents, had a relationship with. Dogs were the first domestic animal with whom we developed a close association. "The human-dog relationship amounts to a very long lasting symbiosis. Humans live in symbioses of various intensities with a number of domesticated animals and plants. To varying degrees, these cultural symbioses are mutualistic, .

While the entire ecosystem is interdependent to a degree, thousands of fascinating examples of symbiosis exist between dissimilar creatures. Symbiosis is the living together in more or less intimate association or close union of two dissimilar organisms as in parasitism or commensalism ; especially mutualism. Parasitism is where one of those organisms gains all the benefit to the detriment of the other species. For example, mistletoe is a parasite that drains nutrients from its host and gives nothing back.

Parasitism is not a part of this discussion. Commensalism is where one organism uses another for its benefit without harming the other. Mutualism is the mutually beneficial association between different kinds of organisms Mutual symbiotic relationships between dissimilar species It is unbelievingly amazing how many instances of mutual symbiosis exist across the global ecosystem. Here are just a few examples: The ambrosia fungus uses beetles for transportation. The relationship is such that the beetles have developed saddle-like pouches in which they carry the fungus, and they can feed the fungi as they travel from dead tree to dead tree.

In fact, this Yahoo article describes five kinds of fungi that 'farm' animals. The acacia tree provides a home and food for the ants, which in turn protect the acacia tree and the ground space around it against both insects and plant seeds. Acacia trees without ants do not thrive as well.

Symbiotic Relationships. Fascinating examples of symbiosis

Insects chew on the leaves, and taller trees grow up and dwarf the moderately sized acacia tree. Wikipedia Herbivores and bacteria. Herbivores including rabbits and cows cannot survive without bacteria in their guts to break down indigestible plant materials into nutrients a cow can use.

It then digests the nutrients and some of the bacteria. How is this symbiotic? Because the food eaten by the herbivore becomes food for the bacteria.

The bacteria multiply to the degree that bacterial population overages become food for the herbivore. See also Carnivore Digestive System. These two species literally combine to form lichens of various shapes and colors.

The relationship is described as obligate in that there is no lichen without the participation of both species. It is symbiotic in that a "soup" of nutrients contributed to by both species provides nourishment for both. Because of the combined traits of both species, lichens thrive in inhospitable climates, from dry deserts to frozen tundras.

Remora fish have suction cups on their heads with which they attach themselves to sharks, whales and other very large fish. Dogs and humans have been linked since early human history. Through domestication and selective breeding for various needs, we now have dogs that help us with specific chores, depending on the breed.

Anyone who owns a dog is familiar with the "gaze"—that hypnotic, imploring stare that demands reciprocation.

It can seem to hold a world of mystery and longing, or just pure bafflement at what makes humans tick. It turns out that the look of mutual recognition between human and dog reflects thousands of years of evolution, a bond programmed into our very body chemistry.

Researcher explores close prehistoric relationship between humans and dogs

Last spring a research team in Japan discovered that both species release a hormone called oxytocin when they look into each other's eyes—the same hormone released when a human mother beholds her baby. What's more, the Japanese study showed that higher levels of oxytocin were released during that gaze than during petting or talking. It seems that for dogs, at least where humans are concerned, eyes really are windows to the soul. But where does that unique symbiosis begin, one that has long involved even the sharing of parasites and certain diseases?

According to Losey, the biochemical bonding impulse is only one part of the story. His own research is focused on teasing out the cultural forces over time that have made dogs and humans such a good fit. One of Losey's projects involves the excavation of dog remains between 5, and 8, years old at Lake Baikal, Siberia, the deepest freshwater lake in the world. What's striking about the find is it reveals dogs were buried alongside humans in cemeteries, pointing not only to some of the earliest evidence of dog domestication but also suggesting dogs were held in the same high esteem as humans.

Dogs seem to have a very special place in human communities in the past.
