Level of Aggression in House Crickets (Acheta domesticus) With Different Resources Available
Abstract: The house cricket, Acheta domesticus, was used to test whether food and potential mates drive aggressive behavior. Male crickets were randomly selected in pairs and place into a cage to observe aggressive behaviors in the presence of no food, food, and female. The cage provided a confine area for the crickets to fight one another while the variables of food and female were used in attempts of increasing aggressive interactions between the male crickets. There was no significance found through this experiment due to a lack of data. It was discovered that the experiment would have to be done at a larger scale to be able to see any significance in the two variables.
Intro: Charles Darwin’s natural selection comes to mind when viewing the aggressive behaviors in crickets. This interaction comes into play specifically when competition for resources, such as foods and females, are scarce. Thus, only the organism most fit in the environment would be allowed to survive and pass on its genes. Pioneers of animal behavior, pave the way to understanding the why animals act the way they act (von Frisch, 1967; Lorenz, 1952; and Tinbergen 1951). With further integration between different biological organizations, we see the rise of new possible research, especially in crickets (Wong & Hoffman, 2010). The house crickets, Acheta domesticus, would normally display little to no aggression between males because of their natural behavior to live in groups. But when isolated for a length of time, ag...

Variation in selection pressures on the goldenrod gall fly and the competitive interactions of its natural enemies
In life, actions and events that occur can sometimes have a greater meaning than originally thought. This is especially apparent in The Secret Life Of Bees, as Sue Monk Kidd symbolically uses objects like bees, hives, honey, and other beekeeping means to present new ideas about gender roles and social/community structures. This is done in Lily’s training to become a beekeeper, through August explaining how the hive operates with a queen, and through the experience Lily endures when the bees congregate around her.
All around the globe, people have attempted to find an organic, genetic basis for aggressive behavior. Several hormones and neurotransmitters, such as testosterone and seretonin, have been implicated in the "aggression quest", as well as specific localities of the human brain. My paper will serve to suggest that although many findings have shown impressive results regarding possible biological causes of violent behavior, we still do not have sufficient means to understand the neuroanatomical or biochemical basis of aggression.
Throughout The Secret Life of Bees , there is no shortage of symbolism, coming directly from its namesake, bees. Each connection draws upon the deep and rich meaning behind this wonderful composed text. The bees, however, never are a scapegoat. Similar to Harper Lee’s To Kill a Mockingbird character Atticus, they never allow for shortcuts or disillusion with reality. They force you to see the world as it is, and to accept it, and send love to it, for it is all you can, when you are as insignificant as a
Some individuals have developed different traits to help them in the process of intra-sexual competition. The organisms with more distinctive traits have greater reproductive success. More genes of those traits are then ‘selected’ and are passed onto the offspring of the organisms. Throughout time variability in these traits becomes

confusum have divergent behavior patterns. During an experiment between competition over limiting food resources (flour), T. casteum exhibited more aggression by eating their own larvae (Ho and Dawson 1966). Another experiment had similar results; after ten hours, 88% of T. confusum males and 33% females remained, and 2% of T. castaneum adults survived (Ghant 1966). The low population of T. castaneum is due to their cannibalistic nature. The purpose of conducting this experiment with the variable of different species is to determine whether or not there is more intraspecific competition in T. castaneum. In order to accomplish this, both populations of the Tribolium species will be measured over
These populations are often limited by water or food supply and have large territories.[25] Female-female aggression in the noncommensal house mouse populations is much higher, reaching a level generally attributed to free-ranging species. Male aggression is also higher in noncommensal populations. In commensal populations, males come into contact with other males quite frequently due to high population densities and aggression must be mediated or the risk of injury becomes too great.[24]

In order to understand the present lifestyles relating to different approaches and tactics applied by humans in mate choice preferences, there is the need to refer to Darwin (1859, 1871) evolutionary perspectives. Darwin (1871) sexual selection is the driving force for males and females reproductive quest for their genes survival. These driving forces have been classified into two categories as intra-sexual and intersexual mate selection.Intersexual selection is male sexual selection process whereby males compete with other males and the females choose the strongest as their ideal partner. Intra-sexual selection occurs when the male species fight among themselves and the strongest gain access to females for
The objective of the Capture-Recapture Cricket Investigation was to find out how much crickets there were. Each group would get a piece of paper towel and place the paper towel in their group’s box. Then, they would count how many crickets have a White-Out mark on their back. After that, they mark the remaining crickets in their box who don’t have a White-Out mark. The indication of the importance of the work is that scientists could use the

The ability to control aggression largely defines individual’s and societies’ success, on and off the field. Aggression is a highly controversial attitude that is commonly associated with physical violence. The act of aggression is used to assert power and control over others. Whilst viewed as a negative personal characteristic in most societies, aggression is a primal instinct and a trait that often transpires to success in a sporting environment. In sport it is essential that an athlete can hone and control their inner aggression in order to dominate the opposition. Controlled aggression is the mark of a successful player and a team’s ability to win.
