Grasshopper's 3 Forces Of Social Interactions Force

310 Words2 Pages
Grasshopper in a group are subject to attractive three forces based on combined sensory, chemical, and mechanical cues that affect their motion. These forcess represent the grasshopper swarming behavior and they are:
1. Downwind advection force
2. Social interactions force
3. Gravity force
There are N grasshoppers in the swarm group, and the ith grasshopper has position xi. The general grasshopper mathematical model is defined as follows: xi = Si + vg + va (1)
The direction of grasshopper swarm migration is strongly correlated with the direction of the wind and has little macroscopic motion in the transverse direction.
For simplicity, this mathematical model ignore the transverse direction, and hence the grasshopper mathematical model is two-dimensional

The pill bugs were cuddling with each other as a way to preserve the heat and therefore, wouldn’t waist a lot of energy and eventually die. For the 24 C the bugs where moving at a full speed. As it is said that the pill bugs are well adapted to moist temperatures because they need it as a way to breathe and not die from dehydration. Pill bugs tend to come out during the day because of the moist. The results are compatible with the results of the group experiments.

Pill bugs (Rollie Pollie): The Effect of Isopod Behavior on Wet vs Dry Stimuli Abstract: There are two main purposes for this experiment. First, isopods were observed so that their behavior could be recorded. Second, we exposed the isopods to a wet cotton ball and dry cotton ball, to determine which stimuli the pill bugs (or Rollie pollies) preferred over the other.

The two moths share a commonality: the primitive instinct to live. Moths use their wings to fly, to travel, to find food and shelter. However, when a moth’s wings are “a single nightmare clump still wracked with useless, frantic convulsions” (Dillard), the wings

Butterflies, as free as they may seem, were once creatures incapable of flying along their own paths. As caterpillars, their mobility confines them and limits their abilities. Through their development in metamorphosis, caterpillars turn into an independent insect worth marveling over. In the novel In the Time of the Butterflies by Julia Alvarez, the symbol of a butterfly fits Patria Mercedes Mirabal well because her views on the rebellion change suddenly and dramatically, from isolation to involvement. Just like a butterfly, Patria Mercedes Mirabal changes as time and her surroundings require her to.

The Moth set out walking. It could only heave the golden wrinkly clumps where its wings should have been; it could only crawl down the school driveway on its six frail legs" (Dillard 3).

These unique animals are known for being strong and smart. This ants collect grass and bring it back to the colony. An ant carrying a blade of grass is like human carrying a 50 ft pole. Though these ants don't eat grass, they give it to a fungus which eats the grass then produces more fungus, and that fungus is what the ants eat. They are even so smart to build vents at the top of their hills to let the heat from the fungus out.

Diptera is an order of insects commonly referred to as true flies. Diptera stands for two-winged insects (di = two; ptera= wings), because the first pair of wings is primarily used for flying and the second pair is modified to form a small, club-shaped structure called halteres which aids in flight. Also flies have a mobile head, with a pair of large compound eyes, and mouthparts designed for piercing and sucking (mosquitoes, black flies, and robber flies),or for lapping and sucking in other groups. Flies undergo complete metamorphosis; the eggs are laid on the larval food source and the larvae, which lack true limbs, develop in protected environment, often inside their food source. The pupa is a tough capsule from which the adult

Did you know that cheer is almost as dangerous as football, but it’s not considered a sport?”When the activity began in the 19th century it was only for men. But it has evolved over the next hundred years. It is now a female-dominated activity forming the basis for the popular girls and women cheering in short skirts, and waving pom-poms.” (Devoe,2019) So cheerleading should be considered a sport because cheerleading is as dangerous as football, and is considered to be even harder.

M2D1 The type of attraction that the wife had for the Canadian couple was social attraction. I think she was socially attracted to them because they were all teachers and had a lot in common because of their jobs. This being said, I feel that the two couple’s had to have had some kind of physical attraction to each other at first to have begun talking. “Moreover, research suggests that early on in a relationship, we are more likely to expose ourselves to and be influenced by a source we perceive as physically attractive” (Wrench, McCroskey, & Richmond, 2008, pg. 35).
