Catfights mainly happen when two cats are fighting for territory. Mercury poisoning happens when mercury leaks into the water and either the Panther directly drinks it, or an animal that they eat drinks the poisoned water. Kitten survival rate is not good either because many are affected by heart conditions from inbreeding. Not many things are being done to stop the Panthers from becoming extinct, but something’s are. Texas Pumas were released to breed with the Panthers.
Is it intelligence that determines the animal’s self-worth and right to live, or is it that animals may possess the same if not identical Neuroanatomy of humans? Suzuki’s primary question examines if the rational behind animal testing is that these animals are dissimilar to human beings; therefore, pain can be inflicted upon these animals without guilt. Suzuki purposes, whether or not the animals need be so close to the human species for the results to be meaningful; Suzuki furthers this inquiry, through his demonstration of logos and ethos. When Suzuki explains the research he has conducted on fruit flies as an alternative to the more commonly used mammals;
Outline and evaluate evolutionary explanations of human aggression (infidelity and jealousy) [8+16 marks] The evolutionary theory states that a human’s main aims are to survive long enough to pass on their genes, and to ensure that those genes live on in their children. If the desire to achieve these goals is not met, or is threatened; humans can become aggressive. Evolutionary explanations can explain aggression in many ways, including infidelity and jealousy. In both males and females infidelity, whether it is real or imagined, causes jealousy and therefore aggression. The jealousy is seen by evolutionary psychologists as an adaptive response and it is therefore useful.
Provide evidence of flexible predatory behaviour and discuss why it should be more so than their prey Over evolutionary time, natural selection has shaped the morphology and behaviour of animals (Wilcox & Jackson, 1998). Therefore, many animals have evolved to be flexible predators, meaning they flexibly alter their behaviour in the face of environmental change, to ensure the successful predation of many prey species (Shettleworth, 2010). Not only this, but these predatory behaviours can be complex and illustrate an astonishing level of cognition (Jackson & Pollard, 1996). This essay provides evidence of the complex, flexible predatory behaviours of Portia, a genus of jumping spider (Salticid) (Jackson & Pollard, 1996). Distinctive from other spider species, Salticids have evolved to acquire acute vision, which is thought to have mediated the development of its diverse predatory behaviours (Jackson & Pollard, 1996).
People began to believe that hunters were only killing to "stuff a trophy" or "get a wall hanger" (Taking aim). The Sampson Law Some people think that those who poach have their own rights because the game is on their property or they are in need. In some cases this is true, but only to a certain extent. They state that if the person who owns the property stocks the lake or creek, or has problems with excessive game animals on his or her property, then this will fall into play. Even then they have to apply for special tags to take the
Aggression in Sport Aggression can be defined as ‘intent to harm outside the laws of the game’ and revolves around behavioural misconduct. This can have a negative or positive effect on a performer depending on the individual, but when the aggression is considered to be channelled for a positive purpose it becomes assertion. However the distinction between whether conduct is aggressive or assertive can be difficult to distinguish in some cases. The causes of aggression can be divided into nature or nurture. Nature is suggested in the instinct theory where aggression is a characteristic shared by all humans as an innate biological drive which is expressed through sport.
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.
How can we prioritise species for conservation? Species becoming extinct: Species are facing various problems key to their survival such as destruction of animal habitats, damage to the natural environment of living things, for example trees are cut down to build homes, , Oil spills, acid rain and water pollution also add to the destruction of habitats. Moreover another cause for extinction is when animals are over-hunted for their meat, fur and other valuable parts. Another cause could be ‘when animals or plants arrive into a new habitat from a foreign place they sometimes introduce diseases that the native species can't fight. These "exotic" species can also prey on the native species’.
During blood feeding, the damage caused to the host blood vessels usually results in vasoconstriction that may increase insect feeding time due to restricted blood flow to their mouth parts. Blood-sucking insect saliva usually contains components promoting vasodilation. Vasodilators such as, a peptide tachykinin has been characterized in Aedes aegypti that facilitate efficient blood feeding. Tachykinins also act as pharmacological
By using a model system is appropriate as one can predict what will happen in a short period of time. Therefore it is hypothesised that the predator finds certain colour of prey more easily in those environments that they do not blend in. In this exploration a simulated model of natural selection of an organism in different environments was used to show the effect of predation on natural selection. Procedure The researcher was provided with a samp of five different colours and two multi-coloured cloth. The samp was to represent individuals of the insect species, the cloth with red, orange, white colour was to represent the environment one and the one with a green, blue and white colour was to represent environment two and
