When to Transfer Activity

Pressure, or decompression, enables the mantle rock to melt and form magma. Decompression melting often occurs at divergent boundaries, where tectonic plates separate. The rifting movement causes the buoyant magma below to rise and fill the space of lower pressure. The rock then cools into new crust. Decompression melting also occurs at mantle plumes, columns of hot rock that rise from Earth's high-pressure core to its lower-pressure crust. When located beneath the ocean, these plumes, also known as hot spots, push magma onto the seafloor. These volcanic mounds can grow into volcanic islands over millions of years of activity. Transfer of Heat Magma can also be created when hot, liquid rock intrudes into Earth's cold crust. As the liquid rock solidifies, it loses its heat to the surrounding crust. Much like hot fudge being poured over cold ice cream, this transfer of heat is able to melt the surrounding rock (the "ice cream") into magma. Transfer of heat often happens at convergent boundaries, where tectonic plates are crashing together. As the denser tectonic plate subducts, or sinks below, or the less-dense tectonic plate, hot rock from below can intrude into the cooler plate above. This process transfers heat and creates magma. Over millions of years, the magma in this subduction zone can create a series of active volcanoes known as a volcanic arc. Flux Melting Flux melting occurs when water or carbon dioxide are added to rock. These compounds cause the rock to melt at lower temperatures. This creates magma in places where it originally maintained a solid structure. Much like heat transfer, flux melting also occurs around subduction zones. In this case, water overlying the

Escape from Unsuitable Conditions Some species can survive unfavorable environmental conditions by escaping from them temporarily. For example, desert animals usually hide underground or in the shade during the hottest part of the day. Many desert species are active at night, when temper- atures are much lower. A longer-term strategy is to enter a state of reduced activity, called dormancy, during periods of unfavorable conditions, such as winter or drought. Another strategy is to move to a more favorable habitat, called migration. An example of migration is the seasonal movements of birds, which spend spring and summer in cooler climates and migrate to warmer climates in the fall. THE NICHE Species do not use or occupy all parts of their habitat at once. The specific role, or way of life, of a species within its environment is its niche (NICH). The niche includes the range of conditions that the species can tolerate, the resources it uses, the methods by which it obtains resources, the number of offspring it has, its time of reproduction, and all other interactions with its environment. Parts of a lion’s niche are shown in Figure 18-6. Generalists are species with broad niches; they can tolerate a range of conditions and use a variety of resources. An example of a generalist is the Virginia opossum, found across much of the United States. The opossum feeds on almost anything, from eggs and dead animals to fruits and plants. In contrast, species that have narrow niches are called specialists. An example is the koala of Australia, which feeds only on the leaves of a few species of eucalyptus trees. Some species have more than one niche within a lifetime. For example, caterpillars eat the leaves of plants, but as adult butter- flies, they feed on nectar. Plants and animals are able to share the same habitats because they each have different niches.

In an ecosystem, energy flows from the sun to autotrophs, then to organisms that eat the autotrophs, and then to organisms that feed on other organisms. The amount of energy an ecosystem receives and the amount that is transferred from organism to organism affect the ecosystem’s structure. PRODUCERS Autotrophs, which include plants and some kinds of protists and bacteria, manufacture their own food. Because autotrophs cap- ture energy and use it to make organic molecules, they are called producers. Recall that organic molecules are molecules that con- tain carbon. Most producers are photosynthetic, so they use solar energy to power the production of food. However, some autotrophic bacteria do not use sunlight as an energy source. These bacteria carry out chemosynthesis (KEE-moh-SIN-thuh-sis), in which they use energy stored in inorganic molecules to produce carbohydrates. In terres- trial ecosystems, plants are usually the major producers. In aquatic ecosystems, photosynthetic protists and bacteria are usu-

Memory Adventure: From Learning to Forgetting Imagine Alex is preparing for a school science fair. Storing Memories (2.5) Alex studies a science experiment. The semantic memory (facts and knowledge, like “water boils at 100°C”) is stored in the brain, while episodic memory (personal experiences, like “I mixed vinegar and baking soda yesterday”) records the event. The hippocampus (the brain’s “save button”) helps transfer these memories into long-term memory. During sleep, memory consolidation (making memories stable and long-lasting) happens, and Alex vividly remembers the fun surprise when the mixture fizzes—a flashbulb memory (emotionally strong, vivid memory). Alex also learns the skill of carefully pouring liquids, a procedural memory stored in the basal ganglia, and how to react when the mixture splashes, a conditioned response stored in the cerebellum. Emotions make the memory even stronger, thanks to the amygdala. Retrieving Memories (2.6) The next day, Alex goes to the science fair. Seeing the experiment table triggers priming (unconscious memory activation—seeing the table makes Alex remember steps). Being in the same classroom helps context-dependent memory (better recall in the same place as learning). Alex is also in the same excited mood as while practicing, so mood-congruent memory helps remember details of the experiment. When listing the steps, Alex remembers the first step clearly and the last step best, thanks to the serial position effect. Using strategies like quizzing himself earlier (testing effect) and spacing study sessions (spacing effect) improves retrieval. Forgetting & Memory Errors (2.7) During the fair, Alex tries to remember an old trick learned last year, but some details are fuzzy. This is retroactive interference (new memories block old ones). At the same time, old steps from last year sometimes confuse him, an example of proactive interference (old memories block new info). Alex’s friend jokingly says he added glitter to the experiment last week. Alex later misremembers seeing glitter—this is the misinformation effect. He even forgets where he first learned the correct steps, a case of source amnesia, and feels a strange sense of déjà vu when looking at a similar experiment table. Unfortunately, Alex’s cousin has anterograde amnesia (cannot form new memories) and can only remember things from before last year, while his neighbor has retrograde amnesia (loses past memories) and cannot recall last week’s fair prep. Luckily, Alex’s strong study habits, sleep, and emotional engagement helped protect his memories from being forgotten too quickly.

