Research another that has less of the same

Research south africa, is showing the effects of immigration on a few small packs of Dwarf Mongooses. Researchers have studied these small creature for months now. Long enough to learn that these little guys are not open to welcoming new members into a pack,and that even though the immigrants are unwanted by residents, in the end everyone benefits. For the Dwarf Mongooses, increase in number, is beneficial. These animals live in up to a pack of 10 and earn a new member a year, however it is rather difficult for these new immigrants to fit into the social spectrum of a new pack. Often, they are looked down upon. A lot of the time residents, prefer not to have a new member on guard duty, because these animals are not very trusting, and often wont respond to a warning call put out whether the new member has yet to learn a personalized call the pack has, or the pack just doesn’t trust the newbie.

It is difficult. Dwarf Mongoose packs follow a social hierarchy, and always start at the top with an Alpha. This is your top female and top male. They are in position of breeding, while others in the social spectrum work in group activities such as watching young, and caring for members, or guarding the pack. Due to this social spectrum, it leaves some individuals the opportunity in competition.

A lot of the time individuals will leave one group for another that has less of the same gender, leaving the individual with less mating competition. But a explained above the transition is not always welcoming. However in the end it benefits all, the individual is eventually warmed up to, and the more merrier for these little guys cases. Everyone benefits from more protection and that’s exactly what happens when a pack grows.

Often however it does take up to five months for a member to feel fully apart of his or her pack. I chose this article for relation to our ecology unit that we have just covered, as a wide aspect of it was what affects a population’s size, and in cases how it may benefit. One of the many determinants for population change is immigration. In this case, it sounds like there is an addition to the packs population yearly, allowing for growth in their population numbers.

Something else that we covered were competitive factors in a population. Dwarf Mongooses experience intraspecific competition. This is because there are multiple individuals of one species competing for something they have in common, majority of the time this is mates. These little animals often rely on density dependant situations. For example their competition relies on density, as does their social spectrum.

They can’t have the positions they have without a fair number of individuals in the population.I liked using this article for relation to the ecology unit it because it was very straight to the point about these creatures and how studies have shown how they benefit one another and work off of one another, in capability of protecting themselves. It was easy to understand this article and relate it back because it was very clear to what I had learned in the ecology unit, and I was able to relate different factors that could occur in this specific population, with full knowledge and understanding of how they live.
