Athropods: Arachnids Brief Intro to Arachnids: -Arachnids are a class (Arachnida) of joint-legged invertebrate animals under the Arthropods classification. -Almost all extant arachnids are terrestrial. However‚ some inhabit freshwater environments and‚ with the exception of the pelagic zone‚ marine environments as well. They comprise over 100‚000 named species‚ including spiders‚ scorpions‚ harvestmen‚ ticks‚ mites and Solifugae. (Any water in a sea or lake that is neither close to the bottom

Do you ever wonder how every living organism in the present generation have reached this point? How they are the ones that survived to live in today’s world? Darwin’s Theory of Evolution states that everything with life descended from a common ancestor. It is through natural selection that organisms with the best suited traits for their environment survive through reproduction and they pass down those qualities to the next generation. Predator and prey share the same ecological community and they

Evolution Simulation: Predator-Prey Introduction: Need to add more….. This experiment is an attempt to simulate evolution by means of natural selection. Hoefnagels (2009) Natural Selection is defined as the differential reproduction of organisms based on inherited traits. Hypothesis: Using the first fabric we expect the colors red‚ green‚ and black to have the highest population resulting from predator stimulation which will result in decrease or extinction in other colors in this experiment

snowshoe hare and canadian lynx have cyclical fluctuations in their numbers. There are links between the two creatures and the numbers of the population of each species cycle as over the five year periods they either increase or decrease in numbers and you can spot a pattern between the two sets of figures for each year. They show these fluctuations because different events occur that result in there being a sharp increase or decrease in population numbers for a specific species. At one point factors mean

Predator-Prey Relationships: Coevolution versus Escalation Species on Earth interact in many different ways (Abrams‚ 2000). These interactions have evolved over millions of years to become an incredibly complex web of inter-species relationships and understanding these relationships enables science to model future species interactions (Abrams‚ 2000). From symbiosis to parasitism‚ Earth seems to have every type of relationship imaginable (Dietl and Kelley‚ 2002). One of the most intriguing

These math techniques are primarily used today in information technology to solve problems that present themselves such as those of efficiency. These problems can be solved by using graph theory‚ showing the relationship between

What is biodiversity and what are the impacts do invasive species have on biodiversity? Biodiversity is the variety of animal and plant life in a particular habitat; it also means all of the different natural processes on the earth. There is estimated to be more than 11000 tree species in the amazon rainforest‚ that a huge amount of different species and that’s only for one part of the world. It is important to have biodiversity‚ Biodiversity boost ecosystems productivity. What is productivity?