Figure 18-11 represents the amount of energy stored as organic material in each trophic level in an ecosystem. The pyramid shape of the diagram indicates the low percentage of energy transfer from one level to the next. On average, 10 percent of the total energy consumed in one trophic level is incor- porated into the organisms in the next. Why is the percentage of energy transfer so low? One reason is that some of the organisms in a trophic level escape being eaten. They eventually die and become food for decomposers, but the energy contained in their bodies does not pass to a higher trophic level. Even when an organism is eaten, some of the molecules in its body will be in a form that the consumer cannot break down and use. For example, a cougar cannot extract energy from the antlers, hooves, and hair of a deer. Also, the energy used by prey for cellu- lar respiration cannot be used by predators to synthesize new bio- mass. Finally, no transformation or transfer of energy is 100 percent efficient. Every time energy is transformed, such as during the reactions of metabolism, some energy is lost as heat. Limitations of Trophic Levels The low rate of energy transfer between trophic levels explains why ecosystems rarely contain more than a few trophic levels. Because only about 10 percent of the energy available at one trophic level is transferred to the next trophic level, there is not enough energy in the top trophic level to support more levels. Organisms at the lowest trophic level are usually much more abundant than organisms at the highest level. In Africa, for exam- ple, you will see about 1,000 zebras, gazelles, and other herbivores for every lion or leopard you see, and there are far more grasses and shrubs than there are herbivores. Higher trophic levels con- tain less energy, so, they can support fewer individuals.A population is a group of organisms that belong to the same species and live in a particular place at the same time. All of the bass living in a pond during a certain period of time make up a pop- ulation because they are isolated in the pond and do not interact with bass living in other ponds. The boundaries of a population may be imposed by a feature of the environment, such as a lake shore, or they can be arbitrarily chosen to simplify a study of the population. The humans shown in Figure 19-1 are part of the pop- ulation of a city. The properties of populations differ from those of individuals. An individual may be born, it may reproduce, or it may die. A population study focuses on a population as a whole—how many individuals are born, how many die, and so on. Population Size A population’s size is the number of individuals that the population contains. Size is a fundamental and important population property but can be difficult to measure directly. If a population is small and composed of immobile organisms, such as plants, its size can be determined simply by counting individuals. Often, though, individ- uals are too abundant, too widespread, or too mobile to be counted easily, and scientists must estimate the number of individuals in the population. Suppose that a scientist wants to know how many oak trees live in a 10 km2 patch of forest. Instead of searching the entire patch of forest and counting all the oak trees, the scientist could count the trees in a smaller section of the forest, such as a 1 km2 area. The scientist could then use this value to estimate the population of the larger area. SECTION 1 OBJECTIVES ● Describe the main properties that scientists measure when they study populations. ● Compare the three general patterns of population dispersion. ● Identify the measurements used to describe changing populations. ● Compare the three general types of survivorship curves. VOCABULARY population population density dispersion birth rate death rate life expectancy age structure survivorship curve FIGURE 19-1 A population can be widely distributed, as Earth’s human population is, or confined to a small area, as species of fish in a lake are. Copyright © by Holt, Rinehart and Winston. All rights reserved. 382 CHAPTER 19 If the small patch contains 25 oaks, an area 10 times larger would likely contain 10 times as many oak trees. A similar kind of sampling technique might be used to estimate the size of the pop- ulation shown in Figure 19-2. To use this kind of estimate, the sci- entist must assume that the distribution of individuals in the entire population is the same as that in the sampled group. Estimates of population size are based on many such assumptions, so all esti- mates have the potential for error. Population Density Population density measures how crowded a population is. This measurement is always expressed as the number of individuals per unit of area or volume. For example, the population density of humans in the United States is about 30 people per square kilome- ter. Table 19-1 shows the population sizes and densities of humans in several countries in 2003. These estimates are calculated for the total land area. Some areas of a country may be sparsely popu- lated, while other areas are very densely populated. Dispersion A third population property is dispersion (di-SPUHR-zhuhn). Dispersion is the spatial distribution of individuals within the popu- lation. In a clumped distribution, individuals are clustered together. In a uniform distribution, individuals are separated by a fairly con- sistent distance. In a random distribution, each individual’s location is independent of the locations of other individuals in the popula- tion. Figure 19-3 illustrates the three possible patterns of dispersion. Clumped distributions often occur when resources such as food or living space are clumped. Clumped distributions may also occur because of a species’ social behavior, such as when animals gather into herds or flocks. Uniform distributions may result from social behavior in which individuals within the same habitat stay as far away from each other as possible. For example, a bird may locate its nest so as to maximize the distance from the nests of other birds. These migrating wildebeests in East Africa are too numerous and mobile to be counted. Scientists must use sampling methods at several locations to monitor changes in the population size of the animals.

