A population is defined asa group of individuals of the same species living and interbreeding within a given area. ... As a tool for objectively studying populations, population ecologists rely on a series of statistical measures, known as demographic parameters, to describe that population (Lebre...

Ecologists use population density as part of population ecology, which studies the distribution and abundance of animal and plant populations. Both low and high population densities can present challenges for a species. Increased competition for food, predation, migration, and disease are common in are...
Logistic growth is commonly observed in nature as well as in the laboratory (Figure 6), but ecologists have observed that the size of many populations fluctuates over time rather than remaining constant as logistic growth predicts. Fluctuating populations generally exhibit a period of population growth...
ecologists and conservation officials remain concerned that the concentration of the world’s wild Asiatic lions into a single and small location makes the population vulnerable todisease,forest fire, or other disastrous random events that could result in the population being wiped out. Although Asiatic...
B. Population ecologists care about the future of humanity. C. The growth of the human population is a major concern. D. Population ecology does not consider humans worthy of study. 2 According to the passage, which factor might cause the population of a species to decrease in size?
Wildlife ecologists and managers are challenged to make the most of sparse information for understanding demography of many species, especially those that ... JE Moore,AJ Read - 《Ecological Applications》 被引量: 101发表: 2008年 Natal site and offshore swimming influence fitness and long-distance...
“Anthropocenists (by that I mean the vast majority of ecologists who are concerned about the repercussions of human activity) propose that if we have the technology to so damage the planet, why can’t we turn technology to its healing? Hi-tech geo-engineering such as air cleaning plants,...
Describe how ecologists measure population size and density Identify methods used to study population changes over time Describe how life history patterns are influenced by natural selection Explain the characteristics of and differences between exponential and logistic growth patterns Compare and contrast den...
