Predator

SOME DINOSAURS WERE LIKELY TO BE WARM BLOODED Dinosaurs belong to class Reptilia and so for many years scientists thought that they were cold blooded, with slow metabolisms and dominated the planet for about 135 million years. However, birds evolved from small carnivorous dinosaurs of the Late Jurassic, with fast metabolic rates, raising the question of whether or not their extinct dinosaur relatives were also warm-blooded. Whether the extinct dinosaurs were ectothermic or endothermic or…

to get the highest thrip control. Colonization and predation of thrips What did they want to know? Knowing that western flower thrips are one of the leading problems regarding sweet pepper crops the researchers wanted to see if they could use predators successfully as a way to treat thrips since the current use of pesticide…

Predator and prey play an important role in our ecosystem. They each have roles that directly or indirectly affect one another. Species of the same kind which live and interact of the same region is called a population. For example, the wolf and moose each make up the population of their species. The environment in which includes all living and nonliving things interact is the ecosystem. On Isle Royale, scientist have studied the interaction between the wolves and moose and how they each…

The Merriam-Webster dictionary explains evolution as a theory of changes that occur because constant change that excel naturally over a long period of time. (Merriam-Webster) This means that over a long period of time there were changes made from all the species and as time progressed we all started to break up into different categories and then different branches of those categories. It is said that we, as humans, share the same category as the primates. Though, over time we started to evolve…

animal in a sense. They are in extreme breeding state with all of their senses honed in on finding a doe in heat. The white-tailed deer lives in wooded areas. In some areas, deer overpopulation is a problem. Gray wolves and mountain lions used to be predators of the white-tailed deer and helped keep their…

and when an animal does not die quickly it is a tragedy. Additional training would certainly be welcome, as it would only improve a hunter’s ability to carry out ethical hunting. In one way hunting is more humane than natural predation. When large predators, such as wolves, capture prey the death may not be quick. Prey species are often chased before capture and suffer greatly before death. (Also there is already an extremely powerful, though selfish, motive for insuring a quick and precise…

The bottlenose dolphin lives in the Pacific Ocean. They live in places like Japan, southern California, Australia, and Chile. They can also be found in the Atlantic and southwestern Indian Ocean. Bottlenose dolphin are not found in cold waters. A bottlenose dolphin has a wide variety of food that it eats including fish, squid and crustaceans.Bottlenose dolphins are around eight to nine feet long,and their skin is gray.Unlike most mammals the bottle nose dolphins don't have hair. They use their…

hot springs capable of killing a significant proportion of the resident microbial populations. They play an important role as predators of hot spring microbial communities and influence carbon and nutrient cycling in these extreme environments. In extreme thermal environments above the upper temperature limit for eukaryotic life, phages play an important role as predators of prokaryotes in hot spring microbial communities and they also influence carbon and nutrient…

the colossal squid in the 20th century. The only items of evidence scientists previously had were beaks, tentacles, and other parts of fallen colossal squids that were slowly digesting in the stomachs of sperm whales (one of the colossal squids predators) that had been beached and had died or previously captured and killed whales. This all changed in 2-22-2007. The scientists finally had a whole body of a female colossal squid body for evidence and…

term "landscape of fear." A landscape of fear is a map of the effects the predators have on their prey. The effects of long-term fear among the prey population just because of the presence of the prey is graphed into a map of sorts. Some people don't believe animals can experience long term fear, but a researcher named John Laundre is changing this notion. We know they experience short-term fear during a chase or when a predator is about to pounce on them. We also know fear can cause a…
