Competition- food storing birds and non-food storing passerines are competing for the same food in this environment. However, Food storing passerines birds will survive the competition of "survival for fitness" due to their natural feature of creating "cache" going for a long time without food as compared to non-food storing passerines.
Limited resources- The same birds are competing for the same resources so there is full utilization of available limited resources. Food storing birds will be favorite for this environment as they store more food. This climate will not favor non-food storing birds as they don't store food.
Variation-non-food storing birds will have the best variation in this environment. Food storing birds in this order would vary in terms of food storage as they create more "cache". Non-food storing birds will vary by adapting to the environment with scarcity resources.
Differential survival – the food creating birds of this order will survive longer in this climate as their feature of storing food for a long time and large hippocampus is adventitious.
Heritability- the food creating birds will definitely survive this climate. However, with time the generations of food creating birds will be inherited to offspring as they will still be inherited to their offspring.
Genetic drift – there is the possibility that with time non-food creating birds will drift as resources continue to be limited with time.
Competition- The competition for food is experienced between the Burren wolves and predators. Therefore the Burren vole that has the best avoiding skills will survive. Predators will strive for food to survive in this environment as predators with highest hunting skills will survive. Burren vole adopted bolting features to run away from predators.
Limited Resources- As Predators are competing for the same food the resources will be limited. Burren vole with best hiding techniques will survive. Bolting Burren vole, therefore, survives in this environment due to their hiding tactics as the number of "freezing" Burren vole decreases.
Variation – Burren vole will vary in "bolting and freezing" while predators will vary in "hunting "techniques.
Differential survival – Burren vole with "bolting" technique will survive longer than the "freezing". The bolting over rocks will confuse the predators as it provides the best hiding techniques. On the same time, predators with high timing and hunting skills will survive as they are likely to attract the Burren before disappearing.
Heritability- The "bolting" Burren vole will pass these features onto their offspring's. The future of "freezing" Burren vole will decrease at a higher rate and there will be a high number of "bolting" Burren vole.
Genetic Drift – As the striving for fitness progress there is a possibility that the generation of "freezing" will be drifted out.
Competition- both wild dogs and African painted wolf are competing for the same food. African dog will survive the competition having heightened aversion learning that suits the survival and can adapt to the environment. This shows that both dogs inherit from the same species but adapted from the different environment as they feed on similar foods.
Limited Resources- Both wild dogs and Africa painted wolf are competing for similar resources. There would be limited resources. African dog does not have strong "neophobia" and will survive in any environment. The limited resource has impacted the African wolf to adapt to a version learning of taste as the competition of available resources increases
Variation- wild Africa dogs will vary in "neophobia" while African dog will vary with "heightened aversion learning".
Differential Survival- the African wolf will survive in the environment as probabilities of wild dog species adapting to taste aversion learning being expected.
Heritability- The African dogs will inherit this feature to the offspring and over time there will be a general inheritance of African dogs. The wild wolf will inherit the future of strong "neophobia" due to environmental adaptability but if the food will be limited to 5% then it will adapt to taste aversion learning means.
Genetic Drift – Africa dogs will increase due to their aversion leaning of taste adaptability. However, if the wild dog will not adapt to taste version learning then over time this trait will drift out.
Competition- the competition is between the pythons and the piki monkeys. However, the piki monkey that builds a strong bond will escape the attacks. Pikes with loosely bond will be exposed to attacks.
Limited Resources- Troops of large pythons are competing for the limited resources. Piki money with lifelong social bonds will survive the attacks as piki monkey with loose social bonds will be more attacked.
Variation – Piki monkey vary in social relationships that exist between them.
Differential Survival- piki monkey with the close family relationship will survive longer. The male will protect the family by moving in groups scaring away attacks from the pythons.
Heritability- piki monkeys with strong live long social bonds will inherit this features and continued existence of their breeds is expected. They will increase in number as male protects their territory from attacks,
Genetic Drift – Over the time monkeys with loose bonds will drift out. The genetic adaptation of close family bonds within piki monkey will increase.
