Ap biology ecology essay

Birds can learn that caches are halfway between two landmarks. Wetlands are areas covered with sufficient water to support aquatic plants.

Niko Tinbergen found that digger wasps found their nest entrances by using landmarks, or location indicators, in their environment. One of the most powerful ways that environmental conditions can influence behavior is through learning, the modification of behavior based on specific experiences.

Stratification of vegetation provides many different habitats for animals. Most aquatic organisms are restricted to either freshwater or marine environments. Classical ethology presaged an evolutionary approach to behavioral biology.

This process can occur either as primary or secondary succession. An example is the mouse eating the poisonous caterpillar and learning to avoid such caterpillars in the future. In the red-spined stickleback, the male attacks other males that invade his Ap biology ecology essay territory.

Population ecology examines factors that affect population size and composition. One way to predict possible effects of current climate changes is to consider the changes that have occurred in temperate regions since the end of the last Ice Age. A permanently frozen layer of permafrost prevents water infiltration and restricts root growth.

Mule deer are preyed on by mountain lions throughout their range.

Experiments provide evidence for behavioral evolution. Sexual selection can take the form of intersexual selection, in which members of one sex choose mates on the basis of particular characteristics of the other sex—such as courtship songs, or intrasexual selection, which involves competition among members of one sex for mates.

Behavior varies in natural populations. In their studies of vervet monkeys in Amboseli National Park, Kenya, Dorothy Cheny and Richard Seyfarth found that performance of a behavior can improve through learning.

Soil starts to develop gradually as rocks weather and organic matter accumulates from the decomposed remains of the early colonizers. In some cases, the disturbed area is able to return back to its original state. While both kinds of ecological successions have their own unique characteristics and steps, there are some factors both have in common.

Ecological research ranges from the adaptations of individual organisms to the dynamics of the biosphere.

When neither photosynthesis or respiration is taking place, the carbon dioxide from the air combines with water to produce bicarbonate, a source for aquatic producers like algae. As humans continue to use fossil fuels daily, the amount of carbon dioxide in the air increases.

Courtship behaviors of stalk-eyed flies are fascinating. The first forms of life are initially autotrophic and heterotrophic prokaryotes. Some nonmuscular activities are also behaviors, as when an animal secretes a pheromone to attract a member of the opposite sex. The tendency to respond is innate in birds.

Coral reefs are home to a very diverse assortment Ap biology ecology essay vertebrates and invertebrates. The stimulus for the attack is the red underside of the intruder. The other type of ecological succession is called secondary succession.

Community ecology examines the interactions between species and considers how factors such as predation, competition, disease, and disturbance affect community structure and organization. It also increases water loss by increasing the rate of evaporative cooling in animals and transpiration in plants.

Once these mosses establish themselves, soil starts to gradually develop as rocks weather and organic matter accumulates from decomposed remains of early colonizers. Frequency of the three types of males varies from year to year.

The study of cognition connects behavior with nervous system function. The bicarbonate is a source of energy for aquatic producers such as algae and other aquatic vegetation.

When aquatic organisms respire, the carbon dioxide released combines with water to form bicarbonate. Headwaters are cold, clear, turbulent, and swift.

Much of the social interaction between animals involves transmitting information through specialized behaviors called signals. On similar terms to the formation of bicarbonate, when aquatic organisms respire, the carbon dioxide released from them in turn reacts with water to form bicarbonate.

In species where the mates remain together for a longer period, the relationship may be monogamous one male mating with one female or polygamous one individual mating with several partners.

They are then followed by mosses grown from windblown spores. In species that provide parental care, parent-offspring bonding is a critical time in the life cycle.Advanced Placement Biology - The official AP Biology site at the College Board.