Each gannet chooses a small nesting area on the coast and defends it from other gannets. In this way, each gannet tries to maximize its distance from all of its neighbors, which causes a uniform distribution of individuals. Few populations are truly randomly dispersed. Rather, they show degrees of clumping or uniformity. The dispersion pattern of a population sometimes depends on the scale at which the popu- lation is observed. The gannets shown in Figure 19-3b are uni- formly distributed on a scale of a few meters. However, if the entire island on which the gannets live is observed, the distribution appears clumped because the birds live only near the shore. POPULATION DYNAMICS All populations are dynamic—they change in size and composition over time. To understand these changes, scientists must know more than the population’s size, density, and dispersion. One important measure is the birth rate, the number of births occur- ring in a period of time. In the United States, for example, there are about 4 million births per year. A second important measure is the death rate, or mortality rate, which is the number of deaths in a

7.03 Patients with Infectious Disease The center adheres to infection control policies to ensure the safety of patients, physicians, and staff members. Patients who are currently being treated for an infectious disease or condition that is transmitted via the contact route may not be treated at the center. Patients with disease spread via droplet (e.g. influenza) or airborne (e.g. tuberculosis, measles) routes will reschedule their procedures in consultation with their physicians. The infection control nurse, in consultation with the infection control consultant, will determine whether the patient requires isolation or other additional precautions. If a patient with current Clostridium difficile-associated diarrhea is treated at the center, all rooms where the patient was housed, even briefly, should be cleaned by housekeeping under supervision of the staff at the center. Physicians must document relevant information in their pre-admission documentation. Standard Precautions will be followed in the care of all patients. Cigarroa Interventional Institute establishes policies to ensure compliance with infection control policies for the care of patients with drug-resistant organisms. The physician will screen patients through the medical history review prior to scheduling a patient at the center. During the pre-operative (pre-op) phone call or interview, a pre-op screening of the patient will be conducted. Strict isolation policies are required to treat patients with active MRSA, VRSA, or tuberculosis. Since this facility has no provisions for strict isolation, those patients with active infections will be referred elsewhere for treatment. Patients who are undergoing or completed a course of antibiotic therapy, are colonized and/or are not actively infected may be treated at the center. Patients with active infections requiring transmission-based precautions are not appropriate candidates for this facility and will be referred to another facility or rescheduled. Procedures cannot be scheduled for patients currently undergoing an infection with transmission based precautions. The patient must finish the course, and they will be rescheduled. Definitions and Standards: The following definitions and standards are provided for informational purposes only: Airborne Transmission and Precautions: This mode of transmission occurs by the spreading of either airborne droplet nuclei (small particle residue of 5 microns or smaller), of evaporated droplets which contain microorganisms that remain suspended in the air for long periods of time) or dust particles containing microorganisms. Patients must be isolated in private rooms with special air handling and ventilation, and the door must remain closed. Patient transport should be restricted to essential transport only. Respiratory precautions must be taken when in the presence of patients with active tuberculosis, including respiratory masks. Droplet Transmission and Precautions: Droplets are transmitted from the host source by coughing, sneezing, talking, or during procedures such as suctioning or bronchoscopy. Patients must be isolated, and a distance of 3 feet maintained between the infected patient and others. Caregivers within 3 feet of the patient should wear a mask. Patient transport should be minimized. Contact Transmission and Precautions: Direct contact transmission involves direct body surface to body surface contact with physical transfer of microorganisms between a susceptible host and an infected person. Indirect contact transmission involves contact with an intermediate object (usually inanimate) and a susceptible host. Patients should be isolated as much as possible. Gloves and hand washing are essential for all contact with the patient and contact with objects, which come in contact with the patient. Gloves should be changed after each contact. Reportable Condition If the patient is determined to have a reportable condition at any time during pre-admission, the Director of Operations/Nurse Manager will be notified. The procedural physician will be contacted and the case will be canceled. The Department of Health will also be notified the same day following state regulations regarding Reportable Communicable Diseases. To report a disease or condition, contact: The City of Laredo Epidemiology 24/7 Reporting Line: (956) 763-2915, if unable to report locally, call The Texas Departmrent of Health Services epidemiology program: 24/7Number for Immediately Reportable – 1-800-705-8868
