Although their venom isn’t not lethal to humans it is used to subdue and kill the prey, and they are also known to strangle their prey to death like the Boa Constrictor snakes. When this vicious snake feels threatened its first reaction is to lunge at the threatening object and attempt to bite. This snake is an above average breeder producing 4 to 12 eggs approximately twice a year. This reptile was introduced after World War II when the snake was accidently transported from the South Pacific to Guam allowing for the snake to introduce to other locations such as Florida unknowingly (Rodda, 1992). Since there are no natural predators present in
Leaving most of the body left to mold and beetles, but even after a couple months, when the flesh is almost nothing, forensic entomologists can interrogate the remaining maggots by extracting their juices, because most of the toxins linger in the fly larvae. Therefore investigators can detect the presence of any drugs, poisons, or other chemicals that may have entered the body. Additionally the victim’s race may be able to be determined depending on the amounts of melanin skin pigment in the soil. (decomposition, enotes) There are many factors that can cause variations in the outcome, but for the most part the decomposition of the bodies is based on a specific formula. After the bodies are finished decomposing in the body farm the skeletons are taken and are steam-cleaned where they are put in storage for the use of science once more.
One thought that Dillard spends a lot of time describing in her writing is the image of the dead insect corpses left from the spider in her bathroom. The corpses seemed so insignificant and unneeded, especially because even the spider saw no value in them (it only wanted what could keep it alive). These corpses seem to represent what a life would be like to die without accomplishment. They are like forgotten souls who failed to leave a mark on the world. "Yet under the web are sixteen or so corpses she has tossed to the floor," is a significant line because although they aren't recognized as anything greater than a dead bug, they served a purpose to keep another life (the spider) alive.
Mealworms would be considered prey rather than a predator. They are consumed by various animals such as a variety of birds, spiders, other beetles, rodents, and lizards. Some people from other countries will also consume these creatures (http://www.enchantedlearning.com/subjects/insects/beetles/mealworm/mealwormlifecycle.shtml). Purpose: This experiment is done to see which foods and liquids a mealworm likes. We also see what they are like, how they move around, and how fast some move compared to others.
Other researchers think some people were trying to breed Snakeheads as they bring a large amount of money in some areas. (Frankenfish.com). The Northern Snakehead is a major predator, as it has no enemies. It has the ability to wipe out populations of native fish. “Frankenfish” entire diet mostly contains other fish, as well as plants and insects.
Bio 100 Homework due 11/05/12 Name : Nicholas Oliveira Go to the website on cheetah conservation www.Cheetah.org and read the following sections under the tabs About Cheetahs: Intro, Genetic Diversity, & Race for Survival 1. Why are cheetahs endangered? Our attitudes and misconceptions about these species have led to their endangerment because many people deal with their fear by eliminating predators. 2. What are the 5 most common causes of extinction?
He found that when the SCN was leisoned in a sample of chipmunks they were awake when they should be asleep and vice versa. After 80 days, significantly more of the leisoned chipmunks had been killed by weasels. This demonstrated that circadian rhythms may serve an adaptive function to keep the animals still and quiet at dangerous times when they could be attacked by predators. This study had high internal validity and led to evidence which suggested a causal relationship however, it is arguable that this study was unethical as it could have been predicted that many of the animals would die. It should be noted that the process may be far more complex in humans and thus caution should be exercised in generalising these results to
Fire Ants Invasive Species according to Delach 2011, are “plants, animals or other organisms that are introduced to a given area outside of their original range and cause harm in their new home.” Since they were brought into this new environment, they have no natural enemies to slow down and limit their reproduction, causing the species to spread uncontrollably. According to Delach 2011, Invasive Species are recognized as one of the leading threats to biodiversity and impose enormous cost to agriculture, forestry, fisheries and other human enterprises as well as human health. The Fire Ant is an invasive species that south America accidently introduced to Alabama in 1929 via a cargo ship that was carrying used soil as ballast (FireAnt.net 2005). According to University of Arkansas division of agriculture 2006, “red fire ants can have a positive and a negative impact on the environment and the life in it.” Of course, in the public’s opinion, fire ants are a big pain in the butt and “can only be considered negative” (University of Arkansas division of agriculture, 2006). Environmentally, a positive impact is “as generalist feeders, they can have more than one food source and other insects are their prey (University of Arkansas division of agriculture, 2006).
Ranked secondary to that of the appearance of the insect, during the initial encounter, caused a surprise feeling that involuntarily induced Morgan’s fight-or-flight response. During his vulnerability, he grabbed his golf club, swung and killed the insect. His primitive instinct had completely taken over his rational of his thoughts and actions. This fight-or-flight and kill or be killed instinct is what contributed to the successful venture through evolution. While in Lieberman’s office, it was shown that other insects of the same species were found murdered eight other times, in completely unrelated situations.
Insects are always tiny and have many huge predators. In order to survive, they have furnished with various kinds of self-protection mechanisms through millions of years’ evolution. Camouflage is the most distinguished one among them. Camouflage of insects, as a tactic of defense, can be defined that “Adult insects resemble a whole host of objects and backgrounds, from leaves to bird droppings” (Insects [PC], 2007). Insects which use camouflage look like things in its environment.
